ACOUSTIC HEADSET WITH BUILT-IN DIGITAL AND ANALOG COMPONENTS FOR DUPLEX COMMUNICATION Russian patent published in 2019 - IPC H04R1/10 

FIELD: acoustics.

SUBSTANCE: invention relates to acoustics, in particular to headphones. Acoustic headset for providing a hearing protection device comprises cups of headphones with speakers, a microphone, a headband, a digital component for transmitting and receiving audio messages of digital wireless communication, and one of the earphone cups comprises an analogue component for transmitting and receiving analogue wireless communication audio messages. Headset is configured to output a first audio signal to speakers built into the headphones cup, based on the incoming audio message of digital wireless communication received by the digital component, wherein the acoustic headset is further configured to, in response to the analogue input of the incoming audio message of the analogue wireless communication, interrupt the first audio signal in the selected one of the said built-in speakers, as well as with possibility of outputting the second audio signal to said selected speaker based on said incoming audio message of analogue wireless communication with simultaneous continuation of output of first audio signal to non-selected said built-in speakers.

EFFECT: technical result is providing both digital and analogue duplex communication with simultaneous reduction of weight of communication equipment and simplification of design.
