ABSTRACT:
The packaged piezoelectric resonator comprises a case (170; 270) with a lid (140; 240) and a piezoelectric resonator element (110) housed in said case, The piezoelectric resonator element includes a planar tuning-fork-shaped part with two parallel vibrating arms (112, 114), and an additional attachment arm (118) intended for fixing the resonator element (110) to the bottom (172) of the case (170). The inside surface of the lid (140, 240) is stepped in such a way as to form a first portion (142) where the lid has a first thickness and a second portion (144) where the lid has a second thickness substantially greater than the first thickness, the first portion (142) extending at least over distal end portions (166, 168) of the vibrating arms (112, 114), and the second portion (144) extending at least over a part of the attachment arm (118).
