The present invention discloses a method and an apparatus for improving the call quality of a hands-free call device, and a hands-free call device. The hands-free call device comprises a transmitter end composed of a main microphone and at least one auxiliary microphone. The method comprises: scanning within an initial first collection angle of a transmitter end; after a voice feature signal is scanned within the first collection angle, according to a direction of the voice feature signal, determining a second collection angle smaller than the first collection angle within the first collection angle; and calibrating the transmitter end to a direction determined by the second collection angle. In this method, voice pickup is conducted using a relatively small voice protection angle, so that the interference from ambient noise can be greatly reduced, to achieve the purpose of improving the transmission signal to noise ratio, thus the directivity of a voice in a hands-free call device during a call is more clear, which improves the call quality. |
