Electrodynamic acoustic transducer with unique magnet system
A recently granted patent (Publication Number: US11889284B2) discloses an Electrodynamic acoustic transducer featuring a unique design with a frame or housing, a membrane, and a magnet system comprising center magnets with different magnetic orientations, center top plates, and a common bottom plate. The coil arrangement includes multiple voice coils attached to the membrane and movably arranged relative to the magnet system. The magnet system generates a magnetic field transverse to the conductors of the voice coils, enhancing the transducer's performance. Additionally, the outer magnet circuit region of the transducer includes elongations of the bottom plate, side plates, or outer magnets with outer top plates, further optimizing its functionality.
Furthermore, the patent claims detail various aspects of the electrodynamic acoustic transducer, such as the arrangement of center magnets in a matrix-style, the shape of the center magnets as circular segments, and the distribution of magnetic flux, force factor, mass, and centers of gravity in a symmetric manner. The patent also highlights specific ratios and dimensions of the magnet system, voice coils made of metal foils, and the control circuit connected to the coil arrangement in an electroacoustic system. By focusing on intricate design elements and functional features, the patent aims to protect the innovative technology and unique configurations of the electrodynamic acoustic transducer, offering potential advancements in the field of audio technology and sound reproduction systems.
