| titleOfInvention | Wireless Headphones |
| abstract | The present application relates to a wireless headset, which includes a control device, a differential wiring circuit and a microphone; the microphone is connected to the control device through the differential wiring circuit. The differential wiring circuit includes a first differential signal line and a second differential signal line. The output end of the microphone is connected to the positive end input end of the microphone of the codec in the control device through the first differential signal line, and the ground end of the microphone passes through the second differential signal line. The differential signal line is connected with the microphone negative input end of the codec in the control device. When there is noise interference from the outside, the strong anti-interference ability of the differential wiring circuit can effectively suppress the propagation of noise, thereby ensuring that the earphones cannot hear the noise and improving the comfort of use. |
