  • Patent number: 8284983
    Abstract: A coaxial loudspeaker including a tweeter unit and a low/midrange unit with a cone diaphragm suspended in a loudspeaker basket, which comprises an electromagnetic drive fixedly attached to a loudspeaker basket on its tapered end, in the area of which the tweeter unit is positioned, whose sound radiation surface is directed away from this drive. In one embodiment, in order to suppress the sound focusing of traditional coaxial loudspeakers with a woofer/midrange cone diaphragm, and to ensure a simple and cost-efficient assembly of the tweeter unit, the electromagnetic drive for the cone diaphragm of the woofer/midrange unit is located within the space bordering the convex curved exterior side of the cone diaphragm, and the tweeter unit is positioned outside of this space.
