Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that, if directional indication is involved in the embodiment of the present invention, the directional indication is only used for explaining the relative positional relationship, the motion situation, and the like between the components in a certain posture, and if the certain posture is changed, the directional indication is changed accordingly.

In addition, if there is a description of "first", "second", etc. in an embodiment of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

Portable consumer electronic products, such as mobile phones, wearable devices, game machines, etc., largely adopt vibration motors as feedback of the system, and with the development of miniaturization and light weight of the consumer electronic products, various components inside the vibration motors need to be adjusted accordingly. The spring plate is used as a supporting element in the linear vibration motor to transmit the vibration of the mass body, and the manufacturing process, the strength and the service life of the spring plate seriously restrict the use of the linear vibrator. In order to avoid the contact between the mechanical elastic sheet and the upper and lower shells in the operation process of the conventional mechanical elastic sheet used in the linear vibrator, an avoiding space for vertical vibration needs to be reserved on the mass block, so that the mass block has small mass and low performance; when the elastic sheet is welded in a laser mode, the energy is large and easy to deform, the flatness is sensitive, the forming is difficult, and when the elastic sheet is not bent in place, the rear leg is easy to tilt, so that the noise of the shell is caused. In addition, the deformation causes frictional heat generation inside the structure of the spring material, which consumes energy, deteriorates the life of the spring, and generates noise. Meanwhile, the elastic sheet is a stressed part, and after the elastic sheet is subjected to the action of alternating stress for a period of time, the elastic sheet can deform and even break, and the service life of the elastic sheet can directly influence the service life of the vibration motor.

In view of this, the present invention provides a vibration device, which utilizes the magnetic levitation principle to generate non-contact bidirectional vibration restoring forces with different frequencies, and utilizes the electromagnetic induction principle to generate two motor thrusts in orthogonal directions, so as to ensure continuous vibration of the vibration device in two directions, thereby effectively prolonging the service life of the vibration device.
