Guitar-Mounted Portable Speaker With Stable Strap-Button Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric string instruments face portability issues due to the need for separate amplifiers and speakers, which are bulky and require a power source, and retrofitting with built-in speakers is costly and alters the instrument's integrity, limiting mobility and flexibility for users.
Innovation Solution
A portable speaker system with a housing, amplifier, and speaker that attaches to an electric string instrument via a button connector and stabilizer, allowing for wireless or wired connectivity with a computing device for audio processing and supplementary audio, enabling users to play their preferred instrument without being tethered to a separate speaker system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a separate amplifier and speaker system is used for electric string instruments, then audio output quality is improved, but portability deteriorates due to large size and power source requirements
Solution Approach 1:
The patent combines the amplifier, speaker, and power supply into a single integrated portable unit that attaches to the electric string instrument. This merging of previously separate components (amplifier, speaker, power source) into one compact system resolves the contradiction by maintaining audio output quality while dramatically improving portability and eliminating the need for separate equipment.
Solution Approach 2:
The portable speaker system serves multiple functions: it amplifies the instrument signal, provides wireless connectivity for music playback, offers audio processing effects, and includes a rechargeable power supply. This multi-functionality allows a single device to replace multiple separate pieces of equipment, improving portability while maintaining comprehensive audio capabilities.
2Ease of operation
If built-in speakers are installed in the electric string instrument, then portability is improved, but instrument integrity deteriorates due to costly and burdensome retrofitting
Solution Approach 1:
Instead of integrating speakers directly into the instrument body, the patent segments the audio system into a separate portable unit that attaches to the instrument via a strap button. This segmentation preserves the original instrument integrity while achieving portability, as the instrument itself remains unmodified and the speaker system can be easily attached or removed.
Solution Approach 2:
The portable speaker system acts as an intermediary between the electric string instrument and the user's ear. It receives the instrument signal through a standard output jack, processes and amplifies it, and delivers the sound through its own speaker. This intermediary approach avoids direct modification of the instrument while maintaining audio quality and portability.
3Adaptability or versatility
If a portable computing device is used for supplementary audio or processing, then audio functionality is improved, but portability deteriorates due to multiple connected devices
Solution Approach 1:
The patent merges the portable computing device's audio processing capabilities with the speaker system into a single integrated unit. The portable speaker system includes wireless connectivity (Bluetooth, Wi-Fi) that allows it to receive and process music files and audio effects without requiring a separate computing device, thereby maintaining enhanced audio functionality while improving portability by eliminating the need for multiple connected devices.
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 portable speaker system enhances the mobility of electric string instruments by providing an integrated, compact solution that allows users to play their preferred instruments while adding audio processing capabilities without altering the instrument's original form, thus improving portability and usability.
Implementation Method 1
an amplifier coupled to the audio jack and configured to receive an audio signal and amplify the audio signal to generate an amplified audio signal
Implementation Method 2
a speaker coupled to the amplifier and configured to receive the amplified audio signal and generate output sound from the amplified audio signal
Data Source
AI summary
A portable speaker system for an electric string instrument such as a guitar. The portable speaker system has a housing including an audio jack for receiving a raw audio signal from a guitar, an amplifier, a speaker, and a power supply. The portable speaker system attaches to the guitar by a button connector which releasably attaches to a strap button of the guitar, and a stabilizer for inhibiting rotation of the portable speaker system when attached to the guitar. The portable speaker system portably generates output sound from the raw audio signal. The portable speaker system can couple with a portable computing device, which can process the raw audio signal and provide a supplementary audio signal, from which the portable speaker system can portably generate output sound.
