Embodiment 1

[0031] Such as figure 1 , figure 2 , image 3 , Figure 4 Shown is one of the embodiments of the present invention, in this embodiment, the linear vibrator of the double vibration system comprises a shell, and the shell is composed of an upper shell 1 and a lower shell 8, and two mass blocks 5 are arranged in the shell, and the mass block 5 are arranged side by side longitudinally along the X-axis, there is a gap between the two mass blocks 5, elastic pieces 4 are connected to both ends of the mass blocks 5, and each mass block 5 is fixed by the elastic pieces 4 connected to itself.

[0032] According to design requirements, the mass blocks 5 can also be arranged side by side longitudinally along the Y axis.

[0033] In order to make the linear vibrator have complex vibration effects, in this embodiment, the vibration frequencies of the masses 5 are different.

[0034] In order to realize different vibration frequencies, such a design can be adopted: the mass of the mass ...

Embodiment 2

[0043] In this embodiment, the vibration frequencies of the masses can also be designed to be the same. Correspondingly, the mass of the masses needs to be equal, and the thickness and shape of the shrapnel must be the same.

Abstract

The invention discloses a linear vibrator of a dual-vibration system. The linear vibrator comprises a housing, the housing is internally provided with two mass blocks, the mass blocks are longitudinally arranged side by side along an X axis or a Y axis, a gap exists between the two mass blocks, the two ends of each mass block are connected with springs, and each mass block is fixed by reliance on the springs connected therewith. According to the invention, through two vibration assemblies, different vibration frequencies can be obtained, the linear vibrator is enabled to have a complex vibration effect, and special application is satisfied.

Description

technical field [0001] The invention relates to a linear vibrator of a double vibration system, in particular to a micro motor provided with a double vibrator. Background technique [0002] Linear vibrators are mainly used in mobile phones, tablets, game consoles and smart wearable devices. The vibration direction is along the X-axis, Y-axis or Z-axis. In order to meet the needs of thin and portable electronic consumer products, linear vibrators are required to be thin, flat, It has the characteristics of high vibration feeling and fast response. [0003] The existing linear vibrator mainly includes a vibration component, that is, a mass block, which has a single vibration effect, low vibration feedback, and slow response speed. [0004] For example, the Chinese utility model patent "A Linear Vibration Motor" (CN205178821U) discloses an X-axis vibration motor. A mass block is arranged in the housing, and two magnet mounting holes are arranged in the mass block. Each magnet ...
