[0002] With the development of society, consumers' demands for toys have also become more diverse. Currently, toys with vibration feedback effects are highly favored by consumers. Such toys usually achieve the vibration effect through a miniature vibration motor, which generally consists of a motor and an eccentric wheel. When the motor rotates, the center mass point of the eccentric wheel is not on the center of the motor's rotation axis, causing the motor to be in a constantly unbalanced state, and vibration is induced due to inertia.

[0003] However, the structure of the vibration motor has aftershocks during use, that is, there is still a duration of vibration feedback due to inertia after power-off, and it has a large power consumption and serious heat generation, posing a safety hazard.

[0005] It achieves the vibration effect through the principle of magnetic vibration. However, it is suitable for screen feedback, has a small overall vibration amount, and it is difficult to obtain an obvious vibration feedback when used in toys, unable to meet the requirements.

[0028] Next, embodiments of the present invention will be described in detail. To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are some, rather than all, of the embodiments of the present invention.

[0029] Therefore, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0030] The terms used herein are intended to explain the embodiments and are not intended to limit and / or define the present invention.

[0031] For example, expressions indicating relative or absolute configurations such as "in a certain direction", "along a certain direction", "parallel", "orthogonal", "center", "opposite", "front, back, left, and right" not only mean such a configuration in a strict sense, but also mean a state of relative displacement with tolerances or with angles or distances that can achieve the same functional degree.

[0032] Referring to Figures 1-3 , the vibration structure provided by the present invention mainly includes a moving part, a fixed part, and a housing part. The housing accommodates the moving part and the fixed part, thereby realizing the axial movement of the moving part in the housing part and generating vibration.

[0033] The moving part includes a magnet 11, an elastic body 12, and a connecting body 13. The fixed part includes a coil 21. The housing part mainly includes a housing 22 and a limiting body 23. Thus, when the coil 21 is energized, the magnet 11 makes an axial movement relative to the coil 21, the elastic member can undergo elastic deformation, and the magnet 11 drives the elastic body 12 to make an axial movement not exceeding the limiting body 23.

[0034] Referring to Figures 3-4 , the connecting body 13 is arranged between the magnet 11 and the elastic body 12 and is used to connect the magnet 11 and the elastic body 12. An annular groove 111 that does not penetrate the magnet 11 is axially provided at one end of the magnet 11, which is just used to accommodate the coil 21. Thus, the coil 21 is inserted into the groove 111, and the coil 21 is not fixedly connected to the magnet. Thus, the coil 21 is surrounded by the magnet 11 and there is a gap between the coil 21 and the magnet 11, which is convenient for relative movement.

[0035] An insulating layer 112, such as a polytetrafluoroethylene layer, is attached to the surface of the magnet 11 to form a plastic envelope on its surface. Here, the connecting body 13 has magnetism. The connecting body 13 passes through the elastomer 12 and the magnet 11 in sequence and locks the elastomer 12 at the other end of the magnet 11. The connecting body 13 can adopt a screw structure here.

[0036] Refer to Figure 5 , the whole elastomer 12 is supported by elastic pieces, which includes an outer ring 121, an inner ring 122 and elastic strips 123. The outer ring 121 surrounds the outside of the inner ring 122 and extends outside the magnet 11. A plurality of the elastic strips 123 are evenly arranged between the inner ring 122 and the outer ring 121. The connecting body 13 is arranged on the inner ring 122. There are holes on the inner ring for the connecting body to pass through. The elastic strips are distributed in a circular array between the outer ring and the inner ring, and the number is even, such as 4, 6, 8, etc. Generally, the shape of the elastomer is a curved structure to improve the stress effect, such as an S-shaped structure. Of course, it can also be in a W-shaped, L-shaped, etc.

[0037] The housing 22 has an accommodation space 220 for accommodating the moving part and the fixing part. The shape of the accommodation space is the same as that of the magnet. For example, if the magnet is cylindrical, the accommodation space is also cylindrical. The overall shape of the housing can be cylindrical or prismatic. The fixing part is fixedly connected to the housing 22. The limiting body 23 is arranged at the open end of the housing 22, and the elastomer 12 is located between the magnet 11 and the limiting body 23.

[0038] Refer to Figure 2 , there is a first heat dissipation hole 231 at the center position of the limiting body 23. There is a second heat dissipation hole 222 at the center position of the end of the housing 22 connected to the coil 21. The coil 21 is arranged around the outside of the second heat dissipation hole 222. Dust-proof membranes 41 are arranged on both the first heat dissipation hole 231 and the second heat dissipation hole 222. The dust-proof membranes are made of non-woven fabric, which ventilates and prevents dust. And the diameter of the first heat dissipation hole is larger than that of the second heat dissipation hole, which is convenient for the heat dissipation process on the side of the elastomer and is also convenient for dissipating a certain impact sound, achieving a better feedback effect.

[0039] Moreover, a plurality of shock-absorbing blocks 31 are arranged at the end of the housing 22 connected to the coil 21. The shock-absorbing blocks 31 surround the coil 21 and correspond to the magnet 11. The number of shock-absorbing blocks is mainly 3 - 4, and they are evenly surrounded around the coil. The shock-absorbing blocks 31 are made of elastic rubber material, which is used to contact the end face of the magnet during the movement process, and can reduce the impact on the housing and extend the service life.

[0040] Refer to Figure 6 , the housing 22 includes a bottom plate 201 and an outer cover 202. The outer cover 202 is an integral structure, such as a straight cylinder shape. The coil 21 is arranged on the bottom plate 201, and the moving part is arranged inside the outer cover 202.

[0041] Reference Figure 7 ,and Figure 6 The difference is that the outer cover 202 in this example includes a first cover body 2021 and a second cover body 2022 which are coaxially arranged and spliced ​​together. The first cover body 2021 is arranged between the base plate 201 and the second cover body 2022. The height of the second cover body 2022 is greater than the height of the first cover body 2021. The height of the magnet 11 is greater than the height of the first cover body 2021.
