Description

Technical Field

[0001] This utility model relates to the field of musical instrument technology, and in particular to a melodica with a key protection function. Background Technology

[0002] The melodica, also known as a mouthpiece or harmonica keyboard, is a small, portable keyboard instrument that combines the playing style of keyboard instruments with the sound production principle of free reed instruments. The design of the melodica allows the player to control breath and pitch independently, thus enabling more complex musical expression than the traditional harmonica. It is widely used in various types of music. However, during the carrying and storage of traditional melodica, the keys are easily damaged by external factors, affecting the instrument's lifespan and performance.

[0003] Therefore, a type of melodica with key protection function has been developed to protect the melodica after use, prevent damage to the keys, and ensure the lifespan and performance of the melodica. Utility Model Content

[0004] To overcome the shortcomings of traditional melodica where the keys are easily damaged by external factors during transport and storage, affecting the instrument's lifespan and performance, this utility model provides a melodica with a key protection function that can protect the melodica after use, prevent key damage, and ensure the melodica's lifespan and performance.

[0005] The technical implementation scheme of this utility model is as follows: a melodica with a key protection function includes a melodica, keys, a tailstock, torsion springs, a cover, a front cover lock, and a protective mechanism. The tailstock is connected to the rear side of the melodica, and multiple keys are provided on the upper side of the melodica. The cover is rotatably connected to the tailstock, and two torsion springs are connected between the cover and the tailstock. Front cover locks are connected to the front sides of both the left and right sides of the melodica, and the front cover locks are engaged with the cover. The melodica is provided with a protective mechanism that can protect the keys.

[0006] To further explain, handles are provided on both the tailpiece and the cover, making it easy to carry the melodica.

[0007] To further explain, the protective mechanism includes a double-sided seat, a rotating arm, and a long cover. Both the left and right sides of the melodica are connected to the double-sided seat, and a rotating arm is rotatably connected to each double-sided seat. A long cover is rotatably connected to each rotating arm.

[0008] To further explain, the long cover has a two-layer structure.

[0009] To further explain, it also includes an elastic mechanism, an elastic mechanism fixing seat and an elastic guard plate. Multiple fixing seats are connected to the front side of the cover, and the front sides of the fixing seats are connected by an elastic guard plate.

[0010] To further clarify, the elastic guard plate is curved.

[0011] The beneficial effects of this utility model are as follows: 1. By rotating the long cover on the rotating arm and then rotating the rotating arm on the double-sided seat, the melodica is re-covered above the keys. Then, the cover is locked with the front cover. This achieves the effect of protecting the melodica after use, preventing damage to the keys, and ensuring the service life and performance of the melodica.

[0012] 2. When the melodica is accidentally dropped, the elastic guard plate will contact the ground first, thus cushioning the impact of the melodica falling and preventing it from being damaged. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0020] A melodica with key protection features, such as Figures 1-3As shown, it includes a melodica 1, keys 10, a tailstock 2, torsion springs 3, a cover 4, a front cover lock 5, and a protective mechanism 6. The tailstock 2 is connected to the rear of the melodica 1. Multiple keys 10 are provided on the upper side of the melodica 1. The cover 4 is rotatably connected to the tailstock 2. Two torsion springs 3 are connected between the cover 4 and the tailstock 2. The front cover locks 5 are connected to the front of both the left and right sides of the melodica 1. The front cover locks 5 are engaged with the cover 4. Both the tailstock 2 and the cover 4 are provided with handles for easy carrying of the melodica 1. The protective mechanism 6 is provided on the melodica 1.

[0021] like Figure 1 and Figure 4 As shown, the protective mechanism 6 includes a double-sided base 61, a rotating arm 62, and a long cover 63. The left and right sides of the melodica 1 are connected to the double-sided base 61, and the rotating arm 62 is rotatably connected to the double-sided base 61. The long cover 63 is rotatably connected to the rotating arm 62. The long cover 63 has a two-layer structure, which facilitates the comprehensive protection of the black and white keys of the piano key 10.

[0022] When using this invention, first move the melodica 1 to the playing area using the handle on the tailstock 2. Then, rotate the handle to open the cover 4, causing it to disengage from the front cover lock 5. This causes the torsion spring 3 to deform. Next, connect the mouthpiece to the air inlet on the melodica 1. Play the instrument by pressing the keys 10 while blowing air. After playing, rotate the cover 4 to re-lock it with the front cover lock 5, allowing the cover 4 to cover and protect the melodica 1. When playing the melodica 1 after the cover 4 is open, rotate the swivel arm 62 on the double-sided seat 61. The long cover 63 rotates on the swivel arm 62, so that the long cover 63 rotates to the back of the melodica 1 to avoid affecting the support and playing of the melodica 1. After the melodica 1 is finished playing, the long cover 63 rotates on the swivel arm 62, and then the swivel arm 62 rotates on the double-sided seat 61, so that the melodica 1 covers the keys 10 again. Then the cover 4 is locked with the front cover lock 5. This can protect the melodica 1 after it is finished using, prevent damage to the keys 10, and ensure the service life and playing effect of the melodica 1.

[0023] like Figure 1 and Figure 5 As shown, it also includes an elastic mechanism 7, an elastic mechanism 7 fixing seat 71 and an elastic guard plate 72. Eight fixing seats 71 are connected to the front side of the cover 4. An elastic guard plate is connected between the front sides of the fixing seats 71. The elastic guard plate 72 is arc-shaped to increase the cushioning when landing.

[0024] Using the elastic mechanism 7 of this device, the melodica 1 can be cushioned when it is accidentally dropped. When the cover 4 and the front cover lock 5 are engaged, the fixing base 71 and the elastic guard plate 72 are both located on the front side of the melodica 1. When the melodica 1 is lifted and carried by the handle, the elastic guard plate 72 is located below the melodica 1. When the melodica 1 is accidentally dropped and falls, the elastic guard plate 72 will contact the ground first, so that the elastic guard plate 72 will cushion the impact force when the melodica 1 falls. Thus, it can cushion the melodica 1 when it is accidentally dropped and prevent the melodica 1 from falling and being damaged.
