Whistle
middle of the night or even subdue hostile dogs. It
emits sound in the ultrasonic range, which people
cannot hear but other animals can, including dogs
and domestic cats, and is used in their training.
Allows you to use a cheap loudspeaker as a 210
microphone. Sound waves reaching the speaker
cone cause fluctuations in the voice coil & converted
into electrical signal.
Two separate boxes are connected by a thin 485
screened cable having the length desired to speech
together.
