- Dyson's original Air Multiplier, released in 2009, was the first fan to use brand new blade-less technology.
- Do we people know it ? No, that got some of its quiet reasons.
- This revolutionary technology was Invented almost by chance and its totally different from our conventional fans we use in our daily life which chops the air with its high speed blades,this new technology sucks air Instead, airflow came from the base was amplified in a loop before being pushed outwards a concentrated area. With no blades chopping through air, and it is also said that this fan produced a smoother, quieter breeze but not actually it does.
- Revolutionary as the product was, it didn't stand too long as the design as believed was not as quieter as it was promised . so the company had a hard time to redesign this and this as a major concern the designers had gone with many hurdles and finally produced a revolutionary new Air Multiplier which is promised to be 75% quieter than the first generation.
- To get there, Dyson’s engineers deconstructed the original blade-less technology. In the process of silencing the design, they came across the principle of the Helmholtz cavity. It sounds new right? Actually it's very old principle
- In a Helmholtz cavity, also called a Helmholtz resonator, sound gets reflected through hard, curved surfaces. The phenomenon explains why holding a seashell to your ear will produce a breathy, whirring sound, or why blowing air across a glass bottle top makes a hum. Noise is created through the Helmholtz resonator principle, but more importantly what I want to explain is noise can be meticulously controlled.
- “It’s a classic way of addressing this sort of issue,” Baptiste tells Co.Design.
- “ and this principle was also been using every day in our life ,You can find them in car exhaust systems. Almost every car has this sort of silencer to attenuate the noise. And this technology is used in building acoustics, for structures like concert halls.
- Previously with the Air Multipliers, the motar was pulling or sucking the air in and releasing it
- The designers say that the actual problem with the first design was the air was not controlled or guided and thus leading it to be noisey
- For this the engineers had carefully calculated and designed the new concept with a revolutionary design that mimic helmhots principle and making it quiter
- As I mentioned you that this was not very well recognized as the price for this beautiful and 2nd generation concept was very high for a middle class employee.
- However ,this was an beautiful attempt as it was safety with no-blades and beautiful with its design and efficient with its technology and the thing that itz costlier will definitely screw this design
- As I always say sharing is careing please do share this new concept with your loved ones.
- Any thing got to say ?
