Voice coil vibration and sound player two-in-one motor with high vibration strength

Abstract

The invention relates to the technical field of motors, and discloses a voice coil vibration and sound player two-in-one motor with high vibration strength. The motor comprises a motor shell; two motor end covers which are sequentially mounted at the two ends of the motor shell and used for sealing openings in the two ends of the motor shell; a coil fixing frame which is embedded in the motor shell; a motor coil which is used for generating an excitation magnetic field after being electrified; a vibration assembly which is embedded in the motor coil; a fixed bracket which is propped against the coil fixing frame and the motor coil; a first elastic sheet which is connected with the coil fixing frame and is used for motor vibration; a second elastic sheet which is fixedly connected with thefixed bracket and is used for vibrating the motor; and a wire which penetrates through one end of the motor end cover, is electrically connected with the motor coil and is used for being electricallyconnected with an external power supply and inputting the power supply. The motor disclosed by the invention is high in electromagnetic efficiency and large in vibration quantity, and the interferenceinfluence degree between the motors and between the motors and an external magnetic field is very small.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a high-vibration strength voice coil vibration and audio player two-in-one electric motor. Background technique [0002] Used in the central control operation panel of self-driving cars, smart home touch panels and massage audio vibrators, etc., motors with vibration or music playback functions are required to realize the touch sensing response feedback function; in the head or eye massage category Products that require high vibration intensity or music effect motors. There are usually two solutions for motors that meet this function: one is to choose a rotary motor with an eccentric swing head, or to use a voice coil motor structure; the rotary motor is used because the motor has a trial life and response delay. The time and vibration stress is relatively low, the efficiency is low, and there will be no shortage of audio player functions; furthermore, a voice coil struc...

Problems solved by technology

[0003] In the prior art, the structural layout characteristics of the voice coil motor with the current structure in the industry are as follows: the mover of the motor is the design center magnet, and the magnetic pole direction of the magnet is consistent with the vibration direction; the outer coil is a spiral tube type, and after the coil is energized, The direction of the excited magnetic field is the axial direction of the helical tube. The more turns of the coil and the thicker the wall thickness of the hollow coil, the greater the forced vibration dynam
