# Expandable Stick-On Speakers The 'BumpOut' Smartphone Speaker Has an Expanding Resonance Chamber By Michael Hemsworth | Published 2016-12-19 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/phone-speaker References: [yankodesign](http://www.yankodesign.com/2016/12/19/bumpout-innovative-portable-speaker/) & [indiegogo](https://www.indiegogo.com/projects/bumpout-small-speaker-big-sound-bigger-mission-audio) Thinner and lighter smartphones are easier to carry but render the sound quality capable from the built-in speaker to be quite weak, so the 'BumpOut' smartphone speaker is intended to help curb this issue. The 'BumpOut' speaker features a stick-on design that can be placed on the rear of a smartphone, onto a laptop or stuck virtually anywhere one wishes. When utilized, the 'BumpOut' will instantly go to work to pump out tunes at a much better level than what's possible with the built-in speaker on your smartphone. This is because the 'BumpOut' smartphone speaker features an expanding resonance chamber that pops out when it's in use. This means the sound can resonate better to provide a louder experience without requiring oversized equipment. ## Trend Insights (Trend Hunter) - Score: 4.2/10 - Popularity: 63% | Activity: 56% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### What Makes This Trend Stand Out - **Stick-on Speakers:** Stick-on portable speakers that can be attached to any surface to provide better sound quality. - **Expanding Resonance Chambers:** Smartphone and laptop speakers with resonance chambers that expand to improve sound quality and loudness. - **Slim Audio Accessories:** Portable audio accessories that are slim, lightweight, and easy to carry around. ### Sectors Adopting This - **Consumer Electronics:** The consumer electronics industry can innovate and expand the market for slim audio accessories. - **Mobile Devices:** The mobile device industry can partner with Speaker manufacturers to bring better sound quality to mobile devices. - **Gaming:** Game accessory makers can integrate slim audio accessories with gaming devices to bring better immersive sound to games. ## Related on Trend Hunter - [Compact Phone Speakers](https://www.trendhunter.com/trends/thinn.md) - [Modular Audio Immersion Speakers](https://www.trendhunter.com/trends/takeout-speaker.md) - [Resonance-Powered Portable Speakers](https://www.trendhunter.com/trends/leapsonic-speaker.md) - [Portable Phone-Attached Mini Speakers](https://www.trendhunter.com/trends/magboom-mini.md) - [Phone Charger-Infused Speakers](https://www.trendhunter.com/trends/phone-chargerinfused-speaker.md) - [Vibrating Wearable Speakers](https://www.trendhunter.com/trends/xiaomi-wearable-speaker.md) - [Speaker-Centric Smartphones](https://www.trendhunter.com/trends/music-phone.md) - [Vibrational Full-Range Speakers](https://www.trendhunter.com/trends/gadol-vibration-speaker.md) - [Freestanding Smartphone Dock Speakers](https://www.trendhunter.com/trends/jteman-phone-stand-and-speaker.md)
