基于BC03蓝牙模组的无线有源音箱设计

给出了一种采用蓝牙模组的无线通信系统。将CSR的BC03蓝牙模组与TDA2030AOCL功放置于音箱中，通过C8051F020单片机UART0完成与蓝牙模组通信和控制，实现蓝牙手机或者PC电脑与BC03蓝牙模组的互连，完成HFP和A2DP功能，采用4×5键盘完成数据和音频控制指令的输入，并通过TS1602 LCD完成基本的数据和控制指令显示等。实验结果表明：本系统能够成功实现蓝牙手机或者PC设备与BC03蓝牙模组的互连，完成蓝牙模组的HFP和A2DP功能，音频最大输出功率可以达到14W（RL=4Ω），可以直接驱动4Ω或者8Ω的音箱负载。

Design of Wireless Active Sound Box Based on BC03 Bluetooth Modules

The wireless communication system with bluetooth modules is discussed. BC03 bluetooth modules of CSR and TDA2030A OCL power amplifier are placed in sound box. The interconnection of bluetooth mobile telephone or PC with bluetooth modules, and the function of HFP and A2DP are realized by means of the communication and control between bluetooth modules accomplished by UART0 of SCM （single chip mieyoco） C8051F020. The system adopts 4 × 5 keyboard to implement the input of data and audio frequency control instructions, which is displayed by TS1602 LCD. The experiment results show that the system can realize HFP and A2DP function of the bluetootb modules by interconnecting the bluetooth mobile telephone or PC with BC03 bluetooth modules. The maximum output power of audio frequency can reach 14 W （RL =4Ω）, and drive 4Ω or 8Ω load of sound box.
