摘要： A double helix actuator is disclosed that includes a double helix coil wound around a movable proof mass that is enclosed within a magnetic structure. The double helix coil and the magnetic structure are arranged relative to each other so that the magnetic field generated by the entirety of the double helix coil contributes to a linear force direction of the actuator. The double helix actuator produces a greater linear force density compared to traditional racetrack coil actuators, where only a portion of the coil contributes to the linear force. The double helix actuator also produces torque in addition to linear force which allows the double helix to provide unique haptic sensations in a variety of applications.

摘要： A holder is used while attached to a chassis of a vibration generator that moves a vibrator to generate a vibration. The holder includes a vibrator retention unit retaining the vibrator, a fixed unit fixed to the chassis, and an arm. The arm connects the fixed unit and the vibrator retention unit, and the arm supports the vibrator retention unit while the vibrator retention unit can be displaced with respect to the fixed unit. The fixed unit, the arm, and the vibrator retention unit are integrally formed using resin.

摘要： A linear vibration motor includes a housing with a first accommodation space, a vibration unit, an elastic part and a coil assembly fixed on the housing. The vibrating unit includes a support connected with the elastic part, and includes a top wall perpendicularly to a vibrating direction of the vibrating unit, a side wall bending and extending from a periphery of the top wall, a through hole penetrating the top wall, and two separation walls respectively bending and extending from the two opposite sides of the through hole. The top wall and the side wall enclose to form a second accommodation space which is divided by the two separation walls into a main accommodation space and two auxiliary accommodation spaces. The linear vibration motor further includes at least one weight block accommodated and fixed in the auxiliary accommodation spaces, and at least one magnet respectively fixed to the support.

摘要： The present disclosure provides a vibration device, including a stator, an eccentric wheel and an electromagnetic driving assembly. The eccentric wheel rotates around a rotating shaft relative to the stator. The electromagnetic driving assembly includes at least one magnetic element and an induction coil. The at least one magnetic element is disposed on the eccentric wheel. The induction coil corresponds to the magnetic element, and the induction coil is disposed on the stator. When acurrent is applied to the induction coil, the induction coil acts with the magnetic element to generate an electromagnetic force to drive the eccentric wheel to rotate around the rotating shaft, so that the vibration device generates a vibration. The rotating shaft is disposed on the stator.

摘要： The invention discloses a control system for LRA, applicable to an LRA having a speed sensing coil. The control system comprises a signal amplifier, an excitation device, a flow controller, a processing unit, and a driver. The processing unit is connected to the signal amplifier, the excitation device and the flow controller, so as to stop output, output the excitation signal as a driving signal or process the induction signal from the signal amplifier into an appropriate system damping coefficient and output as a driving signal when the flow controller outputs a stop, excitation or braking state signal, respectively.
