A kind of marine loudspeaker equipment

Abstract

The invention discloses loudspeaker equipment for a ship. The loudspeaker equipment for the ship comprises a rod piece and an assembling part which is in sliding fit with the rod piece; a slide chamber is formed in the internal right side of the rod piece; a stud is arranged in the slide chamber; the top end of the stud is connected with a first motor; an inserting block with an inclined sliding part is fixedly arranged at the middle part of the top end of the inner wall of the left side of the sliding chamber; an assembling part is arranged in the slide chamber and in sliding fit with the slide chamber; the assembling part is connected with the stud in the form of screw-thread fit; an inserting groove with an inclined groove is formed in the middle part of the top end of the end surface of the left side of the assembling part; an accommodating chamber is formed in the middle part of the interior of the assembling part; a steering shaft is arranged on the right side of the interior of the accommodating chamber; the top end of the steering shaft penetrates through the assembling part to extend upwards and is connected with the assembling part in the form of running fit; the top end of the steering shaft is connected with a turntable in the form of running fit; and a loudspeaker is arranged on the top surface of the turntable. The loudspeaker equipment for the ship has the advantages that the loudspeaker equipment for the ship is simply structured and convenient to operate, the sound amplifying direction can be adjusted in time, the loudspeaker equipment for the ship is convenient to overhaul and maintain and the service efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to marine loudspeaker equipment. 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 relat...

AI Technical Summary

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
