“Take a powerful DC amplifier, connect it to a large woofer, feed the system with a signal generator, and at the end, just add milkshake. Of course it is also possible to measure the g-force of the shaking”photos & video.

  1. It looks like that, but it is only a sync problem between the framerate of the camera and the “high” frequency shaking. It is a DC system, so it could handle it. The speaker might get hot and burn, but anyway, adding a low frequency could maybe change the quality and taste of the finished milkshake ;-)

  2. He’s right. the apparent super low frequency is due to the said sync problem. The system works down to 0Hz, but the practical use for frequencies below 1 Hz is limited because you the q-force is limited by the stroke length of the speaker.
