Sound Beacon for the Visually Impaired "Parus" - Enhancing Navigation

Any information can be recorded as audio messages, for example, about nearby objects and the ways of unhindered access to them, the list of services provided in the institution or organisation, the order and hours of operation, etc. In addition, the system can be used as a voice announcement system for businesses and organisations at the same time. The loudspeaker is connected to a standard 100-volt broadcast line of a local sound network, e.g.

in a supermarket, and is able to have a priority value (the loudspeaker broadcast will interrupt any other actions of the sound reproducing device). The sound reproducing device (base loudspeaker) is reliably protected from unfavourable weather conditions, including moisture and rain, and is able to operate at temperatures from -40C to +50C. Built-in battery provides long autonomous operation of the device.
