Ceiling-absorbing loudspeaker

Abstract

The invention relates to a ceiling loudspeaker for sound, in particular a ceiling speaker, comprises a loudspeaker box body and a main loudspeaker, a subwoofer radiator and a tweeter respectively positioned in the loudspeaker box body, wherein the loudspeaker box body is an independent sealed box body, the main loudspeaker and the tweeter loudspeaker are installed on the front box wall of the loudspeaker box body, and the subwoofer radiator is installed on the front box wall and / or the rear box wall of the loudspeaker box body; at least one rear bass sound outlet hole is formed at the edge ofthe front box wall. As that main loudspeaker and the bass radiator interact with each other, the bass is greatly improved, and the sound quality of the conventional ceiling loudspeaker is superior tothat of the conventional ceiling loudspeaker by using a 3.5-inch ordinary loudspeaker; at that same time, the cost is reduced, the installation height is low, the volume is small, the weight is light,the ceiling is self-contained, and the installation and use of the ceiling are more convenient.

Description

technical field [0001] The invention relates to a ceiling-absorbing loudspeaker for audio, in particular to a ceiling-absorbing sound box. Background technique [0002] Ceiling speakers are generally installed on the indoor ceiling (also known as the ceiling, etc.) or hidden on the wall (on the car wall, etc.). In recent years, with the advancement of technology, people have higher and higher requirements for the playback sound quality of ceiling speakers (also known as ceiling speakers, hidden speakers, etc.), and the installation height requirements are getting smaller and smaller. In the "Speaker and Sound Box Design Manual" published by Fujian Science and Technology Press in July 2008, the closed sound box (60-67 pages), the open-type sound box (67-77 pages), the passive radiation sound box (77 pages) are disclosed. ~78 pages); These disclosed prior art loudspeakers, or volume is too big, installation height is too big, or bass sound reproduction effect is not good.

Problems solved by technology

In the "Speaker and Sound Box Design Manual" published by Fujian Science and Technology Press in July 2008, the closed sound box (60-67 pages), the open-type sound box (67-77 pages), the passive radiation sound box (77 pages) are disclosed. ~78 pages); These disclosed prior art loudspeakers, either volume is too big, installation height is too big, or bass sound reproduction effect is not good

The ceiling speaker of the prior art is just a speaker with a mounting frame, its caliber is generally 5.25 inches to 8 inches, it is installed on the ceiling, and the space of the ceiling is used as the "cabinet", because it cannot be sealed, And the ceiling space is either too large or too small, so it is impossible to realize a real speaker cabinet, at best it is an acoustically large baffle. In addition, the height of these speakers in the prior art is very large, all above 80mm, and the installation space of the ceiling It is also very limited, which makes it very difficult to install and use the ceiling speaker
