Description

A multi-head tweeter assembly Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a multi-head tweeter assembly. Background Technology

[0002] In the field of loudspeaker technology, traditional tweeters typically employ a single-head design. This design has significant limitations; the tweeter can only emit sound waves in a single direction, resulting in a limited sound coverage. When listeners are positioned away from directly in front of the speaker, the brightness and detail of the high frequencies rapidly diminish, and the sense of stereo and spatial depth decreases, failing to meet the high-quality high-frequency demands of all listeners in a large space.

[0003] Current technology has not yet effectively solved this problem, and the propagation method of traditional single-head tweeters is incompatible with the development trend of modern audio technology. Therefore, an innovative design that can break through the limitations of traditional tweeter propagation methods is needed to improve the overall performance of audio systems and user experience. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-head tweeter assembly to overcome the shortcomings of traditional single-head tweeters that can only emit sound in one direction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-head tweeter assembly, comprising:

[0007] A bracket, wherein two or more tweeters are provided at the upper end of the bracket, and each tweeter contains a sound-producing element;

[0008] The tweeter is arranged in a geometric shape and has different tilt angles;

[0009] The tweeter is equipped with a guide, which is movably installed inside the tweeter via a fixed cover.

[0010] The upper cross-sectional dimension of the fixed cover is smaller than the lower cross-sectional dimension, and the cross-sectional dimension of the guide is smaller than the lower cross-sectional dimension of the fixed cover but larger than the upper cross-sectional dimension of the fixed cover.

[0011] The inside of the fixed cover is a smooth arc surface that allows the guide to move.

[0012] The outer side of the guide is a smooth arc surface that mates with the inner side of the fixed cover.

[0013] The tweeter and the inner cross-section of the mounting cover are circular.

[0014] The tweeter is connected to the fixed cover via threads.

[0015] The bracket has internal channels that allow cables to pass through.

[0016] A cable management plate is provided at the connection between the bracket and the tweeter.

[0017] The guide is equipped with guide vanes.

[0018] The guide vanes are arranged radially.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] This invention proposes a multi-head tweeter assembly. By mounting two or more tweeters on the upper part of a support, each tweeter contains a sound-emitting element, allowing sound to be emitted from multiple point sources. The tweeters are arranged in a geometric shape with different tilt angles. This arrangement directs sound in different directions, thus widening the sound field coverage and ensuring that listeners in different positions can enjoy clear and bright high-frequency effects. Furthermore, a guide is provided on each tweeter, which is movably mounted inside the tweeter via a fixed cover. Users can adjust the angle of the guide according to actual acoustic needs, further precisely controlling the direction of sound output. This multi-head tweeter assembly design not only directs sound in multiple directions but also allows for more flexible sound propagation through guide adjustment, effectively overcoming the limitations of traditional single-head tweeters in terms of sound coverage.

[0026] In the field of loudspeaker technology, traditional tweeters typically employ a single-head design. This design has significant limitations; the tweeter can only emit sound waves in a single direction, resulting in a limited sound coverage. When listeners are positioned away from directly in front of the speaker, the brightness and detail of the high frequencies rapidly diminish, and the sense of stereo and spatial depth decreases, failing to meet the high-quality high-frequency demands of all listeners in a large space.

[0027] Current technology has not yet effectively solved this problem, and the propagation method of traditional single-head tweeters is incompatible with the development trend of modern audio technology. Therefore, an innovative design that can break through the limitations of traditional tweeter propagation methods is needed to improve the overall performance of audio systems and user experience.

[0028] Based on this, this utility model proposes a multi-head tweeter assembly, aiming to overcome the limitations of traditional single-head tweeters through innovative design, achieving optimized sound field coverage and superior acoustic performance. This assembly is particularly suitable for scenarios requiring sound to propagate in multiple directions, ensuring a superior audio experience for listeners in multiple directions.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0033] Referring to Figures 1 to 4, a specific embodiment of the multi-head tweeter assembly provided by this utility model is shown, including:

[0034] The bracket 1 has two or more tweeters 2 at its upper end, and each tweeter contains a sound-producing element 7.

[0035] The tweeter 2 has a geometric layout and different tilt angles;

[0036] A guide 3 is provided on the tweeter 2, and the guide 3 is movably installed inside the tweeter through a fixing cover 4.

[0037] Traditional single-head tweeters can only emit sound in one direction, resulting in limited sound coverage. When the listener is not directly in front of the speaker, the brightness and detail of the high frequencies decrease rapidly. To overcome this problem, this component has two or more tweeters 2 arranged in a geometric pattern on the upper part of the bracket 1. This arrangement directs sound in different directions, greatly widening the sound field coverage. This allows listeners to enjoy clear and bright high frequencies from different positions, effectively enhancing the stereo and spatial effects of the audio system.

[0038] Specifically, the geometric layout of the tweeter 2 can take many forms, such as a circular layout, where the tweeters 2 are evenly distributed around the upper circumference of the support 1 to form a circular array, which can achieve 360-degree sound wave diffusion; a square layout, where the tweeters 2 are arranged in a square grid to form a square array, which is suitable for rectangular spaces and can enhance the lateral and longitudinal coverage of the sound field; and a triangular layout, where the tweeters 2 are distributed in an equilateral triangular grid to form a triangular array, which can optimize the diffusion of sound waves and make the sound more evenly distributed in space.

[0039] The tweeter 2 is positioned at a specific angle with the bracket 1. This design not only optimizes acoustic performance but also considers the overall size of the component and its compatibility with other parts. Through this clever angle design, the tweeter 2 can better adapt to limited spaces, reducing interference with the housing or other components. This allows the component to maintain high performance while easily integrating into various audio systems. Different tilt angles can guide sound waves in specific directions, further optimizing the uniformity and stereo effect of the sound field.

[0040] The guide 3 is movably mounted inside the tweeter 2 via the fixed cover 4, as shown in Figure 3. Users can adjust the angle of the guide 3 by pressing it manually according to actual acoustic needs, thereby further precisely controlling the direction of sound output. This adjustable design provides users with greater flexibility, allowing the audio system to better adapt to different usage scenarios and listener positions. In this specific embodiment, it is preferable that the upper cross-sectional dimension of the fixed cover 4 is smaller than its lower cross-sectional dimension, and the cross-sectional dimension of the guide 3 is smaller than the lower cross-sectional dimension of the fixed cover but larger than the upper cross-sectional dimension of the fixed cover. The inner side of the fixed cover 4 is a smooth arc surface that allows the guide 3 to move, and the outer side of the guide 3 is a smooth arc surface that mates with the inner side of the fixed cover 4, making the angle adjustment of the guide 3 smoother.

[0041] The bracket 1 has internal channels that allow cables to pass through. This design effectively organizes cables, preventing them from becoming tangled and reducing electromagnetic interference, thus improving the quality of audio signal transmission. A cable management plate 5 is located at the connection between the bracket 1 and the tweeter 2, further securing and organizing the cables, ensuring they are neatly arranged inside the bracket 1 for easy installation and maintenance. The tweeter 2 and the mounting cover 4 have a circular inner cross-section. The tweeter 2 is connected to the mounting cover 4 via threads. This connection method provides high strength and stability, capable of withstanding significant sound pressure changes, ensuring the tweeter 2 will not loosen during operation. The threaded connection also facilitates installation and disassembly, making it convenient to maintain or replace the tweeter 2.

[0042] The guide vane 3 is equipped with guide vanes 6, which are arranged radially. This distribution allows sound waves to diffuse uniformly in all directions, enhancing the uniformity and three-dimensionality of the sound field. The guide vanes 6 can be made of plastic, metal, or composite materials. Different materials have different acoustic properties and structural strengths, and can be selected according to specific application scenarios. At the same time, the thickness and surface treatment of the guide vanes 6 are also optimized to reduce sound wave reflection and interference, and improve the transmission efficiency and quality of sound waves.

[0043] To make the multi-head tweeter assembly provided by this utility model easier to understand, a more intuitive specific implementation method is also provided.

[0044] In an office environment, space is relatively limited and people are concentrated in one area. Therefore, this component uses two tweeters 2, symmetrically arranged around the support 1, facing opposite sides of the desk. This layout ensures that people sitting on either side of the desk can enjoy a clear and bright high-frequency experience. The tweeters 2 are circular, with a simple and aesthetically pleasing design that blends easily into various office environments, while also promoting even sound wave diffusion.

[0045] The tweeter 2 is mounted in the center of the speaker, with the woofer section below it. Because the woofer section vibrates during operation, a certain distance is maintained between the bottom of the tweeter and the woofer section to prevent this vibration from affecting the acoustic performance of the tweeter. The bracket 1 is cylindrical, extending to connect to the tweeter 2 at the top. This design not only provides stable support but also effectively utilizes space, reducing the overall size of the components. The bracket 1 has internal channels for cable passage, allowing for neat and orderly cable routing. This not only facilitates installation and maintenance but also reduces electromagnetic interference and improves the transmission quality of audio signals.

[0046] Each tweeter 2 is equipped with a guide vane 3. The guide vane 3 is movably mounted inside the tweeter 2 via a fixing cover 4, and the user can manually adjust the angle of the guide vane 3 as needed to further optimize the direction of sound propagation. This adjustable design allows the sound system to better adapt to different office environments and personnel positions, providing greater flexibility.

[0047] The tweeter 2 and the inner cross-section of the fixing cover 4 are circular. The tweeter 2 is connected to the fixing cover 4 by threads. This connection method not only ensures the stability of the tweeter 2, but also withstands certain sound pressure changes, ensuring that the tweeter 2 will not loosen during operation. At the same time, it is easy to install and disassemble, which is beneficial for subsequent maintenance or replacement.

[0048] The guide vane 3 is equipped with guide vanes 6, which are arranged radially. This design allows sound waves to diffuse evenly in all directions, enhancing the uniformity and stereoscopic effect of the sound field. Both the guide vane 3 and the tweeter 2 are made of plastic. Plastic is not only lightweight and inexpensive, but also has good acoustic properties, effectively reducing sound wave reflection and interference during propagation, and improving sound wave transmission efficiency and quality.

[0049] In summary, this multi-head tweeter assembly, through the symmetrical arrangement of two tweeters 2 and the design of an adjustable guide 3, achieves multi-directional sound propagation in an office environment. The cylindrical bracket 1 and the rational structural layout not only ensure the stability of the assembly but also optimize acoustic performance. The choice of plastic material allows the assembly to maintain high performance while also offering good economy and practicality. This design is particularly suitable for applications in offices and other scenarios requiring multi-directional sound coverage.

[0050] The multi-head tweeter assembly provided by this utility model optimizes the sound field through the geometric layout of multiple tweeters 2 and the design of adjustable guides 3. Multidirectional sound wave propagation and precise guide adjustment ensure that listeners can enjoy high-quality high-frequency effects from different positions. This assembly can provide excellent stereo and spatial sound in various situations, greatly enhancing the user's listening experience.

[0051] The tilt angle design of tweeter 2 allows this component to maintain high performance while effectively controlling its overall size and reducing interference with other components. This compact design enables easy integration into various audio systems, offering excellent versatility and compatibility.

[0052] The adjustable guide 3 and multiple geometric layout options allow this component to adapt to various acoustic scenarios and user needs, providing optimal acoustic performance in a variety of situations through flexible configuration. Users can adjust the angle of the guide 3 according to actual needs to further optimize the sound field performance.

[0053] The cable channel and cable management board 5 inside bracket 1 effectively organize cables, reduce electromagnetic interference, and improve the transmission quality of audio signals. This design not only enhances the reliability of the components but also facilitates installation and maintenance, providing users with a more convenient user experience.

[0054] In summary, this multi-head tweeter assembly, through its meticulously designed tweeter layout 2, adjustable guide 3, cable management scheme, and compact structure, achieves optimized sound field, structural stability, and excellent adaptability and flexibility. It provides users with a high-quality, reliable audio solution that meets the evolving needs of modern audio technology.
