ABSTRACT:
In a piezoelectric tuning fork of the type which is used as an electro-mechanical filter and wherein a tuning fork is directly supported by a supporting member extended from a terminal plate, the supporting member is surrounded with a vibration isolation or absorbing member which in turn is bonded or otherwise joined to both the supporting member and the terminal plate, whereby the noise output due to the transmission of external vibrations or impacts may be considerably suppressed.
