Abstract

A wireless headset has a body, an ear clip, and at least two devices for converting at least two different sources of energy into electrical power. The body includes an RF integrated circuit in electrical communication with an antenna and a baseband circuit, the baseband circuit being in electrical communication with a microphone and a speaker. The at least two devices for converting at least two different sources of energy into electrical power are in electrical communication with the RF integrated circuit and the baseband circuit. The ear clip is engaged to the body. The at least two sources of energy are selected from the group consisting of solar energy, thermoelectric energy, piezoelectric energy, and vibration energy.

Claims

1. A wireless headset comprising:

a body comprising a radiofrequency (RF) integrated circuit in electrical communication with an antenna and a baseband circuit, the baseband circuit in electrical communication with a microphone and a speaker;

an ear clip engaged to the body;

a first adapter configured to engage a second adapter of a cellular phone and receive power from the cellular phone;

a plurality of devices for converting at least two different sources of energy into electrical power, the plurality of devices being in electrical communication with the RF integrated circuit and the baseband circuit, wherein the at least two different sources of energy are selected from the group consisting of solar energy, thermoelectric energy, piezoelectric energy, and vibration energy,

a first one of the plurality of devices comprising a first microgenerator configured to convert vibration energy to electrical power, wherein the ear clip comprises the first microgenerator.

2. The wireless headset of claim 1 further comprising a second microgenerator, wherein the first microgenerator is oriented on a first axis, the second microgenerator is oriented on a second axis, and the first axis is not parallel to the second axis.
