Heart rate signal produces interference to supply voltage, and the first filtration module U3 can be to the first contact P1 cell voltage and modulation heart rate
Signal is filtered processing, so that the modulation heart rate signal of exchange can not be transmitted to supply voltage output end VCC1, prevents exchange
Adjustment heart rate signal to heart rate detection module U1 and modulation module U2 cause damage;Simultaneously so that what the first contact P1 was received
Cell voltage can be transmitted to supply voltage output end VCC1.Modulation heart rate signal will be sent to second by the first contact P1 and touch
Point P2, as the second heart rate signal.Because the second heart rate signal is also the AC signal of setpoint frequency, therefore the second filtration module
U5 can be filtered processing to the second contact P2 cell voltage and the second heart rate signal so that the second heart rate signal can not be passed
Cell voltage output end VCC2 is transported to, to prevent the second heart rate signal of exchange from causing to damage to battery;Simultaneously so that battery electricity
The cell voltage of pressure output end VCC2 outputs can be sent to the second contact P2.First filter circuit U3 and the second filter circuit U4
Can be low-pass filter circuit, so that the modulation heart rate signal and the second heart rate signal of setpoint frequency can be filtered out.Specifically, the
One filter circuit U3 and the second filter circuit U4 for example can be to be less than above-mentioned setpoint frequency by any one cut-off frequency
Low pass filter is provided.The effect of electric capacity C1, C2 stopping direct current is utilized simultaneously, prevents the cell voltage of direct current from causing modulation module
U2 and demodulation module U4 saturation, realize the separation between the cell voltage of direct current and the heart rate signal of exchange.Using electric capacity C1,
The effect of C2 logical exchange, modulation heart rate signal is transmitted to demodulation module U4.The solution obtained after demodulation module U4 demodulation process
Adjust heart rate signal should be identical with the frequency of the first heart rate signal.
So, the present invention makes for the connection circuit of separate type call bracelet by being multiplexed the first contact and the second contact
It can transmit cell voltage, and heart rate signal can be transmitted again, it is possible to realize separate type call bracelet in connection bluetooth earphone and
The reduction of the number of contacts of bracelet, can be effectively improved the outward appearance of separate type call bracelet.Separation call bracelet can also be improved
Water resistance.By embodiments of the invention, the reliability of the contact portion of bluetooth earphone and Intelligent bracelet can also be improved.
