Ear Speaker Not Working

What is Earpiece or Speaker in a Mobile Cell Phone?

Earpiece or Speaker in a mobile cell phone is an ELECTRONIC COMPONENT or PART that helps to listen to sound during phone call. It is also called Speaker or Ear Speaker. Earpiece is controlled by Audio IC or Power IC (UEM).

Types of Faults or Mobile Phone Earpiece Problem Problems


  • No sound during phone call.
  • Less sound during phone call.
  • Sound with interruption.

How to Solve and Fix Earpiece or Speaker Fault in Android Smartphone and iPhone

  1. Check Speaker Volume during Phone Call.
  2.  If speaker volume is OK the Check Earpiece / Speaker USING A MULTIMETER.
  3. Keep the Multimeter in Buzzer Mode. Value must be 25~35 Ohms. If the Value is NOT between 25~35 Ohms then change the Earpiece / Speaker.
  4. f the problem is not solved then Check CIRCUIT Track of Earpiece Section. DO JUMPER  Wherever required.
  5. If the problem is not solved then Heat, Reball or Change the UEM / Audio IC.
  6. If the problem is still not solved then Heat, Reball or Change the CPU.
NOTE:

If there is less sound or sound is not clear during phone call then change the speaker.

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.
