In one embodiment of the present application, the electric vibrating reed 3 is an ion conduction vibrating reed;
when the voltage applied to the ion conduction vibration plate is a first voltage, the ion conduction vibration plate drives the mass block 2 to move along a first direction;
when the voltage applied to the ion conduction vibration plate is a second voltage, the ion conduction vibration plate drives the mass block 2 to move along a second direction;
wherein the first voltage and the second voltage are opposite in polarity, and the first direction is opposite to the second direction. That is, the first direction and the second direction are opposite to each other, and voltages with opposite polarities are alternately applied to the ion conduction vibration plate, so that the ion conduction vibration plate drives the mass block 2 to alternately move along the first direction and the second direction, thereby generating a vibration sense.
As shown in fig. 10, the ion conduction vibration piece includes a first electrode layer 101, an ion exchange resin layer 102, and a second electrode layer 103 stacked in this order, and the ion exchange resin layer 102 has a polymer electrolyte therein. The ion conduction vibration plate can be made of ion-exchange polymer metal composite (IPMC). The IPMC material is a novel electrically-actuated functional material, and uses an ion-exchange resin layer (such as fluorocarbon polymer, etc.) as a substrate, and plates a noble metal (such as platinum, silver, etc.) on the surface of the substrate to form electrode layers, i.e., a first electrode layer 101 and a second electrode layer 103. The ion exchange resin layer 102 includes a polymer electrolyte containing cations and anions, and the positions and the numbers of the cations and the anions in fig. 10 are only schematic and do not represent actual situations. As shown in fig. 11 and 12, when a voltage is applied to the IPMC in the thickness direction, hydrated cations in the polymer electrolyte move to the cathode side, causing a difference in swelling of the anode and cathode surfaces of the IPMC, thereby generating deformation and bending toward the anode surface, so that the degree of bending of the IPMC can be controlled by controlling the energization voltage or current of the IPMC, so that the IPMC is displaced in the transverse direction.
The IPMC material is a novel driving material and has the advantages of light driving weight, large displacement, low driving voltage and the like. The advantage of adopting IPMC is obvious, for example, IPMC is a non-magnetic material and can not generate magnetic interference; the displacement and velocity generated by IPMC deformation decrease in proportion to the thickness of IPMC, and the force generated by IPMC deformation increases in proportion to the cube of the thickness of IPMC. Therefore, the thickness of the IPMC can be set according to actual conditions to achieve the desired displacement, velocity and force generated by IPMC deformation.
By applying voltage to the ion conduction vibration plate of the electric vibration plate 3, cations in the polymer electrolyte move to the cathode side, so that the difference of swelling of the front side and the back side of the ion conduction vibration plate of the electric vibration plate 3 is caused, the ion conduction vibration plate of the electric vibration plate 3 can be deformed due to the difference, the voltage direction applied to the ion conduction vibration plate of the electric vibration plate 3 is changed alternately, the deformation direction of the ion conduction vibration plate of the electric vibration plate 3 can be changed alternately, and therefore the mass block 2 is driven to move alternately, and vibration feeling is generated. The vibration amplitude may be 0.1 mm to 10 mm, and the vibration amplitude may be controlled by setting the thickness of the electric vibrating piece 3 ion conduction vibrating piece and adjusting the magnitude of the current passing through the electric vibrating piece 3 ion conduction vibrating piece.
Fig. 7 is a schematic view showing the distribution of cations in the electroluminescent vibrating reed 3 when a positive current is applied to the electroluminescent vibrating reed 3, wherein the cations move to the cathode side of the electroluminescent vibrating reed 3 (i.e. the second surface 32 of the electroluminescent vibrating reed 3 in fig. 7), the electroluminescent vibrating reed 3 moves upward and drives the mass 2 to move upward, and the direction of the arrow in fig. 7 is the moving direction of the electroluminescent vibrating reed 3.
Fig. 8 is a schematic diagram showing the distribution of cations in the electroluminescent vibrating reed 3 when a negative direction current is applied to the electroluminescent vibrating reed 3, wherein the cations move to the cathode side of the electroluminescent vibrating reed 3 (i.e. the first surface 31 of the electroluminescent vibrating reed 3 in fig. 8), the electroluminescent vibrating reed 3 moves downward and drives the mass 2 to move downward, and the direction of the arrow in fig. 8 is the moving direction of the electroluminescent vibrating reed 3. By applying a voltage to the ion conduction vibration plate, cations in the polymer electrolyte of the ion conduction vibration plate move to the cathode side, causing a difference in swelling of the front and back surfaces, so that the ion conduction vibration plate is deformed. When an alternating current is applied to the ion conduction vibration plate, the ion conduction vibration plate drives the mass block 2 to vibrate back and forth, thereby generating vibration.
Under the radiating scene of needs monitoring electronic equipment, monitor the temperature through the temperature sensor in the electronic equipment, reach the radiating temperature point of needs after, electronic equipment exports the low-power consumption signal of telecommunication about 0.05W to electroproduction trembler 3, the electroproduction trembler 3 alright reciprocating vibration of circular telegram to drive the peripheral vibration of quality piece 2 and the sound production, thereby remind user's electronic equipment that the temperature is higher, need the heat dissipation, in order to avoid equipment to damage.
Under the scene that needs automatic heat dissipation, monitor the temperature through the temperature sensor in the electronic equipment, reach the temperature point that needs the heat dissipation after, the electronic equipment exports the low-power consumption signal of telecommunication of about 0.05W to electroproduction trembler 3, and the electroproduction trembler 3 of circular telegram alright reciprocating vibration to drive the vibration of quality piece 2, thereby drive the air flow and dispel the heat.
Further, when the voltage applied to the ion conduction vibration plate is a first voltage, the ion conduction vibration plate drives the mass block 2 to move a first distance along a first direction;
when the voltage applied to the ion conduction vibration plate is a third voltage, the ion conduction vibration plate drives the mass block 2 to move a second distance along the first direction;
the first voltage and the third voltage have the same polarity, the third voltage is greater than the first voltage, and the first distance is different from the second distance.
The first voltage and the third voltage have the same polarity, the third voltage is greater than the first voltage, and the first distance is different from the second distance, for example, the second distance may be greater than the first distance. When the mass block 2 is required to move a larger distance, the mass block 2 can be driven to move a larger distance by applying a larger voltage to the ion conduction vibration plate; when the mass 2 is required to move a small distance, the mass 2 can be driven to move a small distance by applying a large voltage to the ion conduction vibration plate. There is a correspondence between the magnitude of the voltage applied to the ion conduction vibration plate and the moving distance of the mass 2, and the magnitude of the voltage applied to the ion conduction vibration plate can be determined based on the correspondence when the distance that the mass 2 needs to move is determined.
Further, when the voltage applied to the ion conduction vibration plate is a first voltage, the ion conduction vibration plate drives the mass 2 to move in the first direction at a first rate;
when the voltage applied to the ion conduction vibration plate is a third voltage, the ion conduction vibration plate drives the mass block 2 to move along the first direction at a second speed;
the first voltage and the third voltage have the same polarity, the third voltage is greater than the first voltage, and the first rate is different from the second rate. For example, the second rate may be less than the first rate. When the mass block 2 is required to move at a high speed, the mass block 2 can be driven to move at a high speed by applying high voltage to the ion conduction vibration plate; when the moving speed of the mass block 2 is required to be small, the mass block 2 can be driven to move at a small speed by applying a small voltage to the ion conduction vibration plate. There is a correspondence between the magnitude of the voltage applied to the ion conduction vibration plate and the moving speed of the mass 2, and the magnitude of the voltage applied to the ion conduction vibration plate can be determined based on the correspondence in the case of determining the speed at which the mass 2 needs to move.
