字幕表 動画を再生する 英語字幕をプリント If you're experiencing audio issues with an iPhone, the problem is more than likely the software, not the hardware. Turn it off and on again, and you'll usually be all set. If you are still having audio issues or you just want a deep clean, here is how to clean your phone's speakers. We will be cleaning an iPhone 12 mini for this example. The best way to clean dust and dirt from the front speaker of an iPhone is with a brush with soft bristles, like a paintbrush. Gently brush across the speaker from bottom to top, moving across the length of the long, thin speaker several times. You can also use the soft brush to clean the bottom speakers by working the bristles into the holes. Another way to clean debris from the bottom speakers of an iPhone is with a toothpick. In this video, I will be using a plastic one. Gently insert the sharp point of the toothpick into the speaker holes, then slowly tilt the toothpick until it pops out. Always pick from side to side and out; never push into the phone. Painter's tape is another tool you can use for cleaning your iPhone speakers. Roll up a little bit of tape sticky side out and stick it on your front speaker. Lift to remove debris. You can also roll up the tape to form a point and lift dirt from the bottom speaker holes. You should now have an iPhone that is a little cleaner and better-sounding than before.
