Automotive Speaker Emulates Relay Sounds

In addition to chimes and the ability to produce multiple tones, the SAA-30A automotive speaker can produce a unique "tick-tock" sound associated with the mechanical relay sound heard when a vehicle's direction indicator is activated. The device can also produce a logic-driven chime that can act as a warning that the auto's lights have been left on.
