Abstract
The utility model discloses an acoustic metal vibrating diaphragm including a vibrating-diaphragm substrate and a metal clad layer. The surface of the vibrating-diaphragm substrate is covered with the metal clad layer, which is made of a pure-beryllium or a beryllium alloy material and thus the metal clad layer is formed through evaporating the pure-beryllium or the beryllium alloy material on the surface of the vibrating-diaphragm substrate. Thus, through use of the metal clad layer, rigidness of the vibrating-diaphragm substrate is increased and flexibility of the vibrating-diaphragm substrate is also maintained. Moreover, frequency band is wide so that a high-frequency problem can be well solved and bettering of a tone quality is facilitated. The acoustic metal vibrating diaphragm can be widely applied in different acoustic devices such as earphones, ear plugs, loudspeakers and microphones and the like.
Description
Technical field
The utility model relates to vibrating diaphragm art, refers in particular to a kind of acoustics metal vibration diaphragm.
Background technology
Vibrating diaphragm is between the important composition parts of the various acoustic equipments such as earplug, earphone, microphone, existing vibrating diaphragm normally adopts a kind of forming materials to go out the vibrating diaphragm of simple layer, when sounding, acoustic equipment conventionally has high and low frequency, in order to solve the high frequency problem of acoustic equipment, traditional solution is, stamp on vibrating diaphragm, to strengthen the rigidity of vibrating diaphragm, yet, list can not make the pliability of vibrating diaphragm and rigidity take into account preferably with this kind of method, thereby make the frequency response of acoustic equipment wide not, tonequality is good not.
Utility model content
In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of acoustics metal vibration diaphragm, and it can effectively solve existing vibrating diaphragm and adopt stamp mode can not keep vibrating diaphragm pliability and make the imperfect problem of acoustic equipment tonequality.
For achieving the above object, the utility model adopts following technical scheme:
A metal vibration diaphragm, includes shaking membrane substrate and the coat of metal, and this coat of metal is covered on the surface of shaking membrane substrate, and this coat of metal is pure beryllium or beryllium alloy material.
As a kind of preferred version, described shaking membrane substrate is film.
As a kind of preferred version, further include copper ring, the outer rim of this shaking membrane substrate is all connected with the inner edge of this copper ring with the outer rim of the coat of metal.
As a kind of preferred version, the cross section of described copper ring is square.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly, and as shown from the above technical solution:
By adopting pure beryllium or beryllium alloy material evaporation on the surface of shaking membrane substrate to form the coat of metal, so, utilize this coat of metal both to increase the rigidity of shaking membrane substrate, the pliability that has kept again shaking membrane substrate, and bandwidth, can solve well high frequency problem, thereby be conducive to make tonequality better, be widely used in the various acoustic equipments such as earphone, earplug, loudspeaker, microphone.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is the vertical view of the preferred embodiment of the utility model;
Fig. 2 is the sectional view of the preferred embodiment of the utility model.
Accompanying drawing identifier declaration:
10, shaking membrane substrate 20, the coat of metal
30, copper ring.
Embodiment
Please refer to shown in Fig. 1 and Fig. 2, the concrete structure that it has demonstrated the preferred embodiment of the utility model, includes shaking membrane substrate 10 and the coat of metal 20.
This shaking membrane substrate 10 is film.This coat of metal 20 is covered on the surface of shaking membrane substrate 10, at this coat of metal 20, be pure beryllium or beryllium alloy material, in the present embodiment, that mode by metal evaporation forms aforementioned metal coating 20 in the surface coverage of shaking membrane substrate 10, so can increase the rigidity of shaking membrane substrate 10, keep again the pliability of shaking membrane substrate 10.
And, in the present embodiment, further including copper ring 30, the cross section of this copper ring 30 is square, and the outer rim of the outer rim of this shaking membrane substrate 10 and the coat of metal 20 is all connected with the inner edge of this copper ring 30.
Design focal point of the present utility model is: by adopting pure beryllium or beryllium alloy material evaporation on the surface of shaking membrane substrate to form the coat of metal, so, utilize this coat of metal both to increase the rigidity of shaking membrane substrate, the pliability that has kept again shaking membrane substrate, and bandwidth, can solve well high frequency problem, thereby be conducive to make tonequality better, be widely used in the various acoustic equipments such as earphone, earplug, loudspeaker, microphone.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
