The upper housing 11 houses the speaker unit 20 and is fixedly connected to the lower housing 12.

When the ceiling speaker is mounted, the upper housing 11 of the ceiling speaker is hidden in a ceiling or a wall, the abutment ring abuts against the ceiling or the wall, the horn unit 20 is inclined to the ceiling or the wall in the direction (line c) of the horn unit 20, which can be regarded as the position when the ceiling speaker is mounted on the ceiling as shown in fig. 3. Therefore, when the ceiling or the wall surface opposite to the personnel gathering position (such as a sofa) cannot be installed, the ceiling type loudspeaker can be installed around, and sound can be well transmitted as long as the loudspeaker unit is guaranteed to face the personnel gathering position, so that good sound effect is maintained.

Further, in this embodiment, the speaker unit 20 includes a bass unit 21 and a treble unit 20, the sound emitting surface of the bass unit 21 is covered on the mounting opening 1203, a bracket 126 is disposed in the sound cavity 1201, and the treble unit 22 is fixed on the bracket 126 and is located below the sound emitting surface of the bass unit 21. The bass unit 21 and the treble unit 22 are integrated, so that the sound effect is better, and the bass unit 21 and the treble unit 22 can be reasonably installed, and the bass unit is simple in structure and reasonable in design.

Specifically, the bracket 126 includes a central fixing portion 124 and extension arms 125 extending from the central fixing portion 124, specifically, three extension arms 125, where the extension arms 125 are fixedly connected to the sound cavity shell 122, and the tweeter unit 22 is assembled on the central fixing portion 124, so that the tweeter unit 22 is suspended, and the sound propagation of the woofer unit 21 is not affected.

More specifically, the bracket 126, the abutment ring 121 and the acoustic cavity shell 122 are integrally formed together to form the lower housing 12, and the lower housing can be integrally injection molded by a mold, so that the manufacturing is simple and convenient, the parts are reduced, and the manufacturing process is simplified.

Of course, in other embodiments, the assembly structure of the bass unit 21 or the treble unit 22 is not limited thereto, or the speaker unit 20 is the treble unit 22 or the bass unit 21 alone.
