USB (Universal Serial Bus)-based wireless sound box device

Abstract

The invention provides a USB (Universal Serial Bus)-based wireless sound box device, which is used for connecting an adapter with a USB interface so as to play back a sound source data stream transmitted by the adapter. The USB-based wireless sound box device comprises a USB interface module, a USB main equipment driving module, a decoding module and an audio playback module, wherein the USB interface module is used for connecting the adapter; the USB main equipment driving module is used for recognizing the type of the adapter connected with the USB interface module, loading a main equipment driver matched with the type of the adapter according to the recognized type of the adapter and configuring a system into a data receiving state; the decoding module is used for reading the sound source data stream transmitted through the adapter; and the audio playback module is used for receiving and playing back the decoded audio data stream. According to the invention, a completely uniform wireless sound box device with USB main equipment as an interface is adopted to realize the playback of various different sound sources on a same sound box in different wireless manners, so that the purpose of realizing the data exchanging and sharing for users in different system environments and different application manners is achieved, and thus, great convenience is brought to the users.
