The invention provides a resonance structure and a filter device, and relates to the technical field of electronic devices. The resonance structure comprises a shielding assembly, wherein the shielding assembly comprises a first shielding layer and a second shielding layer, the first shielding layer and the second shielding layer being opposite to each other and arranged at an interval; a resonance assembly which comprises a resonance column and a resonance disc connected with the resonance column, wherein the resonance column is located between the first shielding layer and the second shielding layer and connected with the first shielding layer, and the resonance disc and the second shielding layer form a first capacitor; and a tuning assembly which is positioned between the resonance disc and the first shielding layer, is connected with the resonance column and is used for forming a second capacitor with the second shielding layer. Based on the arrangement, the problem that the resonant frequency of the resonance structure is difficult to reduce in the prior art can be improved.
Description
technical field [0001] The present application relates to the technical field of electronic devices, in particular, to a resonant structure and a filter device. Background technique [0002] In the technical field of electronic devices, the miniaturization of devices (especially some precision devices, such as millimeter wave filters) is particularly important. Wherein, the filter device is generally composed of a resonant structure, so that the volume of the resonant structure determines the volume of the filter device. Therefore, in the prior art, the volume of the resonant structure is generally reduced so that the filter device can be miniaturized. [0003] The inventors have found through research that, in the prior art, in order to reduce the volume of the resonant structure, it is difficult to effectively reduce the resonant frequency of the resonant structure. Contents of the invention [0004] In view of this, the purpose of the present application is to provide...
