How microphone works.Function of microphone.Types of microphone.Definition of microphone in simple words.

Definition: Audio Systems is the most usable topic in the electronics.It is a part of our life.mostly we are used that devices like speakers,mikes etc.

     Mike is a transducer.it is identify a sound signals.and that is created the image of this sound. Sometimes,in the electronic devices there is a need for instruments that thansforms sound waves into electric signals.


     Sometimes,there is a need for instruments that transforms electric signals into sound waves.

The base of Microphone: Microphone is a simply just a converter.which is convert sound waves into electric signals.this electric change is in a A.F. range.and which is amplify in audio amplifier and we can listen by a sound.
     Convert sound waves in to electric signals that device called microphone.it is simply called a mike.

Types of Microphone: Various types of microphones available in the market. High volumes, low valumes,light,heavy,small and big type,low range,high range.various types of mikes are available and their uses, that can choice and buy a different mike.see below,

1. Electrodynamic Microphone: In this microphone, To use a one strong magnet in U Type.its simply designs to a poll peace on the magnets centre area to a stand.

     To fitted a coil out of this poll peace in a easily moving condition. And spakers curtain is gently stick in coil.
     Coils two terminals is to out for mikes output terminal. Its a simply design a electrodynamic microphone.

2. Carbon Microphone: In this microphone, to paste a small grain of carbons  in a bin.
     The pressure on this carbon grains makes a difference in its resistance.use this technic to build a carbon microphone.

3. Crystal Microphone: To create a crysral microphone uses two natural crystals.like,Rochelle salt and biemarf. this crystalline substance has two accesses.mechanical access and electric access.
     Crystal mike is work on pizzo electric effect.

4. Condenser Microphone: In this microphone,there are two plates are face to face connected.between two plates use a resistor.one air condenser and one battery to be connected in plates.and two plates front side to stay a Diaphragm.its a simple design of a condenser microphone.
     condenser mike works on a variable capacitance technic method.

5. Cordless Microphone: It is very usefull to us.it is a small size F.M. transmitter. its transmission range is very good and that is a very huge and clearly.
     The cordless mic has an F.M.transmitter,then the amplifier has an F.M.receiver. It is works from the amplifier within 10 to 20 mtr distance.
     Cordless mic works on the F.M.transmissions method.

6. Ribbon or velocity Microphone: In this microphone,there are use a one U type strong magnet,one alluminium ribbon and one step up transformer. the alluminium ribbon fitted in magnets centre and south-north pole.
     The robons output terminals connected to the transformers input terminal.
