Definitions

  • the invention relates to a shutter for facilitating the emission of predetermined notes from a transverse flute or the like.
  • a shutter for facilitating the emission of predetermined notes from a transverse flute or the like.
  • the object of the invention is to propose a shutter which facilitates the emission of said notes. This object is achieved by the fact that, according to the invention, there is at least one auxiliary resonator in the obturator opening out onto the air column and produced in the form of a chamber whose length is specifically granted to facilitate '' issuance of at least one predetermined note from the instrument.
  • the length of the chamber is granted so that its natural frequency is a binary logarithm of the frequency of the fundamental of the predetermined note.
  • the specific resonator is tuned to a sensitive harmonic (one of the upper octaves) of the fundamental of the note in question.
  • the room is advantageously designed in the form of a room of variable length which is adjusted for tuning.
  • This adjustment can be fixed by one means or another depending on the adjustment means if one wishes an immutable agreement; it can be left free if you want to be able to change it later, if only to adapt it to the different tuning forks in use.
  • the specific resonator (s) consist of one or more concentric chambers, advantageously of adjustable length.
  • the shutter is honeycombed with holes constituting the specific resonators.
  • the shutter comprises an internal piston sliding in an adjustable manner in an annular piston, the front end of which has a choice of a planar shape, a convex flared shape, a concave flared shape, a stepped flared shape , a diverging frustoconical form, or a converging frustoconical form.
  • Figure 1 shows a transverse flute 12 with its mouth 13 and, to the left of the mouth hole, a cavity traditionally closed by a cork stopper 14 clamped between two metal plates 15 mounted on a threaded rod 16 whose end 17 screws into a knurled button 18.
  • the cork stopper 14 To be waterproof, the cork stopper 14 must be forced into this conical part of the mouth.
  • the coefficient of friction of the plug 14 being greater than the torque delivered by the knurled button 18, the system does not work in the direction of elongation of the cavity (action of screwing the button). The system does not work in the other direction either (unscrewing action), because in this case the button is released without modifying in any way the volume of the cavity in question.
  • the invention proposes to replace this fixed plug with a system of one or more specific resonators.
  • the conventional plug is replaced by a plug made up of one or more concentric pistons sliding in one another and thus forming concentric chambers of adjustable length.
  • a plug made up of one or more concentric pistons sliding in one another and thus forming concentric chambers of adjustable length.
  • a surface 25 with two or more sides makes it possible to rotate the assembly to adjust the position thereof while a vernier of the “Palmer” type produced on this surface pinpoint its position.
  • the central piston 20 slides in the annular piston 19 (a seal 26 being provided).
  • a micrometric thread 27 cooperates with the rod of the annular piston 19 for adjusting the relative position of the two pistons: a button 28 provided with a "Palmer” type vernier allows fine adjustment.
  • the shutter of the invention comprises a main shutter 29 mounted with a seal 30 in the end of the flute body in a fixed position or, preferably adjustable by means of a device not shown.
  • the main shutter 29 is honeycombed with holes 31, cylindrical (fig. 7), hexagonal (fig. 8) or others, only one of which has been shown in FIG. 6.
  • the bottom of each hole consists of a piston 32 adjustable allowing to tune the length 1 of the hole on a specific frequency improving the emission of a predetermined note.
  • each of these holes 31 is carefully tuned to a sensitive harmonic of the fundamental frequencies of the flute.
  • each note thus has its own resonator 31.
  • this system makes it possible, by slightly varying the length of the resonators 31, to individually tune the timbre and the octave ratios of each note of the flute within certain limits.
  • the length of the resonators 31 can be fixed, in this case the instrument is constructed in a single tuning fork. One can even then make the plug 29 in molded plastic, the holes 31 being molded to a precalculated length.
  • This embodiment gives compared to the previous a greater fixity of the notes, which will make it particularly appreciated by beginner students. Confirmed artists may prefer the first embodiment which allows greater personalization of the instrument.
  • FIG. 6 illustrates a variant of FIG. 2, in which an internal piston 120 can slide inside an annular piston 119, which itself can be mounted sliding or not (as shown in FIG. 6).
  • the originality of this variant resides in the convex flared shape given to the front end of the annular piston 119, analogous to a trumpet horn. Thanks to the movable piston 120 adjustable by the knurled knob 128 the length of the chamber on a harmonic of the fundamental note of the flute; experience shows that the emission of both this fundamental note and other notes is facilitated. Everything happens as if, for a given note other than the fundamental note, the air column found itself the right length of chord by taking "support" on the area of the flared part corresponding to the right length of room.
  • FIGS. 7 to 10 show different shapes which can be given to the front part of the piston 119: a convex flared shape stepped in FIG. 7, a concave flared shape in FIG. 9, a divergent frustoconical shape in FIG. 8, a converging frustoconical shape in FIG. 10.
  • a convex flared shape stepped in FIG. 7 a concave flared shape in FIG. 9, a divergent frustoconical shape in FIG. 8, a converging frustoconical shape in FIG. 10.
