Definitions
- the field of the invention relates to musical devices and methods for playing musical sequences.
- buttons For example, devices are known that allow generation when the child presses specific buttons. However, children are content to associate a button with a sound and do not develop their musical awareness.
- US Pat. No. 5,349,129 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. During reading, the device plays the notes one after the other according to the modular elements placed on the support and their order on the support.
- this device only allows you to generate one melody at a time.
- this device does not allow the child to modify the composition in real time. He must make a composition, listen to it, then modify it once the sequence has been generated.
- US8,420,923 describes a musical device for children 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 medium, the musical sequence associated with that instrument is played. The user can then add or remove parts from the medium to stop or add a musical track associated with an instrument.
- the present invention aims to resolve the aforementioned drawbacks.
- the invention relates to a musical device comprising:
- ⁇ a plurality of receptacles to accommodate three-dimensional parts each having a face able to switch between at least two orientations in said receptacle; each part comprising an element for indexing the orientation of the part among the at least two orientations,
- each detector being associated with a receptacle to determine the orientation of the workpiece via the detection of an indexing element in its receptacle

- the sound diffusion is actuated by a computer receiving indicators of orientation and / or presence of one or more part (s) within a receptacle of the frame.
- the computer 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 broadcasting mode to the audio system, such as activating the sound broadcasting of a track or silencing it.
- the computer receives or interrogates at regular intervals digital statuses of a memory representative of the presence or absence of one or more part (s) in a receptacle and of its orientation in the receptacle. This memory is, for example, coupled with the detectors to record at regular intervals the measurements of each detector.
- Said computer or the computing system is connected to the audio system.
- a first advantage is to allow the sound diffusion in a synchronized manner of two musical tracks selected from the placement and the 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 switching the orientation of a room.
- a second advantage is to synchronize the musical tracks.

- the automatic modification of the volume control respectively said first or second selected music track from the first volume to the second volume for the sound diffusion.
- An advantage is to allow, when a first track is broadcast, the sound diffusion of a second track in a synchronized manner with the first track so as to combine these two tracks without having to perform calculations on how to trigger the second track. so that it can be superimposed on the first.
- a simple command makes it possible to automatically broadcast, with a surprisingly reduced response time, a second track which will combine perfectly with the first track.
- the method further comprises the steps of:
- the third music track is played simultaneously and in synchronization with the second music track.
- the sound broadcasting of the third selected musical track is started from the temporal location of the second musical track being broadcast.
- the stopping of the sound diffusion of the first musical track is carried out by the automatic modification of the adjustment of the volume of the said first musical track from the second volume to the first volume to stop its sound diffusion as soon as the said first track music is no longer selected.
- One advantage is that you can edit one of the tracks without interrupting playback of a second track.
- This method advantageously makes it possible to modify one track by another and to be able to observe the difference on a global symphonic melody.
- the method comprises a step of simultaneously launching all the tracks of the set of musical tracks, preferably from the same time 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 distribution 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 distribution.
- This embodiment advantageously makes it possible to improve the response time between the selection of the musical track and its sound distribution in a manner synchronized with the first sound track.
- the invention relates to a musical device comprising:
- ⁇ a plurality of receptacles to accommodate three-dimensional parts each having a face able to switch between at least two orientations in said receptacle; each part comprising an element for indexing the orientation of the part among the at least two orientations,
- each detector being associated with a receptacle to determine the orientation of the part via the detection of an indexing element in its receptacle, said detectors being hall effect sensors for measuring at least one characteristic of a magnetic field of a magnet included in a part and forming the element of indexing in order to evaluate the position and / or the relative orientation of each magnet with at least one detector;
- ⁇ at least one audio system for generating an audible signal resulting from a mixing at least two music tracks data (Mi, M2), said data being automatically selected music tracks from a set of musical tracks according to the position and / or the evaluated orientation (s) of the magnet of each part inserted into a receptacle.
