[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In this embodiment of the invention, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this embodiment of the invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0022] Hereinafter, 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] Firstly, referring to Figure 1This utility model provides an angle-adjustable speaker, comprising: a tweeter module and a woofer module. The tweeter module includes at least two first tweeters and at least one second tweeter. The woofer module includes at least two woofers 100. At least one woofer 100 is disposed at a first end and a second end of the tweeter module. A first horn is disposed at the junction of the woofer 100 and the first tweeter. The first horn is located at the sound outlet of the first tweeter and is rotatably connected to the first tweeter. The second tweeter is disposed between the first tweeters. A second horn 300 is disposed at the sound outlet of the second tweeter and is detachably connected to the second tweeter.

[0024] Specifically, the first tweeter and the second tweeter 100 are placed close together. The second tweeter 100 generates bass signals, while the first and second tweeters generate treble signals, enabling the speaker to emit both bass and treble signals, thus improving sound quality and enhancing the user experience. Positioning the first and second tweeters in the middle of the speaker allows sound to travel further, while placing the tweeters 100 at both ends is more suitable for theater sound transmission, providing a better experience for audiences in all positions. Furthermore, placing the tweeters 100 at both ends better conforms to audio transmission and prevents treble interference; conversely, placing them in the middle makes them susceptible to interference from the high-voltage speakers at both ends, leading to severe bass signal attenuation or even loss of sound. This application incorporates a first horn between the first tweeter and the second tweeter 100 to guide the treble signal from the first tweeter, thereby reducing interference from the treble signal to the bass signal of the second tweeter 100. In different situations, the first horn can be freely rotated within a preset angle to change the transmission direction of the high-frequency signal from the first tweeter, making it highly adaptable, eliminating the need for reinstallation and angle determination, and ensuring high angle adjustment efficiency. Similarly, the second tweeter, positioned in the middle, focuses and guides the high-frequency signal through the second horn 300. By removing or installing second horns 300 with different guides, the transmission direction of the high-frequency signal from the second tweeter can also be changed. Overall, angle adjustment is convenient and cost-effective.

[0025] In some alternative embodiments, the subwoofer 100 includes a woofer 130 and a rotating assembly for rotating the woofer 130.

[0026] Specifically, the woofer 130 can be rotated by the rotating component, so that the bass signal of the woofer 130 can be transmitted within a preset directional range. Therefore, the transmission direction of the bass signal can be adjusted according to specific needs, making it highly adaptable. Moreover, the angle can be automatically adjusted by controlling the rotating component, which is convenient and has low adjustment cost.

[0027] In some alternative embodiments, the rotating assembly includes a first gear 120, a second gear 110, and a stepper motor. The first gear 120 is fixedly connected to a first end of the subwoofer 130, and the second end of the subwoofer 130 is configured as a bass output port. The second gear 110 meshes with the first gear 120, and the stepper motor is used to rotate the second gear 110.

[0028] Specifically, the first gear 120 is fixedly connected to the first end of the subwoofer 130, so that rotating the first gear 120 synchronously rotates the subwoofer 130, thereby changing the transmission direction of the bass signal from the subwoofer 130. The motor rod of the stepper motor is fixedly connected to the center of the second gear 110. Rotating the motor rod of the stepper motor synchronously rotates the second gear 110, and the second gear 110 synchronously rotates the first gear 120 meshing with it. The gear ratio between the first gear 120 and the second gear 110 is set according to the specific adjustment precision and adjustment requirements, and is not limited here.

[0029] In some optional embodiments, the first tweeter includes a first tweeter 200, a first sound cavity 210, and a first tweeter processor 230. The sound outlet of the first tweeter 200 is connected to a first end of the first sound cavity 210, and the second end of the first sound cavity 210 is connected to the first tweeter processor 230.

[0030] Specifically, the first acoustic cavity 210 can adjust the acoustic impedance of the sound source (i.e., the first tweeter 200), improving the electroacoustic conversion efficiency of the sound source. Simultaneously, the first acoustic cavity 210 converges the high-frequency signal and converts the spherical wave high-frequency signal generated from the sound source into a cylindrical wave high-frequency signal output from the sound outlet, thereby improving the volume, propagation distance, and directivity of the high-frequency signal generated by the first tweeter 200. The first tweeter processor 230 can absorb and process the high-frequency signal, enabling corresponding attenuation and reduction, facilitating appropriate adjustment of the high-frequency signal to meet the user's high-frequency signal requirements at different locations within the venue, improving the overall sound effect and enhancing the user experience.

[0031] In some optional embodiments, the first horn includes a first baffle 220 and a second baffle 240. The first baffle 220 is disposed on a first side of the first tweeter 230 and is rotatably connected to the first tweeter 200 via a first rotating shaft 221. The second baffle 240 is disposed on a second side of the first tweeter 230 and is rotatably connected to the first tweeter 200 via a second rotating shaft 241.

[0032] Specifically, the first baffle 220 rotates via a first rotating shaft 221, which can be driven by a stepper motor. Rotating the first shaft synchronously rotates the first baffle 220, thus changing its direction. Similarly, the second baffle 240 rotates via a second rotating shaft 241, which can also be driven by a stepper motor. Rotating the second shaft synchronously rotates the second baffle 240, thus changing its direction. The first and second baffles 220 work together to guide the high-frequency signal from the first high-frequency processor 230. The rotation angles of the first and second shafts are determined by a preset stepper motor rotation angle, which can be set according to requirements.

[0033] In some optional embodiments, the rotation angle range of the first baffle 220 and the rotation angle range of the second baffle 240 are both 0-90°.

[0034] Specifically, the rotation angle range of the first baffle 220 is from the angle where the first baffle 220 is perpendicular to the first tweeter 230 to the angle where the first baffle 220 is parallel to the first tweeter 230; the rotation angle range of the second baffle 240 is from the angle where the second baffle 240 is perpendicular to the first tweeter 230 to the angle where the second baffle 240 is parallel to the first tweeter 230. The rotation angle range is wide, the adjustment range is large, and the applicability is strong.

[0035] In some optional embodiments, the second tweeter includes a second tweeter 310, a second sound cavity 320, and a second tweeter processor 330. The sound outlet of the second tweeter 310 is connected to a first end of the second sound cavity 320, and the second end of the second sound cavity 320 is connected to the second tweeter processor 330.

[0036] Specifically, the second acoustic cavity 320 can adjust the acoustic impedance of the sound source (i.e., the second tweeter 310), improving the electroacoustic conversion efficiency of the sound source. Simultaneously, the second acoustic cavity 320 converges the high-frequency signal and converts the spherical wave-shaped high-frequency signal generated from the sound source into a cylindrical wave-shaped high-frequency signal output from the sound outlet, thereby improving the volume, propagation distance, and directivity of the high-frequency signal generated by the second tweeter 310. The second tweeter processor 330 can absorb and process the high-frequency signal, enabling appropriate attenuation and reduction, facilitating adjustments to the high-frequency signal to meet the user's high-frequency signal requirements at different locations within the venue, improving the overall sound effect and enhancing the user experience.

[0037] In some optional embodiments, the second horn 300 is provided on the second side of the second high-frequency processor 330, and the second sound cavity 320 is provided on the first side of the second high-frequency processor 330. The second horn 300 includes a horn cover, on which a first sound guide hole 306, a second sound guide hole 305 and a horizontal plate 301 are provided. The horizontal plate 301 is disposed between the first sound guide hole 306 and the second sound guide hole 305.

[0038] Specifically, by partially obscuring the front of the second tweeter processor 330 by the horizontal plate 301, the pressure in the gap between the horizontal plate 301 and the second tweeter can be increased, thereby increasing the acoustic impedance of the speaker and improving the electroacoustic conversion efficiency of the second tweeter. On the other hand, the sound waves generated by the second tweeter can be reflected by the horizontal plate 301 before being output. The horizontal plate 301 and the sidewalls of the first sound guide hole 306 and the second sound guide hole 305 form a horn structure that improves sound efficiency, improves the directionality of sound wave propagation, and increases the transmission distance of the sound waves. In addition, the sound waves generated by the second tweeter superimpose after bypassing the horizontal plate 301, which can increase the output volume of the second tweeter while keeping the power of the electrical signal input to the second tweeter constant. The second tweeter can improve its electroacoustic conversion efficiency, improve its sound wave transmission distance, and reduce its power consumption. The side of the horizontal plate 301 facing the second tweeter 310 is also provided with an arc-shaped groove 303, which can match the shape of the diaphragm of the second tweeter.

[0039] In some alternative embodiments, the first sound guide hole 306 includes a first inclined surface 302 having a first tilt angle, and the first sound guide hole 306 includes a second inclined surface 304 having a second tilt angle.

[0040] Specifically, the direction of the sound wave after passing through the first sound guide hole 306 is changed by the first tilt angle of the first inclined surface 302. Similarly, the direction of the sound wave after passing through the second sound guide hole 305 is changed by the second tilt angle of the second inclined surface 304, thereby changing the transmission direction of the sound waves that are superimposed after passing through the horizontal plate 301. Therefore, the transmission direction of the high-frequency signal of the second tweeter can be changed by changing the first tilt angle of the first inclined surface 302 and the second tilt angle of the second inclined surface 304.

[0041] The implementation of this utility model embodiment has the following beneficial effects: This utility model embodiment provides an angle-adjustable speaker, including: a tweeter module and a woofer module. The tweeter module includes at least two first tweeters and at least one second tweeter. The woofer module includes at least two woofers 100. At least one woofer 100 is disposed at a first end and a second end of the tweeter module. A first horn is disposed at the junction of the woofer 100 and the first tweeter. The first horn is located at the sound outlet of the first tweeter and is rotatably connected to the first tweeter. The second tweeter is disposed between the first tweeters. A second horn 300 is disposed at the sound outlet of the second tweeter and is detachably connected to the second tweeter. By rotating the first horn to change the sound direction of the first tweeter, and by replacing the detachable second horn 300 to change the sound direction of the second tweeter, the sound angle of the speaker can be quickly adjusted, resulting in high adjustment efficiency and low adjustment cost.
