Abstract
The invention relates to a composite material loudspeaker, the case is made of ceramics or refined ceramics material. There are an outer surface layer covered on the outer surface of the loudspeaker case, an elastic material layer fit on inner surface of the loudspeaker case and an acoustic layer covered on the inner surface of the elastic material layer. The erection holes of the voice box and the loudspeaker are poured by steel wire and atomic ash. A reinforcing layer can be added between the inner surface of the loudspeaker case and the elastic material layer. The advantages are: better reproducing effect, high intensity, low cost, artistical box surface and without pollution to environment.
Description
The present invention relates to a kind of sound enclosure made of composite material.
At present, audio amplifier of the prior art mostly is greatly and adopts wood materials to be made, the audio amplifier that these adopt wood materials to make, its shortcoming is: the screening to timber is very strict, the quality of timber is required very high, and it is to the processing of timber with to make the technology of audio amplifier all very complicated, and this not only will waste the timber resources of a large amount of preciousnesses, but also caused higher cost of manufacture, and wood materials audio amplifier ubiquity, and appearance and modeling is single, the shortcoming of decorative surface difference.For addressing this problem, number of patent application is 95106972.1, denomination of invention once disclosed a kind of technical scheme of main employing ceramic material audio amplifier for the Chinese patent application document of " ceramic loudspeaker box ", though this scheme has been saved a large amount of timber, has multifarious moulding and ornamental preferably, but because the defective of its manufacture craft, it is not good enough to make its product exist playback effect, the breakable shortcoming of sound box bodies, and the audio amplifier loud speaker installing hole edge of this technical scheme is easy to by the vibrations of loud speaker and shatter, its loud speaker is also easily leaked gas by the poly-rare faintly acid gas attack of acetic acid second and blistering comes off, in addition, owing to adopted mineral wool as sound absorbing layer in this technical scheme, the glass fibre of this mineral wool is easy to be dispersed into the air by the voice guide hole of vibrations air-flow from audio amplifier, thereby causes the pollution to environment.
The purpose of this invention is to provide that a kind of playback effect is better, intensity is higher, environmentally safe, saving timber, be convenient to the sound enclosure made of composite material of multiple moulding.
The present invention constitutes like this: it comprises the voice box casing (1) that adopts ceramic material, voice box casing (1) also can adopt the fine pottery material, topped on the outer surface of voice box casing (1) have one deck extexine (2), nexine at voice box casing (1) is lined with one deck elastomeric layer (3), one deck sound absorbing layer (4) arranged in that the inner surface of elastomeric layer (3) is topped, the loud speaker installing hole (5) of audio amplifier is to adopt steel wire and the cast of atom ash to form; The strengthening course (6) that between the inwall of voice box casing (1) and elastomeric layer (2), also can have one deck to form with steel wire and atom ash casting solidification; Extexine (2) can adopt glaze or adopt wooden or metal plastic composite material or engineering fire proofing are made; The material of elastomeric layer (3) is rubber and natural or artificial synthetic macromolecular compound elastomeric material; Sound absorbing layer (4) adopts free of contamination non-glass fiber environment friendly acoustical absorption cotton; The component structure of fine pottery material is:
SiO

3The total amount of 0.25%～1.2% above each element of component and be absolutely.
Owing to adopted technique scheme, the toughness and the shock resistance of sound box of the present invention improve greatly, thermal stability and sound absorption qualities are better, its tonequality is purer, the present invention does not adopt poly-acetic acid second rare, there is not faintly acid gas, thereby its loud speaker can not be corroded and leaks gas or blistering comes off, so, the present invention compares with existing audio amplifier, has that playback effect is better, intensity is higher, environmentally safe, saving timber, is convenient to diversified moulding, attractive in appearance, the advantage of low manufacturing cost of tank surface.
Accompanying drawing 1 is the structural representation of the embodiment of the invention 1;
Accompanying drawing 2 is the structural representation of the embodiment of the invention 2;
