[0030] like Figure 1 As shown, the embodiment of the present invention discloses a lamp with a sound system, which has both lighting and sound playback functions. In addition to the floor lamp shown in the figure, the lamp with a sound system can also be a common lamp type such as a chandelier or a wall lamp, and can be installed in public places such as parks and entertainment venues, as well as private homes.

[0031] See also Figure 2 and Figure 3 The lamp with sound may include a lampshade 10, a radiator 11, a light source 12, a speaker 13 and a rear sound cavity 110; the radiator 11 is arranged inside the lampshade 10, and the interior of the radiator 11 is hollow; a plurality of the light sources 12 are arranged on the outside of the radiator 11; the speaker 13 is arranged at one end of the radiator 11, and the speaker 13 is connected to the interior of the radiator 11, so that the rear sound cavity 110 is formed inside the radiator 11.

[0032] Specifically, the lampshade 10 serves as a diffuser for the light emitted by the light source 12, helping to diffuse the light and adjusting the softness of the light by adjusting the light transmittance of the lampshade 10. Furthermore, the lampshade 10 protects the internal components. For example, when the lamp is installed outdoors, it can block rain and prevent damage to the internal electrical components. An opening is provided at one end of the lampshade 10 to accommodate the heat sink 11 and light source 12.

[0033] The light source 12 can be an LED light source 12, which can be attached to the radiator 11 through a substrate. The substrate can be set on multiple outer surfaces of the radiator 11, so that users located around the lamp can enjoy effective lighting. The radiator 11 is used to dissipate heat from the light source 12 to ensure the working reliability and service life of the light source 12. The material is preferably aluminum. The interior of the radiator 11 is hollow, and one end thereof has an opening. The speaker 13 is set at the end of the radiator 11 with the opening, so that the speaker 13 is connected to the interior of the radiator 11, and the internal space of the radiator 11 can serve as the rear sound cavity 110 of the speaker 13. In this way, the internal space of the radiator 11 is effectively utilized, so that the radiator 11 can not only dissipate heat for the light source 12, but also improve the acoustic effect. It is multi-purpose in one, thereby saving space in the lampshade 10, which can reduce the volume of the lamp body and save costs.

[0034] See also Figure 5 In some embodiments, the lamp with audio further includes a sound amplifier 14 and a front sound cavity 140. The sound amplifier 14 is arranged in a first direction of the speaker 13, and the radiator 11 is arranged in a second direction of the speaker 13. The first direction is opposite to the second direction. The first direction is the direction of the opening of the paper cone 131 of the speaker 13. The interior of the sound amplifier 14 is hollow to form the front sound cavity 140.

[0035] Specifically, the speaker 13 may be a cone-shaped speaker. The first direction of the speaker 13 is the direction in which the opening of the cone 131 of the cone-shaped speaker 13 faces, that is, the front of the cone 131. The second direction of the speaker 13 is the rear of the cone 131. The sound amplifier 14 is arranged in the first direction of the speaker 13 so that the sound emitted by the speaker 13 can be transmitted to the front sound cavity 140 and diffused to the outside of the lamp through the sound amplifier 14, allowing the user to hear the sound emitted by the lamp. The sound emitted by the lamp can be music or broadcast suitable for the corresponding setting scene. The front sound cavity 140 is located in front of the paper cone 131 of the speaker 13, and is mainly used to adjust the output of high-frequency sound; and the rear sound cavity 110, located behind the paper cone 131 of the conical speaker 13, is mainly used to enhance the output of low-frequency sound, prevent acoustic short circuit and correct low-frequency sound, making it more rounded and powerful, improving the strength and sound quality of the bass, and avoiding resonance, thereby avoiding resonance damage to the light source 12. In this way, the front sound cavity 140 and the rear sound cavity 110 work together to improve the sound playback effect of the lamp and provide users with a better user experience.

[0036] See also Figure 4 In some embodiments, the radiator 11 includes a cylindrical heat dissipation body 111 and a sound cavity cover 112 , the speaker 13 is arranged at one end of the heat dissipation body 111 , and the sound cavity cover 112 is tightly connected to the end of the heat dissipation body 111 away from the speaker 13 .

[0037] Specifically, the cylindrical heat dissipation body 111 can be a cylinder or a cylinder with a regular polygonal cross section. A plurality of light sources 12 are attached to the circumference or each side surface of the heat dissipation body 111 through a substrate. The plurality of light sources 12 are arranged around the axis of the heat dissipation body 111, so that the lamp can emit light in at least 360 degrees. When the lamp is a floor lamp, the lampshade 10 is longitudinally shaped, and the heat dissipation body 111 is arranged vertically, that is, the heat dissipation body 111 and the lampshade 10 are arranged coaxially, thereby maximizing the use of the space inside the lampshade 10, ensuring that the heat dissipation body 111 has enough area to set the light source 12, ensuring the light emission effect, and also improving the heat dissipation performance of the heat dissipation body 111. The speaker 13 is arranged at the bottom end of the heat dissipation body 111, and the sound cavity cover 112 is tightly connected to the top end of the speaker 13, thereby ensuring that the volume of the rear sound cavity 110 is large enough to avoid acoustic short circuit and resonance.

[0038] In some embodiments, the radiator 11 and the speaker 13 are coaxially arranged.

[0039] Specifically, the heat dissipation body 111 is coaxially arranged with the speaker 13 , that is, the rear sound cavity 110 is coaxially arranged with the speaker 13 , to ensure that the sound waves propagate regularly in the rear sound cavity 110 , thereby improving the strength and sound quality of the bass.

[0040] In some embodiments, the sound cavity cover 112 includes a planar cover body 1121 and a connecting section 1122, the planar cover body 1121 is arranged vertically to the heat dissipation body 111, the connecting section 1122 is arranged between the planar cover body 1121 and the heat dissipation body 111, and the connecting section 1122 is inclined relative to the planar cover body 1121 and the heat dissipation body 111.

[0041] Specifically, the connecting section 1122 is tilted relative to the planar cover 1121 and the heat dissipation body 111, that is, the connecting section 1122, the planar cover 1121, and the heat dissipation body 111 are not on the same plane. The heat dissipation body 111, the connecting section 1122, and the planar cover 1121 are all provided with multiple light sources 12, so that the light sources 12 of the lamp have more light emission directions, thereby improving the light emission effect of the lamp. The heat dissipation body 111, the connecting section 1122, and the planar cover 1121 can be fixedly connected by screws.

[0042] See also Figure 5 In some embodiments, the lamp with audio further includes an isolation plate 15, which is arranged between the front sound cavity 140 and the rear sound cavity 110 to isolate the front sound cavity 140 from the rear sound cavity 110; the speaker 13 is fixedly arranged on the isolation plate 15, and a through hole 150 is provided on the isolation plate 15 at a position opposite to the speaker 13, so that the sound of the speaker 13 can be transmitted to the front sound cavity 140.

[0043] Specifically, the isolation plate 15 can be fixed to the end of the heat dissipation body 111 close to the speaker 13 by screws, and the diameter of the isolation plate 15 is larger than the diameter of the heat dissipation body 111, so that the edge of the isolation plate 15 protrudes from the edge of the heat dissipation body 111, thereby closing the open end of the radiator 11, preventing the interior of the radiator 11, that is, the sound waves in the rear sound cavity 110 from diffusing into the lampshade 10, and the edge of the isolation plate 15 is tightly connected to the inner wall of the lampshade 10, preventing the sound of the front sound cavity 140 from diffusing into the lampshade 10. The speaker 13 can be fixed to the isolation plate 15 by screws, and the paper cone 131 on the speaker 13 is arranged relative to the speaker 13, so that the sound generated by the speaker 13 can be more completely transmitted to the front sound cavity 140.

[0044] In some embodiments, one end of the sound amplifying portion 14 is connected to the isolation plate 15 , and a cross-sectional dimension of the sound amplifying portion 14 gradually decreases from an end close to the isolation plate 15 to an end away from the isolation plate 15 .

[0045] Specifically, the heat dissipation body 111 is connected to the upper end surface of the isolation plate 15, one end of the sound amplifier 14 is connected to the side edge of the isolation plate 15, and the cross-sectional size of the sound amplifier 14 gradually decreases from the end close to the isolation plate 15 to the end away from the isolation plate 15, that is, the sound amplifier 14 is cylindrical in shape, the diameter of which gradually decreases from the end close to the speaker 13 to the end away from the speaker 13, so that the diameter of the front sound cavity 140 gradually decreases from the end close to the speaker 13 to the end away from the speaker 13. The front sound cavity 140 of this shape can improve the frequency response and noise control of the sound, and can also enhance the overall sound expression, thereby enhancing the user's listening experience.

[0046] In some embodiments, the sound amplifying portion 14 is provided with a plurality of sound holes 141, which are arranged in a ring around the central axis of the sound amplifying portion 14. This allows the sound in the front sound cavity 140 to diffuse in all directions from the sound amplifying portion 14, thereby enhancing the user's auditory experience.

[0047] See also Figure 5 In some embodiments, the lamp with audio further includes a control panel 161, which is disposed in the sound amplifying portion 14 and at an end of the sound amplifying portion 14 away from the sound insulation board, and is electrically connected to the light source 12 and the speaker 13.

[0048] Specifically, the audio-equipped lamp also includes a control component 16, which includes a control panel 161. This control panel 161 can communicate with a user's mobile terminal, which can be a smart device such as a mobile phone, tablet computer, or smartwatch. The user can send instructions to the control panel 161 via the mobile terminal to control the light source 12 and speaker 13, thereby achieving intelligent control of the audio-equipped lamp and improving the user experience. For example, the user can adjust the lighting effect, sound type, and volume of the audio-equipped lamp as needed.

[0049] The control assembly 16 may also include a microphone 162 and a sensor switch 163. The microphone 162 is electrically connected to the control board 161 and can be used to receive the user's voice control instructions, so that the user can directly control the lamp with audio by voice in addition to being able to control it through a mobile terminal, thereby meeting the usage needs of different users. For example, older users who are not proficient in using mobile terminals can use voice control. For example, when the user's mobile terminal is not nearby, voice control can be used to avoid having to search for the mobile terminal and affecting their usage experience.

[0050] The sensor switch 163 is electrically connected to the control board 161. The sensor switch 163 can be an optical sensor switch. The sensor switch 163 can control the lamp according to the brightness of the external environment of the lamp. For example, when the lamp with sound is set in a park, it can be turned on at night and the speaker 13 can be controlled to play soothing music. The sensor switch 163 can also be a balance sensor switch. For example, when the lamp with sound falls to the ground due to an accident, the sensor switch 163 controls the lamp to turn off. When the lamp returns to its normal state, the sensor switch 163 controls the lamp to turn on, ensuring safety in use.

[0051] In some embodiments, the lamp with audio further includes a sound cone 17 , which is disposed between the control panel 161 and the isolation panel 15 , with the tip of the sound cone 17 facing the speaker 13 .

[0052] Specifically, the sound cone 17 is positioned within the front sound cavity 140, specifically between the control panel 161 and the isolation panel 15. The tip of the sound cone 17 faces the speaker 13, and the sound cone 17, front sound cavity 140, speaker 13, and rear sound cavity 110 are coaxially arranged. The sound cone 17 effectively eliminates resonance caused by sound within the front sound cavity 140, improving sound quality. It also prevents resonance from affecting the performance of the control panel 161, ensuring that the sound playback function of the speaker-equipped lamp does not adversely affect its lighting function.

[0053] In some embodiments, the speaker-equipped lamp may further include a fixing plate 18. This fixing plate 18 is positioned at the end of the sound amplifier 14 away from the sound insulation board, between the control board 161 and the end of the sound amplifier 14. This fixing plate 18 is used to secure the control board 161 and the sound cone 17 to the end of the sound amplifier 14 away from the sound insulation board, ensuring stable and safe operation. Specifically, the sound cone 17, control board 161, fixing plate 18, and the end of the sound amplifier 14 are secured together using screws and nuts.

[0054] See also Figure 6In some embodiments, the sound-equipped lamp further comprises a connecting member 19 for cooperating with the external environment to keep the shape of the lamp in a normal working shape, for example, when the sound-equipped lamp is a floor lamp, the connecting member 19 is a connecting rod, one end of the connecting rod is connected with the end of the sound amplification part 14, and the other end of the connecting rod is connected with the base, so that the sound-equipped lamp can be vertically supported on the ground. The connecting rod is hollow inside, and the induction switch 163 can be arranged in the internal space at the top end of the connecting rod. In this embodiment, the induction switch 163 can be a push type or touch type switch, which is connected with the button 21 or the display screen on the outer side surface of the connecting rod, and the user can control the lamp by pressing or touching. The internal space in the middle of the connecting rod can be used as a wiring channel for arranging the connecting line of the external electrical connection, and the base is provided with a port connected with the connecting line, which can be used for charging the sound-equipped lamp or performing wired control.

[0055] For another example, when the sound-equipped lamp is a ceiling lamp, the connecting member 19 can be a hanging rope, which is connected with the end of the sound amplification part 14 and a hook on the ceiling, so that the sound-equipped lamp can be hung on the ceiling.

[0056] In some embodiments, the sound-equipped lamp further comprises a decorative ring 20, which can be arranged at the part where the lampshade 10 is connected with the sound amplification part 14 and the part where the sound amplification part 14 is connected with the connecting rod, so as to make the outer surface of the connecting part smoother and improve the visual experience of the user.

[0057] In summary, the sound-equipped lamp provided by the utility model has at least the following beneficial effects:

[0058] The lamp has sound and is matched with different lighting and music modes, and is matched with various control modes, such as mobile terminal control, voice control and wired control.

[0059] The rear sound cavity effectively utilizes the internal space of the lamp, achieves the audio effect, does not produce resonance and reduces the product cost.

[0060] The above is only a specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, and anyone skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the utility model, and these modifications or replacements should be covered in the protection scope of the utility model.
