专利汇可以提供Piezoelectric resonator专利检索，专利查询，专利分析的服务。并且A piezoelectric resonator comprises a crystal blade working by flexion and having at least two nodal points, suspension means supporting the blade at one nodal point, and means for limiting movement of the blade located adjacent to at least one further nodal point.，下面是Piezoelectric resonator专利的具体信息内容。
1. A piezoelectric resonator comprising a crystal blade working by flexion and having a central nodal point and at least two lateral nodal points, suspension means supporting the blade at the central nodal point, and means for limiting movement of the blade located adjacent to each of the two lateral nodal points.
2. A resonator as claimed in claim 1, in which the blade resonates in second harmonic.
3. A resonator as claimed in claim 1, in which the limiting means comprises a member having an aperture surrounding the blade at the lateral nodal points.
4. A resonator as claimed in claim 3, in which the said member is deformable upon contact with the blade.
