音量管理系统及方法Volume management system and method

技术领域technical field

本发明有关一种音量管理方法，特别是有关一种调整手持式通讯装置的输出音量的音量管理方法。The present invention relates to a volume management method, in particular to a volume management method for adjusting the output volume of a handheld communication device.

背景技术Background technique

随着移动科技的发展，手机已是大部分人必备的通讯工具。然而，在吵杂的环境下、或是听力较差的使用者在讲手机的时候，常会因为听不清楚对方的声音而不自觉地加大自己说话的音量。如此一来，不仅会吵到周围的人，也会导致传到对方的音量太大。With the development of mobile technology, mobile phones have become an essential communication tool for most people. However, in a noisy environment, or when a user with poor hearing is talking on a mobile phone, they often unconsciously increase the volume of their speech because they cannot hear the other party's voice clearly. In this way, not only will the people around you be noisy, but the volume transmitted to the other party will also be too loud.

为了让使用者能清楚地由手机的听筒(Receiver)听到对方的声音，一般来说，目前有手动及自动调整听筒音量两种已知技术。In order to allow the user to clearly hear the voice of the other party through the receiver of the mobile phone, generally speaking, there are currently two known techniques for manually and automatically adjusting the volume of the receiver.

在手动调整听筒音量部份，使用者在通话时，若欲调整手机听筒的输出音量，可直接通过手机上所提供的“音量调整按键”来控制听筒的输出音量的大小。借此，当使用者在吵杂的环境下讲电话时，需手动调大听筒音量，才能清楚听到对方的声音；而在安静的环境下(例如：在会议中)，需手动调小听筒音量，以避免听筒的输出音量干扰到使用者以外的人。In the part of manually adjusting the volume of the handset, if the user wants to adjust the output volume of the handset during a call, he can directly control the output volume of the handset through the "volume adjustment button" provided on the handset. In this way, when the user is talking on the phone in a noisy environment, the user needs to manually increase the volume of the earpiece to hear the other party's voice clearly; in a quiet environment (for example: in a meeting), the user needs to manually turn down the volume of the earpiece volume to prevent the output volume of the earpiece from disturbing people other than the user.

在自动调整听筒音量部份，此种手机具有内建的分贝器，可检测到环境噪音，并依据环境噪音的大小，来自动调整听筒音量。例如：当环境噪音较大时，手机会自动增加听筒音量；当环境噪音较小时，手机会自动降低听筒音量。In the part of automatically adjusting the volume of the earpiece, this kind of mobile phone has a built-in decibel meter, which can detect the environmental noise, and automatically adjust the volume of the earpiece according to the size of the environmental noise. For example: when the ambient noise is high, the mobile phone will automatically increase the earpiece volume; when the ambient noise is low, the mobile phone will automatically reduce the earpiece volume.

关于本发明的优点与精神，以及更详细的实施方式可以通过以下参照附图对较佳实施方式的描述得到进一步的了解。The advantages and spirit of the present invention, as well as more detailed implementations, can be further understood through the following description of preferred implementations with reference to the accompanying drawings.

附图说明Description of drawings

通过以下详细的描述结合所附图示，将可轻易的了解上述内容及此项发明的诸多优点，其中：Through the following detailed description in conjunction with the accompanying drawings, the above contents and many advantages of the present invention can be easily understood, wherein:

图1为本发明音量管理系统的配置图；及Fig. 1 is a configuration diagram of the volume management system of the present invention; and

图2为本发明音量管理方法的作用流程图。Fig. 2 is a flow chart of the volume management method of the present invention.

具体实施方式Detailed ways

依据人类的行为模式发现：人类说话的音量，和说话者的听力以及对方说话的音量成反比。According to human behavior patterns, it is found that the volume of human speech is inversely proportional to the speaker's hearing and the volume of the other party's speech.

举例来说：for example:

听力不好的人，因为听不清楚对方的声音，所以会不自觉地放大自己说话的音量；或者在吵杂的环境中接听电话时，使用者也会因为听不清楚对方的声音，而放大说话的音量。People with poor hearing will unconsciously amplify the volume of their speech because they cannot hear the other party's voice clearly; speaking volume.

因此，在使用手机通话时，当使用者说话愈大声，即代表愈听不清楚手机听筒所发出的声音。此时，听筒音量就应放大，让使用者可清楚且轻易地听到听筒所发出的声音，进而使使用者降低说话的音量。Therefore, when using a mobile phone to talk, the louder the user speaks, the harder it is to hear the sound from the handset of the mobile phone. At this time, the volume of the earpiece should be amplified, so that the user can clearly and easily hear the sound from the earpiece, so that the user can lower the volume of speaking.

另外，当使用者说话小声，即代表使用者听得很清楚或者使用者处于一个很安静的环境(或会议)中，可能不希望听筒的声音太大而干扰到其它人。此时，听筒音量就应降低。In addition, when the user speaks softly, it means that the user can hear clearly or the user is in a very quiet environment (or meeting), and may not want the earpiece to be too loud to disturb other people. At this point, the earpiece volume should be lowered.

本发明的音量管理方法，亦即依据上述的行为模式及相关推论所发展出来的，且其音量管理的依据为使用者的说话音量。The volume management method of the present invention is developed based on the above-mentioned behavior patterns and related inferences, and the volume management is based on the user's speaking volume.

请参照图1，其为本发明音量管理系统的配置图。本发明的音量管理系统10，适用于一手持式通讯装置(例如：手机)，音量管理系统10至少包括一声音接收元件11、一声音播放元件12、一储存单元13及一音量管理单元14。Please refer to FIG. 1 , which is a configuration diagram of the volume management system of the present invention. Thevolume management system 10 of the present invention is suitable for a handheld communication device (such as a mobile phone). Thevolume management system 10 at least includes asound receiving component 11 , asound playing component 12 , astorage unit 13 and avolume management unit 14 .

声音接收元件11用以接收一输入声音信号，例如：一使用者的说话声音。声音播放元件12用以产生一输出声音信号。储存单元13则用以储存一预设平均音量。Thesound receiving element 11 is used for receiving an input sound signal, such as a user's speaking sound. Thesound playing component 12 is used for generating an output sound signal. Thestorage unit 13 is used for storing a preset average volume.

音量管理单元14用以分析输入声音信号取得一接收音量，进而比较接收音量与预设平均音量以调整输出声音信号的一输出音量。Thevolume management unit 14 is used to analyze the input audio signal to obtain a received volume, and then compare the received volume with a preset average volume to adjust an output volume of the output audio signal.

其中，当接收音量约等于预设平均音量时，音量管理单元14将维持声音播放元件12的输出音量；当接收音量大于预设平均音量时，音量管理单元14将增加声音播放元件12的输出音量；当接收音量小于预设平均音量时，音量管理单元14将降低声音播放元件12的输出音量。在一实施例中，当上述输入声音信号为使用者的说话声音时，接收音量即为使用者目前的说话音量。Wherein, when the receiving volume is approximately equal to the preset average volume, thevolume management unit 14 will maintain the output volume of thesound playing element 12; when the receiving volume is greater than the preset average volume, thevolume management unit 14 will increase the output volume of thesound playing element 12 ; When the received volume is lower than the preset average volume, thevolume management unit 14 will reduce the output volume of thesound playing component 12 ; In one embodiment, when the input audio signal is the user's speaking voice, the received volume is the user's current speaking volume.

在使用者的通话过程中，音量管理单元14可设定每隔一特定时间(约数秒钟)便再次检测且取得输入声音信号，以随时调整声音播放元件12的输出音量。During the user's conversation, thevolume management unit 14 can be set to detect and obtain the input audio signal again at a specific time interval (about several seconds), so as to adjust the output volume of theaudio playback component 12 at any time.

而当通话结束时，音量管理单元14会将本次通话过程中，所取得的接收音量作平均，以获得一平均接收音量。When the call ends, thevolume management unit 14 averages the received volumes obtained during the current call to obtain an average received volume.

接着将此平均接收音量与原本储存于储存单元13的预设平均说话音量作平均，并将上述平均值储存至储存单元13，以取代原本的预设平均音量，作为下一次通话时，所依据的预设平均音量。Then this average receiving volume is averaged with the preset average speaking volume originally stored in thestorage unit 13, and the above-mentioned average value is stored in thestorage unit 13 to replace the original preset average volume, as the basis for the next call preset average volume for .

在较佳实施例中，手持式通讯装置为一手机。声音接收元件11为一麦克风(Microphone)。声音播放元件12为一听筒(Receiver)；或者，当使用者将手持式通讯装置以扩音模式(或免持模式)使用时，声音播放元件12为一扬声器(Speaker)。In a preferred embodiment, the handheld communication device is a mobile phone. Thesound receiving element 11 is a microphone (Microphone). Thesound playing component 12 is a receiver; or, when the user uses the handheld communication device in amplified mode (or hands-free mode), thesound playing component 12 is a speaker.

请参照图2，其为本发明音量管理方法的作用流程图。本发明音量管理方法适用于一手持式通讯装置(例如：手机)，此手持式通讯装置于通话过程中接收一输入声音信号并产生一输出声音信号。并且，手持式通讯装置内储存有一预设平均音量，音量管理方法包括下列步骤：Please refer to FIG. 2 , which is a flow chart of the volume management method of the present invention. The volume management method of the present invention is applicable to a handheld communication device (such as a mobile phone). The handheld communication device receives an input audio signal and generates an output audio signal during a call. Moreover, a preset average volume is stored in the handheld communication device, and the volume management method includes the following steps:

开始通话(S20)后，手持式通讯装置每隔一特定时间会取得一输入声音信号，并分析输入声音信号以取得一接收音量；(S21)，其中此输入声音信号由声音接收元件11所接收。After starting the call (S20), the handheld communication device will obtain an input sound signal every specific time, and analyze the input sound signal to obtain a receiving volume; (S21), wherein the input sound signal is received by thesound receiving element 11 .

接着，比较接收音量与预设平均音量，并依据上述两者的差异，调整输出声音信号的一输出音量。在本实施例中，先判断接收音量是否约等于预设平均音量(S22)。Then, compare the received volume with the preset average volume, and adjust an output volume of the output sound signal according to the difference between the two. In this embodiment, it is first judged whether the received volume is approximately equal to the preset average volume (S22).

若接收音量约等于预设平均音量时，则维持目前的输出音量(S23)。若接收音量不等于预设平均音量时，则接着判断接收音量是否大于预设平均音量(S24)。若接收音量大于预设平均音量时，则增加输出音量(S25)。若接收音量非大于预设平均音量时，即表示接收音量小于预设平均音量，此时则需降低输出音量(S26)。If the received volume is approximately equal to the preset average volume, the current output volume is maintained (S23). If the received volume is not equal to the preset average volume, then it is judged whether the received volume is greater than the preset average volume (S24). If the received volume is greater than the preset average volume, then increase the output volume (S25). If the received volume is not greater than the preset average volume, it means that the received volume is lower than the preset average volume, and the output volume needs to be reduced (S26).

当通话结束(S27)时，手持式通讯装置会平均每隔特定时间所取得的输入声音信号的该接收音量，以获得一平均接收音量，并将此平均接收音量与预设平均音量作平均(S28)。最后，储存上一步骤所求得的平均值取代原本的预设平均音量，以作为下一次通话时，所依据的预设平均说话音量(S29)。When the call ends (S27), the handheld communication device averages the received volume of the input sound signal obtained at specific time intervals to obtain an average received volume, and averages the average received volume with the preset average volume ( S28). Finally, the average value obtained in the previous step is stored to replace the original preset average volume as the preset average speaking volume for the next call (S29).

在较佳实施例中，本发明所揭露的音量管理系统及方法为一种适用于手机的常驻软件程序，可安装至手机的存储器或固件内。In a preferred embodiment, the volume management system and method disclosed in the present invention is a resident software program suitable for mobile phones, which can be installed into the memory or firmware of the mobile phone.

由于手机通常是一种个人化的产品，故应用本发明，且使用者使用手机一段时间后，本发明的技术就可求得使用者平常的平均说话音量(平均接收音量)，此即代表在一般环境(情况)下，使用者即以此平均说话音量说话。Because the mobile phone is usually a kind of personalized product, so apply the present invention, and after the user uses the mobile phone for a period of time, the technology of the present invention just can obtain the user's normal average speaking volume (average receiving volume), which means that in In general environment (situation), the user speaks at this average speaking volume.

若目前取样的说话音量(即系统的接收音量)与之前的平均接收音量几乎相同的话，则表示使用者以平常的状态说话，应处于一般环境中。此时，程序不需对声音播放元件的输出音量做任何的调整。If the currently sampled speaking volume (ie the receiving volume of the system) is almost the same as the previous average receiving volume, it means that the user is speaking in a normal state and should be in a normal environment. At this time, the program does not need to make any adjustments to the output volume of the sound playing component.

若目前取样的说话音量(即系统的接收音量)大于之前的平均音量的话，则可以推断目前使用者应处于一个吵杂的环境。此时，程序会增加声音播放元件的输出音量。If the currently sampled speaking volume (ie the receiving volume of the system) is greater than the previous average volume, it can be inferred that the current user should be in a noisy environment. At this time, the program will increase the output volume of the sound player component.

若目前取样的说话音量(即系统的接收音量)小于之前的平均音量的话，则可以推断目前使用者可能处于很安静的环境下，或不希望别人听到声音播放元件所传出的声音。此时，程序会降低声音播放元件的输出音量。If the current sampled speaking volume (that is, the receiving volume of the system) is lower than the previous average volume, it can be deduced that the current user may be in a very quiet environment, or does not want others to hear the sound from the sound playback component. At this time, the program will reduce the output volume of the sound playback component.

值得注意的是，本发明所增加/降低声音播放元件的输出音量有范围限制，且会维持在使用者听觉上舒适的范围内。如此一来，不论在任何环境下，使用者所听到的通话音量就是调整过且适当的通话音量，同时使用者亦会依据声音播放元件的输出音量大小(听的清晰度)，而调整自己说话音量的大小，而不影响到其它人。It should be noted that the range of increasing/decreasing the output volume of the sound playing component in the present invention is limited, and will be maintained within the range that is comfortable for the user to hear. In this way, no matter in any environment, the call volume heard by the user is the adjusted and appropriate call volume, and the user will also adjust himself according to the output volume (listening clarity) of the sound playback component. Speak loudly without disturbing other people.

综上所述，本发明的音量管理系统及方法具有下列优点：In summary, the volume management system and method of the present invention have the following advantages:

一、依据使用者目前的说话音量(即系统的接收音量)，在通话过程中自动调整听筒或扬声器的输出音量，让使用者能享有良好的通话质量及舒适的通话经验。1. According to the user's current speaking volume (that is, the receiving volume of the system), the output volume of the earpiece or speaker is automatically adjusted during the call, so that the user can enjoy good call quality and comfortable call experience.

二、与已知技术相较，本发明所测量的并非是环境的噪音，而是使用者的说话音量。2. Compared with the known technology, what the present invention measures is not the noise of the environment, but the volume of the user's speech.

故，本发明不需有内建的分贝器，更不需另外过滤掉使用者的说话声。而是通过检测最接近麦克风的使用者声音，作为听筒或扬声器的输出音量的调整依据。Therefore, the present invention does not need a built-in decibel device, and does not need to additionally filter out the user's voice. Instead, the user's voice closest to the microphone is detected as a basis for adjusting the output volume of the earpiece or the speaker.

三、本发明会平均与记录使用者每次的说话音量(即系统的接收音量)，借此依照不同使用者的说话习惯及所处环境，做听筒输出音量调整的基准。3. The present invention averages and records the volume of the user's speech each time (that is, the receiving volume of the system), so as to serve as a benchmark for adjusting the output volume of the earpiece according to the speaking habits and environments of different users.

本发明虽以较佳实例阐明如上，然而其并非用以限定本发明精神与发明实体仅止于上述实施例。对熟悉此项技术者，当可轻易了解并利用其它元件或方式来产生相同的功效。因此，在不脱离本发明的精神与范围内所作的修改，均应包含在权利要求书所限定的范围内。Although the present invention is described above with preferred examples, it is not intended to limit the spirit and entities of the present invention to the above-mentioned examples. Those skilled in the art can easily understand and use other elements or methods to produce the same effect. Therefore, modifications made without departing from the spirit and scope of the present invention should be included in the scope defined by the claims.
