Abstract

PURPOSE:To distribute sound volume automatically in response to seating position by providing a detecting means detecting the presence or absence of a passenger to the seating position of the passenger and providing an adjusting means adjusting the sound volume based on the result of detection. CONSTITUTION:A means detecting the presence or absence of a passenger at a rear seat is provided and transistors (TRs) Q1, Q2 and resistors R5, R6 adjusting the sound volume of speakers by the output of the said means are provided in an on-vehicle audio equipment of the four-channel stereo system comprising an on-vehicle audio equipment main body 1, amplifiers 2-5, the speakers 6-9, and resistors R1-R4. When a passenger takes a seat on the rear right seat, the TRQ1 is turned on by the output of the detecting means, a right side signal R outputted from the audio equipment main body 1 is divided by the resistors R2, R5 to reduce the sound volume outputted from the speaker 8 for the rear right seat.

のである。As shown in FIG. 2, the speakers 6 and 7 are installed on the right and left sides of the front of the car, respectively, and the speakers 8 and 9 are installed on the right and left sides of the rear of the car, respectively. Further, the cylinder 10 and the bag 16 are housed in the rear right seat 1B, and the cylinder 11 and the bag 17 are housed in the rear right seat 19.

タＱ１はオン状態となる。For example, if an occupant is seated on the rear right seat 1B of the rear seats, the bag 16 is pressed, air flows into the cylinder 10, and the sliding plate 12 slides in the direction of the arrow. Then, when the sliding plate 12 and the contact 14 come into contact, a power supply voltage of 10 B is applied to the base of the transistor Q1, and the transistor Q1 is turned on.

して聞こえることになる。By turning on the transistor Q1, the right side signal R output from the audio device main body 1 is connected to the resistor R2,
The voltage is divided by R5 and output from the speaker 8 via the amplifier 4. That is, when an occupant is seated in the rear right seat 18, the volume output from the speaker 8 is % lower than when no occupant is seated in the rear right seat 18. In this way, when an occupant is seated in the rear right seat 18, the volume output from the speaker 8, which is located close to the occupant, becomes low. , 9 can be heard in a balanced manner.

contacts and turns on the transistor Q2, which causes the left signal 4 output from the audio device main body 1 to
The voltage L is voltage-divided by resistors R4 and R6, and outputted from the speaker 9 via the amplifier 5. Therefore, when an occupant is seated in the rear right seat 19, the volume output from the speaker 9 becomes low, so that the volume is output from the speakers 8 and 9 to the occupant seated in the rear right seat 19. The sound will be heard in a well-balanced manner.
