This paper is a report on analyses and experiments of the electromechanical filter emiployed tuning-forks with couplers. The composition of this filter is simple: it is composed of two identical tuning-forks coupled each other with fiexural and torsional vibrating couplers. The filter whose center-frequency is situated in audio-frequency range from 0.1 to 20 KC is expected to be put to practical use hereafter, since the tuning-fork is suitable for use in this frequency range. This filter of coupler type has a merit of obtaining wider band-characteristic than that of the differential-connection-type filter, and it is able to be analyzed easily for the symmetry of its equivalent network.　In the first, the various constructions of the filter are described. Then the theoretical analyses are explained on the narrow band filter of the simple construction of only two tuning-forks and couplers, and on the wide band filter obtained by the method of impedance-transformation. Lastly, a few experimental results on these mechanical filters are shown.
