Referring to fig. 4, fig. 4 is a schematic structural diagram of a piezoelectric ceramic single body in the electronic device shown in fig. 1. The shape of the single piezoelectric ceramic body 400 may be a regular shape, for example, the single piezoelectric ceramic body 400 may have a rectangular structure, a rounded rectangular structure, a circular structure, or the like. The piezoelectric ceramic single body 400 may also have an irregular shape.
The piezoelectric ceramic unit 400 may include a first piezoelectric ceramic sheet 410, a diaphragm 420, and a second piezoelectric ceramic sheet 430, which are stacked. The first piezoceramic sheet 410 and the second piezoceramic sheet 430 are conductors and may be used to conduct current. Diaphragm 420 is a non-conductor and may not be used to conduct current.
The size of the diaphragm 420 is larger than the size of the first piezoceramic sheet 410 and the second piezoceramic sheet 430. The diaphragm 420 may include a first region and a second region, the second region being disposed at a periphery of the first region. For example, the second region may be disposed around the periphery of the first region. Wherein the first piezoceramic sheet 410 and the second piezoceramic sheet 430 are arranged in the first zone such that the second zone is exposed.
The first piezoceramic sheet 410 and the second piezoceramic sheet 430 are respectively electrically connected to an ac power source, such as the ac power source 600, for converting the electrical energy output by the ac power source 600 into mechanical energy. The ac power supply 600 is used to output an ac voltage, and the ac power supply 600 may include a first electrode 610 and a second electrode 620 having different potential values.
The first piezoceramic wafer 410 has a first end face and a second end face opposite to the first end face, wherein the first end face is a face away from the diaphragm 420, and the second end face is a face connected to the first region. The first end surface is electrically connected to the first electrode 610 of the ac power source 600, and the second end surface is electrically connected to the second electrode 620 of the ac power source 600.
The second piezoceramic sheet 430 has a third end face and a fourth end face opposite to the third end face, wherein the third end face is connected to the first region, and the fourth end face is away from the diaphragm 420. The third end surface is electrically connected to the second electrode 620 of the ac power source 600, and the fourth end surface is electrically connected to the first electrode 620 of the ac power source 600.
As shown in fig. 5 and 6, fig. 5 is a schematic structural view of the piezoelectric ceramic single body shown in fig. 4 in a first bending state, and fig. 6 is a schematic structural view of the piezoelectric ceramic single body shown in fig. 4 in a second bending state.
The alternating voltage direction of the ac power supply 600 may change with time along with the direction, the piezoelectric ceramic unit 400 may perform a deformation motion along with the alternating voltage direction, and the deformation motion of the piezoelectric ceramic unit 400 may cause ambient air to flow, thereby generating a sound.
For example, as shown in fig. 5, when the alternating voltage direction of the ac power supply 600 is output from the first electrode 610 and returns to the second electrode 620, at this time, under the action of the electric field, the first piezoelectric ceramic piece 410 and the second piezoelectric ceramic piece 430 polarize the respective polarization vectors of the original disorientation preferentially along the electric field direction, because the direction of the external electric field of the first piezoelectric ceramic piece 410 is opposite to the direction of the external electric field of the second piezoelectric ceramic piece 430, the polarization direction of the first piezoelectric ceramic piece 410 is opposite to the polarization direction of the second piezoelectric ceramic piece 430, the polarization direction of the first piezoelectric ceramic piece 410 is the same as the voltage direction of the ac power supply 600, and the first piezoelectric ceramic piece 410 is elongated to bend toward the diaphragm 420; the polarization direction of the second piezoceramic sheet 430 is opposite to the voltage direction of the ac power supply 600, and the second piezoceramic sheet 430 is shortened, so that the second piezoceramic sheet 410 bends in the direction away from the diaphragm 420, and the diaphragm 420 also deforms under the action of the first piezoceramic sheet 410 and the second piezoceramic sheet, so that the piezoceramic monomer 400 assumes the first bending state.
As shown in fig. 6, when the alternating voltage direction of the ac power source 600 is output from the second electrode 620 and returns to the first electrode 610, the polarization direction of the first piezoelectric ceramic piece 410 is opposite to the voltage direction of the ac power source 600, the first piezoelectric ceramic piece 410 is shortened, the first piezoelectric ceramic piece 410 is bent in a direction away from the diaphragm 420, the second piezoelectric ceramic piece 430 is extended, the second piezoelectric ceramic piece 410 is bent in a direction toward the diaphragm 420, and the diaphragm 420 is also deformed under the action of the first piezoelectric ceramic piece 410 and the second piezoelectric ceramic piece, so that the piezoelectric ceramic unit 400 assumes a second bending state.
The electronic device 20 can control the piezoelectric ceramic single body 400 to perform the deformation motion by controlling the alternating voltage of the alternating current power supply 600 to switch the piezoelectric ceramic single body 600 between the first bending state and the second bending state.
Wherein the deformation amplitude of the piezoelectric ceramic single body 400 can be related to the voltage amplitude of the alternating voltage. For example, the deformation amplitude of the piezoelectric ceramic unit 400 may be proportional to the voltage amplitude of the alternating voltage. When the electronic device 20 controls the voltage amplitude of the alternating voltage of the alternating power supply 600 to increase, the deformation amplitude of the piezoelectric ceramic single body 400 increases accordingly, and stronger air fluctuation can be driven to form larger volume, so that the loudness of the audio signal is increased. Of course, the deformation amplitude of the piezoelectric ceramic single body 400 may be inversely proportional to the voltage amplitude of the alternating voltage, and in this case, the electronic device 20 may increase the deformation amplitude of the piezoelectric ceramic single body 400 by decreasing the voltage amplitude of the alternating voltage.
In the embodiment of the application, the first piezoelectric ceramic piece 410 and the second piezoelectric ceramic piece 430 are arranged in the first area, so that the second area of the diaphragm 420 is exposed outside, the first area is deformed by the acting force exerted by the first piezoelectric ceramic piece 410 and the second piezoelectric ceramic piece 430, and the second area keeps the original state without the action of external force, so that the deformation amplitude of the diaphragm 420 can be increased compared with the second area without the exposure.
It should be noted that the piezoelectric ceramic unit 400 may also include only the first piezoelectric ceramic piece 410 and the diaphragm 420, and the first piezoelectric ceramic piece 410 may drive the diaphragm 420 to deform. Of course, the single piezoelectric ceramic 400 may also include a plurality of first piezoelectric ceramic pieces 410 and/or a plurality of second piezoelectric ceramic pieces 430, and the number of the first piezoelectric ceramic pieces 410 and the number of the second piezoelectric ceramic pieces 430 may be set according to practical situations, which is not limited in this embodiment of the application.
The piezoelectric ceramic unit 400 may be fixed by an adhesive method. For example, glue may be coated on a first end surface of the first piezoceramic sheet 410, and the first end surface of the first piezoceramic sheet 410 is attached to the inner surface of the second side 120.
