The following description of the embodiments with reference to the accompanying drawings is illustrative and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] like Figure 1-Figure 3 As shown, the utility model is a portable sound-absorbing decorative lamp, comprising a light box frame 1, a sound-absorbing panel 2 mounted thereon, a lampshade 3, a light source 4, and a power control box 5. The power control box 5 is connected to and controls the light source 4. The sound-absorbing panel 2 is disposed outside the lampshade 3 and is connected to the light box frame 1 to form a cavity. The lampshade 3 encloses the light source 4 within the light box frame 1. The sound-absorbing panel 2 is a flexible porous plate having decorative holes 2-1 forming an artistic pattern, which serves a decorative purpose while allowing sound to enter the cavity. Noise is continuously reflected, scattered, and rubbed within the pores and fibers of the sound-absorbing panel through the cavity, resulting in continuous energy loss and achieving excellent sound absorption. The sound-absorbing panel 2 is a polyester fiberboard, but can also be replaced with other materials, such as glass fiber or a mixture of glass fiber and polyester fiber.

[0026] Furthermore, the lampshade 3 includes a front light-transmitting plate 3-1 and a rear light-transmitting plate 3-2, and the light source 4 is a light strip. The front light-transmitting plate and the rear light-transmitting plate are respectively arranged on the front and rear sides of the light strip. There is a gap between the front light-transmitting plate and the rear light-transmitting plate to form a light source diffusion cavity. The light emitted by the light strip radiates outward through the front light-transmitting plate and the rear light-transmitting plate, providing good lighting and decorative effects. The front light-transmitting plate 3-1 and the rear light-transmitting plate 3-2 are made of one of PMMA, PC, PE, and PP boards. The light strip is a flexible LED light strip. The LED light strip is arranged along the inner wall of the light box frame and can be fixed by adhesive or screws. The LED light strip is ring-shaped and arranged above the power control box. The power control box 5 is arranged at the lower part of the light box frame. The sound-absorbing panel 2 is provided with a control switch 5-1 electrically connected to the power control box. The control switch is a push switch, a touch switch, or a light-sensing switch. The power control box 5 houses a battery and corresponding charging circuit, making the lamp portable and flexible while simultaneously addressing lighting, decorative, and sound absorption requirements. It effectively utilizes limited space to meet diverse quality-of-life needs while also achieving both aesthetics and practicality. The charging circuit utilizes a conventional circuit, as shown in the figure. When the power is applied, the 220V AC voltage is stepped down and limited by capacitor C1, rectified by a bridge rectifier, and filtered by capacitor C2. This generates a DC voltage that charges the battery through diode VD. The battery charging current is primarily determined by capacitor C1. LED 1 serves as a charging indicator, and resistor R1 serves as a bleeder resistor. LEDs LEDs 2 through 20 (not all shown) are connected in parallel, each with a current-limiting SMD resistor. K represents the lamp's power switch. Turning K on illuminates LEDs LEDs 2 through 20. The rectifier bridge in the circuit typically uses a SMD package, with MB6S and DB107S being common models. It should be noted that the implementation scheme of the charging circuit is not limited thereto, and other circuit designs may be performed as needed.

[0027] Compared with the existing technology, the present invention adopts a sound-absorbing material that is an elastic porous material, including one or more of glass fiber and polyester fiber. The lampshade is a light-transmitting material, including one of PMMA, PC, PE, and PP. The light strip is a flexible LED light strip, and the lamp shell has decorative holes with different artistic patterns, which not only plays a decorative role but also allows sound to enter the internal cavity of the lamp. A cavity is formed inside the lamp, and the noise enters the pores and fibers of the sound-absorbing material through the cavity. The noise is constantly reflected, scattered and rubbed in the pores and fibers, and energy is constantly lost, which has a good sound absorption effect. The lamp adopts a rechargeable lamp, which makes the lamp portable and flexible. It solves the requirements of lighting, decoration, and sound absorption at the same time. It effectively utilizes limited space to meet various needs for quality of life, and has both aesthetics and practicality.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
