Vibration Component that Harvests Energy for Electronic Devices

摘要

An energy harvesting component for use in a portable electronic device includes a housing, a mass element within the housing, an energy transducer positioned inductively proximate the mass element, and a coupling between the mass element and the housing. In a first mode, the energy harvesting component may convert mechanical energy from agitation of the portable electronic device to electrical energy for use by the electronic device and, in a second mode, the energy harvesting component may induce movement of the mass element to provide haptic feedback.
