In the technical scheme provided by the invention, an earphone monomer 1 is provided with an ear inlet part 11 which is used for extending into an ear canal, an induction part 2 is arranged on the ear inlet part 11, the induction part 2 is used for monitoring electrocardiosignals of a heart by contacting with the skin of the ear canal, the induction part 2 is arranged on the earphone monomer 1, the induction part 2 is contacted with the skin of the ear canal when a user wears the earphone monomer 1, the wireless earphone component 1000 also comprises an earphone charging box 3, and a biological signal amplifier 40 is arranged on the earphone charging box 3; when testing electrocardiosignals, the earphone charging box 3 is held by one hand, and the electrode of the biological signal amplifier 40 of the earphone charging box 3 and the electrode of the induction part 2 form an electrocardiosignal testing path. In the technical scheme provided by the invention, the sensing part 2 and the biological amplifier 40 on the earphone charging box 3 are arranged on the earphone single body 1, so that a user can listen to the audio frequency of the wireless earphone and detect the heart health condition at the same time, and the wireless earphone component 1000 capable of monitoring the heart health of the user is provided.
Specifically, in order to enable the sensing unit 2 to perform sensing monitoring while being worn, in the present embodiment, the sensing unit 2 is disposed on the periphery of the ear insertion portion 11. So set up go into ear 11 and wear the card and hold in the duct while, go into the skin laminating in the perisporium and the duct of ear 11, can guarantee sensing part 2 can monitor in real time.
Specifically, in order to realize the monitoring of the heart health status, the sensing part 2 may be configured as a biosensor, an ECG sensor, or the like, and in this embodiment, the sensing part 2 includes an ECG sensor module. An ECG (Electrocardiogram), an abbreviation for electrocardiograph, is a device that measures the electrical activity of the heart. Each beat of the heart produces an electrical wave that contracts and transports blood to other parts of the body. The electrocardiogram is to measure the electric wave to know the health condition of the heart of the measurer. It does this by measuring the amount of point activity in the heart and the time between two heartbeats, so that it can be determined whether the heart is moving normally, slowly, rapidly or irregularly.
Because the ECG sensor is used for monitoring the health condition of the heart, the working principle of the ECG sensor is the principle of simulating a hospital to carry out electrocardiogram test, and the ECG sensor is a non-invasive test and reflects the potential heart condition by collecting millivolt (mV) level electric signals generated by the heart. The ECG signal can be detected at many parts of the body, but in the case where the distance between the positive and negative electrodes of the on ECG sensor is set to be relatively long, the monitored signal is stronger and the monitored data is more accurate.
Further, in order to make the monitored data more accurate, in this embodiment, the wireless headset assembly 1000 includes two headset units 1, one of the headset units 1 is used for the left ear, and the other is used for the right ear, the ECG sensor module includes a positive electrode ECG module 21 and a negative electrode ECG module 22, the positive electrode ECG module 21 is disposed at the ear entrance 11 of one of the two headset units 1, and the negative electrode ECG module 22 is disposed at the ear entrance 11 of the other of the two headset units 1. With this arrangement, the distance between the positive electrode ECG module 21 and the negative electrode ECG module 22 is longer, and the measured data is more accurate than the data measured by arranging the positive electrode ECG module 21 and the negative electrode ECG module 22 on the same earphone unit 1.
Specifically, in this embodiment, the wireless headset assembly includes a control module 30, the control module 30, i.e., a microprocessor, can complete operations such as obtaining an instruction, executing the instruction, and exchanging information with an external memory and a logic component, and is an operation control part of the intelligent wearable device, and the control module 30 is electrically connected to the sensing part 2 and is configured to control the monitoring of the sensing part 2.

The wireless headset assembly 1000 further has a power module 90 and a wearing detection module 80, and the control device 30 is electrically connected to the power module 90 and the wearing detection module 80 to supply power to the headset 100.
Furthermore, the electrical signals emitted by the electrocardiogram (electrocardiogram, such as a biosignal amplifier), electroencephalogram (electroencephalogram) or electromyogram circuit are very small, usually only a few microvolts (ten-thousandth of a volt). Since the patient's body also acts as an antenna and can be subject to electromagnetic interference, particularly 50/60Hz household supply noise, this interference can mask the biological signals, making them difficult to measure. Therefore, the right leg driving circuit can be added to eliminate the interference noise. Meanwhile, the signals collected by the positive electrode ECG module 21 and the negative electrode ECG module 22 have common mode noise, which is noise that a noise current leaked through a stray capacitance or the like returns to a power supply line via the ground. In order to filter out the Common mode noise, the wireless headset assembly 1000 further includes a bio-signal amplifier 40, the control module 30 is electrically connected to the bio-signal amplifier 40 and the sensing part 2, and the bio-signal amplifier 40 is configured to amplify the electrocardiographic signal monitored by the sensing part 2 and transmit the amplified electrocardiographic signal to the control module 30. The biological signal amplifier 40 is used for eliminating interference noise, i.e. the common mode noise, and the filtered and amplified electrocardiosignals are transmitted to the microprocessor, and useful signals including but not limited to p-wave, T-wave, QRS-complex and the like are extracted from the electrocardiosignals through an electrocardiosignal algorithm. Meanwhile, the baseline drift generated by poor contact of the measuring electrode, power frequency interference generated by power supply equipment, myoelectric interference caused by fine contraction and vibration of muscles and other noises are filtered by utilizing an algorithm.
Further, in order to enable the bio-signal amplifier 40 simulating the driving of the right leg to achieve the optimal monitoring operation state and also take the use state of the user into consideration, referring to fig. 2, in the present embodiment, the wireless headset assembly 1000 further includes a headset charging box 3, and the bio-signal amplifier 40 is disposed in the headset charging box 3.
