| 摘要 |
The invention relates to a loudspeaker comprising at least one magnet ( 5 ), a membrane ( 2 ) with an outer edge ( 32 ) defining an outer edge plane ( 30 ) of the membrane, a bead ( 3 ) surrounding the membrane ( 2 ), a moving coil ( 9 ) which is fixed to the first membrane ( 2 ), and a magnet system ( 4 ) comprising at least one magnet ( 9 ). Said loudspeaker also has a supporting structure ( 1 ) for receiving the magnet system ( 4 ) and the membrane, the membrane being connected to the supporting structure by means of the bead, and the supporting structure has a front side which is oriented towards the membrane and a rear side which is oriented in the opposite direction. Said membrane ( 2 ) is at least partially convex towards the front, in the predominant acoustic direction ( 33 ), and the region ( 28 ) of the membrane ( 2 ), to which the moving coil is fixed, is arranged in front of the outer edge plane ( 30 ) of the membrane. The diameter (D) of the membrane ( 2 ) is larger than the diameter of the moving coil (d) which moves the membrane ( 2 ).
