Abstract
The utility model discloses a strip-type groove array vibrating diaphragm applied to a sounder. The strip-type groove array vibrating diaphragm applied to the sounder comprises a flat spherical top, R edges extending outward from the spherical top, and a glue line for bonding the flat spherical top with the R edges. The flat spherical top is formed by a single layer material, and the flat spherical top is provided with strip-shaped grooves. According to the utility model, the spherical top of the vibrating diaphragm is a single layer diaphragm, and is relatively light in weight, the integral sensitivity of the sounder can be increased, the strip-shaped grooves serve as reinforcing ribs, the integral rigidity of the spherical top is improved, and medium high frequency characteristics of the sounder can be improved.
Description
Technical field
The utility model relates to a kind of acoustical generator vibrating diaphragm, relates in particular to the bar-shaped trough array diaphragm structure of acoustical generator.
Background technology
Various audio frequency and video, communication equipment, the portable electric appts such as portable computer are always with fast speed development, and it is functional more and more stronger, particularly the generally use of smart mobile phone in recent years, people constantly pursue excellent tonequality, thereby also more and more higher to the quality requirements of minitype acoustic generator.
The features such as current acoustical generator generally uses composite diaphragm, and it is low that it has resonance frequency, bandwidth, auditory perception shows as soft, the clear exquisiteness of tonequality.
The composite diaphragm of prior art is comprised of hard compound slab ball top and R limit, and described ball pushes up and formed by two or more Material cladding, its again with the bonding formation composite diaphragm in R limit.Yet the quality on ball top directly affects the medium-high frequency quality of product, its rigidity not by force medium-high frequency lack, show as product tonequality dry.Use compound dull and stereotyped ball top, can promote medium-high frequency characteristic, but product sensitivity is not high, because ball top is composited by multiple material, quality is hard, has increased the quality of product vibrational system.
Summary of the invention
The purpose of this utility model is to provide the vibrating diaphragm of the improving product sensitivity of a kind of energy and high frequency characteristic.
The purpose of this utility model is achieved through the following technical solutions:
A bar-shaped trough array vibrating diaphragm for acoustical generator, comprises dull and stereotyped ball top, from ball, pushes up outward extending R limit and the glue-line on bond dull and stereotyped ball top and R limit, and dull and stereotyped ball top is monolayer material, and dull and stereotyped ball has bar-shaped trough on top.
In order to obtain better technique effect, described dull and stereotyped ball is distributed with two above bar-shaped trough arrays on top; Described bar-shaped trough becomes circular arc projection or depression; Described dull and stereotyped ball top is strip; Described dull and stereotyped ball top is rectangle or racetrack.
The utility model is applied on acoustical generator, and the utility model is contained in acoustical generator, and up-down vibration is sounded.Compare with the vibrating diaphragm of correlation technique, the dull and stereotyped ball of the utility model top is monolayer material, and a plurality of bar-shaped troughs of array distribution, can promote sensitivity and the medium-high frequency characteristic of acoustical generator, thereby make product obtain excellent tonequality.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment schematic diagram;
Fig. 2 is the utility model embodiment three-dimensional exploded view.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
A bar-shaped trough array vibrating diaphragm for acoustical generator, comprises dull and stereotyped ball top 1, from ball, pushes up outward extending R limit 2 and the glue-line 3 on bond dull and stereotyped ball top and R limit, and dull and stereotyped ball top 1 is monolayer material, has two above bar-shaped trough 11 arrays on dull and stereotyped ball top 1; The exterior annular horizontal edge 12 on dull and stereotyped ball top 1 is bonded together by glue-line 3 with the interior annular plane 21 on R limit 2, forms composite diaphragm.11 one-tenth circular arc projections of bar-shaped trough or depression; Dull and stereotyped ball top 1 is one or more combinations in strip, rectangle or racetrack.
Above-mentioned bar-shaped trough array vibrating diaphragm is applied on acoustical generator, and bar-shaped trough array vibrating diaphragm is contained in acoustical generator, and dull and stereotyped ball top 1 and R limit 2 up-down vibration are sounded.Compare with the vibrating diaphragm of correlation technique, the dull and stereotyped ball of the utility model top is monolayer material, and a plurality of bar-shaped troughs of array distribution, can promote sensitivity and the medium-high frequency characteristic of acoustical generator, thereby make product obtain excellent tonequality.
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 the equivalence that those of ordinary skills do according to disclosed content is modified or is changed, and all should include in the protection range of recording in claims.
