1. A vocal sound input apparatus for an automotive vehicle, comprising:
- a receiving microphone; and
a noise collecting microphone, both of the receiving microphone and the noise collecting microphone being integrally mounted within a microphone assembly at a predetermined portion on a vehicle body in such a manner that a sensitivity direction of the receiving microphone is opposite to a sensitivity direction of the noise collecting microphone, wherein;
the sensitivity direction of the receiving microphone is oriented towards inside of a vehicular passenger compartment to collect vocal signals from the passenger compartment,the sensitivity direction of the noise collecting microphone is oriented towards a space between a vehicle body outer plate and a wall of the vehicular passenger compartment,the noise collecting microphone is disposed in the space between the vehicle body outer plate and the wall of the vehicular passenger compartment, and configured to collect noise in the space between the vehicle body outer plate and the wall of the vehicular passenger compartment,the noise collecting microphone is insulated to prevent the sound signals from the passenger compartment from entering the noise collecting microphone, andthe sound signals collected by the receiving microphone and the noise collected by the noise collecting microphone are combined to generate an output signal.
