Moreover, the second region 120 is disposed on the ceramic rear cover 100, the second region 120 generates vibration and directly emits a sound signal to the outside of the electronic device 10, and a transmission hole for the sound signal does not need to be formed on the electronic device 10, so that an opening on the electronic device 10 can be reduced, and the dustproof and waterproof performance of the electronic device and the electronic device can be improved; meanwhile, the electronic device 10 does not need to additionally provide a sound guide channel of the sound signal, and the structure of the electronic device 10 can be simplified.
The structure of one of the second regions 120 is described in detail below. Referring to fig. 3, fig. 3 is a schematic structural view of a second region of the ceramic rear cover shown in fig. 1.
The second region 120 may include a first piezoceramic sheet 121, a diaphragm 122 and a second piezoceramic sheet 123 arranged in a stack. The first piezoceramic sheet 121 and the second piezoceramic sheet 123 are conductors and can be used for conducting current. The diaphragm 122 is non-conductive and may not be used to conduct current.
The size of the diaphragm 122 is larger than the sizes of the first and second piezoceramic sheets 121 and 123. The diaphragm 122 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. The first piezoelectric ceramic plate 121 and the second piezoelectric ceramic plate 123 are disposed in the first region, so that the second region is exposed.
The first piezoelectric ceramic piece 121 and the second piezoelectric ceramic piece 123 are respectively electrically connected to an ac power source, such as an ac power source 310, for converting the electric energy output by the ac power source 310 into mechanical energy. The ac power supply 310 is used to output an ac voltage, and the ac power supply 310 may include a first electrode 311 and a second electrode 312 having different potential values.
The first piezoceramic sheet 121 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 122, and the second end face is a face connected to the first region. The first end surface is electrically connected to the first electrode 311 of the ac power source 310, and the second end surface is electrically connected to the second electrode 312 of the ac power source 310.
The second piezoceramic sheet 123 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 122. The third end surface is electrically connected to the second electrode 312 of the ac power source 310, and the fourth end surface is electrically connected to the first electrode 311 of the ac power source 310.
In the description of the present application, it is to be understood that terms such as "first," "second," "third," and the like are used solely for distinguishing between similar elements and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.
As shown in fig. 4 and 5, fig. 4 is a schematic structural view of the second region shown in fig. 3 in a first bending state, and fig. 5 is a schematic structural view of the second region shown in fig. 3 in a second bending state.
The alternating voltage direction of the ac power source 310 may change with time, the ceramic rear cover 100 may perform a deformation motion with the alternating voltage direction, and the deformation motion of the ceramic rear cover 100 may cause ambient air to flow, thereby generating sound.
For example, as shown in fig. 4, when the alternating voltage direction of the ac power supply 310 is output from the first electrode 311 and returns to the second electrode 312, at this time, under the action of the electric field, the first piezoelectric ceramic piece 121 and the second piezoelectric ceramic piece 123 make the respective polarization vectors of the original disorientation preferentially orient to the sounding polarization along the electric field direction, because the direction of the external electric field of the first piezoelectric ceramic piece 121 is opposite to the direction of the external electric field of the second piezoelectric ceramic piece 123, the polarization direction of the first piezoelectric ceramic piece 121 is opposite to the polarization direction of the second piezoelectric ceramic piece 123, the polarization direction of the first piezoelectric ceramic piece 121 is the same as the voltage direction of the ac power supply 310, and the first piezoelectric ceramic piece 121 is elongated, so that the first piezoelectric ceramic piece 121 is bent toward the diaphragm 122; the polarization direction of the second piezoelectric ceramic piece 123 is opposite to the voltage direction of the ac power supply 310, the second piezoelectric ceramic piece 123 is shortened, the second piezoelectric ceramic piece 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 piece 121 and the second piezoelectric ceramic piece 123, so that the ceramic rear cover 100 exhibits the first bending state.
As shown in fig. 5, when the alternating voltage direction of the ac 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 piece 121 is opposite to the voltage direction of the ac power source 310, the first piezoelectric ceramic piece 121 is shortened, the first piezoelectric ceramic piece 121 is bent in a direction away from the diaphragm 122, the second piezoelectric ceramic piece 123 is extended, the second piezoelectric ceramic piece 123 is bent in a direction toward the diaphragm 122, and the diaphragm 122 is also deformed by the first piezoelectric ceramic piece 121 and the second piezoelectric ceramic piece 123, so that the ceramic back cover 100 assumes a second bent state.
The electronic device 10 can control the ceramic back cover 100 to perform the deformation motion by controlling the alternating voltage of the alternating current power source 310 to switch the ceramic back cover 100 between the first bending state and the second bending state.
It should be noted that the deformation amplitudes of the first piezoceramic sheet 121 and the second piezoceramic sheet 122 in fig. 4 and 5 are only examples, and in practical applications, the deformation amplitudes of the first piezoceramic sheet 121 and the second piezoceramic sheet 123 may be controlled in a range that is not easily perceived by human eyes by controlling an alternating voltage, or the like, so as to maintain the electronic device 10 to have a stable external shape structure.
Wherein the deformation amplitude of the second region 120 may be associated with the voltage amplitude of the alternating voltage. For example, the magnitude of the deformation of the second region 120 may be proportional to the voltage magnitude of the alternating voltage. When the electronic device 10 controls the voltage amplitude of the alternating voltage of the alternating power supply 123 to increase, the deformation amplitude of the second region 120 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, it is also possible that the deformation magnitude of the second region 120 is inversely proportional to the voltage magnitude of the alternating voltage, in which case the electronic device 10 may increase the deformation magnitude of the second region 120 by decreasing the voltage magnitude of the alternating voltage.
In the embodiment of the application, the first piezoelectric ceramic piece 121 and the second piezoelectric ceramic piece 123 are arranged in the first area, so that the second area of the diaphragm 122 is exposed outside, the first area is deformed by the acting force exerted by the first piezoelectric ceramic piece 121 and the second piezoelectric ceramic piece 123, and the second area keeps the original state without the action of external force, so that the deformation amplitude of the diaphragm 122 can be increased compared with the second area without the exposure.
It should be noted that the second region 120 may also include only the first piezoceramic sheet 121 and the diaphragm 122, and the first piezoceramic sheet 121 may drive the diaphragm 122 to deform. Of course, the second region 120 may also include a plurality of first piezoceramic wafers 121 and/or a plurality of second piezoceramic wafers 123, and the number of the first piezoceramic wafers 121 and the number of the second piezoceramic wafers 123 may be set according to practical situations, which is not limited in the embodiment of the present application.
Here, the structure of the first region 110 may be the same as that of the second region 120 in the embodiment of the present application. That is, the structure of the first region 110 may also include a first piezoelectric ceramic plate, a diaphragm, and a second piezoelectric ceramic plate, which are stacked, and the first piezoelectric ceramic plate and the second piezoelectric ceramic plate are conductors and may be used for conducting current. The diaphragm is non-conductive and cannot be used to conduct current. The specific structure of the first region 110 can refer to the specific structure of the second region 120, and is not described herein again.
It is understood that the second area 120 is used for converting the electrical signal into the sound signal to realize the transmission of the sound signal, and the first area 110 is used for converting the fingerprint information, the pressure signal, the sound signal and other triggering instructions into the electrical signal to realize the reception of the triggering instructions. Thus, the amplitude of the second region 120 and the amplitude of the first region 110 may be different to achieve different functions of the second region 120 and the first region 110.
In the electronic device 10 according to the embodiment of the present application, the second area 120 may implement a function of a speaker to implement the sound signal.

It is to be understood that the second channel sound signal and the first channel sound signal may be sound signals of different channels. The second driving circuit 300 may include a second audio selection circuit 340 and a second power amplification circuit 350. The processor 400, the second audio signal selection circuit 340, the second power amplification circuit 350, and the second sub-region 125 may form a second signal path to implement transmission of a second channel sound signal.

Specifically, the ceramic back cover 100 includes a first end and a second end disposed oppositely, the first sub-region 124 may be located at the first end, and the second sub-region 125 may be located at the second end. Furthermore, the first sub-area 124 and the second sub-area 125 are far apart from each other, and when the first sub-area and the second sub-area transmit the sound signals together, the stereo sound signal mixing effect obtained by mixing the first channel sound signal and the second channel sound signal is better.

Wherein the triggering instructions of the first sound emission pattern, the second sound emission pattern and the third sound emission pattern can be detected by different sub-areas on the first area 110.
Specifically, please refer to fig. 8, where fig. 8 is a third structural schematic diagram of a ceramic rear cover of an electronic device according to an embodiment of the present disclosure. The first region 110 may include a third sub-region 111, a fourth sub-region 112, and a fifth sub-region 113.
The third sub-area 111 may be configured to detect a first trigger instruction of the first sound emitting mode, and transmit the first trigger instruction to the first driving circuit 200 and transmit the first trigger instruction to the processor 400, and the processor 400 may control the second driving circuit 300 and the second driving circuit 300 to drive the first sub-area 124 to transmit the first channel sound signal according to the first trigger instruction.

For example, the first trigger instruction is a sound signal trigger instruction, the second trigger instruction is a pressure trigger instruction, and the third trigger instruction is an ultrasonic detection trigger instruction.
Of course, the category of at least one of the first trigger instruction, the second trigger instruction, and the third trigger instruction may also be the same. For example, the first trigger instruction, the second trigger instruction, and the third trigger instruction are pressure trigger instructions, when the third sub-area 111 detects a pressure trigger instruction, the processor 400 controls the electronic device 10 to switch to the first sound emission mode, when the fourth sub-area 112 detects a pressure trigger instruction, the processor 400 controls the electronic device 10 to switch to the second sound emission mode, and when the fifth sub-area 113 detects a pressure trigger instruction, the processor 400 controls the electronic device 10 to switch to the third sound emission mode.

The triggering instructions of the first sound emission pattern, the second sound emission pattern and the third sound emission pattern may also be detected by the same sub-area on the first area 110.
Specifically, when the first driving circuit 200 drives the first area 110 to detect a first trigger instruction, the electronic device 10 switches to the first sound emitting mode under the action of the first trigger instruction; when the first driving circuit 200 drives the first area 110 to detect the second trigger instruction, the electronic device 10 is switched to the second sound emitting mode under the action of the second trigger instruction; when the first driving circuit 200 drives the first area 110 to detect the second trigger instruction, the electronic device 10 is switched to the third sound emitting mode under the action of the third trigger instruction.
When the first trigger instruction, the second trigger instruction and the third trigger instruction are received from the first area 110, the first trigger instruction, the second trigger instruction and the third trigger instruction are different trigger instructions, so that the processor 400 switches to different sound emission modes according to different trigger instructions.

It is understood that the second driving circuit 300 may make the first driving power larger than the second driving power by changing the form of the voltage. The second driving circuit 300 may also make the first driving power larger than the second driving power by changing the form of the amplification power of the power amplifier.
For example, the second driving circuit 300 may include a first path and a second path, and in the fourth sound generating mode, the first path may include a third power amplifier, and the third power amplifier may amplify the electrical signal transmitted by the first path with a larger first amplification power, so that under the action of the amplified electrical signal, the second region 120 vibrates to generate a first sound signal with a larger volume, and a speaker function may be implemented.
Under the fifth sound production mode, the second path may include a fourth power amplifier, and the fourth power amplifier amplifies the electrical signal transmitted through the second path with the second amplification power, so that under the effect of the amplified electrical signal, the second region 120 vibrates to generate a second sound signal with low volume, thereby implementing the function of an earphone and ensuring the privacy of sound signal transmission.
In the electronic device 10 of the embodiment of the application, the second driving circuit 300 is utilized to switch the second region 120 between the speaker mode and the earphone mode, so that the number of sound generating devices can be reduced, and the second region 120 is disposed on the ceramic rear cover 100, so that a sound transmission channel is not required to be disposed, and the structure of the electronic device 10 is simplified.
