Title: On-vehicle acoustic device
Inventor: YAMAZAKI SHINICHI
IPC: H04R5/02
Filed: 1993-12-03
Abstract: PURPOSE:To provice the on-vehicle acoustic device capable of taking the optimal frequency balance even when a listening position is changed by correcting the sound pressure frequency characteristic at each listening position. CONSTITUTION:The high area of the acoustic signal is corrected by equalizer circuits EQ11-14 so that the high area is increased according to the frequency characteristic of the speaker as the voice pressure frequency characteristic from speakers SP1-SP4 at the selected listening position is to make flat, that is, the angle which crosses at right angles with the straight line connecting the speaker and the listening position becomes large. Further, the level of each acoustic signal is corrected by acoustic adjustment circuits VR11-14 so that the sound pressure level from each speaker becomes the same at the selected listening position. Thus, the deviation of the sound field due to the asymetric stereo listening at each listening position in a car and the deterioration of the sound image localization are prevented and the optimal frequency balance in the required listening position in the car can be obtained.

IPC: H01L21/822
Filed: 1988-12-02
Abstract: PURPOSE:To reduce racing between flip-flop circuits which makes up a scan-path without accompanying increase in number of gates as well as electricity consumption by installing a wiring channel to be used exclusively for scan-path signals directly below a power source wiring region. CONSTITUTION:A scan-path is made up by a flow: F/F 10 11 12 13 and its signal wiring regions 14-16 are installed all directly below a three-layer power source wiring region 17. As a result, a cross over factor between the signal wiring regions 14-16 and the three-layer power source wiring region 17 reaches 100% and a large wiring capacitance is given to the above wiring. On the other hand, a signal wire 18 for ordinary moments, that is, the movements other than a scan movement uses 1/2 layer wiring as well. However, its wire is installed to places other than directly below parts of the three-layer power source wiring 17 to make its cross over factor small. Then delay time of signal wiring regions 14-16 which are used for the scan movement of becomes larger than that of the signal wire 18 for the ordinary movements.
