360 Degree Dispersion Frequency Invariant Acoustic Transduction System
An acoustic transduction system has been designed which couples the sound field of two transducers in phase and produces a resultant acoustic radiation pattern which has a full 360 degree horizontal by 90+ degree vertical frequency invariant beamwidth. The system incorporates an acoustic lens, rather than a phased array or electronic technique, to couple the sound fields and produce the wide dispersion. The system is used in a loudspeaker to achieve a 360 degree sound field which is devoid of high frequency beam collapse, and combing.
