【 摘 要 】
The voice coil temperature coefficient is a crucial parameter in the field of voice coil temperature measurement technology, speaker thermal effect, and others. A measurement method for wire resistance temperature coefficient based on heat transfer model is presented in this paper. Measure the voltage at both ends of the coil and the current through the coil before and after the temperature rise by simply energizing the coil in the heat resistance box under the condition of stable ambient temperature. The temperature coefficient of the coil can be obtained according to Ohm's law and heat transfer model in the method.
