Title:

LINEAR VOICE COIL ELECTRIC MOTOR

Document Type and Number:

WIPO Patent Application WO/2020/135699

Kind Code:

A1

Abstract:

Disclosed is a linear voice coil electric motor device, comprising a linear voice coil electric motor (10) and a reverse retroreflector (20). The linear voice coil electric motor (10) comprises a swing assembly (11), an elastic assembly (12), and an upper magnetic element (13) and a lower magnetic element (14), which are vertically arranged in a manner of being spaced apart. The swing assembly (11) comprises a swing base plate (110) located between the upper magnetic element (13) and the lower magnetic element (14), a coil (111) arranged on the swing base plate (110), and a left connecting rod (112) and a right connecting rod (113) respectively connected to the left and right sides of the swing base plate (110). The elastic assembly (12) comprises a first left elastic piece (120) and a second left elastic piece (121), which are both connected to the left connecting rod (112), and a first right elastic piece (122) and a second right elastic piece (123), which are both connected to the right connecting rod (113). By means of additionally providing a set of elastic pieces, the acceleration and deceleration processes of the voice coil electric motor (10) are sped up, such that during the sampling of terahertz waves by a detection pulse, the obtained terahertz wave signals are more real and accurate.
