Abstract

The invention discloses an audio play system comprising an audio play device and an earphone used by the audio play device. The earphone comprises a variable resistor unit and a waveform generation unit, wherein the variable resistor unit is an elastic element; when the earphone is taken off or worn, the elastic element occurs elastic deformation and the resistance thereof changes along with the elastic deformation; and the waveform generation unit is used for generating a corresponding electric signal according to the change of the resistance of the variable resistor unit. The audio play system judges whether the earphone is in a using state according to the corresponding electric signal, and controls the working state of the audio play device according to the using state of the earphone. Therefore, the on, off or pause state of the audio play device can be controlled automatically.

Description

technical field [0001] The invention relates to an audio playback system and an earphone applied thereto, in particular to an audio playback system which automatically controls the playback function and an earphone applied thereto. Background technique [0002] Sound playback devices such as radios, MP3 players, and CD players can output sound through earphones, wherein a control switch is set on the wire-controlled earphone to control the sound playback devices, making it more convenient for users to control. When the wire-controlled earphone is removed from the head by the user, the sound playback device is still in working condition, and the user needs to manually operate the wire-controlled switch on the earphone to control the sound playback device, which is not easy to operate. Contents of the invention [0003] In view of this, it is necessary to provide an audio playback system, which detects the electrical signal generated when the earphone is taken off or put on,...
