| 20090100984 | Special Resonant Side Drumhead for Live and Studio Miking Applications - The resonant drum head mounted speaker cone apparatus improves the sound of the drum on audio recordings and in live sound situations and changes the way the drum is miked in live and studio applications. By integrating the resonant side drumhead with a speaker cone, when the drum is hit (on the batter head), the air pressure generated inside the drum moves the opposite resonant head. The center of the resonant drumhead is cut out and a speaker cone with the dust cap is glued to the inside thereof facing outwards. The speaker cone, which also vibrates from this pressure, now becomes the miked surface of the instrument as opposed to previously having to mike the drum from above the respective batter heads where it often interferes with the player. Using otherwise conventional miking techniques, a wider range of attack and tone characteristics can be obtained from the drumhead. Additionally, use of optional speaker cone sizing, speaker and dust cap composition options and dust cap sound holes also contribute to define the sound characteristics based on end user preference. | 04-23-2009 |
| 20090241754 | DRUM PAD AND MANUFACTURING METHOD THEREOF - A drum pad has a knitted material that is strechable and has a top surface to be beaten by a stick and a rear surface opposite to the top surface, a resin member that is strechable and thinner than the knitted material and that is capable of being thermally fused and bonded to the knitted material, and a rubber. The drum pad is formed of a first layer portion, a second layer portion, and a body portion. The first layer portion is formed in a region of the knitted material including the top surface thereof but not including the rear surface, and is permeated with the melted resin member such that the resin member and the knitted material monolithically solidify with each other. The body portion is formed of the rubber. The second layer portion is formed in a remaining region of the kitted material other than the first layer portion and formed between the body portion and the first layer portion, the second layer portion being impregnated with the rubber such that the body portion is bonded to the rear surface of the knitted material. | 10-01-2009 |

| 20100175535 | Percussion resonance system - The percussion resonance system allows a drummer to produce additional, resonant acoustic effects beyond those produced by a conventional drum or other percussion instrument. In one embodiment, the percussion resonance system includes a substantially cylindrical sidewall having opposed upper and lower open ends, similar to the sidewall of a conventional drum, and batter and resonant heads respectively covering the upper and lower ends of the substantially cylindrical sidewall. A plurality of apertures are formed through either the batter head, the resonant head, or both, in order to produce additional acoustic effects caused by the air passing through the apertures as the heads vibrate. Air passing through the apertures increases the overall tonal qualities of the percussion instrument, and further aids in decreasing generation of unwanted vibrations, particularly in the form of ringing sounds or overtones. Further embodiments include inserts for percussion instruments having surfaces with similar apertures formed therethrough. | 07-15-2010 |
| 20110030529 | EXTENDED LOW FREQUENCY RESONANT STRUCTURE FOR DRUMHEAD - A drum fitted with drum heads features easy adjustment and variation of low-pitched sound. The drum head is formed with one or more openings to which surrounds made of material the same as or different than the drum head itself is attached for an independent and localized vibration area. Alternatively, the drum head is formed with a successively corrugated local area that offers localized deformation of the drum head. Either one of the constructions of the drum head provides the drum head with an independent and resiliently deformable local surface whereby when the drum is struck, the air contained inside the drum is pressurized to cause the vibration of the independent local surface, effectively increasing the vibration amplitude of the local surface on the drum head and thus extending the sound of the drum to a lower level. | 02-10-2011 |
| 20110048212 | Aroma drumhead - A musical drumhead having a top surface and bottom surface and a means attached to the drumhead for discharging an aromatic vapor. The musical drumhead is comprised of a membrane having means to vent the aromatic vapors through the top surface of the drumhead and disperse the vapors into the surrounding environment. Vent means comprises a plurality of vent holes in the drumhead membrane through which the vapors are discharged. The primary source of the vapors is a pad of porous material impregnated with an aroma producing liquid with a pleasing fragrance. The pad of porous material is attached in some conventional manner to the bottom surface of the drumhead immediately beneath the vent holes. The striking of the drumhead produces a vibration in the drumhead membrane which, in turn, excites the molecules in the air beneath and above the membrane. The aromatic oil vapors gathered around the impregnated pad are initially forced in all directions by the excited air and then dispersed through the vent holes into the surrounding areas. | 03-03-2011 |
