Abstract

The invention provides a wireless audio adapter and an audio playing device. The wireless audio adapter comprises a wireless module, a master controller and an SD interface. The master controller comprises a wireless module interface, a protocol processing unit, an audio decoder, an audio coder, a file system simulator and an SD controller. The master controller is connected with the wireless module through the wireless module interface, the wireless module interface, the protocol processing unit, the audio decoder, the audio coder, the file system simulator and the SD controller are connected in sequence, the file system simulator is further connected with the protocol processing unit, and the SD controller is connected with the audio playing device through the SD interface. The wireless audio adapter and the audio playing device overcome the limitations of a traditional music player with an SD interface and the traditional music player with an SD interface can be changed into a wireless music player.

Description

technical field [0001] The invention relates to the field of wireless and audio technology, in particular to a wireless audio adapter and an audio playback device. Background technique [0002] With the development of wireless technology and the improvement of people's living standards, many consumer electronic devices are now equipped with wireless devices. At the same time, music players have now spread to millions of households. Music players basically have basic functions such as reading SD card (Secure Digital Memory Card, secure digital card) and reading U disk (USB interface). However, traditional audio playback devices basically do not have wireless functions, so there is no way to communicate with external wireless devices. [0003] Therefore, how to change the traditional music player with SD interface into a music player with wireless function becomes an urgent problem to be solved. Contents of the invention [0004] Based on this, the present invention provi...
