[0018] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] The technical solutions disclosed in the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] like Figures 1-6 As shown in the figure, this application discloses an electronic device, including a housing 100, an electro-deformation drive unit 200, a motion base 300, a mass block 400, a power supply module, and a control module.

[0021] The housing 100 serves as the basic component of the electronic device, providing a mounting base for other components within the device. Simultaneously, the housing 100 provides a protective base for these other components, preventing them from being easily damaged. Specifically, the electro-deformation drive unit 200, the motion base 300, and the mass block 400 are all housed within the housing 100, thus protecting these components from impact damage.

[0022] As an intermediate component connecting the housing 100 and the moving base 300, the electro-deformation drive unit 200 is disposed between the housing 100 and the moving base 300. The electro-deformation drive unit 200 and the mass block 400 are located on opposite sides of the moving base 300, and are staggered. The control module is electrically connected to both the power supply module and the electro-deformation drive unit 200. The power supply module provides power to both the control module and the electro-deformation drive unit 200, and simultaneously controls the operation of the electro-deformation drive unit 200. When the electronic device sends a vibration control message, the control module controls the electro-deformation drive unit 200 to operate. Specifically, when a voltage is applied to the electro-deformation drive unit 200, it drives the moving base 300 to move the mass block 400. Specifically, the electrodeformation drive unit 200 is made of an electrodeformation material (such as a piezoelectric material, shape memory alloy, etc.). When a voltage is applied to the electrodeformation drive unit 200, the electrodeformation drive unit 200 can deform, and then drive the motion base 300 to move through its own deformation. The movement of the motion base 300 can drive the mass block 400 to move.

[0023] In this embodiment, the electro-deformation drive unit 200 deforms when energized. The control module controls parameters such as the energizing direction and current of the electro-deformation drive unit 200, thereby controlling the deformation direction and magnitude. This deformation drives the motion base 300, which in turn drives the mass block 400 to reciprocate. In this case, the reciprocating motion of the mass block 400 provides good vibration feedback to the user.

[0024] The electronic device disclosed in this application improves the structure of the electronic device in the prior art by placing an electro-deformation drive unit 200 between the housing 100 and the moving base 300 as an intermediate component connecting the housing 100 and the moving base 300. The electro-deformation drive unit 200 can drive the moving base 300 to move within the housing 100. The electro-deformation drive unit 200 and the mass block 400 are located on opposite sides of the moving base 300, and the electro-deformation drive unit 200 and the mass block 400 are staggered. When the electronic device sends a vibration control message, the electro-deformation drive unit 200 can drive the moving base 300 and move the mass block 400. The control module is electrically connected to the power supply module and the electro-deformation drive unit 200. When a voltage is applied to the electro-deformation drive unit 200, the control module controls the electro-deformation drive unit 200 to work, thereby driving the moving base 300 and moving the mass block 400, thus realizing the vibration function of the electronic device. Therefore, it can be seen that the electro-deformation drive unit 200 of the electronic device disclosed in this application does not need to generate a magnetic field by a coil, thus avoiding electromagnetic interference to other electronic components of the electronic device, thereby solving the problem that vibration motors in current electronic devices will cause electromagnetic interference to other electronic components of the electronic device.

[0025] Meanwhile, the electro-deformation drive unit 200 and the mass block 400 are staggered, which helps to amplify the deformation of the electro-deformation drive unit 200 through the moving base 300, thereby enabling the mass block 400 to move more significantly and improving the vibration effect. Furthermore, the electro-deformation drive unit 200 and the mass block 400 are located on opposite sides of the moving base 300, which helps to avoid the influence of the mass block 400 on the deformation of the electro-deformation drive unit 200.

[0026] In this embodiment, the moving base 300 and the housing 100 are connected in many ways, such as direct connection, hinged connection, or indirect connection via a spring sheet. This embodiment does not impose any specific limitations on these methods. The moving base 300 can be a long strip-shaped structure. The first end of the moving base 300 is rotatably connected to the housing 100. The mass block 400 is disposed at the second end of the moving base 300 away from the first end. The electro-deformation drive unit 200 is disposed between the two ends of the moving base 300.

[0027] In this configuration, by applying a positive or negative current to the electro-deformation drive unit 200, the moving base 300 can be driven to rotate within the housing 100. Furthermore, under the drive of the electro-deformation drive unit 200, the first end of the moving base 300 is the connecting end and will not oscillate, while the second end of the moving base 300 is the moving end. This prevents movement of the first end of the moving base 300, thereby reducing its impact on other electronic components. Simultaneously, the mass block 400 is positioned at the second end. With the first end as the rotating end, the mass block 400 can follow the second end with a more significant movement, thus improving the vibration effect.

[0028] In a further technical solution, the distance between the electro-deformation drive unit 200 and the first end of the moving base 300 is a first distance, and the distance between the electro-deformation drive unit 200 and the second end of the moving base 300 is a second distance, which can be greater than the first distance. When the second distance is greater than the first distance, according to the lever principle, the electro-deformation drive unit 200, after being energized by the power supply module, undergoes a small deformation, which can drive the moving base 300 to drive the mass block 400 to perform a larger amplitude reciprocating motion, thereby producing more significant vibration.

[0029] By energizing the electro-deformation drive unit 200, the motion base 300 can be driven to move the mass block 400 back and forth. Under normal circumstances, the mass block 400 has a certain weight so as to provide better vibration feedback to the user. Specifically, the mass block 400 can be made of a material with a high density, for example, the mass block 400 can be an iron block.

[0030] In this embodiment, the motion base 300 is a first circuit board, and the mass block 400 can be a functional device. The functional device is electrically connected to the first circuit board. The control module and power supply module can be integrated into the first circuit board. The first circuit board can then control the electro-deformation drive unit 200 to operate, driving the motion base 300 to reciprocate the mass block 400. In this case, there is no need to additionally configure the motion base 300 inside the electronic device; the existing first circuit board of the electronic device can be used as the motion base 300, thereby further reducing the number of components in the electronic device.

[0031] As mentioned above, the mass block 400 can be a functional device, meaning it can be an electrical component or power supply component for the electronic device. In this case, the electronic device can utilize its existing components as the mass block 400 for vibration, without needing to configure additional specialized components as the mass block 400. Clearly, this structure allows the electrical component or power supply component of the electronic device to achieve multiple functions, thereby reducing the number of components and making the electronic device lighter and more portable.

[0032] There are many types of electrical components or power supply devices within electronic devices, and this application embodiment does not limit this. For example, the electrical component can be a camera. In a further technical solution, the mass block 400 can be a battery. The battery can power the electro-deformation drive unit 200, thereby driving the motion base 300 to move the mass block 400 in reciprocating motion. To improve the battery life of electronic devices, electronic devices are usually equipped with a large battery. In this case, the battery has a large mass, resulting in greater inertia during reciprocating motion, which is beneficial for improving vibration performance.

[0033] In this embodiment, the electronic device may further include a second circuit board, which is fixed within the housing 100. The second circuit board and the first circuit board are electrically connected via a first flexible electrical connector (e.g., a flexible circuit board or flexible cable). The second circuit board is also electrically connected to a power supply module. In this case, the power supply module supplies power to the second circuit board. Furthermore, the first flexible electrical connector ensures that the movement of the first circuit board is not affected by the second circuit board when the first and second circuit boards are electrically connected.

[0034] When the mass block 400 is a functional device, it is electrically connected to the first circuit board. In this case, the electronic device can form an oscillator using the existing first circuit board and functional device, and achieve vibration under the drive of the electro-deformation drive unit 200.

[0035] As described above, the electronic device disclosed in this application may include a first circuit board and a second circuit board. The first circuit board and the second circuit board are not limited to being connected by a first flexible electrical connector. Alternatively, the second circuit board and the first circuit board may be an integral structure, with the second circuit board fixed within the housing 100. One end of the first circuit board is connected to the second circuit board, and the other end of the first circuit board is an elastic free end. A mass block 400 is disposed at the elastic free end. In this case, the first circuit board and the second circuit board form a larger area elastic circuit board structure.

[0036] As described above, the electro-deformation drive unit 200 is powered by the power supply module, and the control module can control the electro-deformation drive unit 200 to work, driving the motion base 300 to drive the mass block 400 to reciprocate. In one optional scheme, the electro-deformation drive unit 200 can be a sheet-like structure. Specifically, this sheet-like structure can be a composite material actuator. By applying voltage, the sheet-like structure is deformed, thereby driving the motion base 300 to drive the mass block 400 to reciprocate.

[0037] The electronic device disclosed in this application embodiment may further include a carrier plate 500, and the electro-deformation driving unit 200 may be disposed on the carrier plate 500. The carrier plate 500 is fixedly connected to the housing 100. In one optional embodiment, the carrier plate 500 is connected to a second flexible electrical connector 510. The second flexible electrical connector 510 may be a flexible circuit board or other flexible connectors, such as flexible cables. This application embodiment does not impose specific limitations on this. By fixing the carrier plate 500 to the housing 100, the electro-deformation driving unit 200 can be stably connected to the housing 100, which is beneficial to the stability of the electronic device structure. At the same time, the second flexible electrical connector 510 can play the role of electrical connection, and thus the carrier plate 500 can supply power to the electro-deformation driving unit 200.

[0038] In a further technical solution, the electro-deformation drive unit 200 can be one or two, and this application embodiment does not impose a specific limitation on this. In one optional solution, there can be two electro-deformation drive units 200, respectively disposed on two opposite surfaces of the support plate 500. By energizing the electro-deformation drive units 200, the two electro-deformation drive units 200 can apply a force to the moving base 300 through deformation, thereby driving the movement of the moving base 300 to be more significant, which is beneficial for driving the mass block 400 to vibrate more significantly. Of course, it should be noted that the two electro-deformation drive units 200 should play a synergistic role during the deformation process.

[0039] Furthermore, there are many types of electro-deformation drive units 200, which can be one of piezoelectric material structural parts, ion vibration structural parts or shape memory alloy parts, or other material structural parts. This application embodiment does not make specific limitations on this.

[0040] As described above, the support plate 500 is fixedly connected to the housing 100, and the support plate 500 is used to place the electro-deformation drive unit 200. Specifically, the support plate 500 can be a conductive structural component, which is electrically connected to the second flexible electrical connector 510 through the conductive structural component, thereby achieving the purpose of supplying power to the electro-deformation drive unit 200.

[0041] In this embodiment, the electro-deformation driving unit 200 can be an ion-conducting driving sheet. The ion-conducting driving sheet includes an ion exchange resin layer and a first electrode layer and a second electrode layer respectively disposed on two opposite surfaces of the ion exchange resin layer. The ion exchange resin layer contains a polymer electrolyte. During operation, when the first electrode layer and the second electrode layer are energized, the ion exchange resin layer deforms under the electric field formed by the first electrode layer and the second electrode layer, thereby causing the entire ion-conducting driving sheet to deform.

[0042] In one alternative embodiment, when the voltage applied to the ion-conducting drive plate is a first voltage, the ion-conducting drive plate drives the moving base 300 to move the mass block 400 along a first direction. When the voltage applied to the ion-conducting drive plate is a second voltage, the ion-conducting drive plate drives the moving base 300 to move the mass block 400 along a second direction. The first and second voltages have opposite polarities, and the first and second directions are opposite to each other.

[0043] The control module can control the voltage of the ion-conducting drive plate to switch between a first voltage and a second voltage, thereby enabling the ion-conducting drive plate to reciprocate between a first direction and a second direction. This, in turn, drives the moving base 300 and the mass block 400 to reciprocate between the first and second directions. Specifically, the control module is typically the central processing unit of an electronic device.

[0044] In the specific working process, when the power supply module does not energize the electro-deformation drive unit 200, the electro-deformation drive unit 200 does not deform, such as... Figure 4 As shown. When the power supply module applies a positive voltage (i.e., a first voltage) to the electro-deformation drive unit 200, the electro-deformation drive unit 200 undergoes bending deformation and simultaneously bends outward, as shown. Figure 5 As shown, a force can be applied to the moving base 300, thereby causing the mass block 400 to move in the first direction. When the power supply module supplies a negative voltage (i.e., a second voltage) to the electro-deformation drive unit 200, the bent electro-deformation drive unit 200 returns to its original state, as shown. Figure 6 As shown. By repeatedly supplying power to the electro-deformation drive unit 200, the electro-deformation drive unit 200 deforms repeatedly, thereby driving the motion base 300 to move, which in turn causes the mass block 400 to vibrate.

[0045] In another alternative technical solution, when the voltage applied to the ion-conducting driving plate is a first voltage, the ion-conducting driving plate drives the moving base 300 to move the mass block 400 a first distance along the first direction. When the voltage applied to the ion-conducting driving plate is a third voltage, the ion-conducting driving plate drives the moving base 300 to move the mass block 400 a second distance along the first direction. The first voltage and the third voltage have the same polarity, and the third voltage is greater than the first voltage; the first distance and the second distance are different.

[0046] In other words, by applying voltages of different magnitudes with the same polarity to the ion-conducting drive plate, the ion-conducting drive plate drives the moving base 300 to move the mass block 400 to different degrees, thereby adjusting the amplitude of the vibration and ultimately adjusting the significance of the vibration.

[0047] In another alternative technical solution, when the voltage applied to the ion-conducting driving plate is a first voltage, the ion-conducting driving plate drives the moving base 300 to move the mass block 400 along a first direction at a first rate. When the voltage applied to the ion-conducting driving plate is a third voltage, the ion-conducting driving plate drives the moving base 300 to move the mass block 400 along the first direction at a second rate. The first and third voltages have the same polarity, and the third voltage is greater than the first voltage; the first rate and the second rate are different. The control module can control the voltage of the ion-conducting driving plate to switch between the first and third voltages, thereby driving the moving base 300 to reciprocate at different rates, thus adjusting the vibration frequency.

[0048] In the electronic device disclosed in this application, the moving base 300 is connected to the housing 100 via an elastic structural member 600. Optionally, the elastic structural member 600 can be a spring or other components; this application does not impose specific limitations on this. During operation, one end of the elastic structural member 600 is connected to the moving base 300, and the other end is fixed to the housing 100. Through the elastic contact between the elastic structural member 600 and the electro-deformation drive unit 200, the moving base 300 can move stably when the power supply module energizes the electro-deformation drive unit 200, thus facilitating the reciprocating motion of the mass block 400.

[0049] In one optional embodiment, the two ends of the elastic structural member 600 are connected to the housing 100 and the moving base 300, respectively. During the movement of the mass block 400 driven by the moving base 300, the elastic structural member 600 can extend and retract, acting as a buffer to prevent excessive movement of the mass block 400 and collisions with other components within the electronic device. Specifically, the elastic structural member 600 and the mass block 400 can be located on the same side of the moving base 300; alternatively, the elastic structural member 600 and the mass block 400 can be located on opposite sides of the moving base 300.

[0050] There can be various types of elastic structural components 600, such as springs, elastic rubber pillars, etc. Please refer to [reference needed]. Figure 2 In one optional embodiment, the elastic structural member 600 can be an L-shaped structure. The first right-angled side of the L-shaped structure is fixedly connected to the housing 100, and the second right-angled side of the L-shaped structure is connected to the surface of the back-facing electro-deformation drive part 200 of the moving base 300. During the movement of the moving base 300, the second right-angled side will elastically deform relative to the first right-angled side. This type of elastic structural member 600 not only serves to connect the housing 100 and the moving base 300, but also provides elastic constraint on the moving base 300, thereby indirectly constraining the movement of the mass block 400. This ensures that vibration can occur without excessive vibration that could cause collisions with other components of the electronic device.

[0051] The electronic devices disclosed in this application can be mobile phones, tablets, e-book readers, wearable devices (such as smartwatches), etc. This application does not limit the specific types of electronic devices.

[0052] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0053] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
