Abstract:
1. A device to transmit an audio signal having a first energy and a second energy different from the first energy, the device comprising: at least one light source configured to transmit the audio signal with at least one wavelength of light; at least one detector configured to detect the audio signal and generate at least one electrical signal in response to the at least one wavelength of light; a transducer supported with and configured to vibrate at least one of an eardrum, an ossicle or a cochlea; active circuitry coupled to the at least one detector and the transducer to drive the transducer in response to the electrical signal; and circuitry coupled to an input and the at least one light source, the circuitry configured to receive the audio signal and determine the first energy of the audio signal and the second energy of the audio signal, the circuitry configured to output a first amount of low frequency light energy bias from the at least one light source at a first time and a second amount of low frequency light energy bias from the at least one light source at a second time to power the active circuitry, the first amount of low frequency light energy bias different from the second amount of low frequency light energy bias in order to accommodate substantially different power consumption of the active circuitry and the transducer in response to the first energy different from the second energy.
