Sounder. This element generates a sound when current runs through it. Place up to three sounders in the simulation window. With the Select tool, you can move and rotate sounders, and wire them to other objects. You attach wires to the resistor's two nodes, which are indicated by the yellow rectangles in Figures 1 and 2.

The sounder makes noise when 1.0 or more volts are applied across its nodes. The sound that it makes depends on the voltage applied.
