ABSTRACT:
In a mechanical filter, a pair of transducer elements of truncated circular cross-section are disposed at the input and output sides respectively, and they are mechanically connected in cascade to each other by means of a coupler member. The areas of the truncated cross-section of the transducer elements are made different from each other. Between said pair of transducer elements may be provided one or more resonator elements each provided with a recess and connected to each other and to said transducer elements by said coupler member. Each of the transducers and resonators are mounted on a mount base plate by means of a bent wire-like support member having a pair of legs. The foregoing mechanical filter is accommodated in a container which is pressure-reduced and hermetically sealed.
