[0002] In the past, in traditional speaker line array products, the low-frequency units were arranged horizontally, and the high-frequency unit horns were in the middle of the line array. The low-frequency units could not be arranged closely, and the center distance of the units could not be minimized. The sound wavelength was longer than the center distance of the low-frequency units, which caused the working frequency to be unable to be fully coupled. As a result, some frequency bands were not transmitted far, and even cancellation occurred. The sound system of traditional line array products must have a good building acoustic environment and the reverberation time must reach the specified value to achieve good results. This often requires a very high investment cost in the building acoustic environment of large buildings. In addition, the line array of horizontally arranged low-frequency units has a high cost. Although the sound energy is large, it will not work well in a large space with long reverberation. Therefore, in order to avoid the shortcomings of the prior art, it is necessary to improve the prior art. Summary of the invention

[0013] Compared with the prior art, the present invention installs a first high-Q value 8-inch low-frequency sound transducer module and a second high-Q value 8-inch low-frequency sound transducer module in the vertical direction through a sound transducer bracket arranged in the vertical direction.

A first high-Q value 8-inch low-frequency sound transducer module 2 and a second high-Q value 8-inch low-frequency sound transducer module 3 are installed in the vertical direction through the sound transducer bracket 1 arranged in the vertical direction. The first high-Q value 8-inch low-frequency sound transducer module 2 includes four first high-Q value 8-inch low-frequency sound transducers 4 arranged in sequence in the vertical direction. The second high-Q value 8-inch low-frequency sound transducer module 3 includes two second high-Q value 8-inch low-frequency sound transducers 5 arranged in sequence in the vertical direction. Every two first high-Q value 8-inch low-frequency sound transducers in the first high-Q value 8-inch low-frequency sound transducer module 2 have a first high-Q value 8-inch low-frequency sound transducer 4 arranged in sequence in the vertical direction. The low-frequency sound transducers 4 are connected in series and then in parallel, the second high-Q value 8-inch low-frequency sound transducer 5 in the second high-Q value 8-inch low-frequency sound transducer module 3 is connected in series, and the impedance of the first high-Q value 8-inch low-frequency sound transducer module 2 is equal to the impedance of the second high-Q value 8-inch low-frequency sound transducer module 3, so that the power of the first high-Q value 8-inch low-frequency sound transducer 4 and the second high-Q value 8-inch low-frequency sound transducer 5 are equal, and the sound field is evenly distributed, which saves power amplifiers while maximizing sound energy, effectively saving electricity resources and reducing production costs and use costs.
