Abstract
The utility model relates to a hollow vibrating film for a drive type loud-speaker at the circumference of a vibrating film, which is designed for solving the problem that the rigidity and weight of the existing loud-speaker vibrating film are difficult to reach harmony and unification. The utility model comprises a plane film and a concave film; the edges of the plane film and the concave film are connected together to form a cavity structure at the interior of the plane film and the concave film. The utility model carries out a design on the structure of the vibrating film so as to reach the harmony and unification of the rigidity and weight of the vibrating film and has the advantages of high rigidity and light weight, thus lifting the tone and the sensitivity of a loud-speaker unit.
Description
Technical field
The utility model relates to a kind of diaphragm of loudspeaker.
Background technology
The factor that influences the loudspeaker unit performance is a lot, and wherein vibrating diaphragm is one of key factor.Desirable vibrating diaphragm requires rigidity to want high usually, and the dynamic deformation of vibrating diaphragm is little like this, can effectively suppress to cut apart vibration and ring antiresonance, makes the playback frequency response wide and level and smooth, and the distortion factor is little.In addition, desirable vibrating diaphragm also requires the weight of vibrating diaphragm to want light, helps improving electro-acoustic conversion efficiency, and can reach transient response characteristic preferably.But, in the application of reality,, be difficult to make the rigidity of vibrating diaphragm and weight all to reach desirable requirement owing to be subjected to the restriction of material, improve the increase that rigidity can cause weight usually, and weight reduction then can reduce the rigidity of vibrating diaphragm.This contradiction is perplexing the loudspeaker design engineers for a long time always, and is special in the bigger material of those density, and reach same rigidity needs heavier weight usually.
In addition, in some applications, adopt at taper cone surface coverage one deck plane diaphragm of conventional loudspeakers and use to form similar panel speaker.The taper cone of this structure connects voice coil loudspeaker voice coil at core, this working method is owing to existing stronger cavity sound to restrict the raising of tonequality, usually the filler that partly adds lighter weight at cavity is improved, but is difficult to eliminate intermediate frequency peak in the frequency response to the influence of tonequality.
Summary of the invention
The purpose of this utility model is the problem that the rigidity that exists at the existing diaphragm of loudspeaker and weight are difficult to reach the coordinating and unifying, and a kind of high rigidity, the hollow vibrating diaphragm of lightweight vibrating diaphragm periphery repulsive-type maglev loud speaker are provided.
The purpose of this utility model is achieved in that the utility model comprises planar diaphragm and concave surface diaphragm, and they link together and constitute cavity structure in inside in edge.
Technique effect of the present utility model is: the utility model designs on the structure of vibrating diaphragm, reach the coordinating and unifying of vibrating diaphragm rigidity and weight, vibrating diaphragm of the present utility model has adopted hollow mechanical structure form, the combination of its concave surface diaphragm and planar diaphragm has strengthened the integral rigidity of vibrating diaphragm with the working method that is similar to the triangle mechanics, its internal cavity structures has reduced the overall weight of vibrating diaphragm again to greatest extent simultaneously, therefore the utility model vibrating diaphragm has reached high rigidity, lightweight purpose, has promoted the tonequality and the sensitivity of loudspeaker unit.In addition, the utility model is applied to vibrating diaphragm peripheral drive type loud speaker, setting that mid portion on the vibrating diaphragm surface is not connected with voice coil loudspeaker voice coil such as voice coil loudspeaker voice coil connection hole etc., but be connected with voice coil loudspeaker voice coil to form vibrating diaphragm peripheral drive form at the edge of vibrating diaphragm, both strengthen the integral rigidity of vibrating diaphragm, solved cavity mail topic again.

Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the structural representation of the utility model embodiment two.
Fig. 4 is the structural representation of the utility model embodiment three.
Embodiment
Referring to Fig. 1 and Fig. 2, the vibrating diaphragm of embodiment one is made of planar diaphragm 1 and concave surface diaphragm 3, and planar diaphragm 1 and concave surface diaphragm 3 are glued together in edge, and constitute the cavity structure 2 of sealing in inside.Planar diaphragm 1 and concave surface diaphragm 3 also can be that direct punching press combines.Embodiment one midplane diaphragm 1 and curved surface diaphragm 3 are that the PVC material is made by transparent pvc material, thereby have made transparent vibrating diaphragm.
The utility model concave facial mask sheet can adopt different shape, for example: the concave surface diaphragm among the embodiment one is a spherical concave surface diaphragm, concave surface diaphragm 4 among the embodiment two shown in Figure 3 is a taper seat type concave surface diaphragm, and the concave surface diaphragm 5 among the embodiment three shown in Figure 4 is a parabolic type concave surface diaphragm.
Embodiment two, embodiment three only are that with the difference of embodiment one shape of concave surface diaphragm is different.
When the described vibrating diaphragm of the foregoing description was applied to vibrating diaphragm periphery repulsive-type maglev loud speaker, voice coil loudspeaker voice coil was connected vibrating diaphragm periphery and ring junction part, formed vibrating diaphragm periphery repulsive-type maglev loud speaker with ring-like internal magnetic circuit or external magnetic circuit system.
Planar diaphragm in the utility model and concave surface diaphragm also can adopt other transparent material for example polymethyl methacrylate etc. make, also can adopt non-transparent material to make.
Claims (4)
1. the hollow vibrating diaphragm of vibrating diaphragm periphery repulsive-type maglev loud speaker is characterized in that: comprise planar diaphragm and concave surface diaphragm, they link together and at inside formation cavity structure in edge.
