ABSTRACT:
A portable device including a housing and an electro-acoustic transducer. The housing has a first surface with an outlet for the egress of an acoustic signal when in a loudspeaker mode and a second surface with an outlet for the egress of an acoustic signal when in an earpiece mode. The electro-acoustic transducer is located within the housing and converts an electrical signal input to the transducer into an acoustic signal. The transducer is operable to output acoustic signals when in the loudspeaker mode or the earpiece mode, the audio path between the transducer and the outlet for the egress of an acoustic signal when in the loudspeaker mode being less attenuated than the audio path between the transducer and the outlet for the egress of an acoustic signal when in the earpiece mode.
