Acoustic characteristic analysis of a Langevin transducer attached with a circular plate supported on a concentric circle

Abstract A theoretical forced vibration model for a Langevin transducer with a circular plate supported by concentric circles was proposed, and an analytical solution was derived. The vibration displacement of the plate, excited by the transducer, was found to vary with different plate sizes. Results from the proposed analytical method were compared with those obtained using a commercial finite element method, confirming the model’s validity. This study provides a practical approach to predict and analyze the acoustic behavior of Langevin transducers for effective energy transfer to the surrounding medium.
