Hybrid Drum Integrating Djembe for Deep Bass Resonance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing percussion instruments like the cajon lack the ability to produce a deep bass with resonance similar to conical or elongated drumheads while maintaining the design and benefits of a cajon, such as portability and the ability to be played while seated, and require multiple instruments to achieve a variety of sounds.
Innovation Solution
A hybrid drum that integrates a six-sided box drum with another type of drum, such as a djembe, allowing for deeper bass and treble sounds, with the djembe's drumhead and the box drum's strike surface in close proximity for easy access and striking, and the option to interchange other elongated drums or snare drums, providing a compact and portable unit that reduces the need for multiple instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cajon is used, then portability and seated playing capability are maintained, but deep bass resonance similar to conical or elongated drums cannot be produced
Solution Approach 1:
The patent combines a cajon body with a conical or elongated drum inserted into its interior space. The drum is positioned within the cajon's resonant chamber, allowing both instruments to function together as a single hybrid instrument. This merging enables the player to access both the cajon's characteristic sounds and the deeper bass resonance of the conical/elongated drum without requiring separate instruments.
Solution Approach 2:
The conical or elongated drum is nested inside the cajon body, with the drum's base resting on the cajon's bottom panel and its sides extending upward within the resonant chamber. This nesting arrangement allows the smaller drum to be contained within the larger cajon structure, maximizing space utilization while maintaining both instruments' functional characteristics.
2Adaptability or versatility
If multiple separate drums are used to achieve diverse sounds, then sound variety is improved, but performance space and number of players required increases
Solution Approach 1:
The hybrid drum integrates multiple percussion capabilities into a single instrument body. The conical or elongated drum provides deep bass and resonant tones, while the cajon's front panel with snares and strike surfaces provides crisp percussive sounds. This combination allows one player to produce diverse percussion sounds from a single instrument, eliminating the need for multiple separate drums and reducing performance space requirements.
3Shape
If a conical or elongated drum is used, then deep bass resonance is produced, but portability and seated playing capability are lost
Solution Approach 1:
The patent merges the conical or elongated drum shape (which provides deep bass resonance) with the cajon's box structure (which enables seated playing). The hybrid instrument maintains the cajon's horizontal orientation and top surface for seating, while the inserted conical/elongated drum provides the desired bass resonance. This combination preserves the ease of operation and portability of the cajon while adding the acoustic properties of the conical/elongated drum.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hybrid drum offers a compact, portable solution that produces a range of percussion sounds, including deeper bass and treble, while retaining the crisp sounds of the cajon, requiring less performance space and fewer players than traditional setups, and allowing for quick and effective combination of sounds.
Implementation Method 1
A typical cajon has a resonant chamber enclosed by the cajon walls or panels, with an opening or port formed in the back panel for producing bass tones from the resonant chamber
Implementation Method 2
The cajon walls or panels, because they are relatively thin, operate as vibrating membranes serving the same relative function as a conventional drumhead

AI summary
A hybrid drum apparatus combines and integrates at least two different types of drums into a common apparatus. The hybrid drum apparatus includes a six-sided box drum upon which a player sits and strikes the front and side surfaces to produce various percussion sounds. The box drum body serves as a housing for another type of drum, such as a djembe, which is an elongated goblet-shaped hollow drum, having a membrane drumhead top. The djembe is integrated into the box drum body such both may be played simultaneously. The hybrid drum provides an opening into which the djembe may be inserted such that the drumhead is relatively flush with the strike surface of the box drum. The rear panel of the box drum is provided with an opening which both supports the bottom end of the djembe and allows for the sounds produced to resonate out from the box drum body. The hybrid drum apparatus may incorporate other elongated drums, such as a doumbek or congo, as well as frame drums, such as a flat drum or tambourine. Advantageously, the hybrid drum apparatus may combine and support a variety of drums interchangeably.
