Abstract
The utility model relates to a speaker box made of glass fibre reinforcement molding plastics. The utility model comprises a box body and a speaker unit, wherein, the speaker unit is fixed on a box wall of the box body which is made of unsaturated polyester glass fibre reinforcement molding plastics which are taken as material, and the box wall of the box body is provided with an opening. The utility model can be made into various shapes, and has strong rigidity. The utility model has the advantages that the utility model eliminates the box body resonance of the speaker box and is made into various main and auxiliary speaker boxes, the utility model is suitable for mass production, etc.
Description
The utility model relates to a kind of terminal installation of sound system.
Traditional audio amplifier is made by nonrigid materials such as stone material, timber, plastics, though adopt its tonequality of audio amplifier of timber, stone material better, because the external form of timber, sound resonator of stone material lacks plasticity, is difficult to be made into desired shapes and is suitable for using.The common plastics audio amplifier has characteristics such as external form plasticity is strong, but this sound box hardness is little, causes the resonance of casing easily when playing the low frequency music, and makes the sound system distortion.
The purpose of this utility model provides a kind of existing plasticity preferably, and the glass fibre reinforced mould plastic audio amplifier of stronger hardness is arranged again, and it can make various external form shape can eliminate the resonance distortion of audio amplifier when bass again.
For achieving the above object, the technical solution of the utility model is a kind of glass fibre reinforced mould plastic audio amplifier, and it comprises casing, loudspeaker unit, and loudspeaker unit is fixed on the tank wall of casing, casing is that material is made by glass fiber reinforced unsaturated polyester plastic, and the casing tank wall has opening.
Compare with traditional audio amplifier, because the sound box that the utility model adopts glass fiber reinforced unsaturated polyester plastic (BMC) to make for material.Therefore, can be molded as various shape, and have very strong rigidity, the casing resonance of having eliminated audio amplifier can be made into various major-minor audio amplifiers, is suitable for advantages such as large batch of production.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model glass fibre reinforced mould plastic audio amplifier front view.
Fig. 2 is a glass fibre reinforced mould plastic loudspeaker box structure end view shown in Figure 1.
Glass fibre reinforced mould plastic audio amplifier shown in Fig. 1, the diagram, be to constitute by casing 1, loudspeaker unit 2 etc., loudspeaker unit 2 is fixed on the tank wall of casing 1, and the material of casing 1 is a glass fiber reinforced unsaturated polyester plastic, and casing 1 tank wall has opening 5.Casing 1 tank wall opening 5 places are provided with the fixedly fixture of loudspeaker unit 2.This fixture is that casing 1 tank wall opening 5 places offer hole 3 according to loudspeaker unit 2 positions, establishes rivet 4 in the hole 3, and fixedly loudspeaker unit 4.
Loudspeaker unit 2 covers opening 5 places of casing 1 tank wall, makes its good looking appearance, and the bass distortion is little.
