Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0038] like Figures 1-2 As shown, this embodiment of the invention proposes an audio lighting device, including a speaker body 1, a lamp body 2 connected to the speaker body 1, and an audio control device 4. The audio control device 4 includes a back plate 41 connected to the lamp body 2, a circuit board assembly 42 disposed on the back plate 41, and a wireless receiver 43 electrically connected to the circuit board assembly 42. The circuit board assembly 42 is electrically connected to the speaker body 1. The back plate 41 can also be connected to the speaker body 1 alone, or connected to both the lamp body 2 and the speaker body 1 simultaneously.

[0039] In the embodiment of the present application, the audio control device 4 is integrally mounted on the lamp body 2 through the back plate 41, and the sound body 1, the lamp body 2 and the audio control device 4 are fixedly mounted as a whole. When in use, the wireless control device (which can be a wireless microphone) sends a broadcast signal to the wireless receiving member 43, and the circuit board assembly 42 processes the broadcast signal and controls the sound body 1 to generate corresponding sound waves, thereby realizing the integration of broadcasting and lighting. The circuit board assembly 42 has corresponding circuits for controlling the sound in the prior art, and the wireless receiving member 43 is a module that can receive audio signals through wireless reception.

[0040] Further, please refer to Figure 1 As another specific embodiment of the sound lighting device provided by the present application, the audio control device 4 is located at the back of the lamp body 2. When the sound lighting device is hung in a ceiling or other use environment, the sound lighting device as a whole shields the audio control device 4, thereby realizing the aesthetic appearance of the sound lighting device as a whole. The back of the sound lighting device is the back surface of the lamp body 2 in the direction of illumination. The back plate 41 is fixedly connected with the back of the lamp body 2, and the wireless receiving member 43 is arranged at the central position of the back plate 41.

[0041] Further, please refer to Figure 2 As another specific embodiment of the sound lighting device provided by the present application, the wireless receiving member 43 is an infrared receiving module, the shell of the infrared receiving module is provided with a grid-shaped receiving hole, and the surface of the shell is provided with an infrared receiving film for increasing the receiving rate of infrared signals. The microphone used in cooperation with the infrared receiving module is internally provided with an infrared emitting module. When in use, the user's voice is converted into an infrared audio signal through the infrared emitting module, the infrared audio signal is transmitted to the infrared receiving module, and is transmitted to the inside of the sound body 1 through the corresponding circuit of the audio control device 4, and is broadcast through the corresponding loudspeaker. For example, when a teacher is giving a lecture in a classroom, the teacher speaks into the microphone at any position in the classroom, and the microphone can send a signal to the infrared receiving module to realize the sound generation of the sound body 1. The receiving hole can improve the strength of infrared reception. The audio control device 4 can further include an external shell 44 covering the back plate 41, which is made of a plastic material with low absorption of infrared waves, so as to facilitate the transmission of infrared signals.

[0042] Further, please refer to Figure 2As another specific embodiment of the sound and light device provided by the present application, the circuit board assembly 42 comprises a first circuit board 421 perpendicular to the back plate 41, and the wireless receiving member 43 is located on the top of the first circuit board 421 and is electrically connected with the first circuit board 421 (the position where the first circuit board 421 contacts the back plate 41 is the bottom, and the position away from the back plate 41 is the top). The first circuit board 421 is arranged perpendicular to the back plate 41, so that the wireless receiving member 43 mounted on the top of the first circuit board 421 is in the highest position relative to other components, and other components do not block the signal receiving of the wireless receiving member 43, thereby improving the signal receiving effect of the wireless receiving member 43. The circuit board assembly 42 can further comprise a second circuit board 422 laid on the back plate 41, the first circuit board 421 and the second circuit board 422 comprise control circuits for controlling sound emission, and can further comprise other modules for receiving broadcast and network data to adapt to different use requirements, so as to meet the diversification of teaching in a classroom.

[0043] Further, referring to Figures 2-4 As another specific embodiment of the sound and light device provided by the present application, the back plate 41 is provided with a mounting structure for mounting the first circuit board 421; the mounting structure comprises two opposite and spaced fixed vertical plates 411 and at least one elastic vertical plate 412 located between the two fixed vertical plates 411; each fixed vertical plate 411 is provided with a fixed groove 4111, and the opposite ends of the first circuit board 421 are respectively inserted into the fixed grooves 4111, and the side surface of the first circuit board 421 abuts against the elastic vertical plate 412. The first circuit board 421 is fixedly mounted on the back plate 41 through the mounting structure, and the mounting process is as follows: the elastic vertical plate 412 is deflected by being pushed, so that the opposite ends of the first circuit board 421 are respectively inserted into the fixed grooves 4111 on the two fixed vertical plates 411, and then the elastic vertical plate 412 is released to reset and abut against the first circuit board 421, so that the first circuit board 421 is fixedly mounted, the operation is simple, and the first circuit board 421 does not deflect to both sides when the top of the first circuit board 421 bears the wireless receiving member 43, thereby ensuring the stability of the first circuit board 421.

[0044] Further, referring to Figures 3-4As another specific embodiment of the sound and light device provided by the present application, the elastic upright plate 412 is provided with a limiting hook 4121 at the end away from the back plate 41, and the limiting hook 4121 abuts against the top of the first circuit board 421. When the elastic upright plate 412 is reset to abut against the side of the first circuit board 421, the limiting hook 4121 at the end of the elastic upright plate 412 (i.e. the top of the elastic upright plate 412) is deflected and moves to abut against the top of the first circuit board 421, so that the first circuit board 421 cannot be separated from the fixing groove 4111 on the fixing upright plate 411, further ensuring the stability of the installation of the first circuit board 421.

[0045] Further, referring to Figure 3 As another specific embodiment of the sound and light device provided by the present application, the mounting structure further comprises a pressing block 413 abutting against the bottom of the first circuit board 421, and an elastic member 414 arranged between the pressing block 413 and the back plate 41. When the first circuit board 421 is fixedly installed on the back plate 41 through the mounting structure, the opposite ends of the first circuit board 421 are inserted into the fixing grooves 4111 on the two fixing upright plates 411, and the force is continuously applied to the first circuit board 421 so that the first circuit board 421 contacts the pressing block 413 and compresses the elastic member 414, then the elastic upright plate 412 is released to reset and abut against the first circuit board 421, the limiting hook 4121 on the elastic upright plate 412 abuts against the top of the first circuit board 421, and then the force applied to the first circuit board 421 is released, the elastic member 414 has a tendency to reset and applies a force to the first circuit board 421 through the pressing block 413, at this time, the pressing block 413 and the limiting hook 4121 apply forces to the first circuit board 421 at the opposite ends of the first circuit board 421, and the first circuit board 421 is limited in the vertical direction between the pressing block 413 and the limiting hook 4121. When the sound body 1 emits sound waves to make the sound and light device as a whole vibrate, the first circuit board 421 will not move in the vertical direction relative to the back plate 41, the fixing upright plate 411 and the elastic upright plate 412, that is, the first circuit board 421 is prevented from colliding with the back plate 41 and the elastic protrusion to generate noise, thereby ensuring the sound effect of the sound body.

[0046] Further, referring to Figure 3 As another specific embodiment of the sound and light device provided by the present application, the back plate 41 is provided with a pressing hole 415, and the elastic member 414 is connected to the inner wall of the pressing hole 415, so that the elastic member 414 can be located inside the pressing hole 415 and can be lower than the surface of the back plate 41, and the pressing hole 415 can serve as a limiting member for the lateral (perpendicular to the hole depth) deviation of the elastic member 414, to prevent the elastic member 414 from being damaged due to large lateral deviation under force.

[0047] Further, referring toFigure 3 As another specific embodiment of the sound and light device provided by the present application, the top pressing hole 415 is an elongated hole, and the elastic member 414 is an elastic arm integrally formed with the back plate 41. The free end of the elastic arm is connected to the top pressing block 413. When the top pressing block 413 is forced, the free end of the elastic arm deflects. The elastic arm is integrally formed with the back plate 41 to ensure the connection strength between the fixed end of the elastic arm and the back plate 41 when the elastic arm deflects.

[0048] Further, as another specific embodiment of the sound and light device provided by the present application, the top pressing hole 415 is a circular hole, and the elastic member 414 is a compression spring (the compression spring can be connected to the inner wall or the bottom of the top pressing hole 415). The top of the compression spring extends out of the top pressing hole 415. Therefore, when the elastic member 414 is a compression spring, the top of the elastic member 414 can replace the above-mentioned top pressing block 413.

[0049] Further, as another specific embodiment of the sound and light device provided by the present application, the top pressing hole 415 is a circular hole, and the elastic member 414 is a compression spring (the compression spring can be connected to the inner wall or the bottom of the top pressing hole 415). The top of the compression spring extends out of the top pressing hole 415. Therefore, when the elastic member 414 is a compression spring, the top of the elastic member 414 can replace the above-mentioned top pressing block 413. Figure 5 Figure 7 Further, as another specific embodiment of the sound and light device provided by the present application, the sound body 1 has a U-shaped first flange 11. The side of the sound body 1 close to the lamp body 2 has a first side wall 12. The lamp body 2 has a second flange 21 and a second side wall 22 parallel to the first side wall 12. The first side wall 12 is inclined to the plane where the first flange 11 and the second flange 21 are located. The inner wall of the annular mounting strip 3 is provided with a mounting groove 31. The first flange 11 and the second flange 21 are located in the mounting groove 31. The outer surface of the first side wall 12 of the sound body 1 is in contact with or clearance fit with the outer surface of the second side wall 22 of the lamp body 2. The sound body 1 and the lamp body 2 are fixedly connected to each other by the annular mounting strip 3. Therefore, the sound body 1 does not occupy the internal space of the lamp body 2. The light emitting area of the lamp body 2 is not blocked by the sound body 1, which ensures the light emitting effect of the lamp body 2. The sound waves emitted by the sound body 1 are not affected by the lamp body 2, which ensures the sound effect of the sound body 1.

[0050] The first flange 11 is arranged on the sound body 1 in a U shape. The first flange 11 can be arranged on other side walls of the sound body 1 except the first side wall 12. The second flange 21 is arranged on the lamp body 2. The second flange 21 can be arranged on other side walls of the lamp body 2 except the second side wall 22. Therefore, when the outer surface of the first side wall 12 of the sound body 1 is in contact with the outer surface of the second side wall 22 of the lamp body 2, and the first flange 11 and the second flange 21 are located in the mounting groove 31, the first flange 11 and the second flange 21 are located in the same plane. The first flange 11 and the second flange 21 can realize precise splicing around the sound body 1 and the lamp body 2. The sound body 1 and the lamp body 2 are fixedly connected to each other by the annular mounting strip 3. Therefore, the sound body 1 and the lamp body 2 are fixedly connected in a compact and integrated manner.

[0051] ​It can be understood that the first side wall 12 and the second side wall 22 can be in direct contact or in contact through a gasket or other connecting transition component.

[0052] Further, referring to Figure 7 , as another specific embodiment of the sound lighting device provided by the present application, the first side wall 12 is arranged obliquely relative to the plane where the first flange 11 is located, and the second side wall 22 is parallel to the first side wall 12. That is, the second side wall 22 and the first side wall 12 are both oblique, and parallel to each other. The lamp body 2 is a relatively large component, and is hung in the environment such as the ceiling together with the sound body 1. The shell of the lamp body 2 needs to have relatively large strength, so the second side wall 22 of the lamp body 2 is arranged to be oblique to improve the overall strength of the combination of the sound body 1 and the lamp body 2. The second side wall 22 is parallel to the first side wall 12, and when the second side wall 22 and the first side wall 12 are in contact, they can be in contact with the maximum area, thereby ensuring the compactness of the contact between the sound body 1 and the lamp body 2. Of course, in other embodiments, the second side wall 22 and the first side wall 12 are parallel and vertically arranged, which can be applied to the sound lighting device with a relatively small weight of the lamp body 2.

[0053] Further, referring to Figure 5 , as another specific embodiment of the sound lighting device provided by the present application, the sound body 1 is sequentially provided with a first shielding plate 13, a second shielding plate 14, a third shielding plate 15, and a fourth shielding plate 16 along the edge of the first side wall 12; the first shielding plate 13, the second shielding plate 14, the third shielding plate 15, and the fourth shielding plate 16 extend from the sound body 1 to cover the surface of the lamp body 2. The first shielding plate 13, the second shielding plate 14, the third shielding plate 15, and the fourth shielding plate 16 are sequentially distributed along the edge of the first side wall 12 and extend from the sound body 1 to the surface of the lamp body 2. Therefore, when the annular mounting strip 3 fixes and connects the sound body 1 and the lamp body 2 into one body, the first shielding plate 13, the second shielding plate 14, the third shielding plate 15, and the fourth shielding plate 16 can shield the gap at the connection between the sound body 1 and the lamp body 2, thereby improving the appearance of the sound lighting device, and foreign matters cannot fall into the gap between the second side wall 22 and the first side wall 12 after they are in contact.

[0054] Further, referring to Figure 5 and Figures 7-8As another specific embodiment of the sound lighting device provided by the present application, the fourth shielding plate 16 is provided with a reinforcing rib 161 on the side close to the accommodating gap 17, and the third flange 23 is provided with a slot corresponding to the reinforcing rib 161. The reinforcing rib 161 can improve the stability of the connection between the fourth shielding plate 16 and the main body of the sound body 1. Meanwhile, the reinforcing rib 161 on the fourth shielding plate 16 can cooperate with the slot on the third flange 23 to realize the positioning when the sound body 1 and the lamp body 2 are spliced, so that the sound body 1 and the lamp body 2 are accurately connected.

[0055] Further, referring to Figure 5 and Figure 8 As another specific embodiment of the sound lighting device provided by the present application, the fourth shielding plate 16 is provided with a reinforcing rib 161 on the side close to the accommodating gap 17, and the third flange 23 is provided with a slot corresponding to the reinforcing rib 161. The reinforcing rib 161 can improve the stability of the connection between the fourth shielding plate 16 and the main body of the sound body 1. Meanwhile, the reinforcing rib 161 on the fourth shielding plate 16 can cooperate with the slot on the third flange 23 to realize the positioning when the sound body 1 and the lamp body 2 are spliced, so that the sound body 1 and the lamp body 2 are accurately connected.

[0056] Further, as another specific embodiment of the sound lighting device provided by the present application, the first side wall 12 is provided with a first positioning slot, and the second side wall 22 is provided with a first positioning protrusion at a corresponding position of the first positioning slot. When the sound body 1 and the lamp body 2 are spliced, the first positioning protrusion on the second side wall 22 is inserted into the first positioning slot at the corresponding position of the first side wall 12, so that the boundaries of the first side wall 12 and the second side wall 22 completely coincide after the two are in contact, without the need for further adjustment of the position between the two, simplifying the installation steps of the sound lighting device. Meanwhile, when the first side wall 12 and the second side wall 22 are both inclined, after the first positioning protrusion is inserted into the first positioning slot at the corresponding position of the first side wall 12, the first side wall 12 and the second side wall 22 can also be prevented from sliding relative to each other.

[0057] Furthermore, as another specific embodiment of the audio lighting device provided by the present invention, a second positioning groove is provided on the second sidewall 22, and a second positioning protrusion located in the second positioning groove is provided on the first sidewall 12. When the speaker body 1 and the lamp body 2 are assembled, the second positioning protrusion on the first sidewall 12 is inserted into the corresponding second positioning groove on the second sidewall 22, so that the boundaries of the first sidewall 12 and the second sidewall 22 completely overlap after contact, without the need for further adjustment of their positions, thus simplifying the installation steps of the audio lighting device. At the same time, when both the first sidewall 12 and the second sidewall 22 are inclined, the insertion of the second positioning protrusion into the corresponding second positioning groove on the second sidewall 22 can also prevent relative sliding between the first sidewall 12 and the second sidewall 22.

[0058] Further, please refer to Figure 5 As another specific embodiment of the audio lighting device provided by the present invention, the audio body 1 has a wire hole 18, and the first circuit board 421 is connected to a cable. The cable passes through the wire hole 18 and is electrically connected to the speaker inside the audio body 1.

[0059] Further, please refer to Figure 5 As another specific embodiment of the audio lighting device provided by the present invention, the annular mounting strip 3 includes multiple mounting rods 32 and connectors 33 for connecting adjacent mounting rods 32. When the annular mounting strip 3 is used to install and fix the lamp body 2 and the speaker body 1, the multiple mounting rods 32 are first distributed around the whole formed by the lamp body 2 and the speaker body 1, and then adjacent mounting rods 32 are connected by connectors 33, so that the mounting rods 32 are connected end to end, and finally the annular mounting strip 3 connects the lamp body 2 and the speaker body 1 into one unit. For example, when there are four mounting rods 32, the four mounting rods 32 are respectively distributed around the whole formed by the lamp body 2 and the speaker body 1, and then adjacent mounting rods 32 are connected by connectors 33. Before the connector 33 connects adjacent mounting rods 32, the first flange 11 on the speaker body 1 and the second flange 21 on the lamp body 2 can be inserted into the mounting groove 31 on the mounting rod 32, so that the mounting rod 32 is fitted onto the first flange 11 and the second flange 21. The operator can conveniently connect adjacent mounting rods 32 using the connector 33.

[0060] This invention also proposes an audio-visual lighting system, including the aforementioned audio-visual lighting device and a wireless microphone adapted to a wireless receiver of the audio-visual lighting device. Users can transmit sound signals to the wireless receiver within a certain range using the wireless microphone.
