    Abstract: The quality of sound genrated is improved and the appearance is also improved. A loudspeaker diaphragm (10) has at its slant portion a projection shown representatively by an edge (4) and a recess shown representatively by an edge (5). The projection is formed radially from the center and curved toward the edge in the circumferential direction. Therefore when the loudspeaker diaphragm (10) vibrates with a large amplitude and the center moves toward the bottom, a rotational force is exerted on the air tending to gather at the center and thereby the press against the center is mitigated. The loudspeaker diaphragm (10) has a three-dimensional structure similar to a screw propeller and is reinforced as a whole to suppress split vibration. The loudspeaker diaphragm (10) is produced by injection molding largely of polypropylene. A variety of colors can be easily given to it when produced. The color and its peculiar structure like a screw propeller impart strong impression.

    Abstract: A loudspeaker apparatus utilizing a ribbon diaphragm (12) which is capable of transforming an electrical signal into an audio acoustical signal. The diaphragm includes a first side (86) and a second opposite side (112). First and second magnets (36, 38) are also employed in the present invention and are mounted to the edges of the diaphragm (12) such that the diaphragm (12) lies in the magnetic field generated by the pair of magnets (36, 38). A first plurality of spaced magnetic plates (84) are stacked and extend continuously from the first magnet (36) to the second magnet (38) at the first side (86) of the diaphragm. The first plurality of plates form a throat-shaped cavity (90) of a pre-determined size. A second plurality of spaced magentic focusing plates (114) are stacked on the second side (112) of the diaphragm in the same manner. A plurality of sound damping shims (102), each interposes each of the first plurality of magnetic focusing plates on the sides of the throat-shaped cavity (90). An acoustic coupler or horn (128), each interposes may be easily attached to throat-shaped cavity (90) to enhance the lower acoustical response range.
