[0031] Please refer to Figure 1 , Figure 2 and Figure 3 The musical instrument 100 of this utility model includes a first housing 10 and a second housing 20. The second housing 20 and the first housing 10 form a receiving space 30. The second housing 20 is provided with a first receiving cavity 21 and a second receiving cavity 22. The depth of the first receiving cavity 21 is greater than the depth of the second receiving cavity 22, and the first receiving cavity 21 occupies more than or equal to two-thirds of the volume of the receiving space 30. A sound cavity module 40 is provided in the first receiving cavity 21.

[0032] In the musical instrument 100 of this embodiment, by designing a first accommodating cavity 21 and a second accommodating cavity 22, and placing the sound cavity module 40 within the deeper first accommodating cavity 21, more physical space is provided for the sound cavity module 40, thereby optimizing the sound quality performance of the musical instrument 100. Furthermore, the deeper first accommodating cavity 21 occupies more than two-thirds of the volume of the accommodating space 30, providing sufficient space for the sound cavity module 40, while the second accommodating cavity 22 can be used to accommodate other functional components. This achieves structural optimization within a limited space and avoids mutual interference between the sound cavity module 40 and other components.

[0033] Specifically, the musical instrument 100 can be an electronic keyboard, a guitar, or other musical instrument 100 with a sound cavity module 40. The first housing 10 and the second housing 20 are the outer shells of the musical instrument 100, which can provide physical support and protection for the internal modules of the musical instrument 100.

[0034] The housing space 30 provides physical space for the sound cavity module 40 and other modules. The housing space 30 can be designed in different shapes and sizes to accommodate the needs of different musical instruments 100.

[0035] The first receiving cavity 21 is a part of the receiving space 30, and has a greater depth, for placing the sound cavity module 40. The first receiving cavity 21 provides sufficient physical space for the sound cavity module 40, thereby ensuring the propagation and resonance of sound waves, and thus optimizing the sound quality performance of the instrument 100.

[0036] There is a depth difference between the first receiving cavity 21 and the second receiving cavity 22. This depth difference design ensures that the acoustic cavity module 40 has sufficient physical space while providing reasonable space allocation for other components. The depth difference can be achieved through mold manufacturing or machining to ensure that the depth ratio of the first receiving cavity 21 and the second receiving cavity 22 meets the design requirements.

[0037] The volume of the first receiving cavity 21 is substantially the same as the volume of the sound cavity of the musical instrument 100. The sound cavity module 40 within the first receiving cavity 21 can generate and amplify sound waves. The sound cavity module 40 may include a resonance cavity, a loudspeaker, or other acoustic components. The sound cavity module 40 can be installed within the first receiving cavity 21 by means of snap-fit, threaded connection, or other methods. For example, the sound cavity module 40 is connected to the second housing 20 by screws. By setting the volume of the first receiving cavity 21 to occupy more than or equal to two-thirds of the receiving space 30, the physical volume of the sound cavity within the musical instrument 100 is ensured, allowing the miniaturized musical instrument 100 to still have a large sound cavity, thereby improving the sound quality performance of the musical instrument 100.

[0038] Please refer to Figure 2 In some embodiments, the width of the second housing 20 gradually decreases from the middle of the second housing 20 to both ends.

[0039] Thus, the design of the second housing 20, whose width gradually decreases from the middle to both ends, provides a larger volumetric space 30 for the acoustic cavity module 40. This structural design allows the acoustic cavity module 40 to obtain more physical space in the central region, thereby improving sound quality performance.

[0040] Specifically, Figure 2 The dashed line A in the diagram indicates the centerline of the second housing 20. It can be seen that the width of the second housing 20 gradually decreases from dashed line A towards both ends. It should be noted that dashed line A is merely a schematic diagram for ease of understanding and should not be construed as limiting the embodiments of this utility model.

[0041] Please refer to Figure 4 In some embodiments, the instrument 100 further includes a battery module 50 disposed in the second receiving cavity 22, the volume of the battery module 50 being greater than or equal to one-third of the volume of the second receiving cavity 22.

[0042] Thus, the battery module 50 occupies more than one-third of the volume of the second receiving cavity 22, ensuring that the battery module 50 has sufficient physical space to accommodate a larger capacity battery. This design significantly improves the battery life of the instrument 100, enabling it to operate for longer periods and reducing the need for frequent charging.

[0043] Specifically, the battery module 50 is a module within the musical instrument 100 used to provide stable power support. The battery module 50 can be a lithium battery, a nickel-metal hydride battery, or other types of rechargeable battery, the specific choice depending on the musical instrument 100's battery life requirements and size limitations. The battery module 50 can be installed within the second receiving cavity 22 via snap-fit, threaded connection, or other methods. For example, the battery module 50 is connected to the second housing 20 via screws.

[0044] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the musical instrument 100 further includes a motherboard module 60, which is disposed in the second receiving cavity 22 and on one side of the battery module 50. The motherboard module 60 includes a paddle unit 61 and a heat sink unit 62, which are disposed on the side of the motherboard module 60 away from the battery module 50.

[0045] Thus, the motherboard module 60 is located on one side of the battery module 50, while the paddle unit 61 and the heat sink unit 62 are located on the side of the motherboard module 60 away from the battery module 50. This layout avoids direct contact between the motherboard module 60 and the battery module 50, thereby optimizing the internal space layout of the musical instrument 100, ensuring that the components do not interfere with each other, and improving the overall space utilization.

[0046] In addition, the heat sink unit 62 is located on the side of the motherboard module 60 away from the battery module 50, away from the heat that may be generated by the battery module 50, which helps to improve heat dissipation efficiency, prevent the motherboard module 60 from overheating, and thus extend the service life of the motherboard module 60.

[0047] Specifically, the mainboard module 60 is the electronic control center of the musical instrument 100, and may include circuit boards, electronic components, and other necessary components. Both the paddle unit 61 and the heat sink unit 62 can be mounted on the circuit board. The mainboard module 60 is used to control and coordinate the electronic functions of the musical instrument 100, such as audio processing and power management. The mainboard module 60 can be mounted within the second receiving cavity 22 via snap-fit, threaded connection, or other methods. For example, the mainboard module 60 can be snap-fitted to the second housing 20.

[0048] The pick unit 61 is a component in the musical instrument 100 used to pluck the strings. The pick unit 61 produces sound by plucking the strings and is one of the key components for playing the musical instrument 100. The pick unit 61 can be connected to the circuit board of the mainboard module 60 by means of adhesive bonding, threaded connection, etc. The pick unit 61 can be mechanical or electronic, and the specific design depends on the type and requirements of the musical instrument 100.

[0049] The heatsink unit 62 is a component used for heat dissipation. It can be made of metal and has good thermal conductivity. The heatsink unit 62 can be connected to the circuit board of the motherboard module 60 by means of bonding, threaded connection, etc. The heatsink unit 62 is spaced apart from the heatsink unit 61. The heatsink unit 62 dissipates the heat generated by the motherboard module 60, ensuring that the motherboard module 60 can still operate stably in high-temperature environments. The heatsink unit 62 can be made of aluminum, copper, or other high-efficiency heat dissipation materials.

[0050] Please refer to Figure 5 and Figure 6 In some embodiments, the motherboard module 60 further includes a card reader unit 63 and a microphone insertion unit 64, which are disposed on the side of the motherboard module 60 near the battery module 50.

[0051] In this way, by placing the card reader unit 63 and the microphone insertion unit 64 on the side of the motherboard module 60 close to the battery module 50, the spatial conflict with the heat sink unit 62 and the paddle unit 61 is avoided, the internal spatial layout of the musical instrument 100 is further optimized, so that the components do not interfere with each other and the overall space utilization is improved.

[0052] Furthermore, the card reader unit 63, being close to the battery module 50, can obtain power more stably, thereby improving the stability and efficiency of data transmission and ensuring the smoothness of the instrument 100 when reading and processing data. The microphone insertion unit 64, being close to the battery module 50, can ensure the stability of audio input, reduce audio distortion or interruption caused by unstable power output, and improve the quality of audio input.

[0053] Specifically, the card reader unit 63 is a unit used to read data from the memory card. The card reader unit 63 allows users to import or export data, such as audio files and sheet music, via the memory card, enhancing the functionality and portability of the musical instrument 100. The card reader unit 63 can be electrically connected to the circuit board of the motherboard module 60.

[0054] The microphone insertion unit 64 is an interface for connecting an external microphone. The microphone insertion unit 64 allows the user to record or input audio using an external microphone, enhancing the audio input functionality of the instrument 100. The microphone insertion unit 64 can be electrically connected to the circuit board of the motherboard module 60.

[0055] Please refer to Figure 1 and Figure 7 In some embodiments, the first housing 10 is provided with a through hole 11, and the paddle unit 61 includes a paddle body 610 and a shaft 611. The paddle body 610 passes through the through hole 11 and is rotatably mounted on the shaft 611.

[0056] Thus, the paddle body 610 passes through the through hole 11 of the first housing 10 and is rotatably mounted on the shaft 611. This design allows the paddle unit 61 to be easily rotated or adjusted, and the user can easily operate the paddle, improving the ease of use.

[0057] Specifically, the through hole 11 is a through hole that penetrates the first housing 10. The shape and size of the through hole 11 can be adjusted according to the design of the paddle body 610, such as waist-shaped, round or square.

[0058] The pick body 610 is the main part of the pick unit 61 and can be made of plastic, wood, or other materials suitable for plucking strings. The pick body 610 can directly contact the strings and produce sound by plucking them. The pick body 610 can be designed in different shapes and thicknesses to suit different playing needs, such as triangular or rectangular shapes.

[0059] The shaft 611 is the support structure for the paddle unit 61 and can be made of metal or other sturdy materials. The shaft 611 can be used to fix the paddle body 610 and allow the paddle body 610 to rotate on the shaft 611. The shaft 611 can be designed in different shapes and sizes, such as cylindrical or square, to accommodate different paddle body 610 designs.

[0060] The size of the through hole 11 is larger than the size of the paddle body 610. In this way, the through hole 11 can provide clearance space, thereby avoiding interference between the first housing 10 and the paddle body 610, preventing the paddle body 610 from malfunctioning, and ensuring the rotation range of the paddle body 610.

[0061] Please refer to Figure 7 In some embodiments, the first housing 10 is provided with a plurality of spaced-apart vent holes 12, which are connected to both the first receiving cavity 21 and the second receiving cavity 22.

[0062] Thus, the vent 12 provides a channel for sound wave transmission, allowing sound waves to propagate from inside the instrument 100 to the outside. Furthermore, the vent 12 allows air to circulate between the inside and outside of the instrument 100, aiding in heat dissipation. This is particularly beneficial when modules such as the battery module 50 and motherboard module 60 are located within the housing, effectively reducing internal temperature and extending the module's lifespan.

[0063] Specifically, the vent 12 can be a through hole penetrating the first housing 10. The vent 12 can be designed as circular, square, or rectangular, etc., and the specific shape and size are determined according to acoustic and heat dissipation requirements. The number of vents 12 can be two, three, four, or even more. The spacing can be uniform or non-uniform. The vents 12 can be arranged in a rectangular array, a circular array, or other arrangements.

[0064] Please refer to Figure 1 In some embodiments, the musical instrument 100 is a guitar, which includes a body 101 and a neck 102. The body 101 includes a first housing 10 and a second housing 20, and the neck 102 is detachably connected to the body 101.

[0065] Thus, the detachable connection between the neck 102 and the body 101 allows the guitar to be separated into two parts, significantly shortening its overall length and making it easier to carry and store. This design is particularly suitable for travelers or users who need to frequently transport the instrument 100. The detachable neck 102 design facilitates subsequent maintenance and replacement. If the neck 102 is damaged or needs upgrading, the user can replace the neck 102 separately without replacing the entire guitar, thereby reducing maintenance costs.

[0066] Specifically, a guitar is a stringed instrument 100 that produces sound by plucking its strings. The first shell 10 and the second shell 20 are the main structures of the body 101, together forming the housing space 30. Detachable connection means that the neck 102 and the body 101 can be connected by mechanical means such as threads, clips, or pins.

[0067] Please refer to Figure 1 and Figure 2In some embodiments, the width of a first position located on the side of the centerline A of the first receiving cavity 21 closer to the neck 102 is less than the width of a second position located on the side of the centerline A of the first receiving cavity 21 away from the neck 102, wherein the distance between the first position and the centerline A of the first receiving cavity 21 and the distance between the second position and the centerline A of the first receiving cavity 21 are equal.

[0068] Thus, the narrower width near the neck 102 helps stabilize the guitar's center of gravity when playing in a seated position, reducing fatigue from holding the guitar for extended periods. The wider width further away from the neck 102 provides a larger support area, allowing the string vibration energy to be transmitted more efficiently to the first receiving cavity 21.

[0069] Specifically, the first position can be any position on the side of the center line A of the first receiving cavity 21 closest to the neck 102. The second position can be any position on the side of the center line A of the first receiving cavity 21 furthest from the neck 102. Figure 1 and Figure 2 It can be seen that, in any two corresponding positions on both sides of the center line A of the first receiving cavity 21, the width of the first receiving cavity 21 corresponding to the position closer to the neck 102 is always smaller than the width of the first receiving cavity 21 corresponding to the position farther away from the neck 102.

[0070] Please refer to Figure 4 and Figure 5 In some embodiments, the second housing 20 is provided with an exhaust port 23, which communicates with the first receiving cavity 21 and is located on the side of the second housing 20 near the neck 102.

[0071] Thus, the design of the vent 23 reduces sound wave reflection and standing wave phenomena within the cavity, resulting in more uniform sound wave propagation and further improving sound quality. The vent 23 is connected to the first receiving cavity 21, allowing sound waves to flow freely inside and outside the cavity, effectively preventing the sound from being "muffled" and making the sound clearer and more natural.

[0072] In addition, the neck 102 is the high-pitched area of ​​the guitar. When the sound waves propagate from the neck 102 area, the vent 23 is close to the neck 102, which can optimize the propagation path of the sound waves, make the propagation of the sound waves inside and outside the cavity more uniform, and reduce sound wave reflection and standing wave phenomena.

[0073] Specifically, the vent 23 can be a through hole penetrating the second housing 20. The vent 12 can be designed as circular, square, or rectangular, etc. The number of vent 23 can be one or more, for example, two, three, four, or even more.

[0074] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0075] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
