Technical Field

[0001] The utility model relates to the field of science popularization exhibition preparation, in particular to a composition science popularization audition device. Background Technique

[0002] Music is a unique art form, and composition is the process of creating music. Composers create unique musical works through the combination and processing of notes. Note processing and phrase variation are common techniques in composition, which can bring rich layers and changes to the works. In composition, note processing refers to the process of making various changes and conversions to notes. Note processing can be achieved by changing aspects such as the pitch, duration, and timbre of notes.

[0029] As Figures 1 - 3 shown, this embodiment provides a composition popular science audition device, which includes a table body, a sound generator 16 and an upper end. The table body is arranged in a semi-circular table shape. The table body includes a front plate 11, side plates 12 and a rear plate 17. The front plate 11 and the rear plate 17 are two parallel and symmetric semi-circular plates. The front plate 11 and the rear plate 17 are connected by the side plates 12; a plurality of semi-circular lines 14 are arranged on the outer surface of the front plate 11, preferably five. The five semi-circular lines are concentric with the table body, that is, the five semi-circular lines have the same center as the front plate 11, and the distance between each adjacent two semi-circular lines 14 is the same. A plurality of slideways 13 are evenly arranged on the surface of the front plate 11. The extension lines of each slideway 13 intersect at the center position of the table body, and the distance between each adjacent two slideways 13 is the same; the intersection points of the semi-circular lines 14 and the slideways 13 are phonetic symbol points 131.

[0030] A plurality of note sliding components are evenly arranged inside the table body. Each slideway 13 is adapted to one note sliding component. The bracket in each note sliding component passes through the corresponding slideway 13. A note piece 21 is installed on the bracket so that the note piece 21 is placed on the outer wall of the front plate 11 and slides on the slideway 13. A sound generator 16 and three buttons 15 are arranged on the table body. The three buttons 15 are respectively electrically connected to the upper end. The upper end is pre-coded with three kinds of timbre information in advance. The sound generator 16 pre-records the tone sounds corresponding to each phonetic symbol point 131 under the three timbres. The upper end is pre-coded with the tone information corresponding to each phonetic symbol point 131. The sound generator 16 pre-records the tone sounds corresponding to each phonetic symbol point 131. The note sliding component and the sound generator 16 are electrically connected to the upper end. The sound generator 16 is similar to a player, which is prior art and will not be elaborated here.

[0031] Manually control the note piece 21 to slide on the slideway 13. When the note piece 21 slides to the phonetic symbol point 131, the rope encoder 23 in the note sliding component transmits a signal to the upper end, and the upper end controls the sound generator 16 to emit the tone corresponding to the phonetic symbol point 131 according to the signal.

[0032] In this embodiment, the three buttons 15 are respectively a first button, a second button and a third button. The first button corresponds to the first timbre, the first timbre is the piano timbre, the second button corresponds to the second timbre, the second timbre is the flute timbre, the third button corresponds to the third timbre, and the third timbre is the violin timbre.

[0033] When the first button is pressed, the upper end controls the sound generator 16 to switch to emit sound with the first timbre and the sound generator 16 sequentially emits the tones corresponding to each phonetic symbol point 131 from left to right under the first timbre;

[0034] When the second button is pressed, the upper end controls the sound generator 16 to switch to emit sound with the second timbre and the sound generator 16 sequentially emits the tones corresponding to each phonetic symbol point 131 from left to right under the second timbre;

[0035] When the third button is pressed, the upper end controls the sound generator 16 to switch to emit sound with the third timbre and the sound generator 16 sequentially emits the tones corresponding to each phonetic symbol point 131 from left to right under the third timbre.

[0036] The note sliding component includes a sliding mechanism, a positioning mechanism and at least one group of note mechanisms. The note mechanism and the positioning mechanism are installed on the sliding mechanism. The note mechanism slides on the sliding mechanism, and the positioning mechanism is used to limit the position of the note mechanism on the sliding mechanism.

[0037] The sliding mechanism includes a slide rail 222 and a mounting plate 22. The positioning mechanism includes a rack 221 and a gear 26;

[0038] The mounting plate 22 is vertically mounted on the inner wall of the rear plate 17. On one side of the mounting plate 22 perpendicular to the inner wall of the rear plate 17, a slide rail 222 and a rack 221 are mounted. The rack 221 is parallel to the slide rail 222. The extending direction of the rack 221 and the extending direction of the slide rail 222 are the same as the extending direction of the slideway 13. A slider 24 is slidably mounted on the slide rail 222.

[0039] There is at least one set of note mechanisms, and in this embodiment, there are two sets. The note mechanism includes a rope pull encoder 23 and a note member 21. The rope pull encoder 23 is mounted on one end of the mounting plate 22. The rope pull end of the rope pull encoder 23 is connected to the note member 21. The note member 21 is mounted on a bracket, and the bracket is mounted on the slider 24 through a mounting block 25. A gear 26 is mounted on the mounting block 25. The gear 26 is meshed and connected with the rack 221. When the note member 21 is manually pulled to make the note member 21 slide on the slide rail 222 through the slider 24, when the sliding stops, the gear 26 engages with the rack 221 to limit the note member 21 on the slide rail 222. That is, when the note member 21 is manually toggled to slide on the slide rail 222 through the slider 24, so that the note member 21 slides on the slideway 13, and when the hand is released when reaching the phonetic symbol point 131, the gear 26 engages with the rack 221 to limit the note member 21 at the phonetic symbol point 131.

[0040] The working process of the present utility model is as follows:

[0041] The note member 21 is manually toggled to make the note member 21 exposed on the outer surface of the front plate 21 slide in the slideway 13. When sliding to different phonetic symbol points 131, the rope pull lengths of the rope pull encoder 23 are different. The rope pull encoder 23 is electrically connected to the upper end. Different rope pull lengths of the rope pull encoder 23 transmit different signals to the upper end. The rope pull encoder 23 encodes different signals according to different rope pull lengths, which is the prior art and will not be elaborated here. That is, when the note member 21 slides to a certain phonetic symbol point, the rope pull encoder 23 encodes according to its own rope pull length and transmits the signal to the upper end. The upper end pre-encodes the tone information corresponding to each phonetic symbol point 131. When the rope pull encoder 23 transmits the signal to the upper end, the upper end controls the sound generator 16 to emit the tone sound corresponding to the phonetic symbol point 131 according to the corresponding information. The sound generator 16 pre-records in advance the tone sounds corresponding to each phonetic symbol point 131 in three timbres; when any one of the three buttons 15 is pressed, the three buttons 15 respectively correspond to three timbres. When a certain button is pressed, the upper end controls the sound generator 16 to adjust to the corresponding timbre. Taking the piano timbre corresponding to the first button as an example, each note member 21 is randomly toggled to a certain phonetic symbol point 131 and the first button is pressed. The upper end controls the sound generator 16 to switch to emit sounds in the piano timbre according to the signals of the rope pull encoder 23 and the first button, and the sound generator 16 sequentially emits the tone sounds corresponding to each phonetic symbol point 131 from left to right in the piano timbre to obtain a complete piece of music and complete the composition creation.

[0042] This solution is mainly designed based on the form of staff notation. Multiple sliding tracks are set on a semi-circular device, and note sliders are placed crosswise. Three different buttons are set to achieve three different timbres. The public can slide the note sliders to different positions on the staff notation and then continue to select the instrument buttons they want to hear. After starting, they will hear a short piece of self-composed work. This device can help people understand simple music theory knowledge, experience the technology in electronic sound effects, and feel the fun of music creation. By using the staff notation and movable note sliders, the public can participate in adjusting the positions of the notes to compose musical scores, which can enable the public to explore independently, inspire thinking about composition knowledge and be interesting. They can vividly understand what tones will be produced when notes are placed in different positions on the staff notation, and can also understand the differences between the music pieces made by different musical scores, having the significance of popular science teaching.
