[0040] In the description of the present invention, unless otherwise clearly defined, words such as setting and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0041] Reference below Figure 1A music playing method and a music playing device according to an embodiment of the present invention are described.

[0042] like Figure 1 As shown, a music playing device according to an embodiment of the present invention is described, comprising: a ball discharging mechanism 100 that releases the falling ball according to a certain rule; a feeding mechanism 300 that conveys the ball to the ball discharging mechanism 100; a sound-generating body 200, which can generate sound when driven by the falling ball; and a transmission mechanism 400 that drives and connects the feeding mechanism 300 and the ball discharging mechanism 100. In this embodiment, the sound-generating body 200 is a piano piece, and the ball falls from the ball-dropping device 130 onto the corresponding piano piece to make the piano piece generate sound. Different piano pieces are of different lengths, thereby generating different sounds, and the sound generated by the combination of different piano pieces forms a coherent tune.

[0043] Of course, depending on the actual situation, in some other embodiments, a drum body can also be used as a sound-producing component, and the ball hits the drum surface to produce sound; or strings can be used in conjunction with a lever mechanism to produce sound, and the ball falls to one end of the lever to lift the other end of the lever to touch the strings and produce sound.

[0044] In this embodiment, in order to allow the ball to slide into the ball-dropping device 130 by itself and prevent the ball from overflowing, Figure 2 As shown, the ball discharging mechanism 100 further includes a slideway 110 connected to the feeding mechanism 300 and arranged obliquely, a goal channel 120 connected to the slideway 110, and a plurality of ball dropping devices 130 connected to the lower end of the goal channel 120. The width of the slideway 110 gradually decreases from the end close to the feeding mechanism 300, and a guide plate 122 is also provided at the end connected to the goal channel 120. When the ball enters from the slideway 110 and hits the guide plate 122, it will enter the goal channel 120 along the guide direction. The goal channel 120 is provided with baffles 121 arranged at intervals, and the length of the baffles 121 gradually shortens from the middle to both sides. When the ball slides from the slideway 110 into the goal channel 120, it will first start to fill to the right side due to the inertia of the ball itself, and after the right side is filled, the ball will fill to the left side. The guide plate 122 and the wall plate 123 of the goal channel 120 form a channel through which the balls can pass. The channel is connected to the ball unloading channel 140. When the balls overflow, they can enter from the channel and then fall from the ball unloading channel 140, avoiding excessive accumulation of balls that may cause abnormal operation of the ball discharging mechanism 100.

[0045] Of course, according to actual conditions, in some other embodiments, the goal channel 120 may not be provided with the baffle 121 to divert the balls, so that all the balls enter the goal channel 120, and then the balls fill the ball falling device 130 under the action of gravity.

[0046] In this embodiment, in order to realize the function of collecting and transporting the spheres, as shown in FIG. Figure 5As shown, it also includes a rolling track 500 and a ball unloading channel 140. The sounding body 200 is tilted and located below the ball dropping device 130. The rolling track 500 is located on one side of the sounding body 200. The upper end of the ball unloading channel 140 is connected to the ball channel 120, and the lower end is connected to the rolling track 500. The rolling track 500 is connected to the feeding mechanism 300. The ball unloading channel 140 is semicircular and extends from top to bottom to the rolling track 500 at the bottom. The balls overflowing from the ball discharging mechanism 100 can fall from the ball unloading channel 140 to the rolling track 500, and the tilted bottom end of the sounding body 200 is connected to the rolling track 500. After the balls fall from the ball discharging device hit the sounding body 200, they roll along the tilted surface of the sounding body 200 to the rolling track 500. The balls finally gather at the position shown in FIG. Fig.10 The bottom portion shown is connected to the loading mechanism 300.

[0047] Of course, according to actual conditions, in some other embodiments, a cavity can be set at the bottom of the music playing device, and all the balls falling from the ball unloading track and the sounding body 200 can be gathered in the cavity. The cavity is inclined and connected to the bottom of the feeding mechanism 300. The balls falling into the cavity can be gathered at the feeding mechanism 300 and transported to the ball output mechanism 100 through the feeding mechanism 300.

[0048] In this embodiment, in order to transport the balls collected on the rolling track 500 to the ball discharging mechanism 100 at the top, as shown in FIG. Figure 7 and Fig. 9 As shown, the rolling track 500 also includes a curved goal track 510, which is connected to the side of the feeding mechanism 300. After the ball passes through the goal track 510, it slows down and enters from a side perpendicular to the rotation direction of the feeding mechanism 300. When the ball enters the goal track 510, the rolling speed can be reduced so that the ball will not fall out from the bottom of the feeding mechanism 300 due to excessive speed.

[0049] Of course, according to actual conditions, in some other embodiments, a rubber pad may be provided on the rolling track 500. When the ball passes through the rubber pad, the ball decelerates due to friction with the surface of the rubber pad.

[0050] In this embodiment, in order to control the automatic opening and closing of the falling ball, Figure 3 and Figure 4As shown, the ball drop device 130 includes a ball groove 131 connected to the lower end of the ball channel 120, a ball channel 132 arranged below the ball groove 131, a movable baffle 134 slidably arranged between the ball groove 131 and the ball channel 132, and a driving device 600 capable of driving the movable baffle 134 to move; the movable baffle 134 is provided with a ball hole 133. The ball enters the ball groove 131 through the ball channel 120, and the diameter of the ball hole 133 of the movable baffle 134 and the diameter of the ball channel 132 are larger than the diameter of the ball, so that the ball can smoothly pass through the ball hole 133 and the ball channel 132. The ball drop device 130 is also provided with a toggle block 135, and the toggle block 135 can push the movable baffle 134 to slide.

[0051] Of course, according to actual conditions, in some other embodiments, a screw motor can be used in conjunction with an infrared sensor to drive the movable baffle 134. When the infrared signal is blocked, the screw motor drives the movable baffle 134 to slide forward to open the channel. When the infrared signal is not blocked, the screw motor drives the movable baffle 134 to retreat to close the channel.

[0052] In this embodiment, in order to make the sound-generating body 200 emit sound according to a certain ball-falling pattern, such as Figure 3 and Figure 6 As shown, it also includes a plurality of groups of dial wheels 610, which are arranged coaxially and spaced and correspond to the ball-dropping device 130 one by one; the ball-dropping device 130 includes a reset member 137, and a plurality of dial teeth 620 are arranged on the periphery of the dial wheel 610. Rotating the dial wheel 610 can push the movable baffle 134 to slide, and make the ball hole 133 face the ball channel 132; the reset member 137 can push the movable baffle 134 to reset, and make the ball hole 133 staggered with the ball channel 132. The dial teeth 620 can mesh with the dial block 135. When the dial wheel 610 rotates, the dial teeth 620 mesh with the bottom of the dial block, thereby pushing the dial block to rotate, and then pushing the movable baffle 134 to move, opening the channel, so that the ball hole 133 is connected with the ball channel 132, and the ball falls onto the sound-generating body 200 to produce sound. When the toggle block 135 stops pushing, the movable baffle 134 moves backward due to the gravity of the reset member 137, the ball hole 133 and the ball channel 132 are misaligned, and the ball stops falling. A limit block 136 is also provided at the rear of the toggle block 135, and the toggle block 135 stops rotating when it rotates to the position of the limit block 136 under the gravity of the reset member 137.

[0053] Of course, according to actual conditions, in some other embodiments, black tape can be attached to the surface of the tuning wheel 610, and the ball dropping device 130 can be realized by cooperating with the infrared sensor and the screw motor in some other embodiments mentioned above; cardboard or polygonal plate can also be used to drive the movable baffle 134 to move, and the cardboard or plate can be coaxially spaced and cut at corresponding places on the periphery of the cardboard or plate according to the needs of self-composed music.

[0054] In this embodiment, if Figure 6 As shown, the position and number of the tuning teeth 620 on the tuning wheel 610 can be adjusted. The tuning teeth 620 are fixed on the tuning wheel 610 by being embedded in a slot or screwed directly, and the user can adjust the position of the tuning teeth 620 on the tuning wheel 610 according to the needs of composing music by himself.

[0055] In this embodiment, in order to transport the balls collected on the rolling track 500 to the ball discharging mechanism 100 at the top and to hook the balls to prevent the balls from accidentally falling off during transportation, Figure 7 and Figure 8 As shown, the loading mechanism 300 includes a transmission chain 310 and multiple sets of dribbling mechanisms 320, the dribbling mechanisms 320 are hook-shaped and fixedly connected to the transmission chain 310; the dribbling mechanisms 320 include an inner hook 321 close to the slide 110 and an outer hook 324 away from the slide 110; the inner hook 321 includes an L-shaped first hook member 322, and a first support portion 323 fixedly connected to the first hook member 322; the outer hook 324 includes an L-shaped second hook member 325, and a second support portion 326 fixedly connected to the second hook member 325, and the second support portion 326 is higher than the first support portion 323. Since the height of the second support part 326 is higher than that of the first support part 323, a groove is formed therebetween. The ball entering the groove can prevent the ball from rolling out of the outer hook 324. When the dribbling mechanism 320 is at the bottom, the ball enters the depression formed between the tips of the inner hook 321 and the outer hook 324. When the dribbling mechanism 320 is in an ascending state, the bottom of the ball contacts the groove, and the side has a depression and a protrusion 328 to prevent the ball from falling out.

[0056] In this embodiment, in order to prevent the ball from coming out from the side, Figure 8 As shown, the ball carrying mechanism 320 further includes a side baffle 327 , which is located between the inner hook 321 and the outer hook 324 and away from the first hook 322 and the second hook 325 .

[0057] In this embodiment, in order to prevent the ball from sliding into the slideway 110 at the top, as shown in FIG. Figure 8As shown, the ball-carrying mechanism 320 also includes a protrusion 328 disposed between the inner hook 321 and the outer hook 324. The lower end of the protrusion 328 is meshed with the gear, and the upper end is provided with an inclined protrusion. When the ball-carrying mechanism 320 is at the top, the bottom of the ball contacts the protrusion 328. At this time, since the upper end of the protrusion 328 is provided with a protrusion inclined toward the slideway 110, the ball is lifted up by the protrusion and falls into the slideway 110 to complete the conveying process. The lower end of the protrusion 328 is a part of the transmission chain that meshes with the gear, and the gear drives the lower end of the protrusion 328 to rotate the transmission chain.

[0058] In this embodiment, in order for the ball dribbling mechanism 320 to be able to grab the ball at the bottom of the feeding mechanism 300, Fig.10 As shown, the feeding mechanism 300 is also provided with a ball-carrying cavity 330, which is located below the transmission chain 310. The ball is located in the ball-carrying cavity 330 and can be hooked by the ball-carrying mechanism 320. The height of the ball-carrying cavity 330 is lower than the ball-carrying mechanism 320, just in the depression formed by the inner hook 321 and the outer hook 324. The ball stops moving after entering the ball-carrying cavity 330. Since the space of the ball-carrying cavity 330 can only accommodate one ball, when there is a ball in the ball-carrying cavity 330, the ball on the rolling track 500 cannot enter. When the ball is caught by the ball-carrying mechanism 320, the balls behind are automatically filled under the action of gravity, waiting for the next group of ball-carrying mechanisms 320 to catch.

[0059] In this embodiment, in order to drive the ball discharging mechanism 100 and the feeding mechanism 300, as shown in FIG. Fig.11 As shown, the transmission mechanism 400 includes a driving gear 410, a first transmission rod 420 rotatably connected to the driving gear 410, a plurality of driven gears 440 rotatably connected to the first transmission rod 420, and a handle 450. The driving wheel is rotatably connected to the handle 450, and the driving wheel is connected to the driven gear 440 through the first transmission rod 420. The driven gear 440 drives the feeding mechanism 300, and the gear coaxially arranged with the driven gear 440 meshes with the gear on the second transmission rod 430 to drive the second transmission rod 430 to rotate, and another gear on the second transmission rod 430 meshes with the dial wheel 610 to drive the dial wheel 610 to rotate, thereby enabling the ball discharge mechanism 100 to achieve the drop of the ball.

[0060] Of course, according to actual conditions, in some other embodiments, a motor may be rotatably connected to the driving gear 410 to realize automatic music playing of the music playing device.

[0061] In this embodiment, the method of playing music includes: making the ball move in a circular motion, and during the circular motion, letting the ball fall from a height according to a certain pattern, thereby causing the sound-generating body 200 to make a sound, thereby playing music. The ball slides into the ball-discharging mechanism 100, and enters the ball-dropping device 130 through the ball-dropping channel 120; turning the handle 450, driving the dial wheel 610 to rotate through the transmission mechanism 400, the dial wheel 610 pushes the dial block 135, thereby pushing the movable baffle 134 connected to the dial block 135, the movable baffle 134 pushes the reset member 137, and communicates with the ball channel 132 to make the ball fall onto the sound-generating body 200 at the corresponding position of the ball-dropping device 130, thereby making a sound; after the dial wheel 610 is separated from the dial block 135, the reset member 137 pushes the movable baffle 134 to make it misaligned with the ball channel 132, so that the ball in the ball groove 131 cannot fall; the ball slides from the sounding body 200 into the rolling track 500, and slides into the ball carrying mechanism 320 of the feeding mechanism 300 under the action of gravity; the conveyor chain drives the ball carrying mechanism 320 to the top, and the ball slides into the slideway 110 of the ball discharging mechanism 100 under the action of the inclined protrusion of the side plate and is backfilled into the ball dropping device 130. The overflowed ball enters the rolling track 500 through the ball unloading channel 140 to participate in the transportation cycle. The circular transportation of the ball is realized and the music is played by the ball hitting the sounding body 200.

[0062] The following describes in detail the working mode of a music playing method and a music playing device according to the present embodiment. It is worth noting that the following description is only an exemplary description and is not a specific limitation of the invention.

[0063] The user first puts the ball into the ball discharging mechanism 100, and the ball enters the ball dropping device 130 through the ball-dropping channel 120. Then the user turns the handle 450, and the transmission mechanism 400 drives the dial wheel 610 to rotate. The dial wheel 610 pushes the dial block 135, thereby pushing the movable baffle 134 connected to the crank of the dial block 135. The movable baffle 134 pushes the reset member 137 and communicates with the ball channel 132, so that the ball falls to the sounding body 200 at the corresponding position of the ball dropping device 130, thereby making a sound. After the dial wheel 610 is separated from the dial block 135, the reset member 137 is pushed and connected to the ball channel 132. The positioning member 137 pushes the movable baffle 134 to make it misaligned with the ball channel 132, so that the ball in the ball groove 131 cannot fall; the ball slides from the sound-generating body 200 into the rolling track 500, and under the action of gravity, slides from the rolling track 500 into the dribbling mechanism 320 of the feeding mechanism 300; the conveyor chain drives the dribbling mechanism 320 to the top, and the ball slides into the slide 110 of the ball discharge mechanism 100 under the action of the inclined protrusion of the side plate and is backfilled into the ball falling device 130, and the overflowed balls enter the rolling track 500 through the ball unloading channel 140 to participate in the transportation cycle.

The music playing device as a whole is composed of mechanical parts, and the structure is simple and easy to understand, easy to observe, full of fun, soothing, and improving the user's interest in use.

[0065] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
