Title:
RESONANCE COLUMN AND RESONATOR
Document Type and Number:
WIPO Patent Application WO/2015/131687
Kind Code:
A1
Abstract:
A resonance column and a resonator. The position close to a fixed end in a side surface of the resonance column curves toward the inside of a column body, so as to form a gap which intersects with the bottom surface of the resonance column. A gap is arranged at the fixed end of the resonance column, so as to reduce the area of contact between the resonance column and a filter or a metal firmware, thereby reducing the shear stress in the direction of a fixed plane (such as the plane of contact between the bottom surface of the resonance column and the filter/metal firmware), so as to delay the occurrence of phenomena that the fixed point falls off, the edge of the resonance column cracks and even fractures, etc., and therefore, the service life of the resonator is prolonged.
