ABSTRACT:
A resonator which is capable of modulating frequencies has a main body having a vibrating body and an elastic supporting body supporting the vibrating body and a frequency modulating unit having a movable contacting part that is movable between a first position away from the elastic supporting body and a second position which is contactable with the elastic supporting body. Since there is a variable vibration length of the elastic supporting body during vibration of the vibration body by the contact between the contacting part and the elastic supporting body, it is possible to change the frequency of vibration extracted from the resonator, when it is necessary.
