Abstract

A resonator includes a body shaft portion, a resonant disk portion and a coupling face portion. The body shaft portion has a top end and a bottom end. An inner cavity is slotted between the top end and the bottom end. The resonant disk portion is integrally formed on the top end. The coupling face portion is integrally formed on the bottom end. The body shaft portion includes a first outer surface and the coupling face portion includes a second outer surface. A first connecting arc surface is formed between the first outer surface and the second outer surface. The inner cavity has a central axis. In a transverse section perpendicular to the central axis, a wall thickness T of the body shaft portion is 0.5 mm˜1 mm and a first arc length R1 of the first connecting arc surface is no more than 0.25 mm.
