Phonation unit abbreviation unit refers to the loudspeaker that loud speaker is commonly called as on electroacoustic techniques.Loud speaker is as a kind of energy
The device for enough converting electrical energy into acoustic energy has been widely used in the mobile terminal apparatus such as mobile phone, computer.Along with science skill
The rapid exhibition of art and electronics industry, people also proposed increasingly higher demands for the performance of speaker product.
Currently, phonation unit generally use screen cloth, adjustable sound paper or metal screen on the market presses down to adjust air mass flow
The dynamic of sound film processed.However, overstocked longitude and latitude gap can allow the sound film Oscillation Amplitude of phonation unit to reduce, and then low frequency is caused to rise
Point is low, and sense of hearing is jerky.And excessively thin longitude and latitude can then allow phonation unit undue oscillation, then sound film beat, voice coil can be caused to shake different
The problems such as sound.
Utility model content
For this purpose, the purpose of this utility model is to provide a kind of phonation unit with active air damping structure sound film,
To solve the problems, such as that current phonation unit low frequency starting point is low, sense of hearing is jerky, sound film beat, voice coil shake abnormal sound.
To achieve the above object, the utility model mainly use following technical scheme for：
A kind of phonation unit with active air damping structure sound film comprising sound film, holder and elastic interlayer, it is described
Sound film includes top dome and the ring for being set to top dome outboard peripheries, and sticking part, the ring are equipped between the ring and top dome
Outer side edges along be equipped with outside sticking part；The outer surface of the holder is equipped with outside mounting portion, is set on the medial surface of holder
There is inside mounting portion；The outside sticking part of the ring is installed on the outside mounting portion of holder；One end of the elastic interlayer
It is installed on the inside mounting portion of holder, the middle part or end side upper surface of elastic interlayer fit in the bottom of sound film sticking part
On face；Seal chamber is formed between the sound film, holder and elastic interlayer.
Further, the sound film further includes interconnecting piece, and the interconnecting piece is set on the neighboring of the top dome, should
Interconnecting piece is connected to top dome and ring.
Further, the interconnecting piece is extended from top dome to ring direction in bottom-up, and interconnecting piece is in evagination
Arc setting.
Further, the sticking part is set between the interconnecting piece and top dome portion of the sound film, the bottom surface of the sticking part
In horizontally disposed.
Further, the L-shaped setting of outside sticking part of the sound film ring, the outside mounting portion of the holder are equipped with
Limited step, the outside sticking part are installed on limited step.
In conclusion the utility model is by being arranged sound film, holder and elastic interlayer, the sound film, holder and elastic clip
Interlayer is formed with seal chamber, and when sound film vibrates, the air in seal chamber is compressed, since seal chamber is sealed set so that sound
Film can quickly restPose, so as to avoid sound film too low or excessively high problem of sound film Oscillation Amplitude caused by deformation,
And then the generation for the problem of avoiding jerky phonation unit sense of hearing, beat, abnormal sound.The utility model it is highly practical, have compared with
Strong dissemination.
Description of the drawings
Fig. 1 is the cross-section structure signal of the embodiment for the phonation unit that this practicality has active air damping structure sound film
Figure.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in Figure 1, the utility model provides a kind of phonation unit with active air damping structure sound film, the tool
It includes sound film 10, holder 20 and elastic interlayer 30, the sound film 10, holder to have the phonation unit of active air damping structure sound film
Seal chamber 40 is enclosed between 20 and elastic interlayer 30, the seal chamber 40 can play the role of active air damping.
The sound film 10 includes top dome 11, interconnecting piece 12 and ring 13, and the interconnecting piece 12 is set to 11 outer periphery of top dome
On edge, the ring 13 is set on the neighboring of interconnecting piece 12, which is connected to top dome 11 and ring 13.It is described
Interconnecting piece 12 is extended from top dome 11 to 13 direction of ring in bottom-up, and interconnecting piece 12 is convexly curved setting.Institute
The outer ledge for stating ring 13 is equipped with sticking part 15 on the outside of ring, and in the present embodiment, the outside sticking part 15 is L-shaped to be set
It sets.The side of the ring 13 being connected with interconnecting piece 12 is equipped with inside sticking part 14,14 side of inside sticking part
Ring 13 is arc-shaped setting.In addition, a sticking part 16 is equipped between the top dome 11 and interconnecting piece 12, the sticking part 16
Bottom is connected on the elastic interlayer 30.
