Sonitron Digital Square refers to a technology that is driving a piezo cup membrane mounted in a cavity, with a square wave. The combination of drive frequency and the high quality response of the cup membrane adjusted to the best acoustic function of the cavity in which the cup membrane is mounted, offers an extremely high sound output.
The drive signal to the piezo is a square wave with a sufficient (Vpp) peak to peak voltage. Square wave pulses contain very rich harmonic content of energy.
The tuned square wave signal with rich harmonics is driving the piezo cup membrane, the acoustic function of the cavity combined with the piezo cup and the drive frequency is tuned until max. sound output for several harmonic frequencies. The character and pitch of the sound output wave can be adjusted to the desired acoustic signal.
