Abstract

The invention discloses an audio compatible circuit, an earphone and an electronic system. The audio compatible circuit comprises a first microphone, a second microphone and a control circuit, wherein the control circuit controls the first microphone to work and the second microphone not to work when the earphone with the audio compatible circuit is connected with a mobile terminal with the support of a national standard earphone, and the control circuit controls the first microphone not to work and the second microphone to work when the earphone with the audio compatible circuit is connected with a mobile terminal with the support of an American standard earphone.

Description

technical field [0001] The invention relates to the technical field of audio compatibility, in particular to an audio compatible circuit, an earphone and an electronic system. Background technique [0002] The current earphone jacks of mobile terminals generally have two specifications, one is a jack that supports national standard earphones, and the other is a jack that supports American standard earphones. When the earphone jack of the mobile terminal is a jack that supports national standard earphones, if an American standard earphone is connected to it, there will be problems such as no sound or low volume of the earphone; on the contrary, when the earphone jack of the mobile terminal is a jack that supports American standard earphones , if the national standard headset is connected to it, similar problems will occur. [0003] Therefore, the field expects an earphone that can work normally when it is connected to the mobile terminal no matter whether the earphone jack o...
