Abstract

PURPOSE:Not only to reduce the minimum resonance frequency but also to remove an unnecessary high band, by radiating a sound of the front of a speaker diaphragm in one of the right angle direction against the vibrating direction of the diaphragm, and radiating a sound of the reverse side of the diaphragm in the direction different from the foregoing. CONSTITUTION:A round hole 14 of the bottom plate 13 is fitted into the magnetic circuit 16, a supporting piece 15 is firmly pressed against the lower face of a magnet 19, a rectangular external frame 21 is fitted into the outer circumference of the circuit 16, in the center of this external frame 21 is provided a notch 22 for fitting the magnet 19, and in one side of the notch 22 is provided a resounding hole 23 of the reverse side of the diaphragm 26. Moreover, on the external frame 21 is fixed the diaphragm 26 having a voice coil 25 which has been fitted into a magnetic gap 24 of the circuit 16, on which is attached a cover 27 which has provided side plates on three sides of the ceiling board, the resounding hole 23 of the external frame 21 and the resounding hole 28 of the diaphragm front board of the side plate of the cover 27 are turned in the different direction by 180 deg., and also the diaphragm 26 is made to resound in the different direction as to the front and the reverse side. Moreover, a back cavity by a case is connected to the resounding side of the diaphragm reverse side, and not only the minimum resonance frequency can be reduced but also an unnecessary high band can be removed.
