Abstract
The utility model discloses a miniature loudspeaker diaphragm, it includes the ball top and centers on the book ring that the ball top set up, the ball top is including the first layer, the second floor and the third layer that stack gradually, the first layer is wherein one kind of aluminium foil layer, titanium alloy layer and magnadure layer, the second floor is foaming polyester layer or honeycomb foam sheet layer, the third layer is wherein one kind of aluminium foil layer, titanium alloy layer and magnadure layer. The utility model provides a miniature loudspeaker diaphragm can guarantee the high frequency response and the reliability is high.
Description
[technical field]
The utility model relates to electroacoustic field, is specifically related to a kind of Microspeaker vibrating diaphragm.
[background technology]
In prior art, the vibrating diaphragm of Microspeaker generally includes ball top and the ring around the setting of described ball top, when high frequency, because the rigid on ball top is inadequate, often easily produce diaphagras thus affect voice quality, in addition, in the vibrating diaphragm course of work, a large amount of heats can be produced, if cannot well heat radiation ball top can be caused to lose efficacy in delivered heat to ball top, reliability be not high.
Therefore, be necessary to provide a kind of new technical scheme to overcome above-mentioned defect.
[utility model content]
The purpose of this utility model is to provide and a kind ofly can ensures high frequency characteristics and the high Microspeaker vibrating diaphragm of reliability.
The purpose of this utility model is achieved in that
A kind of Microspeaker vibrating diaphragm, it ring comprising ball top and arrange around described ball top, described ball top comprises the ground floor, the second layer and the third layer that stack gradually, described ground floor is aluminium foil layer, titanium alloy layer and magnadure layer one wherein, the described second layer is expanded polyester layer or cell foams flaggy, and described third layer is aluminium foil layer, titanium alloy layer and magnadure layer one wherein.
Preferably, the thickness of described ground floor is 2 μm to 5 μm.
Preferably, the thickness of described third layer is 2 μm to 5 μm.
The utility model has the following advantages: the Microspeaker vibrating diaphragm that the utility model provides can ensure high frequency characteristics and reliability is high.
[accompanying drawing explanation]
The structural representation of the Microspeaker vibrating diaphragm that Fig. 1 provides for the utility model;
The structural representation on the ball top of the Microspeaker vibrating diaphragm that Fig. 2 provides for the utility model.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, be the Microspeaker vibrating diaphragm 1 that the utility model provides, it ring 12 comprising ball top 11 and arrange around ball top 11.
In the lump with reference to Fig. 2, ball top 11 comprises the ground floor 11a, the second layer 11b and third layer 11c that stack gradually, ground floor 11a is aluminium foil layer, titanium alloy layer and magnadure layer one wherein, second layer 11b is expanded polyester layer or cell foams flaggy, and third layer 11c is aluminium foil layer, titanium alloy layer and magnadure layer one wherein.
The rigid that ground floor 11a and third layer 11c aluminium layers of foil, titanium alloy layer and magnadure layer improve ball top 11 on the one hand ensure that the high frequency characteristics on ball top 11, and the heat radiation adding ball top 11 on the other hand improves the reliability on ball top 11.The weight that second layer 11b selects expanded polyester layer or cell foams flaggy to reduce ball top 11 improves the sensitivity of Microspeaker vibrating diaphragm 1.
Preferably, the thickness of ground floor 11a is 2 μm to 5 μm, and the thickness of third layer 11c is 2 μm to 5 μm.
The foregoing is only better embodiment of the present utility model; protection range of the present utility model is not limited with above-mentioned execution mode; in every case those of ordinary skill in the art modify or change according to the equivalence that the utility model institute disclosure is done, and all should include in the protection range recorded in claims.
