Description
Technical field
The utility model relates to electro-acoustic product technical fields, and in particular to a kind of diaphragm of loudspeaker.
Background technique
With the expansion in consumer electronics market, the consumer electronics products such as a large amount of mobile phones, laptop are obtained extensively
Using as acoustic element important in consumer electronics product, loudspeaker has extensive demand, as people are to consumer
The requirement of electronic product improves, and speaker performance also increasingly receives the concern of people, as the sound-generating element of speaker unit,
The diaphragm of loudspeaker directly affects the acoustical behavior of loudspeaker.
The diaphragm of loudspeaker of traditional structure is driven by the loudspeaker voice coil in magnetic field, when loudspeaker voice coil
When being powered in coil, the diaphragm of loudspeaker can vibrate in magnetic field with loudspeaker voice coil, generation acoustic pressure, but this " film " formula
The shortcomings that vibration, is that the vibration of the diaphragm of loudspeaker is asynchronous with driving signal, and diaphragm oscillations are unstable, and there are distortion phenomenons.
Utility model content
The utility model in view of the above problems, provides a kind of diaphragm of loudspeaker, can be improved diaphragm of loudspeaker vibration
Dynamic stability reduces distortion.
The utility model to achieve the above object, takes following technical scheme to be achieved:
A kind of diaphragm of loudspeaker, including vibrating diaphragm main body, fixed bracket, voice coil, aluminium flake, the vibrating diaphragm main body are equipped with dragon
Bone, the keel radially distribute around from the center of vibrating diaphragm main body, and the vibrating diaphragm body peripheral edge is equipped with outstanding side, described solid
Fixed rack and the front on the outstanding side are fitted and connected, and the aluminium flake and the back side on the outstanding side are fitted and connected, and the voice coil is fixed
It is connected to the back side on the outstanding side and the position of vibrating diaphragm main body handover.
Preferably, the front on the outstanding side is the convex surface of the vibrating diaphragm main body, and the back side on the outstanding side is the vibrating diaphragm master
The concave surface of body, the keel are respectively provided at the convex surface and concave surface of the vibrating diaphragm main body.
Preferably, the shape of the vibrating diaphragm main body is top dome shape, and the outstanding side is annular.
Preferably, multiple folds are intervally distributed on the inside of the outstanding side.
Preferably, opposite on the fixed bracket to be equipped with positive electrode interface and negative electrode interface, the positive electrode interface with
The positive electrode lead of the voice coil connects, and the negative electrode interface is connect with the negative electrode lead of the voice coil.
The working principle of the utility model is as follows: positive electrode interface and negative electrode interface on fixed bracket, which are powered, to be generated
Magnetic field, so that voice coil conduction is vibrated and vibrating diaphragm is driven to carry out vibration sounding.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model structure is simple, by the keel being arranged in vibrating diaphragm main body, can be improved diaphragm of loudspeaker vibration
Stability, reduce distortion；The stemness of vibrating diaphragm can be enhanced in setting fold on the inside of outstanding side, is conducive to improve vibration vibration of membrane frequency
Rate.
Detailed description of the invention
Fig. 1 is a kind of convex configuration schematic diagram of diaphragm of loudspeaker of the utility model；
Fig. 2 is a kind of concave structure schematic diagram of diaphragm of loudspeaker of the utility model.
Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing.
Referring to FIG. 1 to FIG. 2, a kind of diaphragm of loudspeaker, including vibrating diaphragm main body 1, fixed bracket 2, voice coil 3, aluminium flake 4, vibrating diaphragm
Main body 1 is equipped with keel 10, and keel 10 radially distribute around from the center of vibrating diaphragm main body 1, can uniformly divide in this way
The vibration of driving signal bring is dissipated, so that vibration vibration of membrane is more stable, 1 periphery of vibrating diaphragm main body is equipped with outstanding side 5, is hanging side 5 just
Face is the convex surface of vibrating diaphragm main body 1, and the back side for hanging side 5 is the concave surface of vibrating diaphragm main body 1, and keel 10 are respectively provided at the convex of vibrating diaphragm main body 1
Face and concave surface, fixed bracket 2 and the front on outstanding side 5 are fitted and connected, and aluminium flake 4 and the back side on outstanding side 5 are fitted and connected, and voice coil 3 is fixed
The position that the back side and vibrating diaphragm main body 1 for being connected to outstanding side 5 join.
In the present embodiment, the shape of vibrating diaphragm main body 1 is top dome shape, the sound that the vibration of sound film can in this way issued more added with
Cohesion, sound quality is more preferable, hangs side 5 for annular, fixed bracket 2 is annular, and the radius on the outstanding side of support bracket fastened radius ratio is small.
In order to improve the vibration frequency of vibrating diaphragm, multiple folds 51 can be spaced apart to enhance vibrating diaphragm in the inside on outstanding side 5
Stemness.
It is opposite on fixed bracket 2 to be equipped with positive electrode interface 21 and negative electrode interface 22, positive electrode interface 21 in the present embodiment
It is connect with the positive electrode lead of voice coil 3, negative electrode interface 22 is connect with the negative electrode lead of voice coil 3.In above structure, in fixation
When the positive electrode interface and negative electrode interface of bracket are powered, voice coil conduction will be vibrated simultaneously, and drive vibrating diaphragm main body
It is vibrated.
The working principle of the utility model is as follows: positive electrode interface and negative electrode interface on fixed bracket, which are powered, to be generated
Magnetic field, so that voice coil conduction is vibrated and vibrating diaphragm is driven to carry out vibration sounding.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model structure is simple, by the keel being arranged in vibrating diaphragm main body, can be improved diaphragm of loudspeaker vibration
Stability, reduce distortion；The stemness of vibrating diaphragm can be enhanced in setting fold on the inside of outstanding side, is conducive to improve vibration vibration of membrane frequency
Rate.
Only as described above, the only preferred embodiment of the utility model, when the utility model cannot be limited with this
The range of implementation, i.e., generally according to simple made by content documented by the utility model claims and utility model specification
Equivalent changes and modifications all still belong within the utility model claims scope.In addition, abstract part and title are only
For assisting patent document search to be used, not it is used to limit the interest field of the utility model.
