Abstract: The invention concerns a low profile, liquid sealed audio component assembly (100). The assembly can include a seal (112) having an opening (114), a membrane (120) that can cover the opening and that can substantially block liquid from entering the seal and an audio component (122) contained within the seal and positioned outside a coverage area (C) underneath the membrane. The membrane can transfer acoustic signals to or from the audio component. In addition, the coverage area underneath the membrane can correspond to the area of the membrane that can receive acoustic signals. As an example, the audio component can be a microphone.

Abstract: A method (200) of assembling a mobile communications unit (120). The method (200) includes the steps of producing (212) a universal base component (118) at an assembly facility (110) and shipping (214) the universal base component (118) to a separate facility in which the separate facility contains a selection of user interfaces (122). The user interfaces (122) are used to initiate a feature in the mobile communications unit (120), and the selection of user interfaces (122) includes user interfaces (122) associated with different customers (114). The method (200) also includes selecting (216) a user interface (122) from the selection of user interfaces (122) and incorporating (218) the selected user interface (122) into the universal base component (118) at the separate facility.
