Abstract:
1. A structure for supporting a vibrator, said structure comprising: a substrate; and a pair of bonding wires fixed to said substrate and connected with said vibrator, said bonding wires being aligned substantially along a central axis of the substrate, each of said bonding wires comprising a wider portion and a narrower portion, said wider portion being directly connected to said substrate and said narrower portion being directly connected to said vibrator, wherein said vibrator is supported with said bonding wires so that said vibrator is not directly contacted with said substrate, and wherein “fd” and “fw” satisfy the following formulas (1), (2) and (3), provided that “fd” represents a resonance frequency of a driving vibration mode of said vibrator and “fw” represents a characteristic frequency of a vibration mode of said bonding wires at room temperature
