American audio equipment manufacturer Bose is pondering the concept of wireless earbuds capable of cooling themselves, as indicated by a new patent awarded to the company by the United States Patent and Trademark Office earlier this week. Officially published on Thursday, the patent and its designs seen in the gallery below describe a pair of headphones coming in the form of a fitness-oriented offering made of elastomer, i.e. rubber, filled with materials capable of changing their state of aggregation from solid to liquid and vice versa. The idea is that the solid matter inside the earbuds would turn into liquid once the user's body reaches a certain temperature and the device itself starts heating up so as to stop the change or at least slow down the temperature increase until the earlobe cools down.
The materials themselves would be able to change their state of aggregation at specified temperatures, the patent reveals, meaning Bose could deliver a lineup of headphones that have different definitions of overheating and strive to keep themselves below a user-specified temperature level. Both the body and the tip of every earbud would be filled with such shape-shifting matter that would likely come in gel form. Bose appears to have already created a dummy unit of the contraption for the purposes of filing its latest patent with the USPTO, with the creation itself being originally submitted for review in mid-October of 2016. It's presently unclear whether the Framingham, Massachusetts-based firm is still pursuing such solutions with the goal of commercializing them.
The patent was initially filed before Bose entered the truly wireless earbud segment, with the company recently also experimenting with other emerging technologies such as artificial intelligence. The manufacturer's QuietComfort 35 II headphones launched last September hence support the Google Assistant, with the firm already hinting at a continued pursuit of such solutions in the future.
