Abstract
A mobile phone comprises an car-piece for transmitting sound in a first direction a transducer for converting electrical signals into speech sound, and a dielectric member having an acoustic duct that extends in a direction that is normal to the first direction, the acoustic duct guiding sound generated by the transducer to the ear-piece. By this arrangement all radiating parts of the mobile can be kept away from the ear. The earpiece is movable relative to the casing of the mobile phone.
Claims13
A mobile phone assembly comprising:
- a housing that contains a radio transceiver and that supports an aerial;
- an ear-piece for transmitting sound in a first direction:
- a transducer for converting electrical signals into speech sound:
- and a dielectric member having an acoustic duct that extends in a longitudinal direction that is normal to said first direction, said acoustic duct guiding sound generated by said transducer into said car-piece.
A mobile phone assembly according to any preceding claim wherein said duct is several centimeters long.
A hands-free kit for a mobile phone comprising:
- an electrical cable terminating in a connector,
- a microphone for delivering speech signals to said connector via said cable.
- an ear-piece for transmitting sound in a first direction,
- a transducer for converting electrical signals received from said connector into speech sound;
- and
- a dielectric member having an acoustic duct that extends in a longitudinal direction that is normal to said first direction, said acoustic duct guiding sound generated by said transducer into said ear-piece.
