[0046] Combine the following Figure 1-Figure 14 An electronic device according to an embodiment of the present invention is described.

[0047] The electronic device of the present application may include mobile terminals such as tablet computers, mobile phones, electronic watches, or electronic devices such as wearable devices. In order to illustrate the content of the present application, the following description will take a mobile phone as an example.

[0048] According to some embodiments of the present invention, the electronic device, such as Figure 1 As shown, it includes a first circuit board 1, a housing 2, a first piezoelectric element 3 and a second piezoelectric element 4. The first circuit board 1 may be provided with electronic components such as a processor for processing information transmitted to the first circuit board 1. The first circuit board 1 may be a motherboard in a mobile phone. The housing may be a housing 2 of a mobile phone. The first circuit board 1 is provided in the housing 2. The housing 2 is used to protect components such as a motherboard and a camera module inside the mobile phone. The housing 2 may include the middle frame of the mobile phone and the battery cover and other exposed parts.

[0049] The first piezoelectric element 3 and the second piezoelectric element 4 are arranged on the housing 2 at intervals, and the first piezoelectric element 3 and the second piezoelectric element 4 are respectively electrically connected to the first circuit board 1. The first piezoelectric element 3 and the second piezoelectric element 4 are piezoelectric materials with piezoelectric effect and inverse piezoelectric effect, and can realize the mutual conversion between electrical signals and force signals. Figure 12-14 As shown, the piezoelectric effect refers to the accumulation of charges of opposite polarity at both ends of a crystal when it is compressed or stretched in a certain direction, generating an electromotive force. The inverse piezoelectric effect is the opposite of the above process.

[0050] When the first piezoelectric element 3 and the second piezoelectric element 4 are deformed along with the shell 2, the first piezoelectric element 3 forms a first charge and a third charge with opposite polarities, and the second piezoelectric element 4 forms a second charge and a fourth charge with opposite polarities. The first circuit board 1 receives the first charge and the second charge, and the third charge and the fourth charge are connected to the reference ground. The polarities of the first charge and the second charge are opposite. For example, when a user pries the shell 2 of a mobile phone, the shell 2 will deform slightly. The slight deformation of the shell 2 will be sensed by the first piezoelectric element 3 and the second piezoelectric element 4 arranged on the shell 2 and deform along with the shell 2. At this time, the first piezoelectric element 3 produces a compressed deformation, and the second piezoelectric element 4 produces a stretched deformation, so that the polarities of the first charge and the second charge generated by the deformation of the first piezoelectric element 3 and the second piezoelectric element 4 are opposite. The first circuit board 1 receives the first charge and the second charge, and issues control instructions to the electronic device according to the first charge and the second charge.

[0051] In the present application, the first piezoelectric component 3 and the second piezoelectric component 4 are arranged on the housing 2 of the electronic device. By applying an external force to the housing 2, the first piezoelectric component 3 and the second piezoelectric component 4 can be deformed along with the housing 2, thereby causing the first piezoelectric component 3 and the second piezoelectric component 4 to deform to form a first charge and a second charge. The first circuit board 1 can output corresponding control instructions according to the received first charge and second charge. The present application can provide favorable conditions for the electronic device to have a new form of control instruction input.

[0052] At the same time, since the third charge formed by the first piezoelectric element 3 and the fourth charge formed by the second piezoelectric element 4 are connected to the reference ground, the first charge formed by the first piezoelectric element 3 and the second charge formed by the second piezoelectric element 4 are transmitted to the first circuit board 1 for processing. That is to say, the first piezoelectric element 3 and the second piezoelectric element 4 in the present application need to cooperate with each other so that the first charge and the second charge generated by the simultaneous deformation of the first piezoelectric element 3 and the second piezoelectric element 4 are jointly transported to the circuit board to trigger the control instruction of the electronic device. For example, the first piezoelectric element 3 is stretched to form a first charge with a positive polarity, and the second piezoelectric element 4 is compressed to form a second charge with a negative polarity. The first charge and the second charge are jointly transported to the circuit board for processing to trigger the control instruction of the electronic device. Therefore, the present application can prevent false triggering of electronic devices. For example, the first piezoelectric component 3 is deformed to form a first charge due to installation errors or human accidental touch, but the second piezoelectric component 4 is not deformed to generate a second charge. At this time, the circuit board only receives the first charge but not the second charge, and the control instruction of the electronic device will not be triggered. Or, the first piezoelectric component 3 and the second piezoelectric component 4 are mistakenly triggered at the same time, but the difference between the first charge amount formed by the first piezoelectric component 3 and the second charge amount formed by the second piezoelectric component 4 exceeds a predetermined range, and the control instruction of the electronic device will not be triggered.

[0053] Optionally, the first piezoelectric component 3 and the second piezoelectric component 4 are columnar structures. Since the columnar structure itself has a specific structure of a certain length, it is determined that it can sensitively sense the deformation of the shell 2, so that the columnar first piezoelectric component 3 and the second piezoelectric component 4 can generate first charges and second charges under conditions of slight deformation. Specifically, the shape of the first piezoelectric component 3 can be a prism with a certain length, and its cross-section can be a rectangle or other polygon, or the first piezoelectric component 3 can be cylindrical, and its cross-section can be circular. The shape of the first piezoelectric component 3 can refer to the shape of the first piezoelectric component 3, and the shape of the first piezoelectric component 3 can be different from the shape of the second piezoelectric component 4.

[0054] The first piezoelectric component 3 and the second piezoelectric component 4 are arranged on the side wall of the same side of the housing 2. Since the surface area of ​​the side wall of the housing 2 is small, when the user bends the housing 2 of the electronic device, the deformation degree of the side wall of the housing 2 is relatively large. The first piezoelectric component 3 and the second piezoelectric component 4 are arranged on the side wall of the housing 2, so that the first piezoelectric component 3 and the second piezoelectric component 4 can sense the deformation of the housing 2 to the greatest extent, which is conducive to generating the first charge and the second charge, thereby improving the sensitivity of the present application. At the same time, the first piezoelectric component 3 and the second piezoelectric component 4 are arranged on the same side of the side wall of the housing 2, so that the deformation of the first piezoelectric component 3 and the second piezoelectric component 4, one being stretched and the other being compressed, can be more easily controlled, reducing the difficulty of installing the first piezoelectric component 3 and the second piezoelectric component 4. The first piezoelectric component 3 and the second piezoelectric component 4 are arranged along the extension direction of the side wall of the shell 2. The arrangement of the first piezoelectric component 3 and the second piezoelectric component 4 themselves can be, for example, the first piezoelectric component 3 itself is arranged along the extension direction of the side wall, that is, the length direction of the side wall. The first piezoelectric component 3 can be parallel to the extension direction of the side wall of the shell 2, or can be inclined to the extension direction of the side wall of the shell 2. The arrangement of the second piezoelectric component 4 can be the same as the arrangement of the first piezoelectric component 3.

[0055] Alternatively, if Fig. 9 As shown, the first piezoelectric element 3 and the second piezoelectric element 4 are arranged opposite to each other, and the first piezoelectric element 3 and the second piezoelectric element 4 are parallel to each other, that is, in the width direction of the side wall of the housing 2, the first piezoelectric element 3 and the second piezoelectric element 4 are arranged side by side, and the first piezoelectric element 3 and the second piezoelectric element 4 can be parallel to the extension direction of the side wall of the housing 2. The above arrangement of the first piezoelectric element 3 and the second piezoelectric element 4 can make the deformation of the first piezoelectric element 3 opposite to that of the second piezoelectric element 4, and the arrangement is convenient. For example, when you place your hand on one side of the mobile phone and apply pressure from both ends of the mobile phone to the side where your hand is placed, the side wall of the shell 2 will bend. At this time, the side wall of the shell 2 close to the side where your hand is placed is under compression, while the side wall of the shell 2 away from the side where your hand is placed is under tension. The second piezoelectric component 4 arranged on the side wall close to the side where your hand is placed will be compressed, and the first piezoelectric component 3 arranged on the side wall away from the side where your hand is placed will be stretched, which facilitates the positioning of the first piezoelectric component 3 and the second piezoelectric component 4 and is conducive to generating charges of opposite polarities.

[0056] Alternatively, if Fig.10As shown, along the length direction of the side wall of the shell 2, the side wall of the shell 2 has a first side edge 7 and a second side edge 8 opposite to each other, and the first side edge 7 and the second side edge 8 are two boundaries of the side wall of the shell 2 in the length direction. The first end of the first piezoelectric element 3 is arranged close to the first side edge 7, and the second end of the first piezoelectric element 3 is arranged close to the second side edge 8, that is, the first piezoelectric element 3 is not parallel to the direction in which the side wall extends, and the first piezoelectric element 3 is arranged obliquely on the side wall. The first end of the second piezoelectric element 4 is arranged close to the second side edge 8, and the second end of the second piezoelectric element 4 is arranged close to the first side edge 7, that is, the second piezoelectric element 4 is not parallel to the direction in which the side wall extends, and the second piezoelectric element 4 is arranged obliquely on the side wall, and the first piezoelectric element 3 and the second piezoelectric element 4 are distributed on the side wall in an eight-shaped shape, which can facilitate the first piezoelectric element 3 and the second piezoelectric element 4 to produce different shapes. For example, torques in opposite directions are applied to both sides of the mobile phone, counterclockwise rotation torque is applied to the left end of the mobile phone, and clockwise rotation is applied to the right end of the mobile phone. At this time, the middle part of the mobile phone can be regarded as fixed, and the left end of the mobile phone is subjected to counterclockwise rotation, and combined with the tilt direction of the first piezoelectric element 3, it can be known that the first piezoelectric element 3 is in a compressed state. On the contrary, the right side of the mobile phone is subjected to clockwise rotation, and combined with the tilt direction of the second piezoelectric element 4, it can be known that the second piezoelectric element 4 is in a stretched state.

[0057] Optionally, along the length direction of the side wall of the shell 2, the middle part of the side wall of the shell 2 is the middle area, and the second end of the first piezoelectric component 3 and the first end of the second piezoelectric component 4 are arranged close to the middle area. When opposite torques are applied at both ends of the mobile phone, the first piezoelectric component 3 or the second piezoelectric component 4 can be avoided from being located in the part with smaller deformation in the middle of the mobile phone, thereby ensuring that the first piezoelectric component 3 and the second piezoelectric component 4 can produce deformation to the maximum extent, thereby ensuring the sensitivity of the first piezoelectric component 3 and the second piezoelectric component 4.

[0058] Furthermore, the first end of the first piezoelectric component 3 extends to the end of the side wall of the shell 2 in the length direction, and the second end of the second piezoelectric component 4 extends to the other end of the side wall of the shell 2 in the length direction, so that the first piezoelectric component 3 and the second piezoelectric component 4 almost occupy the entire length of the side wall, ensuring that the first piezoelectric component 3 and the second piezoelectric component 4 can reliably detect the deformation of the side wall of the shell 2.

[0059] Optionally, the electronic device also includes a third piezoelectric component 5 and a fourth piezoelectric component 6, the setting of the third piezoelectric component 5 is the same as the setting of the first piezoelectric component 3, the setting of the fourth piezoelectric component 6 is the same as the setting of the second piezoelectric component 4, the side wall on which the first piezoelectric component 3 and the second piezoelectric component 4 are set on the shell 2 is a first side wall 9, and the shell 2 has a second side wall 10 opposite to the first side wall 9, and the third piezoelectric component 5 and the fourth piezoelectric component 6 are arranged on the second side wall 10. That is to say, piezoelectric components are arranged on two opposite side walls of the mobile phone, so that the first piezoelectric component 3 and the third piezoelectric component 5 are symmetrically arranged, and the second piezoelectric component 4 and the fourth piezoelectric component 6 are symmetrically arranged. Increasing the number of piezoelectric components can ensure the sensitivity of the piezoelectric components in detecting deformation.

[0060] Alternatively, if Figure 7 and Figure 8 As shown, the electronic device includes at least two first piezoelectric elements 3 and at least two second piezoelectric elements 4. Along the length direction of the side wall of the housing 2, all the first piezoelectric elements 3 and all the second piezoelectric elements 4 are arranged in sequence, and any first piezoelectric element 3 and any second piezoelectric element 4 are adjacent to each other, and the adjacent ends of the first piezoelectric elements 3 and the second piezoelectric elements 4 are close to the first side edge 7 or the second side edge 8 of the side wall of the housing 2. In other words, there are multiple groups of first piezoelectric elements 3 and second piezoelectric elements 4 arranged in an eight-shaped arrangement and arranged side by side on the side wall, and all the first piezoelectric elements 3 and all the second piezoelectric elements 4 are distributed in a continuous W shape, as shown in FIG. Fig.11 As shown, the principle of all piezoelectric elements being stretched and compressed is the same as the above case where the first piezoelectric element 3 and the second piezoelectric element 4 are distributed in an eight-shaped shape on the side wall, and will not be repeated here. The above structure increases the number of piezoelectric elements, enables the piezoelectric elements to accurately obtain deformation information, and increases the response sensitivity of the present application.

[0061] Alternatively, if Figure 1 As shown, the electronic device further includes a flexible circuit board 11 and a sealant 12. The outer surface of the side wall of the housing 2 is provided with a first mounting groove 13 and a second mounting groove 14. The bottoms of the first mounting groove 13 and the second mounting groove 14 are provided with a first through hole 15 and a second through hole 16, respectively. The first piezoelectric component 3 is fixedly installed in the first mounting groove 13 through the sealant 12. The flexible circuit board 11 passes through the first through hole 15 and connects the first circuit board 1 and the first piezoelectric component 3. The sealant 12 can be set at the bottom of the first mounting groove 13. The first piezoelectric component 3 is bonded to the bottom of the first mounting groove 13 through the sealant 12. The flexible circuit board 11 passes through the sealant 12 and is connected to the first piezoelectric component 3.

[0062] The second piezoelectric element 4 is fixedly mounted in the second mounting groove 14 by the sealant 12, and the flexible circuit board 11 passes through the second through hole 16 and connects the first circuit board 1 and the second piezoelectric element 4. The sealant 12 can be arranged at the bottom of the second mounting groove 14, the second piezoelectric element 4 is bonded to the bottom of the second mounting groove 14 by the sealant 12, and the flexible circuit board 11 passes through the sealant 12 and is connected to the second piezoelectric element 4.

[0063] Optionally, at least a portion of the first piezoelectric element 3 and at least a portion of the second piezoelectric element 4 are exposed on the surface of the housing 2 , which can make the entire device look more beautiful.

[0064] Optionally, the first piezoelectric component 3 and the second piezoelectric component 4 are made of piezoelectric ceramics. Of course, the first piezoelectric component 3 and the second piezoelectric component 4 can also be other components that can generate or change electrical parameters according to deformation, such as piezoelectric transistors, quartz crystals, lithium niobate crystals, varistors or flat capacitors.

[0065] A control method of an electronic device, applied to the electronic device described above, the method comprising:

[0066] receiving input information formed by the first piezoelectric element 3 and the second piezoelectric element 4;

[0067] In response to the input information, output a control instruction for the electronic device;

[0068] The input information includes polarities of the first charge and the second charge formed by the first piezoelectric element 3 and the second piezoelectric element 4 , and / or magnitudes of the first charge and the second charge formed by the first piezoelectric element 3 and the second piezoelectric element 4 .

[0069] Among them, the input information includes the polarities of the first charge and the second charge formed by the first piezoelectric element 3 and the second piezoelectric element 4. It can be that when the first charge received is positive and the second charge is negative, the control instruction output to the electronic device is to open a specific program or function, such as the instruction issued to the electronic device at this time is to open a scope in a game, etc.; when the first charge received is negative and the second charge is positive, the control instruction output to the electronic device is to open another specific program or function, such as turning on the zoom function in the camera, etc.

[0070] The magnitudes of the first electric charge and the second electric charge formed by the first piezoelectric element 3 and the second piezoelectric element 4 can be such that when the first electric charge and the second electric charge are small, the degree of control instructions outputted to the electronic device is small, such as the aiming distance of the scope in the game is closer, etc.; when the first electric charge and the second electric charge are large, the degree of control instructions outputted to the electronic device is large, such as the aiming distance of the scope in the game is farther, etc.

[0071] It should be noted that the deformation magnitudes of the first piezoelectric element 3 and the second piezoelectric element 4 are positively correlated with the magnitudes of the electric charges. The greater the deformations of the first piezoelectric element 3 and the second piezoelectric element 4 are, the greater the electric charges generated are.

[0072] The present application embodiment provides a control device for an electronic device, which executes the control method for the electronic device described above, including:

[0073] A first module, the first module receiving input information formed by the first piezoelectric element and the second piezoelectric element;

[0074] a second module, wherein the second module outputs a control instruction for the electronic device in response to the input information;
