Made me laugh... so was worth a Thanks. Then I decided to remove such an unnecessary Thanks.
Aside from the
very prominent resonant frequency of the fork itself, by what mechanism would the tuning fork be excited by? Would not some manor of mechanical, or electrical device need to be coupled to the fork to cause it to vibrate? If so, would it not be simpler to just use something that already directly converts electrical energy into mechanical/acoustical energy (i.e. a typical speaker driver)?
