Definitions

  • the present invention refers to a sound chair and sound transmitting modules.
  • the sound transmitting modules are designed to enable the physical sensation of sound and vibrations (e.g. music, sound therapy sounds, brainwave entrainment sounds) by a user by means of a distributed structure-borne sound transmission via the skin, the bones or other parts of the user's body.
  • Sound is typically perceived by the ears of a listener through sound vibrations transmitted by air.
  • body-borne sound i.e. structure-borne sound within a (human) body.
  • Such devices for the excitation of body-borne sound are designed as chairs and a number of such sound chairs are commercially available. There have been a number of patent applications for sound chairs filed.
  • US 4,055,170 A discloses a health promoting apparatus comprising a chair, bed or the like with a loudspeaker incorporated therein. An opening formed in the chair is closed by a pretensioned flexible sheet. The sound waves from the loudspeaker cause the flexible sheet to vibrate, said vibrations being transmitted to a chair occupant.
  • US 8,638,966 B2 discloses a sound enhancing system including a haptic chair formed of a chair and plural speakers mounted to the chair.
  • the speakers receive audio input from a subject audio source and generate corresponding sound vibrations.
  • the chair is configured to deliver the generated sound vibrations to various body parts of a user seated in the chair through the sense of touch and by bone conduction of sound.
  • a visual display viewable by the user corresponds to the generated sound vibrations and is indicative of the corresponding audio input.
  • the sound enhancing system enhances user experience of the audio input visually, by the sense of touch, or by bone conduction of sound or any combination thereof.
  • US 2011/0251535 A1 discloses an apparatus and method for introducing multisensory integration.
  • the apparatus includes an ergonomically contoured seating device, at least one vibrating acoustic device, at least one plate for dispersing vibration throughout the entire seating device, a rotatable mechanism for rotating the seating device.
  • US 5,101,810 A discloses an apparatus for therapeutic application of vibro-acoustic energy to a human body, including a closed box with at least one sound opening in which is arranged a loudspeaker directed towards a part of the body. Upholstery is disposed between the box and the body at the location of the loudspeaker and has air passages. Low frequency signals are supplied to the loudspeaker and to one or a plurality of external loudspeakers. Music is supplied to the external loudspeakers. The low frequency signals are influenced either in step with the music, in a predetermined relation to the music, or in predetermined rhythm. As storage medium for sound there may be used a tape cassette or compact disc in which at least one of the sound channels contains the influenced low frequency signal in the frequency range 30-120 Hz and the remaining sound channels contain pure music.
  • All these sound chairs use a regular chair or other kinds of bases that lead to enhanced acoustic damping of an excited body-borne sound and reduced sound sensations.
  • a regular chair the user's full weight is under high pressure mainly applied to only the seating area of the chair or large parts of the body are in direct contact with the chair.
  • strong mechanical coupling between the user's body and the chair is generated due to a high contact pressure or a large contacted area, respectively. Any produced body-borne sound will thus be preferably conducted to the ground via the frame of said chair or base. Therefore, the user's body should be more isolated or even fully decoupled from the chair.
  • the vibrating parts are directly attached to the chair or other kind of bases, and cannot be separately used.
  • the objective problem of the invention is therefore to provide an enhanced body-borne sound experience. Furthermore, the excitation of body-borne sound should be distributed all over the body to increase the body-borne sound sensation and the efficiency of the body-borne sound excitation.
  • the invention solves the objective problem by providing a sound chair as defined in claim 1 and a sound transmitter module as defined in claim 12.
  • a sound chair enables to physically feel the sensation of music and other vibrations by comprising: a chair comprising a chair frame, a seat area, and an optional kneeling area; and at least two sound transmitter modules detachably connected to the chair, wherein at least one of the sound transmitter modules is adapted to transmit sound directly into the chair via structure-borne sound (e.g. within the physical structure of a human body as so-called body-borne sound). Furthermore, at least one of the sound transmitter modules may be adapted to transmit sound directly into the chair via a direct mechanical connection to the chair frame.
  • a sound transmitter module comprises a loudspeaker adapted to generate sound and a holding element adapted to attach the loudspeaker to an external attachment position, wherein the sound transmitter module further comprises a contact plate, wherein the contact plate is adapted to transmit the sound generated by the loudspeaker to a specific part of a human body which is in contact with the contact plate.
  • a sound transmitter module according to the present invention may further comprise a frame adapted to (directly or indirectly) hold the loudspeaker (or a multitude of loudspeakers).
  • the contact between the contact plate and a specific part of a human body can be directly (i.e. on the bare skin) or indirectly via the clothing of a user (e.g. textiles, shoes, socks). Furthermore, the contact can be established by intermediate means positioned between the contact plate and the specific part of a human body. Intermediate means could be, for example, rubber pads, any kind of hygienic protection or sound-carriers (e.g. sound-carrying gels).
  • the sound transmitter module generates a body-borne sound sensation inside a user's body (e.g.
  • body by exciting, for example, acoustic waves travelling along the skin, within the soft parts of the human body and/or via conducting through the bones.
  • body may also include the clothes and other body-like objects (e.g. prostheses).
  • the invention is based on the finding that the local coupling of a user's body to a chair can be reduced by providing a smaller seating area with reduced body contact region (e.g. a sitting roll providing a minimized seating area instead of the typically wide seating area of a regular chair) or by reducing the contact pressure between the user's body and the chair (e.g. in a stand seat, in which the seating area (e.g. a seating plate) supports the weight of the user only partially).
  • the local coupling can be reduced by distributing the user's weight to at least two distinct support areas: a seat area to accommodate the posterior of the user and a kneeling support area to accommodate at least a part of the legs of a user (e.g.
  • the weight of a user can thus be distributed to at least two localized contact areas on the chair. This reduces the local coupling between the user's body and the chair and leads to reduced mechanical damping of body-borne sound within these regions.
  • Seat area and kneeling area accommodate only a fraction of the weight of the user's body while the total contacted area is relatively small compared to a conventional (easy)chair as sound chair base.
  • sound transmitter modules according to the present invention can be used individually without requiring a chair as a basis.
  • the intensification of the body-borne sound sensation is achieved by distributing the body-borne sound excitation all over the body of a user.
  • the sound transmitter modules can then be applied for using them without a chair or on any seating furniture as, for example, chairs, sofas, stools, or kneeling benches.
  • any standing freely during use only the feet of a user are in contact with the ground and ground coupling can be neglected compared to other body-borne sound excitation devices like conventional sound chairs as any excited body-borne sound is transmitted to the feet of the user before it can be damped by the ground.
  • the seat area and the kneeling area are mechanically connected by a chair frame for a, preferably tilt-free, set up of the chair on the ground.
  • the chair frame can provide further contact plates to additionally support the user inside the chair.
  • At least one of the sound transmitter modules can be adapted to transmit sound directly into the chair via a direct mechanical connection to the chair frame.
  • Said sound transmitter module can also provide a contact plate adapted to transmit sounds indirectly into the chair via structure-borne sound over the body of a user (i.e. via body-borne sound).
  • the body-borne sound experience can be further enhanced by spatially distributing sound transmitter modules to different parts of the user's body.
  • the produced body-borne sound can thus be physically coupled and guided to the whole rest of the body of the user preferably via waves travelling along the skin and in-body transmission via the bones.
  • the distributed sound transmitter modules are not directly coupled to the chair (i.e. indirectly coupled via the body of the user) the efficiency of the body-borne sound excitation can be enhanced.
  • a direct mechanical excitation of the chair by all sound transmitter modules is not required and damping via ground coupling is reduced.
  • the present invention differs from prior art sound chairs by including individual sound transmitter modules, which can be attached to a user's body. Because the sound transmitter modules can be used independently of each other, this allows the user to use the sound transmitter modules on a base (i.e. a chair), but also enables use off or without a sound chair according to the present invention, for example, while sitting on a sofa or lying on a bed.
  • the loudspeakers comprised by the sound transmitter modules may receive audio inputs from an audio source through an amplifier to generate corresponding sound waves which are then transmitted to parts of the user's body through surfaces contacted by contact plates. Such delivery of vibrations enhances the user's experience of the sounds (e.g., music, frequencies, binaural beats) and can support the user to achieve a state of increased focus, relaxation or increased energy.
  • the chair frame can be a solid frame, stand or chassis.
  • the bottom side of the chair frame comprises three or four chair legs on which it can rest on the ground. More preferably, the bottom side of the chair frame comprises two rockers on which it can rest on the ground.
  • the seat area and a kneeling area of the chair are preferably facing in a direction opposite to the ground. They are preferably installed at the upper region of the chair frame of the chair (i.e. located opposite to the bottom side of the chair).

  • the sound is produced via a loudspeaker.
  • the sound can be audible or non-audible (ultrasound, infrasound) to a human.
  • the sound transmitter modules are detachably connected to the chair.
  • they can be attached to different parts of a human body thus that the produced sound is preferably transmitted indirectly into the chair (i.e. via the body of the user) during use of a sound chair according to the present invention.
  • At least one of the sound transmitter modules may be adapted to transmit sound directly into the chair via a direct mechanical connection to the chair.
  • the chair is a kneeling chair, a kneeling seat or a balance chair.
  • a kneeling chair is a chair where a person sits with its legs bend in a triangular fashion. The corners of that triangle are the posterior of the sitting person, their knees and their feet. Characteristically, parts of the person's weight are supported by a seat plate as seat area and a kneeling plate as kneeling area to support the knees (or a related part of the legs) of a person.
  • a kneeling seat is a special type of a kneeling chair where the shins of a user are oriented more or less parallel to the ground (angle of inclination approximately between 0° to 20°).
  • a kneeling chair In a kneeling chair the shins of a user are inclined to a predefined angle of about 20° to 80° from vertical (opposed to 90° in a normal chair). With lower angles, more of the user's weight is typically supported by parts of the legs instead of mainly the posterior. In addition to such a kneeling position, a balance chair further enables the user to lie down while being supported at more than two support areas. Typically, within a kneeling chair the person's weight is at least supported by a seat plate as seat area and a kneeling plate as kneeling area (can also be called leg support area). In an alternative embodiment of the invention, a common chair (with or without backrest) can also be used for seating in combination with one or more individual sound transmitter modules.
