Embodiment 1

[0050] 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.

[0051] In the installation space, a magnetically conductive plate 8, a vibration assembly 4, and a coil 5 are sequentially installed from the bottom surface 14 of the casing 1 toward the direction of the cover plate 2 (the c...

Embodiment 2

[0063] This embodiment is a modification based on Embodiment 1, and its difference from Embodiment 1 is that in this embodiment, the coil 5 is located below the permanent magnet 42 and is at a certain distance from the permanent magnet 42 ; At this time, in order to protect the coil 5, two quality limiting blocks 6 are installed on the lower surface of the vibrating block 41, and the vertical distance between the quality limiting blocks 6 and the bottom surface of the casing 1 is less than The distance between the vibrating mass 41 and the upper surface of the coil 5 .

Abstract

The invention provides an improved thin flat linear vibration motor which comprises a protective device, the protective device is positioned between a vibration module and a cover plate or the vibration module and a bottom surface of the machine housing, so as to prevent the vibration module from striking the coil when moving, the coil is protected and noise is greatly decreased accordingly.

Description

technical field [0001] The invention relates to a vibrating motor, in particular to an improved thin and flat linear vibrating motor for 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 vibra...
