Abstract

A percussion instrument comprising an energy harvesting device is disclosed, embodiments take the form of a percussion shaker and a drum, various implementations are disclosed for harvesting kinetic energy from motion imparted to the instrument and converting it to electrical energy for later use and for transfer to an external device.

Claims

1. A shaken idiophone, comprising:

a means for converting kinetic energy imparted to the shaken idiophone into electrical energy, wherein the kinetic energy is imparted through shaking of the shaken idiophone, wherein the means for converting kinetic energy is configured to convert the kinetic energy recovered from cyclical oscillations in the idiophone into electrical energy, wherein the means for converting kinetic energy comprises at least one coil and an armature;

a means for storing the electrical energy for later use;

a means for transferring the stored electrical energy to an externally connected electrical device, wherein the means for converting kinetic energy is electrically connected to the means for storing the electrical energy, in order that an electrical current can be converted into stored electrical charge in the means for storing the electrical energy;

a bridge rectifier located between the means for converting kinetic energy and the means for storing the electrical energy, to rectify an output from the at least one coil;

a hollow body having at least one interior rattle cavity, wherein the hollow body further comprises an energy convertor housing portion for housing the means for converting kinetic energy and the means for storing the electrical energy; and

a divider for dividing the energy convertor housing portion from the at least one interior rattle cavity, wherein the hollow body contains at least one rattle portion, and the energy convertor housing portion is located adjacent the at least one rattle portion.

2. The shaken idiophone of claim 1, wherein the shaken idiophone is at least one of a percussion instrument, a musical instrument, and a child'"'"'s toy.

3. The shaken idiophone of claim 1, further comprising a main body forming a principal structure of the shaken idiophone, wherein the means for converting kinetic energy is configured to convert the kinetic energy imparted to the main body of the shaken idiophone into electrical energy.

4. The shaken idiophone of claim 3, wherein the means for converting kinetic energy is a piezo-electric element.

5. The shaken idiophone of claim 1, further comprising a geo-location means.

6. The shaken idiophone of claim 1, further comprising a wireless data connection means.

7. The shaken idiophone of claim 1, wherein the means for converting kinetic energy further comprises a linear barrel, in which the armature can freely oscillate, wherein the barrel is orientated along a principal axis of movement of the shaken idiophone, in order that a maximum amount of the kinetic energy is imparted to the armature in use, and wherein the at least one coil and the armature are arranged such that movement of the at least one coil and the armature with respect to one another due to the motion of the shaken idiophone, creates an electrical current in the coil.

8. The shaken idiophone of claim 7, further comprising biasing means situated at at least one end of the barrel for biasing against the movement of the armature towards the end of the barrel, wherein the biasing means comprises at least one of a deformable member, a spring, and a rubber plug.

9. The shaken idiophone of claim 7, further comprising sound damping means for damping sound created by an impact of the armature against an end of the barrel.

10. The shaken idiophone of claim 1, wherein the armature is at least one of a magnet and a neodymium magnet.

11. The shaken idiophone of the claim 10, wherein the biasing means comprises magnets orientated to repel the armature.

12. The shaken idiophone of claim 1, further comprising a battery charge indicator for indicating the battery charge level to a user, wherein the battery charge indicator comprises a first light source, wherein the first light source illuminates when the means for storing the electrical energy reaches a first predetermined level of charge;

and a second light source, which illuminates upon user input when the charge in the means for storing the electrical energy is above a second predetermined threshold level of charge.

13. The shaken idiophone of claim 12, wherein the battery charge indicator further comprises an audible output device.

14. The shaken idiophone of claim 1, further comprising a photovoltaic cell and a boost convertor, and wherein at least one of the means for converting kinetic energy and the photovoltaic cell is connected to the means for storing the electrical energy via the boost convertor.

15. The shaken idiophone of claim 1, wherein the means for transferring the stored electrical energy is arranged to transfer the energy wirelessly.

16. The shaken idiophone of claim 15, wherein the means for transferring the stored electrical energy is arranged to transfer the energy through inductive coupling.

17. The shaken idiophone of claim 1, wherein the means for converting kinetic energy further comprises a piezo-electric element.
