Embodiment Construction

[0019] The specific embodiments of the present invention will be further specifically described below through specific embodiments in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, it is an exploded view of the vibration motor parts. The casing 1 is a cuboid-shaped cavity with one end open, and the lower bracket 4 is a plate-shaped structure with a mounting part. The open end of the casing 1 and the lower bracket 4 are fixedly connected to form the shape. And form a cavity for accommodating the internal structure, the combined magnetic steel 2 is fixedly installed on the inner wall of the casing 1 opposite to the open end, and the two sides of the mass block 3 are respectively connected to the inner walls on both sides of the casing 1 through a spring piece 5 , the quality block 3 and the spring piece 5 and the spring piece 5 and the casing 1 are connected by welding, the coil 7 is located on the lower side of the quality piece 3, the flexible ...

Abstract

The invention relates to the technical field of vibration motors, in particular to a novel horizontal vibration motor with a damping system, comprising a casing, which is cavity-shaped and has an opening at one end; A low bracket is fixedly connected with that open end of the case to form a cavity for accommodating an internal component; A combined magnetic steel which provides a magnetic field for the drive motor and is fixed on an inner wall of the housing opposite to the open end; A mask block, which improves that vibration feeling of the motor, is locate below the combined magnet steel; Two spring sheets to provide an elastic force between the mass and the housing; Two damping glues corresponding to the spring plates one by one to provide damping for the spring plates; A coil that drives the mass to reciprocate linearly and is fixedly connected with a side of the mass close to the open end of the casing; Flexible circuit board connecting external power supply and coil. The invention has the advantages that the damping glue is adopted to provide damping for the motor, the performance of the damping glue hardly changes at high temperature, the vibration displacement of the motoris stable, and the life of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of vibration motors, in particular to a novel horizontal vibration motor with a damping system. Background technique [0002] Miniature vibration motors are indispensable components of electronic products such as mobile phones, tablet computers, and handheld game consoles, which provide users with tactile feedback. As the competition in the smartphone market intensifies, mobile phone manufacturers pay more and more attention to the user's tactile experience, and the vibration feedback effect of customers on the motor is also getting higher and higher. As a result, linear vibration motors that are different from traditional rotor motors have appeared on the market. Compared with traditional rotor motors, linear motors have great advantages in vibration characteristics, response time, service life, noise, etc., and they can provide a variety of vibration modes, providing users with rich and varied and delicate...
