Abstract
The utility model relates to a composite sound box panel, which comprises a core material 1, a first face layer 3 stuck to one face of the core material 1 by hot pressing compounding via a heat plasticity adhesive 2, a second face layer 5 stuck with the other face of the core material 1 by hot pressing compounding via a thermoplastic adhesive 4, wherein the core material 1 is a plastic or comb core material made of aluminium; the thermoplastic adhesives 2 and (4) are the modified sticking resin of polyethylene class. The composite sound box panel adopts the thermoplastic adhesive to compound the comb core material and the two face layers by hot pressing compounding. Because the sticking adhesive layer is soft and flexible, the sticking adhesive layer can carry out roll bending processing for fabricating the composite sound box panels of different figures. By making use of the utility model, the plane sound box of different figures can be fabricated to satisfy the needs of different purposes; therefore, the problem that aluminium panels are shaped first and then compounded and moulds are needed in compounding can be avoided. The utility model has the advantages of labor saving, resource saving, good sound effect, high strength, light quality and difficult deformation.
Description
Technical field
The utility model relates to the electroacoustic techniques field, more particularly, relates to a kind of complex tone boxboard that various planes audio amplifier improves acoustical quality that can be used for.
Background technology
Therefore and production cycle that prolongs and increase manufacturing expense existing sound box panel adopts the single structure material more, also have to adopt composite material, but shape is single mostly, and to change moulding need mould, and, simultaneously, sound effect is also not ideal enough.
The utility model content
The technical problems to be solved in the utility model is, a kind of novel audio amplifier sheet material is provided, and can overcome the above-mentioned shortcoming of prior art, can carry out moulding as required and mould specially, can guarantee that sound effect reaches best simultaneously.
The above-mentioned technical problem of the utility model solves like this, construct a kind of complex tone boxboard, comprise one or more cores 1, also comprise by first surface layer 3 of thermoplastic adhesive's 2 hot pressing compoiste adherings on 1 one faces of core, and by second surface layer 5 of thermoplastic adhesive's 4 hot pressing compoiste adherings on core 1 another face.
In the complex tone boxboard that provides according to the utility model, described core 1 is plastics or aluminum comb core.
In the complex tone boxboard that provides according to the utility model, described thermoplastic adhesive 2 and 4 is a modified poly ethylene class binding resin.
In the complex tone boxboard that provides according to the utility model, can carry out the roll bending moulding by three roller roll bending machines.
In the complex tone boxboard that provides according to the utility model, first surface layer 3 is compound through heating and pressurizing, combines with comb core 1 by thermoplastic adhesive 2.
In the complex tone boxboard that provides according to the utility model, second surface layer 5 is compound through heating and pressurizing, combines with comb core 1 by thermoplastic adhesive 4.
The complex tone boxboard that enforcement provides according to the utility model is combined into the complex tone boxboard with comb core and two surface layer hot pressing.Because adopt the thermoplastic adhesive, glue line is soft and tough, so this complex tone boxboard can carry out roll bending processing, to make difform complex tone boxboard.Roll bending processing adopts three common roller roll bending machines to get final product.Utilize the utility model, can produce the plane audio amplifier of different shaping, satisfy the needs of different purposes; Have that sound effect improves simultaneously and intensity height, light weight, on-deformable advantage are arranged.
Description of drawings
Fig. 1 is the structural representation according to the utility model complex tone boxboard;
Embodiment
As shown in Figure 1, complex tone boxboard of the present utility model, one or several core 1 is arranged, can be bonding between core and the surface layer, in first surface layer 3, another face of core also passes through thermoplastic adhesive's 4 hot pressing compoiste adherings in second surface layer 5 to a face of core by thermoplastic adhesive's 2 hot pressing compoiste adherings.Core 1 can be to be plastics or aluminum comb core.Surface layer 3 and 5 can be aluminium lamination, alloy-layer or other composite layer.And thermoplastic adhesive 2 and 4 is a modified poly ethylene class binding resin, so that make produced complex tone boxboard, can carry out the roll bending moulding by three roller roll bending machines.The complex tone boxboard of this spline structure, owing to adopt the thermoplastic adhesive, glue line is soft and tough, so the surface sound boxboard can carry out roll bending processing, to make difform audio amplifier, its sound field is changed, in the hope of improving the acoustical quality of surface sound boxboard.The utility model adopts the thermoplastic adhesive that the surface layer of plane audio amplifier and bottom and the hot pressing of plastics (or aluminium) comb core are combined into the surface sound boxboard.
Claims (3)
