Music playing system based on wireless audio data transmission

Abstract

The invention discloses a music playing system based on wireless audio data transmission. The music playing system based on wireless audio data transmission comprises a sending end, a receiving end and a loudspeaker. A music player developed based on Android SDK (software development kit) and operated on a mobile terminal device serves as the sending end, an Android system supportive to the WiFi (wireless fidelity) function is installed on the mobile terminal, the music player defines a bottom decoding library to transmit decoded pulse modulation data through a WiFi network, and a smart phone or a tablet personal computer serves as the mobile terminal. The receiving end comprises a master control unit, a WiFi network unit and a digital-to-analog conversion output unit, a central control function is jointly completed by the master control unit and a peripheral storage device, and the WiFi network unit is connected to the master control unit by means of USB (universal serial bus) HOST. A WiFi network module receives audio data transmitted by the sending end by means of wireless network transmission and sends the audio data to a master control module. The digital-to-analog conversion output unit is used for digital-to-analog conversion of the audio data to complete audio receiving and playing while providing an output interface, and the loudspeaker is connected with the receiving end to directly output corresponding audio signals.
