    摘要: A speaker system for use in an automobile vehicle, comprises: pair of side speakers disposed on left and right sides in a front section within the automobile vehicle; a central speaker disposed in a middle position between the two side speakers; a pair of delay circuits connected on two signal lines leading to the side speakers disposed on the left and right sides within the vehicle; an adder connected between the left and right channels to add together the electric signals transmitted from the left and right channels so as to produce a sum signal; and a band pass filter connected on a signal line leading to the central speaker, said band pass filter being constructed and adjusted to eliminate a high frequency signal component. The sum signal fed from the adder is passed through the band pass filter before being applied to the central speaker.

    摘要: An ultrasound image forming method comprises a first step of receiving a first signal reflected from the object, a second step of obtaining an aberration correction value based on the first signal thus received, a third step of receiving a second signal reflected from the object when a second ultrasound corrected based on the aberration correction value is transmitted to the object, and a fourth step of forming an image from the aberration correction value and the second signal. The center frequency of the second ultrasound is between 0.5 MHz and 20 MHz, the center frequency of the first ultrasound is between 3/16 and 9/20 of the center frequency of the second ultrasound. By this method, an accurate aberration correction value can be obtained and an ultrasound imaging with high resolution can be achieved even if aberrations are large and difficult to correct.
