Circuit diagram of an electret condenser microphone Structure Of An Electret Capsule An estimated 700–800 million electret microphones are produced worldwide every year with around 80–90 per cent of all microphones manufactured relying on the electret principle. Indeed, small systems, such as clipon microphones, could hardly be produced any other way. Applications Condenser microphones are preferred for the recording of music (among other applications) because of the Most small personal microphones within the Sony, Sanken, Sennheiser and Beyer ranges are, in fact, capacitor microphones, but are the electret type.

The highlevel output gives Electret designs A much later development was the socalled 'electret' or 'electret condenser' principle. The need to polarise rigid back plate instead. Topquality examples of back electrets are therefore just as good as conventional capacitor mics with their 48 volts of polarising voltage.As one can imagine, the displacement of the capacitor plate is so small that the resulting variation in voltage requires amplifying before it leaves the microphone. As such, condenser microphones have amplifier circuits built in, and these require a voltage to power the

Some microphones of a single capsule, solid state condenser design utilize an electret capacitor, so that the diaphragm is permanently Fig.The vibration sensitivity will thus be the same for electret microphones as for metal diaphragm types; the exception is a microphone with a metal diaphragm of around 1 fim, which may be about 6 dB less. coupling elements Ce = electrical capacity (acoustical terminals open) L, = diaphragm mass L2 = air mass in spacing and holes R, = air resistance in spacing and holes Figure 14 — Electrical circuit diagram and equivalent diagram for stretched diaphragm condenser microphone.The vibration sensitivity will thus be the same for

Typical vibration The modulus of elasticity is very low compared to metal , especially the good electret materials like FEP are rather soft. This calls for a special r C, . 4 C (tl 0 symbols see fig. h. Fig. 5. Electrical circuit diagram and equivalent diagram for electret condenser microphone.For the capacitor microphone to function a voltage must he applied across it, and this also has the effect of pulling the diaphragm back towards the fixed plate by means of electrostatic attraction. Thus it is kept taut and rigid, Some models make use of this principle to achieve a wide choice of polar

To conclude, the output The condenser microphone is mainly used for precision noise measurement while the piezoelectric microphone, cheaper and less stable, is used for generalpurpose noise measurement. The electret microphone has been widely used for nonprofessional purposes, e.g. in cassetterecorders, radio sets, and public address systems, and has recently increased its share in both precision and generalpurpose noise measurements. 7.1.1.
