Definitions

  • the present invention relates to an improvement to simplify the construction of a harmonica while facilitating its maintenance and improving its sound performance through an optimization of its sealing against air leaks.
  • harmonicas of the prior art suffer from a poor performance on the a Vogellic plane, and therefore consequently on the sound level, in particular because of the very penalizing air leaks which take place at the level of the mouth of the instrument between the comb, the blade holders and the caps and because the said caps do not exert all along the mouth face pressure sufficient to ensure sealing between these elements between them.
  • This conventional embodiment adopted by the majority of existing products actually provides at the end zones of the harmonica plating satisfactory and therefore a satisfactory seal against air leakage between the comb, the blade and the covers with regard to the zones situated in the immediate vicinity of said screws, therefore on the one hand at the level of the air ducts supplying the bass blades of the instrument and, on the other hand, at the air ducts supplying the blades treble of the instrument.
  • the present invention therefore aims to obviate these drawbacks and, to achieve its objectives, it aims first of all to ensure a quick and easy disassembly of the blade holder for tuning and cleaning operations of the harmonica while ensuring in addition, an optimum seal is provided all along the mouth face between the covers, the blade plates and the corresponding bearing faces of the harmonica comb or base plate against which the said plates supporting the sound blades of the harmonica are applied; instrument.
  • the invention proposes a particular design of the covers and clamping means associated with them, said clamping means being implanted as close as possible to the mouth face at different points along the length of the harmonica and not located only at the end zones of the hoods as is the case in the harmonicas of the prior art.
  • each of the two covers pivots around the end of its legs bearing against the blade holder on the side of the roof of the instrument until, in the manner of the two jaws of a pincer, by cantilever effect, all along the mouth face of the instrument the lip of each of the two covers are strongly applied against the blade holders by pressing them against the comb so as to ensure a perfect seal between all these elements including in the central part of the mouth face where the devices of the prior art fail.
  • the invention proposes arrangements of said covers and if necessary the comb designed to ensure optimum supply of air to said blades, in particular with regard to the serious sound waves that require a high airflow for their vibrations.
  • the invention also proposes a particular conformation of the air circulation ducts supplying the sound strips aimed both at allowing the passage of powerful clamping screws through certain lateral partition walls of the channels as well as at optimizing the flows of the air flows in said channels.
  • the improvements proposed in this invention are applicable to all types of harmonicas as well harmonicas of the low type, tremolos or diatonic which each air channel feeding one or more sound blades is connected directly to a single mouth hole that harmonicas of the chromatic type having a sliding or pivoting air distributor for selectively sending to a first channel, feeding at least one blown blade and at least one aspirated blade, or to a second channel, also supplying at least one blown blade and at least one blade sucked, the air sucked or the air blown by the player into a mouth hole common to these two adjacent air channels.

  • the bed can advantageously be made in two parts assembled together, for example at the mean longitudinal plane Pm of the instrument, by gluing, clipping welding or any other medium and in particular simply by screwing the clamping screws hoods that take the comb sandwiched between them, this mode of assembly with the advantage of keeping the possibility of separating at will the two half box springs for easy cleaning.

  • Such an arrangement also makes it possible to give priority to the ability of the instrument to produce the natural basic notes of each of the blades under the aspirated or blown air streams which correspond to their specificity or, on the contrary, to favor the ability of the instrument to produce so-called "altered" notes that require the sound blades to be solicited under suction or blown air flows in the opposite direction to those corresponding to their specificity.
