Problems solved by technology

[0002] Due to the structural defects of the current speakers, standing waves are easily generated in the cabinet, which affects the low-frequency response of the speakers.
The current common way to eliminate standing waves is generally achieved by adding flat or wave-shaped sound-absorbing cotton to the cabinet, but the effect of this method is not ideal.

Embodiment 1

[0025] Such as Figure 1 to Figure 4 As shown, a sound box with the function of eliminating standing waves provided by this embodiment includes a box body 1, a sounding mechanism 2, and a front cover 3. The box body 1 is a hollow structure with one end open, and the front cover 3 is used for Covering the opening 4 of the box body 1, the sound producing mechanism 2 is installed in the box body 1, and a plurality of elimination structures 5 for eliminating standing waves are arranged in the box body 1.

[0026] Compared with the existing method of eliminating standing waves using flat or wave-shaped sound-absorbing cotton, the present invention improves the structure of the box 1, that is, a plurality of elimination structures 5 are arranged on the inner wall of the box 1 for Let the sounding mechanism 2 generate and spread the standing wave and when the standing wave hits the inner wall of the box body 1, the standing wave will enter the elimination structure 5 and collide with...

Embodiment 2

[0034] Such as figure 1 , Figure 5 and Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the box body 1 includes an outer casing 8 and an inner container 9, both of which are hollow structures with one end open, and the inner container 9 is arranged on the In the shell 8, the opening direction of the shell 8 is the same as the opening direction of the inner tank 9; the pronunciation mechanism 2 is installed in the inner tank 9, and the front cover 8 is used to cover the outer shell 8; Each elimination structure 5 is arranged on the inner wall of the inner container 9 . That is to say, no matter which method is used, the canceling structure 5 and the sounding mechanism 2 are both arranged in the same cavity, and there is no obstacle between the cavity and the sounding mechanism 2, so as to achieve the effect of eliminating standing waves.

[0035] Specifically, the material of the shell 8 can be any one of the materials mentioned in Embodim...

Abstract

The invention relates to the technical field of audio devices. The sound box with the standing wave eliminating function comprises a box body, a sounding mechanism and a front cover, the box body is of a hollow structure with an opening in one end, the front cover is used for covering the opening of the box body, the sounding mechanism is installed in the box body, and a plurality of eliminating structures used for eliminating standing waves are arranged in the box body. The elimination structure is arranged on the inner wall of the box body, so that sound waves are diffused into the elimination structure after being generated and collide with reflected waves to be eliminated, standing waves are prevented from being generated, and the effect of eliminating the standing waves is achieved.

Description

technical field [0001] The invention relates to the technical field of audio devices, in particular to a sound box with the function of eliminating standing waves. Background technique [0002] Due to the structural defects of the current sound box, standing waves are easily generated in the box, thereby affecting the low-frequency response of the sound box. The current common way to eliminate standing waves is generally achieved by adding flat or wave-shaped sound-absorbing cotton to the cabinet, but the effect of this method is not ideal. Contents of the invention [0003] Aiming at the problems in the prior art, the invention provides a sound box with the function of eliminating standing waves. By optimizing the structure of the box body, the effect of eliminating standing waves can be achieved without using sound-absorbing cotton and other components. [0004] In order to solve the above technical problems, the present invention adopts the following technical solution...
