Abstract
The utility model discloses a sound box vibration reduction structure, which comprises a box body, wherein the bottom portion of the box body is provided with a vibration reduction seat, a loudspeaker support is arranged in the box body, at least a loudspeaker fixing cavity is arranged on the support, the cavity wall of the loudspeaker fixing cavity is provided with a vibration reduction pad, the box body is provided with a through hole which corresponds to the loudspeaker fixing cavity, and the bottom portion of the support is provided with a vibration absorber which is connected with the box body. The sound box vibration reduction structure can reduce the vibration of a sound box, and reduces murmur.
Description
Technical field
The utility model relates to a kind of audio amplifier, particularly a kind of audio amplifier vibration-proof structure.
Background technology
In the prior art, audio amplifier mainly is made up of members such as loud speaker, casings.When the speaker operation sounding, casing also can forced vibration. and the vibration of casing is harmful to, and can produce noise during the casing vibration, destroys acoustics, can cause the object judder in the surrounding environment when serious, influences normal audition.In addition, noise and vibration have very confidential relation, have many noises to bring out generation by vibration.The vibration of audio amplifier passes by solid especially ground and body of wall, beam, post shakes, and outside radiated noise is transmitted noise in communication process.The major technique measure of control audio amplifier vibration noise is simply to use cushion blocking at present, and the shortcoming of this kind method is that effectiveness in vibration suppression is poor, can not satisfy requirement of engineering.
Summary of the invention
The purpose of this utility model provides a kind of audio amplifier vibration-proof structure, and the utility model can reduce the vibration of audio amplifier, reduces noise.
The technical scheme that realizes the utility model purpose is as follows:
The audio amplifier vibration-proof structure, comprise casing, described bottom half is provided with vibration proof mounting, be provided with loudspeaker support in the casing, at least be provided with a loud speaker lock chamber on the loudspeaker support, the chamber wall of this loud speaker lock chamber is provided with cushion blocking, and described casing is provided with the through hole corresponding with the loud speaker lock chamber, and the two ends of described loudspeaker support are provided with the vibration isolator that is connected with casing.
Described vibration proof mounting comprise upper backup pad, lower supporting plate and be installed in upper backup pad and lower supporting plate between damping shock absorber.
The lower surface of described upper backup pad is provided with rubber blanket, and the upper surface of described lower supporting plate also is provided with rubber blanket.
Described vibration isolator is the vibration damping foam.
Adopted such scheme, described bottom half is provided with vibration proof mounting, by vibration proof mounting, can absorb casing and be delivered to extraneous vibration, avoids environment is formed unnecessary noise.Be provided with loudspeaker support in the casing, at least be provided with a loud speaker lock chamber on the loudspeaker support, the chamber wall of this loud speaker lock chamber is provided with cushion blocking, described casing is provided with the through hole corresponding with the loud speaker lock chamber, by loud speaker being installed on the through hole of loudspeaker support and casing, can improve the stability of loud speaker, and on loudspeaker support for loud speaker is provided with cushion blocking, can reduce transfer of vibration.The bottom of support is provided with the vibration isolator that is connected with casing, can further reduce transfer of vibration to casing by vibration isolator.The utility model helps reducing the vibration of audio amplifier by damping means such as vibration isolator and cushion blocking are set in a plurality of positions, reduces noise and noise.
