The disclosure relates to the creation of a secure audio link between a user and a mobile computing device, such as a laptop or a tablet computer A. It is stated that sound originating from hypersonic speakers B may be used to direct audio securely to the user of the mobile computing device. Lasers may pick up the users voice by means of reflection analysis. A camera may monitor the users movement and direct the hypersonic sound and the lasers accordingly. It is also stated that sound cancellation may be used to silence the users voice to others in a room. In this way, the described system is said to allow private conversations without requiring the user to hold the device to the ear. Also disclosed is a tilt mechanism (figs. 2-7) |
