MOBILE TELEPHONE EXTENSION UNITS

摘要

A mobile telephone extension unit (1) comprises a remote housing (4) adapted to be located in the vicinity of an upper part of a car dashboard. A loudspeaker (5) and booster amplifier are provided within the housing (4), and a connecting cable (2) connects the unit (1) to a mobile telephone when the telephone is received within a holder located in the vicinity of a lower part of the car dashboard. Since the loudspeaker (5) is positioned at a location which is much closer to the driver's ears, and in view of the boosting of the voice signal by the amplifier, such a unit will considerably enhance the voice quality heard by the driver. In addition a remote microphone (10) may be connected to the unit (1) by a microphone lead (11), the microphone (10) being mounted on the car windscreen so as to be in the best position for receiving voice signals from the driver.
