MULTIFUNCTION VIBRATION ACTUATOR

摘要

[PROBLEMS] A multifunction vibration actuator having excellent resistance against impact caused by falling etc. and also having a simple structure facilitating assembly. [MEANS FOR SOLVING PROBLEMS] A magnetic circuit constructed from a pole piece, a magnet, and a yoke is supported by using a suspension of a shape where an outer ring section and an inner ring section are connected by a support section. The outer ring section of the suspension is fixed projecting more inward from a housing or from a cover inner wall where a step is provided than the magnetic circuit. The outer ring section limits the range of movement of the magnetic circuit to prevent the inside of a multifunction vibration actuator body from being damaged when it is subjected to impact caused by falling etc. ® KIPO & WIPO 2008
