Muffled calls or distorted audio? Speaker and microphone faults can be fixed
If your calls sound muffled, your speaker crackles at high volume, or people cannot hear you on calls, the problem is likely your phone’s speaker or microphone assembly. Sigma Mobiles offers speaker and microphone repair in Malta for all major brands starting — diagnosed and fixed same-day in our Hamrun workshop.
Speaker and microphone faults are often misdiagnosed. Before we replace any hardware, we perform a full audio diagnostic: earpiece speaker (the one you hold to your ear), loudspeaker (bottom-firing for speakerphone and media), primary microphone (bottom of phone), secondary microphone (top, for noise cancellation), and the front microphone (used for video recording and voice assistants). A fault in any one of these degrades the calling experience.
Speaker grille debris: the most common fix
Malta’s environment — dry, dusty summers and humid winters — is tough on phone acoustics. Fine particles work past the protective mesh and settle on the speaker diaphragm, causing distortion at certain frequencies. In many cases, a careful cleaning under the microscope restores clear audio without any parts replacement. This is the most common outcome of our phone speaker repair Malta diagnostics.
When cleaning is not enough: hardware replacement
If cleaning does not restore audio quality, we replace the speaker or microphone module. These are small, relatively inexpensive components, but they require careful soldering and routing. On iPhones, the loudspeaker and charging port share a flex cable assembly — a speaker fault sometimes means replacing the entire charge port flex. We diagnose this during the free inspection so there are no surprises.
Water exposure and audio failure
Even a splash can leave mineral residue on the microphone diaphragm, permanently reducing sensitivity. Salt water is particularly damaging — the conductive crystals left behind after seawater evaporates can corrode microphone contacts within days. If your phone has been exposed to water, bring it in promptly. Our ultrasonic cleaning process can often recover water-damaged microphones and speakers if addressed within 48 hours.
