Vibration device and electronic equipment

Abstract

The invention discloses a vibration device and electronic equipment. The vibration device comprises a shell, a magnetic circuit assembly, a coil assembly and an elastic supporting piece, wherein at least part of the magnet of the magnetic circuit assembly or the coil assembly is arranged to be a vibration piece, the elastic supporting piece is connected with the shell and the vibration piece, themagnetizing direction of the magnet of the magnetic circuit assembly is inclined relative to a first direction so as to make each of the first direction and a second direction have a component, the inclination angle between the magnetizing direction and the first direction is alpha; alpha is greater than or equal to 5 degrees and less than or equal to 85 degrees, a coil is provided with a conducting wire section extending along a third direction, at least the conducting wire section of the coil is arranged in the magnetic gap, and the third direction is orthogonal to the first direction and the second direction, so that when the coil is electrified with alternating current, a vibrator vibrates in the first direction and the second direction. According to the invention, the problem that inthe prior art, when vibration in two directions is needed, a plurality of vibration devices are correspondingly needed is solved.

Description

technical field [0001] The invention relates to the technical field of vibration devices, in particular to a vibration device and electronic equipment. Background technique [0002] In electronic devices such as portable information terminals and game machines, vibration devices that generate vibrations such as vibrations for notification of incoming calls in portable information terminals and vibrations for tactile feedback in game machines are used. In the prior art, the vibrating device generally only includes one resonant frequency. If the vibrating device needs to work at two different resonant frequencies, two vibrating devices need to be installed, which is not conducive to the miniaturization development requirements of the vibrating device. Contents of the invention [0003] To this end, the inventor designed a magnetic force with two direction components provided by oblique magnetization, through which the vibrating member movable in the two directions is driven ...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to propose a vibrating device and electronic equipment, aiming to realize vibration in two directions through one vibrating device, so as to solve the problem of requiring multiple vibrating devices when vibrating in two directions is required in the prior art. problem, and by reasonably setting the magnetization direction, so that the distribution of the magnetic field components in the first direction and the second direction is appropriate
