CTOnews.com, May 25 / PRNewswire-FirstCall-Asianet /-- Apple announced a new patent application today hinting that the company may launch the "find my Apple Pencil" function in the future, which uses sound waves to locate lost Apple Pencil. Interestingly, the method described by Apple does not use ultra-wideband chips, but uses acoustic signals.

Currently, users can use the Find My app to track most Apple devices, but not the Apple Pencil, which may change in the future. The U.S. Patent and Trademark Office today announced a patent application from Apple to add an Apple Pencil or other peripheral input device to the list of "find my" device services.

According to the patent, the missing Apple Pencil or other peripheral input devices can be located by an acoustic resonator integrated in the pen case structure, which can be placed at the opposite end of the pen tip and can be part of the shell, which is thinned to an engineering thickness with a specific resonance behavior or frequency.

In some of the examples given by Apple, electronic devices can send location requests to the pen and allow the pen to generate acoustic signals for a specified target detector through an acoustic resonator.

Resonance frequency refers to the frequency at which an object vibrates at the maximum amplitude. The user may have experienced this phenomenon on an airplane or train. When an object on the tray suddenly begins to vibrate crazily, this is because the frequency generated by the vehicle matches the resonance frequency of the object. The patent describes the use of a user's iPhone to generate an acoustic signal that matches the resonant frequency of the Apple Pencil end cover to make it vibrate. Although this is a relatively rough positioning method, it has some advantages, which is that it is cheap and takes up little space.

CTOnews.com notes that this method does not help users find Apple Pencil forgotten in the distance because it needs to be within the range of sound waves, but at least it can help users find the Apple Pencil around them.
