摘要

定向声辐射将声音集中在特定方向,并减少其他方向的声辐射。本研究利用致动器阵列驱动的平板,通过声学对比度控制算法实现二维定向声辐射。根据面板的模态振动分析了较高频率下的混叠效应,并提出了一种估算高频极限的方法。对不同参数的激励器阵列进行了仿真,以验证所提方法的有效性,并将声学对比响应与传统扬声器阵列进行了比较。

Directional sound radiation from a rectangular panel and the high frequency limit.

Directional sound radiation focuses sound in a specific direction and reduces sound radiation in other directions. This study uses a flat panel driven by an actuator array to realize two-dimensional directional sound radiation by the acoustic contrast control algorithm. The aliasing effect at higher frequencies is analyzed based on the modal vibration of the panel, and a method for estimating the high frequency limit is proposed. Actuator arrays with different parameters are simulated to verify the efficacy of the proposed method and compare the acoustic contrast response with the conventional loudspeaker arrays.
