Embodiment 1

[0069] Such as figure 1 , figure 2 and image 3 As shown, the present embodiment 1 provides a linear vibration motor, including

[0070] Base 1, set along the horizontal direction;

[0071] The shell 2 is fixed on the base 1 and forms an installation space with the base 1;

[0072] A stator assembly, located in the installation space, has a coil 10 and a circuit board 11;

[0073] The vibration assembly is located in the installation space and is arranged opposite to the stator assembly along the first direction, including a mass block 6 and a magnet 7 installed on the mass block 6 close to the stator assembly;

[0074] an elastic component installed on the base 1 and located in the installation space, for suspending the vibrating component in the installation space;

[0075] The bracket 8 is arranged on the base 1, and is used to support the stator assembly, so that the coil 10 is horizontally opposite to the magnet 7;

[0076] When the coil 10 is energized, the mass 6...

Abstract

The invention discloses a linear vibration motor. The linear vibration motor comprises a base, a shell, a stator assembly and a vibration assembly, wherein the shell is fixed on the base, the shell and the base form an installation space, the stator assembly and the vibration assembly are oppositely arranged in the installation space along a first direction, the stator assembly is provided with a coil and a circuit board, the vibration assembly comprises a mass block and a magnet, the magnet is arranged on the mass block and is near to the stator assembly, the vibration assembly is suspended on an elastic assembly in the installation space for supporting a support of the stator assembly, so that the coil and the magnet are horizontally opposite to each other, an electromagnetic force is generated to drive the mass block to do linear motion along a second direction, and the first direction and the second direction are crossed and are on the horizontal plane. The coil, the circuit board and the mass block are arranged in a separated way, the coil vibration cannot be generated by the vibration of the mass block, thus, the electromagnetic force generated by the coil and the magnet is stable, and the vibration stability of the mass block is improved; and no other parts are arranged on and under the mass block, the thickness of the motor can be the thickness of the mass block, and thus, the thickness of the motor is reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a linear vibration motor. Background technique [0002] With the continuous use of portable electronic products, people's requirements for electronic products are getting higher and higher, making electronic products develop in a lighter and thinner direction, especially for the thickness of vibration motors in electronic products. The vibration performance is more stable while the thickness is thinner. [0003] Chinese patent document CN20250856U discloses a horizontal linear vibration motor, including a housing, an upper cover installed on the top of the housing, and an installation space is formed between the housing and the upper cover; a vibration assembly and a stator assembly are sequentially arranged in the installation space along the vertical direction . Wherein, the mass block in the vibrating assembly is arranged along the horizontal direction, the shrapnel is arrang...
