Outdoor directional speakers for river channels can be used for water safety warnings and navigation guidance. By installing outdoor directional speakers around waterways such as river channels or lakes, sound can be propagated in a directional manner to warn and guide passing ships.For example, in busy waters, such as ports or ship intersections, outdoor directional speakers can emit sounds to remind ships to pay attention to safe distances, sailing directions, and speeds. Such warnings can avoid collisions and ensure safe navigation.

In addition, outdoor directional speakers can also be used to release navigation information, such as water levels, currents, weather, etc. This information can help crews better understand water conditions and make correct navigation decisions.

In short, the use of outdoor directional speakers on river channels can improve the safety and efficiency of water traffic, while also providing more accurate and timely navigation information to crews.
