[0023] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described below in conjunction with the drawings and examples.It should be noted that the embodiments of the present application and the features in the examples can be combined with each other without conflict.

[0024] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can be practiced without resorting to the different ways described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description. Embodiment

[0025] Please refer to Figures 1-10 The utility model provides a kind of technical scheme: a sound box horn that can rotate and change horizontal and vertical angle, including base 1, the side fixedly connected of base 1 has connecting seat 2, the side of connecting seat 2 is connected with support 3, the outer surface edge of support 3 is fixed with installation frame 4, the inside of support 3 is fixedly installed with tweeter 5. Embodiment

[0026] Please refer to Figures 1-10 The outer surface of base 1 is through and is equipped with base mounting hole 6, the outer surface of installation frame 4 is through and is equipped with frame mounting hole 7, support 3 is integrally formed, the up and down and left and right edges of installation frame 4 are straight edge, and diagonal edge is arc edge.

[0027] Working principle: during installation, the installation frame 4 can be adjusted in the way of installing the horn, which can be rotated and fixed to change the installation direction, and then the horn can be fixed through the base mounting hole 6, and the integrally formed support 3 can improve the sound production efficiency: the horn design can effectively couple the driver with the air through the "acoustic impedance matching" phenomenon, so as to produce louder, faster and wider dynamic range sound. This design makes the sound production efficiency of the horn speaker much higher than that of ordinary speakers, usually reaching 30-50% efficiency, while the efficiency of ordinary closed speakers is only about 1%, reducing distortion and improving sound quality: due to the design of the horn, the loudspeaker unit diaphragm can push more air at a smaller amplitude, thus significantly reducing distortion and improving sound quality. This design makes the horn speaker provide high-quality audio output even at low power, enhancing directivity and controlling sound dispersion: the horn structure has strong directivity, which can reduce sound scattering and reflection, thereby better controlling the direction of sound propagation. This helps to provide more concentrated sound output in a specific direction, reducing reflected sound from the side wall or ceiling, making the sound sound more real and direct, and improving dynamic range and sound pressure: due to its high energy conversion capability, the horn speaker can provide higher sound pressure at the same input power, which means it can output higher sound pressure level and has larger dynamic range. This is very advantageous for applications that require large dynamic range and high sound pressure level, reducing interference between units: through the precise design of the horn structure, interference between different units can be effectively reduced to ensure that the sound output of each unit can be accurately combined together to improve overall sound quality. Use the horn as an array sound source, when the horn's horn mouth's propagation angle is 25°, the interference between the horns is small, and it can also be used as a point sound source.

[0028] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments without departing from the technical scheme of the present application, according to the technical essence of the present application, still belongs to the protection scope of the present application.
