摘要:
A telephone handset comprises elongated complementary upper and lower housing members that mate at their perimeters to form a hollow handset housing. The lower housing member includes a pair of spaced apart transducer receiving cavities, each being shaped to receive a cylindrical transducer surrounded by a flexible tubular gasket and form an acoustic seal therewith. Each gasket includes flanges around its circumference that project radially outward and in a direction opposite to the direction of insertion of the transducer/gasket assembly into its associated cavity. Such construction provides adequate mechanical retention between the transducer and the lower housing member and avoids the need for additional retaining hardware. The upper housing is joined to the lower housing using one or more pairs of side-mounted, interlocking hooks and latches. The upper housing further includes ribs, molded therein and positioned to maintain the transducers in place when it is joined with the lower housing.
