Technical Field

[0001] The utility model relates to the field of electronic products, in particular to a four-directional speaker box. Background Art

[0002] With the development of audio technology, consumers have higher and higher requirements for the sound quality of speakers. The traditional two-channel stereo system of speakers can no longer meet the needs in some scenarios, especially in home theaters, large conference halls or outdoor activities where a wider coverage range is required.

[0003] Early speaker designs mainly focused on how to effectively allocate the positions of various sound units and how to optimize the sound wave propagation path. Due to early technological limitations, the sound performance of the speaker in different directions may be inconsistent, resulting in the sound quality heard in some positions being worse than in other positions. Sound waves in different directions may interfere with each other in space, generating unnecessary noise or causing distortion of certain frequencies. Summary of the Invention

[0004] The purpose of the utility model is to provide a four-directional speaker box to solve the problem of mutual interference of sound waves in space.
