Claim 12:
13. The thermal detection system of claim 8, wherein the area indicating unit comprises one of a sound generator and a collapsible boundary structure;
wherein the sound generator is configured to, when the thermal detection result indicates that a temperature at a boundary of the detection area reaches a first threshold value, or indicates that a rate of change of the temperature at the boundary of the detection area reaches a second threshold value within a predetermined period of time, generate a sound signal to indicate that the electronic device is passing through a boundary of an audible area of the human-perceptible area;
wherein the collapsible boundary structure is arranged to indicate a boundary of the visible area of the human-perceptible area; when the thermal detector is activated, the collapsible boundary structure is stretched out to be located on a boundary of the detection area.
