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.
