Abstract:
1. An electro-optical headset comprising: an electro-optical interface for receiving a first electrical signal representative of first audio and for producing a first modulated light signal based on the first electrical signal, and for receiving a second modulated light signal and demodulating the second modulated light signal to produce a second electrical signal representative of second audio; an optical link having a first end and a second end, the first end being coupled to the electro-optical interface for receiving the first modulated light signal and for transmitting the second modulated light signal; an optical receiver coupled to the second end of the optical link for receiving the first modulated light signal, and for demodulating the first modulated light signal to produce a third electrical signal representative of the first audio; a headset speaker element electrically connected with the optical receiver for receiving the third electrical signal and producing first sound waves based on the third electrical signal; and a microphone element coupled to the second end of the optical link for receiving the first modulated light signal and for transmitting the second modulated light signal, and for modulating the first modulated light signal to produce the second modulated light signal representative of the second audio; wherein the microphone element comprises:
