Description

Audio switching method, device, terminal, earphone and storage medium

Technical field

The present invention relates to the field of communications, and in particular to an audio switching method and apparatus, a terminal, an earphone, and a storage medium.

Background technique

At present, the digital audio of intelligent terminals on the market has risen, and the 3.5mm headphone jack has a promising future. In addition, from the perspective of space saving and waterproof, the Type-c interface replaces the 3.5mm interface, just around the corner. Smart terminal audio contains a lot of scenes, which are mainly talking, talking, playing and recording. Whether it is in a call, play or recording, the data transmitted through the 3.5mm headphone is an analog signal; if digital audio is implemented, the Type-c interface needs to be taken.

Due to delay and power consumption, related technologies cannot realize that the call, play and recording are digital transmission methods. The solution is that the playback mode is digital mode, and the call and recording are mixed modes of the analog mode; although the analog-digital hybrid method can avoid the problem of call delay and power consumption, but introduces a new problem, the headphone interface cannot be defined according to the Type-c pin. , resulting in headphones that are not versatile.

Specifically, in the related art, the analog-to-digital mixing method, the call is in an analog format, and the playback is in a digital format; the D+/- of the mobile phone side is connected together; the digital and analog data are taken in the same physical channel. The B6/7 on the earphone side is the NA pin; it supports forward and reverse switching. To some extent, it solves the short board with large call delay and increased power consumption; but from playback to call or from call to play, the USB device re-initiation enumeration process is required, and the enumeration process is repeated twice, and the delay is increased. And the headset can only be used with a specific phone to complete the call function. Headphones are not versatile and the user's physical examination is poor.

In view of the above technical problems in the related art, an effective solution has not yet been proposed.
