A vibrotactile transducer provides a point-like vibrational stimulus to the body of a user in response to an electrical input. The apparatus includes a housing held in contact with the skin and a moving mechanical contactor protruding through in an opening in said housing and preloaded into skin. The contactor is attached to a torroidal moving magnet assembly suspended by springs in a magnetic circuit assembly consisting of a housing containing a pair of electrical coils. The mass of the magnet/contactor assembly and the compliance of the spring are chosen so that the electromechanical resonance of the motional masses, when loaded by a typical skin site on the human body, are in a frequency band where the human body is most sensitive to vibrational stimuli. By varying the drive signal to the vibrotactile transducer and activating one or more transducer at specific location on the body using an appropriate choice of signal characteristics and/or modulation, different information can be provided to a user in a intuitive, body referenced manner.

A device, system, and method of assistance for visually impaired users. The system comprises a plurality of video cameras, often head mounted, computer processors and associated support devices and algorithms configured for computer vision, and a user worn haptic band comprising a plurality (two or more) of distantly spaced haptic transducers. This haptic band is worn such that user's hands are free for other tasks. The system uses its video camera, depth processing algorithms, and object recognition algorithms (hardware and/or software based) to identify a limited number of navigationally important objects. The spatial locations of each object deemed important is output to the user by varying output to the haptic transducers accordingly. The system is configured to identify and report objects as generic objects, identified objects, and potential obstacle objects. The system can also optionally provide audio information pertaining to these objects as well.

Each tactile transducer is designed to wear by musician and contained in a wearable housing, the housing does not include electric source for supplying electricity to the transducer. The signal generator controlled by conductor, bandleader, lead musician or music instructor can output electric signal on a plurality of independent communication channels corresponding to a plurality of independent timing scheme, and also be suitable for generating output with presetting time-shift between the signals.

A tactile rhythm generator for use by an athlete in training generally includes a signal generator for producing an electrical signal according to a desired timing scheme and a tactile transducer in electrical communication with the signal generator. The tactile transducer, which may take the form of a piezoelectric device, a buzzer, electrodes or any substantial equivalent, is adapted to impart a tactile sensation to the athlete in response to the generated electrical signal. A strap, which may be formed from an elastic material or a soft cloth material with hook and loop fasteners, is provided to secure the tactile transducer in place on the musician's body.

An improved method of treating depression in a person can be generally said to include applying to a body area of the person a therapeutic stimulation device having a tactile transducer that is positioned proximate the body area, and emitting with the tactile transducer a vibrational output toward the body area. A therapeutic stimulation device and a non-transitory machine-readable storage medium are also disclosed.

One embodiment of the present disclosure sets forth a technique for determining the location of an object with a haptic transducer device.

Presenting audio signals to a user is comprised of receiving audio signals to be presented, separating the audio signals into plural discrete frequency components extending from a low frequency to a high frequency, translating each of the frequency components into control signals, and applying the control signals to an array of tactile transducers for sensing by the user.

A method of manufacturing a tactile transducer includes providing a substrate; performing a surface treatment on the substrate by using an electrolysis system; depositing a buffer layer on the substrate; forming a layer of a piezoactive thin film on the substrate; baking the piezoactive thin film; annealing the piezoactive thin film; performing a poling process on the piezoactive thin film; and depositing a top electrode on the piezoactive thin film.

A Therapeutic High Backed Reclining Gaming Chair with Surround Sound and a Tactile Transducer. The chair is designed using Human Factors Engineering. Design characteristics are specifically fashioned to afford therapeutic support and comfort based on the typical movements of seated gaming participants. It is a recliner with targeted padded support, fixed armrests, adjustable headrest, footrest and a repository for gaming remotes and controllers. 5.1 Surround Sound is provided via a plurality of speakers recessed within the chair core and strategically directed toward the occupant. The chair core contains sound deadening materials. There is minimal sound bleeding. Vibrational energy is transmitted including controlling sound and vibrations, which are transmitted through speakers and the transducer.

The instant invention is directed to a tuned inductive coil that is designed to work within the field of a separate NFC (Near Field Communication) tag for the purpose of harvesting ambient energy that is transmitted during the bi-directional signal process in order to effect unique functionality which requires higher energy consumption and which would not otherwise be possible or as effective absent such harvest of energy such as, but not limited to operation of a light, a sound or a tactile transducer or similar circuitry, separate of the function of the nearby NFC tag.

A device (10) used by a drummer to produce low frequency signals in response to the playing of a bass drum (D). Low frequency signals from the device are first amplified and then sent to a subwoofer near the drummer, or tactile transducer connected to the drummer's chair (C). This results in a powerful shaking effect each time the drum is struck. The device is used in a stand alone audio circuit and does not require connection into a band's complete audio system. This is important because it allows the drummer to feel a powerful shaking effect each time the drum is struck when practicing or while playing in situations where an audio system is limited or non-existent.

Embodiments described herein relate to methods and apparatus for outputting a haptic signal to a haptic transducer. A method for triggering a haptic signal being output to a haptic transducer comprises receiving an audio signal for output through an audio output transducer; determining whether the audio signal comprises a haptic trigger based on an indication of a rate of change of an amplitude ofthe audio signal, and responsive to determining that the audio signal comprises a haptic trigger, triggering the haptic signal to be output to the haptic transducer.
