Embodiment Construction

[0020] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 , image 3 , Figure 4 and Figure 6 As shown, a sound box with good sound quality includes a box body 1, a speaker 2 and an anti-phase anti-phase member 3 arranged inside the box body 1. The inner wall of the box body 1 is provided with a first sound-absorbing member 11, and the box body 1 is provided with a through hole for connecting the inside of the box body 1 with the outside of the box body 1, the speaker 2 is installed inside the through hole, the speaker 2 is provided with a diaphragm 21, and the anti-phase reversal component 3 includes an anti-phase reve...

Abstract

The invention relates to the technical field of sound boxes, in particular to a sound box with good tone quality, which comprises a box body, a loudspeaker and an anti-phase inversion piece arranged in the box body. A first silencing piece is arranged on the inner wall of the box body, the box body is provided with a through hole for communicating the interior of the box body with the exterior ofthe box body, and the loudspeaker is arranged in the through hole and is provided with a vibrating diaphragm. The anti-phase inversion piece comprises an anti-phase inversion part and a connecting part, the anti-phase inversion part is conical, the conical tip of the anti-phase inversion part faces the vibrating diaphragm, and the anti-phase inversion part is connected with the shell through the connecting part. According to the sound box, the first silencing piece is arranged on the inner wall of the box body, the conical anti-phase inversion part is arranged in the loudspeaker box, and the conical tip of the anti-phase inversion part faces the vibrating diaphragm of the loudspeaker, so that reverse-phase sound generated by the vibrating diaphragm can be directly absorbed by the first silencing piece or reflected to the first silencing piece by the anti-phase inversion part to reduce the interference of the reverse-phase sound on the vibrating diaphragm; therefore, the effects of welleliminating the reversed-phase sound and improving the sound quality of the sound box are achieved.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a sound box with good sound quality. Background technique [0002] When the speaker relies on the vibration of the diaphragm to produce sound, the back of the diaphragm will produce anti-phase audio at the same time. The anti-phase audio will interfere with and distort the normal operation of the diaphragm, causing pollution to the quality of the normal-phase audio in front of the diaphragm. At present, most ordinary speakers use internal partitions and sound-absorbing cotton to control and eliminate the interference of anti-phase audio on the diaphragm and maintain the sound quality of the speaker. However, because the structure and shape of the partition do not conform to the shape of the sound wave diffusion, the sound attenuation effect is poor. Contents of the invention [0003] Aiming at the problems in the prior art, the invention provides a sound box with good soun...
