ENERGY HARVESTER DEVICE FOR IN-EAR DEVICES USING EAR CANAL DYNAMIC MOTION

摘要

An energy harvester device located into an in-ear device and harvesting energy from dynamic motion of the wall of the outer ear canal receiving the in-ear device therein, with an external sheath of the in-ear device generally assuming the contour of the ear canal wall. The energy harvester device has an energy harvesting module mounting on an inner portion of the in-ear device adjacent the external sheath, and is at least partially elastically deformable under a displacement of the ear canal wall to generate energy corresponding to the displacement of the wall. An energy storage module mounts onto the in-ear device and connects to the energy harvesting module to receive energy there from and supplying the stored energy to an electronic device of the in-ear device. The in-ear device having the energy harvester device therein is also part of the present invention.

主权项

1. An energy harvester device for positioning into an in-ear device and harvesting energy from dynamic motion of a wall of an outer ear canal receiving the in-ear device therein, the in-ear device being adapted to be placed inside the outer ear canal of a user and having an external sheath substantially assuming a contour of the wall of the outer ear canal, said energy harvester device comprising:
an energy harvesting module for mounting on an inner portion of the in-ear device adjacent the external sheath, said energy harvesting module being at least partially elastically deformable under a displacement of the wall of the outer ear canal and generating energy corresponding to the displacement of the wall; and an energy storage module for mounting on the in-ear device and connecting to said energy harvesting module to receive energy therefrom, said energy storage module storing the received energy and being adapted to supply the stored energy to an electronic device of the in-ear device.
