摘要： An audio-haptic signal generator for a haptic system including an amplifier coupled to a haptic actuator is described. The audio-haptic signal generator includes an audio input configured to receive an audio signal; a haptic input configured to receive a haptic signal and a controller configured to receive to at least one of the haptic signal, an amplifier state and a haptic actuator state. A mixer is coupled to the audio input and the haptic input. The mixer has an output configured to be coupled to a haptic actuator. The controller controls the mixer to process the audio signal dependent on at least one of a characteristic of the haptic signal, an amplifier state, and a haptic actuator state. The mixer is configured to mix the haptic signal and processed audio signal on to output the mixed haptic signal and processed audio signal.

摘要： A peak current limiter for an audio system comprising at least two audio amplifiers is described. The peak current limiter comprises at least two audio inputs; at least two audio outputs, each audio output being coupled to a respective one of the at least two audio inputs and configured to be coupled to a respective one of the at least two audio amplifiers. The peak current limiter is configured to receive an audio signal on each of the respective audio inputs. The peak current limiter determines a current value required by each of at least two audio amplifiers. An audio characteristic of at least one of the received audio signals is modified to limit the total current supplied to the at least two amplifiers below a predefined maximum current value.
