摘要： A speaker system for a picture receiver provides for lessening of the casing width of the picture receiver while assuring highly uniform acoustic characteristic at listening points in a sufficiently broad range. The speaker system for picture receiver and its speaker installing method comprises a first speaker for reproducing medium and high range sound at the right and left of the screen of a picture receiver and a second speaker for reproducing medium and low range sound under the screen, wherein the speaker system is set in such place that when a listening point is set at a position a first distance apart from the picture receiver and within a second distance from the front axis at the center of the right and left of the screen, the distance from the first speaker to the listening point is R1, the distance from the second speaker to the listening point is R2, and the crossover frequency is f, then R1, R2 and f satisfy the specified relative formula.

摘要： In a speaker system capable of controlling the directivity, a first pair of speaker units are disposed at a cabinet from face having vertical and horizontal axes, so that the diaphragm centers are located along a line which is parallel with the horizontal axis of the front face. A second pair of speaker units are disposed so that the diaphragm centers are located along a line which is parallel with the vertical axis of the front face. The horizontal distance between the centers of the diaphragms of the first pair of speaker units and the vertical distance between the centers of the second pair of speaker units are different from each other. The center of the line which links the diaphragm centers of the first pair of speaker units and the center of the line which links the diaphragm centers of the second pair of speaker units are located at the same position. A fifth speaker unit may be disposed on the front face of the cabinet at a center of an area surrounded by the first and second pair of speaker units.

摘要： A sound field measuring device uses a measurement signal which has at least one change point and whose frequency spectrum has a shape corresponding to a shape of a frequency spectrum of a background noise. This enables a sound field measurement, which is for measuring an impulse response or transfer function of a sound field space which is a linear time-invariant system to be measured, to be performed with a high S/N ratio over a wide frequency band.
