Small High Frequency Vibration Device

Abstract

A small high-frequency vibration device, which includes a central shaft, an iron core rotor, an N-pole magnet group, an S-pole magnet group, a first insulating support, a second insulating support, a coil, and an iron core stator. The iron core rotor is sleeved in the center On the rotating shaft, the N-pole magnet group and the S-pole magnet group are respectively provided with two N-pole magnets and S-pole magnets, which are arranged symmetrically on both sides of the iron core rotor along the central axis of the central rotating shaft, and respectively arranged along the center of the central rotating shaft. The axis is symmetrically arranged on the iron core rotor, the first insulating bracket and the second insulating bracket are symmetrically wrapped around the iron core rotor, the coil is wound on the first insulating bracket and the second insulating bracket in an opposite manner, and the iron core stator wraps Covering the insulating support, when the coil is connected to positive and negative square wave power, the N pole magnet group and the S pole magnet group will drive the central shaft to reciprocate under the action of magnetic force, forming high frequency vibration. The small high-frequency vibration device of the present invention can be widely used in sonic toothbrushes, sonic face washers, massagers, sex toys and other articles on the market.

Description

【Technical field】 [0001] The invention relates to a vibration device, in particular to a small high-frequency vibration device with high vibration frequency, stable vibration frequency, low energy consumption, long service life and low noise. 【Background technique】 [0002] As we all know, the traditional vibration motor installs a set of adjustable eccentric blocks at both ends of the iron core rotor shaft, and uses the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block to obtain the exciting force. The vibration frequency range of the vibration motor is large, and the mechanical noise can only be reduced if the excitation force and power are properly matched. Because it uses an eccentric structure, its amplitude is not uniform, its vibration frequency is not stable enough, and it is not easy to miniaturize. 【Content of invention】 [0003] The present invention aims to solve the above problems and provide a small high-frequency vi...
