    Abstract: A line array loudspeaker system including a large number of small, regularly and closely spaced acoustical drivers. Each of the acoustical drivers receives essentially the same audio signal. In another embodiment, a line array includes a plurality of portable line array modules that are constructed and arranged to be attached end to end to form a longer line array.

    Abstract: A method and apparatus for determining the directivity index (DI) and directivity factor (Q) of a loudspeaker is described. A microphone is placed in the throat of a horn-type loudspeaker to measure the acoustical pressure at this point. A second microphone is placed along an extension of a central axis of a loudspeaker at a predetermined distance from the mouth of the loudspeaker to measure the acoustical pressure at this point. The output of each of the microphones is rectified and converted to decibel form. The decibel signal representing acoustical pressure at the throat is subtracted from the signal representing the measured pressure at the predetermined distance. A signal (in decibel form) representing the distance of the second microphone from the mouth of the horn is added to the difference signal and a signal (in decibel form) in accordance with the diameter of the loudspeaker throat is subtracted from the difference signal to provide a signal in accordance with directivity index. From the directivity index a signal in accordance with directivity factor (Q), which is a power ratio, can be derived.

    Abstract: The coil form for a loudspeaker voice coil is made of a material having high thermal conductivity. The coil form is attached to or integrally formed with a highly thermally conductive spider member which resiliently supports the coil form on the frame structure of the speaker, which also has high thermal conductivity. In one embodiment of the invention a heat sink member to facilitate the dissipation of the thermal energy is attached to the speaker frame structure. In an embodiment involving a horn type speaker, the horn element, which is made of a thermally conductive material, is attached to the speaker frame and also functions as a heat dissipator. In this manner, the likelihood of overheating of the speaker voice coil is greatly diminished.
