文中详细分析了可控指向性阵列扬声器的工作原理及特性,特别是通过DSP和功放控制声瓣的传播方向,避免建筑结构的反射声能,从而达到控制指向性的功能。
In this paper, the working principle and characteristics of the controllably directional array loudspeaker are analyzed in detail. In particular, the direction of propagation of the acoustic valve is controlled by the DSP and the power amplifier to avoid the reflected acoustic energy of the building structure so as to achieve the function of controlling the directivity.
