    Voltage Controlled Voltage Sources (VCVS) - Power a Piezo Buzzer

    Hi, I am trying to power a Piezo Buzzer between 3.3VDC and 5VDC. The voltage is being adjusted so the sound is low (at 3.3VDC) and loud(at 5VDC). My attachment can be a little misleading. Alarm_low doesn't suggest the volume is low, just the number of beeps. Same holds true for Alarm_medium...
