ABSTRACT:
An electromechanical reed filter has a pair of mechanically resonant reed elements each having an electromechanical transducer. The transducer coupled to a terminal by means a connecting lead is applied with a shock-absorbing member such as resilient adhesive in a position anywhere between the contact point thereof with the transducer and the terminal so that variations in the natural frequency and Q value of the reed elements caused by deformation of the connecting leads due to abnormal shock or other ambient conditions are effectively eliminated.
