Latest Patents
One of Liu's latest patents is a temperature detecting and controlling integration device specifically designed for micro speakers. This device operates by receiving an input signal through a filter, which allows a power amplifier to adjust power amplification. A multi-frequency detection signal is then generated using a waveform generator. The extracted signal drives the micro speaker to emit sound. Voltage signals are captured at both ends of the coil, and the temperature signal is obtained through conversion, capturing, and integration. This process enables the temperature value to be communicated to an external device. Furthermore, the temperature value of the non-linear temperature-controlling unit is analyzed to adjust the compensation gain in real time. This innovation ensures smooth control of speaker temperature and stable playback of sound signals.
