Abstract

The invention relates to a quartz crystal resonator with a thermistor, which comprises a substrate, a quartz crystal and the thermistor. The upper surface of the substrate is provided with a first frame-shaped part; an interior casing of the first frame-shaped part and the upper surface of the substrate form a first space; the lower surface of the substrate is provided with a second frame-shaped part; the interior casing of the second frame-shaped part and the lower surface of the substrate form a second space; the substrate in the first space is provided with a first electrode part; the substrate in the second space is provided with a second electrode part; the first electrode part in the first space is connected with the quartz crystal; the thermistor is fixed on the second electrode part in the second space; and a cover body is fixed on the first frame-shaped part in a sealed way. According to the invention, the problem of miniaturization of the quartz crystal resonator is solved; the first space is separated from the second space by the substrate; and at the high temperature, gas which is volatilized by a conducting material of the electrode part cannot be attached to the quartz crystal and the thermistor.

Description

technical field [0001] The invention belongs to the technical field of quartz crystal resonators, in particular to a quartz crystal resonator with a thermistor. Background technique [0002] The quartz crystal resonator can output an oscillation signal whose frequency changes according to the pressure applied to the quartz crystal resonator. However, the oscillation frequency of a quartz crystal resonator has temperature characteristics and changes according to temperature. The temperature of the quartz crystal resonator must be known by the thermistor in order to compensate for the oscillation signal. [0003] Japanese Patent Application Laid-Open No. 2008-205938 discloses a piezoelectric device with a thermistor element. The patent utilizes the piezoelectric device so as to compensate the temperature characteristic of the oscillating signal. However, the piezoelectric device has the problem that it is difficult to miniaturize the electronic device, and its thermistor is ...
