Abstract: Disclosed are a method and apparatus for improving a signal-to-noise ratio of a microphone signal. The method includes: selecting a target microphone to be improved as a first microphone, and selecting a microphone whose signal-to-noise ratio is greater than a signal-to-noise ratio of the first microphone and exceeds a preset first threshold as a second microphone; and adding, by an adder, a voice signal of the first microphone and a voice signal of the second microphone in a case that a same voice signal is inputted, to obtain a first microphone signal whose signal-to-noise ratio has been improved.

Abstract: A wireless headphone system, a wireless headphone, and a base. The wireless headphone system includes the wireless headphone and the base. The base includes a base RXD wire, a base TXD wire, a base connection wire, and a base triode; and the wireless headphone includes a wireless headphone RXD wire, a wireless headphone TXD wire, a wireless headphone connection wire, and a wireless headphone transistor. The base RXD wire and the base TXD wire are connected together through the base transistor and led out through the base connection wire. The wireless headphone RXD wire and the wireless headphone TXD wire are connected together through the wireless headphone transistor and led out through the wireless headphone connection wire. When the headphone is charged on the base, two-way communication between the headphone and the base can still be implemented while maintaining the existing three-wire design.
