carbon microphone उदाहरण वाक्य

One illustration of this amplifier effect was the oscillation caused by feedback, resulting in an audible squeal from the old " candlestick " telephone if its earphone was placed near the carbon microphone.
Examples of displacement-responding sensors include the mechanical action of Roland A50 featured a pressure sensing resistor, similar in principle-of-operation to a carbon microphone, in each key.
The principal advantage of carbon microphones over other microphone designs is that they can produce high-level audio signals from very low DC voltages, without needing any form of additional amplification or batteries.
Carbon microphones are also widely used in safety-critical applications such as mining and chemical manufacturing, where higher line voltages cannot be used, due to the risk of sparking and consequent explosions.
Alexander Graham Bell's primitive telephone used them interchangeably ( without any amplification ) before the carbon microphone was invented by others . talk ) 03 : 21, 22 March 2010 ( UTC)

Alternatively, the Wente style condenser microphone used with the Western Electric licensed recording method had a brilliant midrange and was prone to overloading from sibilants in speech, but generally it gave more accurate reproduction than carbon microphones.
Tigerstedt also predicted such future inventions as television and the mobile phone, and in 1917 he filed a patent for what he described as a " pocket-size folding telephone with a very thin carbon microphone ".
