Problems solved by technology

However, the negative side is that the position where the base is joined is the front end of the joint, and the vibrating part is the foot, and the actual length of the base is long, so it is difficult to withstand the vibration stress, or the tuning fork type piezoelectric vibrator When the external force is subjected to external impact, the stress or external force is borne by the base part or the joint part, and the piezoelectric vibrating piece is easy to break
In addition, since the joint portion has a long overall length in plan view, it is necessary to ensure a mounting area for mounting the base of the joint portion having a long plan view overall length.

Embodiment Construction

[0080] Hereinafter, a tuning fork type crystal resonator (also referred to as a tuning fork type crystal resonator) will be described with reference to the accompanying drawings. The tuning-fork type crystal resonator 1 used in the present embodiment has a housing formed by joining the base 3 and the cover (not shown) via a sealing member H. As shown in FIG. Specifically, the tuning-fork-type crystal vibrating piece 2 is bonded to the electrode pad 32 of the base 3 with the upper portion opened by plating a metal film M1 such as a bump, and the cover is bonded to the base 3 through the sealing member H. , the container is hermetically sealed (see below). Here, in the present embodiment, the nominal frequency of the tuning-fork crystal oscillator 1 is 32.768 kHz. However, this nominal frequency is merely an example, and other frequencies may also be used.

[0081] The base 3 is constituted by a container body of an insulator made of, for example, a ceramic material, a glass m...

Abstract

A tuning fork-type piezoelectric resonator plate has a resonator blank comprising a pair of vibrating leg portions and a base portion from which the leg portions protrude. The pair of leg portions are arranged in parallel protrudingly from one end face of the base portion, and a pronged portion is formed between the pair of leg portions in an intermediate position in a width direction of the one end face of the base portion. The base portion has a pair of through holes along the one end face of the base portion, and on another end face side opposite to the one end face of the base portion, a joining region that joins to an external portion. The pair of through holes are specially positioned and have special wall surface configurations.

Description

technical field [0001] The present invention relates to a tuning fork type piezoelectric vibrating piece used in electronic equipment and the like, and a tuning fork type crystal vibrator using the tuning fork type piezoelectric vibrating piece. Background technique [0002] Piezoelectric vibration devices represented by piezoelectric vibrators are widely used in mobile communication devices such as mobile phones. As one of piezoelectric vibrating reeds used in piezoelectric vibrators, there is a tuning-fork type piezoelectric vibrating reed. The tuning-fork-type piezoelectric vibrating reed is a tuning-fork-shaped piezoelectric vibrating reed composed of a base and a pair of vibrating legs (hereinafter referred to as legs) extending in the same direction from the base. A tuning-fork-type piezoelectric vibrator using a tuning-fork-type piezoelectric vibrating piece is widely used as a clock source of a clock. [0003] For example, in the tuning-fork piezoelectric vibrating...
