Definitions
- the present invention relates to the elements for the construction of a harmonica module capable of producing at least one musical note, in order to obtain all the modules necessary for the realization of a complete harmonica.
- a current harmonica essentially consists of a support (called “bed base” or “comb” by those skilled in the art) in which a plurality of chambers juxtaposed next to one another and opening on the two opposite faces of the support are made, and two plates each having as many slots as chambers, each slot being associated with at least one vibrating blade to produce at least one note by displacement of air blown or sucked.
- the two plates are respectively fixed on the opposite faces of the support so that each blade is in the axis of a chamber.
- FR 2 344 906 discloses an instrument such as a harmonica which consists of an assembly of modules. Each module has a blade whose vibrations make it possible to obtain a note of music.
- This structure has the following major disadvantage: when the blade is broken or damaged or the like, it is very difficult to change, replacement requiring tools and expertise. It is therefore necessary to replace the entire module in its entirety.
- the object of the present invention is, contrary to the prior art, to produce an element for the construction of a harmonica module, and not a module in its entirety, capable of producing at least a musical note, which overcomes the disadvantages mentioned above.
- the subject of the present invention is an element for the construction of a harmonica module capable of producing at least one musical note, characterized in that it comprises:
- a basic piece including a first wall and a second wall, said walls being substantially parallelepipedal rectangles of equal length, and
- At least one first hermaphrodite male-female interlocking system At least one first hermaphrodite male-female interlocking system
- FIG. 1 is a schematic perspective view of a first embodiment of an element according to the invention for the construction of a harmonica module capable of producing at least one musical note
- FIGS. 2 and 4 show two cross-sectional views of the element according to the invention in the embodiment according to FIG. 1, respectively referenced II-II and IV-IV in this FIG. 1,
- FIG. 3 represents a cross-sectional view of the element according to the invention in another embodiment, this section being taken in the same plane as the section according to FIG. 2,
- FIGS. 5 to 7 show an industrial embodiment of an element according to the invention for the construction of a harmonica module capable of producing at least one musical note
- FIG. 5 being a perspective view of this Figure 6 (A) and (B) represent, juxtaposed and close to one another, two identical elements according to the invention, one having undergone a 180 degree rotation with respect to the other
- FIG. 7 being a perspective view of a harmonica module according to the invention constituted by the assembly of two identical elements according to the invention. the invention.
- the present invention relates to an element for the construction of a harmonica module capable of producing at least one musical note, and which makes it possible to construct all the modules necessary for producing a complete harmonica.
- This element comprises, more particularly with reference to FIG. 1, a base part 10 comprising a first wall 1 1 and a second wall 12, these walls being substantially rectangular parallelepipedal (or comparable to such a shape in its general function) and of same length, and means 13 for associating the two walls 1 1, 12 by their length so that they form a right corner angle dihedron whose edge 14 is formed by the common lengths of the two walls.
- These means for associating the two walls 11, 12 may be of any type. An example of their preferential implementation will be given below.
- the element also comprises at least one longitudinal slot 18 made in the first wall 11 in parallel to the edge 14, this slot being adapted to receive at least one vibrating blade for producing the at least one desired musical note.
- the element furthermore comprises at least a first hermaphroditic male-female interlocking system, evoked schematically at 15 in FIG. 1, and means 17 for securing this first interlocking system 15 with the base piece 10 so that it fits into one.
- other nesting system 15 which is identical after it has been rotated 180 degrees about a direction 30 parallel to the edge 14, Figures 4 and 6 A & B.
- the first interlocking system 15 is secured to the base part 10 so that it fits into another interlocking system 15 which is identical in a direction which is both parallel to the first wall 1 1 and perpendicular to the edge 14.
- this first interlocking system 15 is secured to the base piece 10 so that it closes at least partially an end face 31 of the base piece and when it fits with another nesting system which is identical, this end face 31 is completely closed.
- the first hermaphrodite male-female interlocking system consists, as illustrated in FIGS. 4, 5 and 6, of two cubes integral with one another by a 34 of their faces while being offset with respect to each other.
- cube means a cube in the strict mathematical sense, and a block or the like having the shape of a rectangular parallelepiped.
- the means 13 for associating the two walls 1 1, 12 and the means 17 to secure the first interlocking system 15 with the base part 10 they are constituted by the fact that the base part and the first system of interlocking are made in one piece, advantageously for example according to one of the following methods: molding, 3D printing, machining.
- the element comprises a plurality of hermaphroditic male-female interlocking systems 15, identical or not, but in any case identical function as defined above with the first system interlocking, arranged on each other in planes perpendicular to a direction parallel to the edge 14.
- the element according to the invention comprises two of these systems S1, S2 which are substantially identical and symmetrical relative to a point.
- Figure 2 shows, in cross section referenced II-II in Figure 1, an embodiment as described above.
- Figure 3 shows another possible embodiment.
- the base part 10 has a substantially parallelepiped rectangular flange wall 40.
- This flange wall is perpendicularly secured to the free side of the first wall 11 opposite to that which is integral with the second wall 12, and it is situated in the same half-space defined by the first wall as the one in which the second wall is located. wall, to form an L-shaped block, the first wall 11 defining the base leg of the L, the rim wall defining the other leg of this L having a length and a width respectively equal to and less than the length and the width of the second wall 12.
- this flange wall 40 may correspond to a notch, groove, etc. made in the wall 12, so that when two identical elements according to the invention are associated as shown in Figure 3, they fit into one another to improve the sealing of the space 50 defined ci -after, so as to force almost all the air drawn or blown by the musician to pass on the vibrating blades as is well known for the production of musical notes with harmonicas.
- the element according to the invention makes it possible to produce a module, FIGS. 2, 3 and 7, which comprises two such associated elements so that the two base pieces 10 are arranged facing one another. other in contact and axially symmetrical to form a rectangular parallelepiped hollow space 50.
- the two longitudinal slots 18 made respectively in the first two walls 11 are each able to receive at least one vibrating blade for the production of at least one musical note, these blades being able to be placed inside or outside the hollow space 50, to produce musical notes by blowing or sucking the air.
- Figure 4 shows, in cross section, the first interlocking systems 15 of three modules E1, E2, E3 associated by interlocking with each other for the formation of a complete harmonica.
- the structure described above is very advantageous because, firstly, it allows the manufacturer to mass produce any type of harmonica, or on demand according to the will of a musician, for example a normal range three octaves, either a simple diatonic harmonica, a double diatonic harmonica or a chromatic harmonica, with specific note arrangements as for blues or folk, lower or higher octaves, etc.
