==== Proximity Sensor ==== | |||
From the PorchBoard website: | |||
:Our patented passive proximity sensor system creates an analog, clean bass beat without the common low-end amplification problems of noise, feedback or delay. | |||
Added notes from Bill | |||
:Microphones and piezo pickups make use of a resonant surface, leading to noise and feedback, especially when amplifying low-end. Regular guitar pickups are wide range and not tuned to a specific frequency | |||
==== Background ==== | |||
From his prior work in the automobile industry, Bill was familiar with electrically tuning a magnetic sensor for specific applications. This was the basis for our 'proximity sensor system', which uses a tuned, magnetic sensor that is capable of producing a very low dominate pitch when approached by a ferrous transducer plate. | From his prior work in the automobile industry, Bill was familiar with electrically tuning a magnetic sensor for specific applications.
