Abstract

See full text

Transducer assembly having a head and a transducer element contacting the rear of the head. In order to provide an output signal from the transducer element which has a positive value over a wide range of angles of incidence of shock or pressure waves to be detected by said transducer assembly, the transducer element contacts with the rear of the head over a zone which is smaller in cross sectional area taken perpendicular to the direction of propagation of the shock or pressure wave through the assembly than that of the rear of the head. In order to provide electrical connection to the front face of the transducer element which can be a piezo-electric element, it can be mounted in a metal tube with a partly closed end which electrically contacts the front face of the element. In order to positively position the transducer assembly and to inhibit unwanted shock or pressure waves reaching the element, the assembly has a series path of four interfaces of acoustic mismatch of shock or pressure waves, between said head and a body.
