As it is output from the emitter follower, the output resistance is very low. Output voltage can be decided by R1, R2 piezoelectric resistance. If you want to get sinusoidal signal without distortion, you can access resistor R3, its value is determined by the test adjustment. In the case of parameters, the frequency of the circuit is about 500Hz.
