Accordingly, in the embodiment of the present application, the main housing 1, the base 2, and the lamp cover 3 are connected together to form a housing of the speaker lamp 100.

As shown in fig. 1, a cavity may be formed within the housing.

The speaker light fixture 100 according to an embodiment of the present application may further include a heat sink 4, a circuit board 5, a reflector 6, and a speaker 7. As shown in fig. 1, the heat sink 4 is disposed within the cavity and divides the cavity into an upper cavity 131 and a lower cavity 132. A circuit board 5 may be disposed within the upper cavity 131 and connected to the heat sink 4, and one or more LED light sources 51 may be disposed on the circuit board 5. The reflector 6 has an open upper end 61 and an open lower end 62, and the reflector 6 may be hollow to enclose a reflector cavity 63, the lower end 62 of the reflector 6 being connected to the circuit board 5, and the LED light sources 51 surrounding the outside of the reflector 6. In the embodiment of the present application, as shown in fig. 5, a plurality of LED light sources 51 arranged circumferentially around the perimeter of the circuit board 5 are provided on the circuit board 5, but the number and arrangement of the LED light sources are not limited thereto. The speaker 7 may be mounted at the upper end 61 of the reflector 6 and housed within a reflector cavity 63.

Specifically, as shown in fig. 1, there may be a space 64 between the speaker 7 and the circuit board 5 within the reflector cavity 63. With such an arrangement, a part of the light emitted by the LED light source 51 can be reflected by the reflector 6, thereby enhancing the light emitting efficiency of the speaker light fixture 100. Further, since there is a space 64 in the reflector 6 below the speaker 7, the space 64 can function as a resonance chamber, and the speaker can generate sound with a better sound quality.

As shown in fig. 1 and 2, an opening portion 33 corresponding to the speaker 7 is provided on the housing, specifically, the opening portion 33 is provided at the top end 31 of the lamp cover 3 so that the sound from the speaker 7 can be propagated to the outside of the speaker lamp 100 via the opening portion 33.

Specifically, as shown in fig. 3 and 4, a laterally extending tip flange 71 may be formed at the tip of the speaker 7, the tip flange 71 resting on a corresponding receiving portion 65 formed at the upper end 61 of the reflector 6 and being sealingly connected to said upper end 61 of the reflector 6, that is, a sealing structure is formed at the connection of the speaker 7 and the reflector 6.

Specifically, as shown by the arrows in fig. 1, the communication of the space 64 with the upper chamber 131 is achieved by the arrangement of the first and second through holes 52 and 53 and the communication passage P. With this arrangement, the volume of the resonance chamber is increased to provide better sound quality.

Referring to fig. 7, fig. 7 is a graph of SPL (sound pressure level) versus frequency for a loudspeaker fixture 100 according to an embodiment of the present application compared to a conventional loudspeaker fixture. The dashed curves in fig. 7 show the SPL at different frequencies for a loudspeaker light fixture 100 according to the present application, while the solid curves in fig. 7 show the SPL at different frequencies for a conventional loudspeaker light fixture without a reflector and a through hole in the circuit board.

As can be seen from fig. 7, the speaker light fixture 100 according to the embodiment of the present application has a better SPL at high frequencies and thus has a better sound quality, compared to the conventional speaker light fixture. In addition, the SPL of the speaker light fixture 100 according to the embodiment of the present application is also more stable in the overall frequency, and thus the overall sound quality level is also improved.

According to another embodiment variant, not shown, the loudspeaker light fixture may comprise: a base connected to an external power source to provide power required by the speaker lamp; a housing disposed on the base; a circuit board; a reflector; and a speaker. A circuit board is disposed within the housing and has a plurality of LED light sources mounted thereon.
