Articulated Mini Guitar Amplifier for Portable Sound Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electric guitar amplifier and speaker systems are bulky, heavy, and difficult to move, limiting guitarist mobility and requiring extensive planning and personnel to set up, especially for playing at remote locations.
Innovation Solution
A portable and miniature amplifier speaker system directly attaches to an electric guitar via a male plug and includes a speaker that can be articulated for directional sound emission, with stabilizer arms to protect the guitar from damage and ensure balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional amplifier and speaker systems are used, then sound amplification quality is maintained, but the system becomes bulky and heavy, limiting mobility
Solution Approach 1:
The patent divides the traditional amplifier-speaker system into a miniature unit that attaches directly to the guitar body, separating it from the need for large external equipment. This segmentation enables the guitar to function as its own amplifier platform, dramatically reducing the weight of movable equipment while maintaining sound quality through direct coupling of the speaker to the instrument.
Solution Approach 2:
The patent merges the amplifier and speaker components into an integrated unit that attaches to the guitar body, combining functions that were previously separate (guitar as instrument, amplifier as external device). This merging eliminates the need for heavy external equipment while preserving sound amplification quality through direct integration.
2Ease of operation
If traditional heavy amplifiers are moved to remote locations, then playing mobility is achieved, but extensive planning and personnel are required
Solution Approach 1:
The patent creates a dynamic system where the amplifier unit is permanently attached to the guitar, transforming it from a static heavy equipment setup to a mobile integrated system. This dynamic configuration allows the guitarist to move freely to any location without the need for advance planning, as the amplifier travels with the instrument.
Solution Approach 2:
The patent implements self-service by making the guitar itself the amplifier platform. The guitar body houses the amplifier and speaker components, eliminating the need for external equipment that would require setup and transport by multiple people. The system serves itself, with no additional personnel or planning required for mobility.
3Ease of operation
If a miniature amplifier is directly attached to the guitar, then mobility is improved, but the guitar may be damaged by the attached equipment
Solution Approach 1:
The patent applies beforehand cushioning by incorporating protective elements into the design of the attached amplifier unit. The housing and mounting structure are designed to protect the guitar body from damage, and protective coverings are provided for the speaker and electronic components. This prior protection prevents damage while maintaining the portability benefits of the integrated system.
4Adaptability or versatility
If the speaker is fixed in position, then the structure is simple, but sound cannot be directed toward the audience
Solution Approach 1:
The patent applies dynamics by making the speaker position adjustable rather than fixed. The speaker can be rotated and positioned to direct sound toward the audience, transforming the system from a static configuration to a dynamic one that adapts to different performance needs. This dynamic positioning capability provides versatility without requiring complex mechanical structures.

AI summary
A portable miniature sound amplifying apparatus for use with an electric guitar having a guitar jack, includes a body, an electric sound amplifying device positioned in the interior space of the body, and a guitar plug in electrical communication with the electric sound amplifying device that includes a male configuration for selectively mating with the guitar jack of the electric guitar. A speaker is mounted to the electric sound amplifying device and may be directionally articulated and is configured to receive and emit sound data from the guitar via the guitar plug. One or more stabilizer arms may be pivotally coupled to the sound amplifying device and positioned to protect a guitar from being damaged thereby.
