Abstract
An acoustic transducer includes a ring oscillator. The ring oscillator includes: a first cushioning material; a pair of first and second annular members that are laminated in an axial direction thereof with the first cushioning material therebetween, each of the annular members having first and second ends in a circumferential direction thereof, and a notch portion formed between the first and second end; a first connecting portion that connects the first end of the first annular member and the second end of the second annular member; and a second connecting portion that connects the second end of the first annular member and the first end of the second annular member.

An acoustic transducer comprising a ring oscillator, the ring oscillator comprising:
- a first cushioning material;
- a pair of first and second annular members that are laminated in an axial direction thereof with the first cushioning material therebetween, each of the annular members having first and second ends in a circumferential direction thereof, and a notch portion formed between the first and second ends;
- a first connecting portion that connects the first end of the first annular member and the second end of the second annular member;
- and
- a second connecting portion that connects the second end of the first annular member and the first end of the second annular member,
- the first and second connecting portions being separate from each other,
- the first and second connecting portions being laminated to each other in the axial direction.
An acoustic transducer comprising a ring oscillator, the ring oscillator comprising:
- a plurality of first cushioning materials;
- a plurality of annular members that are laminated in an axial direction thereof with the first cushioning materials therebetween, each of the annular members having first and second ends in a circumferential direction thereof, and a notch portion formed between the first and second ends, the annular members including a first annular member provided at a top end in the axial direction, a second annular member provided at a bottom end in the axial direction, a third annular member adjacent to the first annular member in the axial direction;
- and
- a plurality of connecting portions which include first and second connecting portions, the first connecting portion connecting the first end of the first annular member and the second end of the second annular member, the second connecting portion connecting the second end of the first annular member and the first end of the third annular member,
- the first and second connecting portions being separate from each other,
- the first and second connecting portions being laminated to each other in the axial direction.
