Abstract
A vibration device has a vibration member for exciting vibration by supplying power to the vibration device. A signal supply member for sandwiching the vibration member such that the vibration member can be elastically deformed supplies a driving electric signal to the vibration member.
Claims21
A vibration device comprising:
- a vibration member that generates a vibration therein in response to a driving electric signal applied to said vibration member;
- a contact member contactable with said vibration member, said contact member being movable relative to said vibration member by vibration generated in said vibration member;
- and
- a signal supply member that supports said vibration member and supplies a driving electric signal to said vibration member, said signal supply member comprising first and second cantilevered terminal contact portions, each of which sandwiches said vibration member at a supporting position of said vibration member such that said vibration member is elastically deformable by vibration generated in said vibration member.

A vibration device comprising:
- a case having an open side, first and second openings respectively located at opposite ends of said case, and an engaging portion disposed on an exterior portion of said case;
- a vibration member disposed in said case, said vibration member generating a vibration;
- a contact member inserted though the first and second openings of said case and supported relative to said case thereby, said contact member thereby being arranged in contact with said vibration member and linearly movable relative to said vibration member by vibration generated in said vibration member;
- and
- an urging member extended across the open side of said case and including a hook engaged with said engaging portion of said case, so that said urging member urges said vibration member and said contact member into pressure contact with each other at a location within said case.

A vibration device comprising:
- a vibration member that generates a vibration therein in response to a driving electric signal applied to said vibration member;
- a contact member contactable with said vibration member, said contact member being movable relative to said vibration member by vibration generated in said vibration member;
- and
- a signal supply member, composed of a conductive material, that supports said vibration member and supplies a driving electric signal to said vibration member, said signal supply member comprising first and second portions that sandwich said vibration member at supporting positions of said vibration member such that said vibration member is elastically deformable by vibration generated in said vibration member.

A vibration device comprising:
- a vibration member that generates a vibration therein in response to a driving electric signal applied to said vibration member;
- a contact member contactable with said vibration member, said contact member being movable relative to said vibration member by vibration generated in said vibration member;
- and
- a pair of opposing signal supply members that support said vibration member and supply respective driving electric signals to said vibration member, each signal supply member comprising a portion that sandwiches said vibration member at a supporting position of said vibration member such that said vibration member is elastically deformable by vibration generated in said vibration member.
