Abstract
A vibrator 12 includes a regular triangular prism-shaped vibrating body 14. Center portions of two supporting members 18a and 18b are fixed to the vibrating body 14. One supporting member 18a includes a linear intermediate portion 20a extending in a widthwise direction (y-axis direction) of the vibrator 12, and two linear leg portions 22a and 22a bend downward from both ends of the intermediate portion 20a. In this case, a distance W' between tips of the two leg portions 22a and 22a is expanded wider than a length W of the intermediate portion 20a. Similarly, the other supporting member 18b also includes a linear intermediate portion 20b and two leg portions 22b and 22b, a distance between tips of which is expanded.
Claims11
A three-dimensional supporting structure for a vibrator having a supporting member for supporting a prism-shaped vibrator above a mounting board, wherein said supporting member comprising:
- a straight linear intermediate portion being fixed to said vibrator and extending in a widthwide direction of said vibrator;
- and
- two straight linear leg portions extending from both ends of said intermediate portion, each straight leg portion have first and second ends, said second end being a tip fixed to said mounting board, and said first end connected to said straight linear intermediate portion, a distance W' between said tips expanding wider than a length W of said intermediate portion.
A supporting structure for a vibrator having a supporting member for supporting a prism-shaped vibrator, wherein said supporting member comprising:
- a straight linear intermediate portion being fixed to said vibrator and extending in a widthwide direction of said vibrator;
- two straight linear leg portions extending from both ends of said intermediate portion, a distance W' between tips thereof expanding wider than a length W of said intermediate portion;
- and
- a protective stopper provided in the vicinity of said supporting member for restricting displacement of said supporting member in the lengthwise direction of the vibrator.
A supporting structure for a vibrator having a supporting member for supporting a prism-shaped vibrator, wherein said supporting member comprising:
- a straight linear intermediate portion being fixed to said vibrator and extending in a widthwide direction of said vibrator;
- two straight linear leg portions extending from both ends of said intermediate portion, a distance W' between tips thereof expanding wider than a length W of said intermediate portion, wherein a ratio W'/W of the distance W' between said tips of said two leg portions of said supporting member and the length W of said intermediate portion of said supporting member is 1.5 or less;
- and
- a protective stopper provided in the vicinity of said supporting member for restricting displacement of said supporting member in the lengthwise direction of the vibrator.
