摘要
提出了同时优化扬声器阵列的指向性和声功率级的方法。运用该方法可以优化扬声器阵列的输入电压分布,获得指向性和声功率级二者兼顾的扬声器阵列。本方法不必使用复杂的与频率相关的信号处理装置。模拟结果和实验测量结果表明该方法是可行的和有效的。
In this article, a method to optimize not only the directivity but also the acoustic power of loudspeaker arrays is developed. In consideration of the directivity and acoustic power, the input voltage distribution of a loudspeaker array can be optimized and selected. Frequency-dependent signal processors are not needed with this method. The results of computer simulation and experiment both show that the method is feasible.
