Definitions

  • the field of the invention relates to musical devices and methods for playing musical sequences.
  • US5,349,129 describes an electronic musical device allowing the generation of musical notes or phrases.
  • This device proposes to place modular elements on a support. Each modular element is associated with a musical note. When playing, the device plays the notes one after the other depending on the modular elements placed on the support and their order on the support.
  • this device can only generate one melody at a time.
  • this device does not allow the child to modify the composition in real time. He must create a composition, listen to it, then modify it once the sequence has been generated.
  • US8,420,923 describes a children's musical device in which a plurality of musical tracks can be played simultaneously. Each musical track corresponds to the score of a musical instrument in a symphonic composition.
  • the device comprises a plurality of parts each representing a musical instrument. When the user places a piece on a particular support, the musical sequence associated with that instrument is played. The user can then add or remove pieces from the media to stop or add a music track associated with an instrument.
  • this device proves useful for the identification or recognition of the sound of an instrument in a symphonic composition, the disadvantage of this device is that the user remains passive and does not have the possibility of modifying the track. an instrument or to participate in musical creation.
  • US 6,353,168 B1 provides a musical toy comprising blocks to be inserted into cavities on a support structure, including sensors for detecting the insertion orientation of the blocks. Each side of a block is associated with a particular section of the melody with different orchestration.
  • the present invention aims to resolve the aforementioned drawbacks.
  • the insertion of at least two pieces into their respective receptacle activates the sound diffusion by the audio system of at least two musical tracks given simultaneously.
  • Said given musical tracks being selected from a set of musical tracks according to each of the orientations of said determined pieces, and optionally according to each receptacle in which said pieces are inserted.
  • the device further comprising a calculation system to ensure the synchronization of the musical tracks broadcast simultaneously.
  • the activation of the sound diffusion is carried out by a computer receiving indicators of orientation and/or presence of one or more part(s) within a receptacle of the frame.
  • the calculator can, for example, be integrated into the audio system.
  • the computer is a computer separate from the audio system. In the latter case, the computer delivers instructions aimed at communicating a broadcast mode to the audio system, such as activating the sound broadcast of a track or making it silent.
  • the calculator receives or interrogates at regular intervals digital statuses from a memory representative of the presence or not of one or more part(s) in a receptacle and its orientation in the receptacle. This memory is, for example, coupled with the detectors to record the measurements of each detector at regular intervals. Said calculator or the calculation system is connected to the audio system.
  • a first advantage is to allow the synchronized sound diffusion of two musical tracks selected from the placement and orientation of a part in a receptacle, in particular without changing the contact face. The user can thus modify one of the musical tracks by swapping the orientation of a piece.
  • a second advantage is to synchronize the musical tracks.
  • the second track is played so that the playback locations of the first and second tracks match.
  • the second track is played in such a way that its notes blend into the melody of the first track.
  • each receptacle comprises a reception cavity forming a geometric shape intended to accommodate a part of a predefined geometric shape, preferably in several orientations of the part.
  • the frame comprises recesses for removably accommodating a receptacle, and in that each receptacle comprises a reception cavity forming a geometric shape intended to accommodate a part of a predefined geometric shape, preferably according to several orientations of the room.
  • An advantage is being able to design the parts in such a way that a part can only cooperate with a single receptacle.
  • the plurality of detectors includes a plurality of Hall sensors and the indexing elements include permanent magnets.
  • An advantage of a permanent magnet and Hall effect sensors is to provide a means of detection which is not accessible on the surface of a part or the frame.
  • the indexing elements and detectors are buried and inaccessible to the user. The risk of breakage is thus reduced, particularly when the user is a young child.
  • Another advantage is to provide a “passive” detection system, that is to say without emission of waves, light or signal between the three-dimensional part and a detector.
  • the device comprises display means, the calculation system being configured so that the display means emits information relating to the orientation of a part in a receptacle.
  • An advantage is being able to provide the user with information on which track is currently being broadcast.
  • the device includes a memory comprising a set of musical tracks or a compatible connector for receiving information from such memory.
  • the actuation of sound broadcasting by the audio system of a selected musical track may include an automatic modification of the volume setting of said musical track on the second volume for its broadcasting.
  • the musical device comprises a plurality of parts adapted to cooperate with said receptacles.
  • each part comprises a permanent magnet arranged between the center of the part and a radial end of said part.
  • distal end is meant a zone not including a center of rotation of the part around which the part rotates to switch between two orientations in the receptacle.
  • the invention relates to a method for broadcasting several musical tracks simultaneously and in a synchronized manner.
  • the sound broadcasting of the second selected musical track is started from the temporal location of the first musical track being broadcast.
  • An advantage is to allow, when a first track is broadcast, the sound broadcast of a second track in a synchronized manner with the first track so as to combine these two tracks without having to carry out calculations on how to trigger the second track so that it can be superimposed on the first.
  • a simple command allows you to automatically broadcast, with a surprisingly short response time, a second track which will combine perfectly with the first track.
  • the sound broadcast of the third selected musical track is started from the temporal location of the second musical track being broadcast.
  • stopping the sound broadcasting of the first musical track is carried out by automatically modifying the volume adjustment of said first musical track from the second volume to the first volume to stop its sound broadcasting as soon as said first track music is no longer selected.
  • An advantage is being able to modify one of the tracks without interrupting the playback of a second track. This method advantageously allows you to modify one track by another and be able to notice the difference on an overall symphonic melody.
  • the method includes a step of simultaneously launching all the tracks of the set of musical tracks, preferably from the same temporal location.
  • the volume of each track is individually adjustable between at least a first volume and a second volume, the first volume corresponding to a zero volume preventing its diffusion and the second volume having a predetermined value generates its sound diffusion.
  • the sound broadcasting of a selected track comprising a sub-step of automatically modifying the volume of said track, from the first volume to the second volume for its sound broadcasting.
  • This embodiment advantageously makes it possible to improve the response time between the selection of the musical track and its sound broadcast in a manner synchronized with the first sound track.

  • a device 1 intended for children may include shapes of receptacle 11 including star shapes , square, crescent moon.
  • a device 1 intended for adults may include more neutral forms.
  • the receptacles 11 inserting into recesses 4 of the frame 2 therefore make it possible to modulate the musical device 1.
