This invention relates to a tuned electrolytic detector and more particularly to a pressure sensitive electrolytic cell of a character in which increased sensitivity to pressure changes applied thereto may be obtained throughout a predetermined controlled frequency band, thereby increasing the sensitivity in the desired controlled frequency band for devices such as acoustic filters in which the tuned electrolytic detector is used. More particularly, it is a purpose of this invention to provide a high d.c. electrical output sensitivity to acoustic pressures by mounting the cathode assembly of the detector on a flexible internal diaphragm for movement therewith. The instant diaphragm is of an inert material and disposed within the detector cell in a manner to effectively provide a separation between the two electrolyte concentrations on opposite sides thereof, and in which arrangement of structure the normal flow path is through an orifice in the mass of the cathode box.
