Abstract
The utility model discloses an earphone socket and an earphone noise reduction device. The earphone socket comprises a detection switch which is arranged at the bottom of the earphone socket. When an earphone plug matched with the earphone socket is plugged into the earphone socket and the top of the earphone plug contacts with the detection switch, the detection switch sends a first signal to a control circuit of a power amplifier of audio equipment. When the earphone plug is unplugged from the earphone socket and the top of the earphone plug is separated from the detection switch, the detection switch sends a second signal to the control circuit of the power amplifier of the audio equipment. The control circuit controls the power amplifier of the audio equipment to turn from a mute state into an operating state when receiving the first signal, and controls the power amplifier of the audio equipment to turn from the operating state into the mute state when receiving the second signal. With the adoption of the technical scheme of the utility model, an emergence period of plosives during plugging and unplugging processes of the earphone is avoided, and the usage comfortableness is greatly improved for users.
