TECHNIQUES FOR ANALYZING CONNECTIVITY WITHIN AN AUDIO TRANSDUCER ARRAY

An array of audio transducers includes an optical emitter, for example, and without limitation, a light emitting diode (LED), associated with each transducer. Simultaneous stimulation of all transducers illuminates all LED's. An imager then creates a map of the transducer array. Stimulation of a single transducer, illuminating the associated LED, creates an optical signature that imaging software uses to determine the position of the transducer within the array. The system then verifies the correspondence between each transducer and the associated driver amplifier by sequential stimulation of each transducer within the array. The system may vary the frequency of the stimulation applied to transducers that include filtering networks, known as crossovers, to validate performance. Further, the system may compute the angles between transducer assemblies that may be deployed in non-planar configurations, thus ensuring that the installation is constructed to specifications. 1.
