Mems gyroscope and electronic product technical field

An MEMS gyroscope, comprising:

• two first mass blocks (1) and a second mass block (2), the two first mass blocks (1) being located at two opposite sides of the second mass block (2) in a first direction (Y);
• the second mass block having a first symmetry axis parallel to the first direction and a second symmetry axis perpendicular to the first symmetry axis;
• a plurality of coupling parts (3) each comprising a coupling link (31) and two connecting beams (32) connected to two ends of the coupling link (31), wherein the two connecting beams (32) are flexible beams, each of the coupling parts (3) is positioned between the first mass blocks (1) and the second mass block (2) and connects the first mass blocks (1) with the second mass block (2), the connecting beam (32) connected to one end of the coupling link (31) is connected to the first mass blocks (1), and the connecting beam (32) connected to the other end of the coupling link (31) is connected to the second mass block (2);
• a plurality of driving members (4) located on two sides of the second mass block (2) along a second direction (X) perpendicular to the first direction (Y);
• two decoupling members (5) oppositely arranged along the second direction (X);
• and
• a plurality of coupling beams (6);
• wherein
• the first mass blocks (1) and the second mass block (2) are located between the two decoupling members (5), each said decoupling member (5) and each of the two first mass blocks (1) opposite the decoupling member (5) are connected through one of the plurality of the coupling beams (6), and each said decoupling member (5) is connected to respective ones of the plurality of driving members (4) located at the same side.
