Embodiment 1

[0036] like 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 includes a casing, the casing is composed of an upper casing 1 and a lower casing 8, and two mass blocks 4, 10 are arranged in the casing, The mass blocks 4 and 10 are arranged side by side longitudinally along the X axis, there is a gap between the two mass blocks 4 and 10, the two ends of the mass blocks 4 and 10 are respectively connected with shrapnel 3, and each mass block 4 and 10 relies on the shrapnel connected to itself 3 fixed; the mass blocks 4 and 10 are provided with magnets, and the magnets in one mass block 4 are perpendicular to the magnetic poles of the magnets in the other mass block 10 .

[0037] According to design requirements, the mass blocks 4, 10 can also be arranged side by side longitudinally along the Y axis.

[0038] In the mass blocks 4 and 10 , the magnet in the mass block ...

Embodiment 2

[0054] 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 bi-vibration system. The linear vibrator comprises a housing, and two mass blocks in the housing. The two mass blocks are arranged along the X-axis or Y-axis side by side, a gap exists between the two mass blocks, and the two ends of the mass blocks are respectively connected with springs. Each mass block is fixed by the springs connected with the mass block. Magnets are arranged in the mass blocks, and the magnetic pole facing direction of the magnet in one mass block is vertical to the magnetic pole facing direction of the magnet in the other mass block. Two vibration assemblies can obtain two different vibration frequencies, so that the vibrator has complex vibration effects, and special application requirement can be 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 vibrating component, that is, a mass block, with a structure such as figure 1 As shown, the vibration effect is single, the vibration feedback is low, and the response speed is slow. [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 mount...
