ON THE IMPROVEMENT OF THE MATHEMATICAL MODEL OF THE ELECTROACOUSTIC TRANSDUCER UNDER THE CONDITION OF A THIN DOUBLE LAYER IN THE POROUS STRUCTURE OF THE TRANSDUCER BODY

In the approximation of a thin double layer, simple dependences of the acoustic fields excited in an electrokinetic electroacoustic transducer on the velocity of the Helmholtz—Smolukhovsky osmotic movement are obtained. From the dependencies it follows that in the absence of losses, when the nonlinearity of the fluid motion equation does not yet affect and there is no turbulent mode of fluid motion in the transducer body, the magnitudes of the amplitudes of the acoustic velocity and pressure linearly depend on the magnitude of the Helmholtz—Smolukhovsky electroosmotic motion velocity.
