Anti-resonance sound box

Abstract

The invention relates to an anti-resonance sound box which comprises a power amplifier device, a loudspeaker unit, a frequency divider, a fixing frame structure and a box body, wherein the box body comprises a base, a top plate and an anti-resonance wall, and the anti-resonance wall comprises a deformation cover and a cylindrical box plate; the deformation cover is arranged outside the box plate and comprises a shaping plate and a flexible layer, the shaping plate is parallel and opposite to the plate surface of the box plate, the side edges of the adjacent shaping plates are connected throughthe flexible layer, and the upper edge and the lower edge of the shaping plate are respectively connected with the outer wall of the box plate through the flexible layer; a closed annular barrel typecavity is formed by the deformation cover and the box plate; an injection valve is arranged on the shaping plate, the injection valve is communicated with the annular barrel type cavity, and the annular barrel type cavity is filled with anti-resonance liquid; the anti-resonance sound box is novel in structure and unique in principle, can provide enough firm and heavy performance for the box body,effectively reduces resonance during music playing, and can be conveniently transferred and carried.

Description

technical field [0001] The invention relates to audio equipment, in particular to a sound box. Background technique [0002] The sound of the speaker is mainly determined by the three major elements of the speaker unit, the structure design of the cabinet, and the frequency divider. For active speakers, power amplifier equipment is also required; The sound produced is not clear and pure; for this reason, many speaker manufacturers choose wooden structures to manufacture speakers, because the wooden structure is thicker and denser, which can effectively control resonance and box sound, effectively reduce sound dyeing, and thus obtain a more pure sound. Sound quality; but the so-called wooden structure is not natural solid wood, but processed and synthesized density fiberboard; in addition, there are also many speakers that use concrete cabinets; therefore, in theory, as long as the cabinet is strong enough, Thickness does not cause resonance, and any material is feasible; ho...
