Description
Purpose
The speaker is utilized in demonstration experiments as a source of sound waves. The speaker is recommended to use in couple with functional generator (low frequency generator). The speaker is also utililzed in experiments on alternative current properties and electromagnetic oscillation studies which are based on the "Electricity 3" demonstration set.

Conctruction and work order
The speaker is implemented as dynamic head mounted at plastic foundation of 100 mm x 100 mm sizes by means of metal rods so that the run-out lies in vertical plane. High quality of sound of the whole frequency range is provided with structural features of moving dynamic head system. The speaker is pluuged to generator or circuit by means of multipurpose clamps put on the upper surface of plastic foundation. Do not plug -n or plug-out the speaker when the circuit power is the greatest!
