Vibra-massage unit comprising a resonating structure (1) with ergonomic shape in contact with a sound transducer (20) suitable for transmitting to it a plurality of vibrations and for propagating sound waves generated by an audio signals generator (10) after suitable amplification. The resonating structure (1) comprises essentially a central beam (2), for example curvilinear, and a plurality of rods, or boards (3), arranged transversally to it. The vibrations depart from the transducer (20) jointly for then propagating through the resonating structure (1) in a differentiated way, selectively concentrating according to their frequency and their amplitude in determined Vibra-massage unit comprising a resonating structure (1) with ergonomic shape in contact with a sound transducer (20) suitable for transmitting to it a plurality of vibrations and for propagating sound waves generated by an audio signals generator (10) after suitable amplification. The resonating structure (1) comprises essentially a central beam (2), for example curvilinear, and a plurality of rods, or boards (3), arranged transversally to it. In particular, the resonating structure can be solid, hollow, or pneumatic and can be made of material capable of conducting vibrations, for example wood, metal, glass, plastic material or conglomerated material. The vibrations depart from the transducer (20) jointly for then propagating through the resonating structure (1) in a differentiated way, selectively concentrating according to their frequency and their amplitude in determined areas of the resonating structure (1). In particular, on the resonating structure (1) it is possible to identify at least one zone (7) where the vibrations are concentrated at lower frequency and at least one zone (5) where the vibrations are concentrated at an intermediate frequency.
