The Loudspeaker Unit contains an 87mm diameter 12W, 8 Ohm Mylar (waterproof) loudspeaker, with 4mm input sockets. The speaker cone is fully exposed which allows it to be used for a range of experiments apart from its normal use as a loudspeaker, for example:• Comparing different waveform inputs at low frequencies from a signal generator• Observing the motion of small polystyrene beads on the speaker cone at different frequencies – this can then introduce the kinetic theory of gases• Adding a small piece of sponge or foam to polystyrene beads allows demonstration of Brownian Motion• A thixotropic mixture can be poured onto the cone and standing waves observed (also works with coloured water)
