Definitions

  • the invention relates to an electronic accordion, comprising a treble side and a bass side and a bellows device connecting the treble side to the bass side and defining a bellows volume, the treble side and the bass side being movable relative to one another while changing the bellows volume, with a first group on the treble side of control elements and a second group of control elements is arranged on the bass side.
  • Electronic accordions are known from the prior art. In the case of electronic accordions, in contrast to conventional accordions, a sound is not generated via sound sticks, but digitally or electronically and output via a loudspeaker. By eliminating the reed blocks, electronic accordions differ from conventional ones in that the air throughput does not vary during playing. In conventional accordions, the air throughput varies by opening the different vocal flaps, so that when different individual vocal flaps associated operating elements, i.e. different keys, are actuated, a different air throughput and also a different pressure in the bellows device or in the bellows volume is set.
  • the playing behavior also called bellows dynamics
  • bellows dynamics in such electronic accordions thus differs considerably from conventional accordions, which causes difficulties for many users, in particular when emphasizing the music.
  • EP 1 752 966 A2 - ROLAND CORP [JP] - February 14, 2007 discloses an electronic accordion comprising the external structural features of an acoustic accordion.
  • the bellows valve is controlled in order to approximate the feel of an acoustic accordion.
  • EP 2 779 154 A1 - ROLAND EUROP SPA [IT] - September 17, 2014 discloses an electronic accordion with a bellows valve ( Fig. 4-6 Character 15), the position of which is electronically controlled in connection with the key actuation ( ⁇ 18). In ⁇ 16 it is also discussed how the valve opening is controlled depending on the number of notes played and the selected registers.
  • the invention is therefore based on the object of specifying an electronic accordion in which the playing behavior is improved.
  • At least one resistance device with at least one resistance element is provided, which is designed to at least partially open or close at least one opening in the bellows device as a function of a position of the at least one resistance element.
  • the invention is thus based on the idea of not only providing one opening or several openings in the bellows device, as is customary in the prior art, which lead to a constant air flow, but rather to at least partially open or open at least one opening in the bellows device by means of a resistance element . close. Due to the position of the resistance element that is assigned to the resistance device, the air throughput through the at least one opening in the bellows device is thus variable. By moving the resistance element into different positions, the at least one opening can thus be covered or closed to different extents in order to better adapt the air throughput through the opening to the playing behavior of a classic accordion.
  • the at least one opening can be completely closed or completely opened or can assume any desired value or any desired position between the completely open and the completely closed position.
  • opening opening in the bellows device
  • the term opening is not restricted to openings which are arranged directly or immediately in the bellows device. Rather, all openings that are directly or indirectly in fluid connection with the bellows device are to be understood as “openings" in the sense of the present application.
  • openings connected to the bellows device via a line structure, for example a hose are also to be understood as openings in the bellows device.
  • a pressure in the bellows volume is dependent on the position of the at least one resistance element during a game operation.
  • the air throughput through the at least one opening is dependent on the position of the at least one resistance element.
  • At least one Resistance element closes or opens the at least one opening, depending on the position in which the resistance element is.
  • the resistance element can at least partially open or close the at least one opening, so that the pressure that builds up in the bellows volume is ultimately also dependent on the position of the resistance element.
  • a preferred development of the electronic accordion according to the invention can consist in that the position of the at least one resistance element can be adjusted as a function of an actuation of at least one operating element. According to this development, a relationship is established between the actuation of an operating element and the position of the at least one resistance element.
  • the playing behavior of the electronic accordion can thus be further matched to that of a classic accordion, since in a classic accordion the pressure in the bellows volume or the air throughput through the at least one opening also depends on the actuation of the operating elements.
  • the resistance device is consequently designed in such a way that it changes the position of the at least one resistance element when an operating element is actuated. If the control element is released, the resistance element is moved back into the starting position or basic position.
  • the resistance device has at least one control device assigned to at least one resistance element, the at least one resistance element being movable, preferably displaceable, in a basic state depending on an actuation of the at least one operating element by means of the control device, is that the at least one opening is at least partially open or closed.
  • the resistance device has at least one adjusting device which is provided to move the at least one resistance element or to bring it into different positions.
  • the actuating device can move the at least one resistance element from a basic state into a position which is provided for actuating at least one operating element.
  • a position of the at least one resistance element such that the at least one opening is closed in the basic state is preferred.
  • the actuating device sets or moves the at least one resistance element from the basic state into the position that corresponds to the actuation of the at least one operating element. It is thereby achieved that, as in the case of a classic accordion, the actuation of an operating element leads to a change in the air throughput and thus to a change in the pressure in the bellows volume.
  • the at least one adjusting device is preferably designed in such a way that it can move the at least one resistance element. By moving the resistance element, it is moved over or relative to the opening, at least in sections, in order to open or close it. The resistance element can thus be pushed over the opening at least in sections in order to regulate the air throughput through the opening.
  • an opening dimension is defined for actuation of at least one operating element, which determines the extent to which the at least one opening in the bellows device is opened or closed by means of the at least one resistance element, or that an opening dimension is defined for the actuation of an operating element assigned to a subgroup of operating elements, different opening dimensions being defined for different operating elements or for different subgroups.
  • the opening dimension defines the extent to which the at least one opening in the bellows device is open or closed when an operating element is actuated.
  • the opening dimension thus defines the relative position or a relative displacement between the at least one opening or the edges of the opening and the at least one resistance element.
  • the opening dimension defines how far the at least one opening is opened or closed.
  • a separate opening dimension can be defined for each of the operating elements so that the resistance element assumes an individual position as a function of each individual operating element.
  • the at least one resistance element is moved or set by actuating the various operating elements in such a way that the opening dimension specified for the respective operating element is set when it is actuated.
  • the resistance element is set in such a way that the at least one opening is opened or closed by the corresponding opening dimension assigned to the subgroup.
  • both alternatives are also possible in addition, so that both individual operating elements are assigned individual opening dimensions and other operating elements are combined into subgroups, which in turn are assigned an opening dimension.
  • the operating elements of an octave are combined to form a subgroup.
  • the operating elements that are assigned to the same octave are preferably combined into a subgroup in this embodiment of the invention.
  • pressing one of the controls that are assigned to the same octave creates the same opening dimension.
  • the opening dimensions defined for at least two operating elements are additive when the at least two operating elements are actuated. Accordingly, the opening dimensions add up when several operating elements are actuated.
  • the at least one resistance element is consequently set in such a way that the at least one opening is opened or closed to the extent that this is predetermined by adding the opening dimensions defined for the individual actuated operating elements.
  • the electronic accordion according to the invention is further developed in such a way that a computing device is provided which is designed to receive a signal, preferably a signal generated based on an actuation of the at least one operating element, from a control device or directly from the at least one operating element.
