  • Patent number: 5463688
    Abstract: A telephone mounting receptacle (100) releasably affixes a portion of a cellular telephone thereto. Two facially opposed simultaneously retractable latch members (130, 140) engage with the portion of a cellular telephone when the retractable latch members (130, 140) are positioned in the latch position. An actuation force applied to either the right force receiving surface (162), or the left force receiving surface (163) of the mounting receptacle (100), simultaneously positions the retractable latch members (130, 140) into a release position. A spring-loaded element (170) applied against the bottom face of the telephone additionally works to "eject" the telephone. At this point, the telephone can be removed from the mounting receptacle (100).

  • Patent number: 5081674
    Abstract: A double annular ring gasket (202) interfaces a speaker (201) to a housing (200) in a portable radiotelephone, providing a conformal and acoustic seal between the speaker (201) and the housing (200), and compensating for dimensional tolerance between the housing (200) and the circuit board subassembly (204) on which the speaker (201) is mounted. The gasket (201) includes outer ring (205), inner ring (206) and intermediate ring (207) therebetween. The gasket (202) is inserted into a cavity (203) in the housing (200). Then, the speaker (201), as part of a printed circuit board subassembly (204), is pressed into place against the outer ring (205) of gasket (202) to form an axial seal and the inner ring (206) is deformed radially by the speaker (201) to form a conformal seal.
