Unhappy [Q] Loud speaker not working anymore

right,i recently put my phone under a cold water tap to give it a clean and the loud speaker stopped working..it made a cackly noise and now the music is just about audible if i put my ear right up to the speaker port. I ordered a new loud speaker from ebay and its doing the same thing.its been about a week now since i rinsed it under the tap any ideas anyone id be so gratefull.thanks in advance
