[0085] To solve the drawbacks of a single vibration mode and weak vibration feeling of a vibration device, an embodiment of the present invention provides a vibration device that can vibrate in two-axis or three-axis directions and can improve the vibration feeling.

[0086] The vibration device of the embodiment of the present invention can be used in different electronic devices, and can be specifically applied to mobile phones, tablet computers, game consoles, etc.

[0087] The vibration device described in the embodiment of the present invention includes a vibration assembly 20, a first oscillator 30, and a first housing 10. The vibration assembly 20 vibrates along a first axis x and / or a second axis y. The first oscillator 30 vibrates along a third axis z. The first housing 10 has a first cavity for accommodating the first vibration assembly 20 and the first oscillator 30. Wherein, the first axis x, the second axis y, and the third axis z are perpendicular to each other in pairs.

[0088] In the first embodiment of the present invention, a two-axis vibration device is provided that can vibrate along two axes. Wherein, the vibration assembly 20 vibrates along the second axis y. The first oscillator 30 vibrates along the third axis z.

[0089] Figure 1 It is a three-dimensional schematic diagram of the vibration device of the first embodiment of the present invention. Figure 2It is a schematic diagram of the first implementation mode of the vibration device according to the first embodiment of the present invention. As Figure 1 and Figure 2 shown. The vibration device includes a vibration assembly 20, a first oscillator 30, a first housing 10, and a second connecting plate 40.

[0090] The vibration assembly 20 includes a second housing 21 and a second oscillator or a third oscillator inside the second housing 21. The third oscillator vibrates along the second axis y. The second oscillator vibrates along the first axis x. Specifically, the second oscillator and the third oscillator can be a linear oscillator, a piezoelectric sheet, or a cantilever piezoelectric oscillator respectively. In this embodiment, the vibration assembly includes a third oscillator, and the third oscillator is a linear oscillator that vibrates along the second axis y.

[0091] The first oscillator 30 vibrates along the third axis z. The first oscillator 30 can be a piezoelectric sheet or a cantilever piezoelectric oscillator. In this embodiment, the first oscillator 30 is a piezoelectric sheet. The piezoelectric sheet is located between the first housing 10 and the vibration assembly 20, and the piezoelectric sheet is arranged parallel to the bottom surface of the first housing 10. The piezoelectric sheet is a sheet structure made of piezoelectric material. Due to the inverse piezoelectric effect, the piezoelectric sheet will deform according to the magnitude and frequency of the electrical signal, and then vibrate. The first surface of the piezoelectric sheet is fixedly connected to the second housing 21 of the vibration assembly 20. The piezoelectric sheet has the advantages of light weight and small volume, and can reduce the volume of the vibration device.

[0092] The inverse piezoelectric effect refers to the phenomenon that applying an alternating electric field to a crystal causes mechanical deformation of the crystal. The piezoelectric sheet is mainly made of materials such as piezoelectric ceramics, piezoelectric polymers, or composite piezoelectrics. In this embodiment, the piezoelectric sheet is made of piezoelectric ceramics and has the advantages of small volume, light weight, and fast response speed.

[0093] The first housing 10 includes a first upper shell 11 and a first lower shell 12. The first upper shell 11 and the first lower shell 12 are fixedly connected. Specifically, it can be fixedly connected by means such as bonding or clamping. In this embodiment, the size of the first upper shell 11 of the first housing 10 is smaller than the size of the first lower shell 12, and the first upper shell 11 is at least partially located in the first lower shell 12. The dimension of the first upper shell 11 along the second axis y is slightly larger than the dimension of the vibration assembly 20 along the second axis y. At the bottom of the first lower shell 12, there are two second fixing portions 121 protruding inward from the bottom surface of the first lower shell 12. The two first fixing portions 2121 are respectively close to both ends of the bottom surface.

[0094] The vibration device further includes a second connecting plate 40. Both ends of the first surface of the second connecting plate 40 are fixedly connected to the second fixing portion 121, and the second surface of the second connecting plate 40 is fixedly connected to the second surface of the first oscillator 30. The second surface and the first surface of the first oscillator 30 are opposite to each other. The second connecting plate 40 can be a sheet with good elasticity. The material of the second connecting plate 40 can be spring steel, and the thickness can be 0.1 - 1 mm. By fixedly connecting the second connecting plate 40 to the second fixing portion 121, the middle part of the second connecting plate 40 is suspended, and it has elasticity when the oscillator vibrates, can vibrate together with the oscillator, and can improve the vibration intensity. At the same time, since the piezoelectric sheet made of piezoelectric ceramics is relatively brittle, the second connecting plate can protect the piezoelectric sheet.

[0095] At the same time, the vertical distance between the upper surface of the second fixing portion 121 and the upper surface of the first upper shell 11 is basically equal to or slightly greater than the size of the vibration assembly 20, the first oscillator 30, and the second connecting plate 40 along the third axis z. To minimize the size of the vibration device.

[0096] In this embodiment, the second connecting plate 40, the first oscillator 30, and the vibration assembly 20 are fixedly mounted on the second fixing portion 121 in the first housing 10 in a stacked manner from bottom to top. Among them, the vibration assembly 20 vibrates along the second axis y, the first oscillator 30 vibrates along the third axis z perpendicular to the second axis y, and the vibration assembly 20 and the first oscillator 30 are encapsulated in the first housing 10, which can enable the formed vibration device to vibrate along the second axis y and the third axis z simultaneously.

[0097] Figure 3 It is a schematic diagram of the second implementation manner of the vibration device according to the first embodiment of the present invention. As Figure 3 shown, the difference between the second implementation manner and the first implementation manner is that a second bracket 50 is provided between the first oscillator 30 and the vibration assembly 20.

[0098] Figure 4 It is a cross-sectional schematic diagram of the second implementation manner of the vibration device according to the first embodiment of the present invention. As Figure 3 and Figure 4 shown, at least part of it is disposed between the first oscillator 30 and the vibration assembly 20, and is directly or indirectly fixedly connected to the first oscillator 30 in a manner of elastically deforming along the third axis z.

[0099] The second bracket 50 includes a second part 51, and a third inclined surface 52 and a fourth inclined surface 53 extending obliquely upward from both ends of the second part 51.

[0100] The second part 51 is fixedly connected to the first oscillator 30. Specifically, the dimension of the second part 51 along the second axial direction y is smaller than that of the vibration assembly 20, and the dimension of the second part 51 along the first axial direction x is substantially equal to the dimension of the vibration assembly 20 along the first axial direction x. The bottom of the second part 51 is fixedly connected to the first surface of the first oscillator 30. Specifically, bonding or clamping can be used for the fixed connection. The second part 51 is arranged at the middle part of the first surface of the first oscillator 30, and the center line of the second part 51 coincides with the center line of the first surface.

[0101] The third inclined surface 52 is fixedly connected to the first end of the second part 51, and the angle between the third inclined surface 52 and the second part 51 is an obtuse angle. The fourth inclined surface 53 is fixedly connected to the second end of the second part 51, and the angle between the fourth inclined surface 53 and the second part 51 is an obtuse angle. The angle between the third inclined surface 52 and the second part 51 is 120° - 170°.

[0102] The third inclined surface 52 and the fourth inclined surface 53 are symmetrically arranged on both sides of the second part 51, and the third inclined surface 52 and the fourth inclined surface 53 are respectively in contact with two opposite sides of the first side surface of the vibration assembly 20. The distance between the ends of the third inclined surface 52 and the fourth inclined surface 53 is slightly larger than the dimension of the vibration assembly 20 along the second axial direction y. The second part 51, the third inclined surface 52 and the fourth inclined surface 53 are arranged between the first side surface of the vibration assembly 20 and the first oscillator 30.

[0103] In an optional implementation manner, the second bracket 50 surrounds the side surface of the vibration assembly 20. Specifically, the part of the second bracket 50 located outside the second side surface is parallel to the second side surface, the part of the second bracket 50 located outside the third side surface is parallel to the third side surface, and the part of the second bracket 50 located outside the fourth side surface is parallel to the fourth side surface. The first side surface and the second side surface are oppositely arranged, and the third side surface and the fourth side surface are oppositely arranged.

[0104] The second bracket 50 can be formed by bending a steel plate with a width similar to the dimension of the vibration assembly 20 along the third axial direction z.

[0105] In this embodiment, by providing the second bracket 50 surrounding the side of the vibration assembly 20, a third inclined surface and a fourth inclined surface are provided between the first oscillator 30 and the vibration assembly 20. The bottom of the second bracket 50 is fixedly connected to the first oscillator 30. When the first oscillator 30 vibrates, the third inclined surface 52 and the fourth inclined surface 53 of the second bracket 50 undergo elastic deformation, and thus the second bracket 50 is formed into an elastic force to restore its initial state. A third inclined surface and a fourth inclined surface are provided between the first oscillator 30 and the vibration assembly 20. The third inclined surface 52 and the fourth inclined surface 53 vibrate along with the vibration of the first oscillator 30 along the third axis z, and the third inclined surface 52 and the fourth inclined surface 53 cause a greater vibration amplitude. The second bracket 50 surrounding the vibration assembly 20 can prevent the vibration assembly 20 from moving too far in the direction of the second axis y, resulting in the vibration assembly 20 being skewed relative to the third inclined surface 52 and the fourth inclined surface 53 and affecting the vibration effect. Moreover, the second bracket 50 plays a certain buffering role, so that the vibration assembly 20 does not hit the inner wall of the first housing 10, avoiding excessive vibration intensity and causing damage to the vibration device. That is to say, because the third inclined surface 52 and the fourth inclined surface 53 have a certain angle and a small contact area with the piezoelectric sheet, they can play a role similar to a spring and can increase the acceleration and displacement of the system.

[0106] Figure 5 The vibration assembly 20, the second bracket 50, the first oscillator 30, and the second connecting plate 40 are of the second implementation manner of the first embodiment of the present invention. As Figure 5 shown, in another alternative implementation manner, the second bracket 50 may only include a second part, a third inclined surface, and a fourth inclined surface.

[0107] Figure 6 It is a schematic diagram of the third implementation manner of the vibration device of the first embodiment of the present invention. Figure 7 It is a cross-sectional schematic diagram of the third implementation manner of the vibration device of the first embodiment of the present invention. Figure 8 It is a cross-sectional schematic diagram of the third bent plate 60, the first oscillator 30, and the fourth bent plate 70 of the third implementation manner of the vibration device of the first embodiment of the present invention. As Figures 6 - 8 shown, the difference between the third implementation manner and the first implementation manner is that the second connecting plate 40 is not included, and the third bent plate 60 and the fourth bent plate 70 are provided on both sides of the first oscillator 30.

[0108] The third bent plate 60, the first oscillator 30, and the fourth bent plate 70 are fixedly connected in a sequentially stacked manner, and the third bent plate 60 and the fourth bent plate 70 respectively protrude toward both sides of the first oscillator 30. The third bent plate 60 is fixedly connected to the second fixing portion 121, and the fourth bent plate 70 is fixedly connected to the vibration assembly 20.

[0109] The third bent plate 60 and the fourth bent plate 70 are symmetrically arranged on the second surface and the first surface of the first oscillator 30. Specifically, the third bent plate 60 may include a convex portion in the middle and two flat surfaces at both ends of the convex portion. The third bent plate 60 has a structure similar to a bent bow. The upper surfaces of the two flat surfaces are fixedly connected to the first surface of the first oscillator 30. The lower surfaces of the two flat surfaces are fixedly connected to the second fixing portion 121. The upper surface of the convex portion of the fourth bent plate 70 is fixedly connected to the vibration assembly 20. The lower surfaces of the two flat surfaces of the fourth bent plate 70 are fixedly connected to the second surface of the first oscillator 30.

[0110] Utilizing the inverse piezoelectric effect of the piezoelectric sheet, when an electrical signal is applied to the voltage sheet, the piezoelectric sheet drives the piezoelectric sheet to vibrate up and down through its telescopic movement. Specifically, the third bent plate 60 and the fourth bent plate 70 generate concave and convex deformations. Specifically, when the piezoelectric sheet contracts along the second axis y, the third bent plate 60 and the fourth bent plate 70 generate outward convex deformations; when the piezoelectric sheet expands, the third bent plate 60 and the fourth bent plate 70 generate inward concave deformations. After the third bent plate 60 and the fourth bent plate 70 generate outward convex and inward concave deformations, they push the oscillator 20 to vibrate up and down along the third axis z. The piezoelectric sheet drives the fourth bent plate 70 and the vibration assembly 20 to vibrate along the third axis z in sequence. Since the flat surfaces at both ends of the fourth bent plate 70 are fixedly connected to the first oscillator 30, and the convex portion does not contact the first oscillator 30, the amplitude can be increased.

[0111] Figure 9 It is a schematic diagram of the fourth implementation manner of the vibration device according to the first embodiment of the present invention. Figure 10 It is a cross-sectional schematic diagram of the fourth implementation manner of the vibration device according to the first embodiment of the present invention. As Figure 9 shown, the difference between the fourth implementation manner and the third implementation manner is that a second bracket 50 is provided between the fourth bent plate 70 and the vibration assembly 20.

[0112] The second bracket 50 in this implementation manner can refer to the second bracket 50 in the second implementation manner. In this embodiment, the bottom surface of the second part of the second bracket 50 is fixedly connected to the upper surface of the convex portion of the fourth bent plate 70.

[0113] In this embodiment, by simultaneously adopting the second bracket 50 in the second implementation manner and the structures of the third bent plate 60 and the fourth bent plate 70 in the third implementation manner, the acceleration and amplitude of the vibration device can be further improved, thereby improving the performance of the vibration device.

[0114] Figure 11 It is a cross-sectional schematic diagram of the fifth implementation manner of the vibration device according to the first embodiment of the present invention. Figure 12 It is a schematic diagram of the fifth implementation manner of the vibration device according to the first embodiment of the present invention. As Figure 11 and 12As shown, the difference between the fifth implementation and the first implementation is that the piezoelectric sheet in the first implementation is replaced by a cantilever beam oscillator.

[0115] In this implementation, the cantilever beam oscillator includes a cantilever beam and a piezoelectric element. The cantilever beam includes a flexural-tensional sheet 82 and at least two connecting blocks 81 provided at both ends of the flexural-tensional sheet 82. The two connecting blocks 81 are arranged oppositely, and the cantilever beam forms a receiving space. The piezoelectric element 83 is arranged in the receiving space, and both ends of the piezoelectric element 83 are respectively connected to the connecting blocks. After receiving an electrical signal, the piezoelectric element 83 expands and contracts, causing the distance between the connecting blocks 81 to change, thereby causing the flexural-tensional sheet 82 connected to the connecting blocks 81 to bend or stretch, and further causing the cantilever beam oscillator to vibrate.

[0116] The cantilever beam oscillator can play a role in adjusting the compliance of the system, and thus adjust the resonance frequency.

[0117] It should be understood that the cantilever beam oscillator can also have various shape structures, such as trapezoidal or triangular, etc.

[0118] Figure 13 It is a schematic diagram of the sixth implementation of the vibration device according to the first embodiment of the present invention. Figure 14 It is a cross-sectional schematic diagram of the sixth implementation of the vibration device according to the first embodiment of the present invention.
