Description

Technical Field

[0001] This invention relates to the field of audio technology, and more particularly to a three-way portable speaker with a screen and a smart device. Background Technology

[0002] Audio equipment is a common appliance in people's daily lives, serving to amplify and reproduce sound. Traditional audio systems are prone to phase distortion due to speaker placement. When listening to music, the narrow optimal listening area of ​​the speakers leads to additional binaural effects, resulting in poor music reproduction. A three-way speaker system is an audio system that uses dedicated speaker units to handle each frequency band. A crossover divides the audio signal into three frequency bands: low frequency, mid frequency, and high frequency. The woofer handles the low-frequency range, the midrange unit handles the mid-frequency range, and the tweeter handles the high-frequency range. Three-way speakers are commonly found in Hi-Fi audio products, and the specific frequencies of the different units give the music a richer sense of layering.

[0003] In existing technologies, common three-way speakers are relatively expensive due to the use of multiple speakers and crossovers. At the same time, due to the design requirements of the sound wave propagation path, three-way speakers are generally large in size, which contradicts the design concept of small size and low cost of portable speakers. Therefore, it is difficult to improve the sound quality of portable speakers through three-way technology.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] To address the problems of high cost and large size of existing three-way speakers due to the use of multiple speakers and crossovers, which make them unsuitable for portable speakers, this invention provides a three-way portable speaker with a screen and a smart device.

[0008] The aforementioned three-way portable speaker with a screen, wherein the two tweeters are symmetrically arranged with respect to the center line connecting the two woofers; The two woofers are symmetrically arranged relative to the center line connecting the two tweeters.

[0009] The aforementioned three-way portable speaker with screen includes a circuit box inside the enclosure, which contains a power supply and functional components. The circuit box is positioned to avoid the corresponding spaces of the tweeter, woofer, and passive radiator. The outer wall of the circuit box and the internal space of the enclosure form the sound guide cavity.

[0010] The aforementioned three-way portable speaker with screen has a cover on the side of the mounting panel facing the outside of the enclosure, the cover housing the tweeter and the woofer, and the cover is mesh.

[0011] The aforementioned three-way portable speaker with screen has two sliding grooves on the mounting panel facing the inside of the enclosure, and a limit tray is detachably installed in the sliding groove. The mounting panel has a first clearance hole, and the limiting tray has a second clearance hole including a stepped slot. The stepped slot clamps the passive basin at the position corresponding to the first clearance hole.

[0012] The aforementioned three-way portable speaker with screen has a handle on the mounting panel corresponding to one side of the enclosure. The center of the handle corresponds to the first clearance hole, and both ends of the handle are fixedly connected to the limiting tray by bolts passing through the mounting panel. The handle has a clearance hole at its center, which corresponds to the position of the passive basin.

[0013] The aforementioned three-way portable speaker with screen includes a plurality of microphone storage compartments inside the housing, with one side of the opening of each microphone storage compartment being fixedly connected to the bottom plate of the mounting slot. Several microphone storage compartments are symmetrically arranged inside the housing relative to the two mounting panels; When the cover is fastened into the mounting slot, the cover covers the openings of several microphone storage compartments.

[0014] The aforementioned three-way portable speaker with screen, wherein the cover is hinged, snapped, or engaged with the mounting slot; the screen is disposed on the side of the cover facing the mounting slot; When the cover covers the openings of several microphone storage compartments, the microphones inside the microphone storage compartments are spaced at a predetermined distance from the cover.

[0015] A smart device, wherein the smart device includes the aforementioned three-way portable speaker with a screen.

[0016] The beneficial effects of this invention are as follows: By setting a tweeter component along a first direction on the playback panel of the speaker enclosure, setting a woofer component along a second direction on the playback panel, and setting passive radiators on two opposing mounting panels, the sound waves from the tweeter and woofer components are reinforced by overlapping through the sound guide cavity and diffused by the passive radiators, forming a deep bass effect. This can simulate a three-way frequency response mode to enhance sound quality, achieving the effect of improving the sound quality of portable speakers with small size and low cost. The inner side of the mounting slot of the speaker enclosure is used to reflect sound waves, and the outer side is used to install a screen, effectively meeting the outdoor use needs of portable speakers.

Detailed Implementation

[0019] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0020] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0022] In existing technologies, common three-way speakers are relatively expensive due to the use of multiple speakers and crossovers. At the same time, due to the design requirements of the sound wave propagation path, three-way speakers are generally large in size, which contradicts the design concept of small size and low cost of portable speakers. Therefore, it is difficult to improve the sound quality of portable speakers through three-way technology.

[0023] To address the aforementioned problems in the prior art, this invention provides a three-way portable speaker with a screen, such as... Figure 1 As shown, the three-way portable speaker with screen includes: a cabinet 100, an assembly slot 110 on one side of the cabinet 100, a cover detachably mounted on the assembly slot 110, and a screen mounted on the cover; the cabinet 100 includes a playback panel 130 and mounting panels 150 located at opposite ends of the playback panel 130, a tweeter assembly 200 arranged in a first direction and a woofer assembly 300 arranged in a second direction on the playback panel 130, and two passive radiators 400 mirror images mounted on the two mounting panels 150; a sound guide cavity 101 is formed inside the cabinet 100, and the tweeter assembly 200 and the woofer assembly 300 correspond to the two passive radiators 400 through the sound guide cavity 101.

[0024] This invention provides a tweeter component 200 along a first direction on the playback panel 130 of the enclosure 100, a woofer component 300 along a second direction on the playback panel 130, and passive cones 400 on two opposing mounting panels 150. The sound waves from the tweeter component 200 and the woofer component 300 are reinforced by overlapping through the sound guide cavity 101 and diffused by the passive cones 400, creating a deep bass effect. This can simulate a three-way frequency response mode to enhance sound quality, achieving improved sound quality in a small size and at low cost. The inner side of the mounting slot 110 of the enclosure 100 is used to reflect sound waves, and the outer side is used to mount a screen, effectively meeting the outdoor use requirements of portable speakers.

[0025] In the above embodiments, such as Figure 1 As shown, the main body of the three-way portable speaker with screen of the present invention consists of a cabinet 100, a cover, a tweeter assembly 200, a woofer assembly 300, and a passive radiator 400. The cabinet 100 is the outer shell structure of the portable speaker. In this embodiment, the cabinet 100 is integrally formed with some structures being detachable to ensure that the sound guide cavity 101 inside the cabinet 100 has a good reflection effect on sound waves. In actual installation, the detachable structure on the cabinet 100 is the playback panel 130. By disassembling the playback panel 130, the interior of the cabinet 100 is exposed for the installation of components, and it is convenient to install the tweeter assembly 200 and the woofer assembly 300 on the playback panel 130.

[0026] The enclosure 100 also includes a mounting slot 110 on the top plate, which faces outwards from the enclosure 100. Correspondingly, a cover plate 120 can be detachably mounted on the mounting slot 110, and a screen is mounted on the cover plate 120. The screen is used to control the outdoor speaker or display content set by the user. The shape of the screen is adapted to the shape of the mounting slot 110, so that the mounting slot 110 can store the screen, which can prevent the screen from being damaged by bumps and knocks when the portable speaker is used outdoors. In addition, the user can adjust the positional relationship between the screen and the mounting slot 110 to facilitate operation and viewing.

[0027] In this embodiment, the main components for achieving a three-way sound effect are a tweeter assembly 200, a woofer assembly 300, and a passive radiator 400. The tweeter assembly 200 is used to play high-frequency sounds, the woofer assembly 300 is used to play low-frequency sounds, and the passive radiator 400, also known as a passive radiator, moves by the driving force generated by the compression of air inside the enclosure 100 when the active unit (tweeter assembly 200 and woofer assembly 300) is working. By increasing the vibrating area, more air is pushed, thereby enhancing the low-frequency output and lowering the low-frequency limit. Compared with traditional bass reflex speakers, speakers with a passive radiator 400 do not have high-speed airflow through narrow pipes, thus completely avoiding airflow noise and assisting the sound played by the active unit. Since the frequency of the sound effect formed by the passive radiator 400 is lower, it can achieve a three-way sound effect when used in conjunction with the tweeter assembly 200 and the woofer assembly 300.

[0028] In this embodiment, as Figure 1 As shown, the tweeter component 200 and the woofer component 300 are mounted on the playback panel 130 of the enclosure 100, which is a detachable side wall of the enclosure 100. The playback panel 130 faces upwards when in actual operation for user use. Specifically, the tweeter component 200 is positioned at a predetermined location on the playback panel 130 along a first direction, and the woofer component 300 is positioned at a predetermined location on the playback panel 130 along a second direction. On the one hand, this can create a sound effect of mixed high and low frequency waves with a relatively close sound source distance on the outside of the enclosure 100, which can prevent phase distortion and binaural effects. On the other hand, the sound waves can be amplified in the sound guide cavity 101 inside the enclosure 100, thereby increasing the amplitude of the passive diaphragm 400 and improving the passive generation effect of the passive diaphragm 400. In this embodiment, two passive radiators 400 are mounted on two mounting panels 150, which are specifically located at both ends of the playback panel 130 and are positioned opposite each other. The two passive radiators 400 are mirror images of the two mounting panels 150, thereby ensuring that the sound output of the passive radiators 400 at both ends of the enclosure 100 is identical. In actual use, the subwoofers generated by the passive radiators 400 assist the tweeter assembly 200 and the woofer assembly 300, making the overall sound quality fuller and more layered. The layout of the tweeter assembly 200 and the woofer assembly 300 is preset to ensure that the propagation path of sound waves in the sound guide cavity 101 is optimized, thereby reducing sound loss and distortion. At the same time, the mirror image arrangement of the passive radiators 400 not only balances the sound pressure distribution at both ends of the enclosure 100, but also further enhances the depth and power of the low-frequency response, bringing users a more immersive listening experience.

[0029] Based on the above embodiments, in one possible implementation of the present invention, such as Figure 1 and Figure 2As shown, the tweeter assembly 200 includes two tweeters 210, with the center line connecting the two tweeters 210 arranged along a first direction, which is parallel to the height direction of the playback panel 130. The woofer assembly 300 includes two woofers 310, with the center line connecting the two woofers 310 arranged along a second direction, which is parallel to the length direction of the playback panel 130.

[0030] The two tweeters 210 are symmetrically positioned relative to the center line connecting the two woofers 310, and vice versa. This arrangement ensures that the playback sources for the tweeters and woofers are positioned in a cross shape on the playback panel 130, creating a balanced coverage area during sound wave propagation and effectively preventing sound deviation and imbalance. The symmetrical distribution of the tweeters 210 and woofers 310 not only optimizes the uniformity of the sound field but also further enhances the overall sound quality, making its playback effect more stable and natural in different environments, and improving the clarity and layering of the sound. Simultaneously, the symmetrical design also helps to balance the sound pressure distribution inside the enclosure 100, enhancing the overall stability and durability of the speaker.

[0031] In one possible embodiment of the present invention, such as Figure 1 As shown, the aforementioned enclosure 100 contains a circuit box 500, which houses a power supply and functional components. The power supply may specifically be a battery, and the functional components may specifically be a memory, processor, frequency divider, etc. It should be noted that, for example... Figure 3 and Figure 4 As shown, in this embodiment, the two tweeters 210, two woofers 310, and two passive radiators 400 should be arranged in the same horizontal space. Correspondingly, the circuit box 500 needs to avoid the space of the tweeters 210, woofers 310, and passive radiators 400. The advantage of this arrangement is that, on the one hand, the internal space between the outer wall of the circuit box 500 and the inner wall of the enclosure 100 forms a sound guide cavity 101, effectively utilizing the limited space inside the enclosure 100. This ensures that the propagation path of the sound waves in the sound guide cavity 101 is not interfered with by the circuit box 500, and ensures that the reflection and propagation of the sound waves correspond to the passive radiators 400. On the other hand, it can ensure the compactness of the internal structure of the speaker, thereby meeting the characteristics of a small outdoor speaker structure.

[0032] In this embodiment, as Figure 1 and Figure 2As shown, to ensure that the two tweeters 210, two woofers 310, and two passive radiators 400 correspond to the same horizontal space, in this embodiment, the diameters of the two woofers 310 and the two passive radiators 400 are preferably matched, and the center points of the two woofers 310 and the two passive radiators 400 are located on the same horizontal plane. Simultaneously, the diameters of the two tweeters 210 are preferably less than half the diameter of the woofers 310, allowing the two tweeters 210 to be symmetrically distributed on both sides of the horizontal plane where the center point of the woofers 310 is located. This compact layout of the two tweeters 210 not only saves space inside the enclosure 100 but also further optimizes the propagation efficiency of sound waves within the sound guide cavity 101. By reducing the diameter of the tweeters 210, the impact of their vibrations on the air inside the enclosure 100 is more concentrated, thereby reducing mutual interference with the sound wave propagation path of the woofers 310. Furthermore, the horizontal alignment of the center points of the woofer 310 and the passive radiator 400 allows low-frequency sound waves to form a more regular standing wave pattern within the sound guide cavity 101, enhancing the depth and power of the low-frequency response. This design, while ensuring sound clarity, also improves the overall acoustic performance of the speaker, making it better suited for complex outdoor environments.

[0033] Furthermore, a cover 140 is provided on the side of the mounting panel 150 facing the outside of the enclosure 100. The cover 140 can be multi-layered and made of different materials to achieve different functions and appearance effects. The cover 140 covers the tweeter 210 and the woofer 310. The cover 140 not only protects the tweeter 210 and the woofer 310, preventing dust, liquids, etc. from the external environment from entering the enclosure 100 and affecting the performance of the components. Specifically, the cover 140 is mesh-like and made of a material with a certain degree of rigidity, such as plastic or metal. At the same time, its surface can be treated with a coating material to reduce the interference of sound wave reflection on sound quality. On the one hand, it ensures that the sound can be transmitted clearly, and on the other hand, it prevents the cover 140 from loosening or falling off due to bumps or collisions during outdoor use. In addition, the shape of the cover 140 can be set with a certain curvature to conform to the aerodynamic principle, reduce wind resistance during actual use, reduce noise generation when the portable speaker is used outdoors, and further improve the user experience.

[0034] In one possible embodiment of the present invention, such as Figure 5As shown, to facilitate the installation of the passive basin 400 and to enable easy maintenance and replacement, two sliding grooves 410 are provided on the side of the mounting panel 150 facing the inside of the housing 100. A limiting tray 420 is detachably installed in the two sliding grooves 410. The limiting tray 420 is used to install and fix the passive basin 400. In actual installation, a first clearance hole 151 is provided on the mounting panel 150. The shape and size of the first clearance hole 151 are adapted to the passive basin 400, so that the passive basin 400 can be installed and fixed. The sound-emitting surface of the cone 400 can be fully exposed on the outside of the enclosure 100; correspondingly, a second clearance hole 421 is provided on the limiting tray 420, and a stepped groove 422 is provided around the edge of the second clearance hole 421. The stepped groove 422 is used to install the passive cone 400, so that the passive cone 400 is fixed on the limiting tray 420 in a fitting manner. When the limiting tray 420 is installed to the predetermined position in the slide groove 410, the stepped groove 422 clamps the passive cone 400 in an interference fit at the position corresponding to the first mounting hole.

[0035] In this embodiment, the shape and size of the second clearance hole 421 are also adapted to the passive diaphragm 400. After the passive diaphragm 400 is engaged in the stepped slot 422, the second clearance hole 421 fully exposes the side of the passive diaphragm 400 that receives sound waves (i.e., the side corresponding to the inside of the housing 100), so that the passive diaphragm 400 can fully receive sound waves from the sound guide cavity 101 and generate vibration.

[0036] In this embodiment, the limiting tray 420 not only simplifies the installation and disassembly process of the passive radiator 400, avoiding the uncertainty brought about by the use of glue in the prior art to the quality of portable speakers, but also improves the accuracy and stability of assembly, preventing the passive radiator 400 from falling off due to wind and rain erosion when the portable speaker is used outdoors. Furthermore, the slide groove 410 structure enables a modular assembly method, further enhancing the flexibility and maintainability of the speaker's internal structure. In actual operation, the user only needs to push the limiting tray 420 in or pull it out along the slide groove 410 to complete the replacement or repair of the passive radiator 400, significantly reducing the reliance on professional tools and techniques. In other possible embodiments, the edge of the limiting tray 420 can also be sealed with gaskets to prevent dust and foreign objects from entering the interior of the enclosure 100, avoiding contamination or interference to the sound guide cavity 101 and other components.

[0037] More specifically, such as Figure 2 and Figure 5As shown, to facilitate the movement and transportation of the portable speaker, a handle 600 is provided on the side of the mounting panel 150 corresponding to the outside of the cabinet 100 in this embodiment. The handle 600 can be made of materials such as rubber. During actual installation, the center of the handle 600 is located corresponding to the first clearance hole 151. The two ends of the handle 600 are fixedly connected to the limiting plate by bolts passing through the mounting panel 150. With this structure, on the one hand, the handle 600 can be stably installed, and on the other hand, the first clearance hole 151 can facilitate the user to hold the handle 600. On the other hand, the limiting plate 420 can be fixed at the same time as the handle 600, thereby preventing the limiting plate 420 from sliding relative to the slide groove 410 after the portable speaker is bumped or knocked.

[0038] Furthermore, a clearance hole 610 is provided at the center of the handle 600, corresponding to the position of the passive basin 400. The clearance hole 610 ensures that the passive basin 400 is not affected by the structure of the handle 600 during operation, guaranteeing the normal propagation and vibration effect of sound waves. Simultaneously, the edges of the clearance hole 610 are designed with a smooth transition to avoid stress concentration caused by sharp edges, thereby improving the durability of the handle 600. An anti-slip texture can also be provided on the surface of the handle 600 to further enhance the comfort and stability of the user's grip, especially in complex outdoor environments, effectively preventing accidental slippage due to sweaty or slippery hands.

[0039] In another possible embodiment of the invention, such as Figure 1 As shown, the aforementioned housing 100 may also be equipped with several microphone storage compartments 700. One side of the opening 710 of each microphone storage compartment 700 is fixedly connected to the bottom plate of the mounting slot 110 (i.e., the top plate of the housing 100), and the bottom plate of the mounting slot is partially hollowed out to expose the opening 710 of the microphone storage compartment 700. The microphone storage compartment 700 is used to store microphones or other small audio devices, effectively securing the microphone and preventing collisions and damage caused by speaker movement or vibration. In this embodiment, the microphone storage compartments 700 should be symmetrically arranged inside the housing 100 relative to the mounting panel 150 to prevent the arrangement of the microphone storage compartments 700 from affecting the different sound output of the left and right passive radiators 400. When the cover is fastened in the mounting slot 110, the cover covers the openings 710 of several microphone storage compartments 700, thereby blocking the openings 710 of the microphone storage compartments 700. In actual use, when the user uses the portable speaker outdoors, the cover fastened in the mounting slot 110 protects the microphone device in the microphone storage compartment 700 from wind and rain. After the user opens the cover 120, the microphone device in the microphone storage compartment 700 can be quickly accessed, making it convenient for the user to operate and use.

[0040] In the above embodiments, the microphone storage compartment 700 may also be provided with functional components such as a charging structure, a clamping structure, and an elastic buffer structure to achieve the function of charging or further securing the microphone device. This application is not limited in this regard. Furthermore, based on this structural configuration, when the cover covers the openings 710 of several microphone storage compartments 700, the microphones inside the microphone storage compartments 700 are spaced a predetermined distance from the cover. That is, the cover does not limit the microphone's position; the microphone is limited by other structures. This structural configuration avoids contact between the microphone and the screen on the cover, thereby preventing damage to the microphone or screen caused by collisions when the portable speaker is subjected to bumps or impacts.

[0041] Specifically, in this embodiment, the cover and the mounting slot 110 are connected by means of hinge, snap-fit, or snap-fit. In actual installation, for example, the cover can be hinged to the mounting slot 110, allowing the user to expose or cover the opening 710 of the microphone storage compartment 700 by rotating the cover. Alternatively, the cover can be snapped to the mounting slot 110, meaning the cover is separate from the housing 100, allowing the user to expose or cover the opening 710 of the microphone storage compartment 700 by removing or placing the cover on the housing 100. Alternatively, the cover can be snap-fitted to the mounting slot 110, meaning that, based on the separation of the cover from the housing 100, structures such as slots or slide rails can be provided as installation limiting structures for the cover, thereby exposing or covering the opening 710 of the microphone storage compartment 700. This design facilitates the user's access to and placement of the microphone and effectively protects the microphone from dust, debris, and other contaminants when not in use.

[0042] In practical installation, the screen is preferably positioned on the side of the cover facing the mounting slot 110. This placement protects the screen when the cover is closed, preventing damage from external factors. The screen can be operated via touch or physical buttons, displaying information such as the speaker's operating status, volume adjustment, and audio input mode, further enhancing user convenience. Furthermore, the screen can integrate smart functions, such as Bluetooth connection status display, battery monitoring, and audio device pairing information, providing intuitive operational feedback. To enhance screen durability, its surface can be waterproofed for improved reliability in outdoor use. A sealing strip can also be added at the connection between the cover and the mounting slot 110 to prevent rainwater or dust from entering the screen and microphone storage compartment 700.

[0043] In summary, the performance of the three-way portable speaker with screen of this invention is as follows: The three-way configuration of the tweeter 200, woofer 300, and passive radiator 400 in this portable three-way speaker with a screen allows the tweeter, woofer, and subwoofer to work independently yet complement each other, creating a layered and full sound effect. The symmetrical layout of the tweeter and woofer not only optimizes the sound field distribution but also effectively reduces distortion during sound propagation, ensuring users enjoy a clear and stable sound quality experience in various scenarios. The passive radiator 400 provides subwoofer assistance with lower production costs, enhancing the depth and power of the low-frequency response and adding a powerful bass effect to the music. Especially in outdoor environments, this design better adapts to complex sound propagation conditions, allowing users to experience a more immersive listening experience.

[0044] The application of the limiting tray 420 and the slide 410 structure in the assembly structure of the passive radiator 400 greatly improves the maintainability of the equipment. Users can quickly replace or repair the passive radiator 400 without professional tools, reducing later maintenance costs. Meanwhile, the three-way portable speaker with a screen also features auxiliary structures such as a screen mounted on the cover and a microphone storage compartment 700, meeting users' outdoor usage needs and enhancing the practicality and convenience of the three-way portable speaker with a screen.
