Abstract

PURPOSE: To add safety driving by installing a microphone so as to face to the outside of the car interior and allowing the sound collected to be output to the inside of the car.
CONSTITUTION: When switches 17W19 are at the position shown on the drawing, if a tuner 20 is operated, the output signal is output to a speaker 4 or a headphone 22 through an amplifier 2. In order to operate a tape recorder 3 as a substitute for the tuner 20, the movable piece 18c of a switch 18 is connected with a fixed contact 18b. When the outside noise is monitored, switches 18 and 19 are set at the position shown on the figure, and the movable piece 17c of a switch 17 is connected with a fixed contact 17b. Then, the outside noise is gathered from the microphone 17 installed on the outside wall part of a door 6 and input to the amplifier 2, and can be monitored at the same time by the speaker 4 and the microphone 22.
