【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。更多还原

【Abstract】 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.更多还原
