Description

Technical Field

[0001] The utility model belongs to the field of alto accordions, and particularly relates to a new type of alto accordion. Background Art

[0002] The accordion is a wind instrument. For a traditional 37-key alto accordion, its range is from f in the sub-contra octave to f3 in the first octave, and for a 32-key soprano accordion, its range is from #f3 in the first octave to c4. It can be seen that for traditional alto and soprano accordions, 25 keys overlap in the same pitch range (as shown in Figure 7 ). The key overlap rate accounts for 67.5% of the traditional alto accordion. At the same time, after counting and analyzing the sheet music of songs in the current existing primary and secondary school "Music" textbooks, it is found that among the ranges of the traditional 37-key accordion, the highest five keys are hardly used in actual use, while the bass keys are lacking, resulting in the problem of unreasonable key settings of the existing traditional 37-key alto accordion. Content of the Utility Model

[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a new type of alto accordion to solve the problem of unreasonable key settings of the existing traditional 37-key alto accordion in the prior art.

[0040] an air inlet passage 31, one end of the air inlet passage 31 communicates with the air storage cavity 22, and the other end of the air inlet passage 31 communicates with the external space. By providing the air inlet passage 31, the air storage cavity 22 can be blown;

[0041] a key sound generating assembly, the key sound generating assembly includes a bass module, a middle module and a treble module. The bass module, the middle module and the treble module are arranged in sequence. The bass module, the middle module and the treble module all include a key 41, a sound generating air flow passage 42, a valve plate 43 and a sound generating reed 44. The key 41 is arranged on the housing 11. The sound generating air flow passage 42 is located in the housing 11 below the key 41. One end of the sound generating air flow passage 42 communicates with the air storage cavity 22, and the other end of the sound generating air flow passage 42 is open. A valve plate 43 is arranged at the opening of the sound generating air flow passage 42. Pressing the key 41 drives the valve plate 43 to open and close the opening of the sound generating air flow passage 42. The sound generating reed 44 is fixedly installed in the sound generating air flow passage 42.

By providing the temporary cavity, part of the saliva can be left in the temporary cavity, reducing the corrosion effect on the sounding reed 44. By connecting the temporary cavity and the air - storage cavity 22 through a connecting pipe, the smooth flow of air can be ensured. At the same time, in order to further ensure that saliva does not flow into the air - storage cavity 22, the intersection position of the connecting pipe and the sealing plate can be set in the middle or upper part of the sealing plate.

[0051] In this embodiment, please refer to Figures 1 to 6 , the key 41 is rotatably installed on the housing 11, and the key 41 is connected to the housing 11 through a spring 45.

[0052] A lug is fixedly installed on the bottom wall of the key 41. The lug is rotatably connected to the housing 11 through a rotating shaft. The rotating shaft is located at the rear of the housing 11. One end of the spring 45 is fixedly connected to the rear end face of the housing 11, and the other end of the spring 45 is fixedly connected to the housing 11. Press the front part of the key 41, so that the rear part of the key 41 rotates upward and stretches the spring 45. Release the key 41, and the spring 45 will drive the key 41 to reset.

[0053] In this embodiment, please refer toFigures 1 to 6 Above the air storage cavity 22, a hollow pipe 51 is fixedly installed. One end of the hollow pipe 51 is sealed, and the other end is open. A number of partition plates 52 are fixedly installed in the hollow pipe 51, and the number of partition plates 52 divides the inside of the hollow pipe 51 into a number of sound - generating air flow channels 42;

[0054] A through - hole 53 is formed in the inner bottom wall of the hollow pipe 51, and the through - hole 53 communicates the sound - generating air flow channel 42 with the air storage cavity 22.

[0055] The sound - generating reed 44 is fixedly installed at the through - hole 53.

[0056] The valve plate 43 is located at one end of the sound - generating air flow channel 42 away from the through - hole 53. The valve plate 43 is fixedly connected to the key 41, and the rotation of the key 41 drives the valve plate 43 to open and close the sound - generating air flow channel 42.

[0057] Press the front part of the key 41 to make the rear part of the key 41 rotate upward, thereby driving the valve plate 43 to rotate, so that the valve plate 43 disengages from the sound - generating air flow channel 42. At this time, the sound - generating air flow channel 42 is opened, and the air flows through the air storage cavity 22, the through - hole 53, and the sound - generating air flow channel 42 to the outside. At this time, due to the passage of the air, the sound - generating reed 44 will be driven to generate sound.

[0058] In this embodiment, please refer to Figures 1 to 6 A handle 61 is fixedly installed on the bottom wall of the housing 11.

[0059] By providing the handle 61, it is convenient for the performer to hold.

[0060] The above - mentioned embodiments only illustratively explain the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above - mentioned embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
