Described herein are wearable sensory stimulation and monitoring devices that can be worn around the back of the neck along and in contact with the spine.

Apparatuses described herein stimulate one or more senses including auditory, tactile or olfactory. Apparatuses are also described that allow for sensing and monitoring of physiologic parameters such as heart rate, blood pressure and movement. The device also has features that allow for easy attachment or integration to articles worn on the head such as augmented reality and virtual reality accessories to provide visual stimulation and entertainment.

Equipment including a casing wherein are located: a box; a first loudspeaker disposed inside the box, the first loudspeaker being arranged to broadcast sounds outwards from the casing; a main electronic board placed in the casing outside of the box and on which is mounted, at least one power supply module producing a first power supply voltage; a connecting device passing through the wall of the box; a secondary electronic board inside the box on which is mounted, at least one first amplifier connected to the first loudspeaker, the secondary electronic board being connected to the main electronic board via the connecting device to power the first amplifier with the first voltage.

A sound reflection assembly comprises a rigid structure having a sound reflection section and a support section, a rigid part in the support section, etc. A directional sound generation module is placed on the rigid part. The directional sound generation module is spatially oriented to direct sound waves generated by one or more speaker elements in the directional sound generation module towards the sound reflection section to be reflected by the sound reflection section towards an audience in an audience area in front of the sound reflection assembly. The directional sound generation module may be a sound bar.

Systems, methods, and devices are provided for a sub-frequency volume control unit for providing additional control of sub-frequency volume in a signal provided from a source unit to a subwoofer, without exceeding a maximum volume level of the subwoofer, the source unit having a master volume controller and a maximum volume level. The sub-frequency volume control unit may comprise: a sub-frequency volume control circuit for receiving the first audio signal and for generating a sub-amplifier signal; a variable volume control input device, wherein the sub-amplifier signal is amplified by an amount that is variably selected manually using the variable volume control input device, and wherein the sub-frequency volume control circuit is configured to amplify the first audio signal if, and only if, the master volume controller is providing the first audio signal at less than the maximum volume level; and an output for providing the sub-amplifier signal to a subwoofer.

Systems and methods for providing augmented arrays for audio playback are disclosed. An example playback device includes a first transducer configured to output audio along a first acoustic axis and a second transducer configured to output audio along a second acoustic axis. The playback device is configured to receive a source stream of audio content including at least a first input channel and a second input channel. The device plays back first audio output via the first transducer based on the first input channel and directed along the first acoustic axis, and plays back second audio output via the second transducer based on the second input channel and directed along the second acoustic axis, wherein the second audio output at least partially cancels the first audio output along a first spatial region offset from the first acoustic axis.

Embodiments include a system for enhancing an audio listening experience, the system comprising an electrical device configured to impart vibrations, to a chest area of a user, based on an incoming audio signal and detect an acoustic resonance generated in a chest cavity of the user as a result of the vibrations; and an acoustic system configured to output the incoming audio signal in synchrony with the vibrations imparted to the chest cavity and simultaneously deliver haptic and audible vibrations associated with the acoustic resonance to the ears of the user. Embodiments also include a headphone system comprising an audio driver for outputting an incoming audio signal to the ears; and at least one acoustical port configured to deliver haptic and audible vibrations to the ear, the haptic and audible vibrations being associated with an acoustic resonance generated in a chest cavity of the user based on the audio signal.

A speaker assembly is provided with a housing, a first speaker and a second speaker both supported by the housing, and a controller. The controller is programmed to determine a location of the housing relative to a docking station. The controller is further programmed to disable the second speaker and control the first speaker to play a low-frequency component of an audio signal in response to the housing being located proximate to the docking station.

A set-top box, integrating a speaker having an acoustic box. At least two first loudspeakers and one second loudspeaker are integrated. The two first loudspeakers are positioned at the front and on each side of the acoustic box. A central axis (X2) of a membrane of the second loudspeaker is a vertical axis. The set-top box includes, in addition, a main electronic board having a decoding module and an audio module. The second loudspeaker and the main electronic board are positioned on either side and extending successively along a length (L) of the set-top box which is perpendicular to a front-to-rear axis of the acoustic box.

Disclosed are an apparatus and method of processing an audio signal to optimize audio for a room environment. One example method of operation may include recording the audio signal generated within a particular room environment and processing the audio signal to create an original frequency response based on the audio signal. The method may also include identifying a target sub-region of the frequency response which has a predetermined area percentage of a total area under a curve generated by the frequency response, determining whether the target sub-region is a narrow energy region, creating a filter to adjust the frequency response, and applying the filter to the audio signal.

A sound apparatus includes a first vibration member, a second vibration member adjacent to the first vibration member, a third vibration member adjacent to the second vibration member, a first vibration apparatus configured to vibrate the first vibration member and the second vibration member and output a sound of a first pitched sound band and a sound of a second pitched sound band which differ, and a second vibration apparatus disposed at a rear surface of the third vibration member and configured to vibrate the third vibration member and output a sound of a third pitched sound band which differs from the sound of the first pitched sound band.
