HEADPHONE OR HEADSET AND AUDIO PRODUCING DEVICE TO WHICH THE HEADPHONE OR HEADSET IS INTENDED TO BE CONNECTED

摘要

An audio system comprises an audio producing device and a headphone or a headset. The audio producing device transmits to the headphone or the headset left and right analog signals intended respectively for left or right analog speakers, and transmits to the headphone or the headset a power supply signal. The headphone or the headset comprises at least one digital microphone and means for superimposing digital data, resulting from sound captures performed by each digital microphone, on top of said left analog signal or on top of said right analog signal or on top of said power supply signal. The audio producing device further comprises means for separating the digital data from said left analog signal or from said right analog signal or from said power supply signal for further processing by the audio producing device. The audio producing device further comprises means for superimposing a clock signal intended to drive each digital microphone on top of said left and/or right analog signal. The headphone or the headset further comprises means for separating the clock signal from said left and/or right analog signal to drive each digital microphone.

主权项

1. An audio system comprising an audio producing device and an audio device of one of a headphone or a headset type, the audio device comprising left and right analog speakers, the audio producing device being adapted to transmit to the audio device left and right analog signals respectively to the left or right analog speakers, the audio producing device being further adapted to transmit to the audio device a power supply signal, wherein:
the audio producing device further comprises first processing logic configured to separate the digital data from one or more of said left analog signal, said right analog signal or said power supply signal for further processing by the audio producing device; the audio producing device further comprises second processing logic configured to superimpose a clock signal arranged to drive at least a digital microphone on top of one or more of said left or right analog signal; and the audio device further comprises a digital microphone and third processing logic configured to superimpose, on top of one or more of said left analog signal, said right analog signal or said power supply signal, digital data resulting from sound captures performed by the digital microphone; the audio device further comprises fourth processing logic configured to separate the clock signal from said one or more of left or right analog signal to drive each digital microphone.
