Abstract

PURPOSE:To prevent or suppress the deterioration of sound pressure characteristics of treble compass by extending several openings for phase equalization, residing before a diaphragm to the opening part at the output side of the horn. CONSTITUTION:Bulkheads 91 to 97 are provided which are installed in the horn, extend continuously from air gaps before the diaphragm to the horn opening part, and are arranged in the circumferential direction of the horn, and parts are slotted which correspond to air gaps between bulkheads. Respective bulkheads 91-97 are so formed that the size in the direction perpendicular to the sound axis, namely, in the horn diameter direction will increase gradually from the slot part to the horn opening part while the thickness in the circumferential direction centering on the sound axis decreases gradually; and openings 101 to 107 formed between bulkheads have the area of each surface perpendicular to the sound axis increasing from the slot part to the horn opening part according to an exponential function.
