Loudspeaker control device of coaxial type loudspeaker

Abstract

Abstract PURPOSE:To enlarge capacity of a back-chamber, and to improve a characteristics, by using jointly the control of a center position of a loudspeaker unit, and the fixation of an inside edge of a plane diaphragm type loudspeaker unit. CONSTITUTION:A plane diaphragm 3 is supported by a frame 1 and a frame part 12 of a position control body 11. A downward detaining stepped face 14 is formed on the inside face of the position control body 11 in order to control a position in the front and rear directions of a separable loudspeaker unit 7. Subsequently, this position control body 11 is fixed to a magnetic circuit 6 so that its center line coincides with the center line of a plane diaphragm type loudspeaker unit 2, and thereafter, one side edge of an inside edge 5b of the plane diaphragm 3 is stuck onto the upper face of the frame part 12, and the plane diaphragm type loudspeaker unit 2 is completed.
