About MyPhoneSpeaker

MyPhoneSpeaker is a free browser tool and a set of guides for a phone speaker that sounds muffled after it got wet.

Who runs this site

Built and maintained by Marcus Brown. Independent phone repair technician with more than 8 years at the repair bench.

Marcus Brown is an independent phone repair technician. He has more than 8 years of hands-on bench experience with iPhone and Android phones. His work includes liquid-damage diagnosis, micro-soldering of audio chips, and speaker replacement.

In that time he has opened hundreds of water-damaged phones, from sink splashes to salt-water submersions. In his experience, a common problem is not a dead logic board. It is water held in the fine mesh of the speaker grille.

Customers often asked him if online "water eject" sites work. So we measured the sound files that 10 popular speaker cleaner sites serve. Of 6 distinct "water" files, only 1 has its main frequency in the 150 to 300 Hz range. One widely copied file plays 530 Hz and then a 15 Hz square wave.

Why this site exists

One widely copied cleaner file we measured plays a different signal. Many sites repeat the 165 Hz figure without data.

We want an honest tool. Our tone is generated in your browser, and we publish its values. The tool shows the planned frequency and the measured frequency while it plays. We also publish what independent tests found, including the limits.

What we do not claim

  • We do not claim a success rate. No test we found gives one.
  • We do not claim the tone dries your phone, repairs water damage, or works on the charging port, the SIM slot, or the buttons.
  • We do not claim the tone removes dust or lint.
  • We do not claim that 165 Hz is a proven or best frequency.
  • We are not a repair service. We do not diagnose your phone.
