| 摘 要： | 本文采用边界值方法求解强声发生器加压室波动方程，构建强声发声器类比电路模型，仿真分析加压室出口频率响应特性；结果表明：高频范围内，强声发生器加压室将产生高次波，导致加压室出口频率响应失真；通过设计不同加压室出口位置与半径，可抑制加压室出口处频率响应失真。

| Abstract: | Boundary value method is been used to solve the wave equation of the air chamber, the analogy circular model of the strong noise device has been established, frequency response characteristic of the exit in the air chamber has been simulated and analyzed. It reveals that higher-order harmonic in air chamber causes the distortion of the frequency response of the exit in air chamber of the strong noise device in high frequency, and the distortion can be suppressed by suitable choices of the annulus widths and radii. |

| Keywords: | Air chamber Wave equation Boundary value method higher-order harmonic frequency response characteristic |
