<p>An enclosure (10) for a loudspeaker (26) has a housing (14) formed of sound reflecting material having an opening (24) dimensioned for mounting of the loudspeaker (26) therein. A body (32) of sound deadening material is disposed within the housing (14). The body (32) of sound deadening material defines a bell-shaped chamber (30) having a top and a bottom (36). The top (24) of the bell-shaped chamber (30) is located at the loudspeaker opening (24) and the bottom (36) of the bell-shaped enclosure (30) is remote from the loudspeaker opening (24). The enclosure (10) is preferably used in combination with a novel sinusoidal waveform energy reflector (12). The reflector (12) has first and second surfaces (52 and 54) each having an exponential cross-section and being reflective to the waveform energy. The first surface (52) terminates in an apex (56) pointing at a source (26) of the waveform energy, such as a loudspeaker (26). The second surface (54) intersects the first surface (52) around a perimeter (58) of the first surface (52). The loudspeaker enclosure (10) produces sinusoidal sound waves more accurately and with less speaker fatigue, and the exponential reflector (12) reflects those sound waves more accurately than in the prior art.</p> |
