作者提出了一种扩展喇叭低频响应的办法,如图1.图1(a)是原来的指数喇叭,图1(b)表示具有和(a)相同的蜿展指数和形状的喇叭;但切成较小的喇叭口,且在口上加一凸缘以恢复低频响应;图1(c)表示将(b)拉伸以恢复原来的长度,这样就降低了截止频率,因而扩展了低频响应。
The authors propose a way to extend the speaker’s bass response as shown in Figure 1. Figure 1 (a) is the original exponential speaker, and Figure 1 (b) shows the speaker with the same meandering index and shape as (a); however, Into a smaller bell mouth with a flange on the mouth to restore the bass response; Figure 1 (c) shows that stretching (b) to restore the original length reduces the cut-off frequency thereby extending the bass response.
