Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to a toy recorder capable of self-adjusting pitch. Background Art

[0002] Toy recorders are toys that simulate real recorders and are designed for children. They are intended for children to entertain and learn the playing techniques of real recorders during play, thereby helping children develop an interest in music, perception of pitch, finger coordination and creativity, guiding children to get in touch with music in a relaxed and pleasant atmosphere, and laying the foundation for further learning of real instruments.

[0003] A toy recorder is usually a long tubular structure with a blowing hole formed at one end and multiple finger holes on its surface. In addition to its appearance being close to that of a real recorder, the sound-generating principle of the toy recorder is also based on the same airflow resonance as that of a real recorder. When a child puts his lips close to the blowing hole and blows, an air column is formed when the exhaled air flows through the blowing hole. The length of the hollow column determines the change in pitch. The length of the air column changes when the child blocks or opens different numbers of finger holes, thereby producing different pitches. Children can play a variety of musical elements through different combinations of finger holes. In addition to the influence of the length of the air column, the pitch is also determined by the velocity and angle of the airflow when the child blows. Generally, the faster the velocity of the airflow, the higher the frequency and the larger the amplitude, and vice versa. For example, the pitch of the toy recorder recorded in the Chinese patent with announcement number CN204261326U and patent name "Children's DIY Dragon Flute Toy" when a child plays it is determined by changing the number of finger holes blocked or opened, the blowing velocity, and the blowing angle.

[0004] Therefore, the pitch of the toy recorder is completely determined by the playing method of the child as the player. The toy recorder itself cannot change the pitch when the playing method is fixed, which will inevitably lead to low fun in playing the toy recorder. Moreover, for children who have not yet fully mastered the playing skills, the pitch played by the toy recorder may not make them feel comfortable. Therefore, it is urgent to invent a new toy recorder that can solve the above problems. Utility Model Content

[0005] In view of the above situation, in order to overcome the problem that the pitch of the existing toy recorder cannot be changed when the playing method is fixed, resulting in low fun in playing, and for children who have not yet fully mastered the playing skills, the pitch played is likely to not make them feel comfortable, the purpose of the utility model is to provide a toy recorder with self-adjustable playing pitch, which is more interesting and children can adjust the pitch to a comfortable range according to their own needs.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A toy vertical flute capable of self-adjusting pitch comprises a flute head and a flute body, and also comprises a tuning component, wherein the tuning component comprises a limit window frame and at least one tuning foot, wherein the limit window frame is detachably arranged in a flute window of the flute head, the tuning component is formed on the inner wall of the limit window frame and extends to a sound outlet hole in the flute window, and the tuning foot passes through an airway and is horizontally arranged on a side of a blowing hole close to the sound outlet hole, thereby partially blocking the blowing hole.

[0008] Preferably, a clamping portion is formed on the side wall of the tuning foot, and the clamping portion abuts against the inner wall of the airway on the peripheral side below the sound outlet.

[0009] Preferably, there are two tuning pins, which are spaced apart and disposed transversely at two ends of a side of the blowing hole close to the sound outlet.

[0010] Preferably, the total width of the tuning feet is smaller than the width of the airway.

[0011] Preferably, a step position is formed at the bottom of the position-limiting window frame, and the step position cooperates with the edge step of the flute window.

[0012] Preferably, a plurality of anti-slip grooves are formed on the top wall of the position-limiting window frame.

[0013] Preferably, the corners of the limiting window frame and the surface of the tuning foot are rounded.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] When the toy recorder of the utility model is played by children, when the children put their lips close to the blowing hole of the flute head and blow air, the airflow passes through the airway at the intersection of the blowing hole and the sound outlet hole, and according to the law of conservation of flow, the airflow velocity increases. At this time, the vibration frequency and amplitude of the air column formed by the airflow increase, thereby increasing the pitch, and then the pitch can be changed through its own structure, which provides stronger fun for children when playing, and ensures that the children can adjust the pitch of the blowing without changing their own blowing method, so that the pitch is kept in a range that makes them feel comfortable.

[0025] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed and specific directions, structures, and operations, and therefore should not be understood as limitations on the present utility model.

[0027] like Figures 1 to 7As shown, the utility model relates to a toy clarinet with self-adjustable pitch, which includes a mouthpiece 1 and a body 2. This is a conventional arrangement of existing toy clarinet, and is not the focus of the utility model. For ease of understanding, the structures of the mouthpiece 1 and the body 2 are briefly described herein. The mouthpiece 1 is connected to one end of the body 2, and the insides of the mouthpiece 1 and the body 2 are connected to form an airway. The opening at the other end of the mouthpiece 1 is a blowing hole 101, and a mouthpiece window 102 is provided on its side wall, and a sound outlet hole 103 is provided in the mouthpiece window 102. One side of the sound outlet hole 103 is a lip piece 104, and the lip piece 104 is inclined upward from one end thereof close to the sound outlet hole 103 to the other end. The width of the lip piece 104 on one side close to the sound outlet 103 gradually decreases to form a tapered side edge structure. A plurality of finger holes 201 are provided on the flute body 2 along the length direction. The other end of the flute body 2 is a trumpet-shaped pipe mouth 202. In addition to the above-mentioned flute head 1 and flute body 2, the toy clarinet of the utility model also includes a tuning component 3. The tuning component 3 is composed of a limiting window frame 301 and at least one tuning foot 302. The tuning component 3 is detachably arranged in the flute window 102 of the flute head 1 through the limiting window frame 301. It can be understood that the limiting window frame 301 is a frame-shaped structure, thereby avoiding obstruction to the sound outlet 103 and the lip piece 104. The tuning structure The tuning member 3 is formed on the inner wall of the limiting window frame 301, and each tuning member 3 extends to the sound outlet hole 103 in the flute window 102, and each tuning foot 302 passes through the airway and is horizontally placed on the side of the blowing hole 101 close to the sound outlet hole 103. Under the action of the tuning foot 302, the blowing hole 101 is partially blocked, and the inner diameter of the airway at the intersection of the blowing hole 101 and the sound outlet hole 103 is reduced. When the child puts the lips close to the blowing hole 101 of the flute head 1 and blows air, the airflow passes through the airway at the intersection of the blowing hole 101 and the sound outlet hole 103. According to the law of conservation of flow, the airflow velocity increases. At this time, the vibration frequency and amplitude of the air column formed by the airflow increase, thereby To increase the pitch, it should also be mentioned that the tuning member 3 forms different models according to the number of tuning feet 302 or the width of the tuning feet 302. When the selected tuning member 3 has more tuning feet 302 or the width of the tuning feet 302 is larger, the inner diameter of the airway at the intersection of the blowing hole 101 and the sound outlet hole 103 is further reduced, and the pitch increases accordingly, otherwise the pitch decreases. The pitch can be changed through its own structure, which provides stronger fun for children when playing, and ensures that children can adjust the pitch of their blowing without changing their own blowing method, so that the pitch remains within a range that makes them feel comfortable.

[0028] like Figure 3 , Figure 4 and Figure 7As shown, a clamping portion 302a is formed on the side wall of the tuning foot 302. From the overall point of view, the clamping portion 302a is a protruding structure from the side wall of the tuning foot 302, so that the shape formed between it and the tuning foot 302 is L-shaped. The clamping portion 302a abuts against the inner wall of the airway on the lower side of the sound outlet hole 103, and then forms a buckle connection with the mouthpiece 1, which effectively prevents the tuning member 3 from moving up. At the same time, it cooperates with the tuning foot 302 embedded in the sound outlet hole 103 to limit the horizontal movement and deflection of the tuning member 3. In addition, the downward movement of the tuning member 3 can also be limited by the limiting window frame 301, so that the tuning member 3 is firmly maintained in the flute window 102 of the mouthpiece 1 after installation.

[0029] like Figure 3 , Figure 4 and Figure 7 As shown, there are two tuning feet 302, which are spaced apart and horizontally placed at the two ends of one side of the blowing hole 101 close to the sound outlet hole 103. The clamping portion 302a formed on each tuning foot 302 abuts against the inner wall of the airway on the lower side of the sound outlet hole 103 to form a buckle connection, and then the tuning member 3 and the mouthpiece 1 are balanced by increasing the positioning points between the tuning member 3 and the mouthpiece 1 through two-point positioning, and correspondingly, the stability of the fixing of the tuning member 3 and the mouthpiece 1 is further improved.

[0030] Furthermore, the total width of each tuning foot 302 is smaller than the width of the airway. Based on the above arrangement, the tuning foot 302 of the tuning component 3 is inserted into the sound outlet to avoid blocking the airway at the intersection of the blowing hole 101 and the sound outlet 103, thereby ensuring that the airflow can pass through the airway normally when the child plays.

[0031] like Figure 4 and Figure 7 As shown, a step position 301a is formed at the bottom of the limiting window frame 301, and the step position 301a cooperates with the edge step of the flute window 102 to form an integral fit, thereby ensuring the stability of the position between the tuning component 3 and the flute head 1, and preventing the tuning component 3 from tilting and misaligning, thereby achieving precise fit between it and the flute head 1.

[0032] like Figures 1 to 3 As shown, a plurality of anti-skid patterns 301b are formed on the top wall of the limiting window frame 301. The anti-skid patterns 301b play an anti-skid role when children disassemble and assemble the tuning component 3 by hand, thereby reducing the difficulty of disassembling and assembling the tuning component 3 and making it easier to install.

[0033] Furthermore, the corners on the surfaces of the limiting window frame 301 and the tuning foot 302 are rounded. The rounded corners can prevent children from getting scratched by the corners when they use their hands to disassemble and assemble the tuning component 3, thereby protecting the safety of the children. At the same time, it can also reduce damage to the original sharp corners, protect the overall structure of the tuning component 3, and extend its service life.

[0034] Combination Figures 1 to 7 When children play with the toy recorder of the present invention, if they want to change the pitch, in addition to the conventional method, that is, the number of finger holes 201 blocked or opened on the flute body 2 can be controlled by the children's fingers to change the pitch, they can also select a tuning member 3 of a suitable type, buckle the step surface of the limiting window frame 301 of the tuning member 3 to the flute window 102 of the mouthpiece 1, and ensure that the tuning foot 302 is embedded in the sound hole 103. At the same time, the clamping part 302a on the tuning foot 302 is abutted against the inner wall of the airway on the lower side of the sound hole 103 to form a buckle connection to fix the tuning member 3. At this time, if the child puts the lips close to the blowing hole 101 of the mouthpiece 1 to blow air, the airflow will increase when the airflow passes through the airway at the intersection of the blowing hole 101 and the sound hole 103, and the vibration frequency and amplitude of the air column formed by the airflow will increase, thereby achieving an increase in the pitch.

[0035] The above embodiments and descriptions are only for explaining the principle and the best embodiment of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
