An "amplifier" adds energy and a soundboard definitely does not do that..... A "transducer" changes energy from one form to another and a soundboard doesn't do that either since vibration/oscillate is inherent in both the string and the soundboard. It is a 'transmitter' though according to the definition;, i.e. "To convey (force or energy) from one part of a mechanism to another." But then merely transmitting that energy doesn't explain what the principle behind the strings almost inaudible sound being made immently audible through linkage with the soundboard is without the air present.....so I guess it really isn't a transmitter either ... :-( How bout we consider the soundboard to be a 'amptranmitter'...you know a functional applicance that contains no totality of any of the three but performs large segments of them all? :-) Just a rather weak thought.
