Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker device that is easy to assemble and disassemble. Background technique [0002] In some public places with a large flow of people, such as (hospitals, schools, railway stations, etc.), loudspeaker equipment is often used for sound amplification. Existing loudspeaker equipment is generally fixed on the top wall by screws or screws. When maintenance is required, it needs to be installed and disassembled by tools. It has problems such as difficult replacement and slow replacement speed, which seriously affects work efficiency. At the same time, the contact piece of the existing loudspeaker equipment leaks outside, which increases the risk of electric shock during maintenance and has a relatively large potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a loudspeaker device that is ...
