Patent ID: 7509192

Claim:
An in-vehicle mount type AV system which is mounted in a vehicle and comprises a control unit, plural acoustic output units whose acoustic effects are variable, and a display unit, characterized by comprising: an angle varying unit for varying an angle of a display face of the display unit; an angle detecting unit for detecting the angle varied by the angle varying unit, wherein the control unit controls the acoustic effects of the respective plural acoustic output units on the basis of the varied angle detected by the angle detecting unit; a tilt angle detecting unit for detecting a tilt angle of a backrest of a seat; and a front and rear movement distance detecting unit configured to detect the movement distance in a front and rear direction from a reference position of the seat, wherein the control unit executes the acoustic effect control on the basis of the tilt angle detected by the tilt angle detecting unit and the movement distance detected by the movement distance detecting unit.
