Patent ID: 8041047

Claim:
A sound inputting and outputting apparatus for being connected to an external apparatus which includes a noise cancel signal production section for producing, in response to a noise signal inputted thereto, a noise cancel signal for reducing the noise signal, a storage section and a reproduction section for reproducing sound data stored in the storage section, the sound inputting and outputting apparatus comprising: a first auricle mounting section including a first microphone and a first speaker; a second auricle mounting section including a second microphone and a second speaker; and a plug including a first conductor configured to output a first noise signal to the external apparatus in response to first noise inputted to said first microphone, a second conductor configured to output a second noise signal to the external apparatus in response to second noise inputted to said second microphone, a third conductor configured to transmit a first synthesis signal of a first noise cancel signal produced by the noise cancel signal production section in response to the first noise signal and a first sound signal reproduced by the reproduction section to said first speaker, a fourth conductor for grounding, and a fifth conductor configured to transmit a second synthesis signal of a second noise cancel signal produced by the noise cancel signal production section in response to the second noise signal and a second sound signal reproduced by the reproduction section to said second speaker, said plug being configured to be inserted into a jack provided on the external apparatus to establish connection thereof to the external apparatus.
