Disclosed is a novel piezoelectric quartz wafer with a dual-convex structure. The novel piezoelectric quartz wafer comprises a central component (1), a protection frame (2), and a connection portion (3). A cavity is provided in the protecting frame (2), a boss I (4) is provided on the top surface of the central component (1), and a boss II (5) is provided on the bottom surface of the central component (1). Through grooves A (6) are formed between the two long sides of the protecting frame (2) and the two long sides of the central component (1), and through grooves B (7) are formed between the two short sides of the protecting frame (2) and the two short sides of the central component (1). The through grooves A (6) are communicated with the through grooves B (7). The connection portion (3) is provided in any one of the through grooves B (7). The present invention has the following beneficial effects: the piezoelectric quartz wafer can be used for batch production of small-sized quartz wafers and weaken parasitic vibration generated by the edge; meanwhile, the piezoelectric quartz wafer can strengthen the energy trapping effect of the centre of the quartz crystal wafer, improve working accuracy , and greatly improve product consistency. |
