Introduction:
Portable sound amplification devices are increasingly used for education, entertainment, and communication. However, many conventional speakers require electricity, involve higher costs, and contribute to electronic waste. This project introduces SoundForge, an innovative sound-enhancing device designed using simple and accessible materials to provide an alternative audio amplification solution.

Problem Statement:
Many users need louder and clearer sound output from mobile devices in situations where electronic speakers are unavailable, expensive, or impractical. In addition, plastic waste remains a growing environmental concern, creating a need for creative recycling solutions that transform waste materials into functional products.

Solution:
SoundForge was developed as a low-cost sound amplification device using repurposed plastic materials and a simple structural design to enhance sound output without external power. The device works by directing and amplifying audio waves from a mobile source through its shaped chamber, improving sound projection while promoting sustainable material reuse.

Impacts:
The innovation provides an affordable and eco-friendly sound amplification option for students and general users. It promotes waste reduction through recycling, encourages creative engineering design, and demonstrates how simple materials can be transformed into useful functional products. The project also supports environmental awareness and practical STEM learning.

Commercialization Potential:
SoundForge has potential for commercialization as a low-cost educational, eco-friendly, and portable sound accessory. It can be produced using recycled materials with minimal manufacturing cost and marketed to schools, environmentally conscious consumers, and communities seeking sustainable everyday innovations. Its simple design also offers opportunities for product customization and small-scale business development.
