Gap 24 between the wing 22 is connected, therefore the film can also be considered as and block gap 24.The film can bridge at oscillating airfoil 22
Gap 24 is covered between framework 21, it is to be understood that the film positioned at the framework 21 of the both sides of gap 24 and will can shake
The dynamic wing 22 is bridged, so that the gap 24 is covered into closure.Specifically, film can be covered in whole framework 21 and oscillating airfoil 22
On.
In this embodiment, the film allows the oscillating airfoil 22 to be moved relative to the framework 21.Specifically, should
Film can be elastic membrane, and the film can produce the deformation such as stretching, and the film in motion of oscillating airfoil 22 is stretched, and holding pair
The covering closure in gap.Feasible in addition, film can also leave appropriate allowance in the position of gap 24, so that in oscillating airfoil 22
Ensure that oscillating airfoil 22 is not disturbed during vibration by allowance.
In the present embodiment, oscillating airfoil 22 is by the connection framework 21 of hinge 23, and framework 21 can be fixed on housing 10,
So as to which the position of vibrating diaphragm 20 be fixed.Oscillating airfoil 22 can be moved by hinge 23 relative to framework 21.Specifically, hinge 23 can be with
Bent when being moved by oscillating airfoil 22, so that the formation vibration of oscillating airfoil 22.In further embodiment, hinge 23 can also have pivot
Rotating shaft, the pivotal axis can be parallel with the width of oscillating airfoil 22, and oscillating airfoil 22 can surround the pivot axis, its rotation side
To perpendicular to the pivotal axis.
It is preferred that an embodiment in, the hinge 23 can with oscillating airfoil 22, framework 21 be integral type structure, i.e. the vibrating diaphragm
20 do not have film when structure (oscillating airfoil 22, framework 21, hinge 23) can be formed in one structure.Now, oscillating airfoil 22,
Framework 21, hinge 23 are integrally formed element to be single, and the single element that is integrally formed can form described provided with the film
Vibrating diaphragm 20.
As shown in Fig. 2 the hinge 23 in the embodiment can be (substantially rectangular in shape for two cantilever hinges 23a, 23b
Connection strap), two cantilever hinges 23a, 23b are located at a short brink of rectangle oscillating airfoil 22, accordingly, two cantilever hinges
The short side of oscillating airfoil 22 is connected by 23a, 23b with the short side of the inner ring (being similarly rectangle) of neighbouring framework 21.Wherein, oscillating airfoil
Except the position of hinge 23 forms gap between 22 outward flange and the inner ring of framework 21, and the film is bridged in gap 24.
In the present embodiment, the V-arrangement bulge-structure 25 can be formed for the surface self-deformation of oscillating airfoil 22, can also
To be connected to by modes such as welding on the surface of oscillating airfoil 22.As preferred, the V-arrangement bulge-structure 25 passes through the table of oscillating airfoil 22
Deformation of surface figure into.Specifically, the V-arrangement bulge-structure 25 can be the punching structure on the surface of oscillating airfoil 22.Such as Fig. 3 institutes
Show, the framework 21, the oscillating airfoil 22 and the hinge 23 are arranged on same plane 200, and the punching structure is configured to
The prominent projection in the plane 200.Specifically, the V-arrangement bulge-structure 25 is protruded along away from the direction of (or remote) back cavity 12.
In the present embodiment, oscillating airfoil 22 is provided with V-arrangement bulge-structure 25, and the V-arrangement bulge-structure 25, which can be lifted, to shake
The resonant frequency of the dynamic wing 22.Wherein, the V-arrangement bulge-structure 25 is by the resonance transfer of oscillating airfoil 22 a to preset frequency, and this makes a reservation for
Frequency is higher than 5KHz, in experiments it is found that, the preset frequency can substantially reduce triggering sympathetic response in 6KHz-8KHz scopes and produce
Probability.In an actual embodiment, when the coil 30 is applied in pumping signal, the oscillating airfoil 22 is in the armature 50
When driving lower mobile, the resonance of oscillating airfoil 22 is transferred to 6KHz by the V-arrangement bulge-structure 25 from 5KHz.
In the present embodiment, by setting V-arrangement bulge-structure 25 on oscillating airfoil 22 so as to improve being total to for oscillating airfoil 22
This effect of vibration frequency is proved by lot of experiments.Specific experiment is, by one using structure (existing structure) shown in Fig. 1
Vibrating diaphragm with carrying out resonance test using the vibrating diaphragm 20 of X-shaped bulge-structure 100 shown in Fig. 2, two receiver vibrating diaphragms remove oscillating airfoil 22
On bulge-structure it is different outside, other experimental conditions are consistent.
The resonant frequency result that the experiment is obtained is as shown in Fig. 6 to 7.Wherein, Fig. 6 is Oscillation Amplitude and frequency test curve
Figure, from fig. 6, it can be seen that the vibrating diaphragm of traditional structure has a resonance peak, and the vibrating diaphragm in present embodiment in 5KHz positions
20 form resonance peak in 6KHz positions.See Fig. 7 again, Fig. 7 is vibration force and frequency test curve map, equally can be with from Fig. 7
Find out, the vibrating diaphragm of traditional structure has a resonance peak in 5KHz positions, and the vibrating diaphragm 20 in present embodiment is then at 6KHz
Put and form resonance peak after even more big frequency.
Therefore the frequency resonated it can be seen from result of the test relative to the vibrating diaphragm of existing structure (is located substantially at
5KHz positions), resonance transfer to higher frequency (can be located substantially at using the V-arrangement bulge-structure 25 of present embodiment
6KHz positions).
In addition, oscillating airfoil 22 is generally configured with multiple resonance modes (or resonant frequency), found by lot of experiments, the V-arrangement
Bulge-structure 25 can shift at least one resonance to higher frequency, and not change remaining resonant frequency, so as to vibration
Other mode of the wing 22 do not produce influence.Specifically, one of multiple resonance (frequency) can be transferred to by V-arrangement bulge-structure 25
Higher frequency, does not change remaining resonant frequency.
It can be seen that, the oscillating airfoil 22 in present embodiment so as to work as to the coil 30 by provided with V-arrangement bulge-structure 25, applying
Plus pumping signal, when the oscillating airfoil 22 is moved under the armature 50 drive, compared to shaking for no V-arrangement bulge-structure 25
The dynamic wing 22, the V-arrangement bulge-structure 25 is by the resonance transfer of the oscillating airfoil 22 to higher frequency, therefore, the embodiment
