Axial movement double-traction vibration motor

Abstract

The invention discloses an axial movement double-traction vibration motor, and belongs to the field of miniature vibration motors. The axial movement double-traction vibration motor comprises a shell, a stator assembly, a rotor assembly and an end cover, wherein the shell is connected with the end cover, the stator assembly is fixed between the shell and the end cover, and the rotor assembly is arranged in the stator assembly and serves as an axial amplitude piece relative to the stator assembly; the stator assembly is composed of a magnetic frame, a coil holder, a coil and a square needle, the square needle is arranged on the coil holder, the coil is wound on the coil holder through the square needle, and the magnetic frame is sleeved outside the coil; and the rotor assembly is composed of a positioning piece, a spring, a fixing block, magnetic conductive plates, magnetic steel and a shaft rod, the two axial ends of the shaft rod are sleeved with the positioning piece, the spring, the fixing block and the magnetic conductive plates respectively, the positioning piece, the spring, the fixing block and the magnetic conductive plates are in mirror image correspondence and are sequentially distributed from outside to inside, and the magnetic steel is arranged on the shaft rod and located between the two magnetic conductive plates. The vibration motor is reasonable in structural design and good in vibration effect, and the problems that a traditional vibration motor is prone to abrasion, friction noise is generated, and the vibration experience effect is poor in the vibration feedback process can be solved.

Description

technical field [0001] The invention belongs to the technical field of miniature vibration motors, and provides an axial movement double traction vibration motor. Background technique [0002] With the development of electronic technology, portable consumer electronic products are becoming more and more popular, such as mobile phones, handheld game consoles, navigation devices or handheld multimedia entertainment equipment, etc., generally use vibration motors for system feedback, such as mobile phone Incoming call prompts, information prompts, navigation prompts, vibration feedback of game consoles, etc. Such a wide range of applications requires high performance and long service life of the vibration motor. [0003] The vibration feedback mode of the traditional vibration motor is through the rotor motor plus the eccentric hammer, that is: when the motor rotates, the rotor drives the eccentric hammer to rotate, and the centrifugal force generated by the rotating eccentric...
