Description

Technical Field

[0001] This patent relates to the technical field of electroacoustic equipment, and specifically to a speaker with a luminous function. Background Art

[0002] Speakers are a type of sound amplification equipment widely used in various settings, including schools, large outdoor conferences, stages, square dances, and outdoor live broadcasts. Outdoor settings, such as square dancing and live broadcasts, place high demands not only on the acoustic performance of the speakers but also on their optical performance, aiming to create a superior visual experience through unique lighting effects. Therefore, many speaker products, while ensuring acoustic performance, also incorporate optical structures to provide users with a unique visual experience. Current speaker products employ LED lights as their optical structure, with one or more LEDs placed directly on the speaker. A single LED illuminates to create a bright spot, and multiple LEDs can be connected to form specific shapes, creating a specific optical effect when illuminated. Some speaker products also employ light strips bent into specific shapes to create a specific optical effect when illuminated. However, the light shape formed by a single LED is monotonous, and the use of multiple LEDs connected into a specific shape requires a large number of LED lamps. The solution of bending the light strip into a specific shape requires a long light strip and many LED lamps. Therefore, the cost of using LED lamps or light strips to produce optical effects on speakers is relatively high. For example, the patent document "CN202323607324.5-Portable Speaker" produces a specific optical effect by bending the light strip into a specific shape. However, there are technical problems such as the required light strip is long, the number of LED lamps is large, and the cost is high. Utility Model Content

[0022] See Figures 1 to 12, a speaker with a light-emitting function can achieve a special light-emitting visual effect while making sounds. The speaker with a light-emitting function includes a speaker shell 1 and a light-emitting device 2. The speaker shell 1 is the installation structure of the various functional components of the speaker. For example, the speaker, battery, handle, casters, etc. are all arranged on the speaker shell 1, so that the various functional components of the speaker are connected together through the speaker shell 1 to form an integral speaker. The light-emitting device 2 is also arranged on the speaker shell 1, and the light-emitting device 2 emits light toward the outside of the speaker shell 1. Therefore, when the speaker is working, the speaker completes the electroacoustic conversion and makes a sound toward the outside of the speaker, and the light-emitting device 2 realizes the electro-optical conversion and emits light outward, which can bring pleasant sound to the user as well as beautiful visual enjoyment, thereby making the speaker product more popular in the market.

[0023] See Figures 2 to 8 The light-emitting device 2 includes a lamp board 22, a reflective cup 23, a light guide plate 24, and a light-distributing plate 25. The lamp board 22, reflective cup 23, light guide plate 24, and light-distributing plate 25 are arranged on the speaker housing 1 in order from the inside to the outside. The lamp board 22 is provided with LED lamp beads 221. The LED lamp beads 221 on the lamp board 22 are electro-optical conversion components. When the LED lamp beads 221 on the lamp board 22 are powered, they emit light and provide light for the light-emitting device 2. The reflective cup 23 is a reflective component that reflects the light emitted by the LED lamp beads 221 on the lamp board 22 to the outside of the light-emitting device 2. The reflective cup 23 reflects the light emitted by the LED lamp beads 221 in a certain shape out of the light-emitting device 2, so that people around can see a special light shape, bringing a special visual experience. The reflective cup 23 in this embodiment is a ring-shaped structure, which can reflect the light emitted by the lamp board 22 in a ring shape out of the light-emitting device 2, so that people around can see the ring light shape. Through the above structure, in this embodiment, only a small number of LED lamp beads 221 or even one LED lamp bead 221 is needed to achieve a ring-shaped lighting effect. While realizing the acoustic and optical functions of the speaker, the cost of the speaker can be reduced and the market competitiveness of the speaker product can be improved.

[0024] See Figure 2 、 Figure 5 and Figures 9-12 The inner cross-section of the reflective cup 23 has a parabolic structure. This parabolic reflective structure can reflect more light emitted by the LED lamp beads 221 on the light board 22 away from the light-emitting device 2, thereby improving the luminous efficiency of the light-emitting device 2 and reducing the energy consumption of the speaker and the light-emitting device 2. To further improve the luminous efficiency of the speaker and the light-emitting device 2, it is best to provide a high-reflectivity reflective layer on the inner side of the reflective cup 23. High-reflectivity ink can be sprayed on the inner side of the reflective cup 23 as a reflective layer. This will reflect more light emitted by the LED lamp beads 221 on the light board 22 away from the light-emitting device 2, reducing the energy consumption of the light-emitting device 2 and the speaker, and reducing the cost of using the speaker.

[0025] See Figures 2 to 12 The reflective cup 23 can be set as a circular ring structure or a ring structure of other shapes. In this embodiment, the reflective cup 23 is set as a ring runway structure. A row of LED lamp beads 221 are provided on the light board 22. The light guide plate 24 and the light homogenizing plate 25 are also set as long structures matching the reflective cup 23. Therefore, the light emitted by the row of LED lamp beads 221 on the light board 22 is reflected forward by the reflective cup 23 with the ring runway shape to form a ring runway-shaped light-emitting structure. The speaker installed with the light-emitting device 2 also realizes the ring runway-shaped light-emitting structure, thereby bringing a special visual experience to the user, making the speaker product more popular in the market.

[0026] See Figure 4 The LED lamp beads 221 are preferably RGB three-color LEDs, that is, each LED lamp bead 221 has three chips of red, green and blue. The red, green and blue lights emitted by the three chips can be mixed to produce white light of different color temperatures of the product, or the red, green and blue chips can emit light separately to produce red, green or blue light, thereby enriching the color of the light emitted by the light-emitting device 2, further bringing a special visual experience to the user, and making the speaker product more popular in the market.

[0027] See Figure 4 The light board 22 also includes a PCB board 222, to which the LED lamp beads 221 are soldered. The PCB board 222 is provided to allow soldering of a row of LED lamp beads 221, facilitating the installation and fixation of multiple LED lamp beads 221. Wiring can be routed through the PCB board 222 to power each LED lamp bead 221. Furthermore, the PCB board 222 is coated with white highly reflective ink, thereby increasing its reflectivity and reflecting more light from each LED lamp bead 221 toward the reflective cup 23, thereby improving the luminous efficiency of the light-emitting device 2.

[0028] See Figure 6 and Figure 7The light guide plate 24 includes a first optical curved surface 241 and a second optical curved surface 242. The first optical curved surface 241 and the second optical curved surface 242 are arranged on opposite sides of the light guide plate 24. The first optical curved surface 241 and the second optical curved surface 242 are both structures that protrude outward, thereby optimizing the optical performance of the light guide plate 24, fully transmitting the light emitted by the lamp board 22 to the outside of the light-emitting device 2, and controlling the light shape of the light emitted by the light-emitting device 2 through the light guide plate 24. The light guide plate 24 can be made of a glass plate or a transparent acrylic plate. The outer side of the cross section of the first optical curved surface 241 and the second optical curved surface 242 are both structures formed by connecting multiple arcs. For example, in this embodiment, the outer side of the cross section of the first optical curved surface 241 is a structure formed by connecting two arcs, and the outer side of the cross section of the second optical curved surface 242 is a structure formed by connecting three arcs. By using different curved structures on the outer side of the cross section, the light shape of the light emitted by the light guide plate 24 can be controlled, thereby controlling the light shape of the light emitted by the light-emitting device 2.

[0029] See Figure 8 The light diffuser 25 is constructed of silicone with a light diffuser added to the silicone structure. It is best to use a skin-feeling silicone surface for the light diffuser 25. This skin-feeling silicone surface enhances the tactile experience, making the light diffuser 25 feel softer when the user touches the outside of the speaker. Furthermore, the light diffuser added to the silicone structure creates a softer lighting effect, making the light emitted by the light-emitting device 2 even softer.

[0030] See Figures 1 to 12 The light-emitting device 2 also includes a mounting frame 21, which is arranged on the speaker housing 1. It can be fixed to the speaker housing 1 by glue, screws, or snap-fit ​​to the housing 1 by a snap-fit ​​structure. The light board 22, reflective cup 23, light guide plate 24, and light diffuser 25 are all arranged on the mounting frame 21. The mounting frame 21 is provided with a mounting hole 211. The reflective cup 23 and light guide plate 24 are arranged in the mounting hole 211. The light board 22 and light diffuser 25 are arranged at opposite ends of the mounting hole 211. The mounting frame 21 is a two-layer structure, with the light guide plate 24 sandwiched between the upper and lower layers of the mounting frame 21. The reflective cup 23 is arranged in the mounting hole 211. The light board 22 is fixed to the mounting frame 21 by screws, and the reflective cup 23 is pressed onto the mounting frame 21. The light diffuser 25 is bonded to the outside of the mounting frame 21 and is flush with the outer surface of the housing 1.

[0031] See Figures 1 to 12During the production and assembly of the speaker of this embodiment, the light-emitting device 2 is first produced and assembled. The light guide plate 24 is first sandwiched between the upper and lower structures of the mounting frame 21. The reflector cup 23 is then installed inside the mounting hole 211, inside the light guide plate 24. The light panel 22 is screwed to the mounting frame 21, inside the reflector cup 23, and the reflector cup 23 is pressed against the mounting frame 21. Finally, the light-dispersing plate 25 is bonded to the outside of the mounting frame 21. After the light-emitting device 2 is assembled, the light-emitting device 2 is completely mounted on the housing 1, flush with the outer surface of the housing 1. In addition, the housing 1 needs to be equipped with components such as a speaker.

[0032] See Figures 1 to 12 When the speaker of this embodiment is working, the speaker completes the electroacoustic conversion and emits sound toward the outside of the speaker, and the light-emitting device 2 realizes the electro-optical conversion and emits light outward, which brings pleasant sound to the user as well as visual enjoyment.
