摘要

A flip-type communication device 200 includes a base housing 220 and an auxiliary housing 225. The base housing has an audio output 320 and the auxiliary housing has an earpiece 240 for another audio output. An unattenuated acoustic path has an input end coupled to an audio transducer 115 and an output end coupled to the audio output 320 while an attenuated acoustic path has an input end coupled to the output end of the unattenuated path and an output end coupled to the earpiece region 240 during a privacy mode and having the input end uncoupled from the output end of the unattenuated path during a speakerphone mode.
