A multi-driver transducer having a symmetrical magnetic circuit and a symmetrical coil circuit, where one or more pieces of circular or annular partitions made of non-magnetic materials are used to bond two or more sets of dual magnetic gap, dual coil driver units (01 or 02) into one integrated magnetic core. Constituted between an inner circumferential face or an outer circumferential face of one or two tubular magnetic yokes embedded in an open-end tubular thin wall of the bracket and lateral circumferential faces of an upper plate and of a lower plate of the magnetic core are four or more coaxial isodiametric annular magnetic gaps, the four or more coaxial and isodiametric annular magnetic gaps having inserted therein four or more coaxial and isodiametric coils are to govern winding direction, connection method, and necessary technical characteristics of the coils, thus constituting the multi-driver transducer having one or more pairs of mutually-repelling magnets, the symmetrical magnetic circuit, and the symmetrical coil circuit. Counter-electromotive force and inductance acquired via induction by the transducer during working process are mutually canceled. The transducer is provided with resistive load characteristics or near-resistive load characteristics, and is provided with ultra-high sensitivity, high resolution, and high-fidelity quality. |
