| Abstract: | Based on the wheatstone bridge principle ,the time variant characteristic of headphones has been studied.The results from a series of experiments indicate: the temperature on the headphone increases with the rise of the input stimuli of the headphone, resulting in a variance in the resistance of the voice coil of the headphone; this change consequently destroys the headphone response, even leads to a malady in the headphone. |

| Keywords: | dynamic headphone voice coil thermal influences |
