Abstract A new design idea for a monopole acoustic transducer which increases the frequency band and improves electromechanical performance is proposed with a focus on the lowest order of the radial and flexural modes. Numerical modeling of the resonance frequencies and electrical conductance are conducted with respect to the dimensions and material parameters of the proposed transducer. The transmitting voltage response level with respect to the density and velocity of the fluid media is calculated. The numerical simulation is validated through experiments. The frequency band and the electromechanical performance of the monopole acoustic transducer can be optimized by the given methods concluded from the numerical results.
