Description

Technical Field

[0001] The present application relates to the technical field of music teaching aids, and in particular to a music teaching aid that can be loaded and unloaded and is a dual-purpose sound block and sound box. Background Art

[0002] The most common musical instrument is the xylophone, which was created as early as the Neolithic Age. The original xylophone was rough, with wooden sticks cut into different lengths. The discovery of different pitches was a leap forward, creating conditions for future generations to understand the scale. Now it can be made of various materials, collectively referred to as "sound bar instruments."

[0003] There are two main styles of sound bar instruments:

[0004] One is the block series, where each piece is equipped with a resonance box (or resonance tube), and the frequency of the piece is exactly the same as the natural frequency of the air in the resonance box, which belongs to "coupling resonance" in acoustics. The tone is bright. The other is the box series, which consists of 13 to 15 pieces, which resonate in groups by the 4 sub-boxes in the resonator box, which belongs to "uncoupled resonance". It is reformed on the basis of the boat-shaped single-box xylophone (more than 20 pieces) in Indonesia and Thailand in Southeast Asia. Compared with the "box" xylophone, the "block" xylophone makes full use of the air vibration energy in the box (tube) for "coupled resonance", and the sound quality is better than the latter. It is mostly used for primary school and young children. One person holds a piece in his hand to induce the students' concept of "pitch"; the latter enlightens the students' concept of "scale".

[0005] The existing, traditional "toy steel piano" has two "node" holes on the piano pieces, which are cumbersome to make and difficult to tune accurately, but they are flooding the toy market. A piano piece with only 8 notes needs to have 16 "node" holes. A "steel piano" with a wide range of sound must have dozens of "node" holes, and the support process is cumbersome. If the material density is slightly poor, the node must be moved to a precise position, otherwise it will affect the pitch, which is not conducive to the pitch hearing of early childhood children; while the improved German box-type xylophone piece has only one node hole, and the other node has no hole, the process is halved, and the inside of the piano box is divided into 4 sub-boxes, each of which has 3 to 4 groups of piano pieces, with a range of one and a half octaves to two octaves. The frequency of the lowest piano piece in each group is the same as the natural vibration frequency of the air cavity in the sub-box, and the other piano pieces in the group resonate with the sub-box by frequency division, but during installation, it still needs to be installed through the cooperation of rubber plugs and node holes, and disassembly and assembly are more cumbersome.

[0006] In view of the above-mentioned prior art, the inventor believes that there is an urgent need for a detachable music teaching aid with a sound block and a sound box as both a dual-purpose teaching aid and adjustable nodes for easy disassembly and assembly while improving the pitch of the teaching aid. Summary of the invention

[0007] In order to improve the pitch accuracy of music teaching aids while facilitating the disassembly and assembly of the teaching aids and the adjustment of nodes, the present application provides a dual-purpose detachable music teaching aid combining a sound block and a speaker.

[0008] The dual-purpose detachable music teaching aid combining a sound block and a speaker provided by the present application adopts the following technical solutions:

[0009] A dual-purpose detachable music teaching aid combining a sound block and a speaker includes a resonance tube, a sound piece, and a plurality of fixing components for detachably arranging the sound piece on the resonance tube;

[0010] The fixing component includes a soft knot wire sleeve sleeved on the outer wall of the sound piece, and a hard knot wire clip for detachably fixing the sound piece sleeved with the soft knot wire sleeve on the outer wall of the resonance tube;

[0011] Both opposite ends of the resonance tube are open, one open end of the resonance tube is beveled, and a sealing plug is arranged at the other open end of the resonance tube.

[0012] Optionally, the hard knot wire clip is integrally in an "n" shape, the resonance tube is located on one side of the opening of the hard knot wire clip, and hook parts are symmetrically arranged on one side of the hard knot wire clip where the resonance tube is located. A foot hook edge for engaging with the hook part is arranged on the side wall of the resonance tube facing away from the sound piece.

[0013] Optionally, an embedding groove for embedding the soft knot wire sleeve is opened on the inner wall of the top of the hard knot wire clip facing the soft knot wire sleeve.

[0014] Optionally, the length direction of the foot hook edge is the direction of the openings at both ends of the resonance tube.

[0015] Optionally, deformation grooves are opened at the inner wall corners of both sides of the "n" - shaped hard knot wire clip close to the soft knot wire sleeve.

[0016] Optionally, under the condition that the thickness and width of the sound piece are equal, according to the equal temperament length, the adjacent length ratios of the semitones from long to short are all The connecting lines of their length endpoints are parabolic.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. When the present invention is used, a corresponding number of soft node wire sleeves are fixedly mounted on the outer wall of the corresponding nodes of the sound piece according to the requirements of the scale and the vibration mode of the required sound piece, and then the sound piece is detachably fixed to the resonance tube body by a hard node wire clamp. When used, one end of the resonance tube opening is sealed by a sealing plug, so that only the resonance tube is arranged in an inclined surface and one side of the opening is connected to the outside to form a sound outlet. The inclined sound outlet minimizes the adverse reflection of the inner wall of the resonance tube to the sound waves, and can significantly reduce the standing waves in the tube, thereby facilitating the disassembly and assembly of the teaching aids and the adjustment of the nodes while improving the pitch of the music teaching aids.

[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme of the embodiment of the present application will be clearly and completely described in conjunction with the drawings of the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0024] Unless otherwise defined, the technical terms or scientific terms used herein shall have the common meanings understood by persons with ordinary skills in the field to which this application belongs. The words "one" or "an" and the like used in the patent application specification and claims of this application do not indicate a quantity limitation, but indicate the existence of at least one.

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] The embodiment of the present application discloses a dual-purpose music teaching aid of a sound block and a sound box that can be loaded and unloaded.

[0027] Reference Figure 1 and Figure 2 A dual-purpose music teaching aid of a sound block and a speaker that can be loaded and unloaded, comprising a sound piece 1, a resonance tube 2 and a fixing assembly 3, wherein the fixing assembly 3 is provided with a plurality of pieces. In this embodiment, the resonance tube 2 is a rectangular tube body with openings at both ends, and the number of the fixing assembly 3 is preferably two groups. The material of the sound piece 1 is vinyl resin, and the proportion of glass fiber squeezed into the adjustment is 1.6ρ(g / cm 3 ) presents the best timbre, the sound piece 1 is detachably fixed on the outer wall of the resonance tube 2 through the fixing component 3, forming a sound block type glockenspiel with excellent timbre.

[0028] Reference Figure 1 and Figure 2 The opening at one end of the resonance tube 2 is arranged with an inclined surface, and a sealing plug 4 is inserted and fixed at the opening at the other end of the resonance tube 2. In this embodiment, the sealing plug 4 is a rubber sealing plug 4. When in use, one end of the resonance tube 2 is sealed by the sealing plug 4, and the end of the resonance tube 2 arranged with the inclined surface forms a sound outlet. When the sound piece 1 is struck, the sound wave is transmitted from the end of the resonance tube 2 arranged with the inclined surface. The inclined surface setting minimizes the adverse reflection of the inner wall of the resonance tube 2 to the sound wave as much as possible, and can significantly reduce the standing wave in the tube, thereby playing an effect of improving the timbre.

[0029] Reference Figure 2 and Figure 3 The fixing component 3 includes a soft node wire sleeve 31 and a hard node wire clamp 32. The soft node wire sleeve 31 is fixedly mounted on the outer wall of the sound piece 1 as a node of the sound piece 1. The hard node wire clamp 32 is used to clamp and fix the sound piece 1 with the soft node wire sleeve 31 on the outer wall of the resonance tube 2, thereby realizing the relative fixation of the sound piece 1 and the resonance tube 2. When in use, the sound piece 1 is struck, and the sound piece 1 forms a rod vibration with both ends fixed under the positioning of the two sets of fixing components 3. At this time, the sound piece 1 and the resonance tube 2 undergo "coupled resonance" to obtain the timbre of the scale and pitch required for music performance.

[0030] When in use, the position of the soft node line sleeve 31 can be freely selected and adjusted according to the required scale and pitch, thereby forming two "wave nodes" of the sound piece 1, which not only saves the "node" opening, but also saves the sponge strip and adhesive. The node line sleeve can be moved to the optimal position (wave node) to obtain the best timbre. Even if there is an error in the material density of the sound piece 1, the position of the "node line sleeve" can be moved to adjust the wave node. When it is necessary to perform multiple scales and pitches together, it is only necessary to prepare multiple teaching aids and arrange them in sequence, and adjust the soft node line sleeve 31 to the appropriate position, so that a speaker-type carillon with good timbre and high pitch can be quickly assembled, which improves the practicality and convenience of the music teaching aid.

[0031] According to the relationship between pitch and frequency, the twelve semitones of the equal temperament are in sequence: c-#c-d-#d-e-f-#f-g-#g-a-#a-b-c1, and the frequency ratios of adjacent tones in ascending pitch order are all When the whole reed of this application has equal thickness and width, according to the equal temperament length, the adjacent length ratios of the semitones from long to short are all The connecting line of their length endpoints is a parabola. This is a unique discovery of this patent and can bring great convenience in the production process.

[0032] Refer to Figure 2 and Figure 3 , the hard node line clip 32 is integrally in an "n" shape. The resonance tube 2 is located on one side of the opening of the hard node line clip 32. Hook parts 5 are symmetrically arranged on one side wall of the hard node line clip 32 where the resonance tube 2 is located. In this embodiment, the hook parts 5 are integrally formed with the hard node line clip 32. A foot hook edge 6 that is engaged with the hook parts 5 is integrally formed on the side wall of the resonance tube 2 facing away from the reed 1. During installation, the reed 1 sleeved with the soft node line sleeve 31 is correspondingly placed on the outer tube wall of the resonance tube 2. Subsequently, the hard node line clip 32 is used to sleeve and clamp the reed 1 sleeved with the soft node line sleeve 31 and the resonance tube 2, and the hook parts 5 on the hard node line clip 32 are engaged and hooked with the foot hook edge 6 on the bottom side wall of the resonance tube 2, so as to realize the relative fixation of the reed 1 and the resonance tube 2.

[0033] Refer to Figure 2 and Figure 3 , the length direction of the foot hook edge 6 is the direction of the two ends of the resonance tube 2 opening. Furthermore, the hooking and fixation of the hard node line clip 32 at any position on the resonance tube 2 are realized, so as to realize the position adjustment of the soft node line sleeve 31 to achieve the purpose of adjusting the scale, and improve the practicability and adaptability of the music teaching aid.

[0034] Refer to Figure 1 and Figure 2 , an embedding groove 7 for embedding the soft node line sleeve 31 is opened on the top inner wall of the hard node line clip 32 facing the soft node line sleeve 31. When the hard node line clip 32 is used to clamp and fix the reed 1 sleeved with the soft node line sleeve 31 and the resonance tube 2, the soft node line sleeve 31 is embedded into the embedding groove 7 on the hard node line clip 32, further reducing the possibility of relative displacement between the soft node line sleeve 31 and the reed 1 during use, as well as the possibility of relative displacement between the hard node line clip 32 and the soft node line sleeve 31 during use, thereby reducing the possibility of poor tone quality and inaccurate scale caused by the insecure fixation of the fixing component 3.

[0035] Refer to Figure 3, on both inner wall corners of the "冂"-shaped rigid node clip 32 close to the flexible node sleeve 31, deformation grooves 8 are provided. The length direction of the deformation grooves 8 is the same as the length direction of the resonance tube 2. During installation, in order to tightly clamp and fix the sounding piece 1 and the resonance tube 2 to prevent the sounding piece 1 from vibrating and shifting during the knocking process, the inner wall width of the rigid node clip 32 usually needs to be slightly smaller than the maximum width of the resonance tube 2. When clamping, the "冂"-shaped rigid node clip 32 can undergo slight deformation under the pushing of the outer wall of the resonance tube 2, thereby increasing the clamping force to achieve tight fixation. The two inner wall corners of the rigid node clip 32 close to the flexible node sleeve 31 are the main action points of the deformation, so they are more likely to be damaged. Through the deformation grooves 8, the force generated at the corners during the deformation of the rigid node clip 32 can be dispersed, thereby reducing the possibility of damage or destructive deformation occurring at the two inner wall corners of the rigid node clip 32 during long-term use and improving the service life of the rigid node clip 32.

[0036] The implementation principle of a sound block and speaker dual-purpose detachable music teaching aid in an embodiment of the present application is as follows: During use, according to the scale requirements and the vibration mode of the required sounding piece 1, the corresponding number of flexible node sleeves 31 are fixedly sleeved on the outer walls of the corresponding nodes of the sounding piece 1, and then the sounding piece 1 sleeved with the flexible node sleeve 31 is clamped and fixed on the tube body of the resonance tube 2 through the rigid node clip 32. The groove 7 and the hook portion 5 provided on the rigid node clip 32 greatly improve the firmness of the fixation of the sounding piece 1 and the resonance tube 2 through the fixing component 3, thereby improving the accuracy of the scale during the use of the music teaching aid;

[0037] At the same time, one end of the opening of the resonance tube 2 is blocked by the sealing plug 4, and only the resonance tube 2 is arranged in an inclined plane and the opening side communicates with the outside to form a sound outlet. During application, when the sounding piece 1 is knocked, the sound piece and the resonance tube 2 generate "coupled resonance". The inclined sound outlet reduces as much as possible the adverse reflection of the sound wave by the inner wall of the resonance tube 2 and can significantly reduce the standing wave in the tube. And when the whole sounding piece 1 has equal thickness and width, according to the equal temperament length, the adjacent length ratio of the semitones from long to short is The connecting line of their length endpoints is a parabola, which is the nearest timbre curve, thereby facilitating the disassembly and assembly of the teaching aid and the adjustment of the nodes while improving the pitch accuracy of the music teaching aid.

[0038] When multi-scale and pitch joint performances are required, only multiple teaching aids need to be prepared and arranged in sequence, and the flexible node sleeve 31 is adjusted to an appropriate position, and a speaker-type glockenspiel with good timbre and high pitch accuracy can be quickly assembled, realizing dual use and improving the practicality of the music teaching aid.

[0039] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
