本发明涉及一种耳机领域，特别是涉及一种具体环境声音提醒模式的耳机装置。The invention relates to the field of earphones, in particular to an earphone device in a specific environmental sound reminder mode.
【背景技术】【Background technique】
随着手机等移动互联网终端以及网络音视频软件的广泛应用，人与人之间可以越来越方便的实现随时随地的通话，鉴于通话环境的复杂性和多样性，人们在进行通话时也就越来越多地可能处于噪声环境之下，通话环境中的噪声对于通话质量的负面影响日益明显。比如在喧闹的街道、房间和广场中，又或者在汽车、火车等交通工具中，周围背景噪声对于通话双方的通话质量的负面影响有时会非常严重。而对于佩带耳机聆听音乐、观赏电影或进行电玩游戏的便携多媒体数码设备使用者，噪声对于用户的使用体验的负面影响则会更加让人无法忍受。另外，在一些场合下，人们往往不希望通话的对方听到自己所处的环境。With the wide application of mobile Internet terminals such as mobile phones and network audio and video software, it is more and more convenient to realize calls anytime and anywhere between people. In view of the complexity and diversity of the call environment, people also It is more and more likely to be in a noisy environment, and the negative impact of noise in the call environment on the call quality is becoming more and more obvious. For example, in noisy streets, rooms, and squares, or in vehicles such as cars and trains, the negative impact of surrounding background noise on the call quality of both parties is sometimes very serious. For users of portable multimedia digital devices who wear earphones to listen to music, watch movies or play video games, the negative impact of noise on the user experience will be even more unbearable. In addition, in some occasions, people often do not want the other party on the call to hear the environment in which they are.
目前耳机的应用非常广泛，多数情况下，人们会通过耳机来通话和听音乐等。然而，人们一般带着耳机听音乐或通话时，自己发出的声音会比较大，这是因为带着耳机时，大脑不能获知外界环境音量，而只能将耳机里播放的声音作为环境音量，因此如果耳机播放的声音比较响，大脑据此判断当前环境比较响，就自动控制说话人提高嗓门。另外，由于耳机一般都采用了一些被动降噪设计，譬如采用隔音材料制成入耳式耳机、头戴式耳机等。用户在使用这些耳机时，环境声音被隔离，因此用户听到的自己发出的语音是很小的，甚至听不清。这时用户会误解自己的声音很小，而不自觉地就加大的声音音量。At present, earphones are widely used. In most cases, people use earphones to talk and listen to music. However, when people wear earphones to listen to music or talk, their own voice will be louder. This is because when wearing earphones, the brain cannot know the volume of the external environment, but can only use the sound played in the earphones as the ambient volume. If the sound played by the earphone is relatively loud, the brain judges that the current environment is relatively loud based on this, and automatically controls the speaker to raise the voice. In addition, because earphones generally adopt some passive noise reduction designs, such as in-ear earphones and headphones made of sound-proof materials. When the user uses these headphones, the ambient sound is isolated, so the user's own voice heard by the user is very small, or even inaudible. At this time, the user will misunderstand that his voice is very low, and unconsciously increase the volume of the voice.
因此，有必要提出一种改进的技术方案来解决上述问题。Therefore, it is necessary to propose an improved technical solution to solve the above problems.

There may be multiple keys or one key. The command interface 160 can also be a voice recognition interface. The user speaks a preset voice control command, and the voice recognition interface recognizes the voice control command and sends an instruction to the microprocessing unit to enter a corresponding mode.
本发明中的耳机装置100的特点、优点之一在于：所述微处理单元130具有一个或多个功能模式，每个功能模式都具有自己对应的控制指令。下面将逐一介绍一下所述耳机装置100的新增的功能模式。One of the characteristics and advantages of the earphone device 100 in the present invention is that: the micro-processing unit 130 has one or more functional modes, and each functional mode has its own corresponding control instruction. The newly added function modes of the earphone device 100 will be introduced one by one below.
环境声音提醒模式Ambient sound reminder mode
在一个实施例中，所述微处理单元130具有环境声音提醒模式，此时，所述控制指令包括进入环境声音提醒模式指令和退出环境声音提醒指令。In one embodiment, the micro-processing unit 130 has an ambient sound reminder mode, at this time, the control instruction includes an instruction to enter the ambient sound reminder mode and an instruction to exit the ambient sound reminder mode.
图2为本发明中的耳机装置的环境声音提醒模式的功能流程图。如图2所示的，在步骤210处判断是否收到环境声音提醒模式指令，在收到进入环境声音提醒模式指令后，所述微处理单元在步骤220处进入环境声音提醒模式。FIG. 2 is a functional flowchart of the ambient sound reminder mode of the earphone device in the present invention. As shown in FIG. 2 , at step 210 it is judged whether an ambient sound reminder mode instruction is received, and after receiving the ambient sound reminder mode instruction, the micro-processing unit enters the ambient sound reminder mode at step 220 .
在环境声音提醒模式下，进入步骤230，利用第一麦克风110采集环境声音，随后进入步骤240，将采集的环境声音实时的通过所述扬声器150播放，以提醒用户当前实时的环境声音。当然，在可选择的实施例中，也可以选用第二麦克风120来采集环境声音。需要注意的是，第一麦克风110或第二麦克风120采集的环境声音会被实时的、及时的通过所述扬声器150播放，而不是先录制一段时间的环境声音，再播放录制的环境声音，这样可以使得用户尽可能的听到实时的环境声音，而不会有较为明显的延迟。从所述环境声音被采集，到所述环境声音被扬声器播放，相隔的延迟时间很短，比如延迟时间可以小于1秒。在一个实例中，可以利用缓存器缓存采集的环境声音，随后将缓存的环境声音实时的通过扬声器播放。In the ambient sound reminder mode, enter step 230, use the first microphone 110 to collect ambient sound, then enter step 240, and play the collected ambient sound through the speaker 150 in real time to remind the user of the current real-time ambient sound. Certainly, in an optional embodiment, the second microphone 120 may also be selected to collect ambient sound. It should be noted that the ambient sound collected by the first microphone 110 or the second microphone 120 will be played through the speaker 150 in real time and in a timely manner, instead of first recording the ambient sound for a period of time, and then playing the recorded ambient sound. The user can hear the real-time ambient sound as much as possible without obvious delay. The delay time between when the ambient sound is collected and when the ambient sound is played by the loudspeaker is very short, for example, the delay time may be less than 1 second. In an example, the buffer may be used to buffer the collected ambient sound, and then the buffered ambient sound is played through the speaker in real time.
随后进入步骤250，判断是否收到退出环境声音提醒模式指令，在收到退出环境声音提醒模式指令后，所述微处理单元在步骤260退出环境声音提醒模式。在另一个可选择的实施例中，在环境声音提醒模式持续预定时长后，可以自动退出环境声音提醒模式，此时可以没有退出环境声音提醒模式指令。当然，还可以采用其他的方式，退出环境声音提醒模式。Then enter step 250, judge whether to receive the instruction of exiting the environmental sound reminder mode, after receiving the instruction of exiting the environment sound reminder mode, the micro-processing unit exits the environment sound reminder mode in step 260. In another optional embodiment, after the ambient sound reminder mode lasts for a predetermined period of time, the ambient sound reminder mode may be automatically exited, and there may be no instruction to exit the ambient sound reminder mode at this time. Of course, other ways can also be used to exit the ambient sound reminder mode.
这样，在用户佩戴耳机装置听音乐或打通话时，如果需要跟其他人打招呼，或者说话，只需要通过命令接口160发出环境声音提醒模式指令，就可以使得耳机装置进入环境声音提醒模式，此时用户不用摘下耳机也可以听到外部的环境声音，比如其他人的声音，还可以用正常的音量与其他人交流，大大方便了人们的使用。在现实生活中经常可以看到，佩戴耳机听音乐的用户在跟其他人交流时，需要摘下耳机才能够听清楚其他人的声音，才能够用正常音量跟他人交流，而在本发明中则完全可以不摘下耳机装置。In this way, when the user wears the earphone device to listen to music or make a call, if he needs to greet or talk to other people, he only needs to issue an ambient sound reminder mode command through the command interface 160, and the earphone device can enter the ambient sound reminder mode. Users do not need to take off the earphones to hear external ambient sounds, such as other people's voices, and can also communicate with other people at a normal volume, which greatly facilitates people's use. It can often be seen in real life that when a user wearing earphones and listening to music communicates with other people, he needs to take off the earphones to hear the voices of other people clearly and to communicate with others at a normal volume. It is not necessary to take off the earphone unit at all.
在所述命令接口160是按键时，可以通过触发该按键而发出进入环境声音提醒模式指令和/或退出环境声音提醒模式指令，该按键可以是耳机上新增的特定按键，比如按下特定按键表示进入环境声音提醒模式指令，再按一下该特定按键表示退出环境声音提醒模式指令；亦可是为耳机上的常规按键设定特定的操作方式后形成的“特定按键”，比如连续按3次耳机上的音量+按键，则进入环境声音提醒模式。也就是说，假如正在通话中的用户担心自己说话的声音太大，只需要按下特定按键，就可以收听自己所处的环境声音，并根据环境声音的大小调整自己说话时的音量了。这种应用对于带着耳机学唱的用户同样实用。我们知道，现在的音乐发烧友们带着耳机跟唱时，常常因为自己听不到或听不清自己发出的声音，实际跟唱时总是跑调而遭到周围人的讥笑和嫌弃。本发明的耳机装置所提供的环境声音提醒模式，可以让跟唱者在佩戴耳机后，既听到音乐原声，又可听到自己跟唱的声音，使得跟唱者可及时修正自己的歌声。因此，本发明在使用耳机通话或收听音乐等语音内容的同时，可通过耳机装置实时录制并收听自己周围的环境声音以及自己发出的声音，从而为使用者营造一个仿佛没有佩戴耳机的语音环境，其操作简单、使用方便，并可免除一些不必要的尴尬。When the command interface 160 is a button, the button can be triggered to issue an instruction to enter the ambient sound reminder mode and/or an instruction to exit the ambient sound reminder mode. The button can be a new specific button on the earphone, such as pressing a specific button Indicates the command to enter the ambient sound reminder mode, and then press the specific button to indicate the command to exit the ambient sound reminder mode; it can also be a "specific button" formed after setting a specific operation mode for the conventional button on the earphone, such as pressing the earphone 3 times in a row Press the volume + button on the phone to enter the ambient sound reminder mode. That is to say, if the user who is on the call is worried that his voice is too loud, he only needs to press a specific button to listen to the sound of his environment, and adjust the volume of his speech according to the size of the environment sound. This kind of application is also practical for users who are learning to sing with headphones. We know that when music enthusiasts sing along with headphones, they are often ridiculed and disgusted by the people around them because they cannot hear or clearly hear their own voices, and they are always out of tune when they actually sing along. The ambient sound reminder mode provided by the earphone device of the present invention allows the follower to hear the original sound of the music and the sound of his own singing after wearing the earphone, so that the follower can correct his own singing voice in time. Therefore, the present invention can record and listen to the ambient sound around oneself and the sound emitted by oneself in real time through the earphone device while using the earphone to talk or listen to voice content such as music, thereby creating a voice environment for the user as if not wearing earphones, Its operation is simple, easy to use, and can avoid some unnecessary embarrassment.
在所述命令接口为语音识别接口时，可以事先在所述语音识别接口中为各个语音控制指令训练多个语音控制指令模板，之后用户说出预先设定的语音控制指令，从而使所述语音识别接口能识别该语音控制命令。具体来说，用户为进入环境声音提醒模式指令事先训练一个语音控制指令模板，用户多次说出“进入环境声音提醒模式”这一段话，之后在正式使用时，用户说出“进入环境声音提醒模式”时，所述语音识别接口就能够识别出是“进入环境声音提醒模式指令”。基于同样的方式，也可以用户为退出环境声音提醒模式指令事先训练一个语音控制指令模板，之后就可以通过语音来发出退出环境声音提醒模式指令了。在应用时，用户希望跟其他人交流时，只需要说出“进入环境声音提醒模式”，就可以听到外部环境声音，可以与他人正常的交流了，交流完毕后，只要说出“退出环境声音提醒模式”就可以退出环境声音提醒模式。When the command interface is a speech recognition interface, a plurality of speech control instruction templates can be trained for each speech control instruction in the speech recognition interface in advance, and then the user speaks a preset speech control instruction, so that the speech The recognition interface can recognize the voice control command. Specifically, the user trained a voice control command template in advance to enter the ambient sound reminder mode instruction. The user said "Enter the ambient sound reminder mode" many times, and then in official use, the user said "Enter the ambient sound reminder mode". mode", the voice recognition interface can recognize that it is an "instruction to enter the ambient sound reminder mode". Based on the same method, the user can also train a voice control instruction template in advance for the command to exit the ambient sound reminder mode, and then the user can issue an instruction to exit the ambient sound reminder mode by voice. In the application, when the user wants to communicate with other people, he only needs to say "Enter the environment sound reminder mode", and then he can hear the external environment sound, and can communicate with others normally. After the communication, just say "Exit the environment Sound reminder mode" to exit the ambient sound reminder mode.
在一个实施例中，在环境声音提醒模式下，可以暂停当前需要在所述扬声器中播放的音频信号的播放。比如，用户正在听音乐，在进入环境声音提醒模式后，可以暂停当前正在播放的音乐，而开始播放录制的环境声音。在退出环境声音提醒模式后，恢复当前需要在所述扬声器中播放的音频信号的播放。In one embodiment, in the ambient sound reminder mode, the playback of the audio signal currently to be played in the speaker may be suspended. For example, when the user is listening to music, after entering the ambient sound reminder mode, the currently playing music can be paused and the recorded ambient sound can be played. After exiting the ambient sound reminder mode, resume the playback of the audio signal currently to be played in the speaker.
在一个优选的实施例中，所述耳机装置为立体声耳机装置，所述扬声器150包括左声道扬声器和右声道扬声器。在环境声音提醒模式下，当前需要播放的音频信号可以通过左声道扬声器和右声道扬声器中的一个进行播放，同时可以将采集的环境声音实时的通过左声道扬声器和右声道扬声器中的另一个进行播放。这样既可以听到当前正在播放的音乐，又可以听到外界环境声音，给用户更好的体验。In a preferred embodiment, the earphone device is a stereo earphone device, and the speaker 150 includes a left channel speaker and a right channel speaker. In the ambient sound reminder mode, the audio signal that needs to be played can be played through one of the left channel speaker and the right channel speaker, and at the same time, the collected ambient sound can be passed through the left channel speaker and the right channel speaker in real time. another one to play. In this way, you can not only hear the music currently being played, but also hear the sound of the external environment, giving users a better experience.
在一个优选的实施例中，微处理单元130对第一麦克风采集110的第一声音信号进行语音检测(Voice Activity Detection，语音活动检测)，在检测到语音时，则发出进入环境声音提醒模式指令，使得所述微处理单元130进入环境声音提醒模式。这样，不需要通过命令接口160输入控制指令，也可以使得所述微处理单元130进入环境声音提醒模式。In a preferred embodiment, the microprocessing unit 130 performs voice detection (Voice Activity Detection, voice activity detection) on the first sound signal collected by the first microphone 110, and when a voice is detected, an instruction to enter the ambient sound reminder mode is issued , so that the micro-processing unit 130 enters the ambient sound reminder mode. In this way, the micro-processing unit 130 can also be made to enter the ambient sound reminder mode without inputting a control command through the command interface 160 .
在一个实施例中，可以设置每次环境声音提醒模式能够维持预定时长，在环境声音提醒模式维持了预定时长后，能够自动退出所述环境声音提醒模式。In one embodiment, it can be set that the ambient sound reminder mode can be maintained for a predetermined time each time, and the ambient sound reminder mode can be automatically exited after the environmental sound reminder mode is maintained for a predetermined time period.

在一个实施例中，所述微处理单元130具有分贝提醒模式，此时，所述控制指令可以包括进入分贝提醒模式指令，在收到进入分贝提醒模式指令后，所述微处理单元进入分贝提醒模式。在分贝提醒模式时，微处理单元130检测得到用户听到的声音的分贝值，并通过所述扬声器播报所述分贝值。在另一个实施例中，所述微处理单元130可以一直处于所述分贝提醒模式下，而不需要相应的指令才进入。In one embodiment, the microprocessing unit 130 has a decibel reminder mode. At this time, the control instruction may include an instruction to enter the decibel reminder mode. After receiving the instruction to enter the decibel reminder mode, the microprocessing unit enters the decibel reminder mode. model. In the decibel reminder mode, the micro-processing unit 130 detects the decibel value of the sound heard by the user, and broadcasts the decibel value through the speaker. In another embodiment, the micro-processing unit 130 can be in the decibel alert mode all the time, without corresponding instruction to enter.
在一个实施例中，所述控制指令还可以包括退出分贝提醒模式指令，在收到退出分贝提醒模式指令后，所述微处理单元退出分贝提醒模式。在另一个可选择的实施例中，在分贝提醒模式指令持续预定时长，或者，播报完分贝值之后，可以自动退出环境声音提醒模式。当然，还可以采用其他的方式，退出分贝提醒模式。In one embodiment, the control instruction may also include an instruction to exit the decibel alert mode, and after receiving the instruction to exit the decibel alert mode, the micro-processing unit exits the decibel alert mode. In another optional embodiment, after the decibel reminding mode instruction lasts for a predetermined period of time, or after the decibel value is broadcast, the ambient sound reminding mode can be automatically exited. Of course, other ways can also be used to exit the decibel reminder mode.
分贝提醒模式可以在微处理单元处于其它功能模式下时被同时启动，以便可以随时监控传入用户耳朵内的声音的分贝值，保护用户听力。The decibel reminder mode can be started simultaneously when the micro-processing unit is in other functional modes, so that the decibel value of the sound incoming to the user's ear can be monitored at any time to protect the user's hearing.
图3为所述微处理单元130在一个实施例中的结构框图。如图3所示的，所述微处理单元130包括分贝值形成单元131和分贝语音形成单元132。所述分贝值形成单元131用于在分贝提醒模式时根据用户听到的声音得到其分贝值，所述分贝语音形成单元132用于分贝提醒模式时对所述分贝值形成单元131形成的分贝值进行语音合成得到分贝语音信号，并将所述分贝语音信号发送给所述扬声器播放。FIG. 3 is a structural block diagram of the micro-processing unit 130 in an embodiment. As shown in FIG. 3 , the micro-processing unit 130 includes a decibel value forming unit 131 and a decibel voice forming unit 132 . The decibel value forming unit 131 is used to obtain the decibel value according to the sound heard by the user in the decibel reminder mode, and the decibel voice forming unit 132 is used to form the decibel value of the decibel value forming unit 131 in the decibel reminder mode. Speech synthesis is performed to obtain a decibel voice signal, and the decibel voice signal is sent to the speaker for playback.
在一个实施例中，如图1所示的，所述耳机装置100还包括在所述耳机装置被佩戴于用户头上时靠近用户的耳孔的第三麦克风(未图示)。图4为本发明中的耳机装置的分贝提醒模式在一个实施例中的功能流程图。如图4所示的，在分贝提醒模式时，在步骤410处，由第三麦克风180采集用户的耳孔附近的声音，随后在步骤420处，计算第三麦克风采集的声音的分贝值。第三麦克风180采集到的声音可以包括所述扬声器150播放出来的声音，也可以包括外部环境传到用户的耳孔附近的声音。随后，在步骤430，对计算得到的分贝值进行语音合成得到分贝语音信号。最后，在步骤440，由扬声器播报所述分贝语音信号。这样，用户就可以听到分贝值提醒，从而保护用户的耳朵，假如声音超过80分贝，用户可能就会降低音量，或者在此区域少做停留。在此实施例中，所述耳机装置优选为头戴式耳机装置，而不是入耳式耳机装置，这样可以有足够的空间来放置所述第三麦克风180。In one embodiment, as shown in FIG. 1 , the earphone device 100 further includes a third microphone (not shown) close to the user's earhole when the earphone device is worn on the user's head. FIG. 4 is a functional flowchart of an embodiment of the decibel reminder mode of the earphone device in the present invention. As shown in FIG. 4 , in the decibel reminder mode, at step 410 , the third microphone 180 collects the sound near the earhole of the user, and then at step 420 , calculates the decibel value of the sound collected by the third microphone. The sound collected by the third microphone 180 may include the sound played by the speaker 150 , and may also include the sound transmitted from the external environment to the vicinity of the user's ear hole. Subsequently, in step 430, speech synthesis is performed on the calculated decibel value to obtain a decibel speech signal. Finally, in step 440, the decibel voice signal is broadcast by the speaker. In this way, the user can hear the decibel value reminder to protect the user's ears. If the sound exceeds 80 decibels, the user may lower the volume or stay less in this area. In this embodiment, the earphone device is preferably a headphone device rather than an earphone device, so that there is enough space for placing the third microphone 180 .
在另一个可选择的实施例中，所述存储单元180中存储有该耳机装置的输出功耗和用户听到的声音的分贝值的对应关系，输出功耗越大，对应的分贝值也会越大。该对应关系可以通过事先测试得到，具体的，使得所述耳机装置的输出功耗处于不同值下，在所述输出功耗处于一个值下时，用专业的分贝值测量设备测量所述扬声器150处的分贝值，记录下该输出功耗的值与所述分贝值的对应关系。在分贝提醒模式时，分贝值形成单元131检测该耳机装置的输出功耗，并通过该耳机装置的输出功耗和用户听到的声音的分贝值的对应关系找到用户当前所听到的声音的分贝值，此时主要考虑所述扬声器150所需播放的音频信号的影响，扬声器150所播放的音频信号可以是来自外部电子设备的音频信号，或者是来自第一麦克风110的音频信号，或者是来自第二麦克风120的音频信号；亦可以是所述微处理单元130基于第二声音信号对第一声音信号进行降噪处理，以消除第一声音信号中的环境噪声，并将降噪处理后的声音信号输出至所述扬声器150以作为所述扬声器150所需播放的音频信号，或者将降噪处理后的声音信号与来自外部电子设备的音频信号进行混合后输出至所述扬声器150以作为所述扬声器150所需播放的音频信号。In another optional embodiment, the storage unit 180 stores the corresponding relationship between the output power consumption of the headphone device and the decibel value of the sound heard by the user. The greater the output power consumption, the corresponding decibel value will be bigger. This corresponding relationship can be obtained through prior testing, specifically, the output power consumption of the earphone device is at different values, and when the output power consumption is at a value, the loudspeaker 150 is measured with professional decibel value measuring equipment. record the corresponding relationship between the value of the output power consumption and the decibel value. When in the decibel reminder mode, the decibel value forming unit 131 detects the output power consumption of the earphone device, and finds the value of the sound that the user is currently hearing through the corresponding relationship between the output power consumption of the earphone device and the decibel value of the sound heard by the user. decibel value, at this time, the influence of the audio signal to be played by the speaker 150 is mainly considered. The audio signal played by the speaker 150 may be an audio signal from an external electronic device, or an audio signal from the first microphone 110, or an audio signal from the first microphone 110. The audio signal from the second microphone 120; it can also be that the micro-processing unit 130 performs noise reduction processing on the first sound signal based on the second sound signal, so as to eliminate the environmental noise in the first sound signal, and the noise reduction processing output the sound signal to the speaker 150 as the audio signal to be played by the speaker 150, or mix the noise-reduced sound signal with the audio signal from an external electronic device and output it to the speaker 150 as an audio signal to be played by the speaker 150. The audio signal that the speaker 150 needs to play.
在一个更为优选的实施例中，所述存储单元180中还存储有预定分贝阈值以及预定分贝阈值对应的持续时间阈值，在所述微处理器130检测到的分贝值超过预定分贝阈值且持续超过预定分贝阈值对应的持续时间阈值时，则可以播报检测到的所述分贝值，也可以自动降低扬声器150的音量，还可以自动停止当前音频信号的播放。这样可以更好的保护用户的听力。In a more preferred embodiment, the storage unit 180 also stores a predetermined decibel threshold and a duration threshold corresponding to the predetermined decibel threshold, and the decibel value detected by the microprocessor 130 exceeds the predetermined decibel threshold and lasts When the duration threshold corresponding to the predetermined decibel threshold is exceeded, the detected decibel value may be broadcast, the volume of the speaker 150 may be automatically reduced, or the playback of the current audio signal may be automatically stopped. This can better protect the user's hearing.
在一个实施例中，在分贝提醒模式时，每隔预定时长播报一次分贝值。比如，每隔20秒播报一次分贝值。在另一个实施例中，在分贝提醒模式时，在微处理单元130基于第三麦克风采集的声音得到的分贝值超过预定分贝阈值(比如80分贝、90分贝等)时，会通过所述扬声器150播报所述分贝值。In one embodiment, in the decibel reminder mode, the decibel value is broadcast every predetermined time. For example, broadcast a decibel value every 20 seconds. In another embodiment, in the decibel reminder mode, when the decibel value obtained by the micro-processing unit 130 based on the sound collected by the third microphone exceeds a predetermined decibel threshold (such as 80 decibels, 90 decibels, etc.), it will pass through the speaker 150. Announces the decibel value.
在所述命令接口160是按键时，可以通过触发该按键而发出进入分贝提醒模式指令或退出分贝提醒模式指令，该按键可以是耳机上新增的特定按键，亦可是为耳机上的常规按键设定特定的操作方式后形成的“特定按键”。比如触发特定按键表示进入分贝提醒模式指令，再次触发该特定按键表示退出分贝提醒模式指令。也就是说，假如用户希望知道目前听到的声音的高低时，只需要触发特定按键就可以了，扬声器150中就会播报此时的分贝值，可以再触发特定按键就可以退出分贝提醒模式指令。当然，也可以在播报完此次分贝值后，自动退出分贝提醒模式。When the command interface 160 is a button, the button can be triggered to issue an instruction to enter the decibel reminder mode or to exit the decibel reminder mode. A "specific button" formed after a specific operation mode is determined. For example, triggering a specific button means entering the decibel reminder mode command, and triggering the specific button again means exiting the decibel reminder mode command. That is to say, if the user wishes to know the level of the sound heard at present, he only needs to trigger a specific key, and the speaker 150 will broadcast the decibel value at this time, and the decibel reminder mode command can be exited by triggering the specific key again. . Of course, it is also possible to automatically exit the decibel reminder mode after the decibel value is broadcast this time.
在所述命令接口为语音识别接口时，可以事先在所述语音识别接口中为各个语音控制指令训练多个语音控制指令模板，之后用户说出预先设定的语音控制指令，所述语音识别接口就能识别该语音控制命令。具体来说，用户为进入分贝提醒模式指令事先训练一个语音控制指令模板，用户多次说出“进入分贝提醒模式”这一段话，之后在正式使用时，用户说出“进入分贝提醒模式”时，所述语音识别接口就能够识别出是“进入分贝提醒模式”。基于同样的方式，也可以用户为退出分贝提醒模式指令事先训练一个语音控制指令模板。When the command interface is a speech recognition interface, a plurality of speech control instruction templates can be trained for each speech control instruction in the speech recognition interface in advance, and then the user speaks a preset speech control instruction, and the speech recognition interface The voice control command will be recognized. Specifically, the user trained a voice control command template in advance to enter the decibel reminder mode instruction. The user said the phrase "enter the decibel reminder mode" many times, and then in official use, when the user said "enter the decibel reminder mode" , the voice recognition interface can recognize that it is "entering the decibel reminder mode". Based on the same method, the user may also train a voice control command template in advance for the command to exit the decibel reminder mode.
本地通话情况确认模式Local call status confirmation mode
在一个实施例中，本发明的耳机装置100可具有双麦克风降噪功能，即所述第一麦克风110采集第一声音信号，所述第二麦克风120采集第二声音信号，所述微处理单元130基于第二声音信号对第一声音信号进行降噪处理，以消除第一声音信号中的环境噪声，这样，第一声音信号可以更清晰地传输给远端的通话对方者，从而提高了语音通话的质量。In one embodiment, the earphone device 100 of the present invention may have a dual-microphone noise reduction function, that is, the first microphone 110 collects a first sound signal, the second microphone 120 collects a second sound signal, and the micro-processing unit 130. Perform noise reduction processing on the first sound signal based on the second sound signal, so as to eliminate the environmental noise in the first sound signal. In this way, the first sound signal can be transmitted to the far-end caller more clearly, thereby improving the voice quality. The quality of the call.
本发明的耳机装置100还可具有主动降噪功能，即所述第二麦克风120采集第二声音信号，所述微处理单元130基于第二声音信号产生一个与之相反的反噪声波形，并通过扬声器播放该反噪声声波，从而达到抵消环境噪声的目的。这样的耳机装置100通过主动噪声消除与被动降噪设计相结合的方式，大幅度地消除了环境噪声对耳机使用者的影响，可以获得更清晰的收听效果。The earphone device 100 of the present invention can also have an active noise reduction function, that is, the second microphone 120 collects a second sound signal, and the micro-processing unit 130 generates an opposite anti-noise waveform based on the second sound signal, and passes The speaker broadcasts this anti-noise sound wave, thereby canceling out the ambient noise. Such earphone device 100 greatly eliminates the impact of environmental noise on the earphone user through the combination of active noise cancellation and passive noise reduction, and can obtain a clearer listening effect.
但是，现有的双麦克风降噪功能因降噪算法、不同环境下的噪声特殊性等各种原因造成降噪效果并不稳定。而主动降噪功能使得耳机使用者更无法清晰听到自己发出的声音了。在一些特定的应用场合下，耳机使用者完全不希望通话对方听到自己所处的环境声音，譬如会议中接听电话时，不想让对方听到任何会议内容，此时，耳机使用者可能因为不能确认耳机的双麦克风降噪功能是否确实有用，或者需要确保对方只听到了自己愿意他听到的内容，而不得不必须离开会议现场。在另一些特定的应用场合下，耳机使用者也需要及时收听自己发出的声音，以控制音量大小、矫正发音等。However, the noise reduction effect of the existing dual-microphone noise reduction function is not stable due to various reasons such as noise reduction algorithms and noise characteristics in different environments. The active noise reduction function makes it even more difficult for headphone users to hear their own voice clearly. In some specific applications, the headset user does not want the other party to hear the sound of the environment in which he is at all. For example, when answering a call in a meeting, he does not want the other party to hear any meeting content. Find out if the headset's dual-mic noise-canceling feature actually works, or if you need to make sure the other person only hears what you want him to hear, and you have to leave the meeting. In other specific applications, earphone users also need to listen to their own voices in time to control the volume and correct pronunciation.
