연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An attachment part is disposed on a part of the edge of a resonance plate, which is made of a metal containing copper, and a weight is attached to the resonance plate at a predetermined distance from the attachment part. Plural vibration pickups are attached to the surface of the resonance plate between the weight and the attachment part. The resonance plate is attached to a percussion instrument at the attachment part. The plural vibration pickups produce electric signals corresponding to the resonant vibrations at their respective positions on the reso...

The percussion-instrument pickup according to claim 1, wherein said hitting surface is substantially circular in shape, said resonance plate has a substantially rectangular shape, the longer side thereof being shorter than the diameter of the hitting surface of the percussion instrument to which the percussion-instrument pickup is attached, the weight part being attached to one of the shorter sides thereof, and the attachment part being disposed at the other shorter side, and the plurality of vibration pickups are attached to the surface of said resonance plate between the attachment part and the point of attachment of the weight part. 3. The percussion-instrument pickup according to claim 1, wherein said resonance plate has one or more notches formed in an edge thereof, the one or more notches divide said resonance plate into a plurality of resonance elements, and each of the plurality of resonance elements has a vibration pickup attached thereto. 4. The percussion-instrument pickup according to claim 2, wherein said resonance plate has one or more notches formed in an edge thereof, the one or more notches divide said resonance plate into a plurality of resonance elements, and each of the plurality of resonance elements has a vibration pickup attached thereto. 5. An electric percussion instrument that comprises cylindrical body and a drumhead attached over an open end of the cylindrical body and produces a drum sound when the drumhead is hit, wherein the electric percussion instrument further comprises a percussion-instrument pickup that has a resonance plate that is made of a metal containing at least copper and has an area smaller than that of said drumhead, a weight part attached to a part of the perimeter of the resonance plate, said weight part having a volume of material separate from said resonance plate, an attachment part disposed at a predetermined distance from the point of attachment of the weight part, and a plurality of vibration pickups attached to the surface of said resonance plate between said attachment part and said weight part, and said resonance plate of said percussion-instrument pickup is attached to the inner wall of said body via said attachment part in a cantilever configuration, said resonance plate is disposed inside said drumhead, said weight part and said vibration pickups disposed inside said drumhead and spaced apart therefrom, said resonance plate supported in the cantilever configuration is excited by a vibration of said body, a resonance frequency of said resonance plate depends on a weight of said weight part, and said vibration pickups attached to said resonance plate produce drum-sound signals from the resonance of said resonance plate. 6.
