[0002] The horn of a speaker refers to the acoustic device inside the speaker, which is used to control the propagation and diffusion of audio signals. The design of the horn can affect the sound quality, timbre and volume performance of the speaker. The shape of the horn can be divided into different types, and the common ones include circular, rectangular, parabolic, etc. Different shapes of horns will affect the propagation mode of audio signals, and thus affect the sound effect of the speaker. For example, a parabolic horn can focus and spread the sound more effectively, improving the sound pressure level of the speaker. The material of the horn will also affect the sound effect. The common materials include plastic, metal, polyester fiber, etc. Different materials will affect the reflection, absorption and reproduction of sound, thus affecting the sound quality performance of the speaker. Generally speaking, the horn design of a speaker is one of the important factors affecting the sound effect of the speaker, and a reasonable horn design can improve the sound performance and sound quality of the speaker.
