Document Type and Number:
WIPO Patent Application WO/2017/010610
Kind Code:
A1
Abstract:
Disclosed is a headset comprising: a first head having a first speaker unit; a second head having a second speaker unit and a microphone disposed at a position inside the outer ear canal of a user when worn; a communication unit for communicating with a mobile device; and a controller for stopping an audio signal output to the second speaker unit when a audio feedback capture signal is received from the mobile device through the communication unit. Accordingly, noise from the outside can be effectively screened, and also, a user's voice can be sufficiently captured in order to prevent audio feedback and echo from occurring at the source, so that clean sound can be provided to the user and voice recognition accuracy can be increased when the headset is applied to a voice recognition device.
