Abstract
An electrodynamic sound transducer having a transducer basket, a flexible membrane and a magnetic system having an air gap, a voice coil on a cylindrical coil carrier and a dampening central element, which is connected to the membrane, includes a coil carrier of the voice coil is connected to the membrane by a mounting adapter. The membrane is configured as a three-dimensional free-form surface except for conical shapes.
Claims27
An electrodynamic sound transducer, having:
- a transducer basket having at least one air passage,
- a flexible membrane,
- a magnetic system having a magnet, a magnetic back-iron, a pole plate, and an air gap between the pole plate and the magnetic back-iron of the magnet,
- a voice coil on a substantially cylindrical coil carrier, which dips into the air gap and which is connected to the membrane for generating sound, and
- a damping central element, which is connected to the membrane,
- wherein
- the coil carrier of the voice coil is connected to the membrane by a mounting adapter,
- the membrane is configured as a three-dimensional free-form surface except for conical shapes,
- the mounting adapter at the voice coil side is complementary in shape to the coil carrier of the voice coil and at the membrane side it is complementary in shape to the free-form surface of the membrane,
- the mounting adapter is configured without steps in the area between the coil carrier of the voice coil and the membrane,
- the pole plate of the magnetic system is connected centrally and directly through the central element to the free-form surface of the membrane,
- and a damper layer is arranged in a marginal region between the membrane and the transducer basket.
