The paper is a discussion of the construction of an alarm siren based on the active piezoelectric element. The influence of various parameters on the loudness of the siren was investigated. Efforts to increase the efficiency of selected design were made. The simulations carried out based on an ANSYS. Individual dimensions of a piezoelectric transducer were selected as well as a collaborate diaphragm. The possibility of using different piezoelectric materials was also analyzed. All tasks and computer simulations were aimed at receiving a siren structure able to obtain the highest sound pressure level at selected frequency.
