Abstract: The present invention relates to a temperature measuring device of a speaker voice coil and, more specifically, to a temperature measuring device capable of not only reducing working time but also improving the accuracy of a measured value when measuring the heating temperature of the voice coil. To achieve the forementioned purposes, the present invention includes: a voltage generator which provides a predetermined DC voltage to be applied in the voice coil; a D/A converter which applies the DC voltage which is provided from the voltage generator in the voice coil by converting the DC voltage into a reference voltage of a predetermined magnitude; a signal generator which outputs a signal for driving the voice coil; an amplifier which drives the voice coil by amplifying the signal of the signal generator; a filter which blocks an AC voltage and passes only a DC voltage in a voltage which is generated by driving the voice coil; an A/D converter which converts the DC voltage which passes through the filter into a digital signal; and a micro-processor which controls the D/A converter and converts a DC voltage which is measured by the A/D converter into the heating temperature of the voice coil by comparing the DC voltage with the reference voltage. The present invention is able to not only reduce working time but also improve the accuracy of a measured value when measuring the temperature of a voice coil because the heating temperature of the voice coil can be automatically measured by an easy setting of a user.
