[0035] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0036] Embodiment:

[0037] Reference Figure 1 and Figure 2The embodiment discloses a multi-direction vibration motor, which comprises a shell 10, a vibrator assembly 20, a permanent magnet 30 and an electromagnet 40.

[0038] Specifically, the shell 10 is in a strip shape, the inside of the shell 10 is in a hollow structure, and a vibration area 11 is formed. The middle part of the vibrator assembly 20 is rotationally arranged in the vibration area 11, the side part of the vibrator assembly 20 is provided with a knocking part 21, the end part of the vibrator assembly 20 is provided with a vibration part, and the side part of the vibrator assembly 20 is further provided with the permanent magnet 30. The electromagnet 40 is arranged at a position close to the permanent magnet 30.

[0039] In the embodiment, the vibrator assembly 20 is arranged in the shell 10, then the permanent magnet 30 is mounted on the vibrator assembly 20, and the electromagnet 40 is matched with the permanent magnet 30 to drive the vibrator assembly 20 to generate a vibration effect.

[0040] In the process of generating the vibration effect by the vibrator assembly 20, the knocking part 21 of the side part of the vibrator assembly 20 generates a vibration effect on the side wall of the shell 10, and the vibration part of the end part of the vibrator assembly 20 generates a vibration effect on the end part of the shell 10.

[0041] Through the technical scheme, the vibrator assembly 20 can generate vibration effects in two directions at the same time in the vibration process, and the problem of single movement mode in the prior art is broken through.

[0042] In one specific embodiment,

[0043] The vibrator assembly 20 comprises a driving piece 22, a movable piece 23 and a reset piece 24. The driving piece 22 is in a strip shape, the middle part of the driving piece 22 is rotationally arranged in the middle part of the vibration area 11, and the length direction of the driving piece 22 is generally the same as the length direction of the shell 10. When the electromagnet 40 is powered, the length direction of the driving piece 22 forms a certain angle with the length direction of the shell 10.

[0044] The side part of the driving piece 22 is provided with the knocking part 21, and the end part of the driving piece 22 is provided with a driving surface 25. The driving surface 25 is an inclined plane relative to the length direction of the driving piece 22.

[0045] The moving part 23 is the vibration part as described above, and is slidingly arranged in the vibration area 11, and the sliding direction of the moving part 23 is consistent with the length direction of the shell 10. The moving part 23 is located at one end of the driving part 22, and the end of the moving part 23 close to the driving part 22 also has an inclined plane, which is the connecting surface and matches the driving surface 25 on the driving part 22.

[0046] The reset part 24 is arranged between the shell 10 and the moving part 23, and has the tendency to drive the moving part 23 to press the driving part 22.

[0047] In the embodiment, when the electromagnet 40 is powered, the same magnetic poles of the ends of the permanent magnet 30 and the electromagnet 40 repel each other, so that the permanent magnet 30 drives the driving part 22 to rotate, so that the knocking part 21 on the driving part 22 knocks the side wall of the shell 10, thereby generating vibration in one direction. At the same time, the driving surface 25 at the end of the driving part 22 matches the connecting surface at the end of the moving part 23, and when the driving part 22 moves, the moving part 23 moves away from the driving part 22, so that the moving part 23 knocks the end of the shell 10, thereby generating vibration in another direction.

[0048] Preferably, the reset part 24 includes two connecting plates 241 and a spring 242, wherein the two connecting plates 241 are respectively arranged at the side of the moving part 23 and the bottom of the vibration area 11, and generally there is a gap between the two connecting plates 241. The spring 242 is arranged between the two connecting plates 241. The spring 242 has a pressing effect on the two connecting plates 241, thereby driving the moving part 23 to press the driving part 22, so that at the moment when the electromagnet 40 is powered off, the spring 242 releases the elastic potential energy, drives the moving part 23 to press the driving part 22, and thereby resets the driving part 22 through the action of the connecting surface and the driving surface 25.

[0049] In another preferred embodiment, a sliding groove is arranged in the middle of the moving part 23, and a limiting part is arranged in the shell 10 and slidingly arranged in the sliding groove. The length direction of the sliding groove is consistent with the length direction of the moving part 23, and the limiting part is in the form of a square block. Through this design, the movement direction of the moving part 23 can be limited.

[0050] In another preferred embodiment, the side wall of the shell 10 is provided with a pressure bearing block 12 capable of contacting the knocking part 21, wherein the pressure bearing block 12 is made of rubber, and a rubber gasket is arranged at the end of the shell 10, so that the moving part 23 contacts the gasket. Through this design, on the one hand, the strength of the structure of the shell 10 is enhanced, and deformation of the shell 10 in long-term use is avoided, and on the other hand, the texture during vibration is improved, and metal collision sound is avoided.

[0051] In another preferred embodiment, the permanent magnets 30 are arranged in a Halbach array, by which design, one side of the permanent magnets 30 has stronger magnetism, while the other side has weaker magnetism.

[0052] In another specific embodiment,

[0053] The two ends of the vibrator assembly 20 are centrally symmetrically distributed with the knocking portions 21, the vibrating portions, the permanent magnets 30 and the electromagnets 40, wherein the driving member 22 is respectively distributed with the knocking portions 21 and the permanent magnets 30 on the two sides of the same end. By this design, the vibrating effect can be greatly improved. In addition, in order to enhance the stability of the moving body 23, the restoring members 24 are symmetrically arranged on the two sides of the moving body 23.

[0054] The above-described embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as the limitation of the patent scope of the present application. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
