# Noise-Making Mobile Protectors The Hoo Whistle Case is an Emergency Alert, Faster than Speed Dial By Amelia Roblin | Published 2013-04-02 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/hoo-whistle-case References: [yankodesign](http://www.yankodesign.com/2013/04/01/hoo-whistled/) & [whistlecase](http://www.whistlecase.com/) Think about how long it realistically takes you to input your key code on your mobile phone and either bring up your number pad and dial, or pull up your contacts and browse for someone specific. The low-tech Hoo Whistle Case would be a heaven-sent handset accessory in instances of danger, enabling you to broadcast a [help signal](https://www.trendhunter.com/trends/protechme) in a fraction of the time that it would take on your cell. Sang-Hoon Lee's clever product quite simply integrates a small mouthpiece, a chamber and a hole into an otherwise standard-looking [iPhone 5 case](https://www.trendhunter.com/trends/rhinoshield-airx). The wind passage thickens the profile slightly, but that curvature serves to make the [smartphone protector](https://www.trendhunter.com/trends/rugged-protective-case) more comfortable to hold in your palm. Made from polycarbonate in Korea, the Hoo Whistle Case comes in pink, white and black with other punchy colors in the interior. ## Trend Insights (Trend Hunter) - Score: 3.6/10 - Popularity: 49% | Activity: 51% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Gen Alpha, Millennial, Gen X - Top markets: North America, Europe, Asia ## 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 - **Emergency Alert Cases:** The Hoo Whistle Case demonstrates the potential for mobile phone cases to serve a dual purpose of protecting the phone, while also allowing users to easily call for help during emergencies. - **Quick Response Technology:** The Hoo Whistle Case highlights the potential for quick response technology that can save lives and prevent harm from dangerous situations. - **Integrated Safety Accessories:** The Hoo Whistle Case provides an example of how mobile phone cases can be designed to incorporate safety accessories that aid users in hazardous situations. ### Who This Affects Most - **Mobile Phone Accessories Industry:** The Hoo Whistle Case illustrates an opportunity for the mobile phone accessories industry to develop innovative safety features that may increase the appeal and functionality of their products. - **Personal Safety Industry:** The Hoo Whistle Case showcases the potential for personal safety industry to produce discreet and simple safety devices that can alert others to danger. - **Consumer Electronics Industry:** The Hoo Whistle Case illustrates how consumer electronics companies can incorporate safety features into popular products to meet consumer demands for safety and security. ## Related on Trend Hunter - [Anti-Theft Phone Cases](https://www.trendhunter.com/trends/unsnatchable-phone-case.md) - [Security-Enhancing Phone Cases](https://www.trendhunter.com/trends/cirotta-case.md) - [Phone Recovery Tools](https://www.trendhunter.com/trends/getmobi.md) - [Action Button Smartphone Cases](https://www.trendhunter.com/trends/bangcase.md) - [Topographical Relaxation Smartphone Cases](https://www.trendhunter.com/trends/ecue-case.md) - [Fashionable Inflated Phone Cases](https://www.trendhunter.com/trends/air-case-2.md) - [Sleek Smartphone-Inspired Flashlights](https://www.trendhunter.com/trends/whitt-flashlight.md) - [Emergency Distress Signals](https://www.trendhunter.com/trends/sos-light-app.md) - [Hyper-Cushioned Smartphone Cases](https://www.trendhunter.com/trends/hypercushionedsmartphone-case.md)
