AUDIO AND HAPTIC SIGNAL PROCESSING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240045505 titled 'AUDIO AND HAPTIC SIGNAL PROCESSING

Simplified Explanation

The abstract describes a patent application for audio and haptic signal processing systems and methods. The method involves generating a haptic drive signal based on an input audio signal for driving an audio speaker. Data components indicative of the behavior of the audio speaker when driven by the input audio signal are derived from the audio signal. Each data component is associated with a specific frequency range. A haptic drive component is determined from each data component, and a gain is selected for each respective frequency range. The selected gain is applied to the respective haptic drive component to produce gain-adjusted haptic drive components. A haptic drive signal is determined from the gain-adjusted haptic drive components, which produces a mechanical behavior of the haptic actuator when used to drive it.

• Accessibility for individuals with hearing impairments through tactile feedback.

Original Abstract Submitted

audio and haptic signal processing systems and methods are provided. there is provided a method for haptic drive signal generation. the method comprises receiving an input audio signal for driving an audio speaker. the method further comprises deriving, from the audio signal, data components indicative of behaviour of the audio speaker when being driven by the input audio signal, each data component being associated with a respective frequency range. the method further comprises determining a haptic drive component from each data component. a gain is selected to provide to each of the haptic drive components, the gain being selected for each respective frequency range. each selected gain is applied to the respective haptic drive component to produce gain adjusted haptic drive components. a haptic drive signal is determined from the gain adjusted haptic drive components, the haptic drive signal being so as to produce a mechanical behaviour of the haptic actuator when the haptic drive signal is used to drive the haptic actuator
