继续参见图13所示，检测传感器30还可以包括有数据处理单元34(Active FrontEnd，简称AFE)，接收装置33可以与数据处理单元34电连接，数据处理单元34可以与第一电路板31电连接，第一电路板31固定在柔性电路板50上，并与柔性电路板50电连接。接收装置33的电信号可以传输至数据处理单元34，数据处理单元34对其进行数据处理，转化成用于计算获得检测结果的数据信号(也即检测传感器30检测到的数据信号)，并将数据信号通过第一电路板31和柔性电路板50传输至耳机100的控制电路板40。Continue referring to FIG. 13 , thedetection sensor 30 can also include a data processing unit 34 (Active Front End, referred to as AFE), the receivingdevice 33 can be electrically connected to thedata processing unit 34, and thedata processing unit 34 can be electrically connected to thefirst circuit board 31. connection, thefirst circuit board 31 is fixed on theflexible circuit board 50 and electrically connected with theflexible circuit board 50 . The electrical signal of the receivingdevice 33 can be transmitted to thedata processing unit 34, and thedata processing unit 34 performs data processing on it, and converts it into a data signal (that is, the data signal detected by the detection sensor 30) for calculating and obtaining the detection result, and The data signal is transmitted to thecontrol circuit board 40 of theearphone 100 through thefirst circuit board 31 and theflexible circuit board 50 .

以通过耳机100实现心率检测为例，通过控制电路板40可以控制发射装置32发出检测光，如波段为500nm的绿光，检测光照射至耳朵300的皮肤(例如耳甲腔301的内表面)上，检测光透过皮肤组织后被血液反射，接收装置33接收反射的检测光将其转变为电信号，并将电信号传输至数据处理单元34，数据处理单元34对电信号进行数据处理，转化成用于实际计算心率的数据信号，并将该数据信号传输至控制电路板40。由于动脉中血液使流动的，对检测光的吸收与反射是变化的，接收装置33转变的电信号也是变化的，根据电信号的变化就能够反映血液流动的特点，实现对心率的检测。Taking heart rate detection through theearphone 100 as an example, thecontrol circuit board 40 can control theemission device 32 to emit detection light, such as green light with a wavelength band of 500nm, and the detection light is irradiated to the skin of the ear 300 (such as the inner surface of the concha cavity 301) Above, the detection light is reflected by the blood after passing through the skin tissue, the receivingdevice 33 receives the reflected detection light and converts it into an electrical signal, and transmits the electrical signal to thedata processing unit 34, and thedata processing unit 34 performs data processing on the electrical signal, It is converted into a data signal for actually calculating the heart rate, and the data signal is transmitted to thecontrol circuit board 40 . Because the blood in the artery is flowing, the absorption and reflection of the detection light is changed, and the electrical signal transformed by the receivingdevice 33 is also changed. According to the change of the electrical signal, the characteristics of the blood flow can be reflected to realize the detection of the heart rate.

以通过耳机100实现血氧饱和度检测为例，通过控制电路板40可以控制发射装置32发出检测光，例如分别发出波段为660nm的红光和波段为940nm的红外光，检测光照射至耳朵300的皮肤(例如耳甲腔301的内表面)上，检测光透过皮肤组织后被血液反射，接收装置33接收反射的检测光将其转变为电信号，并传输至数据处理单元34，数据处理单元34对电信号进行数据处理，转化成用于计算血氧饱和度的数据信号，并将该数据信号传输至控制电路板40。由于血液中氧和血红蛋白对660nm的红光吸收较少，而对940nm的红外光吸收较多，那么根据发出的检测光为660nm时形成的数据信号，与检测光为660nm时形成的数据信号之间的对比即可获得血红蛋白的氧合程度，实现对血氧饱和度的检测。Taking blood oxygen saturation detection through theearphone 100 as an example, theemission device 32 can be controlled to emit detection light through thecontrol circuit board 40, for example, red light with a wavelength of 660nm and infrared light with a wavelength of 940nm are respectively emitted, and the detection light is irradiated to theear 300 On the skin (such as the inner surface of the concha cavity 301), the detection light is reflected by the blood after passing through the skin tissue, and the receivingdevice 33 receives the reflected detection light and converts it into an electrical signal, and transmits it to thedata processing unit 34, and the data processing Theunit 34 performs data processing on the electrical signal, converts it into a data signal for calculating blood oxygen saturation, and transmits the data signal to thecontrol circuit board 40 . Oxygen and hemoglobin in the blood absorb less red light at 660nm, but absorb more infrared light at 940nm, so the difference between the data signal formed when the detected light is 660nm and the data signal formed when the detected light is 660nm The comparison between them can obtain the degree of oxygenation of hemoglobin, and realize the detection of blood oxygen saturation.
