Description

Technical Field

[0001] This utility model relates to the field of science popularization exhibits technology, specifically to a multi-instrument combination sound simulation device based on laser marking. Background Technology

[0002] Science and technology exhibition halls usually have related musical instruments on display for visitors to enjoy.

[0003] For example, patent document CN202473019U discloses an interactive musical instrument demonstration device, including a playing device connected to a control system, which in turn is connected to a signal input system. The device also includes a display system connected to the control system. The playing device may be one or more.

[0004] When using the aforementioned device, visitors first send commands to the interactive musical instrument demonstration device via the signal input system. The control system within the device then activates the playing apparatus to perform the corresponding piece. Visitors can select different pieces or input different note commands through the signal input system to play the corresponding melody.

[0005] However, the device only mentions "issuing commands through a signal input system," which, according to the conventional thinking of technicians, might be understood as a traditional button, keyboard, or touchscreen. This approach appears dull and lacks immersion for an "interactive demonstration device" designed to attract visitors. Visitors cannot obtain an engaging physical interactive experience strongly related to the theme of "instrument" or "music." The interaction feels more like operating a computer than "playing" an instrument, resulting in low interactivity and engagement. Utility Model Content

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a multi-instrument combination sound simulation device based on laser marking. Visitors can switch between different instruments and trigger the corresponding sounds through simple interactive operations, transforming the abstract instrument selection into a concrete spatial positioning operation, which enhances the fun of the experience and is suitable for immersive experiences in exhibitions and public spaces.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A multi-instrument combination sound simulation device based on laser marking includes:

[0009] Exhibition booth;

[0010] Musical instrument components are arranged in multiple sets and circumferentially in an array on the display stand;

[0011] The turntable is mounted on the display stand and is arranged coaxially with multiple musical instrument components.

[0012] The sign component is mounted on the turntable and moves with it.

[0013] The drive assembly is located on the display stand and connected to the turntable drive.

[0014] The sound-generating component is mounted on the display stand and electrically connected to the musical instrument components;

[0015] When the identifier component is driven to point to any group of musical instrument components, the sound-emitting component emits the sound corresponding to that group of musical instrument components.

[0016] As a further aspect of this utility model: the device also includes multiple sets of sensors, which are arranged in a circumferential array at the bottom of the display stand and are respectively arranged in correspondence with multiple musical instrument components. The overall structure formed by the multiple sets of sensors and the overall structure formed by the multiple sets of musical instrument components are coaxially arranged, and each set of sensors and each set of musical instrument components are located on the same radial direction. The marking component includes a sensing block, which is arranged on a turntable. The sensing block can move to the working range of any sensor as the turntable rotates.

[0017] As a further embodiment of this utility model: the marking component also includes a support arm on the turntable, and a cantilever is provided on the support arm, and an angle-adjustable laser head is provided on the cantilever, and the pointing light of the laser head interacts with any musical instrument component on the projection of the laser head onto the display stand.

[0018] As a further embodiment of this utility model: the display stand is provided with a frame, and a first rotating shaft arranged vertically is provided on the frame. The top of the first rotating shaft is used for coaxial installation of the turntable, and the top of the frame is used for circumferential array installation of multiple sets of sensors. The projection of each set of sensors on the display stand is located on the same radial direction as the musical instrument assembly.

[0019] As a further embodiment of this utility model: the driving component includes an operating panel that is rotatably mounted on the display stand. The operating panel is connected to the first rotating shaft via a transmission mechanism, and a handle is eccentrically mounted on the operating panel.

[0020] As a further embodiment of this utility model: the transmission mechanism includes a first bevel gear coaxially disposed at the bottom of the operating panel, and a second rotating shaft is rotatably disposed on the display stand at a position between the operating panel and the first rotating shaft. One end of the second rotating shaft is provided with a second bevel gear, and the second bevel gear meshes with the first bevel gear for transmission. The other end of the second rotating shaft is connected to the first rotating shaft through a right-angle reducer.

[0021] As a further embodiment of this utility model, the device also includes a transparent cover disposed on the top of the frame, and the transparent cover is used to cover the turntable and the marking components therein.

[0022] As a further embodiment of this utility model: the sound-generating component includes a speaker installed in the booth, and the speaker and the sensor are electrically connected through a control device.

[0023] As a further embodiment of this utility model: the musical instrument assembly also includes six buttons on the display stand, the six buttons are arranged radially along the trajectory circle formed by the rotation of the musical instrument assembly, and the buttons are electrically connected to the sound system through a control device.

[0024] As a further aspect of this utility model, the sensor is a positioning sensor.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. By arranging multiple instrument components in a circumferential array and combining them with a coaxial turntable and sign components, an intuitive and fun physical interaction method is created. Visitors can drive the components to rotate the turntable, so that the sign components point to different instruments, thereby triggering the corresponding sound. This transforms the abstract instrument selection into a concrete spatial positioning operation, enhancing the interactivity and fun of the experience.

[0027] 2. By using a circumferential array of sensors in conjunction with sensing blocks on a turntable, precise conversion from mechanical position to electrical signal is achieved. Each sensor is located on the same radial direction as its corresponding musical instrument, ensuring extremely high accuracy of the trigger signal when the sensing block rotates with the turntable into the range of any sensor. This avoids false triggering and ensures that the interactive response matches the visitor's intended operation. Figure 1 To.

[0028] 3. Based on precise triggering, the adjustable-angle laser head can accurately project the beam onto the currently selected instrument component, providing the operator with clear and intuitive visual feedback. The addition of this laser head not only enhances the sense of technology, but also makes the interactive process more performative and entertaining, greatly improving the attractiveness of the device and the user experience.

[0029] 4. The design of the frame and the first rotating shaft provides a stable, robust and highly integrated support platform for the entire rotation recognition system. At the same time, precision components such as the turntable and sensor array are integrated into an independent module, ensuring that the radial alignment accuracy of all sensors and instrument components can be fixed during assembly, simplifying the overall structural design.

[0030] 5. The off-center grip allows users to comfortably and effortlessly rotate the control panel. The mechanical transmission drives the turntable, making this physical operation more ceremonial and interactive than buttons or touchscreens. It also allows users to better control the rotation speed and angle of the turntable, enhancing their sense of participation.

[0031] 6. Building upon the basic direct triggering, the device adds richer performance possibilities for each instrument. The six radially arranged buttons are equivalent to providing multiple "keys" with different pitches or timbres for each instrument. After selecting an instrument, users can also play simple melodies, greatly expanding the device's musical expressiveness and interactive depth, upgrading the experience from "on-demand" to "playing".

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0052] like Figures 1-5 As shown, the multi-instrument combination sound simulation device based on laser marking includes booth 1, which is divided into two functional areas, with... Figure 5 Taking the state shown as an example, the circular area on the left can be defined as the interactive area, and the circular area on the right can be defined as the display area.

[0053] Multiple sets of musical instrument components 2 are set up in the display area, arranged in a circumferential array. This layout can be determined by... Figure 5 This is used for representation. Simultaneously, a sound-generating component (not shown in the diagram) is also installed in the display area. This component is electrically connected to the instrument component 2. Each instrument component 2 represents a different instrument (distinguished by text labels, etc.). Therefore, multiple instrument components 2 represent multiple types of instruments, and each instrument can produce sound through the sound-generating component. This article... Figure 5 The example shown illustrates the configuration of instrument component 2 as twelve groups.

[0054] Furthermore, a turntable 3 is installed in the display area, forming a coaxial layout with multiple instrument components 2. An indicator component 4 is mounted on the turntable 3, moving with its rotation. A drive component 5 is installed in the interactive area, which can drive the turntable 3 to rotate, thus changing the position of the indicator component 4. When a visitor uses the drive component 5 to rotate the turntable 3, the indicator component 4 rotates. When the indicator component 4 points to a specific instrument component 2, the sound-emitting component emits the corresponding sound, allowing the visitor to experience the fun of the instrument through interactive operation. If the turntable 3 continues to rotate and completes one full rotation, the indicator component 4 will sequentially point to multiple instrument components 2. Each time it points to a specific instrument component 2, the sound-emitting component emits the corresponding sound, allowing the visitor to experience the auditory impact of different instrument components 2.

[0055] Regarding the aforementioned labeling component 4, the labeling component 4 includes multiple sets of sensors 401, preferably positioning sensors. The multiple sets of sensors 401 are fixedly arranged in a circumferential array on the display stand 1. This state can be achieved by... Figure 4To illustrate, multiple sets of sensors 401 are arranged in a one-to-one correspondence with multiple musical instrument components 2. The overall trajectory circle formed by the multiple sets of sensors 401 is coaxially arranged with the overall trajectory circle formed by the multiple sets of musical instrument components 2, and the radius of the former trajectory circle is smaller than the radius of the latter trajectory circle. At the same time, each set of sensors 401 and each set of musical instrument components 2 are located on the same radial direction.

[0056] Furthermore, the marking component 4 also includes a sensing block 402, which is disposed on the turntable 3. The sensing block 402 can move within the working range of any sensor 401 as the turntable 3 rotates. The aforementioned marking component 4 moves with the rotation of the turntable 3, which is the rotation of the sensing block 402; the sensor 401 does not participate in the rotation. When the visitor drives the turntable 3 to rotate, when the sensing block 402 on the turntable 3 moves into the working range of any sensor 401, since each group of sensors 401 and each group of musical instrument components 2 are arranged in the same radial direction, the sensing block 402 will point to the musical instrument component 2 at this time, informing the visitor of the type of musical instrument component 2 corresponding to the sound emitted by the sound-producing component.

[0057] In order for the identification component 4 to more clearly identify the corresponding musical instrument component 2, the identification component 4 also includes a laser head 405 set on the turntable 3. The position of the laser head 405 needs to ensure that the projection of the pointing light emitted by it on the display stand 1 intersects with any musical instrument component 2. That is, when the sensing block 402 rotates with the turntable 3 into the working range of the sensor 401, the pointing light emitted by the laser head 405 will also point to the musical instrument component 2 corresponding to the sensor 401. Clear pointing can be achieved through the pointing light.

[0058] Regarding the installation of the laser head 405 on the turntable 3, this application provides a support arm 403 on the turntable 3, a cantilever 404 on the support arm 403, and the laser head 405 on the cantilever 404. Preferably, the angle of the laser head 405 on the cantilever 404 is adjustable to achieve multi-directional marking of the laser head 405 pointing the light. This adjustable angle is a conventional setting in the prior art, for example, the laser head 405 is damped and hinged to the cantilever 404, which will not be elaborated here to avoid cumbersome writing.

[0059] With the addition of the laser head 405, this application allows the sensing block 402 to be positioned at the bottom of the turntable 3. Therefore, the overall trajectory circle formed by the multiple sensors 401 will also be located below the turntable 3. The layout of the sensing block 402 and the single set of sensors 401 can be adjusted by... Figure 3 In this state, the working range of sensor 401 is the area above it. When sensing block 402 rotates with turntable 3 to the area above it, the two are connected.

[0060] To enable the installation of the turntable 3 on the display stand 1, this application includes a frame 6 fixedly installed in the display area. A first rotating shaft 7 is rotatably installed within the frame 6, arranged vertically with its top higher than the top of the frame 6. The turntable 3 is coaxially mounted on the top of the first rotating shaft 7. This frame 6 allows for the installation of multiple sets of sensors 401. Since the sensors 401 located at the top of the frame 6 are higher than the musical instrument assembly 2, to ensure that each set of sensors 401 and each set of musical instrument assemblies 2 are arranged in the same radial direction, the projection of each set of sensors 401 onto the display stand 1 is aligned radially with the musical instrument assembly 2. Vertically, each set of sensors 401 and the musical instrument assembly 2 are located on the same vertical plane.

[0061] For the transmission connection between the drive assembly 5 and the turntable 3, the drive assembly 5 can be configured to include an operating disk 501 rotatably mounted on the display stand 1. The operating disk 501 is connected to the first rotating shaft 7 via a transmission mechanism, and a handle 502 is eccentrically mounted on the operating disk 501. Visitors can rotate the operating disk 501 by holding the handle 502, and the rotation of the operating disk 501 will drive the turntable 3 to follow through via the transmission mechanism, thus achieving interaction. The transmission mechanism can be any transmission component in the prior art. For example, the transmission mechanism includes a first bevel gear 8 coaxially mounted at the bottom of the operating disk 501, and a second rotating shaft 10 rotatably mounted on the display stand 1 at a position between the operating disk 501 and the first rotating shaft 7. One end of the second rotating shaft 10 is provided with a second bevel gear 9, and the second bevel gear 9 meshes with the first bevel gear 8 for transmission. The other end of the second rotating shaft 10 is connected to the first rotating shaft 7 via a right-angle reducer 11. The right-angle reducer 11 allows visitors to avoid the discomfort caused by excessively fast rotation, enabling them to experience the best rotational feel at slower speeds. Simultaneously, the right-angle reducer 11 can proportionally reduce the rotational speed, allowing visitors greater precision control.

[0062] In order to protect the turntable 3 and the sign component 4, this application provides a transparent cover 12 on the top of the frame 6. The material of the transparent cover 12 can be transparent acrylic.

[0063] Regarding the above-mentioned sound-generating component, the sound-generating component includes a sound-producing part (such as a conventional part like a speaker). The sound-producing part is preferably located inside the display stand 1. The sound-producing part is electrically connected to the sensor 401 through a control device (not shown in the figure). When the sensing block 402 rotates into the working range of the sensor 401, the sensor 401 transmits a signal to the control device, and the control device reacts, causing the sound-producing part to emit the sound of the musical instrument component 2 corresponding to the sensor 401.

[0064] Specifically, in order to enhance the interactive experience of visitors, this application sets the musical instrument component 2 to include six buttons 201 on the display stand 1. The six buttons 201 are arranged radially along the trajectory circle formed by the rotation of the musical instrument component 2, and the buttons 201 are electrically connected to the sound system through a control device. The six buttons 201 are respectively set to six tones.

[0065] Under normal interactive conditions, visitors hold the handle 502 to rotate the control panel 501, which causes the sensor block 402 on the turntable 3 to conduct to a certain sensor 401. The musical instrument component 2 corresponding to the sensor 401 then emits sound through the speaker. When the musical instrument component 2 is further subdivided into buttons 201, visitors can press any number of buttons 201, indicating that the musical instrument component 2 will only play according to the pitch corresponding to the pressed button 201, making the sound production more interesting.

[0066] In addition, to further distinguish the types of instruments represented by different instrument components 2, the corresponding instrument graphics can be printed on the surface of button 201 when button 201 is set as described above.

[0067] It should be noted that the control device can be any applicable computing device, such as a personal computer, server, programmable logic controller (PLC controller), microcontroller, etc., or it can be an integration of computer devices. The control device has functions such as receiving information and sending control commands. The control device can control the sound system to perform corresponding sound-producing actions through wired or wireless communication.

[0068] This invention is merely a hardware platform constructed by connecting physical components together via a circuit structure. In practical use, the sensing between the sensor and the sensing block, and the coordinated sound generation between the sensor and the sound-generating component, are all extremely conventional linkage methods in the field of electronic sensing. The sensors, sensing blocks, and sound-generating components can all be commercially available parts. In use, this device can cooperate with existing software to achieve the identification and sound generation of the sensing block. However, it must be pointed out that the software used with this device is neither an innovative part of this invention nor a component of it.

[0069] With the combined action of the software, this utility model can separately realize the identification and sound generation of the sensing blocks, so that visitors can switch between different musical instruments and achieve interlaced sound effects through simple interaction. However, the protection of this utility model only extends to the hardware combination consisting of physical components and wires, and does not involve the improvement and protection of the software.

[0070] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
