摘要：A device for transforming a digital signal into an acoustic signal, making use of astandard phase modulation, that comprises a modem chip () with a phase modulation of

known kind, used until now for the data transmission via cable, conceived and used onlyfor a cable connection, for acquiring a digital signal through a serial inlet RS232 and formodulating the same according to a standard record V.22, and an acoustic transducer ()of the piezoelectric kind guided by the modem chip ().
