Loudspeaker equipment for ships

Abstract

The invention discloses marine loudspeaker equipment which comprises a rod member and an assembly portion in sliding fit with the rod member. A sliding cavity is arranged on the right side in the rod member, a stud is arranged in the sliding cavity, the top end of the stud is connected with a first motor, and an inserting connection portion with an oblique sliding portion is fixedly arranged in the middle of the top end of the inner wall on the left side of the sliding cavity; the assembly portion is arranged in the sliding cavity and is in sliding fit with the same and in threaded fit connection with the stud, an inserting connection groove with an oblique groove is formed in the middle of the top end of the left end face of the assembly portion, a containing cavity is arranged in the middle in the assembly portion, a steering shaft is arranged on the right side in the containing cavity, the top end of the steering shaft penetrates the assembly portion to upwards extend and run for matched connection, the top end of the steering shaft is in running connection with a turnplate, and a loudspeaker is arranged on the top face of the turnplate. The marine loudspeaker equipment is simple in structure, convenient to operate, supportive of adjusting of sound amplifying direction at proper time and convenient for maintenance, and using efficiency is improved.

Description

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

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
