Embodiment 1

[0036] Such as 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 with the magnetic circuit arranged horizontally includes a casing, the casing is composed of an upper casing 1 and a lower casing 8, and two pieces are arranged in the casing The mass blocks 4 are arranged side by side along the X-axis longitudinally. There is a gap between the two mass blocks 4. The two ends of the mass blocks 4 are respectively connected with shrapnel 3. Each mass block 4 is fixed by the shrapnel 3 connected to itself.

[0037] The mass blocks 4 are provided with magnets, wherein the magnets in one mass block 4 and the magnetic poles of the magnets in the other mass block 4 are arranged oppositely in the horizontal plane, and the coils 6 corresponding to the magnets are arranged in the gap between the two mass blocks 4 .

[0038] Since the coil 6 is to be arranged in the gap, it is...

Embodiment 2

[0053] 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 with horizontally-arranged magnetic paths and dual vibration systems. The linear vibrator comprises a shell, wherein two mass blocks are arranged in the shell; the mass blocks are longitudinally arranged side by side along an X or Y axis; a gap is formed between the two mass blocks; elastic sheets are connected with the two ends of the mass blocks respectively; each mass block is fixed by the corresponding elastic sheet which is connected therewith; the mass blocks are provided with magnets; the magnetic poles of the magnet in one mass block and the magnet in the other mass block are arranged in a horizontal plane oppositely; coils corresponding to the magnets are arranged in the gap between the two mass blocks. According to the linear vibrator, different vibration frequencies can be obtained due to the two vibration assemblies, so that the liner vibrator has a complicated vibration effect and can satisfy special applications.

Description

technical field [0001] The invention relates to a linear vibrator of a double vibrating system with magnetic circuits arranged horizontally, 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] In the existing linear vibrator, the coil is flatly attached to the FPCB of the lower shell, and the magnet and the mass block are located ab...
