AI Technical Summary
Technical Problem
In combo devices, the speaker and motor fail to function as expected, resulting in frequency response amplitude and phase distortion, which affects performance and user experience.
Method used
A signal fusion unit is used to fuse the digital signals of the loudspeaker and the motor. A power amplifier performs analog-to-digital conversion and power amplification, an analog crossover performs frequency division, and a signal processor predicts voltage data for correction to ensure that the analog signals of the loudspeaker and the analog signals of the motor are consistent with the digital signals.
Benefits of technology
This effectively ensures that the speaker and motor work as expected, improving the performance of the Combo device and the user experience.
