摘要
针对短距离无线通信提出一种新的音频发射方案,实现了通过USB采集计算机中的音频信号,并通过无线发射的USB音频发射系统。采用PCM2702和BH1417芯片完成USB音频信号的采集和立体声调频发射,并通过单片机实现发射频率的控制。该系统具有多频段立体声发射、高保真音频输出、携带灵活方便、可靠性强等优点。
A new audio transmission scheme for short-distance wireless communication is proposed. The audio transmitting system is realized by collecting audio signal through USB and wireless transmitting. PCM2702 and BH1417 are used to collect and transmit USB audio signals,and transmitting frequency is controlled by microcontroller. The portable system has controllable transmitting frequency, high-fidelity audio output and high reliability.
