Abstract
A single power amplifier-driven signal control system for driving a two-in-one device integrating a first component capable of generating sound and a second component capable of generating vibration, where the two-in-one device includes a first input end and a second input end for introducing a signal respectively to the first component and the second component. The signal control system includes a signal control module, configured to determine an operating mode required for a current state based on an input signal, and generate an output signal for driving the two-in-one device based on the input signal and operating mode; a power amplifier, configured to amplify the output signal to obtain an amplified drive signal; and a front-end circuit module, configured to load the amplified drive signal to the first input end and/or the second input end to drive the first component and/or the second component to operate.
