Publication number: 20120014535Abstract: The invention provides a sound collection device having little error in a desired directivity. The sound collection device includes a unidirectional microphone 12A, a unidirectional microphone 12B, and a unidirectional microphone 12C which are arranged on one plane. Each of the unidirectional microphones has the maximum sensitivity direction directed toward the inside of the arrangement. Each of the unidirectional microphones has a rear surface (direction of the minimum sensitivity) being open acoustically. Since the maximum sensitivity direction of each of the unidirectional microphones is directed toward the inside of the arrangement, the oscillation plane of each of the unidirectional microphones can be positioned substantially at the center of the arrangement. Thus, by adjusting the gain of the sound collected by the respective unidirectional microphones, the directivity can be freely formed on a flat plane with little error.Type: ApplicationFiled: December 16, 2009Publication date: January 19, 2012Applicant: YAMAHA CORPORATIONInventors: Ryo Oouchi, Yuichiro Suenaga, Satoshi Ukai, Seiichiro Hosoe

Publication number: 20110317862Abstract: A sound pickup apparatus, which can control directionality and has a simple structure, and in which a plurality of microphones can be provided so as to be floated by using the small number of parts, is provided. Three support columns 13A to 13C having the same length are provided upright on a top surface of a housing 11 of a sound pickup apparatus 1. The support columns 13A to 13C are equidistantly arranged away from a center position of the housing 11 and equally spaced 120 degrees apart from each other. A frame 4 having microphone frames 14A to 14C in which microphones are fitted is arranged above the top surface of the housing 11. In addition, the microphone frames 14A to 14C are coupled to the support columns 13A to 13C of the housing 11 by elastic rubbers 15A to 15C in a state where tensile stress passes the center of the housing 11 and is generated in an outward direction.Type: ApplicationFiled: February 10, 2010Publication date: December 29, 2011Applicant: YAMAHA CORPORATIONInventors: Seiichiro Hosoe, Yuichiro Suenaga, Satoshi Ukai, Ryo Oouchi

Patent number: 7196261Abstract: An electronic drum includes a pad to be beaten with sticks, a circular piezoelectric converter for converting stress to an electric signal and a semi-circular filter element adhered at one surface to the pad and at the other surface to the circular piezoelectric converter; the circular piezoelectric converter is partially held in contact with the semi-circular filter element and partially overhung under the pad; when the vibrations reach the filter element, the filter element eliminates high frequency vibration components from the vibrations, and transmits them to the half of the circular piezoelectric converter; the vibrations give rise to bending stress in the half of the piezoelectric converter held in contact with the filter element, and shake the other half of the piezoelectric converter; this results in enlargement of the bending stress, and the electric signal with a wide amplitude is taken out from the piezoelectric converter.Type: GrantFiled: March 28, 2003Date of Patent: March 27, 2007Assignee: Yamaha CorporationInventor: Yuichiro Suenaga

Patent number: 6784352Abstract: An acoustic drum or electronic percussion instrument is constructed by a drumhead corresponding to a punching sheet on which plenty of apertures are formed and a cylinder covered with the drumhead being stretched under tension as well as a muting structure which is realized by a vibration absorption member and a support structure containing L-shaped support members and a support plate. Herein, the support members are detachably attached to an interior periphery of the cylinder to support the support plate, on which the vibration absorption member is mounted and is arranged in contact with a backside surface of the drumhead to absorb vibration of the drumhead whose surface is being struck by a drumstick or else. Using the muting structure, it is possible to actualize mute performance in which drum sounds are being muted by reduction of the vibration of the drumhead propagating into the air.Type: GrantFiled: October 21, 2002Date of Patent: August 31, 2004Assignee: Yamaha CorporationInventor: Yuichiro Suenaga

Publication number: 20040025663Abstract: An electronic drum system includes an electronic drum having a shell, a drum head stretched across an opening of the shell, a vibration sensor converting vibrations of the drum head to an electric signal and a damper held in contact with the reverse surface of the drum head; when a drummer strikes the drum head with a stick, the drum head is shaken, and vibrations follow; the damper is held in contact with a certain area on the reverse surface, and the shake and vibrations are propagated from another area free from the damper to the vibration sensor; the shake is surely propagated to the vibration sensor, and the vibrations are rapidly decayed; for this reason, the vibration sensor exactly discriminates the shake from the peaks of the vibrations, thereby preventing an electronic sound generator from unintentionally repeated electronic beats.Type: ApplicationFiled: July 1, 2003Publication date: February 12, 2004Inventors: Minoru Harada, Yuichiro Suenaga
