Abstract

The invention discloses a double woofer sound box, which comprises a sound box base, a sound box shell, a support column, a speaker bracket, a woofer, a first sound guiding cavity and a second sound guiding cavity. Compared with the prior art, the present invention reduces The overall volume of the speaker is small, which is easy to carry and fix. In addition, it reduces the mutual interference between the woofers, enhances the low-frequency efficiency, eliminates audio distortion, and concentrates the bass radiation field.

Description

【Technical field】 [0001] The invention relates to the technical field of sound boxes, in particular to a double woofer sound box. 【Background technique】 [0002] A speaker refers to a device that converts an audio signal into sound. In layman's terms, it refers to the built-in power amplifier in the main box of the speaker or the subwoofer box. After the audio signal is amplified, the sound is played back by the speaker itself to make the sound louder. [0003] As a kind of speaker speaker, the woofer speaker can be seen in various entertainment scenes. The arrangement order of the woofers in the existing double woofer speakers is mostly one-way side by side. This method not only increases the The volume of the speaker box makes it difficult to carry the speaker box, and the distance between the two woofers arranged side by side is too small to easily interfere with each other mechanically, resulting in audio distortion and concentrated bass radiation field. 【Content of i...
