Abstract
The utility model discloses a vibrating membrane, which comprises a middle layer, a first bonding layer and a second bonding layer respectively attached on two side surfaces of the middle layer, a first layer which is bonded by the first bonding layer and the middle layer and a second layer which is bonded by the second bonding layer and the middle layer, wherein the middle layer is made of one material selected from polyetherimide, polyethylene naphthalate, polyetheretherketone, and polyphenylene sulfide; and the first layer and the second layer are respectively made of one material selected from polyetherimide, polyethylene naphthalate, polyetheretherketone, and polyphenylene sulfide. The vibrating membrane provided by the utility model can enhance the tensile strength.
Description
[technical field]
The utility model relates to a kind of vibrating diaphragm and comprises the minitype acoustic generator of this vibrating diaphragm.
[background technology]
Mini-sound device is widely used in the portable electronic equipments such as mobile phone, notebook computer, hearing aids.Along with fast development, the people of these portable electronic equipments are more and more stronger to its Functional Requirement, the mini-sound device that is applied thereon is corresponding rapidly development also.
What the vibrating diaphragm in the middle of the minitype acoustic generator of correlation technique generally adopted is the vibrating diaphragm of three-decker, and two-layer polymer material layer is combined with each other by middle cementing layer up and down.Commonly bilevel material is polyarylate, and the material of middle cementing layer is acrylate glue.But the vibrating diaphragm tensile strength of this three-decker is poor, the rupture of membranes phenomenon can occur.
Therefore, be necessary to provide a kind of new technical scheme to overcome defects in fact.
[utility model content]
The purpose of this utility model provides a kind of vibrating diaphragm that can strengthen tensile strength.
The purpose of this utility model is achieved in that
A kind of vibrating diaphragm, this vibrating diaphragm comprises the intermediate layer, is attached to the first cementing layer on the both side surface of described intermediate layer and the second cementing layer and respectively by the first cementing layer and the ground floor of intermediate layer gummed and the second layer that glues together by the second cementing layer and intermediate layer respectively, the material in described intermediate layer is wherein a kind of of Polyetherimide, PEN, polyether-ether-ketone, polyphenylene sulfide, and the material of described ground floor and the second layer is respectively wherein a kind of of Polyetherimide, PEN, polyether-ether-ketone, polyphenylene sulfide.
Preferably, the material of described the first cementing layer and the second cementing layer is acrylate glue.
The utility model also provides a kind of minitype acoustic generator, and this minitype acoustic generator comprises aforesaid vibrating diaphragm.
The utlity model has following advantage: the vibrating diaphragm that the utility model provides can be strengthened tensile strength.
[description of drawings]
The five-layer structure schematic diagram of the vibrating diaphragm that Fig. 1 provides for the utility model;
Fig. 2 is for using the three-dimensional exploded view of the minitype acoustic generator of vibrating diaphragm among Fig. 1.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, the vibrating diaphragm 1 that provides for the utility model, this vibrating diaphragm 1 comprises intermediate layer 10, be attached to respectively the first cementing layer 11 and the second cementing layer 12 on 10 both side surface of described intermediate layer and pass through respectively the first cementing layer 11 and the ground floor 13 of intermediate layer 10 gummeds and the second layer 14 that glues together by the second cementing layer 12 and intermediate layer 10, the material in described intermediate layer 10 is Polyetherimide, PEN, polyether-ether-ketone, wherein a kind of of polyphenylene sulfide, the material of described ground floor 13 and the second layer 14 is respectively Polyetherimide, PEN, polyether-ether-ketone, wherein a kind of of polyphenylene sulfide, the material of described the first cementing layer 11 and the second cementing layer 12 is acrylate glue.
The vibrating diaphragm that the utility model provides is improved to the three-decker that attaches the first cementing layer and the second cementing layer in Polyetherimide, PEN, polyether-ether-ketone, these high-tensile macromolecule material film both side surface of polyphenylene sulfide with the middle cementing layer of vibrating diaphragm in the correlation technique, has strengthened the tensile strength of vibrating diaphragm.Another, ground floor and the second layer adopt the also whole tensile strength that has improved vibrating diaphragm of Polyetherimide, PEN, polyether-ether-ketone, these high-tensile macromolecule material films of polyphenylene sulfide.
As shown in Figure 2, the minitype acoustic generator 2 of this vibrating diaphragm 1 of use that provides for the utility model, described minitype acoustic generator 2 also comprises basin frame 20, be housed in magnetic bowl 21 in the basin frame 20, be housed in magnet steel 22, the pole piece 23 that is attached to magnet steel 22 surfaces and ends in the magnetic bowl 21 is suspended in voice coil loudspeaker voice coil 24 in magnet steel 22 all side magnetic gap, and these voice coil loudspeaker voice coil 24 other ends are retained on this vibrating diaphragm 1.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
Claims (3)
