[0002] With the rapid development of electronic devices, the functions of electronic devices are becoming more and more abundant, and the gaming experience of electronic devices is becoming more and more popular among users.

[0003] To make gaming on electronic devices more immersive and realistic, vibration motors are often installed within these devices. These motors allow users to experience different vibration feedback and determine their target location. Currently, to further enhance the user's gaming experience, multiple vibration motors are often installed in different locations within an electronic device. These motors are independently controlled to provide users with a 3D vibration experience.

[0004] However, multiple vibration motors tend to occupy more space in the electronic device and increase the cost of the electronic device. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem in the prior art that multiple vibration motors occupy a large amount of space in the electronic device, resulting in a high cost of the electronic device.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects and are not used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of this application can be implemented in an order other than those illustrated or described herein. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] The following is combined with Figure 1-6 , the electronic device provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0022] like Figure 1-3 As shown, the electronic device described in the embodiment of the present application may specifically include: a device body 1, a piezoelectric module 2 and a vibration motor 3, wherein the piezoelectric module 2 and the vibration motor 3 are both arranged in the device body 1, wherein one end of the piezoelectric module 2 can be set in the first area of ​​the vibration motor 3, and the other end can be set in the second area of ​​the vibration motor 3, the second area can be set around the first area, and the second area is close to the circumferential edge of the vibration motor 3; the piezoelectric module 2 can be fixedly connected to the vibration motor 3, and the piezoelectric module 2 can generate deformation when energized and drive the vibration motor 3 to move relative to the device body 1.

[0023] In the embodiment of the present application, one end of the piezoelectric module 2 is disposed in the first region of the vibration motor 3, and the other end is disposed in the second region of the vibration motor 3. Since the second region is disposed around the first region and is close to the circumferential edge of the vibration motor 3, the piezoelectric module 2, when energized, can drive the vibration motor 3 to move relative to the device body 1, so that the vibration motor 3 tilts relative to the device body 1, allowing the vibration motor 3 to generate vibration components in multiple directions, providing the user with a 3D vibration sensation. In the embodiment of the present application, only one vibration motor 3 is required within the electronic device, which can save internal space and reduce the cost of the electronic device. Moreover, by controlling the tilt of the vibration motor 3 relative to the device body 1, resonance between the vibration motor 3 and the camera motor can be avoided.

[0024] The electronic devices described in the embodiments of this application include, but are not limited to, mobile phones, computers, tablets, and smart wearable devices. The device body 1 described in the embodiments of this application is the main structure of the electronic device, which may specifically include a frame, a housing, a camera module, a processor, a power module, etc., and is not specifically limited in the embodiments of this application.

[0025] The piezoelectric module 2 described in the embodiments of the present application can be a driving structure that can be used to provide power. Specifically, the piezoelectric module 2 can have an energized state and an unenergized state. In the energized state, the piezoelectric module 2 can produce deformation; in the unenergized state, the piezoelectric module 2 can not produce deformation. Furthermore, the piezoelectric module 2 is fixedly connected to the vibration motor 3 and can drive the vibration motor 3 to move when it produces deformation.

[0026] Specifically, the piezoelectric module 2 can be fixedly connected to the vibration motor 3 by bonding, bolting, etc., and can be specifically configured according to actual needs. This embodiment of the present application does not specifically limit this.

[0027] Furthermore, the piezoelectric module 2 can be arranged at the top or bottom of the vibration motor 3, etc., and can be specifically arranged according to actual needs. The embodiment of the present application does not make any specific limitation to this.

[0028] The vibration motor 3 described in the embodiment of the present application is disposed within the electronic device and can drive the electronic device to vibrate, such that a user can feel the vibration while holding the electronic device. Specifically, the vibration direction of the vibration motor 3 can be parallel to the centerline of the vibration motor 3. For example, the vibration axis of the vibration motor 3 can be disposed along the thickness, width, or length of the device body 1.

[0029] Specifically, the second region can be located near the circumferential edge of the vibration motor 3. In this way, when energized, the piezoelectric module 2 can deform and drive the second region of the vibration motor 3 to move, thereby driving the circumferential edge of the vibration motor 3 to move relative to the device body 1. The second region can be arranged around the first region. For example, the first region can be the center region of the vibration motor 3, or an area near the center region of the vibration motor 3. The specific arrangement can be based on actual needs and is not specifically limited in this embodiment of the present application.

[0030] Furthermore, one end of the piezoelectric module 2 is arranged in the first area of ​​the vibration motor 3, and the other end is arranged in the second area of ​​the vibration motor 3. In this way, the piezoelectric module 2 can generate deformation when powered on and drive the circumferential edge of the vibration motor 3 to move relative to the device body 1, so that the vibration motor 3 can be tilted relative to the device body 1. Furthermore, the vibration motor 3 can generate vibration components in multiple directions, so that the user can feel vibrations in multiple directions and thus generate a sense of direction.

[0031] For example, Figure 6 As shown, the piezoelectric module 2 is in the unpowered state. The piezoelectric module 2 may not generate driving force, and the vibration motor 3 may have a main vibration axis of the Z-axis, so that the user can feel vibration in the Z-axis direction. In this scenario, the vibration motor 3 may only vibrate along the Z-axis direction, and the user may only feel the vibration and the change in the vibration frequency. The Z-axis direction may be the thickness direction of the electronic device, and the Z-axis direction may be perpendicular to the back panel of the electronic device.

[0032] Specifically, if Figure 4 As shown, the piezoelectric module 2 can be in the power-on state, and the piezoelectric module 2 can generate a driving force, so that the vibration motor 3 is tilted at a certain angle relative to the device body 1. In this way, the vibration axis of the vibration motor 3 can change, and a vibration component in the Z-axis direction and a vibration component in the X-axis direction can be generated. The vibration component in the Z-axis direction can allow the user to feel the vibration in the Z-axis direction; the vibration component in the X-axis direction can allow the user to feel the vibration of the electronic device to the right, and thus allow the user to feel a sense of direction to the right.

[0033] Specifically, if Figure 5 As shown, the vibration of the vibration motor 3 can generate a vibration component in the Z-axis direction and a vibration component in the X-axis direction. The vibration component in the X-axis direction can also allow the user to feel the vibration of the electronic device to the left, thereby allowing the user to feel a sense of direction to the left.

[0034] Furthermore, the vibration of the vibration motor 3 can also generate a vibration component in the Z-axis direction and a vibration component in the Y-axis direction, so that the user can feel the forward or backward direction. For details, please refer to Figure 4 and Figure 5 The present invention does not specifically limit this.

[0035] Optionally, the number of the piezoelectric modules 2 may be at least two; the at least two piezoelectric modules 2 may be disposed on the same side of the vibration motor 3 , and the at least two piezoelectric modules 2 may be spaced apart along the circumference of the vibration motor 3 .

[0036] In the embodiment of the present application, at least two piezoelectric modules 2 are arranged at intervals along the circumference of the vibration motor 3, so that the piezoelectric module 2 can drive the motor at multiple positions in the circumference, providing the user with a full range of 3D vibration sensations.

[0037] Specifically, the number of piezoelectric modules 2 can be two, four, five, or six, etc., and can be set according to actual needs. The embodiment of the present application does not specifically limit this. The purpose of providing multiple piezoelectric modules 2 is to enable the vibration motor 3 to tilt in different directions, thereby providing a 3D vibration sensation to the user. The vibration motor 3 can be controlled to change its tilt direction over time through coding and control of the circuit board 11, thereby enabling more flexible control of the tilt direction of the vibration motor 3.

[0038] Specifically, at least two piezoelectric modules 2 may be evenly arranged along the circumference of the vibration motor 3 to further improve the structural stability of the electronic device.

[0039] Optionally, the device body 1 may include a circuit board 11, and the piezoelectric module 2 may include: a piezoelectric layer 21, a first electrode 22 and a second electrode 23; the first electrode 22 and the second electrode 23 may be respectively arranged on opposite sides of the piezoelectric layer 21; the circuit board 11 may be electrically connected to the first electrode 22 and the second electrode 23, respectively, so as to transmit electrical signals to the piezoelectric layer 21 through the first electrode 22 and the second electrode 23.

[0040] In an embodiment of the present application, the circuit board 11 is electrically connected to the first electrode 22 and the second electrode 23, respectively. Since the first electrode 22 and the second electrode 23 are respectively arranged on opposite sides of the piezoelectric layer 21, it is convenient for the circuit board 11 to transmit electrical signals to the piezoelectric layer 21 through the first electrode 22 and the second electrode, so that the piezoelectric layer 21 is energized and deformed.

[0041] Specifically, the first electrode 22 and the second electrode 23 have opposite polarities. For example, the first electrode 22 is a positive electrode and the second electrode 23 is a negative electrode; alternatively, the first electrode 22 is a negative electrode and the second electrode 23 is a positive electrode. The first electrode 22 can be a copper electrode, a silver electrode, or a nickel electrode, and the second electrode 23 can be a copper electrode, a silver electrode, or a nickel electrode, etc. The selection can be based on actual needs and is not specifically limited in this embodiment of the present application.

[0042] Specifically, the piezoelectric layer 21 can be a piezoelectric sheet, a piezoelectric rod, or a piezoelectric block made of a piezoelectric material. The piezoelectric material can include organic piezoelectric materials, inorganic ceramic piezoelectric materials, single crystal piezoelectric materials, lead-free piezoelectric materials, etc. The specific selection can be based on actual needs and is not specifically limited in the present embodiment.

[0043] Specifically, the circuit board 11 may be electrically connected to the vibration motor 3 so that the circuit board 11 supplies power to the vibration motor 3 , causing the vibration motor 3 to vibrate when powered.

[0044] Furthermore, the circuit board 11 can be a flexible circuit board or a rigid circuit board, etc., and can be specifically configured according to actual needs, and the embodiment of the present application does not make any specific limitations on this.

[0045] Specifically, the first electrode 22 and the second electrode 23 can be fixed on both sides of the piezoelectric layer 21 by bonding, and specifically conductive glue can be used to achieve electrical connection between the first electrode 22 and the second electrode 23 and the piezoelectric layer 21 .

[0046] Furthermore, the first electrode 22, the piezoelectric layer 21, and the second electrode 23 are arranged in a one-to-one correspondence. Specifically, the first electrode 22 and / or the second electrode 23 can be fixed to the vibration motor 3 by gluing, so that the piezoelectric layer 21 can transmit deformation to the vibration motor 3 through the first electrode 22 or the second electrode 23.

[0047] Optionally, the piezoelectric module 2 can be arranged between the vibration motor 3 and the circuit board 11; one end of the piezoelectric module 2 arranged in the first area of ​​the vibration motor 3 can be fixedly connected to the circuit board 11, and the other end arranged in the second area of ​​the vibration motor 3 can be movably connected to the circuit board 11.

[0048] In the embodiment of the present application, the piezoelectric module 2 is positioned between the vibration motor 3 and the circuit board 11, facilitating connection of the first electrode 22 and the second electrode 23 in the piezoelectric module 2 to the circuit board 11, thereby simplifying the structure of the electronic device. Furthermore, the other end of the piezoelectric module 2, positioned in the second region of the vibration motor 3, is movably connected to the circuit board 11, facilitating the piezoelectric module 2 lifting the circumferential edge of the vibration motor 3 and tilting the vibration motor 3 relative to the circuit board 11.

[0049] Specifically, the piezoelectric module 2 is disposed at one end of the first region of the vibration motor 3 as the inner ring, and the piezoelectric module 2 is disposed at the other end of the second region of the vibration motor 3 as the outer ring. The first electrode 22 can be fixedly connected to the vibration motor 3; the inner ring portion of the second electrode 23 can be fixed to the circuit board 11 by gluing, while the outer ring portion can be left unfixed, so that the outer ring of the piezoelectric module 2 can be movably connected to the circuit board 11. Specifically, utilizing the inverse piezoelectric effect, when the first electrode 22 and the second electrode 23 are energized, the outer ring of the piezoelectric layer 21 can bend upward, thereby allowing the circumferential edge of the vibration motor 3 to be lifted by the first electrode 22, causing the vibration motor 3 to tilt relative to the device body 1; when the first electrode 22 and the second electrode 23 are not energized, the vibration motor 3 can be placed parallel to the circuit board 11.

[0050] Optionally, the piezoelectric module 2 may be disposed on a side of the vibration motor 3 away from the circuit board 11 .

[0051] In an embodiment of the present application, the piezoelectric module 2 is arranged on the side of the vibration motor 3 away from the circuit board 11, so that the piezoelectric module 2 pulls the circumferential edge of the vibration motor 3 away from the circuit board 11, causing the vibration motor 3 to tilt relative to the circuit board 11.

[0052] Specifically, the second electrode 23 can be fixedly connected to the vibration motor 3; the inner circle of the second electrode 23 can be fixed in the first area of ​​the vibration motor 3, and the outer circle of the second electrode 23 can be fixed in the second area of ​​the vibration motor 3. In this way, when the first electrode 22 and the second electrode 23 are energized, the piezoelectric layer 21 is deformed, and the circumferential edge of the vibration motor 3 can be pulled upward by the second electrode 23, so that the vibration motor 3 is tilted relative to the circuit board 11.

[0053] Optionally, the circuit board 11 may be a flexible circuit board, and the device body 1 may further include a reinforcing plate 12 ; the reinforcing plate 12 may be fixed to a side of the circuit board 11 close to the piezoelectric module 2 to support the vibration motor 3 and the piezoelectric module 2 .

[0054] In the embodiment of the present application, the circuit board 11 is configured as a flexible circuit board to facilitate wiring on the circuit board 11. A reinforcing plate 12 is provided on the side of the circuit board 11 close to the piezoelectric module 2 to improve the structural strength of the circuit board 11, thereby facilitating the support and installation of the vibration motor 3 and the piezoelectric module 2.

[0055] Specifically, the reinforcing plate 12 can be a stainless steel reinforcing plate, an aluminum foil reinforcing plate, a polyester reinforcing plate, a polyimide reinforcing plate, a glass fiber reinforcing plate, a polytetrafluoroethylene reinforcing plate, a polycarbonate reinforcing plate, etc. In the embodiment of the present application, only the reinforcing plate 12 is used as a reinforcing steel sheet as an example for explanation, and other situations can refer to the settings.

[0056] Optionally, the device body 1 may further include a first elastic member 13 , and the first elastic member 13 may be connected to the vibration motor 3 and the circuit board 11 respectively.

[0057] In the embodiment of the present application, the first elastic member 13 is connected to the vibration motor 3 and the circuit board 11 respectively, so that when the piezoelectric module 2 stops driving the vibration motor 3, the vibration motor 3 can quickly return to its initial position.

[0058] Specifically, if Figure 5 As shown, when the piezoelectric module 2 is powered, the piezoelectric module 2 can drive the vibration motor 3 to tilt relative to the circuit board 11, as shown in FIG. Figure 6 As shown, the piezoelectric module 2 is not powered on, and the piezoelectric module 2 stops driving the vibration motor 3 , so that the vibration motor 3 can return to the initial position under the rebound force of the first elastic member 13 .

[0059] Specifically, the first elastic member 13 can be a spring, a spring, or an elastic conductive member, etc., and can be configured according to actual needs. The embodiment of the present application does not specifically limit this.

[0060] Furthermore, the first elastic member 13 may also be an elastic conductive member. In this way, the first elastic member 13 may be electrically connected to the vibration motor 3 and the circuit board 11 respectively, so that the circuit board 11 can supply power to the vibration motor 3 .

[0061] Optionally, the piezoelectric module 2 can drive the vibration motor 3 to move relative to the device body 1, so that the vibration motor 3 is tilted at a target angle relative to the device body 1; the target angle can range from 0° to 90°.

[0062] In the embodiment of the present application, the target angle is controlled within the range of 0° to 90°, which can further improve the omnidirectionality of the 3D vibration sensation provided by the vibration motor 3 .

[0063] Specifically, the target angle can be 10°, 30°, 45°, 60° or 80°, etc., and can be set according to actual needs. The embodiments of the present application do not make specific limitations on this.

[0064] Alternatively, as Figure 2 As shown, the vibration motor 3 may include: a base 31, a shell 32, a first magnetic member 33, a second magnetic member 34 and a second elastic member 35; the shell 32 may be fixedly connected to the base 31, and enclosed with the base 31 to form a accommodating space for accommodating the first magnetic member 33, the second magnetic member 34 and the second elastic member 35; the second elastic member 35 may be connected to the second magnetic member 34 and the base 31 respectively, for connecting the second magnetic member 34 to the base 31; the first magnetic member 33 may be fixedly connected to the base 31, and arranged around the second magnetic member 34, for driving the second magnetic member 34 to impact the shell 32.

[0065] In the embodiment of the present application, the first magnetic member 33 is fixed on the base 31, and the second magnetic member 34 is fixed on the base 31 through the second elastic member 35. In this way, when a magnetic force is generated between the first magnetic member 33 and the second magnetic member 34, the first magnetic member 33 can drive the second magnetic member 34 to collide with the shell 32, thereby generating vibration.

[0066] Specifically, the housing 32 and the base 31 enclose an accommodating space, so that the accommodating space can effectively protect the first magnetic member 33 , the second magnetic member 34 and the second elastic member 35 , thereby increasing the service life of the vibration motor 3 .

[0067] Specifically, the second elastic member 35 can be a spring or a leaf spring, etc., and can be configured according to actual needs. This embodiment of the present application does not specifically limit this.

[0068] Specifically, a repulsive force or an attractive force may be generated between the first magnetic member 33 and the second magnetic member 34. For example, the first magnetic member 33 is a coil and the second magnetic member 34 is a magnet; or the first magnetic member 33 is a magnet and the second magnetic member 34 is a coil, etc.

[0069] Specifically, the first magnetic part 33 and the base 31 can form the stator part of the vibration motor 3, and the second magnetic part 34 can form the mover part of the vibration motor 3. The stator part and the mover part can be connected by the second elastic part 35. In this way, when the first magnetic part 33 and / or the second magnetic part 34 are energized, the second magnetic part 34 can be repelled or attracted by the first magnetic part 33 and produce an upward or downward position, so that the second magnetic part 34 can hit the shell 32 and generate vibration.

[0070] Optionally, the vibration motor 3 may further include a mass block 36 ; the mass block 36 may be fixedly connected to the second elastic member 35 and the second magnetic member 34 , respectively, and the mass block 36 may be movably connected to the first magnetic member 33 .

[0072] Specifically, the mass block 36 may be a structural component with a certain weight. When the second magnetic component 34 drives the mass block 36 to collide with the housing 32 , the mass block 36 may approach or move away from the first magnetic component 33 .

[0073] Optionally, the vibration motor 3 may further include a magnetic conductive member 37 , and the magnetic conductive member 37 may be disposed on the top and / or bottom of the second magnetic member 34 .

[0074] In the embodiment of the present application, a magnetic conductive member 37 is provided on the top and / or bottom of the second magnetic member 34 to increase the magnetic field strength around the second magnetic member 34 .

[0075] Specifically, the number of the magnetic conductive member 37 can be one, and the one magnetic conductive member 37 can be disposed only on the top of the second magnetic member 34, or only on the bottom of the second magnetic member 34. The number of the magnetic conductive member 37 can also be two, and the two magnetic conductive members 37 can be disposed on the top or bottom of the second magnetic member 34 respectively.

[0077] In the embodiment of the present application, one end of the piezoelectric module 2 is arranged in the first area of ​​the vibration motor, and the other end is arranged in the second area of ​​the vibration motor. Since the second area is arranged around the first area and is close to the circumferential edge of the vibration motor, the piezoelectric module 2 can drive the vibration motor 3 to move relative to the device body 1 when powered, so that the vibration motor 3 is tilted relative to the device body 1, so that the vibration motor 3 can generate vibration components in multiple directions, providing a 3D vibration sensation to the user. In the embodiment of the present application, only one vibration motor 3 needs to be arranged in the electronic device, which can save the internal space of the electronic device and reduce the cost of the electronic device. Moreover, by controlling the tilt of the vibration motor 3 relative to the device body 1, resonance between the vibration motor 3 and the camera motor can also be avoided.
