Abstract
An electro-acoustic communications unit ( ) such as a mobile telephone and a telephone handset or headset. The unit has a receiver transducer ( ) generating sound signals from a first side ( ) of the transducer, and the sound signals are output from the unit through one or more openings ( ) in the housing ( ). The transducer ( ) is secured to a structure of the unit with its first side facing away from that structure. The transducer can thereby be placed at any desired location in the unit including in particular other structures than the housing wall, and a volume in the housing is included in the sound path from the transducer to the user's ear. The telephone can thus be very compact and still be leak-tolerant.
