Constricted Sound Systems

The Bang & Olufsen A4 Speakers Emit Music Only for the Listener

— April 13, 2013 — Unique
There are a few fascinating features to the Bang & Olufsen A4 Speakers that make them a great improvement upon existing sound systems. Designed as a concept by Clément Puertolas, the devices have been engineered for increased convenience and sound pollution reduction.

Taking a flaring cylindrical form, each gadget is accented with a larger wooden ring that brings stability to it as it sits and provides a handle for easy portability. Because they are cordless, the amplifiers can be carried throughout the house, connecting to your smartphone, your tablet and your computer wirelessly.

Dome-shaped components within the Bang & Olufsen A4 Speakers project sound by focused parabolic reverberation and controlled diffusion, lessening the distance that your music travels. The devices are designed to be used up close and recharged effortlessly while resting on an induction panel.
Trend Themes
1. Cordless Sound Systems - The popularity of wireless and portable sound systems provides an opportunity for companies to create cordless sound systems that can be carried throughout the house.
2. Controlled Diffusion Speakers - Developing dome-shaped components that project sound by controlled diffusion lessens the distance that the music travels and creates opportunities for designers to create more efficient and high-quality sound systems.
3. Induction Charging Panels - The use of induction charging panels can make charging electronic gadgets effortless and presents an opportunity for companies to integrate this technology into other products and appliances such as furniture and lighting fixtures.
Industry Implications
1. Consumer Electronics - Companies in the consumer electronics industry can take advantage of the trend towards cordless and portable sound systems by developing new lines of headphones and wireless speakers.
2. Furniture Design - Furniture designers can incorporate induction charging panels into their products such as coffee tables, nightstands and shelves for convenience and a unique selling point.
3. Interior Design - Interior designers can utilize the controlled diffusion speaker technology in the design of movie rooms, home theaters, and audio-enabled living spaces to ensure an optimal listening experience even in smaller spaces.
