ELECTROMECHANICAL-ELECTROACOUSTIC TRANSDUCER WITH SMALL THICKNESS AND WIDE RANGE OF MOTION AND RELATING METHOD OF PRODUCTION Russian patent published in 2016 - IPC H04R9/02 

Abstract RU 2593681 C2

FIELD: electromechanics.

SUBSTANCE: invention relates to electromechanical electroacoustic transducers. Summary: converter (1) comprises ring-shaped magnetic assembly (3), which generates magnetic field, elastic suspension (4) connected to magnetic assembly, support (8) connected to elastic suspension, and retaining coil (6), which can move in magnetic field induced by magnetic assembly, and acoustic membrane (5) connected to support (8) of coil for vibration and sound emission. Magnetic assembly (3) comprises thin holding and support structure (7) made of non-ferromagnetic material, and plurality of magnets (30) with magnetic axis (A) and axial anisotropy, wherein said magnets (30) are located side by side to each other inside said thin holding and support structure (7), which operates as support structure for converter and as housing structure for magnets.

EFFECT: technical result is possibility of obtaining transducers with larger diameter, decreased thickness and wide range of movement.
