Title:
LINEAR VIBRATION MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/020450
Kind Code:
A1
Abstract:
A linear vibration motor (100), the linear vibration motor (100) comprising a housing (10), a stator assembly (20), a vibrator assembly (30) and a magnetic conductive block (40); the housing (10) is provided with an accommodating cavity (10a); the stator assembly (20) comprises an iron core (22) and a coil (21) wound around the iron core (22), the coil (21) and the iron core (22) being accommodated in the accommodating cavity (10a) and fixed to the housing (10); the vibrator assembly (30) is suspended in the accommodating cavity (10a) by means of an elastic piece; the vibrator assembly (30) is provided with a magnetic piece (31), and the magnetic piece (31) is accommodated in the accommodating cavity (10a) and is arranged opposite to the coil (21) so as to drive, under the drive of the coil (21), the vibrator assembly (30) to vibrate; the magnetic conductive block (40) is accommodated in the accommodating cavity (10a) and magnetically cooperates with the magnetic piece (31), and the magnetic conductive block (40) and the iron core (22) are oppositely arranged on two sides of the vibrator assembly (30). The magnetic conductive block (40) and the iron core (22) are oppositely arranged on two sides of the vibrator assembly (30) to improve the stability of the vibrator assembly (30) of the linear vibration motor (100) during vibration, so as to ensure the reliability and service life of the linear vibration motor (100).
