195 results about "Drumhead" patented technology

A drumhead or drum skin is a membrane stretched over one or both of the open ends of a drum. The drumhead is struck with sticks, mallets, or hands, so that it vibrates and the sound resonates through the drum.

Drum mounting and tuning system providing unhindered and isolated resonance

InactiveUS8629340B1Reducing and completely isolating same energyUndesired distortionPercussion musical instrumentsResonanceEngineering
Some embodiments provide a drum structural framework comprising a top shell mount, bottom shell mount, rod holders, and tension rods. The top shell mount and bottom shell mount are mounted to either ending edge of a drum shell disposed between the two mounts. A first set of the rod holders are coupled to the top shell mount and an aligned second set of the rod holders are coupled to the bottom shell mount. The tension rods link the two sets of rod holders without hindering resonance of the drum shell. Tuning assemblies on the rod holders adjust the distance separating the top shell mount from the bottom shell mount, thereby controlling the force imposed on the drum shell. Each rod holder includes one or more dampeners that isolate energy passing from the drumhead to the shell from also reverberating throughout the structural framework of the tension rods and rod holders.

Bass drum

A bass drum 10 has a hollow cylindrical shell 11, a drumhead 12 mounted on an opening end of the shell 11 to form a striking surface, and a striking surface attachment 13 provided on the reverse side of the drumhead 12. The striking surface attachment 13 is formed of an elastic sheet. At least a part of an outer area of the striking surface attachment 13 is fixed to the drumhead 12 and a central area of the striking surface attachment 13 is not fixed to the drumhead 12. As a result, the bass drum 10 can generate a struck sound having both deep bass sound and clear attack.

Snare drum adjustable dampening device

InactiveUS7151211B2Suppress soundDampening the sounds produced by the drumheadPercussion musical instrumentsDrumheadElectric wire
A device for dampening sounds produced by a drumhead of a musical drum having a drumshell comprising a frame assembly having a first elongated bar member with a first channel and a second elongated bar member with a second channel. The two bar members are disposed in opposed spaced apart parallel relation. Mounting brackets are affixed and secured to the two bar members at their opposing ends. Attached, respectively, to the two mounting brackets between the two bar members are the opposing ends of an assembly of snare wires. The mounting brackets are also provided to connect the assembly to the drumshell and are vertically adjustable between a high tension position such that the snare wires are moved to press against the drumhead and a lower tension position in which the wires are caused to relax to enable the release of tension of the wires against the drumhead. The dampening member has end components adapted to fit slidably into the first and second channels, respectively, to enable the dampening member to be movable between the two elongated bar members along the frame assembly in physical contact with the snare wires to adjust the tension of the wires against the drumhead to produce a variety of sounds. The dampening member is comprised of a base member, a device for physically contacting the snare wires as it is moved along the frame assembly and a resilient material situated between the base member and the contact device to buffer vibrations produced by the struck drumhead.

Background audio determination method and device, video editing method and device and computer equipment

The invention relates to a background audio determination method and device, a video editing method and device and computer equipment. The background audio determination method comprises the steps that a content time length sequence corresponding to target content is acquired, wherein the playing time length of content segments of the target content form the content time length sequence accordingto a content playing sequence; a drumbeat time interval sequence corresponding to each candidate audio is acquired, wherein the interval lengths between the drumheads in each candidate audio forms a corresponding drumhead time interval sequence according to the sequence of the drumheads in the candidate audio; target similarity between the content time length sequence and the drumhead time interval sequence corresponding to each candidate audio is acquired; and background audio corresponding to the target content is determined from a candidate audio set according to the target similarity corresponding to the candidate audios. Background audio recommendation can also be performed through the target similarity and a recommendation model based on artificial intelligence. By adopting the method, the matching degree of audio selection can be improved.
