What is Microphone or Mic in a Mobile Cell Phone?

Microphone or Mic in a mobile cell phone is an ELECTRONIC COMPONENT or CARD LEVEL PART OF MOBILE PHONE that helps to transmit sound during phone call. It is also called Mic or Mouth Piece. Microphone is controlled by Audio IC or Power IC (UEM).

Problems if Mobile Phone Microphone Not Working

  • No sound or Less Sound during phone call.
  • The other Person cannot hear you Voice / Sound.
  • Sound with interruption or Changed sound.

Mobile Phone Microphone Working – Mic Problem and Solution

  1. Check Microphone settings.
  2.  If all settings are OK then, Check and clean Microphone Tips and Connector.
  3. If the problem is not solved then Check Microphone by USING  A MULTIMETER.
  4. Keep the Multimeter in Buzzer Mode. Value must be 600~1800 Ohms. If the Value is not between 600~1800 Ohms then change the Microphone.NOTE: Only one side of the Mic will give value. The other side will not give any value.
  5. If the problem is not solved then Check Track of Microphone Section. DO JUMPER Wherever required.
  6. If the problem is not solved then Heat or Change Microphone IC.
  7. If the problem is still not solved then Heat, Reball or Change CPU.

SURFACE MOUNT TRANSISTOR IN MOBILE PHONE & THEIR FUNCTION

Image
Surface Mount Transistor in Mobile Phone and Their Function Surface Mount Transistor or SMT Transistor is an SMD electronic component  made up of semiconductor material like silicon or germanium. There are 2 types of Surface Mount Transistors: NPN Type PNP Type Terminals of a Transistor There are three terminals of a surface mount transistor or thru-hole transistor: Ammeter (E) – Flows current on receipt of forward bias. Electrons are emitted in NPN transistors whereas PNP transistors emit ‘ holes ’. Collector (C) – The terminal of the transistor which receives the emitted electrons or holes. Collector always works or reverse bias mode. Base (B) – The layer between ammeter and collector is called base. Base displays the property of showing low resistance in ammeter junction forward bias and high in collector junction reverse bias. Facts about Transistor Indicating Character : Q or V, TR Function : Switching, Amplification, Regulating Voltage.
