Abstract
The utility model discloses a mini-acoustic generator diaphragm, which comprises a folding portion in an annular hollow structure and a globe top. The globe top is combined onto a hollow portion of the folding portion and closely combined with the folding portion; and a groove is arranged on the globe top. As the groove is arranged on the globe ball portion of the diaphragm, combination and assembly of the globe top and the folding portion of the mini-acoustic generator diaphragm are favorable for fixing of the globe top and positioning and mounting of the folding portion, thereby simplifying production process, and lowering production cost. Simultaneously, the design increases rigidness of the globe top of the diaphragm, and can restrain lack of fidelity caused by high-frequency cutting vibration.
Description
Technical field
The utility model relates to a kind of minitype acoustic generator vibrating diaphragm, more particularly, relates to and a kind ofly helps the ball top can combine fixedly with kink at the ball top of minitype acoustic generator vibrating diaphragm the time and fix, so that the minitype acoustic generator vibrating diaphragm that combines with kink.
Background technology
Along with the development in portable consumer electronic product market, a large amount of microphone device particularly moving-coil type acoustical generator has obtained using widely.As everyone knows, the moving-coil type acoustical generator is by voice coil loudspeaker voice coil stressed in the magnetic gap that is produced by magnet, drives vibrating diaphragm and sounds along the vertical direction vibration.Vibrating diaphragm is structure as a whole in the traditional structure, can't take into account the high and low frequency performance of vibrating diaphragm simultaneously, is unfavorable for the improvement of acoustical behavior.In improvement, can adopt following scheme to improve to above-mentioned conventional art:
In the improvement project, (1) is to adopt the bigger material of rigidity to replace original monomer vibrating diaphragm by the core with the vibrating diaphragm body; (2) be that vibrating diaphragm is set to split-type structural.Plant to improve for aforesaid (2), its known design as shown in Figure 4, rectangular vibrating diaphragm comprises the rectangle kink 1 and the ball top 2 of annular and hollow, wherein ball top 2 is bonded and fixed on the kink 1, and sealing and fixing.
Though above-mentioned improvement project has been improved the defective that the monomer vibrating diaphragm of traditional structure exists, this design, particularly in microminiaturized product, ball top 2 inconvenient with kink 1 location and installation, producting process difficulty is comparatively complicated, is unfavorable for the reduction of production cost.
So be necessary the diaphragm structure of above-mentioned traditional structure is further improved, to avoid above-mentioned defective.
The utility model content
Technical problem to be solved in the utility model provides a kind of minitype acoustic generator vibrating diaphragm, in the time of can combining fixedly with kink at the ball top of minitype acoustic generator vibrating diaphragm, help the ball top and fix so that with the combining of kink.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of minitype acoustic generator vibrating diaphragm, comprise kink, and described kink is the hollow structure of annular; The ball top, described ball top is combined on the hollow space of described kink, and combines with described kink is airtight; And: described ball top is provided with groove.
Optimized technical scheme is that described vibrating diaphragm is a rectangle structure.
Optimized technical scheme is that described groove is positioned at the center at described ball top.
Optimized technical scheme is that described ball top and described kink gummed are fixing.
Optimized technical scheme is that described groove is an elongate structure.
Owing to adopted technique scheme, a kind of minitype acoustic generator vibrating diaphragm comprises kink, and described kink is the hollow structure of annular; The ball top, described ball top is combined on the hollow space of described kink, and combines with described kink is airtight; And: described ball top is provided with groove; Owing on the ball top of vibrating diaphragm, be provided with groove, in the time of can combining assembling at the ball top of minitype acoustic generator vibrating diaphragm with kink, help the fixing of ball top, and and the location and the installation of kink, simplified production technology, reduced production cost; This design has simultaneously increased the rigidity at vibrating diaphragm ball top, can suppress high frequency and cut apart the distortion that vibration brings.

Embodiment
Below, describe preferred embodiment of the present utility model in conjunction with the accompanying drawings in detail.
In the following detailed description, only some one exemplary embodiment of the present utility model has been described by the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, can revise described embodiment with various mode and do not depart from spirit and scope of the present utility model.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection range of claim.In addition, in this manual, identical Reference numeral is represented identical part.
Fig. 1 is the stereogram of the utility model embodiment vibrating diaphragm, and Fig. 2 is the stereogram at the utility model embodiment vibrating diaphragm ball top, and Fig. 3 is the profile of the utility model embodiment vibrating diaphragm.As depicted in figs. 1 and 2, described vibrating diaphragm is a rectangle structure, comprise kink 1 and with the kink 1 airtight ball top 2 that combines, kink 1 is a loop configuration, and the center of kink 1 is a hollow structure; Ball top 2 is the material formation of hardness greater than kink 1, can be plastic construction, is provided with groove 3 at the center at ball top 2, and groove 3 is an elongate structure, and its size is by default; At the ball top 2 with kink 1 when being fitted to each other, can make in the groove 3 that ball top 2 is fixing by frock is put into, thereby make ball top 2 and kink 1 corresponding combination.
In embodiment of the present utility model, the shape of vibrating diaphragm can also be other shapes such as circle, ellipse except described rectangle.In addition, groove also can preferably adopt can be so that other fixing shape, also can not make up and does not depart from the spirit and scope of determined the invention in the dependent claims above-mentioned ball top and kink different structure.
