Description

Anti-resonance supporting device of box loudspeaker Technical Field The utility model relates to the technical field of sound equipment, in particular to an anti-resonance supporting device of a box loudspeaker. Background The cabinet horn refers to a sound system in which a speaker unit is installed in a cabinet of a specific structure to optimize sound performance. The main function of the cabinet is to prevent the sound waves from canceling each other (acoustic short circuit) before and after the speaker, enhance the low frequency response, and reduce distortion. When the loudspeaker unit emits sound, the air in the box forms standing waves, so that the box emits resonance, the resonance can be conducted to the placed position, and larger noise can be generated besides the sound of the box, so that the hearing is influenced, and therefore the anti-resonance supporting device of the box loudspeaker is designed to solve the problem. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides an anti-resonance supporting device of a box loudspeaker, which solves the problems that the existing box loudspeaker is directly placed on a table top or a tea table, and can resonate with the place where the table, the tea table and the like are placed to form larger noise when making sound.
