Introduction

Tsung-Nan Wu is a prominent inventor based in Zhubei, Taiwan. He has made significant contributions to the field of electronic devices, holding a total of 8 patents. His work focuses on enhancing the functionality and efficiency of electronic systems.

Latest Patents

One of his latest patents is an electronic device and control method for managing a Linear Resonant Actuator (LRA). This device includes a signal generator, a driver, a delay unit, a sensor, and a Digital Signal Processor (DSP). The signal generator produces a digital signal, which the driver uses to operate the LRA. The delay unit ensures that the digital signal is delayed for a specific time to create an estimated voltage signal. The sensor monitors the current flowing through the LRA, generating a sensing current signal. The DSP then adjusts the resonant frequency or gain value of the signal generator based on the estimated voltage and sensing current signals.

Another notable patent is for an electronic device that controls multiple speakers using a single functional chip. This device comprises two speakers, a functional chip, a parameter extraction circuit, an audio processing module, a gain adjusting circuit, and a current detecting unit. The current detecting unit, located within the functional chip, measures the driving current of the two speakers. The functional chip provides the necessary driving voltage based on an output signal and converts the analog currents and voltages of the speakers into digital formats. The parameter extraction circuit gathers data on each speaker's parameters, while the audio processing module determines the final gain for each physical quantity. The gain adjusting circuit then outputs the signal by modifying the gain of the input signal according to the final gain values.
