ABSTRACT:
A phase plug structure is described which is an intermediate element between a conventional fiber cone loudspeaker and an exponential horn. The purpose of the phase plug is to equalize acoustical path lengths and thereby minimize high-frequency cancellations caused by phase differences. The design of the phase plug is based upon an analysis of both low-frequency and high-frequency horn behavior. A usable bandwidth of four octaves is obtained over a sharply-defined angle of radiation.
In accordance with another embodiment of the invention, an enclosure is provided having a first exponential radiator, of relatively small size attached to the front of the speaker, and a relatively large exponential radiator coupled to the rear surface of the speaker for improved base response.
