ABSTRACT:
Acoustic signal apparatus, especially used as time tapper for sportive interval trainings, having a signal giving device (3) producing acoustic signals, said signal giving device (3) being controlled by a master clock device (1) to produce a plurality of acoustic pulses mutually shifted by predetermined clock intervals. Mutually different acoustic pulses are produceable by the signal giving device (3), and the signal giving device (3) is controlled by the master clock device (1) in such a way that the mutually different acoustic pulses are mutually time shifted alternatingly in cyclical repetitions for predetermined clock intervals, said clock intervals being adjustable independently of each other by the adjusting device (13, 14) of the master clock device (1).
