Description

Technical Field

[0001] This invention belongs to the field of melodica technology, and in particular relates to a wide-range melodica. Background Technology

[0002] The existing melodica works by pressing the keys, which rotates the keys at a certain angle, causing the baffles and plugs at the ends of the keys to separate from the vents. This connects the shell interface, the air intake channel of the shell, the tone holes on the reeds, the vents on the soundboard, and the exhaust port of the shell. At this time, the incoming air passes through the reeds, causing the reeds to vibrate and produce sound. There are two ways to use it: one is to play it on a table, and the other is to play it by hand.

[0003] Existing melodica keys (divided into black and white keys) independently control the sealing of a single vent. To meet the requirements of a wide range (for melodica development directions of 37-key, 41-key, or more keys), a larger number of reeds are needed. Therefore, a longer body or narrower keys are required. However, the greater distance between the keys on a longer body is not conducive to operation (especially for beginners and students). On the other hand, using narrower keys is not conducive to precise control (it is easy to press two keys at once or accidentally press adjacent keys), thus affecting the sound quality. Summary of the Invention

[0004] The purpose of this invention is to provide a wide-range harmonica. By designing a narrower vent, the overall length of the soundboard can be reduced. Two vents / reeds are controlled by one key, and the switching of the two corresponding reeds is controlled by an adjustment component. This design takes up less space, facilitates control of the harmonica body within a suitable range, and ensures that the key size is large enough for easy use by the user, thereby achieving a wider range of tonal characteristics.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

The soundboard has a connecting part in the middle, an exhaust port on one side of the connecting part, and several non-through ventilation ports arranged side by side on the other side of the connecting part. The connecting part has several through-type oblique openings communicating with the ventilation ports. The reed plate is fixed to the bottom surface of the soundboard and has several tone holes communicating with the exhaust ports. Several reeds opposite to the tone holes are fixed to the bottom surface of the reed plate.

[0007] The lengths of several vents on the soundboard decrease sequentially, and the width and length of the vents are consistent with the width and length of the corresponding sound holes.

[0008] The connecting part is provided with a through-type strip groove;

[0009] The key's baffle is provided with two plugs, and the two plugs respectively cooperate with two adjacent tone holes;

The plate body is provided with a plurality of openings, and the plurality of openings are respectively opposite to a plug on a plurality of piano keys or respectively opposite to another plug on a plurality of piano keys.

[0011] Both ends of the plate are provided with electric actuators, and the piano shell is provided with a mounting part, in which the electric actuators are fixed.

[0012] The electric actuator is electrically connected to a switch, which is located on the periphery of the guitar case. The switch is a push-button switch, a touch switch, or an infrared switch.

The battery is electrically connected to the electric push rod and the switch.

[0015] Furthermore, the top of the piano shell is open and fitted with a cover edge, and the rear side of the piano plate is provided with several protruding edges arranged side by side, the rear side of the protruding edges being in contact with the rear side of the piano shell.

[0016] Furthermore, the bottom of the piano shell is provided with several feet, and the bottom of the piano shell, which is connected to the air intake channel, is provided with an air vent, and the button of the air vent is located on the upper part of the feet.

[0017] Furthermore, both sides of the bottom of the piano shell are provided with arc-shaped portions, and several exhaust grooves are arranged side by side on the arc-shaped portions of the piano shell near the exhaust port.

[0018] Furthermore, a sealing groove is provided on the bottom surface of the piano board and at the position outside several ventilation openings, and a sealing element is provided on the top edge of the air intake channel opposite to the sealing groove.

[0019] Furthermore, a screw hole is provided on the piano plate between two adjacent ventilation openings, and the spring plate is fixed to the piano plate by screws and screw holes.
