Abstract

The invention discloses an audio output circuit and an earphone. The audio output circuit comprises a first earpiece, a second earpiece and an audio module, wherein the audio module is arranged to output a stereo audio signal to the first earpiece and the second when the earpiece and the second earpiece are normal, and output a mono audio signal to the second earpiece or the first earpiece in thenormal playing state when the first earpiece or the second earpiece is abnormal.

Description

technical field [0001] The invention relates to the technical field of circuit design, and more specifically, the invention relates to an audio output circuit and an earphone. Background technique [0002] Existing stereo earphones, different from mono earphones, have two earpieces, which require both ears to be worn, and two loudspeakers, which are respectively arranged in the left earpiece and the right earphone, and the left and right channels realize the stereo effect, and are widely used in For sports, listening to music, making phone calls, etc., it is more widely used than mono earphones. [0003] Stereo headphones are divided into two types: earplugs and head-mounted, both of which have the difference between the left and right channels, and cannot be used interchangeably, otherwise it will directly affect the fidelity of the sound source and the resolution of the frequency of the sound source. [0004] When an earpiece of the stereo earphone fails to produce sound,...
