    摘要： A nondirectional acoustic generator includes two acoustic generator units which are disposed facing each other as near as possible to the extent that diaphragms thereof do not become in contact with each other, drive units of the acoustic generator units being connected in series or in parallel to drive the acoustic generator units in phase and generate air compression sound waves which are radiated in the circumferential direction of the diaphragms.A speaker system includes a plurality of nondirectional acoustic generators coaxially disposed so as to align the centers of respective diaphragms and make the phases at sound generating areas coincident with each other.

    摘要： In an electroacoustic converter, center pole and top plate which constitute a magnetic circuit are mechanically abutted against each other by interposing an air gap defining member therebetween. The air gap defining member is a projection provided on the center pole or top plate, otherwise non-magnetic ring-like sleeve covered on the center pole or top plate. An air gap in the magnetic circuit can be precisely defined by the air gap defining member without using any alignment tool in its assemble process.
