The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

The heart rate detection system acquires a low-frequency sound signal of the object to be detected through a microphone or a speaker in a closed field formed by the body of the object to be detected; wherein the low-frequency sound signal includes the heart rate signal of the object to be detected.
具体的，上述待检测对象可以为任一具有心率和脉搏的生物，例如：人、狗、猫等。由于上述待检测对象的脉搏所形成的信号属于低频声音信号范围，且脉搏与心率一一对应，因此，当上述心率检测系统需要检测待检测对象的心率时，上述心率检测系统可以在待检测对象的身体所形成的封闭场下，先通过其上设置麦克风或扬声器获取到携带有待检测对象的脉搏信号的低频声音信号，即携带有待检测对象的心率信号的低频声音信号。其中，这里所说的麦克风或扬声器可以为上述心率检测系统本身所固有的麦克风或扬声器获，还可以为与上述心率检测系统连接的外设上固有的麦克风或扬声器(例如：与心率检测系统连接的耳机上的麦克风或扬声器)。Specifically, the above-mentioned object to be detected may be any creature with a heart rate and a pulse, such as a human, a dog, a cat, and the like. Since the signal formed by the pulse of the object to be detected belongs to the range of low-frequency sound signals, and the pulse corresponds to the heart rate one-to-one, when the heart rate detection system needs to detect the heart rate of the object to be detected, the heart rate detection system can detect the object to be detected. In the closed field formed by the body, first obtain the low-frequency sound signal carrying the pulse signal of the object to be detected, that is, the low-frequency sound signal carrying the heart rate signal of the object to be detected, through the microphone or speaker set on it. Wherein, the microphone or speaker mentioned here can be the microphone or speaker inherent in the above-mentioned heart rate detection system itself, or it can be the inherent microphone or speaker on the peripheral device connected with the above-mentioned heart rate detection system (for example: connected with the heart rate detection system microphone or speaker on the headset).
上述心率检测系统所获取到的待检测对象的低频声音信号，可以为在心率检测系统与待检测对象的身体形成的封闭场(即心率检测系统与待检测对象的身体构成的封闭空间)下，所获取到的待检测对象的低频声音信号，例如：在心率检测系统包覆待检测对象的外耳道时，此时，心率检测系统与待检测对象的耳朵构成一封闭空间(即封闭场)，在该封闭场下，心率检测系统可以通过麦克风或扬声器在待检测对象的耳朵内获取到待检测对象的低频声音信号；还可以为待检测对象的身体处于封闭场(即待检测对象的身体本身就位于封闭空间)时，心率检测系统通过麦克风或扬声器所获取到的待检测对象的低频声音信号。The low-frequency sound signal of the object to be detected obtained by the above-mentioned heart rate detection system may be in the closed field formed by the heart rate detection system and the body of the object to be detected (that is, the closed space formed by the heart rate detection system and the body of the object to be detected), The acquired low-frequency sound signal of the object to be detected, for example: when the heart rate detection system covers the external auditory canal of the object to be detected, at this time, the heart rate detection system and the ear of the object to be detected form a closed space (that is, a closed field). In this closed field, the heart rate detection system can obtain the low-frequency sound signal of the object to be detected in the ear of the object to be detected through a microphone or a speaker; it can also be that the body of the object to be detected is in a closed field (that is, the body of the object to be detected itself is When located in a closed space), the heart rate detection system obtains the low-frequency sound signal of the object to be detected through the microphone or the speaker.
需要说明的是，当上述心率检测系统在待检测对象的身体所形成的封闭场下，通过扬声器获取待检测对象的低频声音信号时，上述待检测对象所产生的低频声音可以使扬声器的振动系统(例如：膜片)产生振动，从而使得扬声器的磁回路系统(例如：磁铁)可以将该振动转换成电流或电压的形式的波形(该电压或电流形式的波形即为低频声音信号)，进而使得心率检测系统通过与扬声器连接的功放电路的反馈回路获取到该低频声音信号。可选的，当上述扬声器为心率检测系统的本身固有的扬声器时，上述与扬声器连接的功放电路可以为心率检测系统本身固有的功放电路，当上述扬声器为与心率检测系统连接的外设上的扬声器时，上述与扬声器连接的功放电路可以为与心率检测系统连接的外设上固有的功放电路。It should be noted that when the above-mentioned heart rate detection system obtains the low-frequency sound signal of the object to be detected through the speaker under the closed field formed by the body of the object to be detected, the low-frequency sound generated by the object to be detected can make the vibration system of the speaker. (for example: diaphragm) generates vibration, so that the magnetic circuit system of the speaker (for example: magnet) can convert the vibration into a waveform in the form of current or voltage (the waveform in the form of voltage or current is a low-frequency sound signal), and then The heart rate detection system obtains the low-frequency sound signal through the feedback loop of the power amplifier circuit connected with the speaker. Optionally, when the above-mentioned speaker is an inherent speaker of the heart rate detection system, the above-mentioned power amplifier circuit connected to the speaker may be an inherent power amplifier circuit of the heart rate detection system, and when the above-mentioned speaker is a peripheral device connected to the heart rate detection system. In the case of a speaker, the above-mentioned power amplifier circuit connected to the speaker may be an inherent power amplifier circuit on the peripheral device connected to the heart rate detection system.
S102、心率检测系统根据低频声音信号获取心率信号。S102, the heart rate detection system acquires the heart rate signal according to the low-frequency sound signal.
具体的，上述心率检测系统所获取到的低频声音信号中除了待检测对象的心率信号，还包括了其他低频声音信号，例如：待检测对象的骨骼运动所形成的声音信号、外界环境的噪声所形成的声音信号等，由于这些其他低频声音信号所对应的参数(例如：频率范围、幅值等)与标准心率信号所对应的参数不同，因此，上述心率检测系统在获取到待检测对象的低频声音信号之后，可以根据标准心率信号所对应的参数，在低频声音信号中获取心率信号。Specifically, in addition to the heart rate signal of the object to be detected, the low-frequency sound signal obtained by the above-mentioned heart rate detection system also includes other low-frequency sound signals, such as sound signals formed by the skeletal movement of the object to be detected, and noises of the external environment. Since the parameters corresponding to these other low-frequency sound signals (such as frequency range, amplitude, etc.) are different from the parameters corresponding to the standard heart rate signal, the above-mentioned heart rate detection system obtains the low frequency of the object to be detected. After the sound signal, the heart rate signal can be obtained from the low-frequency sound signal according to the parameters corresponding to the standard heart rate signal.
可选的，上述心率检测系统可以根据标准心率信号对应的频率范围，通过与该频率范围对应的带通滤波器，在低频声音信号中滤出位于该频率范围内的声音信号，该声音信号即为心率信号。可选的，上述心率检测系统还可以根据标准心率信号的声音等级，确定该标准心率信号的幅值，进而根据该幅值，将低频声音信号中满足该幅值的声音信号作为心率信号。可选的，若上述心率检测系统为可穿戴设备时，则可穿戴设备还可以将所获取到的低频声音信号发送给与可穿戴设备关联的移动终端，以使得该终端可以从该低频声音信号中获取到心率信号，并返回给可穿戴设备。Optionally, the above-mentioned heart rate detection system can filter out the sound signal located in the frequency range in the low-frequency sound signal through the band-pass filter corresponding to the frequency range according to the frequency range corresponding to the standard heart rate signal, and the sound signal is is the heart rate signal. Optionally, the above-mentioned heart rate detection system may also determine the amplitude of the standard heart rate signal according to the sound level of the standard heart rate signal, and then, according to the amplitude, use the sound signal satisfying the amplitude among the low-frequency sound signals as the heart rate signal. Optionally, if the above-mentioned heart rate detection system is a wearable device, the wearable device can also send the acquired low-frequency sound signal to a mobile terminal associated with the wearable device, so that the terminal can read the low-frequency sound signal from the wearable device. The heart rate signal is obtained in and returned to the wearable device.
S103、心率检测系统根据心率信号的波形，确定待检测对象的心率值。S103, the heart rate detection system determines the heart rate value of the object to be detected according to the waveform of the heart rate signal.
具体的，在上述心率检测系统在获取到待检测对象的心率信号之后，就可以根据该心率信号的波形，确定待检测对象的心率值。例如：上述心率检测系统可以根据心率信号的波形，确定心率信号的峰值在预设时间段内出现的次数，该次数即为待检测对象的心率值。其中，该预设时间段可以根据待检测对象的需求设定，例如：可以为一分钟，半分钟等。Specifically, after the above-mentioned heart rate detection system acquires the heart rate signal of the object to be detected, the heart rate value of the object to be detected can be determined according to the waveform of the heart rate signal. For example, the above heart rate detection system can determine the number of times the peak value of the heart rate signal occurs within a preset time period according to the waveform of the heart rate signal, and the number of times is the heart rate value of the object to be detected. The preset time period can be set according to the requirements of the object to be detected, for example, it can be one minute, half a minute, and the like.
现有技术中，可穿戴设备上专门设置有用于检测心率的红外发射器和光电传感器，以使得可穿戴设备可以通过这两个装置获取待检测对象的心率信号，进而使得可穿戴设备可以通过该心率信号，确定待检测对象的心率。然而，由于红外发射器和光电传感器的成本较高，使得现有的可穿戴设备在通过上述方式实现心率检测时，其成本较高。而本发明实施例提供的心率检测方法，当心率检测系统为可穿戴设备时，不用在该可穿戴设备上设置专门用于检测心率的装置，而是直接通过可穿戴设备本身所固有的麦克风或扬声器，或者，与可穿戴设备连接的外设上所固有的麦克风或扬声器，就可以在待检测对象的身体所形成的封闭场下，获取到携带有待检测对象的心率信号的低频声音信号，进而使得可穿戴设备可以通过该低频声音信号，获取到与待检测对象的心率对应的心率信号，从而通过该心率信号的波形，确定待检测对象的心率值。因此，本发明实施例提供的心率检测方法，在使可穿戴设备实现心率检测的情况下，可以降低可穿戴设备的成本。In the prior art, the wearable device is specially provided with an infrared transmitter and a photoelectric sensor for detecting heart rate, so that the wearable device can obtain the heart rate signal of the object to be detected through these two devices, so that the wearable device can use the two devices to obtain the heart rate signal of the object to be detected. Heart rate signal, to determine the heart rate of the object to be detected. However, due to the high cost of infrared transmitters and photoelectric sensors, the existing wearable devices have high costs when implementing heart rate detection through the above methods. However, in the heart rate detection method provided by the embodiment of the present invention, when the heart rate detection system is a wearable device, there is no need to set a device dedicated to detecting heart rate on the wearable device, but directly through the microphone or the wearable device itself. The speaker, or the inherent microphone or speaker on the peripheral connected to the wearable device, can obtain the low-frequency sound signal carrying the heart rate signal of the object to be detected under the closed field formed by the body of the object to be detected, and then The wearable device can obtain the heart rate signal corresponding to the heart rate of the object to be detected through the low-frequency sound signal, so as to determine the heart rate value of the object to be detected through the waveform of the heart rate signal. Therefore, the heart rate detection method provided by the embodiments of the present invention can reduce the cost of the wearable device under the condition that the wearable device realizes the heart rate detection.

In this embodiment, the heart rate detection system is taken as the earphone 1 (that is, the wearable device) as an example, and the second embodiment involves the
S201、耳机1在待检测对象的身体所形成的封闭场下，通过麦克风或扬声器获取待检测对象的低频声音信号。S201 , the
具体的，如图3所示，上述耳机1在包覆待检测对象的外耳道时，耳机1与待检测对象的外耳道形成了封闭空间，使得耳机1与待检测对象的耳朵形成了封闭场，这样，耳机1通过其上设置的麦克风或扬声器，可以获取到待检测对象的耳朵内的低频声音信号，通过这种方式，可以进一步减少所获取的低频声音信号中环境噪声的成分。Specifically, as shown in FIG. 3 , when the
需要说明的是，这里所说的麦克风可以为耳机1上的扬声器内部固有的降噪麦克风，还可以为耳机1上单独设置的麦克风，该麦克风的位置可以与扬声器的位置接近，这样，当耳机1包覆待检测对象的外耳道时，耳机1的麦克风和扬声器均可以处于耳机1与待检测对象的耳朵形成的封闭场内，从而使得耳机1可以通过该麦克风或扬声器获取到待检测对象的低频声音信号。It should be noted that the microphone mentioned here can be a noise-cancelling microphone inherent in the speaker on the
S202、耳机1根据标准心率信号的声音等级确定标准心率信号的幅值。S202, the
具体的，上述幅值可以为电压，也可以为电流，具体实施时可以根据用户的需求确定。当耳机1获取到待检测对象的低频声音信号之后，就可以根据标准心率信号的声音等级，以及现有的声音等级与幅值(即电压或电流)的对应关系，确定标准心率信号的幅值。其中，这里所说的标准心率信号的声音等级可以为正常心率信号的声音等级，该正常心率信号的声音等级可以根据具体的待检测对象确定，例如该正常心率信号的声音等级可以在40分贝至60分贝之间。上述标准心率信号的声音等级，还可以为一大于低频声音信号中除心率信号之外的其他声音信号对应的声音等级的声音等级，在这种情况下，该标准心率信号的声音等级具体可以根据低频声音信号所包括的声音信号进行确定。上述标准心率信号的声音等级具体可以根据用户的需求或者待检测对象的实际情况确定，本发明对此不作限定。Specifically, the above-mentioned amplitude may be a voltage or a current, and may be determined according to the needs of the user during the specific implementation.
