2) acoustical hotspot
声场聚焦
1.
This paper introduces the methods for acoustical hotspot generation using multiple sources,presents the hardware design of a multi-channel loudspeaker array system.
简述了声场聚焦的原理,给出了扬声器阵列系统设计的硬件实现,通过模块化设计,将模数/ 数模(ADC/DAC)转换部分做成独立的板卡,并通过 I~2S 接口协议与信号处理母板相连接,所有板卡共用同一个时钟信号以实现同步快拍采样。
