Marine Diaphragmatic Air Horn – Enhanced Safety Sound Signaling for Marine Navigation
Description:
The Marine Diaphragmatic Air Horn is a sophisticated device that utilizes a diaphragm and compressed air to resonate and transmit distinct, attention-grabbing sounds. It is specifically designed to send out signals with different coded information, adhering to international maritime conventions, thereby effectively communicating a ship’s navigation information to surrounding vessels for safe avoidance. When used as the sole whistle on board, the directional whistle should be installed to direct maximum sound intensity forward. For optimal performance, the horn should be placed as high as possible on the boat to minimize sound obstruction and reduce the risk of hearing damage to the operator. The sound pressure value at the listening point on board should not exceed 110 dB(A). If the distance between horns exceeds 100 meters, arrangements should be made to prevent simultaneous playback. In areas where the sound field of a single horn is significantly reduced, a combined horn system is recommended to overcome this reduction, treating the combined system as a single whistle. The distance between horns in the combined system should not exceed 100 meters, and they should be arranged to play simultaneously, with each horn’s frequency differing by at least 10 Hz from others.
Features:
- Loud and Attention-Grabbing Sound: Designed to produce a powerful sound that can be heard over long distances, ensuring effective communication in maritime environments.
- High-Quality, Corrosion-Resistant Materials: Constructed from stainless steel, brass, or bronze to withstand harsh marine conditions and resist damage from saltwater and weather.
- Variety of Sizes and Configurations: Available in compact models for smaller boats and larger models for larger ships, catering to different vessel types and applications.
- Easy Installation and Maintenance: Simple to install and maintain, requiring only a source of compressed air for operation.
- Compliance with International Regulations: Required by international maritime regulations to be installed on all vessels over a certain size, adhering to COLREGs and SOLAS standards.
- Long Service Life: Durable and reliable, capable of operating for many years without extensive maintenance or replacement.
Application:
The Marine Diaphragmatic Air Horn is suitable for various ships, serving as an alarm signal source in scenarios such as port entry, voyage avoidance, or poor visibility conditions.

Main Components:
The Marine Diaphragmatic Air Horn consists of two main parts: the sound system and the automatic control system.
- Sound System: Comprises an electric motor, driven gear, eccentric shaft, piston, piston cylinder, sound generator (sound diaphragm), resonator, horn, and other parts. These components are mechanically connected to form a unified whole with independent functions.
- Automatic Control System: Features a microcomputer with a “single chip” as the core, ensuring precise and reliable operation.
