Microphones!
- What Is a microphone?
- A microphone is a devise which generates electricity from sound waves
- A microphone is a devise which generates electricity from sound waves
- How do microphones work?
- The microphone produces a small induced voltage in a coil of wire when sound waves hit a diaphra.m
- It is simelar to a loud speaker in reverse with a diaphram instead of a paper cone
- This type of microphone is called a moving coil mircophone
- This type of microphone is called a moving coil mircophone
- It is simelar to a loud speaker in reverse with a diaphram instead of a paper cone
- The microphone produces a small induced voltage in a coil of wire when sound waves hit a diaphra.m
- What happens?
- the waves strike the diaphragm and move it backwards and forwards ate the same frequency as the sound
- The moving diaphragm moves the coil backward and forward
- this induces a changing current at the same frequency as the sound
- this changing current called a signal, can be used for recording tot the signal can be sent to a amplifier which makes the signal big enough to drive loudspeakers
- The loudspeaker converts the signal back into the original sound
