The utility model technical problem to be solved provides a kind of electroacoustic transducer vibrating diaphragm, makes the big and stable performance of intensity of vibrating diaphragm, can be used for the large power, electrically sonic transducer.
To achieve these goals, the utility model provides a kind of electroacoustic transducer vibrating diaphragm, and said vibrating diaphragm comprises one deck basement membrane at least and the binder course of one deck at least that combines with said basement membrane, and wherein said basement membrane adopts polyetheretherketonematerials materials.
In addition, preferred scheme is that the number of plies of said basement membrane is two-layer, is provided with binder course between the two-layer said basement membrane.
In addition, preferred scheme is that said binder course is a glue-line.
In addition, preferred scheme is that the upside and/or the downside of said basement membrane are combined with binder course.
In addition, preferred scheme is that said binder course is a polyurethane.
In addition, preferred scheme is to be combined with the rigidity composite bed on the said vibrating diaphragm.
After adopting technique scheme; Compare with traditional structure; The electroacoustic transducer vibrating diaphragm of the utility model has the basement membrane of at least one strata ether ether ketone material and one deck binder course at least; This structure can improve the intensity of vibrating diaphragm significantly, improves the stability of product, can be used for the large power, electrically sonic transducer.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed description.
As shown in Figure 1, the utility model electroacoustic transducer involving vibrations system, magnetic circuit system and accommodate the fixedly auxiliary system of vibrational system and magnetic circuit system.Vibrational system comprises vibrating diaphragm 21 and the voice coil loudspeaker voice coil 22 that is incorporated into vibrating diaphragm 21 downsides, and in the course of work, voice coil loudspeaker voice coil 22 receives the control of alternating signal to drive the motion that vibrating diaphragm 21 produces alternation; Magnetic circuit system comprises washer 31, magnet 32 and the basin frame 33 that combines successively; Shell 12 is accommodated fixedly vibrational system and magnetic circuit system, and protecgulum 11 lids are connected on the shell 12, protecgulum 11 and the shell 12 common protection frameworks that form electroacoustic transducer.
Fig. 2 is the enlarged diagram of A part diaphragm structure shown in Figure 1, and is as shown in Figure 2, and vibrating diaphragm 21 comprises vibrating diaphragm basement membrane 211 and the binder course 212 that combines with basement membrane 211, and wherein, the utility model basement membrane 211 adopts polyether-ether-ketone (PEEK) material.Polyetheretherketonematerials materials has rigidity and flexibility, and particularly the fatigue resistance under alternate stress is very outstanding, and hot strength is bigger.Based on above-mentioned characteristic, adopt the vibrating diaphragm 21 of this polyetheretherketonematerials materials can improve the bulk strength of vibrating diaphragm 21, prolong the useful life of vibrating diaphragm 21, thereby improve the stability of product; Because intensity is bigger, can be applied in the large power, electrically sonic transducer, difficult generation breakages etc. are bad.
In this implementation process, binder course 212 adopts polyurethane (PU) material, and binder course 212 combines with basement membrane 211 hot pressing; Can be incorporated into the upside and/or the downside of basement membrane 211; Preferably, the binder course 212 of polyurethane material is incorporated into the upside of basement membrane 211, so that technological operation.
Fig. 3 is a kind of local enlarged diagram of improved diaphragm structure, and is as shown in Figure 3, and vibrating diaphragm 21 ' has two-layer basement membrane: basement membrane 211a ' and basement membrane 211b ', wherein basement membrane 211a ' and basement membrane 211b ' all adopt polyetheretherketonematerials materials.Binder course 212 ' between basement membrane 211a ' and the basement membrane 211b ' is a glue-line, and the binder course 212 ' of structural adhesive layer is with basement membrane 211a ' and basement membrane 211b ' adhesive bond.
In addition, binder course 212 ' also can adopt polyurethane material, can the binder course 212 ' of polyurethane material be fixed with basement membrane 211a ' and basement membrane 211b ' hot pressing.
The vibrating diaphragm 21 ' of the two-layer polyetheretherketonematerials materials basement membrane of this employing can further increase the bulk strength of vibrating diaphragm 21 '.
Except that above-mentioned execution mode, the basement membrane of the utility model can be more than two-layer, is being provided with the binder course of glue-line or polyurethane material arbitrarily between the two-layer basement membrane; In addition, can be provided with or not be provided with the binder course of polyurethane material at the upside of the superiors' basement membrane, also can be provided with or not be provided with the binder course of polyurethane material at the downside of orlop basement membrane, these improve the enforcement that does not all influence the utility model.
In addition, in order to promote the high frequency characteristics of vibrating diaphragm, also can on vibrating diaphragm, combine the composite bed of rigidity.
Under the above-mentioned instruction of the utility model; Those skilled in the art can be in his improvement of the basic enterprising Xingqi of the foregoing description and distortion; And these improvement and distortion all drop in the protection range of the utility model, and those skilled in the art should be understood that; Above-mentioned specific descriptions are just better explained the purpose of the utility model, and the protection range of the utility model is limited claim and equivalent thereof.
