Would it be possible to design the device to detect if the speaker has been tampered with? Perhaps having some sort of microphone on board to detect whether the

  This could be put into the speaker driver, to do something like an impedance measurement, to verify that something that looks like a speaker coil is still present. If you wanted to make something hard to defeat, you could measure the capacitance between the coil and case, as a deflection measumerent, to verify that coil was actually moving in a way that it should be. Both would probably add a relatively large amount of power consumption, completely change the design, and add a bunch of cost, where nobody would be interested anymore.
