Linear up-down vibration motor comprising shell formed by magnetic field closed circuit

Abstract

The invention relates to a linear up-down vibration motor comprising a shell formed by a magnetic field closed circuit, the motor comprises a magnetic yoke support and a coil, the magnetic yoke support is bonded with an F-PCB, the coil and a spring and also comprises an upward protrude portion of which plane center portion protrudes upwards, the upward protrude portion is bonded with the magnetic yoke support, the coil is arranged in a central cut-through mode and is vertically bonded with the plane of the above F-PCB, and vertical vibration of a vibrating body are generated through action with a magnet. The magnetic force can be improved, the improved magnetic is gathered, so that the vibration force of the vibration motor can be further improved. According to the invention, the manufacturing process management is simple and convenient, and the poor bond of the production can be minimized. In addition, the motor can reduce tremble and noise caused by tremblling during vibration.

Description

technical field [0001] The present invention relates to an up-and-down vibrating motor, and in particular to a magnetic field closed circuit formed by combining a yoke shell and a yoke bracket to prevent vibrating, increase magnetic force and concentrate the increased magnetic force on the central part, thereby improving the vibrating motor. A linear up-and-down vibrating motor with the effect of vibrating force, in particular to a linear up-and-down vibrating motor {Lineartype vibration motor vibratedVerticality} comprising a magnetic field closed circuit forming a casing Background technique [0002] Recently, with the rapid development of wireless communication technology, the development of portable communication equipment has gradually shown a trend of miniaturization and light weight. Components including circuits have become highly integrated and highly functional, requiring improvements in size and shape to improve space efficiency. [0003] However, a lot of resear...

Problems solved by technology

[0004] The initial model of the vibration motor mounted inside the portable communication device is a rotary vibration motor with a stator and a rotor as the basic structure. The above rotary vibration motor fixes the shaft on the bracket of the stator, and makes the rotor rotate through the shaft support to generate vibration. In order to improve the vibration force, the vibration force is improved by increasing the volume of the rotor or increasing the number of rotations, but due to structural problems, there are limitations in miniaturization, and there are many difficulties in generating high vibrations, and it cannot be guaranteed for a certain period of time. life span
