According to a list recently announced by the United States Trademark and Patent Office (USPTO), Apple has obtained a patent for a cylindrical microelectromechanical system (MEMS) audio component, which can be used in iPad, iPhone, In MacBook, AirPods and other products.
While digital products are shrinking in size, users are increasingly demanding high-quality audio. A higher-quality audio experience often requires larger speaker components. How to reconcile the two has become a challenge for manufacturers such as Apple.
Apple explored a cylindrical corrugated MEMS structure in the patent, using an open cylindrical core that can be fluidly coupled to the MEMS speaker and installed between the front volume and back volume of the speaker.
Under the action of an applied voltage, the cylindrical MEMS structure can deform, causing the position between the upper and lower fixed edges to bend. These fixed edges are hermetically fixed on the upper and lower substrates to generate sound while preventing the air around the upper and lower fixed edges from escaping. vent.
The relevant design sketches in the patent as follows:
