Abstract

The invention discloses an earphone interface circuit and a terminal. The earphone interface circuit comprises a first interface module used for being electrically connected with a microphone plug of the earphone; and a second interface module, used for being electrically connected with an audio output plug of the earphone or an integrated plug of the earphone. According to the embodiment of the invention, the interface requirement of a double-3pin earphone can be met, and the interface requirement of a single-4pin earphone can also be met, so that the applicability of a product is improved, and the use cost of a user is reduced.

Description

technical field [0001] The invention relates to the technical field of earphone interface, in particular to an earphone interface circuit and a terminal. Background technique [0002] At present, there are two types of 3.5mm earphones, one is a single 4pin earphone, and the other is a double 3pin earphone. Wherein, the single 4pin earphone is an earphone including an integrated plug, and the integrated plug has both a microphone function and an audio output function. The double 3pin earphone is an earphone including two plugs, one plug is used for microphone signal input, and the other plug is used for audio signal output. [0003] In the related art, the interface of most products is a single 4pin plug interface. If the user needs to access the earphone with double 3pin plugs, he needs to use a two-in-one converter to convert the interface. This method not only increases the user's use cost, but also affect the suitability of the product. Contents of the invention [0...
