Abstract
Abstract In an exemplary embodiment, a communication device, such as a radiotelephone (100), has within its housing (106) an apparatus for electrically coupling an electroacoustic transducer (201), such as an earpiece, to radiotelephone circuitry (403). The apparatus comprises resilient conductive means, for example conductive barrel springs (213-216), abutting both the conductive contacts on the earpiece (214, 243) and the corresponding conductive contacts on a printed circuit substrate (205, 208, and 206, 207). A bracket (211) manually attached to the printed circuit substrate (203) positions the conductive barrel springs (213-216) while they are compressed between the earpiece (201) and the printed circuit substrate (203) during the assembly of the radiotelephone (100). A plurality of barrel springs (213-216) are used to provide redundant electrical coupling and stability for the earpiece (201). The apparatus advantageously provides for improved manufacturability and convenient replaceability of the earpiece (201).
