The invention relates to the technical field of motors. The invention discloses a voice coil vibration motor. The motor comprises a base, a clamping table is arranged on the base, the clamping table is sleeved with a coil; a vibration assembly used for providing a vibration source is arranged on the base, the vibration assembly wraps the coil, a first permanent magnet and a second permanent magnetare sequentially arranged on the outer side of the coil, a first cover plate and a second cover plate which are used for fastening the vibration assembly are arranged on the base, a connecting wire used for being connected with an external signal is further arranged on the base, and the connecting wire is electrically connected with the coil. Through the fastening function of the first cover plate and the second cover plate, the vibration assembly is stably fixed on the base; after the coil is powered on, electromagnetic force is generated for the first permanent magnet and the second permanent magnet, the vibration assembly is used for providing a vibration source, the vibration assembly generates periodic vibration due to the up-down reciprocating periodic electromagnetic force drivingeffect, then the electromagnetic efficiency is improved, the vibration quantity of the voice coil vibration motor is increased, and the appearance size of the voice coil vibration motor is small.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a voice coil vibration motor. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. The main function of the motor is to generate driving torque as a power source for electrical appliances or various machines, and to convert electrical energy into mechanical energy. [0003] In the prior art, when used in the central control operation panel of self-driving cars or smart home touch panels, motors with vibration function are required to realize the touch response feedback function. There are two commonly used schemes, one is to choose a rotary motor plus an eccentric swing head; the other is to use a voice coil vibration motor. When using a rotary motor, the motor has shortcomings such as service life and response delay; while using a voice coil motor, the product efficienc...
