Abstract
A loudspeaker device includes an enclosure, a loudspeaker unit and a passive radiator both mounted to the enclosure. The passive radiator includes an edge sandwiched and bonded between a first diaphragm and a second diaphragm. This structure allows increasing the bonding strength between the edge and the first diaphragm as well as between the edge and the second diaphragm, so that the loudspeaker device can withstand greater maximum inputs and reproduce quality bass sound.
