Referring to fig. 2, fig. 2 is a schematic structural diagram of a piezoelectric ceramic single body in the electronic device shown in fig. 1. The shape of the piezoelectric ceramic single body 200 may be a regular shape, for example, the piezoelectric ceramic single body 200 may have a rectangular structure, a rounded rectangular structure, a circular structure, or the like. The piezoelectric ceramic monolith 200 may have an irregular shape.
The single piezoelectric ceramic body 200 may include a first piezoelectric ceramic sheet 210, a diaphragm 220, and a second piezoelectric ceramic sheet 230, which are stacked. The first piezoceramic sheet 210 and the second piezoceramic sheet 230 are conductors and may be used to conduct current. Diaphragm 220 is a non-conductor and may not be used to conduct current.
the size of the diaphragm 220 is larger than the size of the first piezoceramic sheet 210 and the second piezoceramic sheet 230. The diaphragm 220 may include a first region 221 and a second region 222, the second region 222 being disposed at a periphery of the first region 221. For example, the second region 222 may be disposed around the periphery of the first region 221. Wherein the first piezoceramic sheet 210 and the second piezoceramic sheet 230 are arranged in the first zone 221 such that the second zone 222 is exposed.
The first piezoelectric ceramic plate 210 and the second piezoelectric ceramic plate are respectively electrically connected to an ac power source such as the ac power source 400, so as to convert the electric energy output by the ac power source 400 into mechanical energy.

the alternating voltage direction of the alternating current power supply 400 may change with time along with the direction, the piezoelectric ceramic single body 200 may perform a deformation motion along with the alternating voltage direction, and the deformation motion of the piezoelectric ceramic single body 200 may cause ambient air to flow, thereby emitting sound.
For example, as shown in fig. 3, when the alternating voltage direction of the ac power supply 400 is output from the first electrode 410 and returns to the second electrode 420, at this time, under the action of the electric field, the first piezoelectric ceramic piece 210 and the second piezoelectric ceramic piece 230 polarize the respective polarization vectors of the original disorientation along the preferred orientation of the electric field direction, because the direction of the external electric field of the first piezoelectric ceramic piece 210 is opposite to the direction of the external electric field of the second piezoelectric ceramic piece 230, the polarization direction of the first piezoelectric ceramic piece 210 is opposite to the polarization direction of the second piezoelectric ceramic piece 230, the polarization direction of the first piezoelectric ceramic piece 210 is the same as the voltage direction of the ac power supply 400, and the first piezoelectric ceramic piece 210 is elongated, so that the first piezoelectric ceramic piece 210 is bent toward the diaphragm 220; the polarization direction of the second piezoceramic sheet 230 is opposite to the voltage direction of the ac power supply 400, and the second piezoceramic sheet 230 is shortened, so that the second piezoceramic sheet 210 bends in the direction away from the diaphragm 220, and the diaphragm 220 also deforms under the action of the first piezoceramic sheet 210 and the second piezoceramic sheet, so that the piezoceramic monomer 200 assumes the first bending state.
As shown in fig. 4, when the alternating voltage direction of the ac power source 400 is output from the second electrode 420 and returns to the first electrode 410, the polarization direction of the first piezoceramic sheet 210 is opposite to the voltage direction of the ac power source 400, the first piezoceramic sheet 210 is shortened, the first piezoceramic sheet 210 is bent in the direction away from the diaphragm 220, the second piezoceramic sheet 230 is extended, the second piezoceramic sheet 210 is bent in the direction toward the diaphragm 220, and the diaphragm 220 is also deformed under the action of the first piezoceramic sheet 210 and the second piezoceramic sheet, so that the piezoceramic unit 200 assumes the second bending state.
the electronic device 20 can control the piezoelectric ceramic single body 200 to perform a deformation motion by controlling the alternating voltage of the alternating current power source 400 to switch the piezoelectric ceramic single body 200 between the first bending state and the second bending state.
wherein, the deformation amplitude of the piezoelectric ceramic single body 200 can be related to the voltage amplitude of the alternating voltage. For example, the deformation amplitude of the piezoelectric ceramic unit 200 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 400 to increase, the deformation amplitude of the piezoelectric ceramic single body 200 increases accordingly, and stronger air fluctuation can be driven to form larger volume, so that the loudness of the sound signal is increased. Of course, the deformation amplitude of the piezoelectric ceramic single body 200 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 200 by decreasing the voltage amplitude of the alternating voltage.
In the embodiment of the application, the first piezoelectric ceramic piece 210 and the second piezoelectric ceramic piece 230 are arranged in the first area 221, so that the second area 222 of the diaphragm 220 is exposed outside, the first area 221 is deformed by the acting force applied by the first piezoelectric ceramic piece 210 and the second piezoelectric ceramic piece 230, and the second area 222 keeps the original state without the action of external force, so that the deformation amplitude of the diaphragm 220 can be increased compared with the second area without the exposure.
It should be noted that the piezoelectric ceramic unit 200 may also include only the first piezoelectric ceramic piece 210 and the diaphragm 220, and the first piezoelectric ceramic piece 210 may drive the diaphragm 210 to deform. Of course, the piezoelectric ceramic unit 200 may also include a plurality of first piezoelectric ceramic pieces 210 and/or a plurality of second piezoelectric ceramic pieces 230, and the number of the first piezoelectric ceramic pieces 210 and the number of the second piezoelectric ceramic pieces 220 may be set according to practical situations, which is not limited in this embodiment of the application.
