Abstract
A constant beamwidth loudspeaker A constant beamwidth loudspeaker having a plurality of transducer units/drivers. The transducers are combined in series and parallel for approximating a constant beam-width/directivity without attenuating any of the transducers with resistor components. The transducers are arranged on a circular arc.
Claims15
A transducer system for outputting sound in a radiation pattern having a substantially constant directivity across a frequency range, the transducer system comprising:
- an input;
- and
- a plurality of transducer units, each transducer unit connected to the input for receiving an electric signal and converting the electric signal to sound,
- the plurality of transducer units arranged on a curve, the curve having a finite radius,
- the plurality of transducer units comprising at least a first transducer unit, a second transducer unit, and a third transducer unit, and
- each transducer unit of the plurality of transducer units connected to the input substantially unattenuated.
