Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed description.
Embodiment one: Fig. 1 is the three-dimensional decomposition texture sketch map of the utility model embodiment one Microspeaker vibrating diaphragm; Fig. 2 is the stereogram of the utility model embodiment one Microspeaker vibrating diaphragm; As depicted in figs. 1 and 2, the Microspeaker vibrating diaphragm comprises flexible vibrating diaphragm body 2 and the composite bed 1 that is incorporated into vibrating diaphragm body 2 centers.Wherein composite bed 1 has rigidity and elasticity simultaneously; And be the material of lightweight; Composite bed 1 is provided with some first air-vent, 101, the first air-vents 101 can make composite bed 1 effectively dispel the heat, thereby can avoid composite bed 1 temperature distortion and influence the acoustical behavior of vibrating diaphragm.
Fig. 3 is the three-dimensional decomposition texture sketch map of the utility model embodiment one composite bed; As shown in the figure; Composite bed 1 comprises the foaming body 12 of lightweight and is incorporated into the aluminium foil 11 of foaming body 12 away from the uper side surface of vibrating diaphragm body 2; To shown in Figure 3, aluminium foil 11 can increase the integral rigidity of composite bed 1 like Fig. 1, promotes the high frequency characteristics of Microspeaker vibrating diaphragm.In the present embodiment; Aluminium foil 11 is provided with the first circular air-vent 101; First air-vent 101 can effectively shed the heat that produces in composite bed 1 course of work; Thereby can avoid composite bed 1 temperature distortion and influence the acoustical behavior of Microspeaker vibrating diaphragm, improve the stability of Microspeaker vibrating diaphragm.
In addition, the distributing position and the number of first air-vent 101 are not limit, with the rigidity that do not influence composite bed and can effectively dispel the heat and be as the criterion.
Embodiment two: Fig. 4 is the three-dimensional decomposition texture sketch map of the utility model embodiment two composite beds; As shown in the figure; The main distinction of present embodiment and the foregoing description is; The downside surface of present embodiment foaming body 12 also is combined with aluminium foil 13, can further increase the rigidity of composite bed 1 in conjunction with aluminium foil 13, puies forward the high frequency characteristics of Microspeaker vibrating diaphragm.In addition, first air-vent 101 ' on the present embodiment upside aluminium foil 11 is a strip, and composite bed 1 is effectively dispelled the heat, and avoids composite bed 1 temperature distortion and influences the acoustical behavior of Microspeaker vibrating diaphragm, has improved the stability of Microspeaker vibrating diaphragm.
In addition, the shape of air-vent is not limited to the shape of above-mentioned circle or strip, also can be other rule or irregular shapes such as oval, square, all can realize the efficiently radiates heat of composite bed 1.
