Remotely powered wireless microphone
First Claim
Patent Images
1. A wireless microphone circuit, comprising:
- a resonant circuit tuned to a transmit frequency, the resonant circuit to capture and modulate signal bursts at the first transmit frequency; and
a re-transmitter circuit to transmit the modulated signal, wherein the wireless circuit receives energy needed to operate the resonant circuit solely via the captured signal bursts independent of a locally pre-stored power supply.

Abstract
Various methods, apparatuses, and systems in which a remotely powered wireless microphone are described. The remotely powered wireless microphone circuit includes a resonant circuit tuned to a transmit frequency of a receiver station. The resonant circuit captures signal bursts from the receiver station. The resonant circuit includes a capacitive microphone element to modulate a resulting ringing of the circuit upon being energized by the signal bursts. The wireless microphone circuit also includes a transmitter circuit to transmit the modulated signal.
