  • Patent number: 4496021
    Abstract: A radial high-frequency, high-efficiency orthospectral loudspeaker is disclosed in which a horn-loaded, electro-acoustic driver is used and the horn configuration is radial and annular to give a lateral dispersion of the sound generated by the loudspeaker, the output being frequency and amplitude equalized over the desired high frequency band.

  • Patent number: 4348549
    Abstract: A loudspeaker system for radiating acoustic output throughout in generally horizontal planes, comprising an enclosure having low frequency (woofer) and high frequency (tweeter) radiators mounted in spaced relation on a common vertical axis. The horn loaded compression driver tweeter is the upper of the two and has a diaphragm radiating axially upwardly into a flaring horn, preferably exponential, including an intermediate annular section which abruptly reflects sound waves approximately into a radial outlet section of the horn radiating approximately horizontally through, providing the known advantages of horn loaded compression drivers in a radically more compact form than conventional horn speakers. The woofer radiates axially downwardly, and a conical plug spaced downwardly from the speaker cone serves to load the cone for higher efficiency and smoother response, and to deflect acoustic output of the cone generally horizontally through in a 2.pi.
