Abstract

PURPOSE:To reduce the number of parts to facilitate assembling by obtaining a flat characteristic up to a band over an audible band by making functions of a horn and an equalizer into one body. CONSTITUTION:In speaker main body part 11, a voice coil which is made into one body together with a diaphragm is arranged movably in the cylinder axis direction in the cylindrical space of the magnetic circuit of a yoke and a magnet. Main body part 11 is mounted on flange-form base edge part 121 of horn body 12, and horn body 12 has the center part of base edge part 121 concaved spherically in a part opposite to the diaphragm, and slit-form apertures 121b arranged radially independently of one another are formed for spherical part 121a. Seven apertures 121b have the sectional area increased gradually according as going toward flange- form edge part 122, and they are made into a circle, where all apertures 121b are continuous, near the end part, and plural protrusions 121c whose front view is a petal are formed into one body between respective apertures 121b.
