Description
Technical Field
[0001] This utility model relates to the field of audio sound guiding structure, and in particular to an audio system with a high-power sound guiding structure. Background Technology
[0002] In many cases, when speaker design is based on aesthetics or intelligent voice settings, and the speaker cannot directly radiate sound, it needs to change the direction of sound radiation through reflection. The sound reflection capability varies greatly depending on the frequency, and it is impossible to completely reflect and emit sound of all frequencies.
[0003] Based on the functional requirements of audio products, it is necessary to study and design the sound output structure of audio products, taking into account the sound transmission principle, the appearance of the audio equipment in practical applications, and the sound playback and pickup distance requirements of intelligent voice systems. Summary of the Invention
[0004] Existing audio products cannot directly radiate sound, nor can they completely reflect and emit sound at all frequencies.
[0005] To address the aforementioned issues, a high-power sound guide structure is proposed. By placing a sound guide structure on the outside of the speaker assembly, and utilizing protrusions on the sound guide structure to compress the sound from the speaker, the sound velocity is increased, reducing losses caused by airflow convection between the sound and the sound guide structure. The sound guide grooves on the sound guide structure radiate the compressed sound to the output area, further enhancing the sound velocity and improving the sound effect. By designing the two guide walls of the sound guide groove into a regular wave-like fan shape, the sound emitted from the central area is further guided, minimizing mutual interference and ensuring that all frequencies of the emitted sound do not superimpose or cancel each other out. This solves the problem in existing speaker products where the speaker cannot directly radiate sound or completely reflect all frequencies of sound.
[0006] In a first aspect, a speaker with a high-power sound-conducting structure includes:
[0007] Speaker assembly;
[0008] Sound guiding structure;

[0012] Boss and multiple sound guide slots;
[0013] The boss is located at the center of the base housing and close to the speaker, and is used to compress the sound output from the speaker;
[0014] The plurality of sound guide grooves radiate outward from the boss to radiate the extruded sound to the sound outlet of the housing.
[0015] In a first possible embodiment of the speaker with a high-power sound-conducting structure described in this utility model, the sound-conducting structure further includes:
[0016] Base shell;
[0017] The boss is located at the center of the base housing, and the plurality of sound guide grooves extend radially outward from the boss.
[0018] In conjunction with the first possible embodiment of this utility model, in the second possible embodiment, the boss includes:
[0019] Multiple slopes;
[0020] The plurality of ramps slope outwards from the center of the boss.
[0021] In conjunction with the first possible embodiment of this utility model, in the second possible embodiment, the sound guide groove includes:
[0022] First sound guide wall and second sound guide wall;
[0023] One end of the first sound guide wall and the second sound guide wall are obliquely connected to the ramp, and the other end of the first sound guide wall and the second sound guide wall extend outward to facilitate sound transmission.
[0024] In conjunction with the second possible embodiment of this utility model, and in the third possible embodiment, the speaker assembly includes:
[0025] Fixture;
[0026] speaker;
[0027] The mounting bracket has a fixing hole at its center, and the speaker is fixed in the fixing hole.
[0028] In conjunction with the third possible embodiment of this utility model, and in the fourth possible embodiment, the fixing frame further includes:
[0029] Sound-conducting surface;
[0030] The sound guide surface is curved and forms a recess with the speaker; the protrusion extends forward into the recess to compress the sound emitted by the speaker.
[0031] In conjunction with the fifth and sixth possible embodiments of this utility model, the cross-section of the speaker assembly, the sound guiding structure, and the housing is circular.
[0032] In conjunction with the sixth and seventh possible embodiments of this utility model, the boss is circular and is located at the center of the sound guiding structure, and the first and second sound guiding walls extend outward from the boss.
[0033] In conjunction with the seventh and eighth possible embodiments of this utility model, the first sound guide wall and the second sound guide wall are in the shape of regular wave-shaped fan blades.
[0034] In a ninth possible embodiment of the speaker with a high-power sound-conducting structure described in this utility model, the housing includes:
[0035] Multiple sound output zones;
[0036] Each of the aforementioned sound output areas has multiple sound output holes arranged in it.
[0037] The high-power sound guide structure described in this invention solves the problem of existing audio products where the speaker cannot directly radiate sound or completely reflect all frequencies of sound. This is achieved by setting a sound guide structure on the outside of the speaker assembly and using protrusions on the sound guide structure to compress the sound from the speaker, increasing the sound velocity and reducing losses caused by airflow convection between the sound and the sound guide structure. The sound guide grooves on the sound guide structure radiate the compressed sound to the output area, further enhancing the sound velocity and sound effect. Furthermore, by designing the two guide walls of the sound guide grooves into regular wavy fan-shaped shapes, the sound emitted from the central area is further guided, minimizing mutual interference and ensuring that all frequencies of the emitted sound do not superimpose or cancel each other out.

[0049] Existing audio products, such as the 120-speaker, cannot directly radiate sound, nor can they completely reflect and emit sound at all frequencies.
[0050] To address the above problems, a speaker with a high-power sound guiding structure 300 is proposed.
[0051] Firstly, a speaker with a high-power sound-conducting structure 300, such as... Figure 1 , Figure 1 This is a first exploded view of an audio device with a high-power sound guiding structure 300 according to the present invention; it includes a speaker assembly 100, a sound guiding structure 300, and a housing; the speaker assembly 100 and the sound guiding structure 300 are fixedly disposed inside the housing; the sound guiding structure 300 is fixedly disposed on the outside of the speaker assembly 100, including a boss 320 and a plurality of sound guiding grooves 310; the boss 320 is disposed at the center of the base housing and close to the speaker 120, and is used to compress the sound output from the speaker 120; the plurality of sound guiding grooves 310 radiate from the boss 320 to the surrounding area, and are used to radiate the compressed sound output to the sound outlet of the housing.
[0052] In this embodiment, the speaker assembly 100 is fixed in the housing by bolts, and the sound guiding structure 300 is fixedly connected to the housing by clips or bolts.
[0053] In one application scenario of this embodiment, the speaker 120 of the audio system cannot directly radiate sound and needs to conduct the sound.
[0054] In this embodiment, the sound guiding structure 300 is positioned directly opposite the speaker 120 of the speaker assembly 100, compressing and conducting the sound emitted by the speaker 120. By providing the sound guiding structure 300 on the outside of the speaker assembly 100, and by utilizing the protrusions 320 on the sound guiding structure 300 to compress the sound from the speaker 120, the sound velocity is increased, and the loss caused by airflow convection between the sound and the sound guiding structure 300 is reduced. This solves the problem in existing audio products where the speaker 120 cannot directly radiate sound or completely reflect and emit sound of all frequencies.
[0055] In some alternative implementations, such as Figure 3 , Figure 3This is a schematic diagram of the sound guiding structure 300 of an audio device with a high-power sound guiding structure 300 according to the present invention. The sound guiding structure 300 also includes a base housing; a boss 320 is disposed at the center of the base housing, and a plurality of sound guiding grooves 310 extend radially from the boss 320 to the surrounding area.
[0056] In one application scenario of this embodiment, the boss 320 is integrally injection molded at the center of the base housing, and the sound guide groove 310 is also integrally injection molded on the base housing.
[0057] The sound guide groove 310 gradually expands outward from the boss 320 in order to conduct sound.
[0058] In this application scenario, the sound emitted by the speaker 120 is squeezed by the boss 320 and enters each sound guide groove 310, and is conducted and radiated outward through the sound guide groove 310.
[0059] In some alternative embodiments, the boss 320 includes a plurality of ramps 321; the plurality of ramps 321 slope outward from the center of the boss 320.
[0060] In one application scenario of this embodiment, during injection molding, the boss 320 gradually shrinks upward from the base shell to form a ramp 321 that surrounds the perimeter, and this ramp 321 is divided by the sound guide groove 310.
[0061] In this application scenario, by adopting the ramp 321 design, sound can enter the sound guide groove 310 better, improving the conduction effect.
[0062] In some alternative embodiments, the sound guide groove 310 includes a first sound guide wall 311 and a second sound guide wall 312; one end of the first sound guide wall 311 and the second sound guide wall 312 is obliquely connected to the ramp 321, and the other end of the first sound guide wall 311 and the second sound guide wall 312 extends outward to facilitate sound transmission.
[0063] In one application scenario of this embodiment, the sound guide groove 310 is surrounded by a first sound guide wall 311 and a second sound guide wall 312, and opens at the end of the sound guide groove 310 to conduct sound to the sound output area 210.
[0064] In this application scenario, the sound guide 310 is an expanded type to allow sound to radiate.
[0065] In some alternative implementations, such as Figure 2 , Figure 2 This is a second exploded view of an audio system with a high-power sound guiding structure 300 according to the present invention; the speaker assembly 100 includes a mounting bracket 110 and a speaker 120; a mounting hole 111 is provided in the center of the mounting bracket 110, and the speaker 120 is fixed in the mounting hole 111.
[0066] In one application scenario of this embodiment, the mounting bracket 110 further includes a sound guiding surface 112; the sound guiding surface 112 is curved and forms a recess 101 with the speaker 120.
[0067] In this application scenario, the sound guide surface 112 is curved and contacts each sound guide groove 310. The recess 101 facilitates the forward extension of the boss 320 to compress the sound. The boss 320 extends forward into the recess 101 to compress the sound emitted by the speaker 120.
[0068] In some alternative embodiments, the speaker assembly 100, the sound guiding structure 300, and the housing have a circular cross-section.
[0069] In this application scenario, the housing is circular, meaning the product as a whole is cylindrical.
[0070] Furthermore, in the application scenario of this embodiment, the speaker 120 is circular, the mounting bracket 110 that fixes the speaker 120 is also circular, and thus the speaker assembly 100 is also circular.
[0071] Furthermore, in the application scenario of this embodiment, the sound guiding result is adapted to the structure of the housing and speaker assembly 100, and is also circular.
[0072] In this application scenario, the boss 320 is integrated with the sound guiding structure 300. The boss 320 is circular and is located at the center of the sound guiding structure 300. The first sound guiding wall 311 and the second sound guiding wall 312 extend outward from the boss 320.
[0073] In this application scenario, the first sound guide wall 311 and the second sound guide wall 312 are in the shape of regular wave fan blades. By utilizing the sound guide groove 310 on the sound guide structure 300 to radiate the compressed sound to the sound output area 210, and by designing the two sound guide walls of the sound guide groove 310 into a regular wave fan blade shape, the sound emitted from the compressed central area is further guided, minimizing mutual interference and ensuring that all frequencies of the emitted sound do not superimpose or cancel each other out as much as possible.
[0074] In this application scenario, the housing includes multiple sound outlet areas 210; each sound outlet area 210 has multiple sound outlet holes arranged in it.
[0075] The audio system with a high-power sound guiding structure 300 of this invention increases the sound velocity and reduces the loss caused by airflow convection between the sound and the sound guiding structure 300 by using the protrusions 320 on the sound guiding structure 300 to compress the sound of the speaker 120. Furthermore, the sound velocity is increased and the sound effect is enhanced by using the sound guiding grooves 310 on the sound guiding structure 300 to radiate the compressed sound to the sound output area 210.
[0076] By designing the two sound guide walls of the sound guide groove 310 into a regular wave fan shape, the sound squeezed and emitted from the central area is guided again, minimizing mutual interference and ensuring that all frequencies of the emitted sound do not overlap or cancel each other out. This solves the problem in existing audio products where the speaker 120 cannot directly radiate sound or completely reflect and emit sound of all frequencies.
[0077] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
