> Do you think it would be possible to use a piezo transducer as a speaker,= and run the output of the Sony through an amplifier to drive it? That migh= t get around the 30kHz dip in the Sony's speaker, but still result in a rea= sonably inexpensive solution. Hi Tom, I would first try common earphones or headphones. It is unlikely that they= also have a dip at exactly 30.0 kHz. I think this is what Peter already wa= nted to do. I see no big advantage in using a piezo transducer for this purpose. Their= frequency response is also far from perfect - there are usually numerous d= ips and peaks as well... Regards, Raimund |
