Description

[0001] This application is a divisional application of the original invention, entitled "A rhythmic dynamic device for music learning". The application date of the original application is July 21, 2022, and the application number is 202210858719.3. Technical Field

[0002] The invention relates to the technical field of music learning, in particular to a rhythm dynamic device for music learning. Background Art

[0003] Music is an art form that uses auditory images composed of organized sounds to express people's thoughts, feelings and social reality. It is also one of the art forms that can most instantly touch people. When the melody sounds, people are often irresistibly immersed in the musical atmosphere, which makes people forget their troubles and purifies their souls. Any art form has its own way of expressing ideas and shaping artistic images. For example, dance is through body movements and facial expressions, painting is through lines, colors, and composition, and literature is through words, phrases, sentences, and articles to embody artistic images. Usually, people distinguish different types of art by different means of expression, such as different musical instruments. Music can also express the intentions of musicians and music composers. Music is an art form that uses sound as a means of expression. The shaping of images is completed with organized sounds as materials. Therefore, just as literature is the art of language, music is the art of sound. This is one of the basic characteristics of musical art. Sound, as a means of expression of musical art, has some characteristics that are different from other sounds in nature.

[0022] Compared with the prior art, the beneficial technical effects of the present invention are:

[0023] (1) A rhythm conversion observation mechanism is provided, and the audio played is analyzed and detected by an audio analysis detector, so that the rhythm of the music played can be obtained in time, and the change of the rhythm is converted into an electrical signal, which is transmitted to the electric telescopic rod, so that the electric telescopic rod can extend and shorten with the rhythm of the music, and the electric telescopic rod drives the trapezoidal push block to move forward and backward in accordance with the rhythm of the music played. When the trapezoidal push block moves, it squeezes the trapezoidal fitting block, so that the trapezoidal fitting block and the lifting block can move up and down together, and the frequency and amplitude of the lifting correspond to the frequency and amplitude of the electric telescopic rod pushing the trapezoidal push block, that is, the amplitude and frequency of the lifting of the lifting block can match the rhythm of the music played. When learning music, the change of rhythm can be intuitively seen through the lifting and lowering activities of the lifting block, and the high and low notes of the music can be clearly expressed, which provides great convenience for users to learn music. While listening to the rhythm of the music, the lifting and lowering activities of the lifting block can be compared and learned, which improves the learning efficiency, provides a variety of ways for beginners to master the rhythm of music, and reduces the difficulty of learning.

[0024] (2) The mounting frame and the mounting plate cooperate with each other so that the top cover is installed on the top of the fixed box and fits tightly with the sealing gasket. There is also a sound insulation pad inside the fixed box, which plays a role of sealing and sound insulation when playing music, so that the music will not spread outward, avoiding the music sound being too loud to affect other people around. The audio analysis detector and the audio player are both located inside the fixed box. While soundproofing, the sound collected by the audio analysis detector comes from the played music and will not be affected by the noise of the external environment, preventing the noisy environment from causing errors in the collected sound and causing errors in the learning music rhythm. Learners can use headphones plugged into the headphone jack to listen to music without affecting the normal learning process. At the same time, the gravity of the counterweight block itself will pull the top cover down, so that the top cover will not shake easily, preventing gaps from appearing between the top cover and the sealing gasket.

[0025] (3) A beat writing marking mechanism is provided, which uses a rotating cylinder and a disc to limit the position of the paper used, and uses a positioning frame to position the paper used for marking, so that the end of the marking pen can be attached to the surface of the paper. When the lifting block rises and falls with the rhythm of the music, the marking pen also rises and falls with it, and the marking pen will draw the changes of the rhythm on the paper to form rising and falling lines;

[0026] At the same time, the clamping magnetic block and the metal cylinder will clamp and fix one end of the paper, so that one end of the paper fits on the surface of the reel, and the driving motor will drive the reel to rotate together, and the reel can reel in the paper, pulling the paper forward. The paper continues to move forward, and the lines drawn by the marking pen on the paper will not be chaotic, so that the changes in the rhythm of the music can be completely drawn on the paper. In the subsequent learning process, you can learn music according to the rhythm lines drawn on the paper, which is convenient to carry with you for viewing and learning.

[0027] (4) A storage protection mechanism is provided, and the mounting side plate is locked and fixed by a locking knob and a stud, so that the protective cover is installed on the top of the bottom plate and wrapped around other structures, thereby providing storage protection for other structures of the device, preventing them from being hit by foreign objects or accidentally touched during idleness, and preventing dust from accumulating. The top of the protective cover has a stepped curved plate, which can serve as a seat during idleness, thereby increasing the utilization rate of the device, avoiding being placed aside and occupying space in daily life, and improving the adaptability of the device.

[0028] (5) The protective cover is pressed on the top of the movable block, so that the movable wheels bulge downward. When used as a seat or for transportation, the movable wheels can be directly used to push the device forward, and the movable block can move up and down inside the movable groove. When learning music, the protective cover is removed, and the movable block and the movable wheels move upward. The limiting magnetic block and the metal frame are attached to each other, which plays a role of limiting and fixing, so that the position of the movable block and the movable wheel rises, and the movable wheel is no longer in contact with the ground, and the bottom block is attached to the ground, which improves the stability of the device and prevents the device from sliding during use.
