New description: [New technology field] [0001] This creation is related to saxophone instruments, especially a saxophone mouthpiece. [Prior Art] [0002] Saxophone is a wind instrument, which is mounted on a saxophone body by a mouthpiece 4, wherein as shown in Figs. 5 and 6, the mouthpiece 4 has a through air passage 41 therein. An opening 4 2 is formed at the bottom of the front end of the air duct 41, and a wall surface of the front end of the air duct 41 forms a reflecting surface 43. When the saxophone is played, a reed 4 5 is positioned on the bottom surface of the mouthpiece 4 and covers a portion of the opening 4 2 outside, so that the wall surface of the body of the mouthpiece 4 and the reed 45 are surrounded to form a blow. The air port 44, the mouth of the player, the mouthpiece 4 is blown into the air blowing port 44, and the air spring vibrates the reed 45 to emit sound waves, which are reflected by the internal reflection surface 43 of the mouthpiece 4, and then transmitted. The saxophone body resonates, and the sound of different scales can be produced by the operation of the player. [〇〇〇3] As stated above, the source of the saxophone music is the vibration of the reed 45, and the reflection of the reflecting surface 43 in the mouthpiece 4 is formed, and the loudness of the sound is also related to the sound. The reflection in the mouthpiece 4 is related. The conventional saxophone mouthpiece has a reflective surface 4 3 as a plane. Although there is no big problem in this design, the player always hopes that the energy consumption can be achieved with the same energy consumption, or the same effort. But it can achieve greater loudness, which is the origin of the creation of this creation. [New Content] [〇〇〇4] The main purpose of this creation is to provide a saxophone mouthpiece, Form No. A0101 Page 3 of 14 [0005] M415394 It has the effect of making the sound of the user blow louder. . For the purpose of the foregoing, the present invention provides a saxophone mouthpiece, which includes a body having a through air passage therein, and the two ends of the air duct are respectively a blowing end for blowing air and a plugging The air duct has an opening extending to the bottom of the body at the air blowing end, and the body is provided with a cymbal holder on the bottom surface of the air blowing end, and the cymbal is disposed at the bottom of the air blowing end. a reed seat covering a portion of the opening to form a mouthpiece, and a top surface of the air duct is formed with a reflecting surface at the blowing end, wherein: the reflecting surface is formed outwardly adjacent to the blowing end a first bending section and a second bending section. [Embodiment] [0006] Please refer to FIG. 1 and FIG. 2 , a saxophone mouthpiece provided by the present invention, comprising a body 1 having a through air duct 2 therein, the air duct 2 The two ends are respectively a blowing end 2 1 for blowing in the airflow and a plugging end 2 2 for inserting into the saxophone body. The air duct 2 is opened at the blowing end 21 to extend to the bottom of the body 1. An opening 2 3, the body 1 is provided with a reed seat 14 on the bottom surface of the blowing end 2 1 , the body 1 is slightly tilted upwards at the blowing end 2 1 , and a reed is positioned on the reed a seat 14 is formed to cover a portion of the opening 23 to form a mouthpiece, and a top wall surface of the air duct 2 is formed with a flat reflecting surface 24 at the blowing end 2 1 , and the reflecting surface 24 is adjacent to the blowing air. The end 21 is sequentially polished outward to form a first bending section 2 41 and a second bending section 242 which are increased in inclination with respect to the reflecting surface 24, that is, the slope of the first bending section 241 is greater than the Reflecting surface 2 4, and the form number A0101 4th page / 14 pages M415394 The second bending section 2 4 2 slope is greater than the first bending section 2 4 1, and the A groove 1 2 is disposed on a top surface of the blowing end 2 1 , and a groove 13 is disposed in the groove 1 2 , and the gasket 13 is used to ease the hardness when the nozzle is bitten. sense.

克斯風上，並如第3圖所示，於該吹嘴本體1底部之開 口 2 3外側一部分覆蓋一簧片3，並藉該本體1内部風 道2之壁面與該簧片3共同形成一吹口1 1，吹奏者口 含住該吹口 1 1，並朝該風道2内吹氣，藉著吹入之氣 流以振動該簧片3而發出聲音。簧片3振動所發出之聲 音於物理上為一種能量，並藉空氣分子間之震盪，以縱 波形式傳遞出去，而聲波傳遞至吹嘴内部之風道2，遇 到該風道2頂部之反射面2 4即形成反射現象而朝另一 方向繼續傳遞，如此，聲波經由多次反覆之反射而進入 薩克斯風。 [0008] 而聲波之反射現象所必須遵循之物理法則為能量不 滅定律，若忽略聲波撞擊該反射面24所散失之能量， 則聲波之入射角必須等於反射角，而如第3圖所示，本 創作於該風道2頂部之反射面24靠近該吹氣端2 1所 研磨之第一彎折段2 41及第二彎折段242，乃用以 改變聲波之反射角度，而使聲波與聲波之間所產生之互 相干涉為一相長干涉，即各聲波之間的能量會互相增長 而不是互相抵消，並藉此有助於提高吹嘴所吹出聲音之 響度。 [0009] 再者，如第4圖所示，因該風道2於該吹氣端2 1 表單編號A0101 第5頁/共14頁 M415394 附近所具有之兩個不同斜率之彎折段2 4 1、2 4 2， 與該簧片3共同包圍形成有一具有三段外徑不同之風道 25、26、27，而於吹奏者對該吹口 1 1吹入之氣 流通過該風道25、26、27時，因外徑不同而導致 氣流速度變快，而使該風道2 5、2 6、2 7内之空氣 遇到壁面轉折處產生迂迴之渦流，以生成較佳之共鳴效 果而提高所吹出聲音之響度。 [0010] 惟，以上所述實施例之揭示用以說明本創作，並非 用以限制本創作，故舉凡數值之變更或等效元件之置換 仍應隸屬本創作之範疇。 【圖式簡單說明】 [0011] 第1圖為本創作之立體圖 [0012] 第2圖為本創作之别面圖 [0013] 第3圖為本創作之剖面圖，用以表示聲波於風道内之反 射情形 [0014] 第4圖為本創作之剖面圖，用以表示氣流進入風道内之 流動情形 [0015] 第5圖為習用薩克斯風吹嘴之立體圖 [0016] 第6圖為習用薩克斯風吹嘴之剖面圖 【主要元件符號說明】 [0017] (本創作部份） [0018] 本體 1 吹口 11 表單編號A0101 第6頁/共14頁 M415394As shown in FIG. 3, a portion of the opening 2 3 at the bottom of the mouthpiece body 1 is partially covered with a reed 3, and the wall surface of the inner air duct 2 of the body 1 is formed together with the reed 3 A mouthpiece 1 1, the mouth of the player contains the mouthpiece 1 1, and blows air into the air duct 2, and the sound is blown by the airflow blown to vibrate the reed 3. The sound emitted by the vibration of the reed 3 is physically an energy, and is transmitted in the form of a longitudinal wave by the oscillation between the air molecules, and the sound wave is transmitted to the air duct 2 inside the mouthpiece, and the reflection at the top of the air duct 2 is encountered. The surface 24 forms a reflection phenomenon and continues to transmit in the other direction, so that the sound wave enters the saxophone through a plurality of repeated reflections. [0008] The physical law that must be followed by the reflection phenomenon of sound waves is the law of energy immortality. If the energy lost by the sound wave striking the reflection surface 24 is ignored, the incident angle of the sound wave must be equal to the reflection angle, and as shown in FIG. 3, The reflecting surface 24 at the top of the air duct 2 is adjacent to the first bending section 2 41 and the second bending section 242 which are ground by the blowing end 2 1 to change the reflection angle of the sound wave, so that the sound wave is The mutual interference between the sound waves is a constructive interference, that is, the energy between the sound waves will grow with each other instead of canceling each other, and thereby help to increase the loudness of the sound blown by the mouthpiece. [0009] Furthermore, as shown in FIG. 4, the air passage 2 has two different slopes of the different slopes of the blowing end 2 1 form number A0101 page 5 / 14 pages M415394. 1, 2 4 2, together with the reed 3, a wind tunnel 25, 26, 27 having three outer diameters is formed, and the airflow blown by the player to the air outlet 11 passes through the air passages 25, 26. At 27 o'clock, the airflow speed is increased due to the difference in outer diameter, so that the air in the air passages 25, 26, and 27 encounters a turbulent flow at the wall turning point to generate a better resonance effect and improve the position. Blow out the loudness of the sound. The disclosure of the above-described embodiments is intended to be illustrative of the present invention and is not intended to limit the scope of the present invention.
