摘要： A control device and an associated method for driving a multi-function speaker supporting a plurality of predetermined functions including at least an audio function and a non-audio function includes a digital signal mixing block and a digital-to-analog block. The digital signal mixing block is arranged for receiving a plurality of digital input signals corresponding to the predetermined functions, respectively, and generating a digital mixed signal according to the digital input signals. The digital-to-analog block is coupled to the digital signal mixing block, for generating an analog driving signal to the multi-function speaker according to the digital mixed signal.

摘要： An amplifier processes a differential input received at a differential input port. The amplifier includes a first amplifier circuit and a second amplifier circuit. The first amplifier circuit is disposed in a first signal path between a first input node and a first output node of the amplifier, and arranged to amplify a first input signal received at the first input node and accordingly generate a first amplified signal to the first output node. The second amplifier circuit is disposed in a second signal path between a second input node and a second output node of the amplifier, and arranged to amplify a second input signal received at the second input node and accordingly generate a second amplified signal to the second output node. A driving capability of the first amplifier circuit is different from a driving capability of the second amplifier circuit.
