Ep0265: Make Your Mobile Phone's Speaker Louder

If you want to get a little more volume from the tiny speaker in your mobile phone you can always go to your EQ settings & push all the levels up, but if you want to save battery (since getting the EQ to push out more sound uses more battery) or give it an extra boost past that, just angle the speaker against a hard surface (or two) or drop it into a glass to get some acoustic amplification. Note that the type of surface you're using will change the sound (e.g. a wooden surface will usually sound better than a glass surface, as the surface itself colors the sound). - Jeff MacArthur
