Problems solved by technology

In fact, it should be noted that the intake valve always opens and closes faster, more precisely the exhaust valve tends to have some hysteresis in its interaction with the air flow, since it is restricted (intake or exhalation of air) ) incentive is rapid, so that the performance of the musicians is even more damaged
Also, in such an instrument, where the reed is excited first and then only the exhaust valve opens, there is a danger of opening lag, which is obviously detrimental to the player's performance

Embodiment Construction

[0038] figure 1 An accordion is shown, generally numbered 1, comprising a series of reeds, each of which is guaranteed to sound a note by itself. However, only preferred applications of the present invention are referred to here, and not all applications, and the present invention can be used in various types of wind instruments including free reeds, such as harmonicas.

[0039] According to the traditional way, the accordion 1 comprises two half bodies 2 and 3, which are connected substantially by a folding box 4, which defines a variable volume storage tank according to the relative positions of the half bodies 2 and 3. Air chamber 5.

[0040] Each half 2 and 3 includes at least one saddle 10 having a series of relief-shaped profiles, or cells, each forming a passage for air flow, relative to which a A free reed. Figures 2 and 3 show an example embodiment of a chamber 11 opposite to which a free reed 12 is placed. Apparently, the chamber 11 forms a passage, the air flowi...

Abstract

The invention concerns a musical instrument with free reeds comprising, for each reed (12), an intake box (16) and a delivery box (25) connected by a passage (30) whereat the reed (12) is arranged, the check valves (18, 20) of each intake box (16) are coupled so that, when one of the valves is open, the other valve is closed, and inversely, and the check valves (27, 29) of each delivery box (25) are coupled so that, when one of the valves is open, the other valve is closed and inversely. Further, for each of the intake (16) and delivery (25) boxes associated with a reed (12), at least a closure element (13) is mounted, in a first position, to close at least an opening (17, 19, 26, 28) of an intake (16) or exhaust (25) box.

Description

technical field [0001] The present invention relates to the technical field of so-called "free-reed" wind instruments, such as harmonicas and accordions. Background technique [0002] These so-called free-reed instruments differ from wind instruments with tight reeds, such as the clarinet or saxophone, in which the sound-producing reed is held tightly between the player's lips by a mouthpiece nearby. [0003] Musical instruments with free reeds generally have a body that includes a folded box made up of a series of identically defined air passage cells. The body of the instrument also includes a device for directing the air directly or indirectly blown in by the player into the direction of the chamber. Each reed of the instrument is arranged with a chamber in such a way that a flow of air sucked or pressed into the chamber excites the reed, causing the reed to vibrate, thereby producing the sound. [0004] In general, the same reed cannot be excited by a unidirectional f...
