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.
Claims11
A coaxial loudspeaker, comprising:
- a first frequency generating unit including a cone diaphragm suspended in a loudspeaker basket, and an electromagnetic drive disposed at a tapered end of the cone diaphragm;
- a second frequency generating unit having a sound emitting surface, the second frequency generating unit being fixed to the loudspeaker basket with its sound emitting surface facing away from the electromagnetic drive;
- the electromagnetic drive being disposed within a space surrounded by the convexly curved outer side of the cone diaphragm;
- the second frequency generating unit being disposed outside the space;
- and
- wherein the first frequency generating unit is configured to emit sound through an open region between bracing struts of the loudspeaker basket in a direction away from the electromagnetic drive.
