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.

An exemplary battery pack comprises a battery cell having a first terminal and a second terminal disposed on a first end of the battery cell. A support member is attached to the first end of the battery cell, and a first L-shaped contact is connected to the first terminal via a protection circuit module. The protection circuit module is configured to disconnect the first terminal from the L-shaped contact upon a disconnect event. A second L-shaped contact connected to the second terminal, and a top cover encloses the first end of the battery cell, the support member and the protection circuit module. The first and second L-shaped contacts are exposed through corresponding apertures in the top cover, and a label including a body section and first, second, third and fourth flap sections is wrapped around the battery cell such that at least one of the flap sections secures the top cover to the battery cell. A cutout area can be provided on one of the flap sections to expose the L-shaped contacts for interfacing with device or connector contacts.
