  • SLOTTED WAVEGUIDE FOR LOUDSPEAKERS
    Publication number: 20120121118
    Abstract: A slotted waveguide for use with an electrodynamic transducer is described. The slotted waveguide has a transducer front surface for radiating acoustic energy from the electrodynamic transducer. The transducer front surface is concave and the electrodynamic transducer is operable to a desired high frequency. The slotted waveguide may include a body and a volume displacement element. The slotted opening has a width not substantially greater than a wavelength corresponding to the desired high frequency and the volume displacement element has a displacement surface that extends inward into the electrodynamic transducer and complements in shape the transducer front surface.
