# Pendulum Speakers The Bongue Amplifier Uses Kinetic Energy to Project Audio By Matt Ho | Published 2011-01-20 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/bongue-amplifier References: [mocoloco](http://mocoloco.com/archives/021157.php) & [studiotoer](http://www.studiotoer.com/) Studio Toer’s Bongue Amplifier isn’t your typical hi-tech state-of-the-art speakers available in stores. The Bongue Amplifier is a minimalist contraption in which the speaker is hung up on the wall with steel wires. The way sound is projected is through kinetic energy when you swing the arm. The audio signal then slowly amplifies through a descending counterweight. The Bongue Amplifier may require some effort to power, but it’s an interesting concept nonetheless. ## Trend Insights (Trend Hunter) - Score: 2.7/10 - Popularity: 4% | Activity: 69% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) > [Design](https://www.trendhunter.com/design) ## Key Themes ### What's Driving This Trend - **Minimalist Speakers:** The Bongue Amplifier showcases a minimalist design and challenges traditional speaker technology. - **Kinetic Energy Audio:** The use of kinetic energy to project sound offers a unique and potentially disruptive innovation opportunity in the audio industry. - **Effort-powered Speakers:** By requiring physical effort to power the speakers, the Bongue Amplifier introduces a new concept in the speaker market. ### Who This Affects Most - **Audio Technology:** The Bongue Amplifier presents a disruptive innovation opportunity in the audio technology industry. - **Home Decor:** The minimalist design of the Bongue Amplifier aligns with the growing trend for aesthetically pleasing home decor products. - **Green Energy:** The use of kinetic energy in the Bongue Amplifier aligns with the rising demand for sustainable and eco-friendly technologies in the green energy industry. ## Related on Trend Hunter - [Posh Power-Free Smartphone Speakers](https://www.trendhunter.com/trends/amplifying-speaker.md) - [Sculptural Audio Speakers](https://www.trendhunter.com/trends/loopen.md) - [Sculptural Gondola-Inspired Speakers](https://www.trendhunter.com/trends/gondola-bluetooth-speaker.md) - [Vibrational Full-Range Speakers](https://www.trendhunter.com/trends/gadol-vibration-speaker.md) - [Sand-Made Kinetic Speakers](https://www.trendhunter.com/trends/econik-1851.md) - [Resonance-Powered Portable Speakers](https://www.trendhunter.com/trends/leapsonic-speaker.md) - [Stylish Low-Tech Sound Systems](https://www.trendhunter.com/trends/frame-sound.md) - [Distortion-Free Sound Systems](https://www.trendhunter.com/trends/genesis-speaker.md) - [Ceiling-Mounted Orb Speaker Concepts](https://www.trendhunter.com/trends/andr-terchanian.md)
