| 描述： | This is a recording I made of a 12volt relay wired to a function generator. This causes the metal plate to vibrate, buzzing against the metal contacts. I swept the frequency up and down, I think through a couple of hertz to about 120. Anything higher than that did not supply the power to drive the coil (the generator was only rated to 10 volts peaktopeak.) Furthermore, the relay is sitting on the metal case of the generator, acting as a soundboard and amplifying the buzz for the microphone only a few inches away. |
