A portable wireless handset with enhanced acoustic functions is disclosed having a chamber gasket that has an opening sized to receive a speaker. When inserted into the opening, the speaker seals to the chamber gasket. The chamber gasket also seals to a support surface, so that a sealed acoustic chamber is created. The keypad has an opening in the user interface area for receiving a speaker, and a navigation input key may be positioned over the speaker. In this way, the speaker shares an area with the navigation key, and projects sounds through vents in the navigation key. With the speaker sealed to the keypad, and the keypad sealed to a printed circuit board, a sealed acoustic chamber is formed. Acoustic energy emitted from the back of the speaker is received into the sealed chamber, thereby improving the sound quality for sound projected from the front of the speaker.
