How does the directional speaker work?

It uses ultrasonic waves to create a narrow beam that spreads directionally in the air, controlling sound waves to a specific area where the volume is high, while remaining quiet outside that area.

What are the audio input options?

The speaker supports 3.5mm audio input, Bluetooth 5.0, and TF card/U-disk playback.
