Problems solved by technology

[0011] For this reason, the first technical problem to be solved by the present invention is to overcome the defect of low service life of vibration motor coils in the prior art, thereby providing an improved thin flat linear vibration motor with relatively high coil service life
[0012] The second 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
[0013] The third 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 user's end. Thin and flat linear vibration motor with high universality that requires adjustment of vibration amount and control accuracy

Embodiment Construction

[0052] such as 1 and figure 2 As shown, this embodiment provides a vibration motor, including a casing 1 and a cover plate 2 mounted on the casing 1, the casing 1 has a bottom surface 14, and a first side wall 12 connected to the bottom surface 14 , the second side wall 13, the front wall 16 and the rear wall 15, the bottom surface 14 and the above-mentioned side wall of the casing 1 enclose a cavity with a specific height, and the front wall 16 is provided with a concave installation groove 11 , the cover plate 2 has an outwardly protruding cover plate protrusion 21, and the cover plate protrusion 21 is inserted into the concave installation groove 11, so as to connect the cover plate 2 and the casing 1 Composed together to form an installation space.

[0053] In the installation space, a vibrating assembly 4 and two coils 5 connected in series are installed sequentially from the bottom surface 14 of the casing 1 towards the direction of the cover plate 2 (the coil 5 is con...

Abstract

The invention provides a thin type flat linear vibration motor. A protection device is positioned in a machine shell, at least one part of the protection device is arranged opposite to at least one part of an elastic support part in the height direction of the machine shell; the shortest distance from the protection device to the elastic support part is less than the shortest distance from a coil to a vibration block. According to the invention, a vibration assembly can drive the elastic support part to take stretching and compressing movement when vibrating, the elastic support part and the vibration block generate a little vibration in the height direction of the machine shell in the process, because the protection device is arranged, the elastic support part can not directly impact a cover plate, and the vibration block can not directly impact the coil, so that the cover plate and the coil are protected, the integral service life of the vibration motor is prolonged, and the noise is reduced.

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. [0003] A linear vibration motor...
