Through the annular groove 421, it is convenient to fix the sound column.

[0058] The traditional speaker is only half - a - person - high, and the music played by the speaker 112 cannot reach the ears of standing people fastest. Therefore, by adding sound columns to increase the height and connecting the column - shaped speakers and the male plug 4 on the speaker body 11, the whole speaker becomes a plastic - shell sound - column support box, enabling the sound to be transmitted to the ears of standing people faster and having a larger sound diffusion range.

[0059] The height of the sound - column audio system can be adjusted according to requirements (by increasing or decreasing the number of column - shaped sound columns to adjust the height) to obtain the best sound coverage (the height - adjusting columns can be removed when the audience is sitting and listening). An adjustable ultra - long delay time DSP setting (0.25 - meter step) is provided. When multiple audio systems are cascaded and the back - field supplementary audio system needs to increase the delay, it is phase - synchronized with the main sound - column system.

[0060] This embodiment not only has the advantages of light weight, small volume, and convenient carrying compared with ordinary combined speakers, but also has the characteristics of high sound quality clarity, wide horizontal coverage angle, high sound pressure level, and long radiation distance.

[0061] Integrate multiple types of devices such as wireless microphones, mixing consoles 2, peripheral devices, power amplifier components 113, speakers 112, speaker bodies 11, etc. into one, which greatly simplifies the work of professionals such as the connection, installation, and debugging of the speaker system, greatly reduces the difficulty of tuning, liberates the work of professional sound engineers, and allows ordinary personnel or performers to adjust in real time according to on-site needs. It is suitable for sound reinforcement in application scenarios such as salons, wine parties, band performances, open-air dances, and conference room sound reinforcement.
