Patent ID: 10506350

Abstract:
An electroacoustic transducer for generating an audible acoustic signal includes a base, a cathode having a plurality of cathode discharge elements arranged into an array of cathode discharge elements disposed around an axis associated with the cathode and mounted on the base, and an anode having a plurality of anode discharge elements arranged into an array of anode discharge elements disposed around an axis associated with the anode and mounted on the base. An inter-electrode space separates the cathode and the anode. A first circuit portion connects the cathode to a voltage source, and a second circuit portion connects the anode to the voltage source. The cathode and anode discharge elements extend from the base toward the inter-electrode space. Respective arrays of the cathode and anode are opposite of each other with respect to the inter-electrode space and axisymmetric such that the cathode axis is aligned with the anode axis.
