▎ 摘　　要

NOVELTY - The actuator comprises two springs connected between a housing and a moving element such that one of the springs crosses the other of two rotor springs (1106) without contacting the other spring. The drive component causes the moving element to move along an arc-shaped path that subtends an angle of between 30 and 70 degrees. The two springs have an asymmetric profile with a pair of parallel edges shorter than the edges of another pair of edges. The mounting edge of each spring is proximal to an attachment location on the housing. The moving element has two weights mounted to sides of a planar platform. USE - Non-linear haptic actuator e.g. linear-resonant vibration module (LRVM) and unbalanced-electric-motor (UEM) actuators, for use in an electromechanical device, appliance and system. ADVANTAGE - The non-linear haptic actuators can be designed and manufactured to be more space efficient than unbalanced-electric-motor and linear-resonant vibration modules and, because most of the frictional forces produced in unbalanced electric motor and linear resonance vibration modules are eliminated from nonlinear actuators. The nonlinear vibration actuators are generally more power efficient and robust. The vibration-generating units for incorporation into many consumer appliances, devices, and systems can be more efficient and capable. The rotor, rotor-suspension, and spring subsystem can efficiently generate vibrational forces in various types of devices and appliances.
