Problems solved by technology

[0003] The speaker itself includes a speaker shell, a speaker, and a frequency divider. The quality of the speaker and the frequency divider accounts for 70% of the impact on the sound quality, and the impact of the speaker shell on the sound quality accounts for 30%, because the speaker and the frequency divider affect the sound quality. The impact is relatively large, so most people in the prior art are improving speakers and frequency dividers, but few people are improving speaker shells
[0004] But the speaker shell also has a great impact on the sound quality of the speaker, wherein the most important impact is the resonance of the speaker, and because the speaker of the prior art is mainly to fasten the basin frame of the speaker on the front panel of the speaker housing by screws , that is, the pot frame is directly in contact with the front panel, so the vibration generated when the speaker is working will be directly transmitted to the front panel of the speaker shell through the support structure such as the pot frame, and then the speaker shell will resonate, and some speakers will pass through The bracket fixes the speaker on other panels, so that the speaker will directly transmit the vibration to the fixed panel when it is working, causing the speaker shell to resonate, making the sound quality of the speaker sound poor; The sound wave pressure will also directly stimulate the speaker shell to vibrate, which will also lead to poor sound quality from the speaker

Abstract

The invention relates to the technical field of sound systems, and more particularly to a vibration attenuation sound box. In the vibration attenuation sound box, a loudspeaker is suspended through an electromagnet, a sound box shell is made of a vibration attenuation board, and a vibration attenuation base is arranged at the bottom of a bottom board. The sound box has smaller resonance and has good tone quality.

Description

technical field [0001] The invention relates to the technical field of audio systems, in particular to a vibration-damping sound box. Background technique [0002] The speaker is the last and most important component in the entire audio system process. Its playback quality has a great impact on the performance of the entire system. According to professional estimates, the contribution of speakers to the entire audio system accounts for more than 30% of the entire system. [0003] The speaker itself includes a speaker shell, a speaker, and a frequency divider. The quality of the speaker and the frequency divider accounts for 70% of the impact on the sound quality, and the impact of the speaker shell on the sound quality accounts for 30%, because the speaker and the frequency divider affect the sound quality. The impact is relatively large, so most people in the prior art are improving speakers and frequency dividers, but few people are improving the speaker housing. [0004]...
