Abstract
Disclosed herein is a resonator including, a vibrating portion having a conductor portion, and three or more insulating portions provided so as to electrically separate the conductor portion into a plurality of blocks, wherein when a potential difference is caused across both ends in each of the three or more insulating portions, the vibrating portion carries out a resonance vibration based on a longitudinal vibration in accordance with a frequency of an A.C. signal inputted to each of corresponding ones of the plurality of blocks in the conductor portion.
Claims20
A resonator comprising:
- a vibrating portion having a conductor portion;
- and
- three or more insulating portions embedded in the conductor portion so as to electrically separate the conductor portion into a plurality of blocks;
- wherein when a potential difference is caused across both ends in each of said three or more insulating portions, said vibrating portion carries out a resonance vibration based on a longitudinal vibration in accordance with a frequency of an A.C. signal inputted to each of corresponding ones of said plurality of blocks in said conductor portion.
A method of manufacturing a resonator, comprising the step of forming a vibrating portion having a conductor portion, and three or more insulating portions embedded in the conductor portion for electrically separating said conductor portion into a plurality of blocks, and carrying out a resonance vibration based on a longitudinal vibration in accordance with a frequency of an A.C. signal inputted to each of corresponding ones of said plurality of blocks in said conductor portion when a potential difference is caused across both ends in each of said three or more insulating portions on a substrate.
An oscillator, comprising:
- a resonator for carrying out a resonance vibration;
- said resonator including, a vibrating portion having a conductor portion, and three or more insulating portions embedded in the conductor portion so as to electrically separate said conductor portion into a plurality of blocks;
- wherein when a potential difference is caused across both ends in each of said three or more insulating portions, said vibrating portion carries out a resonance vibration based on a longitudinal vibration in accordance with a frequency of an A.C. signal inputted to each of corresponding ones of said plurality of blocks in said conductor portion.
An electronic apparatus, comprising:
- a resonator for carrying out a resonance vibration;
- said resonator including, a vibrating portion having a conductor portion, and three or more insulating portions embedded in the conductor portion so as to electrically separate said conductor portion into a plurality of blocks;
- wherein when a potential difference is caused across both ends in each of said three or more insulating portions, said vibrating portion carries out a resonance vibration based on a longitudinal vibration in accordance with a frequency of an A.C. signal inputted to each of corresponding ones of said plurality of blocks in said conductor portion.
