    • A body-acoustic device is provided which comprises a housing (1), a diaphragm (4) dividing an inner space of the housing into a first chamber (5) and a second chamber (6), and a loudspeaker (7) mounted to an opening provided in the diaphragm, wherein the diaphragm is made of a transversely vibratory member and/or has a perimetric edge supported by an inner surface of the housing via an elastic member (10), and wherein the diaphragm (4) is further provided with a port (9) for air movement between the first and second chambers (5), (6). When the loudspeaker (7) is operated, the diaphragm vibrates with a cone paper (8) to generate sufficient heavy bass sound with high sound clarity as if the diameter of the loudspeaker had increased. The port provided in the vibrating diaphragm facilitates the vibration of the diaphragm, further increasesing the sound pressure created by the diaphragm vibration due a sound throttling effect caused by the port. As a result, sufficient and clear body-felt sound, especially heavy bass sound, can be obtained through vibration of the housing outer walls.
