PURPOSE: A sound bodily sensed system is provided to transfer an electrical sound signal to a human body by converting the electrical sound signal to mechanical vibration. CONSTITUTION: An upper cylindrical member(11) is formed on an inner circumference of an upper cover(10). A lower cylindrical member(12) is formed on an inner circumference of a lower cover(14). An upper voice coil(16a) and a lower voice coil(16b) are wound around the upper cylindrical member(11) and the lower cylindrical member(12), respectively. A pole(15) is inserted into the upper and the lower cylindrical members(11,12) and fixed to the upper and the lower covers(10,14). A plurality of vibration bodies(21,22,23,24,26) are vibrated by a variation of magnetic field around the upper and the lower voice coils(16a,16b). The upper cover has a screw hole(10c) which is formed at a center of an edge portion(10e) and the upper cylindrical member(11). The lower cover(14) is formed with a body portion(14a) and a circumference portion(14b). The body portion(14a) has a screw hole(14c) and a flange(14d). The screw portion(14c) is formed at a center of the lower cylindrical member(12). An edge portion(14e) and a damper spring(25) are inserted into the flange(14d). The circumference portion(14b) has a combination groove(14g). The pole(15) has a screw hole(15c). A vibrating body is formed with the vibration bodies(21,22,23,24,26) including a doughnut-shaped magnet(21), an upper yoke(22), a lower yoke(23), an upper damper(24), and a lower damper(26).
