Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, and more specifically, to a ceiling-mounted loudspeaker. Background Art

[0002] A ceiling speaker is an electro-acoustic conversion device installed on the ceiling. It is used to convert the audio electrical power signal input by the amplifier into an acoustic power signal and then radiate it in the form of sound waves to the space where sound is needed. It is generally used in public places, where the audio power signal is input in a constant voltage manner. There are also places where the space is not too large, where the signal is input in a constant resistance manner. Most of the common ceiling speakers on the market are fixed to the ceiling with bolts, which makes it more troublesome to repair them with the help of tools when disassembling them. In addition, the bottom of the speaker is prone to sticking to a lot of dust and mosquitoes, which can easily clog the speaker holes after long-term use, affecting the sound volume of the speaker.
