ABSTRACT:
The present invention is directed to a diaphragmatic (planar) electroacoustic transducer that forms a complete sound radiating transducer and provides high efficiency and linearity. The diaphragm is easily exchangeable and rectangular in shape, and may be made of very thin polyamide film with a plurality of aluminum conductors formed on one side of the diaphragm. The plurality of conductors form two identical and symmetrical coils such that conductors of each coil are interlaced. The two sections of the coils are disposed in dense air-gaps of the magnet system, which comprises a plurality of high (BHmax) Neodymium magnets. The binary interlaced coils can be utilized in a number of modes, for the purpose of accomplishing a variety of operating modes.
