Abstract:In daily life, we will find that the loudspeaker device is always cone-shaped, because the conical device has a good sound amplification effect. This article mainly explores the influence of the shape and size of the conical device on the loudness of the distant sound by establishing a theoretical model and using the finite difference method for numerical simulation. At the same time, the theoretical numerical simulation method is promoted, so that it can be widely used in more aspects.
