Public address system for travelling businesses for public amusement

摘要

This system consists of a central source for sound information signals and individual electro-acoustic transducers driven by these signals, which are arranged in or on the individual vehicles of the travelling business and are directed towards the passengers in order to keep any noise contamination of the environment as low as possible. The transmission between the central sound information source and the transducers in the vehicles can be effected via electric line connections or wirelessly, preferably by radio, where such connections are difficult to implement. Such a system has the additional advantage that the passengers can be provided with proper stereophonic sound. IMAGE
