Abstract

PURPOSE:To improve the efficiency, by placing a pair of plane vibration diaphragms in the throat part of a horn part and by arranging them oppositely to each other in a direction parallel with the horn axis. CONSTITUTION:As a speaker unit 32 connected to the throat part of a horn part 31, a pair of condenser type speaker units 321 and 322 are arranged which consist of a pair of plane vibration diaphragms 331 and 322 connected to upper and lower ends of the throat part of the horn 31 in parallel with the horn axis and a pair of fixed poles 341 and 342 provided oppositely to each other at the interval of a prescribed distance outside diaphragms 331 and 332. That is, the speaker is so constituted that acoustic waves are given to the horn from the space between a pair of diaphragms 331 and 332 facing to each other, and therefore, a diameter (d) of the throat of the horn part 21 becomes small.
