APPARATUS, SYSTEMS AND METHODS FOR DETECTING INSERTION OR REMOVAL OF AN AUDIO ACCESSORY FROM AN ELECTRONIC DEVICE

摘要

According to one aspect, an electronic device for detecting an audio accessory. The electronic device includes an audio jack having at least two detection terminals. The detection terminals are spaced apart and positioned within a socket of the audio jack so when an audio plug of the accessory is inserted into the socket of the audio jack, the detection terminals will be shorted. The presence of a short between the detection terminals is indicative that the audio accessory is present.
