The game mode is a game operation in which the user holds two short frames 101 of the electronic device 100 with both hands and frequently slides and clicks, and the video mode is a video playing mode in which the user holds the short frames 101 of the electronic device 100 with one hand.
When the electronic device 100 is in the landscape mode, the processor controls the first piezoelectric ceramic monomer 301 on the at least one long frame 102 to transmit a sound signal; when the electronic device 100 is in the portrait screen mode, the processor controls the first piezoelectric ceramic unit 301 on the at least one short frame 101 to transmit the sound signal, so that the situation that the user blocks the first piezoelectric ceramic unit 301 on the frame to influence the transmission of the sound signal by the first piezoelectric ceramic unit 301 due to the gesture of holding the electronic device 100 can be avoided.
When the electronic device 100 is in the landscape mode and the game mode, the processor controls the first piezoelectric ceramic units 301 disposed on at least one of the long frames 102 to transmit sound signals, and controls the first piezoelectric ceramic units 301 disposed on two of the short frames 101 not to transmit sound signals. Not only can avoid influencing the transmission of the sound signal by the first piezoelectric ceramic single body 301 due to the fact that the user shades the first piezoelectric ceramic single body 301 on the frame when holding the electronic device 100, but also only controls the first piezoelectric ceramic single body 301 arranged on at least one long frame 102 to transmit the sound signal and controls the first piezoelectric ceramic single bodies 301 arranged on two short frames 101 not to transmit the sound signal, thereby playing a role in saving the power consumption of the electronic device 100.

Not only can the influence on the transmission of the sound signal by the first piezoelectric ceramic single body 301 due to the fact that the first piezoelectric ceramic single body 301 on the frame is shielded by the posture of the user holding the electronic device 100 be avoided, but also the power consumption of the electronic device 100 can be saved.
Referring to fig. 7, fig. 7 is a schematic view illustrating a first structure of the piezoelectric ceramic unit 301 in fig. 4, where the piezoelectric ceramic unit 301 may have a regular shape, for example, the first piezoelectric ceramic unit 301 may have a rectangular structure, a rounded rectangular structure, a circular structure, and the like. The first piezoelectric ceramic single body 301 may have an irregular shape.
The first piezoelectric ceramic unit 301 may include a first piezoelectric ceramic sheet 3011, a membrane 3012, and a second piezoelectric ceramic sheet 3013 stacked together. The first piezoelectric ceramic sheet 3011 and the second piezoelectric ceramic sheet 3013 are conductors and can be used for conducting current. Diaphragm 3012 is a non-conductor and may not be used to conduct current.
The diaphragm 3012 is larger than the first and second piezoelectric ceramic pieces 3011 and 3013. The diaphragm 3012 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 sheet 3011 and the second piezoelectric ceramic sheet 3013 are disposed in the first region, so that the second region is exposed.
The first piezoelectric ceramic piece 3011 and the second piezoelectric ceramic piece 3013 are respectively electrically connected to an ac power source, such as the ac power source 200, for converting the electric energy output by the ac power source 200 into mechanical energy. The alternating current 200 is used to output an alternating voltage, and the alternating current 200 may include a first electrode 210 and a second electrode 220 having different potential values.
The first piezoelectric ceramic sheet 3011 has a first end face and a second end face opposite to each other, where the first end face is a face away from the diaphragm 3012, and the second end face is a face connected to the first region. The first end surface is electrically connected to the first electrode 210 of the ac power source 200, and the second end surface is electrically connected to the second electrode 220 of the ac power source 200.
The second piezoelectric ceramic sheet 3013 has a third end face and a fourth end face opposite to each other, where the third end face is a face connected to the first region, and the fourth end face is a face away from the diaphragm 3012. The third end surface is electrically connected to the second electrode 220 of the ac power supply 200, and the fourth end surface is electrically connected to the first electrode 210 of the ac power supply 200.
As shown in fig. 8 and 9, fig. 8 is a schematic structural view of the piezoelectric ceramic single body shown in fig. 4 in a first bending state, and fig. 9 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 alternating current power supply 200 may change with time along with the direction, the piezoelectric ceramic single bodies 301 may perform deformation motion along with the alternating change of the alternating voltage direction, and the deformation motion of the first piezoelectric ceramic single bodies 301 may cause ambient air to flow, thereby generating sound.
For example, as shown in fig. 8, when the alternating voltage direction of the ac power supply 200 is output from the first electrode 210 and returns to the second electrode 220, at this time, the first piezoelectric ceramic piece 3011 and the second piezoelectric ceramic piece 3013 polarize the polarization vector of the original disordered orientation preferentially along the electric field direction under the action of the electric field, because the direction of the applied electric field of the first piezoelectric ceramic piece 3011 is opposite to the direction of the applied electric field of the second piezoelectric ceramic piece 3013, the polarization direction of the first piezoelectric ceramic piece 3011 is opposite to the polarization direction of the second piezoelectric ceramic piece 3013, the polarization direction of the first piezoelectric ceramic piece 3011 is the same as the voltage direction of the ac power supply 200, and the first piezoelectric ceramic piece 3011 extends to bend the first piezoelectric ceramic piece 3011 toward the diaphragm 3012; the polarization direction of the second piezoelectric ceramic piece 3013 is opposite to the voltage direction of the ac power supply 200, the second piezoelectric ceramic piece 3013 is shortened, the second piezoelectric ceramic piece 3013 is bent in a direction away from the diaphragm 3012, and the diaphragm 3012 is also deformed under the action of the first piezoelectric ceramic piece 3011 and the second piezoelectric ceramic piece 3013, so that the first piezoelectric ceramic unit 301 assumes the first bending state.
As shown in fig. 9, when the alternating voltage direction of the ac power supply 200 is output from the second electrode 220 and returns to the first electrode 210, the polarization direction of the first piezoelectric ceramic piece 3011 is opposite to the voltage direction of the ac power supply 200, the first piezoelectric ceramic piece 3011 is shortened, the first piezoelectric ceramic piece 3011 is bent in a direction away from the diaphragm 3012, the second piezoelectric ceramic piece 3013 is extended, the second piezoelectric ceramic piece 3013 is bent in a direction toward the diaphragm 3012, and the diaphragm 3012 is also deformed under the action of the first piezoelectric ceramic piece 3011 and the second piezoelectric ceramic piece 3013, so that the first piezoelectric ceramic unit 301 assumes the second bending state.
The electronic device 100 can control the alternating voltage of the alternating current power source 200 to switch the first piezoelectric ceramic single body 301 between the first bending state and the second bending state, so as to control the first piezoelectric ceramic single body 301 to perform deformation motion.
Wherein, the deformation amplitude of the first piezoelectric ceramic unit 301 can be related to the voltage amplitude of the alternating voltage. For example, the deformation amplitude of the first piezoelectric ceramic element 301 may be proportional to the voltage amplitude of the alternating voltage. When the electronic device 100 controls the voltage amplitude of the alternating voltage of the alternating power supply 200 to increase, the deformation amplitude of the first piezoelectric ceramic single body 301 increases, 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 amplitude of the first piezoelectric ceramic element 301 is inversely proportional to the voltage amplitude of the alternating voltage, and in this case, the electronic device 100 may increase the deformation amplitude of the first piezoelectric ceramic element 301 by decreasing the voltage amplitude of the alternating voltage.
In the embodiment of the application, the first piezoelectric ceramic piece 3011 and the second piezoelectric ceramic piece 3013 are arranged in the first area, so that the second area of the diaphragm 3012 is exposed outside, the first area is deformed by the acting force applied by the first piezoelectric ceramic piece 3011 and the second piezoelectric ceramic piece 3013, and the second area keeps the original state without external force, so that the deformation amplitude of the diaphragm 3012 can be increased compared with the second area without exposure.
