Patent number: 11468750Abstract: 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.Type: GrantFiled: October 13, 2020Date of Patent: October 11, 2022Assignee: Lofelt GmbHInventors: Maximilian Weber, James Mazur, Gwydion ap Dafydd, Daniel Büttner

Patent number: 11192141Abstract: A vibrating actuator is disclosed, comprising: a magnet arrangement including at least one magnet (1); a hollow member (4) comprising at least one coil member (2) with a coil transversally surrounding a cavity (5) forming a longitudinal passageway for receiving the magnet arrangement and permitting a longitudinal relative movement between the hollow member (4) and the magnet arrangement; and elastic means (6) interconnecting the magnet arrangement and the hollow member (4). In one aspect, the elastic means (6) are thin membranes having an oblong shape with transversal indentations (10) on their opposite long sides. In another aspect, at least two magnets (1) are arranged with same polarities facing each other inside a magnet frame (8) at least partially surrounding the magnets (1). Furthermore, methods for assembling the magnet arrangement of a vibrating actuator, the hollow member of a vibrating actuator, and the overall vibrating actuator are disclosed.Type: GrantFiled: March 23, 2017Date of Patent: December 7, 2021Assignee: Lofelt GmbHInventors: Amir Berrezag, Daniel Büttner

Patent number: 11120673Abstract: 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.Type: GrantFiled: June 7, 2019Date of Patent: September 14, 2021Assignee: Lofelt GmbHInventors: Daniel Büttner, Sebastian Roos

Patent number: 11070119Abstract: A vibrating actuator is disclosed, comprising: a magnetic part including at least two magnets arranged with same polarities facing each other; a receiving part including a hollow member with a cavity for receiving the magnetic part and at least one coil wrapped around the hollow member and fixed thereto; elastic elements interconnecting the magnetic part and the hollow member; and a chassis. In one aspect, the magnetic part is fixed to the chassis via attachment elements such that the magnetic part, attachment elements and chassis are stationary, and the receiving part performs a linear movement with changing direction causing the vibration when an alternating current passes through the coil(s). In another aspect, the elastic elements are flat elastic metal or plastic membranes. In another aspect, a magnetic guidance member of ferromagnetic material partly surrounding the hollow member and coil(s) is mounted to the longitudinally outer ends of the magnetic part.Type: GrantFiled: February 8, 2019Date of Patent: July 20, 2021Assignee: Lofelt GmbHInventors: Amir Berrezag, Daniel Büttner
