Description

Technical Field

[0001] The utility model relates to a horn structure, in particular to a single-magnetic coaxial high-pitched horn. Background Art

[0002] In situations where sound needs to be transmitted over a large area or over long distances, such as outdoor performances and large conference halls, tweeter horns can provide clearer and louder sound effects. Currently, in order to radiate sound energy to a greater distance, a larger horn opening area is set. To maintain the compactness of the overall structure, the distance between the horn and the radiating surface of the cone is designed to be relatively small. Due to the small distance between the horn and the radiating surface of the cone, low-frequency sound waves may be obstructed when passing through this narrow area, resulting in insufficient low-frequency response and a thin or lacking sound power. Low-frequency sound waves may also produce unnecessary reflections and interference in the confined space, causing sound distortion and affecting sound quality. Utility Model Content

[0003] The purpose of the utility model is to provide a single-magnet coaxial tweeter horn, and the technical problem to be solved is how to improve the response effect of low-frequency sound waves.

[0004] The utility model is achieved through the following technical solutions:

[0005] A single-magnet coaxial tweeter horn includes a T-iron, wherein the T-iron includes a core and a base plate, wherein the core is disposed on the base plate and a magnetic steel and a washer are provided on the core outer shell;

[0006] The core column is provided with a first central hole;

[0007] The end surface of the washer away from the magnetic steel is connected to a sound basin, and the sound basin is provided with a second center hole, and the first center hole and the second center hole are connected;

[0008] A small horn is sleeved in the second center hole, and the small horn is provided with a third center hole;

[0009] The inner wall of the small horn is connected to the inner wall of the sound cone and the inner wall of the core column, and the inner wall of the small horn, the inner wall of the sound cone and the inner wall of the core column form a radiation surface after connection;

[0010] The axes of the above-mentioned T iron, magnet, washer, cone and horn coincide with each other.

[0011] The aforementioned T-iron (including the core and base), magnet, washer, cone, and horn are combined to form a sound-generating unit. The T-iron serves as the structural support and magnetic conductor, the magnet provides the magnetic field, and the washer and T-iron work together to affect the cone, converting sound. The cone and horn directly contribute to the radiation and propagation of sound. The horn connects the inner wall of the core and cone to form a single, larger horn, resolving the narrow gap between the cone's inner wall and the horn found in existing technologies. This improves the response of low-frequency sound waves.

[0012] Furthermore, the first central hole includes a first through hole and a second through hole that are connected;

[0013] The diameter of the second through hole is larger than that of the first through hole;

[0014] A small horn is sleeved in the second through hole.

[0015] The increase in the aperture of the above-mentioned second through hole reduces the acoustic impedance between the small horn and the core column compared to the first through hole; the reduction in acoustic impedance helps low-frequency sound waves to pass through the small horn more smoothly, reducing reflection and energy loss caused by impedance mismatch, which means that more low-frequency sound wave energy can be effectively radiated into the air, improving the response effect of low-frequency sound waves; because the small horn is arranged in the second through hole with a larger aperture, the entrance part of the small horn obtains a larger acoustic space, so that the small horn can more effectively collect and amplify sound waves in the low-frequency band, enhancing the radiation ability of low-frequency sound waves; the propagation and diffusion of low-frequency sound waves in the small horn will also be more uniform, further improving the response effect of low-frequency sound waves.

[0016] Furthermore, the diameter of the first through hole gradually increases from the bottom plate to the axial direction of the washer;

[0017] A portion of the inner side wall of the core column corresponding to the first through hole forms a first arc surface radiation area.

[0018] The gradual increase in the aperture of the above-mentioned first through hole provides a gradually expanding propagation space for sound waves from the bottom plate to the washer, which helps to reduce the obstruction and reflection of the sound waves during the propagation process, so that the sound waves can pass through the core column more smoothly and propagate to the small horn and the sound cone; for low-frequency sound waves with longer wavelengths, they are more easily affected by obstacles in the propagation path, so this structure improves the response effect of low-frequency sound waves; due to the gradual increase in the aperture of the first through hole and the existence of the first curved surface radiation area, the obstruction and reflection encountered by the sound waves during the propagation process are greatly reduced, which means that more sound wave energy can be effectively transmitted to the sound cone and the small horn, and finally radiated into the air, reducing the loss of sound wave energy during the propagation process.

[0019] Furthermore, the second central hole includes a third through hole and a fourth through hole that are connected in sequence;

[0020] The diameter of the fourth through hole is larger than that of the third through hole;

[0021] The small horn is sleeved in the second through hole and the third through hole.

[0022] By arranging a multi-stage aperture (i.e., the third through hole and the fourth through hole) in the above-mentioned second center hole, the second through hole and the third through hole serve as the transition area between the small horn and the sound basin, and their gradually increasing aperture design helps to reduce the impedance change of the sound wave during the propagation process, so that the low-frequency sound waves can enter the small horn more smoothly, and the fourth through hole serves as a further expansion space inside the small horn, which helps to enhance the radiation effect of the low-frequency sound waves; the multi-stage aperture design not only takes into account the gradual increase in aperture, but also further optimizes the propagation path of the low-frequency sound waves by arranging the small horn in different apertures; the small horn is a key component for sound wave radiation, and its entrance part obtains a smoother transition and a larger acoustic space, which helps to reduce the reflection and diffraction of sound waves at the entrance of the small horn, so that the low-frequency sound waves can be radiated into the air more concentratedly.

[0023] Furthermore, the diameter of the fourth through hole gradually increases from the washer to the axial direction of the sound basin;

[0024] The portion of the inner side wall of the sound basin corresponding to the fourth through hole forms a second arc surface radiation area.

[0025] The gradual increase in the aperture of the above-mentioned fourth through hole, from the washer to the sound basin, provides a smoother and gradually expanding propagation space for low-frequency sound waves, further reducing the obstruction and reflection of the sound waves during the propagation process, so that the low-frequency sound waves can be more efficiently transmitted to the sound basin and stimulate the vibration of the sound basin; due to the gradual increase in the aperture of the fourth through hole and the existence of the second curved radiation area, the distortion of the low-frequency sound waves during the propagation and radiation process is greatly reduced. The gradual increase in the aperture reduces the mutation and reflection of the sound wave in the propagation path, and the curved radiation area helps to radiate the sound wave energy into the air more concentratedly, reducing the occurrence of low-frequency distortion, and making the low-frequency sound waves purer and clearer.

[0026] Furthermore, the diameter of the third central hole gradually increases from the washer to the axial direction of the sound basin;

[0027] The inner side wall of the small horn forms a third arc-surface radiation area.

[0028] The gradual increase in the aperture of the third central hole provides a smoother space for the propagation of low-frequency sound waves in the small horn. Low-frequency sound waves have a long wavelength and are easily obstructed and reflected during propagation. The gradual increase in the aperture can reduce these adverse effects, allowing low-frequency sound waves to pass through the small horn more efficiently and radiate into the air; the third arc radiation area formed on the inner wall of the small horn further enhances the radiation effect of low-frequency sound waves. The arc design helps to focus and guide the sound wave energy to a specific direction, thereby improving the directivity of low-frequency radiation; at the same time, the arc surface can also optimize the sound The diffusion of waves in the air allows low-frequency sound waves to cover a wider area, making the distribution of low-frequency sound waves in space more even, thereby enhancing the listener's auditory experience. Similar to the design of gradually increasing aperture and curved radiation area mentioned earlier, this optimization also helps to reduce low-frequency distortion. The gradual change in aperture reduces the sudden change of sound waves in the propagation path, while the curved radiation area helps to radiate the sound wave energy more concentratedly. The above-mentioned curved radiation areas work together to reduce the distortion of low-frequency sound waves during propagation and radiation, making the low-frequency sound waves purer and clearer.

[0029] Furthermore, the outer side wall of the small horn is in contact with the inner side wall portion of the core column corresponding to the second through hole and the inner side wall portion of the cone corresponding to the third through hole.

[0030] The outer wall of the small horn fits tightly against the inner wall of the core and the inner wall of the cone, enhancing the acoustic coupling between them. This coupling helps reduce the energy loss of sound waves during propagation, allowing low-frequency sound waves to pass through the small horn more efficiently and radiate into the air; at the same time, it also helps to reduce the reflection and diffraction of sound waves at the contact surface, improving the directionality and clarity of sound waves; through the fitting design, the sound wave propagation path between the small horn, core and cone is optimized, and the obstructions and interference encountered by the sound waves during propagation are greatly reduced, allowing the sound waves to pass through each component more smoothly and achieve the expected radiation effect.

[0031] Furthermore, the first arc surface radiation area and the second arc surface radiation area are smoothly connected;

[0032] The second arc surface radiation area and the third arc surface radiation area are smoothly connected;

[0033] The radiation surface is composed of a first arc radiation area, a second arc radiation area and a third arc radiation area.

[0034] Smoothly connected radiating surfaces help reduce reflection and diffraction of sound waves during the radiation process. When sound waves propagate from one curved surface radiation zone to another, if the connection is not smooth, the sound waves may produce a sudden change at the contact surface, resulting in sound energy loss and deterioration in sound quality. The smooth connection design ensures that the sound waves can propagate continuously and stably, improving the radiation efficiency and directionality of the sound waves. The continuous radiating surface composed of the first curved surface radiation zone, the second curved surface radiation zone and the third curved surface radiation zone provides a smoother and more stable propagation space for low-frequency sound waves, allowing low-frequency sound waves to more fully stimulate the vibration of the sound cone and radiate into the air, thereby improving the low-frequency response effect.

[0035] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0036] The aforementioned T-iron, magnet, washer, cone, and horn are combined to form a sound-generating unit. The T-iron supports and conducts magnets throughout the structure, while the magnet provides the magnetic field. The washer and T-iron work together to affect the cone, converting sound. The cone and horn are directly involved in radiating and propagating sound. The horn connects the inner wall of the core column to the inner wall of the cone, forming a large horn. This solves the problem of a narrow gap between the inner wall of the cone and the horn in existing technologies, thereby improving the response of low-frequency sound waves.

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0045] Example 1

[0046] This embodiment 1 provides a single magnetic coaxial tweeter horn, combined with Figures 1 to 4 , including a T iron 1, the T iron 1 includes a core column 11 and a bottom plate 12, the core column 11 is arranged on the bottom plate 12, and the core column 11 is provided with a magnetic steel 2 and a washer 5;

[0047] The core column 11 is provided with a first central hole 15;

[0048] The end surface of the washer 5 away from the magnetic steel 2 is connected to the sound cone 3, and the sound cone 3 is provided with a second center hole 33. The first center hole 15 and the second center hole 33 are connected;

[0049] The second center hole 33 is provided with a small horn 4, and the small horn 4 is provided with a third center hole 41;

[0050] The inner wall of the small horn 4 is connected to the inner wall of the cone 3 and the inner wall of the core 11. After the connection, the inner wall of the small horn 4, the inner wall of the cone 3 and the inner wall of the core 11 form a radiation surface;

[0051] The axes of the T iron 1, the magnet 2, the washer 5, the cone 3 and the horn 4 coincide with each other.

[0052] The T-iron 1, magnetic steel 2, washer 5, cone 3, and small horn 4 are combined to form a sound-generating unit. The T-iron 1 serves as the supporting and magnetic conductor for the entire structure, the magnetic steel 2 provides the magnetic field, and the washer 5 and the T-iron 1 act together on the cone 3 to achieve sound conversion. The cone 3 and small horn 4 directly participate in the radiation and propagation of sound. The small horn 4 connects the inner wall of the core 11 with the inner wall of the cone 3 to form a large horn, solving the problem of a narrow gap between the inner wall of the cone 3 and the horn in the prior art, thereby improving the response of low-frequency sound waves. Compared with a large horn, the use of a small horn 4 in this application also reduces material costs.

[0053] A bass driver can be installed outside the sound cone 3, and a tweeter driver can be connected to the end of the T-iron 1 away from the magnetic steel 2. The magnetic steel 2 provides a magnetic field, and the tweeter driver, T-iron 1, magnetic steel 2, washer 5, sound cone 3 and bass driver are all located on the same axis, which helps to reduce the phase difference and make the high and low frequency sounds better integrated during the propagation process, thereby improving the response effect of the low frequency sound waves; the magnetic steel 2 works synergistically with the T-iron 1, and the strong magnetic field provided by the magnetic steel 2 can enhance the vibration efficiency of the sound cone 3, thereby improving the radiation ability of the low frequency sound waves; the T-iron 1 ensures the effective use of the magnetic field, reduces the waste of magnetic energy, and further improves the response effect of low-frequency sound waves; the close connection between the cone 3, the core 11 and the small horn 4 forms an effective radiation surface, which is conducive to the directional propagation and enhancement of low-frequency sound waves; by optimizing the coordination between the cone 3, the core 11 and the small horn 4 and removing the gap between the cone 3 and the small horn 4, the energy loss and phase distortion of the sound waves during propagation are reduced, thereby ensuring that the low-frequency sound waves can still maintain high fidelity and clarity when reaching the listener.

[0054] Example 2

[0055] On the basis of Example 1, combined Figure 2 , the first center hole 15 includes a first through hole 13 and a second through hole 14 that are connected;

[0056] The diameter of the second through hole 14 is larger than that of the first through hole 13;

[0057] The second through hole 14 is sleeved with a small horn 4 .

[0058] The increase in the aperture of the above-mentioned second through hole 14 reduces the acoustic impedance between the small horn 4 and the core column 11 compared with the first through hole 13; the reduction in acoustic impedance helps low-frequency sound waves to pass through the small horn 4 more smoothly, reducing reflection and energy loss caused by impedance mismatch, which means that more low-frequency sound wave energy can be effectively radiated into the air, improving the response effect of low-frequency sound waves; since the small horn 4 is arranged in the second through hole 14 with a larger aperture, the entrance part of the small horn 4 obtains a larger acoustic space, so that the small horn 4 can more effectively collect and amplify sound waves in the low frequency band, enhancing the radiation ability of low-frequency sound waves; the propagation and diffusion of low-frequency sound waves in the small horn 4 will also be more uniform, further improving the response effect of low-frequency sound waves.

[0059] In the high frequency band, the main function of the small horn 4 is to improve the sound pressure level and directivity. In the low frequency band, the presence of the small horn 4 also helps to reduce the nonlinear distortion caused by the vibration of the cone 3. Since the small horn 4 is closely connected with the cone 3 and is connected to the core column 11 through the second through hole 14, this structure helps to transmit the vibration of the cone 3 to the small horn 4 more evenly, reducing the harmonic distortion and intermodulation distortion caused by uneven vibration; through the cooperation of the second through hole 14 and the small horn 4, while improving the low-frequency sound wave response effect, it also maintains the balance of the mid- and high-frequency sound waves, which helps to achieve a more natural and balanced sound performance, so that the low-frequency, mid-frequency and high-frequency sound waves can be harmoniously integrated, bringing a more realistic and immersive listening experience to the listener.

[0060] In a specific embodiment, the diameter of the first through hole 13 gradually increases from the bottom plate 12 to the axial direction of the washer 5 to increase the radiation surface.

[0061] The portion of the inner side wall of the core column 11 corresponding to the first through hole 13 forms a first arc surface radiation area.

[0062] The gradual increase in the aperture of the above-mentioned first through hole 13 provides a gradually expanding propagation space for sound waves from the bottom plate 12 to the washer 5, which helps to reduce the obstruction and reflection of the sound waves during the propagation process, so that the sound waves can pass through the core column 11 more smoothly and propagate to the small horn 4 and the sound cone 3; for low-frequency sound waves with longer wavelengths, they are more easily affected by obstacles in the propagation path, so this structure improves the response effect of low-frequency sound waves; due to the gradual increase in the aperture of the first through hole 13 and the existence of the first arc radiation area, the obstruction and reflection encountered by the sound waves during the propagation process are greatly reduced, which means that more sound wave energy can be effectively transmitted to the sound cone 3 and the small horn 4, and finally radiated into the air, reducing the loss of sound wave energy during the propagation process.

[0063] The formation of the above-mentioned first curved radiation zone enables the inner wall of the core column 11 to play a certain role as an acoustic lens during the propagation of sound waves. The curved surface design helps to focus and guide the sound waves into the sound cone 3 and the small horn 4, thereby enhancing the radiation efficiency of the sound waves. Under the guidance of the curved radiation zone, the sound waves can be radiated into the air more concentratedly, thereby improving the sound pressure level and directivity of the sound waves.

[0064] Example 3

[0065] Based on Example 2, combined Figure 3 , the second center hole 33 includes a third through hole 31 and a fourth through hole 32 that are connected in sequence;

[0066] The diameter of the fourth through hole 32 is larger than that of the third through hole 31;

[0067] The small horn 4 is sleeved in the second through hole 14 and the third through hole 31 .

[0068] By arranging a multi-stage aperture (i.e., the third through hole 31 and the fourth through hole 32) in the above-mentioned second center hole 33, the second through hole 14 and the third through hole 31 serve as the transition area between the small horn 4 and the sound basin 3. The gradually increasing aperture design helps to reduce the impedance change of the sound wave during the propagation process, so that the low-frequency sound waves can enter the small horn 4 more smoothly, and the fourth through hole 32 serves as a further expansion space inside the small horn 4, which helps to enhance the radiation effect of the low-frequency sound waves; the multi-stage aperture design not only takes into account the gradual increase in aperture, but also further optimizes the propagation path of the low-frequency sound waves by means of the small horn 4 being arranged in different apertures; the small horn 4 is a key component for sound wave radiation, and its entrance part obtains a smoother transition and a larger acoustic space, which helps to reduce the reflection and diffraction of sound waves at the entrance of the small horn 4, so that the low-frequency sound waves can be radiated into the air more concentratedly.

[0069] Since low-frequency sound waves have a long wavelength, they are easily affected by obstacles in the propagation path and cause distortion. The multi-stage aperture design and the installation of the small horn 4 can reduce the obstruction and reflection of the sound waves during the propagation process, thereby reducing the occurrence of low-frequency distortion.

[0070] In a specific embodiment, the diameter of the fourth through hole 32 gradually increases from the washer 5 to the axial direction of the sound cone 3, further expanding the radiation range;

[0071] The portion of the inner wall of the cone 3 corresponding to the fourth through hole 32 forms a second arc-surface radiation area.

[0072] The gradual increase in the aperture of the above-mentioned fourth through hole 32, from the washer 5 to the sound cone 3, provides a smoother and gradually expanding propagation space for low-frequency sound waves, further reducing the obstruction and reflection of the sound waves during the propagation process, so that the low-frequency sound waves can be more efficiently transmitted to the sound cone 3 and stimulate the vibration of the sound cone 3; due to the gradual increase in the aperture of the fourth through hole 32 and the existence of the second curved radiation area, the distortion of the low-frequency sound waves during the propagation and radiation process is greatly reduced, the gradual increase in the aperture reduces the mutation and reflection of the sound wave in the propagation path, and the curved radiation area helps to radiate the sound wave energy into the air more concentratedly, reducing the occurrence of low-frequency distortion, and making the low-frequency sound waves purer and clearer.

[0073] The formation of this second curved radiation zone enables the inner wall of the cone 3 to act as an important acoustic lens during the radiation of low-frequency sound waves. The curved surface design helps focus and guide low-frequency sound waves in a specific direction, thereby enhancing the directivity of low-frequency radiation. Furthermore, the curved surface design optimizes the distribution of sound waves on the surface of the cone 3, making the radiation of low-frequency sound waves more uniform and efficient, further improving the sound pressure level and coverage of low-frequency sound waves.

[0074] Example 4

[0075] Based on Example 3, combined Figure 4 , from the above-mentioned washer 5 to the axial direction of the sound cone 3, the aperture of the above-mentioned third center hole 41 gradually increases;

[0076] The inner side wall of the small horn 4 forms a third arc-surface radiation area.

[0077] The gradual increase in the aperture of the third center hole 41 provides a smoother space for the propagation of low-frequency sound waves in the small horn 4. The wavelength of low-frequency sound waves is long and they are easily obstructed and reflected during the propagation process. The gradual increase in the aperture can reduce these adverse effects, so that the low-frequency sound waves can pass through the small horn 4 more efficiently and radiate into the air; the third arc surface radiation area formed on the inner wall of the small horn 4 further enhances the radiation effect of the low-frequency sound waves. The arc surface design helps to focus and guide the sound wave energy to a specific direction, thereby improving the directivity of the low-frequency radiation; at the same time, the arc surface can also be optimized. It optimizes the diffusion of sound waves in the air, allowing low-frequency sound waves to cover a wider area and making the distribution of low-frequency sound waves in space more even, thereby enhancing the listener's auditory experience. Similar to the design of gradually increasing aperture and curved radiation area mentioned earlier, this optimization also helps to reduce low-frequency distortion. The gradual change of aperture reduces the sudden change of sound waves in the propagation path, while the curved radiation area helps to radiate the sound wave energy more concentratedly. The above-mentioned curved radiation areas work together to reduce the distortion of low-frequency sound waves in the process of propagation and radiation, making the low-frequency sound waves purer and clearer.

[0078] By optimizing the internal channel of small horn 4, the speaker can produce a higher sound pressure level at the same input power. By adjusting the design of small horn 4 and the curved radiation area, the low-frequency sound waves and the mid- and high-frequency sound waves are balanced in sound quality and volume, avoiding the situation where the low frequency is too strong and covers up the mid- and high-frequency sounds. This coordination enables the speaker to present a more natural and harmonious sound effect when playing various types of music.

[0079] Example 5

[0080] Based on Example 4, Figure 1The outer side wall of the small horn 4 is in contact with the inner side wall of the core column 11 corresponding to the second through hole 14 and the inner side wall of the cone 3 corresponding to the third through hole 31 .

[0081] The outer wall of the above-mentioned small horn 4 fits tightly against the inner wall of the core column 11 and the inner wall of the sound basin 3, which enhances the acoustic coupling between them. This coupling helps to reduce the energy loss of sound waves during propagation, so that low-frequency sound waves can pass through the small horn 4 more efficiently and radiate into the air; at the same time, it also helps to reduce the reflection and diffraction of sound waves at the contact surface, and improve the directionality and clarity of sound waves; through the fitting design, the sound wave propagation path between the small horn 4, the core column 11 and the sound basin 3 is optimized, and the obstacles and interference encountered by the sound waves during propagation are greatly reduced, so that the sound waves can pass through each component more smoothly and achieve the expected radiation effect; due to the close contact between the outer wall of the small horn 4 and the inner wall of the core column 11 and the sound basin 3, the low-frequency sound waves can obtain a stronger driving force and a more stable vibration environment during propagation, so that the vibration of the sound basin 3 in the low-frequency band is more sufficient and powerful, thereby improving the sound pressure level and sound quality of the low-frequency sound waves.

[0082] In a specific embodiment, the first arc surface radiation area and the second arc surface radiation area are smoothly connected;

[0083] The second arc surface radiation area and the third arc surface radiation area are smoothly connected;

[0084] The radiation surface is composed of a first arc radiation area, a second arc radiation area and a third arc radiation area.

[0085] The smoothly connected radiation surface helps reduce the reflection and diffraction of sound waves during the radiation process. When sound waves propagate from one curved radiation area to another, if the connection is not smooth, the sound waves may produce a sudden change at the contact surface, resulting in sound energy loss and deterioration in sound quality. The smooth connection design ensures that the sound waves can propagate continuously and stably, improving the radiation efficiency and directionality of the sound waves. The continuous radiation surface composed of the first curved radiation area, the second curved radiation area and the third curved radiation area provides a smoother and more stable propagation space for low-frequency sound waves, allowing low-frequency sound waves to more fully excite the vibration of the sound cone 3 and radiate into the air, thereby improving the low-frequency response effect.

[0086] The smoothly connected radiating surface also helps enhance the harmony of mid- and low-frequency sound waves. Because the three curved radiating areas are acoustically continuous and unified, they work together to influence the vibration of the cone 3, maintaining a balanced and harmonious sound quality and volume for mid- and low-frequency sound waves. The smooth connection also helps reduce distortion. When sound waves encounter uneven surfaces during radiation, they can generate additional vibration and noise, leading to distortion. The smoothly connected radiating surface reduces this additional vibration and noise, resulting in a purer and clearer sound wave.

It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model.
