We require a small loudspeaker to deliver vibrations in the 100-300Hz range to mouse whiskers. We are currently using a Visatron Rectangular Speaker Driver , which has a convenient flat surface, but is producing harmonic artefacts that will be easily audible to the mouse.
Does anyone have a favourite small loudspeaker than performs well in the low frequency range?
Thanks,
Kerry
