Patent number: 11632620Abstract: A headphone and an electronic device are provided. The headphone includes a gyroscope, which senses a bone conduction vibration and provides a quadrature error signal for reflecting the bone conduction vibration. Specifically, the headphone includes a transmission assembly that acts directly or indirectly on the gyroscope or an inertial measurement unit (IMU) including the gyroscope. The transmission assembly transmits the bone conduction vibration to the gyroscope to make the gyroscope strain, thereby causing the quadrature error signal of the gyroscope to change to detect the bone conduction vibration with sensitivity.Type: GrantFiled: February 25, 2021Date of Patent: April 18, 2023Assignee: SENODIA TECHNOLOGIES (SHAOXING) CO., LTD.Inventors: Bo Zou, Yan Huang, Shuang Liu

Patent number: 11085767Abstract: A three-axis micro electro mechanical system (MEMS) gyroscope includes a central anchor, a first subsidiary proof mass, a first decoupling structure, a second subsidiary proof mass and a third subsidiary proof mass arranged in order from the inside out. When the first subsidiary proof mass resonates in a driving mode around a third direction, the first subsidiary proof mass approximately moves along the first direction. When the first subsidiary proof mass is subjected to an angular velocity around a second direction, a Coriolis force is generated along the third direction, and the first subsidiary proof mass produces a displacement around the first direction under the effect of the Coriolis force. The axis of the first decoupling structure is also in the first direction.Type: GrantFiled: July 18, 2018Date of Patent: August 10, 2021Assignee: SENODIA TECHNOLOGIES (SHAOXING) CO., LTDInventors: Bo Zou, Meihan Guo
