In an exemplary embodiment, a communication device, such as a ra- diotelephone (100), has within its housing (106) an apparatus for electrically coupling an electricoacoustic transducer (201), such as an earpiece, to ratio- telephone circuitry. The apparatus comprises resilient conductive means, for example conductive barrel springs (213-216), abutting both the conductive contacts on the earpiece (241, 243) and the corresponding conductive con- tacts on a printed circuit substrate (205, 208 and 206, 207). A bracket (211) manually attached to the printed circuit substrate (203) positions the con- ductive barrel springs (213-216) while they are compressed between the ear- piece (201) and the printed circuit substrate (203) during the assembly of the radiotelephone (100). A plurality of barrel springs (213-216) are used to pro- vide redundant electrical coupling and stability for the earpiece (201). The apparatus advantageously provides for improved manufacturability and convenient replaceability of the earpiece (201).
