Abstract
The utility model relates to a compound cone, which forms a compound lamellar structure. An inner layer of the cone is a light metal material layer, an upper surface layer and a lower surface layer of the cone are both compounded with polypropylene layers, and the three layers are tightly compounded in one. The compound cone is adopted to satisfy the characteristics of small material density, high material mechanical strength, and proper internal damping of the cone. The utility model retains the use functions and the advantages of the prior art. The utility model has the advantages of simple manufacture process, beautiful appearance, and beautiful tone quality. The utility model is an ideal novel cone.
Description
The utility model relates to a kind of sounding parts that are mainly used in speaker vibration system, specifically refers to a kind of novel complex tone basin.
Loud speaker (loudspeaker) mainly is made up of vibrational system and magnetic circuit system, and the sound basin then is the critical piece of vibrational system.The frequency characteristic of loud speaker be decided by the performance of sound basin to a great extent, and the performance of sound basin is decided by the material of sound basin.In general, requirement for the sound cone material, will possess three specific characters simultaneously: the density of material is little, the mechanical strength of material wants big and it is suitable internally-damped to have, existing sound basin structure and the material that is adopted thereof, as strengthen in the honeycomb metal plate structure of foaming or papery, the composite polypropylene and add carbon fiber, glass fibre, mica etc., though this structure has solved the problem of materials of sound basin preferably, existing sound cone material all is difficult to all satisfy comparatively ideally simultaneously three specific character requirements of above-mentioned sound basin.
The purpose of this utility model just is to provide a kind of novel complex tone basin, to adopt by its sound basin main body by light metal as internal layer and the polyacrylic complex structure of surface recombination, make it can satisfy three specific characters of sound cone material preferably, in function of use that keeps prior art effectively and advantage, has the advantage that manufacture craft is simple, handsome in appearance and tonequality is graceful.
The purpose of this utility model realizes in the following manner: a kind of novel complex tone basin, mainly form by cushion rubber and sound basin, above-mentioned cushion rubber is glued at the periphery of sound basin, it is characterized in that above-mentioned sound basin is compound layer structure, its sound basin internal layer is the lightweight metal material layer, its sound basin upper surface layer and undersurface layer all are compounded with polypropylene layer, above-mentioned three layers closely compound be one.
Adopt a kind of novel complex tone basin of the present utility model, because its sound basin main body has adopted by light metal as internal layer and the polyacrylic composite construction of surface recombination, thereby the density of material that has satisfied the sound cone material preferably is little, the mechanical strength of material wants big and have suitable internally-damped three specific characters, in function of use that keeps prior art effectively and advantage, having the advantage that manufacture craft is simple, handsome in appearance and tonequality is graceful, is a kind of comparatively desirable novel sound basin.
Description of drawings:
Fig. 1 is a kind of example structure schematic diagram of the present utility model;
Fig. 2 is the sound basin partial structurtes enlarged diagram of Fig. 1.
Wherein: 1-cushion rubber, 2-sound basin, 3-upper surface layer, 4-sound basin internal layer, 5-undersurface layer.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, a kind of novel complex tone basin of the present utility model, mainly form by cushion rubber (1) and sound basin (2), above-mentioned cushion rubber (1) is glued on the periphery of sound basin (2), it is characterized in that above-mentioned sound basin (2) is compound layer structure, its sound basin internal layer (4) is the lightweight metal material layer, as metal films such as employing aluminium alloys, its sound basin upper surface layer (3) and undersurface layer (5) all are compounded with polypropylene layer, above-mentioned three layers closely compound be one.
Owing to adopted lightweight metal material as matrix, can make the sound basin keep certain intensity, and the polyacrylic employing of its surface recombination, it is enough internally-damped that it has been possessed, and above-mentioned two kinds of materials all can satisfy sound cone material density and want little requirement.In addition, because the employing of said structure and material makes the outward appearance of sound basin be different from traditional metallic sound basin and traditional composite polypropylene sound basin, can satisfy people preferably and look for novelty and ask different requirement.
Claims (1)
- A kind of novel complex tone basin, mainly form by cushion rubber (1) and sound basin (2), above-mentioned cushion rubber (1) is glued on the periphery of sound basin (2), it is characterized in that above-mentioned sound basin (2) is compound layer structure, its sound basin internal layer (4) is the lightweight metal material layer, its sound basin upper surface layer (3) and undersurface layer (5) all are compounded with polypropylene layer, above-mentioned three layers closely compound be one.
