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.
