摘要:
The embodiments of the invention concern a keypad (120). The keypad can include a membrane (143), at least one key with at least one flange 150 to overlap with at least one second flange of a second key (146), and at least one audio port opening (107) in the membrane for providing a passage of air from a transducer (101) positioned behind at least one key through the keypad to a main volume area (112). For example, the audio port opening can be in a region of the membrane between the keys, and the overlapping of the flanges obscures a view of at least one audio port opening.
摘要:
A mounting apparatus for securing a mobile radio includes a mounting tray (102) having a flat surface (104), radio housing attachment wings (106) and a pair of radio receiving portions (108). The flat surface has recessed fastening locations (110) for attaching the mounting tray to a surface using screws or bolts. A rubber pad (114) is affixed to the inside of each attachment wing (106) such that an opening (115) in the pad is aligned with an opening (112) in the attachment wing. The radio receiving portions (108) each have a cut-out (109) for receiving the rear of the mobile radio. A high tensile strength spring (118) is riveted (130) to the flat surface (104) of the tray and has an L-shaped end (122) prevents the spring from deforming if an unexpectedly large force is applied to the top of the radio. Together, these features act to dampen any vibrations, etc. which could damage internal radio circuitry.
