Technical Field
[0001] This invention belongs to the field of speaker technology, specifically relating to a speaker with a rotating shaft adjustable mid-high frequency sound unit. Background Technology
[0002] With the increasing demand for audio experience in outdoor parties, family gatherings and other scenarios, PartySpeaker, as an audio device that combines portability and high power output, is widely used in various leisure and entertainment scenarios. At present, traditional PartySpeakers have common features in their structural design, which usually concentrate the mid-high frequency sound units in a single cabinet, and the sound propagation exhibits point source radiation characteristics. However, due to the shorter wavelengths, weaker diffraction capabilities, and obvious directivity of mid-to-high frequency sound waves, this centralized layout directly results in a narrow sound field coverage and insufficient separation between the left and right channels. It is difficult to create a wide and three-dimensional surround sound field, which cannot meet the needs of listeners in different positions during a multi-person gathering for an immersive audio experience. Especially in outdoor open spaces, the limitations of sound propagation are more prominent. Listeners must be within the speaker's preset "optimal listening zone" to obtain an ideal sense of sound location and space. Once they deviate from this zone, the clarity and positioning accuracy of the sound will decrease significantly, and there may even be problems such as a fluctuating sound field and loss of detail. Summary of the Invention
[0003] The purpose of this invention is to provide a speaker with a rotating adjustable mid-high frequency sound unit. Through the cooperation of the rotating structure and the soundbar, the direction of mid-high frequency sound can be flexibly adjusted according to the listener's position and the size of the scene, so as to meet the best listening needs in different scenarios and solve the problems mentioned in the background art.

Detailed Implementation The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1 This invention provides, for example Figure 1-3The speaker shown is a rotating adjustable mid-high frequency speaker unit, comprising a speaker body 1, with soundbars 2 mounted on both sides of the speaker body 1. One end of each soundbar 2 is connected to a rotating structure 5, which is connected to the upper side wall of the speaker body 1. The rotating structure 5 can drive the soundbars 2 to flexibly adjust their sound emission positions on both sides of the speaker body 1. By integrating mid-high frequency sounds into the two soundbars 2 and flexibly adjusting their sound emission positions driven by the rotating structure 5, the point source sound emission is changed to dual-sided distributed sound emission, significantly widening the horizontal sound field coverage and meeting the listening needs of multiple people and multiple positions. Through the independent soundbars 2 on both sides, the sound channels are physically separated, improving the channel separation and creating an immersive surround sound field. The sound emission angle can be flexibly adjusted according to the listener's position and the size of the scene, maintaining clear sound quality and stable sound field positioning throughout the entire area. In addition, the dual-sided adjustable structure of this solution enhances the horizontal diffusion and vertical projection of sound, making it suitable for use in large outdoor spaces. The rotating structure 5 includes a rotating shaft. The speaker body 1 has mounting slots 4 on both sides for folding and storing the soundbar 2. The rotating shaft is inserted and fixed to one end of the soundbar 2. The two ends of the rotating shaft are rotatably connected to the side wall of the mounting slot 4 through damping bearings, and the rotating shaft is located at the upper end of the mounting slot 4. The damping bearings provide stable rotational resistance, allowing the soundbar 2 to stay at any angle. The mounting slot 4 allows for concealed storage when not in use, keeping the speaker's overall design simple and not taking up extra space. The rotation adjustment is precise, and the mid-high frequency sound angle can be slightly adjusted to suit close-range, small-scene listening. A pull rod 3 is inserted into the speaker body 1. The direction of the mounting groove 4 is parallel to the pulling direction of the pull rod 3. When not in use, the bar speaker 2 is completely located in the mounting groove 4. After storage, the speaker body is a neat bar shape. There are no protrusions or bumps when the pull rod 3 is dragged, making it easier to move. The parallel layout makes the sound direction consistent with the user's orientation after unfolding, resulting in a more natural listening position and a clearer sound field. The pull rod 3 can also be replaced by a handle. When a handle is used, it can be directly fixed to the upper end of the speaker body 1, making it convenient to pull the speaker body 1 by the pull rod 3 or the handle. Example 2 The similarities will not be repeated here. The difference from Example 1 is that, as... Figure 4-6As shown, the soundbar 2 includes a second speaker 22 and a first speaker 21 located in the mounting slot 4. The first speaker 21 and the second speaker 22 are rotatably connected by a connecting shaft, allowing the first speaker 21 and the second speaker 22 to be rotated 90 degrees. The outer wall of the speaker body 1 has a storage slot 6 for storing the first speaker 21 and the second speaker 22. The soundbar 2 is set as a double-section folding structure of the first speaker 21 and the second speaker 22. When unfolded, the channel spacing is larger, the separation is further improved, and the vertical layout widens the horizontal sound field, which is suitable for large spaces and multi-person surround sound listening. When folded, the volume is small and does not increase the carrying size, which takes into account both the large sound field and portability. Example 3 The similarities will not be repeated here. The difference from Example 1 is that, as... Figure 7-9 As shown, the rotating shaft structure 5 includes a universal ball seat 51 with damping effect. The mounting end of the universal ball seat 51 is fixed to the upper ends of both sides of the speaker body 1. One end of the soundbar 2 is fixed to the rotating end of the universal ball seat 51. Breaking the limitation of single-axis rotation, the soundbar 2 can be adjusted 360 degrees in all directions and emit sound at any angle, horizontally, vertically, or obliquely. The damping positioning is stable, suitable for irregular venues and listeners from multiple directions, and the sound field coverage is without dead angles. Example 4 The similarities will not be repeated here. The difference from Example 1 is that, as... Figure 10-13 As shown, the rotating shaft mechanism includes a bracket 52. One end of the bracket 52 is rotatably connected to the side wall of the speaker body 1 via a hinge shaft 53. Both sides of the other end of the bracket 52 are fixed with hinge seats for hinged with the soundbar 2. The double hinge structure forms a double rotation adjustment. The bracket 52 can be flipped as a whole, and the soundbar 2 can rotate on its own, providing more adjustment dimensions. The mid-high frequency sound unit can be extended outwards significantly, maximizing the channel spacing and achieving optimal sound field width and surround sound. The speaker body 1 has a groove 7 on its side wall for mounting the bracket 52. The hinge shaft 53 is rotatably mounted on the lower end of the groove 7 via a damping bearing. The bracket 52 can rotate within a 180° range around the hinge shaft 53. A latch is provided between the bracket 52 and the speaker body 1 to limit the position of the bracket 52. The 180-degree rotation allows the soundbar 2 to be adjusted to emit sound from the front, side, or back. The latch is mounted on the bracket 52. The speaker body 1 has multiple slots that engage with the latch. The engagement of the multiple slots with the latch limits the position of the rotated bracket 52, ensuring the stability of the soundbar 2 supported on the bracket. The groove 7 allows the bracket 52 to be completely embedded, resulting in a flat appearance after storage with no protruding structures, making it safer to move and store. The bracket 52 has a H-shaped structure, and the shape of the groove 7 is matched with the shape of the bracket 52. The H-shaped bracket 52 is lightweight, strong, and provides stable support without wobbling. The matching groove 7 makes storage more compact and improves the overall durability and aesthetics of the speaker. The bracket 52 can also be other structures, such as a U-shaped structure, depending on its stability requirements, to support the bar speaker 2. The bracket 52 can also be used to pull the speaker body 1, making it easy to move the speaker body 1. One end of the soundbar 2 is integrally formed with a protruding post, and one end of the protruding post is rotatably connected to the hinge seat through a damping bearing. The integrally formed protruding post structure is sturdy and not easily damaged. The damping rotation allows the soundbar 2 to be independently finely adjusted at a small angle. In conjunction with the rotating bracket 52, it can achieve a combination of coarse and fine adjustment, resulting in more accurate sound field positioning. The length of the bracket 52 is greater than the length of the soundbar 2. The soundbar 2 is on the outer wall of the bracket 52, and the soundbar 2 is rotated 90 degrees around the convex pillar as the axis, extending the soundbar 2 out of the sides of the speaker body 1. After extension, the soundbar 2 is away from the main body, maximizing the physical distance between the left and right channels and achieving peak channel separation. The 90-degree rotation allows for quick unfolding, simple operation, and instant realization of a wide surround sound field, making it suitable for outdoor parties and large gatherings. By splitting the mid-high frequency unit originally concentrated inside the speaker body 1 and integrating it into the soundbar 2 on both sides of the speaker body 1, independent dual-sided sound units are formed, replacing the traditional single-point concentrated sound. The soundbar 2 can be rotated, flipped, folded, extended, and positioned at multiple angles through the hinge structure 5. Users can adjust it by hand without tools, and freely adjust the unfolding angle, outward extension distance, and sound direction of the soundbar 2 according to the size of the venue, the position of the audience, and the usage scenario. The horizontal diffusion width and vertical projection depth of the sound can be manually controlled, so that the sound can be transformed from a point to a surface, covering the entire area. When not in use, the soundbar 2 can be stored through the hinge structure 5, flush with the speaker body 1, and the pull rod 3 can be used to maintain the size and mobility of the portable speaker. It should be noted that the soundbar is a soundbar speaker, and the cables connecting the soundbar speaker and the main body 1 of the soundbar are all concealed. The hinge mechanism is equipped with a cable routing cavity to facilitate cable routing, while not affecting the position adjustment of the soundbar speaker, thus increasing the overall aesthetics of the soundbar. Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
