Abstract
The utility model discloses a sound box, belonging to the field of sound equipment. The sound box comprises a plastic mesh enclosure, a front cover and a rear shell, wherein the upper surface and the lower surface of the front cover are respectively provided with an annular groove; the plastic mesh enclosure is clamped in the annular groove in the upper surface of the front cover; the rear cover is clamped in the annular groove in the lower surface of the front cover; and the surface of the plastic mesh cover is provided with a mesh fabric layer. The improved sound box is difficult to corrode, rust and deform.
Description
Technical field
The utility model relates to the sound appliances field, the audio amplifier that particularly a kind of plastic cement is made.
Background technology
At present, in the middle of the design of audio amplifier, in order to protect loud speaker to avoid to receive the damage of extraneous factor, the guard that tends to add layer metal material is screwed again, protects the loud speaker of audio amplifier; But the guard of metal material and screw are corroded easily, get rusty through making moist for a long time and the guard of metal material is easy to generate distortion.
The utility model content
The purpose of the utility model provides a kind of guard and is difficult for being corroded, gets rusty and on-deformable plastic cement audio amplifier.
The above-mentioned technical purpose of the utility model is achieved through following technical scheme: a kind of audio amplifier, comprise plastic cement guard, protecgulum and back cover, and the upper and lower surfaces of said protecgulum offers annular groove respectively; The plastic cement guard is stuck in the annular groove of preceding cover upper surface; Back cover is stuck in the annular groove of protecgulum lower surface; The surface of said plastic cement guard is provided with scrim layer; The bottom of said back cover is provided with spacing muscle; Inside at back cover is provided with loud speaker; The height value of said spacing muscle equals height poor of the back cover height loud speaker inner with placing back cover.
Preferred as the utility model, the inwall of said back cover is provided with positioning bar.
Preferred as the utility model, described positioning bar is upwardly extending cylinder from the bottom of back cover, on the surface of positioning bar near the back cover inwall, is provided with fixed block.
Preferred as the utility model offers the through hole of radius greater than the loud speaker radius on protecgulum.
Preferred as the utility model is covered with location hole preceding.
Preferred as the utility model, described location hole be lower surface from protecgulum to the cylinder that extends below and have endoporus, this location hole and positioning bar are on same axis, the interior pore radius of location hole is greater than the radius of positioning bar.
Preferred as the utility model is provided with one deck foam-rubber cushion in the bottom of loud speaker.
Preferred as the utility model is provided with cup dolly on the outer surface of back cover.
In sum, the beneficial effect of the utility model:
Because the guard of audio amplifier is that plastic cement is processed, and on the surface of plastic cement guard, posts one deck screen cloth, therefore, the outer surface of audio amplifier can not make moist through for a long time and be corroded, gets rusty, and plastic cement is high resilience, and guard also is not easy to produce distortion.
