        piezo crystal is electric motor. you input deformation of the crystal and get potential difference on opposite sides. other way around also works

            it’s a special case there, because for frequencies in question mechanical quartz resonator has much higher Q than any electrical resonator you can practically build. that is, mechanical properties of piezo crystal stabilize voltage oscillations
