Abstract
Improvements in the electroacoustic motors for microphones, loudspeakers and headphones, characterized in that the freedom of oscillation of the vibrating element is established by a perimeter crown constituted by a plurality of grooved folds, arranged tangentially to the inner circle and endowed with a high flexibility, which improves the axial suspension of the inner main vibrating zone, particularly in the high frequency zones.
