1. A method for providing a private speaker phone output signal, comprising:
- providing a voice communication device;
receiving at said voice communication device a transmitted first voice signal;
providing a first acoustic transducer interconnected to said voice communication device; and
outputting a first ultrasound signal from said first acoustic transducer, wherein said first ultrasound signal produces an audible reproduction of said first voice signal along a first projection path.

Abstract
The present invention is directed to the provision of a personalized speaker phone and hands-free telephony. In particular, the present invention allows communications to be output along a narrowly defined path, rather than being broadcast. In this way, a private voice communication signal can be provided to a user, even though the user is not holding the output device to the user'"'"'s ear. Furthermore, by providing audible signals along narrowly defined paths, different audible signals may be provided to users at the same location, without interfering with one another.
