Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker device used on ships. Background technique [0002] At present, loudspeaker equipment is often used on some police ships, and its main function is to increase the volume when an emergency occurs or to check passing ships, which is beneficial to the auditory effect. Existing loudspeaker equipment is generally fixed on the top of the ship or supported to a certain height, which increases the difficulty of overhaul and maintenance. At the same time, because the loudspeaker is fixed, it can only be amplified in one direction. , it is difficult to achieve the best sound amplification effect for the back or side direction, which seriously limits the direction of sound amplification and is not conducive to the propagation of sound. There are also many sound amplification devices that can adjust the direction by themselves, but they are expensive , the installation is...

Problems solved by technology

Existing loudspeaker equipment is generally fixed on the top of the ship or supported to a certain height, which increases the difficulty of overhaul and maintenance. At the same time, because the loudspeaker is fixed, it can only be amplified in one direction. , it is difficult to achieve the best sound amplification effect for the back or side direction, which seriously limits the direction of sound amplification and is not conducive to the propagation of sound. There are also many sound amplification devices that can adjust the direction by themselves, but they are expensive , the installation is more inconvenient, not suitable for promotion and use
