Audio-haptic signal generator

An audio-haptic signal generator for a haptic system, the haptic system comprising an amplifier coupled to a haptic actuator, the audio-haptic signal generator comprising:

• an audio input configured to receive an audio signal;
• a haptic input configured to receive a haptic signal;
• a controller configured to receive at least one of the haptic input signal, an amplifier state and a haptic actuator state;
• a mixer coupled to the audio input and the haptic input and having a mixer output configured to be coupled to the amplifier;
• wherein
• the controller is further configured to control the mixer to process the audio signal dependent on at least one of a characteristic of the haptic signal, the amplifier state, and the haptic actuator state;
• and
• wherein the mixer is configured to mix the haptic signal and the processed audio signal and to output a mixed audio-haptic signal;
• wherein the mixer comprises an audio processor coupled to an adder and wherein the audio processor input is coupled to the audio input, the audio processor output is coupled to a first input of the adder and the haptic signal input is coupled to a second input of the adder.
