An accordion includes a right hand play side, a left hand play side, a bellow, four rows of buttons, and two rows of buttons. The four rows of buttons include a first column to which first continuous four pitches are assigned, a second column to which second continuous four pitches are assigned, and a third column to which third continuous four pitches are assigned. The two rows of buttons include a first column to which first continuous two pitches are assigned, the first continuous two pitches being continuous from or to the first continuous four pitches, a second column to which second continuous two pitches are assigned, the second continuous two pitches being continuous from or to the second continuous four pitches, and a third column to which third continuous two pitches are assigned, the third continuous two pitches being continuous from or to the third continuous four pitches.

An accordion includes a right hand play side, a left hand play side, a bellow provided between the right hand play side and the left hand play side, and four rows of buttons provided on at least one of the right hand play side and the left hand play side. The four rows of buttons include a first column to which first continuous four pitches are assigned, a second column, provided adjacent to the first column, to which second continuous four pitches are assigned, the second continuous four pitches being adjacent to the first continuous four pitches, and a third column, provided adjacent to the second column, to which third continuous four pitches are assigned, the third continuous four pitches being adjacent to the second continuous four pitches.

This invention relates to a caging device for the transforming key terminals of key-type accordions including a frame and a caging unit, in which, the frame is set on the sound board, the caging unit includes two sets and each one includes an inflexion moving plate, an upper shift lever, a roller, a lower shift lever, an inflexion valve plate, a caging frame, a swing rod, a spring and a swing rod base, in which, one end of the inflexion moving plate is connected with the inflexion key, the other end is hinged with the end of the valve plate, one end of the caging frame is fixed to the roller, the other end is hinged to the swing rod hinged with the base, which is installed on the sound board, the spring is jacketed on the swing rod and the best position can be arrived when an inflexion key is pressed.

The object of the invention is a single dual reed module, particularly for an instrument of the accordion type using two directions of air flow, characterized in that it comprises, for each note, a single fixed tongue carrier (32) with a window (34) and a tongue (36) connected to this tongue carrier and comprising at least one tongue (42) disposed in line with this window, as well as at least one associated movable element (44), disposed laterally relative to said tongue and adapted to take a first position for a first direction of air flow by providing an interstice between this movable element and the edge of the tongue such that this blade vibrates to emit said note in this first direction of air flow, and a second position symmetrical to the first position relative to the plane of the tongue for the second direction of air flow, by also providing an interstice such that the tongue vibrates to emit the same note in this second direction of air flow.

The invention discloses an accordion sound hole cover capable of being automatically leveled. The accordion sound hole cover capable of being automatically leveled is that a key rod slot connected with a key rod is processed in a sound hole cover body; the section of the key rod slot is in a shape of a revered trapezoidal structure of which the bottom side is relatively short; a transverse bulge which is vertical to the key rod slot is arranged in the middle part of the key rod slot. According to the accordion sound hole cover capable of being automatically leveled, the key rod slot is processed into the trapezoidal structure; the key rod can automatically fall down to the center of the key rod slot according to the self-fastening principle while being assembled to the sound hole cover; the transverse bulge vertical to the key rod is arranged in the middle part of the key rod slot; the key rod pressed into the key rod slot can only be in contact with the transverse bulge according to the lever supporting principle, and therefore, the sound hole cover can be automatically leveled, and the force on an area in which the bottom surface of the sound hole cover is in contact with a sound hole plate is uniform; in addition, stressing points of each sound hole cover are the same. The accordion sound hole cover adopting the structure above is able to automatically level and center, is simple in structure and convenient to operate, can greatly increase the product quality and production efficiency, and has obvious economic value and social value.

The invention discloses an integrated accordion bass machine, which comprises a top piece, a rolling thread, a top piece nail, a stake and a push rod. The top sheet is arranged in two layers, and all chord sound top sheets are processed with 4 top sheet nail mounting holes, and each chord sound top sheet is equipped with 3 top sheet nails corresponding to the controlled piles. The present invention adjusts the arrangement positions of the thread rolling and the top piece by integrating and optimizing the structure of the main transmission parts of the bass machine, greatly reduces the assembly difficulty of the bass machine, improves the assembly efficiency and the assembly quality; and unifies the top plate The specifications of components such as thread rolling and thread rolling are conducive to batch processing of parts, and the answer improves production efficiency, and the parts are highly interchangeable, convenient and fast to assemble, high in precision, and low in maintenance costs, which can greatly improve the product quality and production of bass machines. Efficiency has significant economic and social value.
