Abstract
The utility model discloses a sound box cover. The sound box cover is a cube, and two adjacent side surfaces of the sound box cover are opened, and the inner side of a shell is equipped with a foam layer. Evenly distributed foam pyramids are arranged on the inner wall of the lateral foam layer, and a sound box is placed inside the sound box cover. The sound box cover is composed of multiple layers, so that the vibration propagation can be avoided effectively by different resonance frequencies among materials, and the foam layer can absorb a part of sound wave vibration by itself. The foam pyramids are arranged on the inner wall of the foam layer, so that a part of sound wave emitted by the walls of the sound box can be absorbed by the foam pyramids partially and can be blocked to propagate outwards to cause noise. The sound box cover enables the sound emitted by the sound box to be more pure, and the timbre effect to be improved.
Description
Technical field
The utility model relates to a kind of audio amplifier cover.
Background technology
Film occurs common sound equipment conventionally and casing exists rigid physical connection, while there are film vibrations, can drive audio amplifier jointly to vibrate, and the vibrations of audio amplifier occur under specific acoustic wave can produce noise, disturbs the normal sound wave that film occurs, and causes interference tones.And when the plane that audio amplifier contact desktop etc. is placed, also can relatedly resonate.
Summary of the invention
The purpose of this utility model is to overcome above deficiency and provides a kind of simple in structure, economic audio amplifier cover.
The utility model is realized by the following technical programs, and audio amplifier cover, is characterized in that, sound equipment cover is cube, wherein two adjacent lateral openings, shell inner side is provided with froth bed, and equally distributed foam pyramid is installed on the froth bed inwall of side.
The invention has the advantages that: the inner audio amplifier of placing of audio amplifier cover, because audio amplifier cover is made up of multilayer, therefore can pass through storeroom different resonant frequencies, effectively avoid Vibration propagation.Froth bed itself also can absorption portion acoustic vibration.Foam pyramid is installed on froth bed inwall, and the acoustic wave segment that audio amplifier wall sends can be partially absorbed by foam pyramid, and blocking-up is outwards propagated and caused noise.The sound that audio amplifier cover can make audio amplifier send is purer, promotes acoustical quality.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Wherein: 1, froth bed, 2, shell, 3, foam pyramid.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated:
As shown in Figure 1, audio amplifier cover, sound equipment cover is cube, wherein two adjacent lateral openings, shell 2 inner sides are provided with froth bed 1, on froth bed 1 inwall of side, equally distributed foam pyramid 3 are installed.
The inner audio amplifier of placing of audio amplifier cover, because audio amplifier cover is made up of multilayer, therefore can pass through storeroom different resonant frequencies, effectively avoids Vibration propagation.Froth bed 1 itself also can absorption portion acoustic vibration.On froth bed 1 inwall, foam pyramid 3 is installed, the acoustic wave segment that audio amplifier wall sends can be partially absorbed by foam pyramid 3, and blocking-up is outwards propagated and caused noise.The sound that audio amplifier cover can make audio amplifier send is purer, promotes acoustical quality.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make technical scheme of the present invention, all should fall in the definite protection range of the utility model claims.
