Problems solved by technology

[0007] However, increasing the thickness of the mounting substrate means that the height of the vibrating gyro itself has increased, which is contrary to the recent trend of lowering the height of most electronic components.

Embodiment Construction

[0020] figure 1 A perspective view showing an embodiment of the vibrating top of the present invention. exist figure 1 Among them, the top 1 has: a vibrator 2; conductive support members 8, 9, 10, 11 made of metal such as plate-shaped Fe-Ni containing gold or phosphor bronze; a mounting substrate 12; the vibrator 2 is excited and flexurally vibrated Components 13 , 14 , 15 for a drive detection circuit that detect an angular velocity applied to the vibrator 2 from a signal output from the vibrator 2 ; and a cover 16 .

[0021] The vibrator 2 is formed by forming the piezoelectric substrate 3 with the electrodes 4a and 4b separated in the width direction on one main surface while being polarized in the thickness direction, and forming the piezoelectric substrate 3 on one main surface while being polarized in the thickness direction. The piezoelectric substrate 5 of the electrode 6 is bonded to each other on the other main surface via the electrode 7 to form a bimorph structur...

Abstract

A columnar vibrator (2) that performs open-ended bending vibration is mounted on one main surface of the mounting substrate (12), and a drive detection circuit is mounted across the abdomen centerline (n2) of the bending vibration caused by the resonance of the mounting substrate (12). Use part (13). In addition, the self-resonant frequency of the flexural vibration of the mounting substrate (12) is lower than that of the vibrator (2), and the self-resonant frequency of the flexural vibration after the vibrator (2) and the drive detection circuit parts (13) are mounted is lower than that of the vibrator (2). The self-resonance frequency of the bending vibration of the monomer is high, and is inconsistent with the bending vibration frequency of the vibrator (2). The present invention provides a vibrating top and an electronic device using the vibrating gyroscope with little change in characteristics between the time of characteristic adjustment before cover mounting and the completion time after cover mounting, although it has a thin mounting substrate and can be reduced in height.

Description

technical field [0001] The present invention relates to a vibrating top and an electronic device using the same. For example, it relates to a vibrating top used in a manual correction device of a television camera and an electronic device using the same. Background technique [0002] A vibrating gyroscope has been disclosed in, for example, Fig. 6 of JP-A-2001-227953 (hereinafter referred to as Existing Example 1). The structure of this vibrating gyroscope is that the node portion is supported by a supporting member so that the longitudinal direction of the vibrator and the installation One main surface of the substrate is parallel, and a columnar vibrator performing bending vibration with open ends is mounted on one main surface of the mounting substrate. [0003] In Conventional Example 1, the vibrator 100 is mounted on one main surface of the mounting substrate 20 (12) by supporting the nodes thereof with the supporting members 104 (8), 105 (9), 106 (10), and 107 (11).
