1. A quartz oscillator, comprising:
a first plate made of monocrystalline quartz;
a second plate made of monocrystalline quartz; and
a quartz sheet, having an oscillation zone and located between the first plate and the second plate, wherein:
the first plate has a first outer surface, a first side surface, and a first connection surface, the first connection surface is located between the first outer surface and the first side surface, and the first outer surface, the first side surface, and the first connection surface are not parallel to each other;
the second plate has a second outer surface, a second side surface, and a second connection surface located between the second outer surface and the second side surface; and
an angle between the second connection surface and the second outer surface is greater than an angle between the first connection surface and the first outer surface.
