[0025] The first sound module 2 includes a tweeter 21, a loudspeaker 22 and a sound filter cover 23. The loudspeaker 22 is installed at the tweeter 21. The loudspeaker 22 and the tweeter 21 are fixedly installed in the box 1. The sound filter cover 23 is installed in the loudspeaker 22. A plurality of sound filter holes 24 are evenly arranged on the sound filter cover 23. The hemispherical sound filter cover 23 can evenly reflect part of the sound waves at the loudspeaker 22, so that the sound waves in the loudspeaker 22 collide, eliminating noise and making the sound stronger.

[0026] The second sound-emitting module 3 includes an echo cover 31, a fixed frame 33 and a woofer 35, and the echo cover 31 is installed on the fixed frame 33; the echo cover 31 is used to reflect part of the sound waves emitted by the woofer 35, and the fixed frame 33 is used to install the echo cover 31 on the woofer 35; the echo cover 31 is an arc-shaped structure, and a plurality of irregular sound outlet holes 32 are densely distributed on the echo cover 31; the arc-shaped echo cover 31 can evenly reflect the sound waves of the woofer 35, and the irregular sound outlet holes 32 are used for the sound of the woofer 35, as well as filtering the sound of the woofer 35, and allowing part of the sound to be transmitted to the box body 1; a phase plug 34 is provided in the middle of the inner side of the echo cover 31, and the phase plug 34 can improve the axial and off-axis frequency response of the woofer 35, so that the sound wave scattering is more uniform, the intermediate frequency is more natural, and the sound effect is better.

[0027] The control unit includes a control panel 4 and a built-in battery. The control panel 4 is electrically connected to the built-in battery, the tweeter 21, and the woofer 35.

[0028] The number of the first sound emitting modules 2 and the number of the second sound emitting modules 3 are both two.

[0029] The specific real-time process is as follows:

[0030] When using the present high-quality mixing speaker, the sound source input device is connected to the control panel 4 so that the sound source input device can be connected to the tweeter 21 and the woofer 35. When the tweeter 21 of the first sound module 2 makes a sound, the sound of the tweeter 21 is amplified by the amplifying horn 22, and the sound filter 23 filters and reflects the sound at the amplifying horn 22. At the same time, the woofer 35 of the second sound module 3 makes a sound, and the sound hits the inside of the echo cover 31. The echo cover 31 cooperates with the phase plug 34 to partially reflect the sound, so that the sound collides in the echo cover 31, and the noise emitted by the speaker is offset, so that the sound quality of the present high-quality sound speaker is better. At the same time, the echo cover 31 reflects part of the sound to delay the sound, and the reflected sound cooperates with the original sound to make the sound rich in layers and more powerful and smart. The sounds of the first sound module 2 and the second sound module 3 are mutually transmitted and mixed through the sound guide hole 51 at the partition 5, so that the mixing effect of the present speaker is better.

[0031] The high-quality mixing speaker emits sound through the woofer 35 of each second sound module 3, and the sound hits the inside of the echo cover 31. The echo cover 31 cooperates with the phase plug 34 to partially reflect the sound, so that the sound collides in the echo cover 31, and the noise emitted by the speaker is offset, so that the sound quality of the high-quality mixing speaker is better. At the same time, the echo cover 31 reflects part of the sound to delay the sound, and the reflected sound cooperates with the original sound to make the sound rich in layers and more powerful and flexible. The first sound module 2 enters the space where the second sound module 3 is located through the sound guide hole 51 on the partition 5, and at the same time, the second sound module 3 enters the space where the first sound module 2 is located through the sound guide hole 51 on the partition 5, so that the mixing effect of the speaker is better.
