Abstract

PURPOSE:To make thin the size and to obtain a flat characteristics over a broad band, by constituting a magnetic circuit through the location of a thin type magnetic circuit single body in matrix and inserting a rectangular voice coil over a straight line magnetic gap. CONSTITUTION:A plurality of thin type magnetic circuit single bodies 20 having two parallel magnetic gaps are located in matrix by arranging the magnetic gap to a straight line to constitute a magnetic circuit. A rectangular voice coil 26 bridged over the adjacent magnetic gaps adjacent to the magnetic circuit is inserted and a flat vibration diaphragm plate 30 is bonded to the voice coil 26.
