End is connect with interior interconnecting piece.Interior interconnecting piece is provided with the thinning part 14 of annular.
For example, thinning part 14 is bonded between vibrating diaphragm 11 and the first end 18 of voice coil 17.In the upper and lower surfaces of interior interconnecting piece
Material is gone to handle, to form thinning part 14.
Flexible connector 13 is structure as a whole.The interior interconnecting piece and outer interconnecting piece 15 of annular make setting for flexible connector 13
It sets and becomes easy.
In other examples, as seen in figs. 5-6, flexible connector 13 is provided at least two, and is connected and fixed on sound
The first end 18 of circle 17.For example, interior interconnecting piece and outer interconnecting piece 15 are linear in being parallel to each other.Cantilever 16 be located at interior interconnecting piece and
Between outer interconnecting piece 15.Optionally, the shape of cantilever 16 is S-shaped, U-shaped, continuous bent etc., and those skilled in the art can be with
It is selected according to actual needs.Thinning part is bonded in the first end 18 of voice coil 17.
Preferably, cantilever 16 is U-shaped structure.The open end of the cantilever 16 of two U-shapeds is opposite or is disposed opposite to each other.It is this to set
Mode is set, the elasticity of cantilever 16 is more balanced, and the structural strength of flexible connector 13 is higher.
In this example embodiment, flexible connector 13 is split type structure.This mode can save the material of flexible connector 13
Expect dosage.
In other examples, flexible connector also can connect the second end 19 for being fixed on voice coil 17, as shown in Figure 8.
Preferably, multiple flexible connectors 13 have different damped coefficients.Under the frequency range of setting, vibration component is not
Amplitude with position is different.It is big in the damped coefficient of the flexible connector 13 at the big position of amplitude, at the small position of amplitude
Flexible connector 13 damped coefficient it is small.In this way, vibration component can be more efficiently prevented to polarize.
In one example, flexible connector 13 is set as two, and is symmetrically dispersed in around voice coil 17.Sound
The entirety of circle 17 is rectangle structure.It is two long to be symmetrically arranged at the voice coil of rectangle structure for two flexible connectors 13
Axis side or two short axle sides.Long axis side refers to two parallel with the long axis side of rectangle structure.Short axle side refer to it is short
Two parallel sides of axis.The thinning part 14 of two flexible connectors 13 is bonded in the first end 18 or of voice coil 17 respectively
Two ends 19.This setup can be effectively reduced the polarization of vibration component.
In one example, the entirety of voice coil 17 is rectangle structure.Flexible connector 13 is four and is respectively set
On four angles of rectangle structure or on four edges.This setup can equally be effectively reduced the inclined of vibration component
Vibration.
In one example, flexible connector 13 is multiple and is evenly distributed in around voice coil 17.Wherein, one
Flexible connector 13 includes substrate sandwich layer 27, conductor layer 28 and the coating layer 29 being combined with each other.Substrate sandwich layer 27, conductor layer
28 and coating layer 29 material and set-up mode it is as previously described.Glue-line can also be set between conductor layer 28 and coating layer 29
30.Conductor layer 28 and coating layer 29 are removed, on interior interconnecting piece to form thinning part.Voice coil 17 passes through conductor layer 28 and external electrical
Road conducting.
Other flexible connectors 13 are insulation.For example, other flexible connectors 13 are formed by plastic production.It is preferred that
Ground is combined by a variety of plastic layers.Material is gone to handle in interior interconnecting piece, to form thinning part 14.
In this way, one of flexible connector 13 has the function of conducting, other flexible connectors 13 are insulation, from
And the dosage of conductor material is saved.
