Description

Technical Field

[0001] The utility model relates to the technical field of directional strong-voice loudspeakers for ships, in particular to a directional strong-voice loudspeaker. Background Art

[0002] A directional loudspeaker is a sound transmission device that can efficiently focus sound to a specific location or target object. It uses ultrasonic or electroacoustic technology, through special design and structure, to focus the sound into a narrow beam, and transmit it to the target object so that it can hear the sound clearly and unambiguously. Directional loudspeakers are usually installed on ships, which are of great significance in combating illegal activities such as piracy, smuggling, illegal immigration, and drug trafficking, and are an important means to maintain national security and protect the lives and property of the people.

[0003] However, when existing directional loudspeakers are installed and used on ships, most of the traditional installation methods are bolt fixing and welding. Bolt fixing is often impacted by seawater when used on ships. The bolt fixing method will inevitably be corroded by seawater over a long period of time, resulting in instability when the loudspeaker rotates. It is not practical, and the bolts are rusted and difficult to disassemble and replace. The welding method is also extremely inconvenient to disassemble and replace later. Moreover, the installation method does not have a sealing function and cannot avoid seawater erosion, resulting in a shortened life of the installed parts. Utility Model Content
