A structure of the second region 120 will be described in detail below. Please refer to FIG. 3 , which is a schematic structural diagram of the second region of the ceramic back cover shown in FIG. 1 .

The second region 120 may include a first piezoelectric ceramic sheet 121 , a diaphragm 122 and a second piezoelectric ceramic sheet 123 that are stacked in layers. The first piezoelectric ceramic sheet 121 and the second piezoelectric ceramic sheet 123 are conductors, which can be used to conduct current. Diaphragm 122 is a non-conductor and cannot be used to conduct current.

In the description of this application, it should be understood that terms such as "first", "second", "third" etc. are only used to distinguish similar objects, and should not be construed as indicating or implying relative importance or implying Indicates the number of technical features indicated.

As shown in FIGS. 4 and 5 , FIG. 4 is a schematic structural diagram of the second region shown in FIG. 3 in a first curved state, and FIG. 5 is a structural schematic diagram of the second region shown in FIG. 3 in a second curved state.

The direction of the alternating voltage of the AC power source 310 can change with time along with the direction. The air moves, which makes the sound.

For example, as shown in FIG. 4 , when the alternating voltage direction of the AC power source 310 is output from the first electrode 311 and returns to the second electrode 312 , the first piezoelectric ceramic sheet 121 and the second piezoelectric ceramic sheet 123 are Under the action of the electric field, the original chaotically oriented respective polarization vectors are preferentially oriented along the direction of the electric field to emit sound polarization, because the applied electric field direction of the first piezoelectric ceramic sheet 121 is opposite to the applied electric field direction of the second piezoelectric ceramic sheet 123 , the polarization direction of the first piezoelectric ceramic sheet 121 is opposite to the polarization direction of the second piezoelectric ceramic sheet 123, and the polarization direction of the first piezoelectric ceramic sheet 121 is the same as the voltage direction of the AC power source 310. The electric ceramic sheet 121 is elongated, so that the first piezoelectric ceramic sheet 121 is bent toward the direction of the diaphragm 122; the polarization direction of the second piezoelectric ceramic sheet 123 is opposite to the voltage direction of the AC power source 310, and the second piezoelectric ceramic sheet 123 shortened, so that the second piezoelectric ceramic sheet 123 is bent in a direction away from the diaphragm 122, and the diaphragm 122 is also deformed under the action of the first piezoelectric ceramic sheet 121 and the second piezoelectric ceramic sheet 123, so that the ceramic back cover 100 The first bending state is exhibited.

As shown in FIG. 5 , when the alternating voltage direction of the alternating current power source 310 is output from the second electrode 312 and returns to the first electrode 311 , the polarization direction of the first piezoelectric ceramic sheet 121 is opposite to the voltage direction of the alternating current power source 310 , the first piezoelectric ceramic sheet 121 is shortened, so that the first piezoelectric ceramic sheet 121 is bent in a direction away from the diaphragm 122 , and the second piezoelectric ceramic sheet 123 is elongated, so that the second piezoelectric ceramic sheet 123 faces the direction of the diaphragm 122 When the direction is bent, the diaphragm 122 is also deformed under the action of the first piezoelectric ceramic sheet 121 and the second piezoelectric ceramic sheet 123, so that the ceramic back cover 100 exhibits a second bending state.

The electronic device 10 can switch the ceramic back cover 100 between the first bending state and the second bending state by controlling the alternating voltage of the AC power source 310 to control the ceramic back cover 100 to perform deformation movement.

Wherein, the deformation amplitude of the second region 120 may be associated with the voltage amplitude of the alternating voltage. For example, the deformation amplitude of the second region 120 may be proportional to the voltage amplitude of the alternating voltage. When the voltage amplitude of the alternating voltage of the AC power source 123 controlled by the electronic device 10 increases, the deformation amplitude of the second area 120 increases accordingly, which can drive stronger air fluctuations to form a larger volume, thereby increasing the audio signal the loudness. Of course, the deformation amplitude of the second region 120 may also be inversely proportional to the voltage amplitude of the alternating voltage. In this case, the electronic device 10 can increase the deformation amplitude of the second region 120 by reducing the voltage amplitude of the alternating voltage. .

In this embodiment of the present application, by arranging the first piezoelectric ceramic sheet 121 and the second piezoelectric ceramic sheet 123 in the first area, the second area of the diaphragm 122 is exposed, so that the first piezoelectric ceramic sheet 121 is exposed to the first area. The deformation occurs with the force exerted by the second piezoelectric ceramic sheet 123 , and the second region maintains the original state without external force, which can increase the deformation amplitude of the diaphragm 122 compared to the second region without exposure.

It should be noted that the second region 120 may also only include the first piezoelectric ceramic sheet 121 and the diaphragm 122, and the first piezoelectric ceramic sheet 121 can drive the diaphragm 122 to deform. Of course, the second region 120 may also include a plurality of first piezoelectric ceramic sheets 121 and/or a plurality of second piezoelectric ceramic sheets 123, and the number of the first piezoelectric ceramic sheets 121 and the second piezoelectric ceramic sheets 123 may be determined according to It is set according to the actual situation, which is not limited in this embodiment of the present application.
