Problems solved by technology

However, during the use of the linear motor, the ferrofluid may be squeezed, deformed, dispersed, or even splashed, thus losing its original function and reducing the stability and reliability of the motor. The magnetic fluid is added into the gap between them, which is inconvenient to operate

Embodiment

[0027] A linear vibrating motor with a limit device, such as Figure 1~5 As shown, it includes a casing 1, and the casing 1 is provided with a mover assembly 2, a stator assembly 3 corresponding to the mover assembly 2, and two limit devices 4, and the mover assembly 2 is located between the two limit devices 4 Between them, two limiting devices 4 are arranged along the vibration direction of the moving subassembly 2, and buffer blocks 41 matching with the moving subassembly 2 are respectively arranged on the two limiting devices 4.

[0028] In the present invention, as figure 2 As shown, the X direction and the Z direction are given, and the X direction and the Z direction are perpendicular to each other. The vibration direction of the mover assembly 2 is the X direction, and the vertical direction is the Z direction. Orientation is used as a reference.

[0029] The working principle of the present invention is that the mover assembly 2 interacts with the stator assembly 3...

Abstract

The invention discloses a linear vibration motor with a limiting device. The linear vibration motor comprises a motor shell; a rotor assembly, a stator assembly corresponding to the rotor assembly andtwo limiting devices are arranged in the motor shell; the rotor assembly is located between the two limiting devices; the two limiting devices are arranged in a vibration direction of the rotor assembly; and the two limiting devices are provided with buffer blocks matched with the rotor assembly. The limiting devices are arranged to replace an existing magnetic fluid mode, so that the productionand processing are facilitated, and the stability, the reliability and the service life of the motor and the operability of a manufacturing process are improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a linear vibration motor with a limiting device. Background technique [0002] With the rapid development of electronic products, especially mobile terminal devices such as mobile phones and tablet computers, these electronic devices basically use vibration generators to prevent noise from electronic devices from disturbing others. The traditional vibration generating device uses a rotor motor based on eccentric rotation, which realizes mechanical vibration through the rotation of the eccentric vibrator. During the rotation of the eccentric vibrator, the commutator and brushes will generate mechanical friction and electric sparks, etc., which will affect The rotational speed of the eccentric vibrator further affects the vibration effect of the device. Therefore, the vibration generating device mostly uses a linear motor with better performance. [0003] Linear motors, also known ...
