    • A resonator structure (1200, 1300, 1400), where a certain wave mode is piezoelectrically excitable, comprises at least two conductor layers (110, 120) and at least one piezoelectric layer (110) in between the conductor layers, said conductor layers and piezoelectric layer extending over a first area of the resonator structure, which first area is a piezoelectrically excitable area of the resonator structure. The resonator structure is characterized in that it comprises a frame-like zone (2, 4) confining a center area (3) within the first area, a cut-off frequency of the piezoelectrically excited wave mode in the layer structure of the frame-like zone is different from that in the layer structure of the center area, and width of the frame-like zone and acoustical properties of the layer structure in the frame-like zone are arranged so that displacement relating to the piezoelectrically excited strongest resonance mode is substantially uniform in the center area of the resonator.
    • 一种其中一定波模式是可压电激发的谐振器结构(1200,1300,1400)包括至少两个导体层(110,120)和至少一个压电层(110),位于导体层之间,所述导体层和 压电层在谐振器结构的第一区域上延伸,该第一区域是谐振器结构的压电可激发区域。 谐振器结构的特征在于,其包括限制第一区域内的中心区域(3)的框架状区域(2,4),框架状区域的层结构中的压电激发波模式的截止频率, 与框架状区域的层结构不同,框状区域的框状宽度和层结构的声学特性被布置成使得与压电激发的最强谐振模式有关的位移为 在谐振器的中心区域基本均匀。
