description A temperature detecting and controlling integration device applied for the micro speaker is provdied, which includes a current and voltage filters, an adder, a power amplifier, an extraction resistor, a current integrator and voltage integrator, an arithmetic unit, and a non-linear temperature controlling unit. After the filter receives an input signal, the power amplifier adjusts the power amplification, and the multi-frequency detection signal is generated with the waveform generator. The extracted signal is generated to drive the micro speaker to emit a sound signal. Afterwards, the voltage signals are extracted at two ends of the coil and the temperature signal is obtained by converting, capturing, and integrating to pass the temperature value to the external device, and the temperature value of the non-linear temperature-controlling unit is analyzed to adjust the compensation gain in real time. Then, the smoothly control of speaker temperature and stable playbakc of the sound signals is played can be achieved.
