PATENT OF THE WEEK – SOUND REPRODUCER

The invention “sound reproducer” was invented by Hans W. Nixdorf & was granted utility patent on 5^th February 1991 by the USPTO bearing the patent grant number. US4991222A. This invention, in general, relates to a sound reproducer that, when in use, is attached with the user’s head. A sound reproducer of this type typically consists of a sound source, such as a mini-loudspeaker, or a headset loudspeaker, and a suitable device for holding it.

However, when used on a head or support cushion, such headset arrangements are generally bulky, inconvenient, and cumbersome. However, the effect of being completely shut away or screened off from the outside world, which occurs when using traditional headsets, is frequently undesirable. For that purpose, a cushion-like head support arrangement is required, which frequently takes up a significant amount of space when carried around with the device’s user. The arrangement of the invention may also be used in relation to lifejackets, in which case instructions can be transmitted to the wearer of the lifejacket via one or more loudspeakers, according to the concept of the present invention.
