For the AirPods wireless Bluetooth headphones launched last year, Apple may add an automatic noise cancellation function through a newly applied patent, which can also effectively eliminate ear pressure problems caused by sound waves, air pressure and other factors when wearing headphones and listening.
According toAppleinsider websiteThe report pointed out that the patent application filed by Apple in January 2016 was approved by the US Patent and Trademark Office earlier, and may be used in the new AirPods product.
This feature, called the In-ear Speaker Hybrid Audio Transparency System, is similar to a technology previously used by Bose in its headphone products. It automatically identifies the user's wearing position and sound content, automatically opening or closing valves within the headphones to adjust the headphone sound pattern according to the digital sound output mode as the user listens to music. For example, closing all valves within the headphones creates an in-ear listening experience, while opening them to increase external sound.
Compared to traditional noise-canceling headphones that achieve sound cancellation effects through structural designs that isolate external sounds or by actively emitting active reverse sound waves, Apple's design this time is more similar to the former, but it also has an automatic internal valve adjustment function, so that the listening process can automatically adjust the sound output mode according to the content of the music being played, thereby avoiding rapid power loss of the device due to increasing the volume or emitting reverse sound waves to eliminate external sounds. It can even reduce ear pressure problems caused by factors such as sound waves and air pressure according to different wearing modes.
It is still unclear whether Apple will announce the launch of new AirPods wireless Bluetooth headphones this year, nor is it certain whether the content of the approved patent will be used in the new headphone products.
