Abstract

L'invention propose un dispositif vibroacoustique puissant, mais peu encombrant, capable de transmettre une grande partie du spectre sonore de la musique, et sans émettre un volume sonore important vers l'extérieur pour ne pas déranger les personnes alentour. L'invention propose un dispositif vibroacoustique comprenant un aimant permanent (101) générant un champ magnétique permanent dans un espace (102) appelé entrefer, et une bobine (103) de fil conducteur d'électricité agencée dans cet entrefer dans le sens axial (X-X) et munie de deux bornes électriques, la bobine (103) étant solidaire d'une plaque (104) sur laquelle est fixé une tige (105) surmontée d'un disque (106) recouvert d'une couche d'élastomère (107-108) destinée, en utilisation, à être en appui contre le thorax d'un utilisateurThe invention provides a powerful vibroacoustic device, but not very bulky, capable of transmitting a large part of the sound spectrum of music, and without emitting a large sound volume to the outside so as not to disturb the people around. The invention proposes a vibroacoustic device comprising a permanent magnet (101) generating a permanent magnetic field in a space (102) called an air gap, and a coil (103) of electrically conductive wire arranged in this air gap in the axial direction (XX ) and provided with two electrical terminals, the coil (103) being integral with a plate (104) on which is fixed a rod (105) surmounted by a disc (106) covered with a layer of elastomer (107- 108) intended, in use, to rest against the thorax of a user
