Embodiment 1

[0037] see Figure 1-5 , the present invention provides the following technical solutions: a horizontal linear vibration motor, including a casing 1, a lower cover 12 is connected below the casing 1, a stator assembly is connected above the lower cover 12, and a vibrator is arranged above the stator assembly Assemblies, the two sides of the vibrator assembly are connected to the casing 1 through the spring piece 13, the stator assembly includes the coil 8, the iron core 9, the FPC circuit board 10 and the damping plate 11, wherein the damping plate 11, the FPC circuit board 10 and the coil 8 from The coil 8 is electrically connected to the FPC circuit board 10, and the iron core 9 is arranged inside the damping plate 11, the FPC circuit board 10 and the coil 8. The vibrator assembly includes a counterweight 5. The inside of the counterweight 5 is provided with two magnets 6 arranged side by side, and the inside of the counterweight 5 is provided with a cavity for accommodating...

Embodiment 2

[0053] The difference between this embodiment and Embodiment 1 is that further, the two sides of the connecting arm connecting the spring leaf 13 to the casing 1 and the side of the connecting arm connected to the counterweight 5 and away from the counterweight 5 are respectively connected. There is stopper 7.

[0054] By adopting the above-mentioned technical solution, the stopper 7 converts the fixing method from point fixing (welding) to surface fixing (surface bonding), so as to ensure the smooth operation of the spring leaf 13 during work, and also provide space for the deformation of the spring leaf 13.

[0055] Further, the implementation method of the horizontal linear vibration motor according to the present invention includes the following steps:

[0056] (1) The casing 1 and the lower cover 12 form a closed cavity for accommodating the vibrator assembly and the stator assembly inside;

[0057] (2) The vibrator assembly is mainly composed of a counterweight 5, a bal...

Abstract

The invention discloses a horizontal linear vibration motor. The horizontal linear vibration motor comprises a shell, wherein a lower cover plate is connected with the lower portion of the shell; a stator assembly is connected with the upper portion of the lower cover plate; a vibrator assembly is arranged above the stator assembly; the two sides of the vibrator assembly are connected with the shell through spring pieces; the stator assembly comprises a coil, an iron core, an FPC circuit board and a damping plate, the damping plate, the FPC circuit board and the coil are sequentially stacked above the lower cover plate from bottom to top, and the iron core is arranged in the damping plate, the FPC circuit board and the coil in a penetrating mode; and the vibrator assembly comprises a balancing weight, and two pieces of magnetic steel arranged in parallel are arranged in the balancing weight. The invention further discloses an implementation method of the horizontal linear vibration motor. The electromagnetic property of the damping plate causes large eddy current loss generated on the vibrator assembly during movement of the vibrator assembly, so reliable energy consumption is generated for stopping the motor; and the electromagnetic property of the damping plate is slightly changed in a working temperature range, so motor damping is not obviously changed along with the changeof a working environment temperature.

Description

technical field [0001] The invention belongs to the technical field of vibration motors, and in particular relates to a horizontal linear vibration motor and a realization method thereof. Background technique [0002] In recent years, with the continuous expansion of the market for smart consumer electronic devices such as mobile phones, it has driven the continuous upgrading of related industries. Comparisons are made in terms of vision, hearing, camera, touch, etc., in order to gain more market favor. Linear vibrating motors, as premium components for tactile sensation, are playing an increasingly critical role in the competition. However, limited by the cost difference, there are currently more circular Z-axis linear vibration motors on the market, and less rectangular horizontal linear vibration motors. This is mainly because the rectangular horizontal linear vibration motor has a relatively complex structure, high cost and large size. Therefore, a structure suitable f...
