A High Vibration Sensitivity Horizontal Vibration Linear Motor

Abstract

The invention discloses a high vibration-sensing horizontal vibration linear motor. It includes a coil assembly, a vibrator assembly and a casing assembly, the coil assembly includes a left coil assembly and a right coil assembly, the vibrator assembly includes a vibrator and a spring, the vibrator is mounted on the spring, the casing assembly includes an upper casing and a lower casing, the left coil assembly and The right coil group is installed on the inner side of the upper casing and is symmetrical to the left and right. The vibrator assembly is installed at the inner center of the upper casing. The centers of the left coil group, the right coil group and the vibrator are on the same horizontal plane and the axis where the spring is located. They are perpendicular to each other, and the lower casing and the upper casing are sealed and connected. The beneficial effects of the present invention are: according to the principle of resonance, by applying a sinusoidal electromagnetic force of the same frequency to the vibrator assembly with a fixed frequency, the vibrator assembly resonates to generate vibration, and a strong vibration is generated in a very short time. sense.

Description

technical field [0001] The invention relates to the related technical field of vibration motors, in particular to a high-vibration-sensitivity horizontal vibration linear motor. Background technique [0002] Linear vibration motors are the mainstream vibration motors used in mobile phones, tablet computers, wearable devices and other communication terminals, game consoles, toys and other equipment. Because of their fast response speed and high vibration feeling, they are welcomed by major mobile phone manufacturers. However, as the height of mobile phones and other equipment is getting lower and lower, strict requirements are placed on the height of vibration motors. Most motors are required to be within 3.0mm in height, which sets up obstacles for the performance of linear motors. Due to the height of general axial vibration linear motors, it is impossible to simply increase the voltage to increase the vibration sense, so the structure of the motor needs to be improved. C...

[0002] Linear vibration motors are the mainstream vibration motors used in mobile phones, tablet computers, wearable devices and other communication terminals, game consoles, toys and other equipment. Because of their fast response speed and high vibration feeling, they are welcomed by major mobile phone manufacturers. However, as the height of mobile phones and other equipment is getting lower and lower, strict requirements are placed on the height of vibration motors. Most motors are required to be within 3.0mm in height, which sets up obstacles for the performance of linear motors. Generally, due to the height of the axial vibration linear motor, it is impossible to simply increase the voltage to increase the vibration feeling, so it needs to be improved from the structure of the motor.
