Abstract

Звукоизлъчвател, изграден от един или няколко звукоизлъчвателни елемента, при което един звукоизлъчвателен елемент съдържа най-малко три простии/или сложни високоговорителя, характеризиращ се с това, че поставените над излъчвателната повърхнина на високоговорителите поне три равнини сключват помежду си ъгъл, чиято стойност се отклонява от 180', и пресечените линии на тези равнини са успоредни помежду си, като същите равнини имат начупена линия, пресечена с перпендикулярната равнина на пресечните линии и симетричните оси на излъчването на отделните съседни високоговорители, респ. Тяхната проекция в споменатата перпендикулярна равнина, се пресичат една с друга последователно в пресечни точки пред начупената линия и в пресечни точки зад начупената линия, докато центровете на излъчването на съседните високоговорители са на по-малко разстояние един от друг от десеткратната дължина на звуковата вълна, отговаряща на горната гранична честота на звуковочестотния обхват. Авторските претенции са формулирани в 7 точки.A sound emitter made up of one or more sound emitting elements, where one sound emitting element contains at least three simple/or complex loudspeakers, characterized in that at least three planes placed above the emitting surface of the loudspeakers form an angle with each other, the value of which deviates of 180', and the intersecting lines of these planes are parallel to each other, and the same planes have a broken line intersected by the perpendicular plane of the intersecting lines and the symmetrical axes of radiation of the individual adjacent loudspeakers, respectively. Their projection in the said perpendicular plane, intersect each other successively at points of intersection in front of the broken line and at points of intersection behind the broken line, while the centers of radiation of the adjacent loudspeakers are less apart than ten times the length of the sound wave, corresponding to the upper limit frequency of the audio frequency range. The author's claims are formulated in 7 points.
