Abstract
The present invention is directed to an acoustic resonator within an acoustic chamber such as a stringed instrument body. The acoustic resonator is provided with a piezoelectric material. The kinetic energy derived from the acoustic chamber creates vibrations of sound producing a corresponding or sympathetic mechanical vibration to the piezoelectric material. As a consequence, the piezoelectric material will generate electrical energy which will undergo conditioning by energy harvester electronics. The conditioned electrical energy is used to provide power to multiple devices including on-board electronics or a USB charging port.
Claims11
A body for an acoustic chamber, said body including a bottom circumscribed by a side wall, said body having mounted therein an energy harvester device, said energy harvester device comprising:
- an acoustic resonator configured to produce a mechanical vibration at a resonate pitch when set vibrating by said body;
- a coupler for mounting said acoustic resonator within said body;
- a piezoelectric material disposed on said acoustic resonator, said piezoelectric material is configured to produce an electrical charge in response to said mechanical vibration;
- an energy harvester electronics configured to receive said electrical charge, said energy harvester electronics conditioning said electrical charge into a regulated output voltage;
- said body further comprises one of a charging port or on-board electronics, wherein said regulated output voltage is configured to supply power to one of said charging port or on-board electronics.
