Abstract

Portable digital sound storage and playback equipment, characterized in that the previously recorded sounds, consisting of explanations about specified objects, are played back by means of a computer program resident in the processing unit, which controls both the sound recording and playback, as well as charging and power supply. Playback is performed by taking the data from the storage unit, which is processed and filtered by a DSP with the object of converting it into final sound data that will be transformed by a digital-to-analogue converter into audio signals, which once filtered are amplified and sent to earphones, via which the explanations can be received.
