Quartz resonator of small dimensions

Quartz resonator of small dimensions

The resonator has a base (12) formed of a fixation zone (121), a central zone (122) and a zone (123) opposite to the zone (121). Two vibrating arms (13a, 13b) extend from the zone (123) that has a cut at the fixation level of the arms. Grooves (141a-144a, 141b-144b) are formed on upper and lower sid...

Zusammenfassung:The resonator has a base (12) formed of a fixation zone (121), a central zone (122) and a zone (123) opposite to the zone (121). Two vibrating arms (13a, 13b) extend from the zone (123) that has a cut at the fixation level of the arms. Grooves (141a-144a, 141b-144b) are formed on upper and lower sides of the respective arms. The base has a hole (15) across the central zone, where the hole lengthens the effective length of the arms. An independent claim is also included for a vibrator with a case in which a piezoelectric resonator is fixed.
