Such as: plastic cement, but not limited to this, is used with carrying out insulation.The conductive sheet 125 of the present embodiment is by conductive material institute structure
At, such as: metal, but not limited to this, and conduct being used, and the conductive sheet 125 of the present embodiment further includes conduction and connects
Foot 1251, conduct being used, but not limited to this.
Please refer to Fig. 3 A, Fig. 3 B and Fig. 5 A to Fig. 5 E, wherein Fig. 5 A to Fig. 5 E is the work of actuator shown in Fig. 3 A
Dynamic schematic diagram.Firstly, as shown in Figure 5A, actuator 12 is sequentially by the first protecting film 141, inlet plate 121, resonance plate 122, pressure
Electric actuator 123, insulating trip 1241, conductive sheet 125 and another insulating trip 1242 etc. stack, wherein resonance plate 122 and pressure
It is with gap g0, between the resonance plate 122 of the present embodiment and the outline border 1231 of piezoelectric actuator 123 between electric actuator 123
Gap g0 in fill conducting resinl, but not limited to this, so that the suspension board 1230 of resonance plate 122 and piezoelectric actuator 123
The depth of gap g0 can be maintained between the 1230c of protrusion, and then can be guided air-flow and more quickly be flowed, and because of suspension board 1230
Protrusion 1230c and resonance plate 122 keep suitable distance to make the interference reduction that is in contact with each other, and promote noise generation that can be lowered；In another
It, also can be by the height for the outline border 1231 for increasing piezoelectric actuator 123, so that it is assembled with resonance plate 122 in some embodiments
Mono- gap Shi Zengjia, but not limited to this.
It please continue refering to Fig. 5 A to Fig. 5 E, as shown, when the first protecting film 141, inlet plate 121, resonance plate 122 and piezoelectricity
Actuator 123 is sequentially after corresponding assembling, and the first protecting film 141 closes the air inlet 1210 of inlet plate 121, in resonance plate 122
Common definition forms the chamber of a confluence gas, and resonance plate 122 between hollow bore 120 and the central recess of inlet plate 121 1211
Common definition forms first chamber 121 between piezoelectric actuator 123, is configured to temporarily store gas, and first chamber 121 is through altogether
Shake piece 122 hollow bore 120 and be connected with the chamber at the central recess 1211 of 121 lower surface of inlet plate, and the first chamber
The two sides of room 121 then by the gap 1235 between the bracket 1232 of piezoelectric actuator 123 and with 110 (such as Fig. 2 of the chamber of outer cover 11
It is shown) it is connected.
In this present embodiment, when 12 actuation of actuator, mainly by piezoelectric actuator 123 by voltage actuation and with bracket
1232 be fulcrum, carries out the reciprocating vibration of vertical direction.As shown in Figure 5 B, when piezoelectric actuator 123 by voltage actuation and to
When lower vibration, then gas is after the first protecting film 141 filters aqueous vapor and dust, by at least air inlet on inlet plate 121
1210 enter, and through at least one confluence round 1212 of its lower surface to be pooled at the central recess 1211 in center, then pass through
It is flowed downwardly by the central hole 120 being correspondingly arranged on resonance plate 122 with central recess 1211 into first chamber 121, thereafter,
Due to the drive vibrated by piezoelectric actuator 123, resonance plate 122 also can with resonance and carry out vertical reciprocating vibration, such as
Shown in Fig. 5 C, then for resonance plate 122 also with downward vibration, and attach the suspension board 1230 for contacting at piezoelectric actuator 123
On the 1230c of protrusion, by the deformation of this resonance plate 122, to compress the volume of first chamber 121, and close in first chamber 121
Between free air space, promote the gas in it push to two sides flow, and then by piezoelectric actuator 123 bracket 1232 between
Gap 1235 and pass through flowing downwards.As for Fig. 5 D then it is that its resonance plate 122 returns back to initial position, and piezoelectric actuator 123
It is driven by voltage to vibrate upwards, the so same volume for squeezing first chamber 121, only at this time since piezoelectric actuator 123 is
The displacement of lifting upwards, the lifting can be d, so that the gas in first chamber 121 can be flowed towards two sides, and then band is taken offence
Body is constantly filtered via the first protecting film 141, and is entered from the air inlet 1210 on inlet plate 121, then flow into central recess
1211 are formed by chamber, then as shown in fig. 5e, and resonance plate 122 is resonated by the vibration that piezoelectric actuator 123 is lifted upwards
Upwards, and then flow into the gas in central recess 1211 in first chamber 121 by the central hole 120 of resonance plate 122 again,
And pass through outflow actuator 12 downwards via the gap 1235 between the bracket of piezoelectric actuator 123 1232.In this way,
Barometric gradient is generated in runner design through this actuator 12, makes gas flow at high rates, and through the impedance in runner disengaging direction
Gas is transmitted to outlet side by suction side by difference, and in the state that outlet side has air pressure, still has the ability persistently to release gas
Body, and can reach mute effect.In some embodiments, the vertical reciprocating type vibration frequency of resonance plate 122 is can be with piezoelectricity
The vibration frequency of actuator 123 is identical, i.e., it is that can appoint according to actually situation is applied that the two can be simultaneously upwards or downward simultaneously
Variation is applied, not to be limited shown in the present embodiment as flowing mode.
