HOW TO TEST MOBILE PHONE MICROPHONE OR MOUTHPIECE

Mobile phone microphone also known as mouthpiece is the one that intercepts the voice to transmit to other mobile phone users. Without it or a defective one will result that the other user on a phone cannot hear the one with a defective microphone on its mobile phone handsets.

A technical term of a microphone is a device used to convert sounds into electrical signal.

A microphone is made of an electrical magnetic wire shaped into a round coil with a magnet metal surrounds it, the mechanical vibration generated by it will then produce an electrical voltage signal.

Checking the microphone is also been so easy, Just set the analog or digital multi-tester to x1 resistance value then attach both test probe to its terminal. A good sign of a working microphone tends to have a reading while the busted one will have no reading. In some other cases types of microphones may only have a reading to the range of x10 for some high resistance value.

How do I test the microphone on my smartphone, tablet or other portable device?

Testing microphones embedded in devices such as tablets, phones and other mobile devices can be challenging as they typically don't have the internal signal routing to return the test signal back to SoundCheck. In cases like these, an "open loop" measurement process can be employed.

A Sound Check example sequence, Open Loop Microphone Sequence demonstrates how to measure such a device by recording a signal on the device under test, transferring that recording to the computer running Sound Check and then using a Recall step to import the recorded time waveform into Sound Check for analysis.

It’s a good idea to first check the following things and see if they solve the problem:

1. Check that your microphone is connected to the correct (normally pink) socket in your computer.If it’s a mic with a USB connector just make sure it is properly connected to the USB socket (you will not use the pink microphone socket in this case).
2. Check that your microphone is not muted – sometimes the mic has a mute button on it or on the wire that is connected to it.
3. Check that the volume on the microphone is not turned all the way down.
