Patent ID: 7286681

Claim:
A broadband speaker, not a cone speaker, embodied as an electrodynamic sound converter, comprising at least 1.1 one first magnet ( 5 ), 1.2 one first membrane ( 2 ) with one membrane outer edge ( 32 ) that spans a membrane outer edge plane ( 30 ), 1.3 a first crimp ( 3 ) running around the circumference of the first membrane ( 2 ) for the flexible mounting for the first membrane ( 2 ), with the crimp being composed of a different material than the first membrane, 1.4 a first vibration coil ( 9 ) that is directly or indirectly attached to the first membrane ( 2 ), and 1.5 a magnet system ( 4 ) with at least one first magnet ( 5 ) and at least one first annular gap into which the first vibration coil protrudes and furthermore 1.6 a carrying construction (basket) ( 1 ) for housing the first magnet system ( 4 ) and the first membrane, with the first membrane being connected to the carrying construction by way of the first crimp and with the carrying construction having a front side oriented toward the membrane and a rear side oriented in the opposite direction, characterized in that 1.7 the first membrane ( 2 ) is constructed in one piece and at least partially toward the front in the direction of the preferred direction of the sound, in that said membrane has an arc, and in that the region ( 28 ) of the first membrane ( 2 ) to which the first vibration coil is attached, is disposed in front of the plane ( 30 ) of the outer edge of the membrane, with 1.8 the first membrane ( 2 ) having a diameter (D) that is greater than the diameter of the first vibration coil (d) that moves this membrane, 1.9 the first annular gap ( 8 ) having a narrowed parallel region in the direction of the membrane, and 1.10 the magnet system being disposed exclusively in front of the carrying construction (basket) ( 1 ).
