One is the hydrophone, used to pick up sound waves underwater.
microphone............
This is an electronic device which converts electrical signal into a digital signal.
A transducer (trans = across, duce = to lead) is a device that converts one form of energy into another. A microphone converts sound waves into electrical signals. Others would be accelerometers, loudspeakers. An oscillator on the other hand, generates a signal without there being an input signal. These are two different things.
Pressure transmitters function by measuring the amount of pressure that is exerted on their sensors. It measures mechanical pressure and converts it to electrical signal.
A computer converts signal into an image.
Microphone can do this job.
A microphone.
A microphone is an acoustic-to-electric transduceror sensor that converts sound into an electrical signal.
The diaphragm
-- microphone -- piezoelectric crystal -- dynamo
In the microphone, there is a diaphragm, which converts the DJ's voice into an electrical signal. This signal is sent along the wire to the antenna, which broadcasts it into the ether. Your home radio receives the signal through its aerial, then converts the signal from an electrical signal to audio - which is detected by your ear.
microphone............
Teh varying pressure of the air (the sound) causes a varying electric potential in microphones. There are various techniques, one is called "dynamic microphone" whereby a membrane with a coil is allowed to move inside a magnetic field. The sound moves the membrane, the movement of the coil inside the magnetic field generates a current in the wire which is the signal. Ten kinds of microphone are discussed on Wikipedia (see Related link below)
A microphone is a transducer, that converts sound pressure waves into a varying electric signal. It can then be used to amplify, record or transmit sound to various other devices.
The transducer converts the non-electrical variable to some sort of electrical signal.An appropriately calibrated measurement device converts the electrical signal to a displayed value corresponding to the original variable's current value.
A microphone is a transducer of energy from one form to another. It takes sound waves or acoustic energy and then converts it into an audio signal or electrical energy. A microphone is used is speaking appearances to amplify what someone is trying to say to a large crowd.
