Title:
ACCELEROMETER
Document Type and Number:
WIPO Patent Application WO/2024/045256
Kind Code:
A1
Abstract:
An accelerometer, comprising a base, anchors (1) arranged on the base, seesaw structures (2) elastically connected to the anchors (1), and a differential measurement assembly (3) used to measure the acceleration of the seesaw structures (2), wherein each seesaw structure (2) comprises a first seesaw structure (21) and a second seesaw structure (22), which are parallel to each other and are reversely placed; each anchor (1) comprises a first anchor (11) elastically connected to the first seesaw structure (21), and a second anchor (12) elastically connected to the second seesaw structure (22); the first seesaw structure (21) comprises a first elastic member (211) connected to the first anchor (11), and a first mass block (212) connected to the first elastic member (211); the first mass block (212) is driven from the first anchor (11) by means of a forward-phase carrier driving signal; the second seesaw structure (22) comprises a second elastic member (221) connected to the corresponding second anchor (12), and a second mass block (222) connected to the second elastic member (221); and the second mass block (222) is driven from the second anchor (12) by means of a reverse-phase carrier driving signal. The impact of rotational angular acceleration noise can be effectively suppressed.
