Abstract:

PURPOSE: To provide a speaker system in which distortion in sound pressure radiated from an edge can be reduced.
CONSTITUTION: This system is comprised of a first speaker unit 16 provided with a projecting shape roll edge 9, a second speaker unit 17 provided with a recessed shape roll edge 11, a speaker unit 12 for middle/high frequency tone arranged almost in the center of the speaker units 16, 17, and a cabinet 13 on which the speaker units 16, 17 and the speaker unit 12 for middle/high frequency tone are mounted.
