Description

Technical Field

[0001] This application belongs to the field of terminal technology, specifically relating to an electronic device. Background Technology

[0002] Typically, a vibration motor can be installed in an electronic device. When the electronic device needs to remind the user, it can control the vibration motor to vibrate, so that the vibration motor can also drive the electronic device to vibrate, thereby reminding the user through vibration.

[0003] However, since electronic devices may be small in size, the vibration motor installed in such devices may also be small in size. Therefore, the vibration of the vibration motor may be weak, resulting in a smaller amplitude of vibration of the electronic device.

[0004] This results in electronic devices being less effective at alerting users through vibration. Summary of the Invention

[0005] The purpose of this application is to provide an electronic device that can solve the problem that the effect of electronic devices reminding users through vibration is poor.

[0006] In a first aspect, embodiments of this application provide an electronic device comprising: a battery disposed within the body of the electronic device; and a piezoelectric component disposed within the body and in contact with the battery. When an electric field is applied to the piezoelectric component by the electronic device, the piezoelectric component drives the battery to move, thereby causing the electronic device to vibrate.

[0007] In this embodiment, the electronic device includes a battery disposed within its body and a piezoelectric component disposed within the body and in contact with the battery. When an electric field is applied to the piezoelectric component by the electronic device, the piezoelectric component can drive the battery to move, thereby causing the electronic device to vibrate. Since the electronic device can control the piezoelectric component to drive the heavier battery to move when it needs to alert the user through vibration, thus using the heavier battery to drive the vibration instead of a lighter vibration motor, the amplitude of the vibration can be increased, thereby enhancing the intensity of the vibration and improving the effectiveness of the vibration-based alert to the user.

Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0031] An electronic device provided in this application is described below with reference to the accompanying drawings.

[0032] To address this technical problem, the embodiments of this application employ the following technical solutions.

[0033] Figure 1 The illustration shows a possible structural diagram of an electronic device provided in an embodiment of this application, such as... Figure 1 As shown, the electronic device includes: a battery 10 disposed within the body 11 of the electronic device; and a piezoelectric component 12 disposed within the body 11 and in contact with the battery 10.

[0034] Optionally, in the embodiments of this application, the aforementioned electronic device may specifically be any of the following: wearable device, mobile phone, tablet computer, laptop computer, handheld computer, vehicle-mounted electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc., and may also be server, network attached storage (NAS), personal computer (PC), television (TV), ATM, or self-service machine, etc.

[0035] Wearable devices can include any of the following: smartwatches, smart bracelets, smart glasses, smart accessories, smart sneakers, smart straps, etc.

[0036] It should be noted that, Figure 1 This explanation uses wearable devices (such as smartwatches) as an example.

[0037] Optionally, in this embodiment of the application, when the electronic device is a wearable device, the main body 11 may specifically include: a display screen, a housing, and a wearing accessory. The display screen is connected to the housing to form the inner cavity of the main body 11, and the battery 10 and piezoelectric component 12 are both disposed within this inner cavity. The wearing accessory is connected to the housing, allowing the user to wear the electronic device; the wearing accessory may specifically be a wearing strap.

[0038] In this embodiment of the application, the battery 10 can be electrically connected to the piezoelectric component 12 (and / or electronic device), so that the battery 10 can provide power to the piezoelectric component 12 (and / or electronic device).

[0039] Optionally, in this embodiment of the application, the battery 10 can be electrically connected to the piezoelectric component 12 (and / or the motherboard of the electronic device) via a flexible printed circuit (FPC), so that the electronic device can apply an electric field to the piezoelectric component 12 via the battery 10.

[0040] In this embodiment of the application, the piezoelectric component 12 can be electrically connected to the motherboard of the electronic device.

[0041] In this embodiment, when an electronic device applies an electric field to the piezoelectric component 12, the piezoelectric component 12 drives the battery 10 to move, thereby causing the electronic device to vibrate.

[0042] When an electronic device applies an electric field to the piezoelectric component 12, the state of the piezoelectric component 12 can change to drive the battery 10 to move.

[0043] Optionally, in one possible implementation of this application embodiment, the piezoelectric component 12 can specifically be a piezoelectric unit. The piezoelectric unit can be a piezoelectric sheet made of a piezoelectric material (e.g., piezoelectric ceramics such as barium titanate (BaTiO3) or lead zirconate titanate (PZT)). The piezoelectric unit can include a first electrode, a second electrode, and a crystal, with the crystal disposed between the first and second electrodes. The first and second electrodes have different polarities, so that when an electric field is applied to the piezoelectric unit by an electronic device, the state of the piezoelectric unit can change, causing the piezoelectric unit to deform and vibrate, thereby driving the battery 10 to move.

[0044] For example, Figure 2 A schematic diagram of a possible structure for the piezoelectric component 12 is shown. For example... Figure 2As shown, the piezoelectric component 12 is a piezoelectric unit, which includes a first electrode 13, a second electrode 14 and a crystal 15, with the crystal 15 disposed between the first electrode 13 and the second electrode 14.

[0045] Combination Figure 2 ,like Figure 3 As shown, the electronic device can apply an electric field (i.e., the polarization direction of the piezoelectric unit) to the piezoelectric unit via the battery 10, so that internal stress can be generated inside the crystal 15. Under the action of this internal stress, the crystal 15 can expand and deform, thereby changing the state of the piezoelectric unit, thus placing the piezoelectric unit in a certain state, which can then drive the battery 10 to move; or, in combination with... Figure 2 ,like Figure 4 As shown, the electronic device can apply an electric field in another direction (i.e., the opposite direction to the polarization direction of the piezoelectric unit) to the piezoelectric unit through the battery 10, so that the crystal 15 can generate an internal compressive force, and the crystal 15 can shrink and deform under the action of the internal compressive force, so that the state of the piezoelectric unit changes, that is, the piezoelectric unit is in another state, and thus the battery 10 can be driven to move.

[0046] It is understood that electronic devices can alternately apply electric fields in different directions to the piezoelectric unit through the battery 10, so that the crystal 15 can alternately be in different states. This can cause the piezoelectric unit to vibrate, thereby driving the battery 10 to reciprocate, and thus causing the electronic device to vibrate.

[0047] Optionally, in another possible implementation of this application embodiment, the piezoelectric component 12 may include a piezoelectric unit and an amplitude amplification unit connected to the piezoelectric unit. The amplitude amplification unit amplifies the amplitude of the vibration of the piezoelectric unit, so that when an electric field is applied to the piezoelectric unit by an electronic device, the piezoelectric unit can deform, thus vibrating. The amplitude amplification unit can then amplify the amplitude of the vibration of the piezoelectric unit to drive the movement of the battery 10.

[0048] It is understandable that the amplitude amplification unit can amplify the amplitude of the vibration of the piezoelectric unit, thereby amplifying the amplitude of the vibration of the battery 10, and further amplifying the amplitude of the vibration of the electronic device.

[0049] In this embodiment, the piezoelectric component 12 and the battery 10 can be regarded as a whole, and the weight of the whole is relatively large. In this way, when the electronic device applies an electric field to the piezoelectric component 12, the heavy whole can vibrate, thereby increasing the amplitude of the vibration of the electronic device and enhancing the amount of vibration of the electronic device.

[0050] The electronic device provided in this application includes a battery disposed within the body of the electronic device and a piezoelectric component disposed within the body and in contact with the battery. When an electric field is applied to the piezoelectric component by the electronic device, the piezoelectric component can drive the battery to move, thereby causing the electronic device to vibrate. Since the electronic device can control the piezoelectric component to drive the heavier battery to move when it needs to remind the user through vibration, the vibration can be driven by the heavier battery, rather than by a lighter vibration motor. Therefore, the amplitude of the vibration can be increased, thereby enhancing the amount of vibration and improving the effectiveness of the vibration-based reminder to the user.

[0051] Furthermore, in this embodiment, a piezoelectric component can be installed in the electronic device to replace the vibration motor in the related technology through the combination of the piezoelectric component and the battery, without the need for an additional counterweight, thus saving internal space in the electronic device. Simultaneously, since there is no need to install a vibration motor within the device itself, the interference of magnets, coils, and other components in the vibration motor with the electronic devices within the device can be avoided.

[0052] The following will use two different examples to illustrate the piezoelectric component, which includes a piezoelectric unit and an amplitude amplification unit.

[0053] Example 1

[0054] Optionally, in the embodiments of this application, combined with Figure 1 ,like Figure 5 As shown, the piezoelectric component 12 includes: a first elastic unit 121, the first surface of which is connected to the inner wall of the body 11, the second surface of which is in contact with the battery 10, and the second surface being away from the first surface; and a first piezoelectric unit 122, which is disposed on the first elastic unit 121.

[0055] It is understood that in this example, the first elastic unit 121 is an amplitude amplification unit, and the first piezoelectric unit 122 is a piezoelectric unit.

[0056] Further optionally, in this embodiment, the first elastic unit 121 can specifically be an elastic plate made of an elastic material. The elastic material can include any of the following: metal, rubber, plastic, etc.

[0057] Further optionally, in the embodiments of this application, when the electronic device is a wearable device, the first surface of the first elastic unit 121 can be connected to the inner wall of the housing opposite to the display screen, that is, the inner wall of the body 11 is the inner wall of the housing opposite to the display screen.

[0058] Alternatively, in this embodiment, the first surface of the first elastic unit 121 can be connected to the inner wall of the body 11 via a connector. Specifically, the connector can be a positioning post.

[0059] For example, combined with Figure 5 ,like Figure 6 As shown, the first surface (i.e. the lower surface in the figure) of the first elastic unit 121 is connected to the inner wall of the body 11 (e.g., the bottom inner wall 17 of the body 11 in the figure) through the positioning post 16.

[0060] Further, optionally, in this embodiment, the second surface of the first elastic unit 121 can directly contact the battery 10 (i.e., as shown in the image). Figure 5 As shown), or, the first elastic unit 121 can be replaced by other components (e.g., the first piezoelectric unit 122, i.e., as shown). Figure 6 The first gasket (as shown in the example below, or the first gasket in the following embodiments) contacts the battery 10.

[0061] Further optionally, in this embodiment of the application, the first piezoelectric unit 122 may specifically be a piezoelectric sheet made of a piezoelectric material (e.g., piezoelectric ceramic); the first piezoelectric unit 122 may be fixed to the first elastic unit 121 with adhesive.

[0062] Specifically, the first piezoelectric unit 122 can be fixed to the central region of the first surface (and / or the second surface) of the first elastic unit 121 with adhesive. It should be noted that the "central region" can be understood as the area within a predetermined range of the center of the first surface (and / or the second surface) of the first elastic unit 121.

[0063] Further optionally, in the embodiments of this application, the first piezoelectric unit 122 may include one or more piezoelectric units.

[0064] In the case where the first piezoelectric unit 122 includes multiple piezoelectric units, the multiple piezoelectric units can be all disposed on the same surface of the first piezoelectric unit 122, or they can be disposed on non-adjacent surfaces of the first piezoelectric unit 122 respectively.

[0065] It is understood that when the first piezoelectric unit 122 is disposed on the first surface of the first piezoelectric unit 122, the second surface of the first elastic unit 121 can directly contact the battery 10.

[0066] In this embodiment of the application, when an electronic device applies an electric field to the first piezoelectric unit 122, the first piezoelectric unit 122 drives the first elastic unit 121 to undergo elastic deformation, so that the first elastic unit 121 drives the battery 10 to move.

[0067] It is understood that when an electronic device applies an electric field to the first piezoelectric unit 122, the state of the first piezoelectric unit 122 can change to drive the first elastic unit 121 to undergo elastic deformation.

[0068] Alternatively, in this embodiment of the application, the first piezoelectric unit 122 may change its state on the plane where the first elastic unit 121 is located.

[0069] When the first piezoelectric unit 122 is in a certain state, the first piezoelectric unit 122 can drive the first elastic unit 121 to undergo elastic deformation in one direction, thereby the first elastic unit 121 can drive the battery 10 to move in that direction.

[0070] When the first piezoelectric unit 122 is in another state, the first piezoelectric unit 122 can drive the first elastic unit 121 to undergo elastic deformation in another direction, so that the first elastic unit 121 can drive the battery 10 to move in that other direction.

[0071] It is understandable that since the size of the first elastic unit 121 has not changed, but the size of the first piezoelectric unit 122 has changed when the state of the first piezoelectric unit 122 changes, the first piezoelectric unit 122 will drive the first elastic unit 121 to undergo elastic deformation in different directions.

[0072] Thus, it can be seen that since the first piezoelectric unit can drive the battery to move through the first elastic unit, that is, the amplitude of the battery vibration can be increased through the first elastic unit, thereby enhancing the amount of vibration of the electronic device. Therefore, the effect of the electronic device reminding the user through vibration can be improved.

[0073] The following example will be taken with the first piezoelectric unit 122 comprising multiple piezoelectric units.

[0074] Optionally, in the embodiments of this application, combined with Figure 5 ,like Figure 7 As shown, the first piezoelectric unit 122 includes: a first piezoelectric element 1221 disposed on the first surface of the first elastic unit 121; and a second piezoelectric element 1222 disposed on the second surface of the first elastic unit 121.

[0075] It should be noted that, in order to more clearly illustrate the first piezoelectric unit 122, Figure 8 An exploded view of the piezoelectric component 12 is shown. Figure 8As shown, the first piezoelectric unit 122 includes: a first piezoelectric element 1221 disposed on the first surface of the first elastic unit 121, and a second piezoelectric element 1222 disposed on the second surface of the first elastic unit 121.

[0076] Optionally, in this embodiment, the first piezoelectric element 1221 can be a piezoelectric sheet made of a piezoelectric material (e.g., piezoelectric ceramic); the first piezoelectric element 1221 can be fixed to the central region of the first surface of the first elastic unit 121 with adhesive. The second piezoelectric element 1222 can be a piezoelectric sheet made of a piezoelectric material (e.g., piezoelectric ceramic); the second piezoelectric element 1222 can be fixed to the central region of the second surface of the first elastic unit 121 with adhesive.

[0077] It is understood that the first piezoelectric element 1221 and the second piezoelectric element 1222 can be symmetrical with respect to the first elastic element 121.

[0078] Further, optionally, in the embodiments of this application, such as Figure 9 As shown, the first piezoelectric element 1221 has the same polarity as the second piezoelectric element 1222, and the first piezoelectric element 1221 and the second piezoelectric element 1222 can be connected by a connector (e.g., a circuit board), and the first piezoelectric element 1221 and the second piezoelectric element 1222 have the same circuit.

[0079] Thus, when an electric field is applied to the first piezoelectric element 1221 and the second piezoelectric element 1222, the state of the first piezoelectric element 1221 is different from the state of the second piezoelectric element 1222.

[0080] In this embodiment of the application, when the first piezoelectric element 1221 is in the first state, the second piezoelectric element 1222 is in the second state to drive the first elastic unit 121 to move in the first direction.

[0081] Further optionally, in the embodiments of this application, the first state can be a state of expansion deformation, and the second state can be a state of contraction deformation.

[0082] For example, combined with Figure 7 ,like Figure 10 As shown, if the first piezoelectric element 1221 is in the first state, the size of the first piezoelectric element 1221 on the first surface of the first elastic unit 121 will increase. If the second piezoelectric element 1222 is in the second state, the size of the second piezoelectric element 1222 on the second surface of the first elastic unit 121 will decrease. Therefore, the first elastic unit 121 can move in the first direction (e.g., direction 18), thereby driving the battery 10 to move in direction 18.

[0083] In this embodiment of the application, when the first piezoelectric element 1221 is in the second state, the second piezoelectric element 1222 is in the first state to drive the first elastic unit 121 to move in a second direction; the second direction is opposite to the first direction.

[0084] For example, combined with Figure 7 ,like Figure 11 As shown, if the first piezoelectric element 1221 is in the second state, the size of the first piezoelectric element 1221 on the first surface of the first elastic unit 121 will become smaller. If the second piezoelectric element 1222 is in the first state, the size of the second piezoelectric element 1222 on the second surface of the first elastic unit 121 will become larger. Therefore, the first elastic unit 121 can move in the second direction (e.g., direction 19), thereby driving the battery 10 to move in direction 19.

[0085] It is understood that the first piezoelectric element 1221 and the second piezoelectric element 1222 can alternately be in different states so that the first elastic unit 121 can reciprocate in different directions, thereby driving the battery 10 to reciprocate in different directions, and thus causing the electronic device to vibrate.

[0086] Thus, since different piezoelectric elements can be set on different surfaces of the first elastic unit that are far apart from each other, the different piezoelectric elements can be controlled to be in different states to drive the first elastic unit to move. Therefore, the stroke of the first elastic unit can be increased, thereby increasing the stroke of the battery. In this way, the amplitude of the vibration of the electronic device can be increased, thereby enhancing the amount of vibration of the electronic device.

[0087] Optionally, in the embodiments of this application, combined with Figure 7 ,like Figure 12 As shown, the above-mentioned electronic device further includes a first gasket 20, which is disposed between the second surface of the first elastic unit 121 and the battery 10.

[0088] It is understood that one side of the first pad 20 can contact the second piezoelectric element 1222, and the other side of the first pad 20 can contact the battery 10.

[0089] Further optionally, in this embodiment of the application, the shape of the first gasket 20 can be convex; one end of the first gasket 20 can be connected to the second surface of the first elastic unit 121 by adhesive, and the other end can be connected to the battery 10 by adhesive.

[0090] Specifically, one end of the first gasket 20 can be connected to the first piezoelectric element 1221 on the second surface of the first elastic unit 121 by adhesive, so as to connect with the second surface of the first elastic unit 121.

[0091] Thus, it can be seen that since a first pad can be placed between the second surface of the first elastic unit and the battery, the stability of the battery movement can be improved.

[0092] Example 2

[0093] Optionally, in the embodiments of this application, combined with Figure 1 ,like Figure 13 As shown, the piezoelectric component 12 includes: a second piezoelectric unit 123, which is connected to the inner wall of the body 11; and a second elastic unit 124, which is disposed on the second piezoelectric unit 123 and is in contact with the battery 10.

[0094] It is understood that in this example, the second piezoelectric unit 123 is a piezoelectric unit, and the second elastic unit 124 is an amplitude amplification unit.

[0095] Further optionally, in the embodiments of this application, the second piezoelectric unit 123 may specifically be a piezoelectric sheet made of piezoelectric material (e.g., piezoelectric ceramic).

[0096] Alternatively, in this embodiment, when the electronic device is a wearable device, the second piezoelectric unit 123 can be connected to the inner wall of the housing opposite to the display screen, that is, the inner wall of the body 11 is the inner wall of the housing opposite to the display screen.

[0097] Alternatively, in this embodiment, the second piezoelectric unit 123 can be connected to the inner wall of the body 11 via other elastic units (e.g., positioning posts, or the third elastic unit in the following embodiments).

[0098] Specifically, when the piezoelectric component 12 is the second piezoelectric unit 123, the second piezoelectric unit 123 can be connected to the inner wall of the body 11 through a positioning post; when the piezoelectric component 12 includes the second piezoelectric unit 123 and other piezoelectric units (the third elastic unit in the following embodiments), the second piezoelectric unit 123 can be connected to the inner wall of the body 11 through the other piezoelectric units.

[0099] Further optionally, in this embodiment, the second elastic unit 124 can specifically be an elastic sheet made of an elastic material; wherein, the elastic material can include any of the following: metal, rubber, plastic, etc. The second elastic unit 124 can be fixed to one side (e.g., the third side in the following embodiment) of the second piezoelectric unit 123 by adhesive.

[0100] Specifically, the projection of the center of the second elastic unit 124 onto the second piezoelectric unit 123 can coincide with the center of the second piezoelectric unit 123.

[0101] Optionally, in the embodiments of this application, combined with Figure 13 ,like Figure 14 As shown, the second elastic unit 124 includes: a first elastic portion 1241, which is attached to the second piezoelectric unit 123; and a second elastic portion 1242, which is connected to the first elastic portion 1241 and is in contact with the battery 10.

[0102] Optionally, in this embodiment, the first elastic portion 1241 may be integrally formed with the second elastic portion 1242. The angle between the first elastic portion 1241 and the second elastic portion 1242 is not 0°. It can be understood that the second elastic unit 124, formed by the first elastic portion 1241 and the second elastic portion 1242, has a cymbal-shaped shape.

[0103] The increase in the amplitude of battery vibration caused by the second elastic unit can be adjusted by adjusting the angle (bending angle) between the first elastic part 1241 and the second elastic part 1242.

[0104] Optionally, in this embodiment, the first elastic portion 1241 may include two elastic portions that are symmetrical about the center of the second piezoelectric unit 123. The projection of the second elastic portion 1242 onto the second piezoelectric unit 123 may coincide with the center of the second piezoelectric unit 123.

[0105] Optionally, in the embodiments of this application, combined with Figure 13 ,like Figure 15 As shown, the piezoelectric component 12 further includes a second gasket 125, which is disposed between the first elastic portion 1241 and the second piezoelectric unit 123.

[0106] Thus, it can be seen that since a second gasket can be placed between the first elastic part and the second piezoelectric unit, the stability of the elastic deformation of the second elastic unit can be improved.

[0107] In this embodiment of the application, when an electronic device applies an electric field to the second piezoelectric unit 123, the second piezoelectric unit 123 drives the second elastic unit 124 to undergo elastic deformation, so that the second elastic unit 124 drives the battery 10 to move.

[0108] It is understood that when an electronic device applies an electric field to the second piezoelectric unit 123, the state of the second piezoelectric unit 123 can change to drive the second elastic unit 124 to undergo elastic deformation.

[0109] When the second piezoelectric unit 123 is in a certain state, the second piezoelectric unit 123 can drive the second elastic unit 124 to undergo elastic deformation in one direction, thereby the second elastic unit 124 can drive the battery 10 to move in that direction.

[0110] When the second piezoelectric unit 123 is in another state, the second piezoelectric unit 123 can drive the second elastic unit 124 to undergo elastic deformation in another direction, so that the second elastic unit 124 can drive the battery 10 to move in that other direction.

[0111] It is understood that since the size of the second piezoelectric unit 123 changes when the state of the second piezoelectric unit 123 changes, the second piezoelectric unit 123 will drive the second elastic unit 124 disposed on the second piezoelectric unit 123 to undergo elastic deformation in different directions.

[0112] Thus, it can be seen that when the filling of the second piezoelectric unit changes, the second piezoelectric unit can drive the battery to move through the second elastic unit. That is, the amplitude of the battery vibration can be increased through the second elastic unit, thereby enhancing the amount of vibration of the electronic device. Therefore, the effect of the electronic device reminding the user through vibration can be improved.

[0113] Of course, the piezoelectric component 12 may also include other elastic units to further increase the amplitude of the vibration of the battery, as will be illustrated in the following examples.

[0114] Optionally, in the embodiments of this application, combined with Figure 13 ,like Figure 16 As shown, the second elastic unit 124 is disposed on the third surface of the second piezoelectric unit 123; the piezoelectric assembly 12 further includes a third elastic unit 126, which is disposed on the fourth surface of the second piezoelectric unit 123. The third elastic unit 126 is in contact with the inner wall of the body 11, and the fourth surface is away from the third surface.

[0115] It should be noted that, in order to more clearly illustrate the third elastic element 126, Figure 17 A schematic diagram of the piezoelectric component 12 is shown. Figure 17 As shown, the second elastic unit 124 is disposed on the third surface of the second piezoelectric unit 123; the piezoelectric assembly 12 further includes a third elastic unit 126 disposed on the fourth surface of the second piezoelectric unit 123; wherein the fourth surface is away from the third surface.

[0116] It is understood that the second piezoelectric unit 123 can be connected to the inner wall of the body 11 through the third elastic unit 126.

[0117] Further optionally, in this embodiment, the third elastic unit 126 can specifically be an elastic sheet made of an elastic material; wherein the elastic material can include any of the following: metal, rubber, plastic, etc. The third elastic unit 126 can be fixed to the fourth surface of the second piezoelectric unit 123 with adhesive.

[0118] Specifically, the projection of the center of the third elastic unit 126 onto the second piezoelectric unit 123 can coincide with the center of the second piezoelectric unit 123.

[0119] Optionally, in this embodiment of the application, the third elastic unit 126 and the second elastic unit 124 are symmetrically arranged with respect to the second piezoelectric unit 123.

[0120] Thus, it can be seen that since the second and third elastic units can be symmetrically arranged on different surfaces of the second piezoelectric unit, the stability of battery movement can be improved.

[0121] Optionally, in this embodiment of the application, the third elastic unit 126 includes: a third elastic portion that is in contact with the fourth surface; and a fourth elastic portion that is in contact with the inner wall of the body 11.

[0122] It should be noted that the descriptions of the third and fourth elastic portions can be found in the detailed descriptions of the first and second elastic portions in the above embodiments, and will not be repeated here in the embodiments of this application.

[0123] Optionally, in this embodiment of the application, the piezoelectric component 12 further includes a third gasket, which is disposed between the third elastic portion and the second piezoelectric unit 123.

[0124] Thus, it can be seen that by placing a second gasket between the third elastic part and the second piezoelectric unit, the stability of the elastic deformation of the third elastic unit can be improved.

[0125] In this embodiment of the application, when an electronic device applies an electric field to the second piezoelectric unit 123, the second piezoelectric unit 123 drives the second elastic unit 124 to undergo elastic deformation in a third direction, and drives the third elastic unit 126 to undergo elastic deformation in a fourth direction; the fourth direction is opposite to the third direction.

[0126] Further, optionally, in the embodiments of this application, such as Figure 18As shown, if the second piezoelectric unit 123 is in a certain state, the size of the second piezoelectric unit 123 will increase. The second piezoelectric unit 123 can drive the second elastic unit 124 to undergo elastic deformation in a third direction (e.g., direction 21) and drive the third elastic unit 126 to undergo elastic deformation in a fourth direction (e.g., direction 22), thereby driving the battery 10 to move in direction 21.

[0127] Further, optionally, in the embodiments of this application, such as Figure 19 As shown, if the second piezoelectric unit 123 is in another state, the size of the second piezoelectric unit 123 will become smaller. The second piezoelectric unit 123 can drive the second elastic unit 124 to undergo elastic deformation in a third direction (e.g., direction 23) and drive the third elastic unit 126 to undergo elastic deformation in a fourth direction (e.g., direction 24), thereby driving the battery 10 to move in direction 23.

[0128] It is understood that the second piezoelectric unit 123 can be in different states alternately, so that the second elastic unit 124 and the third elastic unit 126 can reciprocate in different directions, thereby driving the battery 10 to reciprocate in different directions, and thus causing the electronic device to vibrate.

[0129] Thus, since different elastic units can be placed on different surfaces of the second piezoelectric unit, when the second piezoelectric unit deforms, the second piezoelectric unit can drive the different elastic units to undergo elastic deformation in different directions. Therefore, the stroke of the battery movement can be increased, thereby increasing the amplitude of vibration of the electronic device.
