- This set of pressures is based on the formation of an overpressure in the chamber 131 at the level of the blown reed 111 when the user blows in a configuration intended to make the sucked reed 121 vibrate.
- the blast creates a overpressure in chamber 131.
- overpressure at the level of the blown reed 111 blocks the latter, while the overpressure at the level of the sucked reed 121 will cause the latter to vibrate.
- the air circuit 170 in the chamber 131 in this configuration has less resistance passing through the sucked reed 121 than through the blown reed 111. Therefore, the breath makes it possible to vibrate the sucked reed. 121.
- the additional plate 150 makes it possible to limit air leaks at the base of the blown reed 111, and therefore to compact the air flow 170 in the chamber 131 when the user blows to trigger the sucked reed 121.
- the additional plate 150 also limits or even eliminates the spin effect.
- the additional plate 150 allows, when the user blows to trigger the sucked reed 121, to reduce the oscillatory space 112 of the blown reed 111 and therefore helps to block it and trigger the reed. sucked reed 121.
- FIG. 13 This situation is for example illustrated in FIG. 13.
- the air flow circulates via the sucked reed 121 while the user blows from the chamber 131, this then allowing the vibration of the sucked reed. 121 while blocking by said set of pressures the blown reed 111.
- Figure 11 the case of a normal breath is illustrated in Figure 11, the user blows air from the chamber 131 and thus vibrates the 'blown reed 111, this when he does not have his tongue in a particular way.
- the present invention facilitates the triggering, that is, the setting in vibration, of the "opposite reed", the reed blown by sucking, or the reed sucked by blowing.
- Figures 11 to 14 illustrate normal tripping situations and opposite tripping situations.
- Figure 11 illustrates the case where the user blows into the chamber vibrating the blown reed.
- FIG. 12 illustrates the case where the user sucks from the chamber, vibrating the sucked reed.
- Figure 13 illustrates the situation opposite to that of Figure 11.
- Figure 13 illustrates the case where the user blows into the chamber so as to vibrate the suction reed.
- Figure 14 illustrates the situation opposite to that of Figure 12.
- Figure 14 illustrates the case where the user aspirates from the chamber so as to vibrate the blown reed.
- the present invention facilitates the handling of a harmonica and allows experienced players to manipulate notes not present on the instrument in a simple, easy and reproducible manner. Indeed, the issue of reproducibility is essential.
- the present invention reduces the number of parameters influencing whether or not these particular scores are obtained.
- the cooperation between the additional plate with the first plate is similar to the cooperation of the box spring according to the present invention with the second plate. It is the implementation of the same inventive concept applied symmetrically to two elements of the harmonica that achieves this ease of play and reproducibility.
- This reproducibility is linked in particular to the improvement of the partitioning of the rooms, that is to say to the improvement of the control of the air circulation in the rooms.
- the present invention makes it possible to make it easier to obtain certain musical notes, for example as soon as the instrument is purchased, and advantageously without requiring long and difficult learning for the user.
- each element of the present invention provides something independent of the others, and combined together they maximize the ease of playing of the harmonica according to the present invention.
- each element of the present invention improves the seal inside the chamber and compacts the airflow a little more, so the pressure plays are sharper, and therefore the reeds more responsive.
- the base and the additional plate according to the present invention have technical advantages independently of one another, and when combined together they maximize the ease of playing of the harmonica according to the present invention.
- the box spring and the additional plate act in synergy with each other to improve the tightness inside the chamber and to compact the air flow a little more, so the pressure plays are more crisp, and therefore more responsive reeds.
- the harmonica according to the present invention can either comprise one of the base and the additional plate, or include the base and the additional plate.
