Wireless and wired compatible earphone system, earphone playing method and true wireless earphone

Abstract

The invention relates to a wireless and wired compatible earphone system . The earphone system comprises a micro-control unit, a memory module, an audio decoding power amplifier module, a sound production module and a switch element, and the output end of the switch element is connected with a wireless communication module or an I / O (Input / Output) interface so as to switch the connection between the micro-control unit and the wireless communication module or the connection between the micro-control unit and the I / O interface. Coexistence of a wired system and a wireless system of the earphoneis realized through the switch element, thereby facilitating use of a user. According to the earphone system, the audio decoding power amplifier module and the memory module are adopted, so that the earphone has a function of locally playing an audio file, the distortion degree of the audio file played by the earphone is small by processing an audio signal through the audio decoding power amplifier module, and the tone quality played by the sound production module is better; as the audio decoding power amplifier is compatible with mainstream lossless files with high code rate in the mode, theaudio decoding power amplifier has a low distortion effect on audio transmission of a wired system, the sound quality loss of sound emitted by the sound production module of the earphone is small, andthe sound quality is good.

Description

technical field [0001] The present invention relates to the technical field of earphones, in particular to a wireless and wired earphone system, and based on the system, an earphone playback method and a dual-system true wireless earphone are provided. Background technique [0002] Earphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears. [0003] Earphones are also the development from wired earphones to wireless earphones, and wireless earphones are the middle line replaced by radio waves, which are connected from the audio outlet of the computer to the transmitter, and then sent from the transmitter to the earphones of the receiver through radio waves. The receiver is quite So a radio; there are three types of wireless headsets: one is a Bluetooth headset, the other is an infrared headset, and the third is 2.4G. [0004] With the development of compu...

Problems solved by technology

[0004] With the development of computer technology, there are wireless earphones and wired earphones on the market, and the wireless earphones and wired earphones are used separately; the above-mentioned wireless earphones need to rely on Bluetooth protocol, wifi protocol, etc. to transmit signals and communicate with Bluetooth or WiFi music equipment ( Such as mobile phone, PC terminal) connection, due to the influence of transmission protocol, format, etc., the sound quality of the wireless headset is highly distorted and the details are lost, resulting in poor sound quality; and wired headsets connected by cables will cause high distortion transmission and cause headset playback the sound quality is poor
