ABSTRACT:
A transducer converting an oscillation in fluid pressure into an alternating electrical signal comprises a transducer body including a first pressure compartment disposed intermediate a second and third pressure compartment, and separated by from the second and third pressure compartments respectively by two thin partitioning walls, and a relative vibratory motion sensor detecting the relative vibratory deflection between the two thin partitioning walls, wherein the relative vibratory motion sensor generates an alternating electrical signal representing the oscillation in fluid pressure existing in at least one of two pressures respectively introduced into the first pressure compartment and into the combination of the second and third pressure compartments.
