Definition: A transducer is a device that converts one form of energy â typically a signal â into another. Example: A speaker is a type of transducer that converts electrical energy (the audio signal) into mechanical energy (vibration of the speaker cone/diaphragm).
A transducer is a device that sends out sound waves which bounce off targets such as fish or lake bottoms. When the signal is ... read more reflected back to the transducer, images are formed. It also determines depth by measuring the time it takes for the sound wave to return back to the device. There are many types of transducers, but they all work off the same principle.
