Abstract
Perfections introduced into an earphone preferably provided with an annular joint thickening which in the position of use is applied to the ear or surrounds the ear, made of soft and capable of yielding material, possibly elastic, whose sealing ring, the the earpiece closes a wide space towards the outside a space of coupling between the membrane operated by the electroacoustic converter and the ear inlet, characterized in that the coupling space has one or more openings in which passive membranes are installed capable of vibrating with resonance. Own defined, and the openings are associated with sound paths that lead to the outside, to the back side of the active membrane of the converter or to acoustically effective cavities.
