Earphone

Abstract

The invention provides an earphone. The earphone comprises an earphone interface, a control module, an audio coder decoder, a power amplifier module, a speaker module and a proximity sensor, wherein the earphone interface is used for connecting an electronic device, the control module and the audio coder decoder are electrically connected with the earphone interface, the power amplifier module iselectrically connected with the control module and the audio coder decoder, the speaker module is electrically connected with the power amplifier module, and the proximity sensor is electrically connected with the control module; the proximity sensor is arranged at an ear plug of the speaker module and is used for detecting whether a human body approaches the ear plug of the speaker module and transmitting a detected human body approaching signal to the control module; the control module is used for opening the power amplifier module when the human body approaching signal indicates a human body to approach the ear plug of the speaker module, and controlling progressive increase of the amplification ratio of the power amplifier module according to a preset step length. According to the technical scheme of the invention, the earphone can automatically identify whether a user wears the earphones, and can control the play volume of the earphones to progressively increase to the current play volume of the electronic device after identifying that the user wears the earphones.
