ABSTRACT:
The loudspeaker and enclosure are provided with aerodynamically-shaped passages providing low-pressure regions for inducing flows of air into and about the driver motor of the loudspeaker in response to vibratory movement of the speaker cone. An aerodynamically-shaped body is disposed within the pole piece to define a venturi passage for exchange of air between an interior chamber defined by a coil former and the back of the speaker. Aerodynamically-shaped openings are provided through the pole piece for inducing flow of air about the voice coil in the voice coil gap between the pole piece and permanent magnet. The speaker frame support is provided with aerodynamically-shaped openings to induce air flow into the interior chamber. In this manner, low-pressure regions established by the aerodynamic shapes induce flow of cooling air about the voice coil and pole piece in response to vibratory movement of the cone. Aerodynamic shapes are disposed in the intake and exhaust vents of the speaker enclosure to exchange air between the enclosure and atmosphere in response to vibratory movement of the speaker.
