摘要： A rotary actuator with a moving frame includes an electrical coil that moves on an angular travel about an axis of rotation A, the shape of the coil being an elliptical cylinder and the axis of winding B being orthogonal to the axis of rotation A, the coil being placed in the magnetic field of a fixed magnet. The fixed magnet surrounds the coil and includes two semicylindrical portions, the generatrices of which are orthogonal to the axis of rotation A, the first of the semicylindrical portions having a north pole directed toward the coil, orthogonally to the direction of the generatrices and being positioned outside the coil, the second having a south pole directed toward the coil, orthogonally to the direction of the generatrices and also being positioned outside the coil opposite the first portion. The actuator includes a ferromagnetic core inside the coil and an outer ferromagnetic yoke surrounding the fixed magnet, the coil moving in the air gap formed between the magnetized semicylindrical portions and the inner core.

摘要： Aspects of the subject technology relate to a shaker module for an electronic device. The shaker module may include a movable component that is resiliently suspended in relation to a voice coil by one or more gap-separated pairs of the flat springs. The flat springs reduce the z-height of the shaker module for implementation in, for example, compact electronic devices. The gap-separated pairs of flat springs facilitate adjustment of the resonance frequency of the shaker module substantially independently of adjustments to drop performance, while providing stability against unwanted rocking motions of the movable component.

摘要： A linear vibration motor, comprising a stator assembly and a vibrator assembly. The stator assembly comprises a housing (1) having a receiving cavity, a magnet (2) located in the receiving cavity and jointly fixed to the housing (1), and a central magnetic yoke (3) of which at least one end is jointly fixed to the housing (1). The magnet (2) comprises a hollow portion (21) extending along the vibration direction of the vibrator assembly. The vibrator assembly comprises a coil (4) and a mass block (9). When the vibrator assembly vibrates, the coil (4) vibrates along with the vibrator assembly and is inserted into the hollow portion (21) of the magnet (2). The central magnetic yoke (3) runs through the coil (4). An resilient support member (5) is configured to suspend the vibrator assembly in the receiving cavity of the housing (1). According to the linear vibration motor, the magnetism of the magnet can be utilized to the greatest extent, thereby improving the efficiency of utilizing the magnetic line of force of the magnet by the coil, the central magnetic yoke functions as a guide shaft, thereby ensuring the vibration coaxiality of the vibrator assembly.
