[0024] During outdoor activities, people often need to carry a variety of portable devices to meet different needs. For example, handheld speakers are widely used to provide music playback to enhance the entertainment of outdoor activities; while handheld fans are used to provide cool air to alleviate the discomfort caused by high outdoor temperatures. However, existing handheld speakers and handheld fans have obvious limitations in terms of functionality and cannot meet users' comprehensive needs for multiple functions during outdoor activities. For example, handheld speakers can provide high-quality audio output, but they cannot provide any cooling function for users in high outdoor temperatures. Handheld fans can provide cool air, but they lack audio playback functionality and cannot meet users' needs to listen to music while enjoying a cool breeze.

[0025] Based on this, refer to Figures 1-5 As shown, this application embodiment provides a speaker structure 100, which includes a housing 10, a sound-emitting part 20, an air supply component 30, and a power supply component 50; wherein, as Figure 2As shown, the housing 10 has a receiving cavity 11 inside, and one side of the housing 10 has a first sound hole 131 that communicates with the outside and the receiving cavity 11. The sound-producing part 20 is installed in the receiving cavity 11, and the sound-producing part 20 is at least partially arranged opposite to the first sound hole 131 to ensure that the audio emitted by the sound-producing part 20 can be smoothly transmitted outward through the first sound hole 131, thereby optimizing the sound propagation effect.

[0026] It is understood that the sound-producing part 20 can be fixedly installed on the inner wall of the receiving cavity 11, or a bracket for installing the sound-producing part 20 can be provided in the receiving cavity 11. The sound-producing part 20 can be fixedly installed in the receiving cavity 11 by fasteners or adhesive to ensure the installation stability of the sound-producing part 20 in the receiving cavity 11.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 5 As shown, an air supply component 30 is installed on the outer casing 10. The air supply component 30 can blow air outward, so that the speaker structure 100 can provide cool air to the user in addition to audio playback. The user can selectively use the audio playback function or the air blowing function, or use both audio playback and air blowing functions at the same time, according to the user's needs. This significantly improves the convenience and comfort of the user during outdoor activities. Especially in high-temperature environments, the air supply function can provide cool air to the user and relieve the discomfort caused by the heat. It is particularly suitable for outdoor activities such as camping and hiking. Users can enjoy music while feeling the cool breeze.

[0028] In this embodiment, the speaker and fan functions are integrated into one device, reducing the number of devices that users need to carry and improving portability. Users can switch between or use these two functions simultaneously through simple operations to meet the usage needs in different scenarios.

[0029] In this embodiment, as Figure 2 , Figure 3 Figure 4 Figure 5 As shown, the air supply component 30 is installed on the housing 10 via the connector 40. One end of the connector 40 along its length is fixedly installed to the air supply component 30, while the other end of the connector 40 along its length is movably installed on the housing 10. Figure 4 As shown, the connector 40 is configured to allow the air supply component 30 to swing relative to the housing 10 around a fixed point, thereby adjusting the air supply direction of the air supply component 30 so that the air supplied by the air supply component 30 can diffuse in the desired direction to the surrounding area, thereby delivering cool air to the place where it is most needed according to the user's actual needs.

[0030] In this embodiment, the air supply component 30 can swing relative to the outer casing 10 around a fixed point and along a preset trajectory direction, or the air supply component 30 can swing relative to the outer casing 10 around a fixed point and in any direction.

[0031] For example, when the air supply component 30 oscillates relative to the housing 10 around a fixed point and along a preset trajectory, such as Figure 2 As shown, the air supply component 30 can be tilted relative to the outer casing 10 along the sound output direction of the sound-emitting part 20 (e.g., Figure 2 As shown, the sound output direction of the sound-emitting part 20 is the first direction X), which allows the cool air delivered by the air supply member 30 to blow directly onto the user's face. Since the common usage method when using the speaker structure 100 to play audio is to align the sound output direction of the sound-emitting part 20 with the user, that is, to make the first sound hole 131 face the user, the air supply member 30 can be tilted relative to the outer shell 10 along the sound output direction of the sound-emitting part 20, so that the air delivered by the air supply member 30 can be directly delivered to the user's face. This achieves the goal of providing a comfortable air supply experience by directly blowing cool air onto the user's face while the user is using the audio playback function. When it is necessary to adjust the air supply angle of the air supply member 30, the air supply member 30 is tilted from top to bottom or from bottom to top along the sound output direction of the sound-emitting part 20 to adjust the air supply angle of the air supply member 30 to the desired position.

[0032] For example, when the air supply component 30 swings around a fixed point and in any direction relative to the housing 10, that is, the air supply direction of the air supply component 30 is adjusted to any direction, thereby the air supply component 30 can cover a wider area and improve the air supply range.

[0033] In this embodiment, the air supply component 30 can be installed at the top of the housing 10, or it can be installed at other positions of the housing 10. Preferably, in this application, the air supply component 30 is installed at the top of the housing 10 via the connector 40, which allows the air supplied by the air supply component 30 to better cover the surrounding area and provide users with a wider range of cool air.

[0034] It is understood that the air supply component 30 in this application can be a low-noise fan, using a silent motor, which can significantly reduce the noise during fan operation. The silent motor reduces mechanical friction and electromagnetic noise by optimizing the structure and operation of the motor. The noise level of the low-noise fan is controlled below 45 decibels (dBA), which is equivalent to a quiet library or indoor environment and will not interfere with audio playback. Users can clearly hear music or voice content.

[0035] In this embodiment, the air supply component 30 includes a fan housing, fan blades installed inside the fan housing, and a motor, etc. One end of the connector 40 is fixedly connected to the fan housing, thereby enabling the air supply component 30 to be installed at the top position of the outer casing 10.

[0036] In this embodiment, the low-noise fan design ensures that the speaker is not disturbed by fan noise when playing audio, allowing users to enjoy a high-quality audio experience. When used outdoors or at home, the low-noise fan will not produce harsh noise, providing users with a more comfortable user experience.

[0037] In this embodiment, a power supply component 50 is provided in the receiving cavity 11. The power supply component 50 is used to provide power to the sound output part 20 and the air supply part 30. For example, the power supply component 50 can be a rechargeable battery, and a charging interface can be provided at a suitable position on the outer casing 10 so that users can charge it with a common charger.

[0038] Reference Figure 3 , Figure 4 , Figure 8 , Figure 10 As shown, in one embodiment of this application, a guide portion 133 is formed on the outer shell 10 to constrain the movement trajectory of the connector 40, so that the air supply member 30 can pitch and swing relative to the outer shell 10 along the sound output direction of the sound output member 20. The guide portion 133 is provided to limit the swing trajectory of the air supply member 30, so that the air supply member 30 can pitch and swing relative to the outer shell 10 along the sound output direction of the sound output member 20, thereby making the air supply direction of the air supply member 30 consistent with the audio playback direction, providing a more harmonious user experience.

[0039] Understandably, when it is necessary to adjust the air delivery angle of the air supply component 30 in the sound output direction of the sound-producing part 20, the user applies a force to the air supply component 30 and causes the connecting part 40 to swing relative to the outer shell 10 around a fixed point. Under the guidance and constraint of the guide part 133, the air supply component 30 swings from top to bottom or from bottom to top in the sound output direction of the sound-producing part 20, thereby achieving adjustment of the air delivery angle of the air supply component 30 in the sound output direction of the sound-producing part 20, so as to achieve more precise adjustment and meet the diverse needs of users in different scenarios.

[0040] In this embodiment, under the constraint of the guide portion 133, the air supply component 30 can tilt and swing relative to the outer shell 10 along the sound output direction of the sound output portion 20, thereby ensuring that the air supply direction of the air supply component 30 is consistent with the audio playback direction, so that the user can feel the cool air blowing directly on the face while enjoying music, providing a more comfortable user experience.

[0041] For example, the guide part 133 may be a groove structure, a track structure, or a guide rail structure, etc.

[0042] Reference Figure 4 , Figure 8 As shown, in one embodiment of this application, the outer shell 10 is provided with a first groove structure through its wall thickness direction. The first groove structure extends in a direction substantially consistent with the sound emission direction of the sound-emitting part 20, and the first groove structure forms the aforementioned guide part 133; as Figure 3 , Figure 5 As shown, the connector 40 includes a first rod 41. Along the length of the first rod 41, one end of the first rod 41 is fixedly connected to the air supply component 30, and the other end of the first rod 41 extends from the first groove structure into the receiving cavity 11. A ball structure 42 is provided at the end of the first rod 41 that extends into the receiving cavity 11. Figure 4 As shown, the receiving cavity 11 has a spherical cavity 60 that matches the size of the spherical structure 42. The spherical structure 42 is installed in the spherical cavity 60, allowing the spherical structure 42 to move freely within the spherical cavity 60. This enables the first rod 41 to swing relative to the outer shell 10 with the spherical cavity 60 as the swing point. Simultaneously, since the first rod 41 passes through the first groove structure, when the first rod 41 swings around the spherical cavity 60 as the swing point, it is simultaneously guided and constrained by the first groove structure. This causes the first rod 41 to drive the air supply component 30 to swing along the first groove structure. This allows the air supply component 30 to be tilted and adjusted relative to the outer shell 10 along the first groove structure with the first rod 41, enabling fine adjustment of the air supply angle of the air supply component 30 to meet the user's needs in different usage scenarios.

[0043] It is understandable that the first rod 41 is fixedly connected to the air supply component 30. The first rod 41 and the fan housing can be fixedly connected by fasteners or snap-fit ​​connections. For example, the first rod 41 and the fan housing can be fastened with bolts, screws, etc., or a snap-fit ​​groove can be provided on the fan housing, and a snap-fit ​​part that mates with the snap-fit ​​groove can be provided at the end of the first rod 41. The snap-fit ​​connection between the snap-fit ​​groove and the snap-fit ​​part is used to achieve the fixed connection between the first rod 41 and the fan housing.

[0044] In this embodiment, the user can adjust the air delivery angle of the air supply component 30 to the desired position in the air delivery direction of the sound unit 20 according to actual needs, so as to achieve the best air delivery effect; thus, the user can flexibly adjust the air delivery angle according to personal preferences and actual usage scenarios, providing a more personalized user experience.

[0045] In this embodiment, the cross-sectional shape of the first rod 41 can be set to a circle, an ellipse, a rectangle, etc.; and the dimension of the first rod 41 along the width direction of the first groove structure is set to be consistent with the width dimension of the first groove structure, or slightly smaller than the width dimension of the first groove structure; thus, when the user applies a force to the air supply component 30 and drives the air supply component 30 to swing relative to the outer shell 10, the first groove structure restricts the swing trajectory of the first rod 41, so that the air supply component 30 can swing relative to the outer shell 10 along a preset trajectory.

[0046] Understandably, if the dimension of the first rod 41 along the width direction of the first groove structure is slightly smaller than the width of the first groove structure, then during the swinging operation of the air supply component 30, the air supply component 30 will deviate slightly along the width direction of the first groove structure (but will still swing along the length extension direction of the first groove structure). At the same time, the periphery of the first rod 41 will not contact or will not be in constant contact with the inner wall of the first groove structure, which will also make it easier to drive the air supply component 30 to swing relative to the outer shell 10. If the dimension of the first rod 41 along the width direction of the first groove structure is equal to the width of the first groove structure, then during the swinging operation of the air supply component 30, the air supply component 30 will not deviate along the width direction of the first groove structure, but the periphery of the first rod 41 will be in constant contact with the inner wall of the first groove structure along its width direction and generate friction. This may require the user to apply a slightly larger force to drive the air supply component 30 to swing relative to the outer shell 10 in order to adjust the air supply direction.

[0047] In this embodiment, in order to achieve the positioning of the air supply component 30, that is, to ensure that the air supply component 30 can be stably maintained in the current adjusted position when it is swung to the required angle position, for example, a rubber damping pad can be covered on one side of the periphery of the first rod 41 and / or the inner wall of the first groove structure, so that the damping pad can press against the first rod 41 or the inner wall of the first groove structure. This achieves the positioning of the air supply component 30 by the friction of the rubber damping pad when it is adjusted to the required position; or a rubber damping pad can be provided between the ball structure 42 and the spherical cavity 60, which can also achieve the above positioning effect.

[0048] In this embodiment, as Figures 4-8As shown, an auxiliary guide 15 can be installed on the outer shell 10 and at the location of the first groove structure. The auxiliary guide 15 has a groove structure that matches the contour of the first groove structure (the first rod 41 passes through the auxiliary guide 15 and the first groove structure in sequence). This enables the air supply component 30 to swing relative to the outer shell 10 during the swing adjustment process. Through the coordinated cooperation of the auxiliary guide 15 and the first groove structure, the air supply component 30 can be supported, guided, and constrained to swing relative to the outer shell 10. Compared with relying solely on the first groove structure formed on the wall of the outer shell 10 to guide and constrain the movement trajectory of the air supply component 30, the air supply component 30 is more stable and smooth during the swing adjustment of the air supply angle, reducing the shaking or loosening caused by the swing.

[0049] It is understood that the auxiliary guide 15 can be made of engineering plastic or metal alloy. The auxiliary guide 15 can be fixed to the housing 10 by means of screws, adhesives or clips to ensure its stability and reliability.

[0050] Reference Figure 3 , Figure 4 , Figure 5 As shown, in one embodiment of this application, the connector 40 further includes a second rod 43, which is connected to the side of the ball structure 42 away from the first rod 41. The side of the spherical cavity 60 away from the first groove structure has a second groove structure 171, which is connected to the spherical cavity 60 and the receiving cavity 11. The extension direction of the second groove structure 171 is consistent with the movement trajectory of the second rod 43.

[0051] In this embodiment, through the cooperation of the second rod 43 and the second groove structure 171, when the air supply component 30 swings relative to the outer shell 10, the first rod 41 swings along a preset trajectory under the guidance and constraint of the first groove structure and the auxiliary guide 15. At the same time, the second rod 43 also swings along a preset trajectory under the guidance and constraint of the second groove structure 171. Thus, through the coordinated cooperation of the first rod 41, the first groove structure, the guide auxiliary component, the second rod 43, and the second groove structure 171, the air supply component 30 is supported, guided, and constrained to swing relative to the outer shell 10. This further improves the stability and smoothness of the air supply component 30 during the swing adjustment of the air supply angle, reduces the shaking or loosening caused by the swing, and ensures a smoother adjustment process of the air supply angle.

[0052] It is understandable that, such as Figure 3As shown, the second rod 43 can extend radially along the spherical structure 42 and be coaxially aligned with the first rod 41; or, the second rod 43 can extend only radially along the spherical structure 42 but not be coaxially aligned with the first rod 41, that is, the extension direction of the second rod 43 and the extension direction of the first rod 41 can be at a certain angle; regardless of whether the second rod 43 and the first rod 41 are coaxially aligned, the extension direction of the second groove structure 171 should match the movement trajectory of the second rod 43 when the first rod 41 swings, so that when the first rod 41 moves under the guidance and constraint of the first groove structure, the second rod 43 can move synchronously under the guidance and constraint of the second groove structure 171; thus, through the coordinated cooperation of the first groove structure and the second groove structure 171, the movement trajectory of the connecting member 40 is guided and constrained, thereby further improving the stability of the air supply member 30 when adjusting the air supply angle.

[0053] Reference Figure 4 , Figure 5 As shown, in one embodiment of this application, the speaker structure 100 further includes a first column 16 and a second column 17; wherein the first column 16 is disposed within the receiving cavity 11, and one axial side of the first column 16 is fixedly connected to the inner wall of the receiving cavity 11, a first semi-cavity 61 is formed within the first column 16, the side of the first semi-cavity 61 facing the first groove structure communicates with the outside through the first groove structure, and the side of the first semi-cavity 61 away from the first groove structure penetrates through the first column 16; it can be understood that the shape and outline of the first semi-cavity 61 are hemispherical; the second column 17 is connected to the side of the first column 16 away from the first groove structure, and a second semi-cavity 62 is formed within the second column 17, the second semi-cavity 62 penetrates through the side of the second column 17 facing the first column 16; it can be understood that the shape and outline of the second semi-cavity 62 are also hemispherical, thereby so that when the first column 16 and the second column 17 are joined together, the first semi-cavity 61 and the second semi-cavity 62 are joined together to form the aforementioned spherical cavity 60 (e.g. Figure 4 (As shown).

[0054] In this embodiment, the first column 16 and the inner wall of the receiving cavity 11 can be either separately connected or integrally connected. When the first column 16 and the inner wall of the receiving cavity 11 are separately connected, they can be fixed by fasteners (bolts, screws) or by snap-fit. The first column 16 and the second column 17 can be fixed by fasteners (bolts, screws), adhesive, or threaded connection to ensure the integrity and stability of the spherical cavity 60, thereby achieving the combination of the first half cavity 61 and the second half cavity 62 to form the spherical cavity 60.

[0055] Understandably, the first column 16 and the second column 17 are connected by fasteners, adhesive, or threaded connections to facilitate disassembly and assembly; and allow the second column 17 to be removed from the first column 16 when needed, and the spherical cavity 60 to be opened, so that users or maintenance personnel can easily maintain or clean the inside of the spherical cavity 60.

[0056] In this embodiment, as Figure 4 , Figure 5 As shown, the second groove structure 171 is provided through the second column 17 on the side away from the first column 16, so that the second rod 43 can pass through the second groove structure 171 and extend outward into the spherical cavity 60. This makes the second groove structure 171 and the first groove structure relatively independent, but they work together to support, constrain, and guide the movement trajectory of the connecting member 40.

[0057] Reference Figure 3 As shown, in one embodiment of this application, the first rod 41 is provided with a first channel 411 through its length direction, and the first channel 411 is connected to the space inside the air supply component 30. The spherical structure 42 is provided with a second channel 21 through its radial direction. The second rod 43 is provided with a third channel 431 through its length direction, and the third channel 431 is connected to the receiving cavity 11. The first channel 411, the second channel 421 and the third channel 431 are sequentially connected.

[0058] In this embodiment, the space inside the receiving cavity 11 is connected to the interior of the air supply component 30 through the first channel 411, the second channel 421 and the third channel 431 connected in sequence. Therefore, the wires can enter the interior of the air supply component 30 through the receiving cavity 11 through the channels and connect with the motor or other electronic devices inside the air supply component 30, thereby achieving the effect of powering the air supply component 30, avoiding exposed wires and ensuring the overall aesthetics of the speaker structure 100.

[0059] It is important to note that, such as Figure 5 As shown, after the wire passes through the aforementioned channel and enters the interior of the air supply component 30 through the receiving cavity 11, it is necessary to seal the end of the third channel 431 away from the second channel 421. That is, the third channel 431 is filled with a filler to isolate the receiving cavity 11 and the air supply component 30, so that the receiving cavity 11 forms a relatively sealed cavity to ensure that the sound-emitting part 20 has a better bass effect. Because the relatively sealed cavity can utilize the sound wave energy in the cavity to vibrate, thereby improving the overall efficiency of the speaker, especially in the low frequency part.

[0060] In one embodiment of this application, a damping pad may be provided on the inner wall of the first half-cavity 61, or on the inner wall of the second half-cavity 62, or on both the inner walls of the first half-cavity 61 and the second half-cavity 62. This allows the spherical structure 42 to be movably assembled into the spherical cavity 60, causing the peripheral sidewall of the spherical structure 42 to press against the damping pad. This results in a certain frictional resistance between the spherical structure 42 and the spherical cavity 60, thereby enabling the air supply component 30 to be stably positioned at the adjusted position under the action of friction after being swung and adjusted to the required angle position.

[0061] Understandably, the damping pad increases the frictional resistance between the spherical structure 42 and the spherical cavity 60, enabling the air supply component 30 to be stably positioned after swinging to the required angle, reducing accidental movement caused by external forces.

[0062] In this embodiment, grooves for installing damping pads can be formed on the inner walls of the first semi-cavity 61 and / or the second semi-cavity 62. When the damping pad is installed in the groove, its surface can slightly protrude from the inner wall of the first semi-cavity 61 or the second semi-cavity 62. This allows the spherical structure 42 to compress the damping pad when it is assembled into the spherical cavity 60, generating a large compressive force between the spherical structure 42 and the damping pad. This results in a certain amount of frictional resistance between the peripheral wall of the spherical structure 42 and the damping pad when the user drives the air supply component 30 to swing and adjust its angle. This also allows for adjustments to the air supply component 30 to the desired angle. When positioned, the air supply component 30 is located by the static friction between the ball structure 42 and the damping pad, preventing it from moving due to slight external forces or vibrations. At the same time, during the process of the air supply component 30 swinging relative to the outer casing 10 to adjust the air supply angle, a certain amount of frictional resistance between the ball structure 42 and the damping pad provides a good operating feel. Users can feel a certain resistance when adjusting the air supply angle. This resistance can enhance the user's control over the device and improve the overall user experience. It can also prevent the air supply component 30 from swinging excessively due to external forces during the adjustment process, ensuring that users can efficiently adjust the air supply component 30 to the required angle.

[0063] It is understood that the above-mentioned groove can also be provided on the peripheral surface of the ball structure 42, and the damping pad can be installed in the groove on the peripheral surface of the ball structure to achieve the same effect.

[0064] Understandably, the damping pad can be made of a material with a high coefficient of friction, such as rubber, silicone or other polymer materials, to ensure sufficient friction when the ball structure 42 comes into contact with the damping pad.

[0065] In this embodiment, the damping pad is provided between the spherical structure 42 and the spherical cavity 60, which can reduce the mutual transmission of vibration between the air supply component 30 and the sound-emitting part 20 to a certain extent, thereby providing users with a more stable user experience.

[0066] Understandably, the damping pad can effectively absorb and reduce the transmission of vibrations between the air supply component 30 and the sound source 20. This is because the air supply component 30 may generate certain vibrations during operation, and if these vibrations are transmitted to the sound source 20, they may affect the quality of audio playback. By reducing vibration transmission, the damping pad can ensure that the audio playback of the sound source 20 is clearer and reduce audio distortion or noise caused by vibration.

[0067] In one embodiment of this application, in the height direction of the outer casing 10, the outer casing 10 has a first end and a second end that are disposed opposite to each other, wherein the air supply member 30 and the first sound hole 131 are both disposed at the first end, and the second end forms a hand-held part.

[0068] In this embodiment, the air supply component 30 and the first sound hole 131 are located at the first end position, thereby enabling the user to hold the speaker structure 100 by holding the second end, thus achieving handheld carrying of the speaker structure 100. At the same time, since the first sound hole 131 is located at the first end position, it can be avoided that the user will block or cover the first sound hole 131 when holding the speaker structure 100, thus affecting audio playback. The air supply component 30 is located at the first end position, so that the hand holding part and the air supply component 30 maintain a sufficient distance, which will not affect the user's holding of the speaker structure 100, thereby improving the portability of the speaker structure 100.

[0069] Reference Figure 2 As shown in one embodiment of this application, the bottom of the outer casing 10 is flat in the height direction of the outer casing 10, and the flat surface is perpendicular to the height direction of the outer casing 10. This allows the user to place the speaker structure 100 on a table (such as a desktop, chair surface, etc.) when they do not need to hold it. This ensures that it can be placed independently and stably on various table surfaces. When the user does not want to hold the speaker structure 100, the user can easily place the speaker structure 100 on a desktop or other table surface without additional support or fixing devices, which improves the convenience of use.

[0070] Reference Figure 7 , Figure 8 , Figure 10 As shown, in one embodiment of this application, the outer shell 10 includes a front shell 13 and a rear shell 14, wherein the front shell 13 and the rear shell 14 are joined together to form the aforementioned receiving cavity 11 between the front shell 13 and the rear shell 14 (e.g., Figure 1As shown in the figure, the first sound hole 131 is formed on the front housing 13, so that the audio of the sound-producing part 20 is transmitted and diffused outward through the first sound hole 131 on the front housing 13.

[0071] It is understood that in this embodiment, the front housing 13 and the rear housing 14 can be connected and fixed by adhesive or by fasteners (bolts, screws, etc.). Adhesive bonding can provide a seamless appearance and improve the overall aesthetics of the product, while fastener connection can ensure a firm connection between the front housing 13 and the rear housing 14, while facilitating disassembly and reassembly and ensuring long-term stable operation of the equipment. In actual production, the appropriate connection method can be selected according to the requirements.

[0072] In this embodiment, the power supply component 50 is installed at the bottom of the receiving cavity 11 in the height direction of the outer shell 10, which can lower the center of gravity of the overall structure, ensure the stability of the speaker when placed, and reduce the risk of tipping over due to external force or accidental collision. For example, the power supply component 50 can be fixed at the bottom of the receiving cavity 11 by fasteners or buckles to ensure its stability and reliability.

[0073] In this embodiment, both the front housing 13 and the rear housing 14 are made of high-strength plastic materials, such as glass fiber reinforced ABS material. Glass fiber is a composite material in which glass fiber is added to ABS (acrylonitrile-butadiene-styrene copolymer) to enhance its structural strength, and the thickness can be set to 2mm. This allows the housing 10 to withstand the vibration of the motor in the sound-emitting part 20 and the air-blowing part 30. It also prevents the housing 10 from being accidentally dropped during use, which could cause structural damage or cracking.

[0074] In this embodiment, the low center of gravity design and flat bottom design reduce the risk of the speaker structure 100 tipping over due to external forces or accidental collisions during use, ensuring the safety of the device and the user.

[0075] Reference Figure 2 , Figure 9 As shown, in one embodiment of this application, the sound-producing part 20 includes an active sound-producing element (e.g., a loudspeaker with a diameter of 36mm and a power of 3W). The active sound-producing element is mounted on the front housing 13. A buffer 90 is sandwiched between the side of the active sound-producing element away from the front housing 13 and the rear housing 14. The buffer 90 can be connected to the active sound-producing element and the rear housing 14 by adhesive bonding.

[0076] In this embodiment, a buffer 90 is sandwiched between the active speaker on the side away from the front housing 13 and the rear housing 14. On the one hand, the buffer 90 can provide reliable mechanical support for the active speaker, reduce loosening caused by external force or vibration, and ensure the installation of the active speaker firmly; on the other hand, it can also reduce the vibration transmission of the active speaker when playing audio.

[0077] Understandably, the buffer 90 can absorb and reduce the vibrations generated by the active speaker during playback, preventing these vibrations from being transmitted to the housing 10, thereby reducing audio distortion and noise; by reducing vibration transmission, the buffer 90 can significantly improve the sound quality of audio playback, providing a clearer and purer sound.

[0078] In this embodiment, the buffer 90 can be a high molecular polymer material, such as EVA (Ethylene-Vinyl Acetate), which has good flexibility and elasticity.

[0079] Reference Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figure 9 As shown, in one embodiment of this application, the speaker structure 100 further includes a passive sound-emitting element 21, which is mounted on the front housing 13, as... Figure 2 As shown, in the arrangement direction of the front housing 13 and the rear housing 14, the passive sound-emitting element 21 divides the receiving cavity 11 into a first cavity 111 and a second cavity 112, wherein the active sound-emitting element is located in the first cavity 111, and the second cavity 112 has a second sound hole 132 that communicates with the outside.

[0080] In this embodiment, the passive sound-emitting element 21 is used to enhance the low-frequency response of the speaker structure 100. It does not contain a sound-emitting unit itself and assists the operation of the active sound-emitting element through its vibration, thereby improving the overall audio performance of the speaker structure 100. Specifically, the passive sound-emitting element 21 divides the housing cavity 11 into a first cavity 111 and a second cavity 112. The active sound-emitting element is located in the first cavity 111, and the first cavity 111 constitutes the rear cavity of the active sound-emitting element. When the active sound-emitting element (such as a speaker) is working, it will compress the air in the first cavity 111, forming a pressure change. These pressure changes act on the passive sound-emitting element 21, forcing the passive sound-emitting element 21 to vibrate, and its diaphragm radiates sound waves outward through the second sound hole 132, thereby enhancing the low-frequency response.

[0081] In this embodiment, as Figure 2As shown, both the active and passive sound-emitting elements 21 are mounted on the front housing 13 (that is, both the active and passive sound-emitting elements 21 are mounted on the same side of the speaker structure 100), and they are arranged vertically along the height of the housing 10. This ensures that the vibration directions of the active and passive sound-emitting elements 21 are consistent, and the sound waves can work together better to improve the low-frequency response. Alternatively, the passive sound-emitting element 21 can also be mounted on the rear housing 14, that is, it is mounted on a different side of the speaker structure 100 from the active sound-emitting element. However, in this case, the sound wave propagation paths of the active and passive sound-emitting elements 21 are different, resulting in a certain loss of sound wave energy, thereby reducing the low-frequency effect.

[0082] Understandably, the passive sound-emitting element 21 can be made of highly elastic and highly damped materials, such as rubber, silicone, polypropylene (PP), carbon fiber, glass fiber, etc., which have good vibration characteristics and acoustic performance. The passive sound-emitting element 21 can be set as a circle, ellipse or other suitable shape. The passive sound-emitting element and the front housing 13 can be installed on the front housing 13 by screws, clips or other fixing methods to ensure its stability and reliability. For example, the size of the passive sound-emitting element 21 can be 30mm-60mm, or other sizes, and its size is set according to the actual production needs.

[0083] In this embodiment, as Figure 2 , Figure 7 As shown, the speaker structure 100 also includes a circuit board 80, which can be placed on opposite sides of the power supply unit 50, thereby making full use of the space inside the housing cavity 11 and reducing mutual interference between the circuit board 80 and the passive sounding unit 21. The circuit board 80 is powered by the power supply unit 50 and is used to process and control audio signals and control the operation of the air supply unit 30, etc.

[0084] Reference Figure 6 , Figure 8 , Figure 9 As shown, in one embodiment of this application, the speaker structure 100 further includes a mesh cover 70, which covers the front housing 13 and at least covers the first sound hole 131 and the second sound hole 132.

[0085] In this embodiment, the grille 70 is provided to protect the active and passive sound-producing components 21, for example, from damage by dust, foreign objects, and physical impacts, thereby extending the service life of the speaker.

[0086] Understandably, the grille 70 should have a porous structure to ensure the free propagation of sound waves. The size and distribution of the pores should be optimized according to the acoustic design of the speaker structure 100. At the same time, the grille 70 should be made of acoustically transparent materials, such as fine-mesh metal mesh, fabric mesh, or plastic mesh. These materials allow sound waves to propagate freely, reduce sound wave reflection and absorption, and the materials should have sufficient strength and durability to withstand physical impacts and environmental influences during daily use.

[0087] In this embodiment, the mesh cover 70 can be fixedly installed on the front housing 13 by means of clips, screws or adhesive.
