Problems solved by technology

[0007] The problem to be solved by the present invention is that the volume of the existing band-pass bass speaker box is relatively large, the air flow velocity of the box body is uncontrollable, and it is difficult to meet the defects of the sound color of the bass speaker and its sound power diversification. Subwoofer, which not only improves the accuracy and flexibility of the acoustic performance and quality of the low-frequency processing of the speaker, but also reduces the volume of the speaker, saving costs and resources

Abstract

The invention relates to the technical field of electroacoustics, in particular to a band-pass type bass loudspeaker box and an adjusting method of the band-pass type bass loudspeaker box. The band-pass type bass loudspeaker box comprises a bass loudspeaker box body, wherein at least one horizontally-arranged partition plate is arranged in the bass loudspeaker box body, the partition plate is provided with at least one low-frequency loudspeaker, low-frequency resonators are arranged on the portions, above and below the partition plate, of the wall of the bass loudspeaker box body, and therefore the bass loudspeaker box body is divided into an upper low-frequency bass loudspeaker box body and a lower low-frequency bass loudspeaker box body. The bass loudspeaker box body is provided with voltage regulating bins, wherein the outer section of each low-frequency resonator is connected with the corresponding voltage regulating bin to form an acoustic resonance access, the voltage regulating bins are provided with damping holes, and sound absorption bodies are arranged in the voltage regulating bins. The number of the low-frequency loudspeakers and the combination mode of the low-frequency loudspeakers can be increased according to requirement of acoustic characteristics. The damping value and the Q value of the bass loudspeaker box are adjusted respectively by means of adjusting the total area of the damping holes and the sound absorption bodies. By means of the adjusting method, the low-frequency processing acoustic performance of the band-pass type bass loudspeaker box and the quality accuracy and the flexibility of the band-pass type bass loudspeaker box are improved. Since the band-pass type bass loudspeaker box is small in volume, cost can be reduced.

Description

[0001] technical field [0002] The invention relates to the field of electro-acoustic technology, in particular to a band-pass subwoofer sound box and an adjustment method thereof. Background technique [0003] From the perspective of the acoustic structure of the speaker box, since the open-back speaker appeared in 1924, the current acoustic structure applications of speakers mainly include closed and open. There are fewer types of closed speakers, mainly air cushion and push. There are two pull styles. There are many types of vented speakers, such as inverted, two-stage inverted, empty paper cone, labyrinth, bandpass, pipe, rear horn, 1 / 4 wavelength loaded, transmission line, Colton formula and so on. [0004] The common feature of open-type speakers is to use the speaker as the drive to resonantly couple the air in the box cavity with the resonator (usually called an inverted tube), so as to maximize the drive energy of the speaker into the resonance energy of the box ...
