Abstract (en)
[origin: WO2019166705A1] The invention relates to a powerful, but compact, vibroacoustic device which is capable of transmitting a large portion of the musical sound spectrum without emitting a loud output volume so as not to disturb individuals nearby. The invention relates to a vibroacoustic device comprising a permanent magnet (101) generating a permanent magnetic field in a space (102) known as an air gap, and a coil (103) of electrically conductive wire arranged in said air gap in the axial direction (X-X) and provided with two electrical terminals, the coil (103) being rigidly connected to a plate (104) onto which a rod (105) is attached which is capped by a disk (106) covered with a layer of elastomer (107-108) and intended to rest on the chest of a user during use.
