Description

Saxophone Mouthpiece

The present invention relates to a saxophone mouthpiece, and in particular to a technical structure improvement of a saxophone mouthpiece.

The mouthpiece of the saxophone is a musical instrument exciter, which produces sound by vibrating the reed fixed on it, and then transmits it to the body of the pipe. The saxophone mouthpiece uses a single reed like the clarinet, but the internal cavity is larger. The length of the mouthpiece, the shape of the internal cavity, the size of the opening and the material will have a significant impact on the timbre. It is known that the mouthpiece of the saxophone includes an opening. When the player holds the mouthpiece, the reed will bend toward the front end of the opening, so when the player blows, the reed will vibrate relative to the window edge. However, most reeds are made of bamboo. When too much saliva is absorbed, the reed will become soft, and the lower lip needs to be used more forcefully to control it in order to produce the correct tone. If too much force is used, the reed will stick too close to the window edge, which will cause the gap between the reed and the window edge to be too small or disappear, making it impossible to vibrate smoothly, resulting in a change in timbre and the inability to play the expected scale smoothly. There are shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and advanced saxophone mouthpiece to solve the above problems.

The main purpose of the invention is to provide a saxophone mouthpiece that can smoothly form a gap between the reed and the edge of the opening window, and has two reed fulcrums with variable positions, so that when the player blows, the reed can vibrate smoothly and produce the ideal timbre and scale.

To achieve the above-mentioned purpose, the present invention provides a saxophone mouthpiece, including a body. The body includes a connecting portion and a mouthpiece portion, the mouthpiece portion defines a front end and a rear end opposite to each other, the rear end is connected to the connecting portion, one side of the mouthpiece portion is provided with an opening for a reed to press against, and the other side is provided with a reflector, and the left and right sides of the opening are provided with two outwardly facing window edges, each of the window edges is arranged in sequence from the front end to the rear end with a first arc convex section, a non-arc convex section and a second arc convex section; wherein the opening is formed between the two window edges, and the two window edges can be pressed against by the reed; wherein the opening corresponds to the reed and at least partially can be covered by the reed.

The following is only an example to illustrate the possible implementation of the present invention, but it is not intended to limit the scope of protection of the present invention, so it should be stated in advance.

Please refer to Figures 1 to 9, which show a preferred embodiment of the present invention. The saxophone mouthpiece of the present invention includes a body 1.

The body 1 includes a connecting portion 2 and a mouthpiece portion 3, wherein the mouthpiece portion 3 defines a front end 31 and a rear end 32 opposite to each other, wherein the rear end 32 is connected to the connecting portion 2, wherein an opening 33 is provided on one side of the mouthpiece portion 3 for a reed 9 to press against, and a reflecting plate 34 is provided on the other side, wherein two window edges 35 facing outward are provided on the left and right sides of the opening 33, wherein each of the window edges 35 is provided with a first arc convex section 351, a non-arc convex section 352 and a second arc convex section 353 arranged in sequence from the front end 31 to the rear end 32; wherein the opening 33 is formed between the two window edges 35, wherein the two window edges 35 can be pressed against by the reed 9; wherein the opening 33 corresponds to the reed 9 and can at least partially be covered by the reed 9. Preferably, the assembly part 2 extends along an axial direction 38, and the inner wall 21 of the assembly part 2 tapers toward the mouthpiece 3 (as shown in Figures 7 and 7A). The inner wall 21 of the assembly part 2 forms an angle θ with the axial direction 38, and the angle θ is between 0.1 and 0.6 degrees. In this embodiment, the angle θ is 0.2 degrees. The assembly part 2 is provided for sleeve connection with a saxophone 8, whereby when the assembly part 2 is sleeved with the gradually expanding saxophone 8, the slightly inclined inner wall 21 is designed to be more tightly sleeved with a cork gasket 81 of the saxophone 8.

When playing, the user holds the reed 9 and the mouthpiece 3 with the front end 31. As a result, since each window edge 35 is sequentially provided with a first arc convex section 351, a non-arc convex section 352 and a second arc convex section 353, when the user holds the reed 9 and the mouthpiece 3, the reed 9 will bend toward the two window edges 35. When the user holds the reed 9 closer to the rear end 32, the reed 9 will abut against the second arc convex section 353. Since the non-arc convex section 352 is a non-arc convex shape, the reed 9 will not flatly abut against the non-arc convex section. 352, so there will be a gap between the reed 9 and the non-arc convex section 352, so that the reed 9 can effectively vibrate to produce low-frequency sound; when the user holds the reed 9 closer to the front end 31, the reed 9 will be attached to the second arc convex section 353 and the reed 9 will be connected to the junction of the first arc convex section 351 and the non-arc convex section 352, and the part of the reed 9 corresponding to the first arc convex section 351 will form high-frequency vibration to effectively produce high-frequency sound, so the present invention can effectively produce the ideal timbre and scale.

Specifically, the mouthpiece 3 is provided with the reflector 34 at the bottom and a top plate 36 at the top. The top plate 36 is provided with the opening 33 near the front end 31, and the top plate 36 is provided for the reed 9 to press against. The mouthpiece 3 also includes two side plates 37, which are connected between the top plate 36 and the reflector 34.

In this embodiment, the saxophone mouthpiece further includes a positioning assembly 4, the two ends of which are respectively assembled to the two side plates 37 and press the reed 9 against the top plate 36 to position the reed 9. Preferably, the positioning assembly 4 includes a U-shaped positioning member 41 and a pressing member 42, the two ends of the positioning member 41 are assembled to the two side plates 37, the pressing member 42 is threaded through the positioning member 41 and presses the reed 9 against the top plate 36, and the tightness of the reed 9 relative to the top plate 36 can be adjusted by screwing the pressing member 42 to perform tuning. One end of the pressing member 42 is provided with a pressing plate 421, and the pressing plate 421 presses against the reed 9. The two side plates 37 are respectively provided with a plurality of locking holes 371, and the positioning assembly 4 is respectively locked in one of the locking holes 371 of the two side plates 37 by two locking pieces 43. The user can selectively lock in one of the locking holes 371 by the two locking pieces 43 to adjust according to the material of different reeds 9.

The extension length of the non-arc convex section 352 is greater than the extension length of the first arc convex section 351, and the extension length of the non-arc convex section 352 is less than the extension length of the second arc convex section 353, so that the length of the reed 9 corresponding to the first arc convex section 351 is shorter for high-frequency vibration.

It should be noted that the non-arc convex section 352 is a plane or a concave surface, and the first arc convex section 351 and the second arc convex section 353 have the same curvature. In this embodiment, the non-arc convex section 352 is a plane. As shown in Figures 8 and 9, in another embodiment of the present invention, the non-arc convex section 352A can be a concave surface, so that the reed 9 can be further prevented from contacting the non-arc convex section 352A. The intersection of the non-arc convex section 352A and the first arc convex section 351 defines a first intersection point A, and the intersection of the non-arc convex section 352A and the second arc convex section 353 defines a second intersection point B. When the player's lips press against the reed When the position of 9 is close to the second intersection B (as shown in FIG8 ), the bending amplitude of the reed 9 is smaller, a first contact end C of the reed 9 is located at the second arc convex section 353 and the reed 9 is not in contact with the second intersection B. The portion of the reed 9 that is not in contact with the mouthpiece 3 is longer and vibrates with the first contact end C as a fulcrum. In this way, the reed 9 has a larger vibration arc and can more easily produce low-frequency sounds. When the player's lips press against the reed 9 near the first intersection A (as shown in FIG. 9 ), the bending amplitude of the reed 9 is larger, and the second contact end D of the reed 9 is located at the second intersection B. The part of the reed 9 that does not contact the mouthpiece 3 is shorter and vibrates with the second contact end D as a fulcrum. In this way, the reed 9 has a smaller vibration arc, and the lower lip does not need to press the reed 9 too hard to produce high-frequency sounds smoothly. Therefore, the present invention has two variable positions of the reed 9 vibration fulcrum to smoothly play the expected scale.

Please continue to refer to Figures 1 to 7. The main body 1 is symmetrically arranged and extends with a center line 11 as the axis. The side of the reflector 34 facing the opening 33 is provided with a plurality of first air guide channels 51 and two second air guide channels 52. The center line 11 divides the reflector 34 into two symmetrical blocks 341. Each of the first air guide channels 51 includes a first guide groove 511 and a second guide groove 512 connected to each other. The extension direction of the first guide grooves 511 is roughly parallel to the direction of the center line 11. The second guide grooves 512 are arranged in a direction parallel to the center line 11. The extension direction of 512 is oblique to the extension path of the first guide grooves 511. The first air guide channels 51 are spaced apart from the center line 11 and symmetrically arranged in the two blocks 341. The plurality of second guide grooves 512 located in the two blocks 341 are obliquely close to the center line 11. The two second air guide channels 52 extend parallel to the center line 11 and are respectively located on the adjacent sides of the center line 11. The two second air guide channels 52 are respectively connected to the second guide grooves 512 located in the two blocks 341.

The first air guide channels 51 are used to guide the air entering from the front end 31 to flow in a specific path. The second guide grooves 512 are inclined toward the center line 11, so that the plurality of first air guide channels 51 have the effect of gathering air. The air gathered through the first air guide channels 51 can flow with more abundant power, so that the player can produce a fuller and mellower tone with less blowing force, so that the player with small lung capacity can control the instrument more easily and quickly.

The two second air-conducting channels 52 are connected to the second guide grooves 512 of the first air-conducting channels 51, so as to achieve the effect of converging and exhausting the gas together, so that the gas is more concentrated and the flow rate is faster. The two second air-conducting channels 52 extend parallel to the center line 11 to ensure that the airflow moves along the direction of the center line 11, so as to achieve the purpose of uniform flow.

Please refer to Figures 9 to 11. In another embodiment of the present invention, the body is symmetrically arranged and extended with a center line 11 as the axis. The reflector 34A is concavely provided with a plurality of third air guide channels 53A on one side facing the opening 33. The reflector 34A is convexly provided with a convex portion 342A near the center line 11 near the rear end. The extension lengths of the third air guide channels 53A are the same. The portion of the third air guide channel 53A near the center line 11 protrudes toward the front end 31, so that the gas near the center line 11 is preferentially guided by the portion of the third air guide channel 53A. The convex portion 342A can guide the gas to flow to the reed to enhance the vibration effect of the reed.
