Described top flat and lateral plate are formed in one and make.
Described cavity, resonant rod and resonant cap are made by copper product.
Compared with prior art, present invention have the advantage that
(1) present invention use resonant rod be removably installed in the design of cavity inner wall, it is possible to dismounting and fixing resonance bar the most easily, so that the optimizing regulation of properties of product is more flexibly and conveniently.
(2) resonant cap in the present invention uses the lateral plate at four sides, and be arranged on the end face of resonant rod, on the premise of keeping properties of product constant, small volume occupied by resonant cap, and the length of resonant rod also can suitably reduce, the volume enabling the cavity of receiving resonant rod and resonant cap reduces to a great extent, thus reduce further material cost, and meets the needs of finished product miniaturization.
