On March 30, Dyson officially released the Dyson Zone air purification headset, which is also Dyson's first entry into the wearable device field. In addition to air purification, the new product also supports active noise reduction technology, which can solve the problem of urban air quality and noise pollution at the same time.
In a communication with Dyson engineers, he told Titanium Media App that after Dyson launched the first bladeless fan in 2009, engineers shifted the focus of research and development from the flow of a single air to the use of clean air to heat up or cool down the room. Dyson launched its first purification fan in 2015 and has since developed technologies such as formaldehyde removal, clean humidification and hePA filtration.
Dyson Zone air purification headphones will be Dyson's next focus and the first step in Dyson's entry into wearables and audio, providing users with high-quality filtering performance anytime, anywhere.
According to Dyson engineers, dyson Zone air purification headphones have spent 6 years on research and development, during which more than 500 prototypes have been designed, unlike regular masks, it is equipped with high-performance filters and two small air pumps, which can deliver clean air without touching the face. The headset supports 4 air purification modes: low-speed mode, medium-speed mode, high-speed mode and automatic mode.
Since different exercise levels produce different breathing modes, Dyson Zone air purification headphones are equipped with an acceleration detector, in automatic mode, its purification speed can be automatically adjusted between high speed, medium speed, low speed, in addition, after the mask is removed, the product can also be used as an ordinary active noise reduction headphones.
Specific to the configuration, there is a compressor in each earcup on both sides of the headset to draw air into the double-layer filter, and the motor that provides power for the compressor is currently the smallest of all Dyson products, and it is also one of the difficulties in the development of Dyson Zone air purification headphones. In addition to being responsible for inhaling air, the two motors lower two purified air streams through the contactless mask to the wearer's nose and mouth.
This non-contact airflow delivery method is also one of the core technologies of the Dyson Zone air purification headphones, and to do this, it is first necessary to optimize the geometry and curvature of the mask, as well as the central grid that transports the two air streams, together to ensure that the filtered clean air can be effectively delivered to the wearer's nose and mouth in the crosswind environment.
Lacking existing test methods, Dyson engineers also developed a simulated human breathing model called "Frank," which is equipped with mechanical lungs and sensing devices. Frank could 'inhale' pollutants by simulating human breathing patterns in a control chamber, and engineers would then measure pollution levels at Frank's nasopharynx to determine how efficiently the product was filtering out particulate matter that would otherwise end up in Frank's artificial lung.
In terms of filtration technology, the filter of the Dyson Zone air purification headphones uses a double-layer structure, in which a negatively charged electrostatic filter media can capture ultrafine particles such as allergens, as well as particles generated during traffic roads, industrial combustion and building construction. Another layer of potassium-rich carbon filters captures urban gaseous pollutants such as nitrogen dioxide (NO2) and sulfur dioxide (SO2).
At the same time, in order to isolate noise and improve sound performance, Dyson Zone air purification headphones are also equipped with ANC active noise reduction technology, supporting 3 active noise reduction modes, and in terms of sound tuning, Dyson engineers said that the new product will focus on low distortion and neutral frequency response.
In terms of wearing, as Dyson's first wearable device, Dyson engineers tested the adaptability of Dyson Zone air purification headphones with different head shapes, which also provides a reference for the clamping force of the headphone headband, the geometry and material of the mask, and the adjustability of the device.
In addition, dyson zone air purification headphones are also products jointly created by Dyson's global technical team, jointly developed and designed by a team of engineers from the United Kingdom, Singapore, Malaysia and China, with engineers from Southeast Asia responsible for the development of software to ensure a smooth user experience and provide intelligent, tangible air and noise pollution query functions.
Dyson has been developed with durability in mind, and like all Dyson machines, Dyson Zone air purification headphones have undergone temperature testing, drop testing, wear testing of materials and fabrics, button firmness testing, and more. In addition to testing in the UK, inspection engineers at Dyson Malaysia R&D Centre also conducted various tests on the products in Malaysia, where the temperature and humidity are higher than in the UK.
Dyson Zone air purification headphones are expected to go on sale in autumn 2022 in Dyson's online and offline direct stores, as well as on dyson's official website. Specific time-to-market varies slightly from country to country, and full product specifications and listing details will be announced in the coming months.
