[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] See appendix Figure 1 -Appendix Figure 7 A mouthpiece includes a connecting tube 1, an air tube 2, and a mouthpiece opening 3. The air tube 2 has a cavity 20 inside, which passes through the connecting tube 1 and connects to the mouthpiece opening 3. The bottom surface inside the mouthpiece opening 3 has a guide slope 30 that is inclined towards the cavity 20. The inner wall of the cavity 20 has a spiral groove 200 that extends along the length of the cavity 20, and the air inlet 201 at the front end of the spiral groove 200 is set corresponding to the guide slope 30.
[0037] Specifically, when blowing air into the mouthpiece bore 3 of the flute head, part of the airflow flows along the guide slope 30 into the spiral groove 200 and is guided by the spiral groove 200 to the lumen 20 to avoid the airflow entering the interior of the flute head from crossing and confusing, thereby making the sound emitted round and full, powerful, and improving the overall timbre effect; and compared with the existing flute head, the design of the flute head can fully utilize the airflow, facilitate the player to control the strength, and reduce the requirement for playing experience.
[0038] Referring to the accompanying drawings Figure 1 - the accompanying drawings Figure 7 The upper surface of the guide slope 30 is symmetrically provided with guide grooves 301 on the left and right sides, the guide grooves 301 extend from the inlet end of the mouthpiece bore 3 to the lumen 20, and both guide grooves 301 are connected to the air inlet 201.
[0039] Specifically, when blowing air into the mouthpiece bore 3 of the flute head, part of the airflow contacts the guide slope 30 and is then divided into two guide grooves 301, so as to guide the airflow to pass through the air inlet 201 and enter the spiral groove 200 uniformly, and the cooperation of the guide grooves 301 and the spiral groove 200 can improve the timbre, and has the advantages of simple structure and slightly reducing the weight of the flute head.
[0040] Referring to the accompanying drawings Figure 1 - the accompanying drawings Figure 7 The upper surface of the guide slope 30 is symmetrically provided with guide grooves 301 on the left and right sides, the guide grooves 301 extend from the inlet end of the mouthpiece bore 3 to the lumen 20, and both guide grooves 301 are connected to the air inlet 201.
[0041] Referring to the accompanying drawings Figure 1 - the accompanying drawings Figure 7 The guide slope 30 is provided with a gas distribution block 303 at the connection between the guide groove 301 and the air inlet 201; when the guide groove 301 guides the airflow to the gas distribution block 303, the gas distribution block 303 can diffuse the airflow, so that the airflow can enter the spiral groove 200 more uniformly.
[0042] Referring to the accompanying drawings Figure 1 - the accompanying drawings Figure 10 According to different flute head models, the ratio of the depth of the lumen 20 to the depth of the spiral groove 200 changes, if the depth of the lumen 20 is h1, the depth of the spiral groove 200 is h2, and h1 / h2=z, 2.5≤z1≤4.
[0043] Further, according to different flute head models, the ratio of the inner diameter of the lumen 20 to the inner diameter of the spiral groove 200 changes, if the inner diameter of the lumen 20 is d1, the inner diameter of the spiral groove 200 is d2, then d1 / d2=z2, 1.2≤z2≤1.3.
[0044] For ease of understanding, we will use alto and tenor mouthpieces as examples here, as shown in the attached diagram. Figure 1 -Appendix Figure 7 If the mouthpiece is a mid-range mouthpiece, then h1=64mm, h2=25mm, z1=2.56; d1=16.25, d2=13, z2=1.25; see attached. Figure 8 -Appendix Figure 10 If the mouthpiece is a tenor mouthpiece, then h1=74mm, h2=20mm, z1=3.7; d1=17.01, d2=13.5, z2=1.26.
[0045] It should be noted that the above example is only one embodiment. The actual values of z1 and z2 can be adjusted according to the desired timbre.
[0046] See appendix Figure 1 -Appendix Figure 10 In actual production, the spiral groove 200 can be used alone as described in the above embodiment, or it can be used in conjunction with the guide groove 301. Similarly, the guide groove 301 can also be used alone. For ease of understanding, in this embodiment, the spiral groove 200 is not provided on the inner wall of the cavity 20, and the guide grooves 301 are symmetrically provided on the left and right sides of the upper surface of the guide slope 30. The guide grooves 301 extend from the inlet end of the mouthpiece 3 towards the air pipe 2, and both guide grooves 301 are connected to the cavity 20.
[0047] Specifically, when air is blown into the mouthpiece 3 of the mouthpiece, part of the airflow is diverted to the guide grooves 30 on both sides after contacting the guide slope 30. The guide grooves 301 guide the airflow to enter the cavity 20 evenly, which changes the existing uniform distribution of airflow in the mouthpiece during the process of entering the air tube 2, reduces the possibility of airflow crossing and disorder, and makes the tone more beautiful.
[0048] See appendix Figure 1 -Appendix Figure 2 The outer wall of the connecting tube 1 has a circular array of multiple sound guide holes 10; when the airflow passes through the connecting tube 1, the multiple sound guide holes 10 can send vibrations synchronously to facilitate sound transmission and improve the response speed.
[0049] See appendix Figure 1 -Appendix Figure 10 The inner diameter of the sound guide hole 10 is d3, where d3 = 2.1 mm. This design ensures optimal vibration response.
[0050] See appendix Figure 11 A saxophone includes a mouthpiece, a connecting tube 1 detachably connected to the neck 4 of the saxophone, and a saxophone equipped with this mouthpiece also has the aforementioned advantages.
[0051] It should also be noted that, while the embodiments of the application have been shown and described, it is to be understood that for the purposes of the present application, non-substantial changes and modifications can be made by one ordinarily skilled in the art to the aforementioned embodiments and details without departing from the spirit and scope of the present application.
