[0029] It should be further understood that the terms "and, or" used in the present description and the appended claims refer to and include any and all possible combinations of one or more of the associated listed items.

[0030] like Figure 1 As shown, the embodiment of the present invention discloses a lamp with a sound system, which has the function of lighting and the function of playing sound. 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 and a wall lamp, which can be installed in public places such as parks and entertainment venues, and can also be installed in private homes.

[0031] Read also Figure 2 and Figure 3 The lamp with audio 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 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, which helps diffuse the light and can change the softness of the light by adjusting the light transmittance of the lampshade 10; on the other hand, the lampshade 10 also protects the internal components. For example, when the lamp is set in an open-air place, it can block rain and prevent the internal electrical components from being damaged. An opening is provided at one end of the lampshade 10 to accommodate the heat sink 11 and the light source 12 therein.

[0033] The light source 12 may be an LED light source 12, which may be attached to the radiator 11 through a substrate. The substrate may be arranged 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, and its material is preferably aluminum. The interior of the radiator 11 is hollow, and one end thereof has an opening. The speaker 13 is arranged 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 play the role of dissipating heat for the light source 12, but also play the role of improving the acoustic effect. It is multi-purpose in one body, thereby saving space in the lampshade 10, which can reduce the volume of the lamp body and save costs.

[0034] Read 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 speaker, and the first direction of the speaker 13 is the direction in which the opening of the cone 131 of the cone speaker 13 faces, that is, the front of the cone 131, and 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 propagated into the front sound cavity 140, and diffused to the outside of the lamp through the sound amplifier 14, so that the user can hear the sound emitted by the lamp, and 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 sounds; 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 sounds, prevent acoustic short circuits, and correct low-frequency sounds to make them more rounded and powerful, thereby enhancing the strength and sound quality of the bass and avoiding resonance, thereby avoiding resonance from damaging the light source 12. In this way, the front sound cavity 140 and the rear sound cavity 110 work together to improve the audio playback effect of the lamp and provide users with a better user experience.

[0036] Read 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 an 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 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 at least 360 degrees. When the lamp is a floor lamp, the lampshade 10 is longitudinally long, and the heat dissipation body 111 is arranged vertically, that is, the heat dissipation body 111 and the lampshade 10 are arranged coaxially, so as to maximize the use of the space in the lampshade 10, ensure that the heat dissipation body 111 has enough area to set the light source 12, ensure the light emission effect, and also improve 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, so as to ensure 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 , so as 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 vertically arranged with respect 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 plane cover 1121 and the heat dissipation body 111, that is, the connecting section 1122, the plane cover 1121 and the heat dissipation body 111 are not on the same plane, and the heat dissipation body 111, the connecting section 1122 and the plane cover 1121 are all provided with a plurality of light sources 12, so that the light source 12 of the lamp has more light emitting directions, thereby improving the light emitting effect of the lamp. The heat dissipation body 111, the connecting section 1122 and the plane 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 disposed 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 disposed 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 to allow the sound of the speaker 13 to be transmitted to the front sound cavity 140.

[0043] Specifically, the isolation plate 15 can be fixed to one 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 to prevent 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 to prevent 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 auditory experience.

[0046] In some embodiments, the sound amplifier 14 is provided with a plurality of sound holes 141, and the sound holes 141 are arranged in a ring shape around the central axis of the sound amplifier 14. Thus, the sound in the front sound cavity 140 can be diffused from all directions of the sound amplifier 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 amplifier 14, and the control panel 161 is disposed at one end of the sound amplifier 14 away from the sound insulation board, and the control panel 161 is electrically connected to the light source 12 and the speaker 13.

[0048] Specifically, the lamp with audio also includes a control component 16, which includes a control panel 161. The control panel 161 can communicate with the user's mobile terminal, which can be a smart device such as a mobile phone, a tablet computer, a smart watch, etc. The user can send instructions to the control panel 161 through the mobile terminal to control the light source 12 and the speaker 13 to achieve intelligent control of the lamp with audio and improve the user's experience. For example, the user can adjust the light effect, sound type, sound volume, etc. of the lamp with audio as needed.

[0049] The control component 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 command, so that the user can directly control the lamp with audio by voice on the basis of being able to control it with a mobile terminal, so as to meet the use needs of different users. For example, older users who are not proficient in using mobile terminals can use voice control. For another example, when the user's mobile terminal is not around, voice control can also be used to avoid looking for the mobile terminal everywhere, affecting their use experience.

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

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

[0052] Specifically, the sound cone 17 is disposed in the front sound cavity 140, specifically between the control board 161 and the isolation board 15, the cone tip of the sound cone 17 is disposed toward the speaker 13, and the sound cone 17, the front sound cavity 140, the speaker 13 and the rear sound cavity 110 are coaxially disposed. The sound cone 17 can effectively eliminate the resonance caused by the sound in the front sound cavity 140 to improve the sound quality, and can prevent the resonance from affecting the working performance of the control board 161, ensuring that the sound playback function of the lamp with audio does not have an adverse effect on its lighting function.

[0053] In some embodiments, the lamp with audio may further include a fixing plate 18. The fixing plate 18 is disposed at one end of the sound amplifier 14 away from the sound insulation board and is located between the control board 161 and the end of the sound amplifier 14. The fixing plate 18 is used to fix the control board 161 and the sound cone 17 to the end of the sound amplifier 14 away from the sound insulation board to ensure stable and safe operation. Specifically, the sound cone 17, the control board 161, the fixing plate 18, and the end of the sound amplifier 14 may be fixedly connected by screws and nuts.

[0054] Read also Figure 6In some embodiments, the lamp with audio may further include a connector 19, which is used to cooperate with the external environment to keep the shape of the lamp in a normal working shape. For example, when the lamp with audio is a floor lamp, the connector 19 is a connecting rod, one end of which is connected to the end of the sound amplifier 14, and the other end of the connecting rod is connected to the base, so that the lamp with audio can be vertically supported on the ground. The interior of the connecting rod is hollow, and the induction switch 163 can be set in the internal space at the top of the connecting rod. In this embodiment, the induction switch 163 can be a push-type or touch-type switch, which is connected to the button 21 or the display screen on the outer side of the connecting rod. 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 setting a connecting wire for external electrical connection. The base is provided with a port connected to the connecting wire, which can be used to charge the lamp with audio or perform wired control.

[0055] For another example, when the lamp with audio is a chandelier, the connecting member 19 may be a hanging rope, which connects the end of the sound amplifier 14 and a hook on the ceiling, so that the lamp with audio can be hung on the ceiling.

[0056] In some embodiments, the lamp with audio may further include a decorative ring 20, which may be disposed at the portion where the lampshade 10 is connected to the sound amplifier 14 and at the portion where the sound amplifier 14 is connected to the connecting rod, so as to make the outer surface of the connecting portion smoother and enhance the user's visual experience.

[0057] In summary, the lamp with sound provided by the present invention has at least the following beneficial effects:

[0058] The lamps are equipped with speakers and different lighting and music modes, and multiple control modes, such as mobile terminal control, voice control, wired control, etc.

[0059] The rear sound cavity effectively utilizes the internal space of the lamp, achieving audio effects without resonance and reducing product costs.

[0060] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.
