Abstract

A handsfree call apparatus includes: a speaker held in the vicinity of a user's ear by a holding unit with a speaker unit thereof not being attached to a baffle board so as to mix sounds emitted from the front and back of a diaphragm thereof; a microphone, which is provided to a region where sounds emitted from the front and back of the diaphragm of the speaker are mixed and canceled out, configured to collect the call voice of the user; an output unit configured to output a call voice signal of the user from the microphone to transmit this to a call partner; and an input unit configured to receive a call voice signal from the call partner to supply this to the speaker.

Description

technical field [0001] The present invention relates to a hands-free talking device enabling hands-free talking, an acoustic reproduction device with a hands-free talking function, and a hands-free talking method. Background technique [0002] Hands-free talking devices have been proposed, whereby a user can perform talking without holding a handset of a telephone. In particular, for driving safety, an in-vehicle hands-free device has also been proposed, whereby a driver can perform a hands-free call. [0003] Regarding such in-vehicle hands-free devices, for example, such as figure 1 As shown, there is proposed an in-vehicle hands-free device in which a microphone 102 for sending a caller (in this case, a driver) 101 is attached to a sun visor 103 provided on the inner side of the front glass of the vehicle. In this case, the speaker used for the acoustic reproduction of the audio played by its in-vehicle audio playback device may be used for the acoustic reproduction of ...
