Abstract
A loudspeaker enclosure is shaped as a truncated pyramid with all vertical edges being smoothly rounded. A high-frequency speaker is mounted in an individual spherical shell and affixed to the top of the truncated pyramid. Other speakers are mounted inside the enclosure, and the portion of enclosure adjacent the speaker in a horizontal plane is kept to a minimum to reduce standing waves. An individual sound chamber is provided for each speaker mounted inside the enclosure. The speakers are also mounted with vibration isolation mounts which vibrationally decouple the speakers from the enclosure.
Claims12
A loudspeaker enclosure and loudspeaker in combination, comprising:
- a hollow closed structure formed as a truncated pyramid having vertical edges smoothly rounded, and having one side with an aperture formed therein, and
- a loudspeaker arranged internal to said hollow closed structure and mounted on said one side of said truncated pyramid for radiating sound through said aperture in said one side,
- said loudspeaker having a center, and said one side of said truncated pyramid and said loudspeaker having a dimensional relationship therebetween so that a horizontal plane passing through said center of said loudspeaker passes through a section of said one side of said truncated pyramid, said section being smaller in length than the wavelengths of the sounds to be radiated by said loudspeaker.
A loudspeaker and enclosure combination, comprising:
- a hollow closed truncated pyramidal elongate structure which is taller than it is wide, and having one side with first and second apertures formed therein,
- a spherical shell affixed on the truncated surface of said structure,
- a first loudspeaker enclosed by said spherical shell for radiating high-frequency sounds, and
- second and third loudspeakers arranged inside said elongate structure for radiating sounds through said first and second apertures, respectively,
- said third loudspeaker being adapted for producing sounds having long wavelengths and being located towards the bottom of said structure, and wherein a portion of said one side of said structure lying in a horizontal plane passing through the center of said third loudspeaker on either side of said third loudspeaker has a length in said horizontal plane which is less than the wavelength of the sounds produced by said third loudspeaker,
- said second loudspeaker being adapted for producing sounds in the middle of the audible spectrum and being located between said first and third loudspeakers on said one side of said structure, and wherein a portion of said one side of said structure in a further horizontal plane passing through the center of said second loudspeaker on either side of said second loudspeaker has a length in said horizontal plane which is less than the wavelength of the sound produced by said second loudspeaker.
