    Abstract: PURPOSE: An acoustic sound controlling method of a line array speaker for a vehicle is provided to divide acoustic sound space between a driver and passengers without the use of the individual acoustic device by including an individual acoustic sound space inside a vehicle. CONSTITUTION: A first bright area and a first dark zone are set in the entire acoustic sound domain of the sound field system. The sound pressure of the sound field system is calculated. The sound field system is normalized by using the calculated sound pressure of the sound field system. A second bright area and a second dark area are set in the entire acoustic sound domain by using the sound pressure of the normalized sound field system. An eigen value and an eigen vector are calculated. The eigen value and the eigen vector maximize difference between the output energy compared to the input energy of the calculated second bright area and the output energy compared to the input energy of the second dark area. The eigen vector is determined to as the volume velocity of the sound field system.

    Abstract: PURPOSE: A continuous variable valve lift device is provided to regulate the opening and lift distance of a valve easily and precisely without moving a drive cam. CONSTITUTION: A continuous variable valve lift device comprises a control shoe(300), a drive cam(400), and a moving mechanism(500). The control shoe has a slide surface(310) on one side contacting a rocker arm(200) for opening and closing an engine valve, and presses the rocker arm to move. The moving mechanism is contacted with the drive cam and provided with the torque to move the control shoe. The slide surface is composed of a zero lift section which doesn't move the rocker arm, and low and high lift sections to move the rocker arm at different angles.

    Abstract: PURPOSE: A variable valve lifting device is provided to control deviation adjustment between valves and to increase assembility using a connecting pin and a wall part of a cam carrier. CONSTITUTION: A variable valve lifting device comprises an input cam(110), a valve opening/closing part(200), an eccentric shaft(300) and a connection part(400). An input shaft(100) has the input cam. The eccentric shaft is equipped in the input shaft in parallel. The connection part opens and closes the valve opening/closing part after receiving rotation of the input cam. The rotation center of a connecting part can be changed with the eccentric shaft.
