What is the 'Virtual Speaker' mode?

In this mode, the speaker points at an object (like a digital sign) rather than the user. The sound beam bounces off the object, making it appear as if the sound originates from the object itself.

What are the audio input options?

The speaker supports multiple input methods including Bluetooth 5.0, TF card, U-disk, and a 3.5mm audio line.

What is the minimum order quantity?

The minimum order quantity is 1 piece.
