Abstract

The invention belongs to the field of control systems, and specifically relates to a multi-segment earphone self-adaptive switching system, method and device, aiming to solve the problem that the existing earphone system cannot be compatible with 4-segment / 3-segment earphones, and cannot support 3-segment passive MIC at the same time Type of audio peripherals, and does not support forward and reverse transmission and the problem of low integration. The invention includes: a forward transmission subsystem and a reverse transmission subsystem with the same connection mode, and the forward / reverse transmission subsystem is switched only by changing the input and output interfaces. In the forward transmission subsystem, the analog audio signal is input to the 4-segment audio socket, and the digital audio signal is input to the I2S audio socket, which is transmitted to the audio encoding / decoding module through the analog switch array for mixing or alternatively, and then transmitted to the analog switch array It is then transmitted to a 3-segment audio deck or a two-channel balanced audio deck output. The invention realizes the multi-channel output and forward and reverse switching of the earphone, and improves the integrability of the earphone system.

Description

technical field

[0001] The invention belongs to the field of control systems, and in particular relates to a multi-segment earphone self-adaptive switching system, method and equipment. Background technique

[0002] At present, there are many types of audio peripherals, and earphones are also divided into 3-segment and 4-segment (US / GB). The audio system is particularly important for judging the type of earphones connected. Poor matching will lead to low sound or only tune but no sound, etc. Phenomenon; at the same time, the audio signal from input to final output usually requires pre-conditioning, link switching, forward and reverse transmission and other related processes. At present, although there are corresponding product designs for each link, there are very few portable and easy-to-integrate products that integrate the entire audio pre-stage process. The functions of the existing audio pre-processing units are relatively simple. Most of them only do simple multi-segm...
