ELECTRONIC DEVICE WITH MAGNETIC FIELD SENSOR DESIGN FOR DETECTION OF MULTIPLE ACCESSORIES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18231725 titled 'ELECTRONIC DEVICE WITH MAGNETIC FIELD SENSOR DESIGN FOR DETECTION OF MULTIPLE ACCESSORIES
Simplified Explanation
- The patent application describes an electronic device that has a device magnet designed to connect with an accessory device magnet. - The device also includes a display assembly and a magnetic field sensor that can detect the presence of the accessory device magnet, indicating that the accessory device is covering the display assembly. - To prevent interference, the device has a shunt assembly that reduces the strength of the device magnet's magnetic field as detected by the magnetic field sensor, while still allowing the magnetic field from the accessory device to reach the sensor. - This setup allows the magnetic field sensor to be placed near the device magnet without being triggered by it. - Additionally, the electronic device may have a microphone, and communication between the microphone and an integrated circuit can be stopped if the magnetic field sensor detects the presence of the accessory device magnet.
Original Abstract Submitted
An electronic device is disclosed. The electronic device includes a device magnet designed to magnetically couple with an accessory device magnet. The electronic device further includes a display assembly and a magnetic field sensor configured to detect the accessory device magnet, thereby providing an indication that the accessory device is covering the display assembly. The electronic device further includes a shunt assembly designed to reduce the magnitude of the magnetic field of the device magnet, as determined by the magnetic field sensor, while allowing the magnetic field from the accessory device to sufficiently reach the magnetic field sensor. As such, the magnetic field sensor can be placed near the device magnet without triggering the magnetic field sensor. The electronic device may further include a microphone. Communication between the microphone and an integrated circuit can cease based on the magnetic field sensor detecting the accessory device magnet.
