The utility model provides a kind of loudspeaker, in some embodiments, with reference to Fig. 1-3, including bracket 1 and is fixed on
Vibrating diaphragm on bracket 1.Vibrating diaphragm includes fixed part 2 and ring portion 3.There is the loading end 11 for carrying fixed part 2 on bracket 1.
Fixed part 22 is fixed on loading end 11, such as is fixed by modes such as bonding, ultrasounds, and vibrating diaphragm is fixed on bracket 1.Ring
The section in portion 3 is arc structure.Ring portion 3 makes vibrating diaphragm be able to maintain axis in vibration for supporting and keeping vibration vibration of membrane
To movement, and it is unable to transverse movement.It ring portion 3 can be using materials systems such as fiber+composite coating material, rubber, Foamexes
At.The outside of vibrating diaphragm is arranged in around ring portion 3 for fixed part 2.Ring portion 3 is connect with fixed part 2, and ring portion 3 passes through fixed part 2
It is fixed in bracket 1.
The outside of loading end 11 is provided with outer edge 12 on bracket 1.Outer edge 12 is higher than loading end 11.Outer edge 12 is used
Bracket 1 and the other structures in speaker be connected and fixed in assembly.Not higher than outer when fixed part 2 is fixed on loading end 11
Edge 12, can be concordant with outer edge 12 or lower than outer edge 12.During assembling loudspeaker, wherein outer edge 12 with
When other structures cooperate, higher outer edge 12 enables to have an impact fixed part 2 when fixed, when reducing assembly
The risk for causing fixed part 2 to deform and influencing speaker acoustical behavior is squeezed on fixed part 2.
One end of fixed part 2 is connect with ring portion 3.The other end of fixed part 2 is close to outer edge 12 and raises upward, protrusion
Height be also no more than outer edge 12.In some cases, outer edge 12 is higher than the height of loading end 11 much higher than common solid
The thickness in portion 2 is determined, for example, fixed part 2 and the material thickness in ring portion 3 are 0.4mm or so, the height that ring portion 4 arches upward upwards
Degree is about 3mm, and highest point when in order to guarantee that ring portion 3 vibrates is higher than the height of loading end 11 without departing from loudspeaker, outer edge 12
Degree is about 3.0mm, at this point, side may be formed between one with other structures thereon after fixed part 2 reassembles on loading end 11
Gap, or it is the cavity of lateral open;Due to this gap presence and product test when microphone have with the monomer in mould group
Certain directive property, so that the frequency response curve of product will affect the acoustical behavior of product there are an apparent high frequency paddy.Pass through
One end of the close outer edge 12 of fixed part 2 raises upward, such as one end of fixed part 2 raises upward 2.4mm-2.6mm or so,
Filling reduces gap to reduce its brought high frequency paddy, guarantees the acoustical behavior of product after assembly.
The wind that causes vibrating diaphragm deformation is squeezed the fixed part of vibrating diaphragm in vibrating diaphragm component when the utility model can reduce assembly
Danger guarantees product acoustical behavior and product yield.Furthermore it is possible to reduce brought by outer edge increases in frequency response curve
The influence of high frequency paddy.
In some embodiments, with reference to Fig. 2, outer edge 12 extends to the outside of bracket 1, is and the other structures in speaker
Sufficiently large mounting area is provided when assembling cooperation;On the other hand, outer edge 12 to the outside of bracket 1 extend can enhance outside
Edge 12 can reduce the risk of the deformation of bracket 1 when accident occurring falling in the intensity of in-plane.
In some embodiments, with reference to Fig. 2, outer edge 12 has the bending part 13 bent downward far from the side of bracket 1,
The structural strength for increasing outer edge 12 is bent by edge, further, and increases the framework intensity of bracket 1, it is anti-to increase it
Fall the performance of deformation.
In some embodiments, with reference to Fig. 3, it is provided with fixation hole 14 on outer edge 12, for will be in bracket 1 and speaker
Other structures assembly connection.Further, fixation hole 14 can be used for being cooperatively connected with structures such as screw, positioning columns.
In some embodiments, with reference to Fig. 3, multiple interconnecting pieces 15 stretched out outward are symmetrically arranged on outer edge 12,
Fixation hole 14 is arranged on interconnecting piece 15.In the enough situations of intensity, the setting due to fixation hole 14 is reduced so that bracket 1
Overall volume integrally increases, and reduces its requirement to assembly space, space is saved, convenient for the Miniaturization Design of loudspeaker.
In some embodiments, with reference to Fig. 2, fixed part 2 can be made up with ring portion 3 of integral forming process.Into one
Step, it can be using the materials integrated injection molding such as rubber or silica gel.
In some embodiments, with reference to Fig. 1 and Fig. 3, bracket 1 can be the frame in cone basin formula loudspeaker.With reference to Fig. 1,
Vibrating diaphragm can also include the cone basin in the middle part of vibrating diaphragm and being connected in ring portion 3, and the dust cap etc. of covering closing voice coil
Structure, collectively constitutes a vibrating diaphragm, and vibrating diaphragm, being capable of external sounding in vibration.In this field other kinds of loudspeaker and
Other common knowledges also repeat no more herein.
Other side according to the present utility model, the utility model also provide a kind of speaker, including shell and above-mentioned
Loudspeaker, loudspeaker are arranged in shell, and vibrating diaphragm is by vibrating external sounding.
It in some embodiments, further include gasket seal 4 with reference to Fig. 1-3.Gasket seal 4 is fixed on outer edge 12, is made
Obtaining bracket 1 can be tightly connected when connecting with the other structures in speaker, prevent the poorly sealed acoustics for causing to influence speaker
Performance.The gasket seal 4 can be made of materials such as foam, rubber, can achieve the effect that sealing, the application couple
This is not intended to limit.
In some embodiments, with reference to Fig. 3, gasket seal 4 is hollow structure and is covered on outer edge 12, avoids vibrating diaphragm
Oscillating component, do not hinder the external transmitting of the vibration sounding and sound of vibrating diaphragm.
In some embodiments, with reference to Fig. 2, gasket seal 4 extends to 1 interior direction of bracket.Fixed part 2 is close to outer edge
12 one end raises upward close or abuts gasket seal 4, and gasket seal 4 does not surpass to the inner ring surface of 1 interior direction of bracket
The inner wall 21 that fixed part 2 convexes to form is crossed, prevents fixed part and top structure from forming height existing for frequency response curve caused by gap
Frequency paddy guarantees the acoustical behavior of speaker.
Although being described in detail by some specific embodiments of the example to the utility model, this field
It is to be understood by the skilled artisans that above example merely to be illustrated, rather than in order to limit the scope of the utility model.This
Field it is to be understood by the skilled artisans that can not depart from the scope of the utility model and spirit in the case where, to above embodiments
