Technical Field

[0001] The utility model relates to the technical field of a multi-speaker sound box, in particular to a multi-speaker sound box with anti-interference effect. Background Art

[0002] A speaker is a device that converts audio signals into sound. A speaker is usually composed of a speaker unit, a cabinet, a crossover and other parts. After the audio signal is input into the speaker, the vibration of the speaker unit pushes the air to produce sound waves, thereby making sound.
