摘要:
The present invention provides a speaker system for picture receiver and its installing method capable of lessening 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.

A speaker grille disposed in front of a speaker having a diaphragm and reproducing the sounds of 1 kHz and higher. The speaker grille is provided with a sound opening which includes a line that opposes to a region extending from the edge portion of a diaphragm to the fixing portion on the outer circumference of the diaphragm of speaker. The speaker grille offers superior sound characteristics, at the same time a sufficient mechanical strength either.

A first feature of the present invention is that the opening of a sound output port (3b) is smaller in area than the opening of a sound input port (3a) in a horn (3). A second feature is that the sound output port (3b) of the horn (3) is located so as not to be in the way of a center axis of sound radiation from a speaker (2). A third feature is that a length L of the horn (3) is set at 370 mm or below. A fourth feature is that the horn (3) is gradually narrowed such that vertical sections thereof from the sound input port (3a) to the sound output port (3b) respectively have areas based on a predetermined rule.
