RESISTANCE OF ARDUINO PIEZO BUZZER DRIVER

There should be a decoupling capacitor next to the driver transistors, which isn't shown. The output power will be around 400mW, thanks to the voltage drop of the emitter followers, which should be loud enough. To drive a 0.5W 8Ohm speaker from an Arduinp I'd recommend using a pair of emitter followers and an AC coupling capacitor. Using one squarewave source and an AC coupling capacitor would reduce the power to half again, at 0.78125W, but the sound output would not change, since the DC component will be blocked. If only one square wave source were used, with the other end of R1 connected to 0V, the power would halve to 1.5625W, but there would be 2.5V of DC across it, which would do nothing but heat the voice coil, if it were a speaker. The RMS current through the 8Ohm resistor is 625mA and the power dissipated 3.125W. V1 and V2 represent differential outputs. That's true, but is completely irrelevant here, as the original poster is talking about driving a load from an MCU output pin, not a linear amplifier, be it class AB or D.

On the other hand you can drive a speaker with a single transistor if you don't mind something crude. pull-up and pull-down) otherwise all you'll hear is the first tick. It's also good to bear in mind that piezos are capacitive, so they don't provide a DC path so it's essential to be able to drive it in both directions (i.e. drive the two ends of the speaker in opposite directions). However with an 8-ohm speaker you could get a reasonable amount of power from a 5v supply, especially if you run it in bridge mode (i.e. A while back I added an alarm sounder to a PCB and ran an H-bridge from a 24v supply to get max output.

You may also find that you need a lot of voltage to get full power. Piezos are typically very dependent on being mounted correctly (glueing to a metal surface or PCB is often seen) and if you hold one in free space there will be very little output. more sound output per Watt input, but if you go away from resonance, even by tens of Hz, you'll get much less. If you drive a piezo at close to its resonant frequency, which is often in the 2 to 8kHz range, you can get higher sensitivity, i.e. Now 80dB is quite loud, noisy indeed, but 1W is also a fair bit of power to deliver (although sound systems often claim to be capable of hundreds of watts, this is unrealistic in normal operation). (Magnetic) loudspeaker sensitivity is generally quoted in dBA per Watt, often at 1m from the speaker.
