Abstract

The invention provides a motor and an electronic device, and the motor comprises a shell, a first electric vibration part, and a mass block. The shell is internally provided with a containing cavity, the first electric vibration part and the mass block are arranged in the containing cavity, the first end of the first electric vibration part is connected with the shell, and the second end of the first electric vibration part is connected with the mass block. When the voltage is applied to the first electric vibration part, the first electric vibration part drives the mass block to move. According to the structure of the motor, the magnetic steel and a coil are omitted, so that magnetic field interference on the circuits and devices around the motor is avoided, and the working environment of the circuits and the devices around the motor is purified; meanwhile, the motor in the embodiment is simple in structure and is convenient to assemble and automatically produce; and in addition, due to the fact that the occupied space of the motor is small, the requirement for thinning the electronic device can be better met.

Description

technical field [0001] The present application relates to the field of electronic devices, in particular to a motor and electronic equipment. Background technique [0002] In current electronic devices, such as mobile phones, handheld game consoles, or handheld multimedia entertainment devices, micro-vibration motors are generally used to realize vibration feedback. [0003] At present, the realization principle of the mainstream motor is: when the current-carrying conductor passes through the magnetic field, it will be subjected to a force, the force is perpendicular to the direction of the current and the magnetic field, and the magnitude of the force is proportional to the current, the length of the wire, and the magnetic flux density. The motor includes a magnet, a mass and a coil. When the coil receives an alternating current, the coil receives an alternating driving force, thereby generating alternating motion, which drives the mass to vibrate and emits a vibration sou...
