APPARATUS FOR AUTOMATIC LISTENING OF PORTABLE SOUND SYSTEM USING CAR STEREO

摘要

PURPOSE: An apparatus for automatic listening of a portable sound system using a car stereo is provided to replay audio data of portable sound systems such a portable CDP(Compact Disc Player), a portable cassette, and an MP3 player by using a car stereo. CONSTITUTION: A cigarette jack plug(110) provides an electric power from a cigarette jack of a vehicle to a solenoid drive circuit portion, a sound transmission circuit portion, and a solenoid(130). An earphone plug(120) is used for receiving an output of a sound signal from a portable sound system. The solenoid(130) is adhered to an inside of a combination device(100) in order that a particular memory selection button of a car stereo is pushed by an output signal of the portable sound system. A projection(102) is formed at the combination device(100). The projection pin is used for preventing escape of the combination device(100) from an insertion groove of the car stereo.
