Embodiment 1

[0033] see Figure 1-3 , the present invention provides the following technical solutions: an electromagnet type horizontal linear vibration motor, including a casing 1, a support 7 is connected to the bottom of the casing 1, a stator assembly is connected to the top of the support 7, and the stator assembly includes a circuit board 6 and a coil 9, wherein the circuit board 6 is connected above the bracket 7, the circuit board 6 is a flexible circuit board, the circuit board 6 is provided with a coil 9, the coil 9 is electrically connected with the circuit board 6, and the inside of the casing 1 is provided with a vibrator assembly , the vibrator assembly includes a mass block 2, a cavity is provided inside the mass block 2, a magnet 4 is connected to both ends of the cavity, the magnet 4 is a cylindrical structure, the coil 9 is located between the two magnets 4, and the mass The block 2 is connected with the casing 1 through the spring leaf 5 .

[0034] Further, the magneti...

Embodiment 2

[0041] The difference between this embodiment and Embodiment 1 lies in that further, the opposite sides of the connecting arms of the spring piece 5 are respectively connected to gaskets 51 , and a damping foam 52 is connected to one gasket 51 .

[0042] By adopting the above technical solution, the spacer 51 can evenly distribute the stress of the spring sheet 5 when it moves, and at the same time provide a bonding position for the damping foam 52. When the spring sheet 5 is squeezed and closed by the vibrator assembly, the damping foam 52 can be compressed smoothly, which is extremely Greatly shorten the free oscillation time of the spring leaf 5, speed up the motor response time, thereby shortening the stop time of the motor, the damping foam 52 is extremely slightly affected by temperature changes, and provides stable damping for the motor movement, without vibration enhancement at high temperatures. The vibration is weakened at low temperature, so it can well limit the mot...

Abstract

The invention discloses an electromagnet-type horizontal linear vibration motor. The motor comprises a motor shell, and a bracket is connected to the lower portion of the motor shell. A stator assembly is connected above the bracket, and the stator assembly comprises a circuit board and a coil. The circuit board is connected above the bracket, and the coil is arranged on the circuit board; the coil is connected with the circuit board through spot welding, and a vibrator assembly is arranged in the machine shell; the vibrator assembly comprises a mass block, a cavity is formed in the mass block, magnetic steel is connected to the two ends of the interior of the cavity, the coil is located between the two magnetic steel, and the mass block is connected with the motor shell through a spring piece. The invention further discloses an implementation method of the electromagnet-type horizontal linear vibration motor. According to the invention, an iron core, the coil and a yoke form an electromagnet structure, and the electromagnet structure and the circuit board form a circuit; after an alternating current is connected, an alternating magnetic field generated by the electromagnet interacts with magnetic fields generated by the magnetic steels on the two sides to drive the vibrator assembly to vibrate along the X axis, so the driving force of motor vibration is increased.

Description

technical field [0001] The invention belongs to the technical field of vibration motors, and in particular relates to an electromagnet type horizontal linear vibration motor and a realization method thereof. Background technique [0002] Miniature vibration motors are indispensable components of electronic products such as mobile phones, tablet computers, and electronic toys, which provide users with tactile feedback.
