Description

Technical Field

[0001] The utility model relates to the field of children's toys, in particular to a music player capable of automatically playing music and a carrier. Background Art

[0002] A music box is also called an eight-tone music box. It is a mechanical structure consisting of a metal sound tube and reeds. The sound tube has raised points distributed according to the music score. When it rotates, the raised points pluck different reeds to produce sounds of different pitches, forming a melody. The sound of a music box is very nice, but each music box can only play one fixed track, which will make you tired of it after listening to it for a long time.

[0003] Most of the existing paper tape music boxes punch holes in the paper tape, and then use the holes in the paper tape to replace the sound tubes of traditional music boxes. For example, the patent application "Music Box Using Punched Tape" (201510606378.0) by Shang Ping, uses a punched paper tape. When the paper tape passes between the roller and the tongue reed, the convex points (teeth) of the punched part can contact the tongue reed and make a sound, and the position without punched holes will not make a sound. Other similar patents include "A Music Box" (CN201820981267.7). The advantage of this type of music box is that it can change the music by punching holes, but it has the following shortcomings: 1) The paper tape needs to be equipped with a more specialized puncher, otherwise it is not easy to punch the hole position accurately, resulting in errors, and the punching errors cannot be repaired; 2) The unpunched part of the paper tape needs to be stuck with the convex points, which requires a higher hardness and requires more specialized paper, which is inconvenient for users to cut by themselves. 3) The paper is easy to wear out.

[0004] The utility model patent "An Electronic Music Device Capable of Composing Music Based on Color Ribbons" (201720021395.2) proposed by Zhu Jinhui et al. uses printing different colors on a paper tape to correspond to different musical scales. Eight color blocks of red, orange, yellow, green, blue, brown, purple, and pink respectively represent 8 notes. In addition, white is used as an empty note, and black is used as the start mark for color tape reading. The advantage of this patent is that it realizes printing colors on the paper tape to control the musical scales. However, there are also the following deficiencies: 1) General color printers have color deviations, and it is difficult to distinguish colors under different lighting conditions. For example, when orange is darker, it is easily recognized as brown; 2) The more musical scales need to be represented, the more colors need to be used, and it is more difficult to distinguish between them. Therefore, it is difficult to represent more complex scores; 3) A relatively good color sensor is required for identification, and the cost is relatively high. There are also some methods of using partial light source occlusion to control the brightness of the irradiated photoresistor to achieve some simple controls. The "Interactive Electronic Music Box" (CN201820700490.X) applied by Zhang Xiaoyu et al. and the patent with the same name (CN202220010583.6) applied by Zhong Yongwen both use the light brightness sensed on the photoresistor (moving the baffle or partially occluding the light passing hole) as a parameter for controlling the volume of the music box. In "A Fun Band Music Box Capable of Synchronizing Actions with Music" (CN201820873972.5) and "A Fun Band Music Box Capable of Synchronizing Actions with Music and Its Implementation Method" (CN201810578338.3) by Luo Qingjin et al., and "Volume Control Circuit and Electronic Music Box Based on Gesture Sensing" (CN201922272389.6) by Li Dongmei, the photoresistor is used to sense gestures (light intensity changes caused by changes) for controlling the volume or some specific actions. The photoresistor in "Paper Tape Music Box Clock" by Wang Ying et al. is mainly used to sense the small holes on the paper tape. Different small holes correspond to different times and are used to play the corresponding pre-recorded time-reporting music, which has nothing to do with the music itself. Summary of the Invention

[0030] The following will describe in detail the preferred embodiments of the present utility model with reference to the accompanying drawings so as to more clearly understand the purpose, features and advantages of the present utility model. It should be understood that the embodiments shown in the drawings are not limitations on the scope of the present utility model, but only to illustrate the essential spirit of the technical solution of the present utility model.

[0031] In the following description, for the purpose of illustrating various disclosed embodiments, certain specific details are set forth to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments can be practiced without one or more of these specific details. In other instances, well-known devices, structures, and techniques associated with the present application may not be shown or described in detail so as not to unnecessarily obscure the description of the embodiments.

[0032] References to "an embodiment" or "one embodiment" in the entire specification mean that the particular features, structures, or characteristics described in connection with the embodiment are included in at least one embodiment. Thus, the appearances of "in an embodiment" or "in one embodiment" in various places throughout the specification are not necessarily all referring to the same embodiment. Additionally, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0033] In the following description, in order to clearly show the structure and working mode of the present utility model, many directional terms will be used for description. However, words such as "front", "rear", "left", "right", "outer", "inner", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be understood as limiting terms.

[0034] The utility model inventor believes that the sound of a music box is very pleasant, but each music box can only play a fixed piece of music. To solve this problem, the inventor designed the first version of an electronic music player that can create music independently, which can solve the problem that traditional music boxes can only play a fixed piece of music. However, the first version of the music player needs to manually pull the carrier to move in order to play music. To achieve a good playback effect, it is necessary to control the speed of manual pulling to make it approximately uniform pulling, and the operation requirements are a bit high. To address this issue, the inventor developed the second version of the music player that can create music independently through continuous improvement of the work. It can play music automatically when the switch is turned on, and can also design the music score by itself to achieve the purpose of playing different music with one player. At the same time, users also have a high degree of participation. The following describes the music player 100 of an embodiment of the present utility model with reference to the accompanying drawings.

[0035] Figure 1 It is a schematic structural diagram of an automatically playable electronic music player 100 of an embodiment of the present utility model. Figure 2 It is a usage state diagram of the music player 100 of an embodiment of the present utility model. Figure 3 It is a side view of an automatically playable music player of an embodiment of the present utility model. As Figures 1 - 3 shown, the automatically playable music player 100 includes a photosensitive module 10, a light source module 20, a control module 30, a sound output module 40, and a driving module 90. The photosensitive module 10 reads the music score information by recognizing the colors on the carrier 50. The light source module 20 cooperates with the carrier 50 and increases the brightness of the carrier 50. The control module 30 is signal-connected to the photosensitive module 10 and receives the information sent by the photosensitive module 10. The sound output module 40 is signal-connected to the control module 30 and emits different pitches according to the instructions of the control module 30. The driving module 90 is connected to the carrier 50 and drives the carrier 50 to rotate, thereby playing the music score on the carrier 50.

[0036] In the present utility model, the music score information is recorded by the patterns on the carrier 50. The patterns can be set on the carrier 50 by means such as printing, copying, drawing, etc. Specifically, the carrier 50 has a disc shape (similar to a CD) and is provided with a plurality of circular tracks formed around the center of the disc and having different radii. Each circular track is provided with a plurality of patterns and corresponds to a pitch. The length of each pattern corresponds to the note length. The carrier 50 can be a paper carrier or other carriers made separately to record music scores, such as transparent plastic tapes, paper discs, etc. This is not limited herein. It can be understood that as long as the music score can be recorded by setting patterns on it, it can be applied to the present utility model. The sound output module 40 can be a speaker and some other sound processing modules.

[0037] Figure 4 is the front view of the carrier in an embodiment of the present utility model. Referring to Figure 4 as shown, the carrier 50 has a disc shape and is provided with a plurality of tracks 51 formed around the center of the disc on its surface and having different radii. Each track corresponds to a pitch, and a plurality of patterns are arranged on each track. The length of each pattern corresponds to the note length. Figures 3 - 4 The pattern in [[ ]] is a black arc-shaped block. However, those skilled in the art can understand that the pattern can also be other shapes. Optionally, the carrier 50 includes a transparent plastic disc and a paper disc disposed on the plastic disc. For example, the plastic disc is provided with a pin shaft, and the paper disc is provided with a pin hole. The paper disc and the plastic disc are fixed by inserting the pin shaft into the pin hole, which is convenient for disassembly and replacement. The music score on the paper disc can be printed or written on the printed empty ring, which is convenient for independent creation.

[0038] The driving module 90 can be, for example, a rotating motor. A rotating shaft hole 52 is provided at the center of the carrier 50. The rotating shaft 91 of the rotating motor passes through the rotating shaft hole 52 and is fixedly connected to the carrier 50. When the motor runs, the rotating shaft 91 rotates and drives the disc 50 to rotate evenly. When the driving module 90 drives the carrier 50 to rotate continuously, the photosensitive module 10 continuously identifies the music score on the carrier, and transmits the identified music score information to the sound output module 40 through the control module 30 to generate sound. Through the continuous rotation of the carrier 50, the pitch and note length of the music score identified by the photosensitive module 10 continuously change, so that the sound output module continuously emits different pitches and note lengths, and forms the music score music recorded on the carrier. If the motor does not stop rotating, the music on the disc will continuously loop. Optionally, the rotating motor is a reduction motor, and its rotation speed can be controlled by programming.

[0039] In Figures 3 - 4 the carrier shown, the inventor added some pauses, and not every grid is necessarily filled, so that two sounds of the same pitch can be distinguished.

[0040] It should be noted that the tracks on the carrier are not physical tracks, but are only defined for the convenience of description. They can be formed by, for example, drawing lines, or can merely be used to define the area of each pitch without drawing lines, and only need to paint patterns on different radius rings. In addition, since some simple music may only have seven pitch changes, therefore, only seven tracks need to be provided on the carrier to complete the recording of these simple music. However, for some complex music, seven pitches are far from enough to reflect it. Therefore, it can be achieved by setting multiple tracks on the carrier. For example, 14 tracks can record music with 14 pitches, 21 tracks can record music with 21 pitches, etc.

[0041] In order to facilitate acquisition and save costs, the music score information is represented by a black area set on the carrier. For example, the music score information is represented by a black arc block printed on the surface of the carrier. Preferably, the black arc block is as wide as the circular track and extends along the extension direction of the circular track. The extended length represents the length of the pitch of the track, for example, extending the length of "one beat", "two beats", etc. according to the content of the music score.

[0042] The utility model detects the music score information recorded on the carrier through the photosensitive module 10. Since the music score information on the carrier is recorded through patterns, in order to maintain the stability of the light and improve the recognition accuracy of the photosensitive module, the light source module is used for illumination. Therefore, the light source module 20 can be set at any position where the light source module can illuminate the carrier. For example, the light source module is set on the front side of the carrier and irradiated at the position recognized by the photosensitive module. However, through many experiments, the inventor arranged the light source module 20 and the photosensitive module 10 relative to each other and arranged the part of the carrier recording the music score between the photosensitive module 10 and the light source module 20, which can achieve a better recognition effect, that is, the light source module 20 is set on the front of the carrier 50, and the photosensitive module 10 is set on the back of the carrier 50, and the light intensity is increased by the transmission of the light source module 20 to the carrier. Optionally, the light source module 20 can be arranged on the back side of the carrier 50, and the photosensitive module 10 can be arranged on the front side of the carrier, and the two can be staggered at a certain angle. Compared with the solution of arranging the light source module and the photosensitive module on the same side, this can save more space occupied by the modules and make the layout more compact.

[0043] The inventor has tested that in a completely dark room, when the backlight of the mobile phone is adjusted to the darkest, the photoresistor is measured to be 1.18MΩ. The resistance value change of the photoresistor under various shielding conditions is tested under the soldering table lamp. The soldering table lamp is 10cm away from the photoresistor, and the shielding object is 0 away from the photoresistor. The records are shown in Table 1 below.

[0044] Table 1 Test of resistance value of photoresistor under different shielding objects

[0045]

[0046] As can be seen from the table above, the resistance difference between white paper and black ink is quite obvious, so they can be distinguished based on this characteristic. Optionally, the photoresistor can be a chip photoresistor. Since the pin-type photoresistor is larger in size, the chip photoresistor can further reduce the volume occupied by the music player.

[0047] In one embodiment, the photosensitive module 10 includes a first group of photosensitive resistors and a second group of photosensitive resistors. The first group of photosensitive resistors includes seven photosensitive resistors, and the seven photosensitive resistors respectively correspond to seven different pitches. The second group of photosensitive resistors includes at least one photosensitive resistor and is used to represent different pitch ranges. Correspondingly, the carrier 50 is provided with a first group of tracks and a second group of tracks extending in a circular direction. The first group of tracks corresponds to the first group of photosensitive resistors and includes seven tracks for corresponding to seven different consecutive pitches. The second group of tracks corresponds to the second group of photosensitive resistors and includes at least one track and is used to represent the pitch range. For example, whether there is a pattern on the second group of tracks corresponding to the photosensitive resistors on the carrier is detected by the photosensitive resistors in the second group to determine the pitch range. For example, if the second group of tracks has a pattern (such as a black rectangular block), it represents the high pitch range, and if there is no pattern, it represents the middle pitch range. Each pitch range on the second group of tracks corresponds to the seven pitches on the first group of tracks. Thus, the second group of photosensitive resistors including one photosensitive resistor can distinguish two pitch ranges, and combined with the seven pitches of the first group of tracks, fourteen pitches can be obtained to realize the playback of most sheet music. Similarly, if the second group of tracks includes two tracks and the second group of photosensitive resistors includes two photosensitive resistors, four pitch ranges can be realized. By combining the four pitch ranges with the seven pitches of the first group of photosensitive resistors, twenty-eight pitches can be obtained to meet the playback of most sheet music. For example Figure 4 The sheet music recorded on the carrier shown is "Happy New Year". A total of eight tracks are provided from the inside to the outside. The first group of tracks includes the 2nd - 8th tracks and is used to represent seven consecutive different pitches, such as "1, 2, 3, 4, 5, 6, 7". The second group of tracks includes the 1st track and is used to represent the pitch range. The high pitch range and the low pitch range are distinguished by whether there is a pattern on the 1st track. Combined with the seven pitches on the first group of tracks, fourteen pitches can be obtained.

[0048] In one embodiment, referring to Figure 5 , the light source module 20 includes a plurality of LED lights 21. The plurality of LED lights can be, for example, the same number as the photosensitive resistors and are arranged opposite to the photosensitive resistors in sequence. The part of the carrier 50 for recording the sheet music is arranged between the LED lights and the photosensitive resistors. Optionally, the LED lights are also selected as surface - mounted type to further reduce the volume occupied by the light source module and the photosensitive module.

[0049] Optionally, the control module 30 can select Arduino Nano or Microduino, both of which are open-source hardware products based on Arduino and are software-compatible. For example, when selecting Arduino Nano, the control module 30 includes an Arduino board, which has 8 analog input ports. The seven photosensitive resistors of the first group and the one photosensitive resistor of the second group of the photosensitive module are respectively connected to the eight input terminals of the Arduino board, and the one photosensitive resistor of the second group is connected to the analog signal input port of the Arduino board. Those skilled in the art need to understand that the control module 30 can have many implementation manners. For example, a 51 board or an ARM board can be used as long as any board with a microprocessor function can be used as the input module 30.

[0050] Optionally, referring back Figure 1 , the automatically playable electronic music player 100 may further include a power supply module 60, which is electrically connected to the control module 30, the light source module 20, the photosensitive module 10, and the driving module 90 to provide power for them. When in use, turn on the switch, the driving module 90 operates and drives the carrier to rotate at a constant speed. The photosensitive module 10 continuously reads the patterns (such as black rectangular blocks) on different tracks of the carrier and transmits the read information to the control module 30. The control module 30 controls the sound output module 40 to play the music score on the carrier 50.

[0051] Optionally, the automatically playable electronic music player 100 further includes a current regulation module 70. The input end of the current regulation module 70 is electrically connected to the power supply module 60, and the output end of the current regulation module 70 is electrically connected to the control module 30, the light source module 20, and the photosensitive module 10, so as to drive the motor to rotate through an independent drive circuit to provide sufficient power.

[0052] In one embodiment, the automatically playable electronic music player further includes a main body for carrying or installing the photosensitive module, the light source module, the control module, and the sound output module.

[0053] Another aspect of the present utility model also relates to a carrier for the above-mentioned automatically playable electronic music player. The carrier is used in cooperation with the aforementioned creatable electronic music player. The carrier has a disc shape and is provided with at least seven concentric annular tracks with different radii around the center of the disc. Each track corresponds to a pitch and is provided with a pattern, and the length of each pattern corresponds to the note length. The carrier can be formed by processing ordinary printing paper, for example, and can cover various music score information. From world famous works to pop music, all can be recorded on the carrier in the form of patterns. By cooperating with the automatically playable electronic music player of the present utility model, various types of music can be played.

[0054] In one embodiment, a first set of tracks and a second set of tracks are provided around the center of the disc. Among them, the first set of tracks includes seven tracks and is used to correspond to seven different consecutive pitches, and the second set of tracks includes at least one track and is used to represent the pitch range. By cooperating the first set of tracks with the first set of photosensitive resistors of the photosensitive module of the music player, and the second set of tracks with the second set of photosensitive resistors, recordings of up to 14, 21, 28, etc. pitches can be achieved, covering various musical scores.

[0055] In summary, the present utility model can use ordinary paper tape as a carrier to replace a tone cylinder, etc. to record musical scores. By a simple method of blackening blocks at different track positions to record musical scales, by adopting machine vision technology, photosensitive devices are used to sense the black blocks, and the Arduino module is used as a control module to process and output sounds to the sound output module. The user of the music player of the present utility model can create musical scores by himself and can automatically play the music on the carrier.

[0056] Therefore, the user of the present utility model can not only draw circular tracks on the paper tape and blacken the blocks to create musical scores independently, but also share the relevant music files by sharing the self-made carrier such as the paper tape. In addition, the carrier of the present utility model can be made of ordinary cardboard, which is convenient to obtain, cheap in price, low in cost, and convenient for users of all age groups to use.

[0057] The preferred embodiments of the present utility model have been described in detail above.

These equivalent forms also fall within the scope defined by the appended claims of this application.
