Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, in t...

Abstract

The invention discloses a linear vibration motor. Among them, the linear vibration motor includes a shell, a stator assembly, an oscillator assembly and an electromagnetic damping assembly. The casing has a receiving cavity; the stator assembly is received in the receiving cavity and fixed with the casing; the oscillator assembly is suspended in the receiving cavity and connected with the casing. The stator assembly is adapted to vibrate driven by the stator assembly; the electromagnetic damping assembly is contained in the receiving cavity, and the electromagnetic damping assembly includes matching damping magnets and conductors; wherein, the conductors are fixed to the vibrator assembly, and the damping magnets are fixed on the cavity wall of the receiving cavity and located on the side of the conductor away from the vibrator assembly to damp the vibration of the conductor along with the vibrator assembly. The technical solution of the present invention can shorten the braking time of the vibrator component in the linear vibration motor and provide users with a better tactile experience.

Description

technical field [0001] The invention relates to the technical field of linear vibration motors, in particular to a linear vibration motor. Background technique [0002] With the continuous development of science and technology, more and more consumer electronic products appear in people's lives, such as mobile phones, tablet computers, wearable devices, navigators, etc. These consumer electronic products generally use linear vibration motors to Make feedback, such as mobile phone call reminders, message reminders, navigation reminders, etc. In the related art, after the linear vibration motor is powered off, its vibrator assembly enters a simple harmonic vibration stage, which takes a certain period of time to stop, which greatly affects the user's tactile experience. Contents of the invention [0003] The main purpose of the present invention is to provide a linear vibration motor, which aims at shortening the braking time of the vibrator assembly in the linear vibration...
