Problems solved by technology

[0002] At present, the subwoofer system needs to emit elastic and deep bass. The decisive factor is the use of aerodynamic and anti-phase sound pressure in the structural design of the cabinet. The conventional cabinet design is either large in size or small in size but the bass sound is not flexible and does not dive. Cannot meet the actual listening needs

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, and the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. To explain the present invention, but not as a limitation of the present invention.

[0016] It should be noted that all directional indications (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) If the specific posture changes, the directional indication will also change accordingly.

[0017] In the present invention, unless otherwise specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection, or It may be an electrical connection; it may be a direct connection, it may also be an indirect connection through an intermediary,...

Abstract

The invention discloses a compact small-volume bass structure, which comprises a box body, a woofer is arranged in the box body; the two sides of the woofer are respectively provided with a first zigzag sound guide channel and a second zigzag sound guide channel, wherein the cross sectional areas of the first zigzag sound guide channel and the second zigzag sound guide channel are 0.17 times of the equivalent loudspeaker diaphragm area. The total path length of the first zigzag sound guide channel and the second zigzag sound guide channel is one fourth of the wavelength of the low-frequency center frequency. The first zigzag sound guide channel and the second zigzag sound guide channel are each provided with at least one partition plate. A first semi-vent hole is formed in one end, far away from the woofer, of the first zigzag sound guide channel; a second semi-vent hole is formed in one end, far away from the woofer, of the second zigzag sound guide channel; except for parts corresponding to the woofer, the first semi-vent hole and the second semi-vent hole, high-elasticity rubber foaming EVA is attached to the inner wall of the box body. The compact small-volume bass structure is small in size and thin in thickness, low-frequency elasticity is achieved, and low-frequency diving is taken into account.

Description

technical field [0001] The invention relates to the technical field of subwoofer speakers, in particular to a compact and small-volume subwoofer structure. Background technique [0002] At present, the subwoofer system needs to emit elastic and deep bass. The decisive factor is the use of aerodynamic and anti-phase sound pressure in the structural design of the cabinet. The conventional cabinet design is either large in size or small in size but the bass sound is not flexible and does not dive. Can not meet the actual listening needs. Contents of the invention [0003] The object of the present invention is to provide a compact and small-volume bass structure with small volume, thin thickness, low-frequency flexibility and low-frequency dive. [0004] The present invention is realized through the following technical solutions: [0005] A compact and small-volume bass structure, comprising a box body; a woofer is arranged inside the box; first meander guides with a cross-...
