The vibrating actuator has a second moving part 210 having one or more coils 410. The one or more coils 410 are wound over the arrangement of the magnets 320 such that the first moving part 210 can freely slide into the second moving part 220.

Abstract: Methods and systems of authoring audio signal(s) into haptic data file(s) are disclosed. An audio analysis module analyses the audio signal(s) using filterbank(s) or by performing a spectrogram analysis. Transients are detected in the audio signal. If present, the transients are processed to determine a transient score and a transient binary. A database stores device specific information and actuator specific information. A haptic perceptual bandwidth of an electronic computing device having an embedded actuator is determined by using information from the database. A user interface allows modification of time-amplitude values and transient values based on the determined haptic perceptual bandwidth. Authored time amplitude values are aggregated in authored audio descriptor data, which is passed to a transformation module that fits the data into the haptic perceptual bandwidth and implements algorithms to produce transformed audio descriptor data.

Abstract: A computer implemented method and system of transforming an audio signal into a haptic data to fit into a haptic perceptual bandwidth of an electronic device having at least one actuator is disclosed. The method and system receives the audio signal; filters the audio signal into one or more frequency bands with each frequency band having a center frequency and time-amplitude values; authors the one or more frequency bands by modifying the time-amplitude values by changing, appending or deleting one or more time amplitude values to create an authored audio descriptor data; calculates an available bandwidth and the haptic perceptual bandwidth of the electronic device having at least one embedded actuator and fits the authored audio descriptor data into the haptic perceptual bandwidth of the electronic device to create a haptic data file.

Abstract: Systems and methods for generating a haptic output from an audio signal having a continuous stream of sampled digital audio data are provided. A haptic processing system receives the digital audio data, analyses the digital audio data for processing and extracts haptic signals for generating a haptic effect through an actuator. The method includes passing the digital audio signal on through dynamic processor(s), adjusting the dynamic range of the digital audio signal, extracting the signal envelope of the audio data, synthesising low-frequency signals from the extracted signal envelope, and enhancing the low-frequency content using a resonator. The haptic output is generated by mixing the digital audio signal with outputs from the different modules of the haptic processing system. An analytics module monitors, controls and adjusts the processing of the digital audio signal at the noise gate module, the compressor module and the envelope module to enhance the haptic output.

Abstract: The present invention pertains to the field of control and manipulation of a digital audio signal by a user manipulable touch sensitive control surface. The present invention is specifically applicable to user manipulation of digital audio signals by disc jockeys (DJs). A touch sensitive surface substantially circumferential in shape is divided into two regions: an inner or central portion and an outer or circumferential portion. The inner portion responds to linear motion imparted by the user while the outer portion responds to circumferential motion. The linear motion imparted by the user in the central portion is used manipulate a digital audio data stream in order to impart a scratch effect.
