Problems solved by technology

Traditional music players basically have basic functions such as reading SD card, reading U disk (USB interface), USB Audio, HID, AUX and radio, but most of these traditional music players do not have integrated Bluetooth function, so there is no way to communicate with them. External Bluetooth device communication, it becomes difficult to turn the traditional music player into a music player with Bluetooth function

Abstract

The invention provides a bluetooth audio adapter and an audio player. The bluetooth audio adapter comprises a bluetooth base band circuit and a main controller. The main controller comprises an HCI (host controller interface), a bluetooth protocol processing unit, a DSP (digital signal processor), an audio controller and a USB (universal serial bus) controller which are connected sequentially. The HCI is connected with an HCI of the bluetooth base band circuit. The USB controller is connected with a USB interface of a music player through the USB interface. With the bluetooth audio adapter and the audio player, limitation of traditional music players with USB control circuits is overcome, the traditional music players can be used as the bluetooth music players, communication between the traditional music players with the USB control circuits and other bluetooth wireless devices is realized, and market application value is remarkable.

Description

technical field [0001] The invention relates to the technical fields of bluetooth and audio, in particular to a bluetooth audio adapter and an audio playback device. Background technique [0002] Bluetooth (Bluetooth) is a short-range wireless communication standard jointly developed by mobile communication companies and mobile computing companies. wireless link. The frequency band specified by the specification is the public ISM frequency band, and the maximum data rate can reach 1Mbps. [0003] With the development of wireless technology and the improvement of people's living standards, some consumer electronic devices are equipped with Bluetooth devices. Taking the Bluetooth music player as an example, the Bluetooth music player adds the Bluetooth communication function on the basis of the ordinary music player, so that the music player can communicate with other Bluetooth peripherals through the Bluetooth protocol, thereby realizing wireless music playback and wireless...
