System method for accessory adapter with power supplying capabilities wherein power conductive element is either active or passive depending on placement of electrical contacts

摘要

An electronic device and an accessory are provided. The electronic device is installed on the accessory and identifies a type of the accessory. The electronic device includes a housing, a processor and an active sensing element. The processor and the active sensing element are disposed in the housing, and the active sensing element is electrically connected to the processor. The accessory includes a body and a passive sensing element, and the passive sensing element is disposed in the body. When the electronic device is installed on the accessory, the processor identifies the type of the accessory through that the active sensing element detects the passive sensing element, and the processor starts an operating mode relative to the accessory according to the type of the accessory. A method of operating an electronic device and an accessory is also provided.
