  • Patent number: 11838737
    Abstract: The present invention provides a vibration motor including a housing with an accommodation space, a vibration member and a fixed member accommodated in the accommodation space, and an elastic support member suspending the vibration member. The elastic support member has an elastic arm, a first fixed part, and a second fixed part. Both the first fixed part and the second fixed part are bent toward the same side of the elastic arm, and the vibration member is located between the first fixed part and the second fixed part. The elastic stress of the elastic support member is effectively improved and the service life of the elastic support member is improved.

  • Patent number: 11674804
    Abstract: The present invention provides a MEMS gyroscope having internal coupling beam, an external coupling beam, a drive structure and a detection structure. The drive structure includes multiple driving weights, and the detection structure includes multiple testing weights. The drive structure further includes a first decoupling structure and a first transducer. The first decoupling structure is arranged on the side of the driving weight far away from the internal coupling beam, and the first transducer excites the driving weight to vibrate. The MEMS gyroscope of the present invention can fully increase the layout area of the first transducer, thereby realizing a larger vibration amplitude under a small driving voltage, thereby increasing the sensitivity.

  • Patent number: 11662206
    Abstract: The present invention provides a micromachined gyroscope, including: a base; an anchor point fixed to the base; a number of vibration structures; and a drive structure used for driving the vibration structure to vibrate in a x-y plane along a ring direction. The drive structure includes at least four groups arranged at intervals along the ring direction and symmetrical about an x axis and a y axis. The micromachined gyroscope works in two vibration modes interchanging with each other, including a driving mode status working in a first mode status and a testing mode status working in a second mode status. By virtue of the configuration described in the invention, the micromachined gyroscope can realize three-axis detection at the same time, and greatly improves the quality utilization rate of the vibration structure.

  • Patent number: 11585659
    Abstract: The present invention is to provide a MEMS wave gyroscope with improved sensitivity. The MEMS wave gyroscope includes a base; an anchor structure fixed to the base; and a volatility structure suspended above the base. The volatility structure includes N horizontal beams and M straight beams for being interlaced to form M nodes. The horizontal beam is divided into M?1 first beam units by the nodes. The straight beam is divided into N?1 second beam units by the nodes. A first in-surface transducer is formed by the second beam unit coupled with a mechanical field and an electric field of the second beam unit on two opposite sides along the second axis. A first out-surface transducer is formed by at least one of two opposite sides of the second beam coupled with the mechanical field and electric field of the second beam unit.
