The acoustic characteristics of a rubber-liquid resonator are calculated, combining the properties of an empty rubber cavity, a Helmholtz resonator, and a water–air resonator, gas bubble in a viscoelastic medium and in a shell, and a bubble in a liquid. The equation of the forced oscillations of the resonator in the sound wave field is obtained by applying the principle of least action. The eigenfrequency of the resonator is calculated. The following sound energy dissipation mechanisms are considered: due to the shear viscosity of rubber, the viscosity of liquid in the neck, heat loss in the air chamber, and radiation loss. Experimental data are presented. Possible resonator applications are discussed.
