Vibrator

Abstract

The invention relates to a vibrator which comprises permanent magnets, a coil and a hollow cylinder body, wherein, the permanent magnets are one pair, the two permanent magnets are respectively fixedon two sides of a magnetic conductive sheet, the ends with the same polarity of the two permanent magnets are opposite, the two permanent magnets and the magnetic conductive sheet are positioned in acavity of the cylinder body, a magnetic conductive ring is sheathed at the middle part of the surface of the cylinder body, the coil is divided into two parts and wound on the surface of the cylinderbody which is positioned on two sides of the magnetic conductive ring, a housing is sheathed outside the cylinder body, and two ends of the coil are introduced out of the housing. The vibrator has theadvantages of reasonable structure, sensitive vibration, good vibration effect and long service life, and can be widely applied on products like massage devices, sex toys, mobile phones and the like.

Description

technical field [0001] The invention relates to a vibrator, in particular to an electromagnetic vibrator. Background technique [0002] The basic structure of an existing electromagnetic vibrator is that a vibrating element with a magnet is arranged in a cavity of a hollow part, and a spring is placed between one or both ends of the vibrating element and the hollow part. A coil is wound on the outside. When the coil of this kind of electromagnetic vibrator passes through the alternating current, the vibrating part with the magnet can generate vibration. The disadvantages of the above existing electromagnetic vibrator are: the positioning of the vibrating element is realized by the contact with the spring, the amplitude of the vibrating element will be affected by the spring, and the vibration effect is not ideal; especially when the current passing through the coil is relatively low. When the time is small, the resistance of the spring will hinder the vibrating member more...

The disadvantages of the above existing electromagnetic vibrator are: the positioning of the vibrating element is realized by the contact with the spring, the amplitude of the vibrating element will be affected by the spring, and the vibration effect is not ideal; especially when the current passing through the coil is relatively low. Hours, the resistance of the spring will hinder the vibrating part more obviously
