Last Tuesday there was more than one Apple patent that the company had been awarded. What were these patents for? Read on to know more about these latest patents.
Apple Patent Case Victory
Two Apple patents were granted on Tuesday for the maximisation of space in portable devices. One patent is for an acoustic panel system with very high-quality sound in small enclosed spaces. The other one is for a woven display for the Apple Watch.
The first patent awarded by the U.S. Patent and Trademark Office with Apple’s U.S. Patent No. 9,525,943, is a “Mechanically actuated panel acoustic system.” This is for an audio system that is designed in such a way that through direct vibrations in its sub-panels housed in a flat space, it creates high-quality sound.
Simply put, traditional and dynamic speaker systems have large diaphragms. These are usually conical in shape and have a voice coil wire attached. The voice coil is housed in a frame right next to a large and permanent magnet. When electrical current passes through the voice coil, a magnetic field is created that reacts with the magnet and pushes & pulls the diaphragm that it is attached with. This pushing and pulling when interpreted by the conversion components of the audio signal on board, creates pressure waves in the air in the diaphragm. This creates the sound.
Other Apple products have micro speakers that function in more or less the same way, even if on a much smaller scale. The whole design of the voice coil integrally attached to the diaphragm’s panel structure and the permanent magnet translate into a self-sustaining unit. Even so, Apple has been looking to maximise volume with as little distortion as possible and increasingly large back volumes.
The patent for a “Woven display” is a process of interweaving light-transmissive material and traditional textiles. There are light pipe fibres that, when connected to LEDs or other light sources, can create computer generated imagery. This is mostly used in secondary displays on devices that are worn like Apple Watch. This involves laying down light transmissive fibres like glass, nylon, and polymers next to opaque fibres to create a pattern.
Both these patents were applied for in 2014 and were finally granted in 2016.
