This speaker makes use of [empty bottles and containers](https://www.trendhunter.com/trends/anew), turning them into [eco-friendly sound systems](https://www.trendhunter.com/trends/maker-hardware-ttd3000). 'Green Voice' was designed by Nien-An Lin, Ya-Fang Cheng and Genius KYE Systems Corp, and is made out of biodegradable material. What I find most interesting about 'Green Voice' is its battery. The battery is said to be a "paper battery," which both intrigues and confuses me. Either way, I can't wait for the day when my empty water bottle can also double as a speaker. No more refills for me. ## Trend Insights (Trend Hunter) - Score: 1.5/10 - Popularity: 23% | Activity: 15% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### What Makes This Trend Stand Out - **Upcycled Speakers:** Opportunity for companies to create eco-friendly sound systems by repurposing waste materials like empty bottles. - **Biodegradable Technology:** Potential for innovations in biodegradable batteries, like 'Green Voice's' paper battery, to create more sustainable electronic devices. - **Sustainable Audio Solutions:** Demand for eco-friendly sound systems that utilize renewable materials and energy sources, presenting opportunities for companies to develop innovative products. ### Sectors Adopting This - **Consumer Electronics:** Consumer electronics companies can explore upcycling as a design strategy for developing eco-friendly and unique audio products. - **Sustainable Packaging:** The packaging industry can collaborate with electronics companies to repurpose empty containers and bottles into functional speakers, promoting sustainability. - **Renewable Energy:** The renewable energy sector can be involved in creating more efficient and sustainable power sources for eco-friendly sound systems, like biodegradable batteries. ## Related on Trend Hunter - [Recycled Waste Speakers](https://www.trendhunter.com/trends/gomi.md) - [Wine Bottle-Resembling Speakers](https://www.trendhunter.com/trends/dream-echo.md) - [Recycled Plastic Portable Speakers](https://www.trendhunter.com/trends/recycled-plastic-portable-speakers.md) - [Posh Power-Free Smartphone Speakers](https://www.trendhunter.com/trends/amplifying-speaker.md) - [Nature-Inspired Multifunctional Speakers](https://www.trendhunter.com/trends/moss-echo.md) - [Renewable Material Speakers](https://www.trendhunter.com/trends/house-of-marley-get-together.md) - [Eco-Friendly Art Frame Speakers](https://www.trendhunter.com/trends/vavia.md) - [Eco‑modular Audio Speakers](https://www.trendhunter.com/trends/mynd-speaker.md) - [Speaker-Equipped Flower Vases](https://www.trendhunter.com/trends/blooming-product.md)
