Thin type flat rectilinear vibration motor

Abstract

The invention provides a thin type flat rectilinear vibration motor which comprises a casing, a cover plate covering the casing and forming mounting space with the casing, and a vibration assembly hung inside the mounting space through being positioned by elastic support pieces positioned on the two opposite side walls of the casing, wherein the vibration assembly comprises a vibration block and permanent magnets mounted on the vibration block, and can perform reciprocating vibration in the direction roughly parallel to the bottom surface of the casing under the action of the magnetic field force; a coil is mounted above the permanent magnets at the specific clearance position away from the permanent magnets inside the mounting space; an insulation support plate is mounted at the upper part of the coil, and is provided with a lug boss protruding out of the mounting space from the side surface; a wiring terminal in plug-in connection with a main board of a user terminal is mounted on the lug boss; a conducting wire is pre-buried inside the insulation support plate; one end of the conducting wire is electrically connected with the leading wire end of the coil, and the other end of the conducting wire is electrically connected with the wiring terminal.

Description

technical field [0001] The invention relates to a vibrating motor, in particular to a thin flat linear vibrating motor used in portable consumer electronic products. Background technique [0002] Currently, mobile consumer electronics products on the market generally use vibration motors as system feedback components, for example, mobile phone call notifications, game console vibration feedback, and so on. Existing vibration motors on the market mainly include cylindrical iron core motors, hollow cup motors and flat motors. The structure of the cylindrical iron core motor and the coreless motor has many disadvantages such as complex mechanism, thick motor, many manufacturing processes, complicated process, large motor noise and poor control accuracy. Nowadays, in order to meet the design requirements of thin, light and portable electronic consumer products, vibration motors are gradually developing in the direction of flat, light and thin.

Problems solved by technology

[0010] For this reason, the technical problem to be solved by the present invention is to overcome the defect that the installation structure of the vibration motor in the prior art causes the coil terminal to be welded with the main board of the user end to cause inconvenient replacement, thereby providing a vibration motor that can be replaced when the vibration motor is damaged. It is not necessary to replace the thin flat linear vibration motor of the user-side motherboard at the same time

[0011] Another technical problem to be solved by the present invention is to overcome the problem of poor universality in manufacturing caused by the elastic arm of the vibrating motor in the prior art, thereby providing a method that is convenient to manufacture according to the needs of the user Thin flat linear vibration motor with high versatility in adjusting vibration amount and control accuracy

[0012] Another technical problem to be solved by the present invention is to overcome the problem of complex design and high vibration noise caused by the movable connection of the elastic support part and the counterweight of the vibrating motor in the prior art, thereby providing a vibration motor with simple design and low noise.
