Description

Technical Field

[0001] This utility model relates to a speaker, and more particularly to a speaker with a narrow-spacing uniform light structure. Background Technology

[0002] Speakers are common devices used in many households for playing audio. However, with the development of society, many speakers now have LED light strips added for aesthetic purposes, giving them lighting effects when they are working.

[0003] Because LED beads emit light with strong focusing, ordinary speakers will install a frosted lampshade in front of the LED light strip to achieve a softer lighting effect, thereby dispersing the light emitted by the LED beads to achieve a uniform and softer light. However, if a good uniform light effect is to be achieved, the distance between the frosted lampshade and the LED light strip cannot be too close, otherwise the uniform light effect will be reduced. Therefore, many other products need to increase the distance between the lampshade and the LED light strip to more than 20mm in order to achieve a uniform light effect. However, the space in the speaker is limited, so the above structure also limits the miniaturization design of the speaker. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a narrow-spacing uniform light structure for a speaker.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A narrow-pitch uniform light structure for a speaker includes an LED light strip and a lampshade. The LED light strip includes a circuit board and a plurality of LED chips disposed on the circuit board. The lampshade is characterized in that: a plurality of attenuation parts are provided on the lampshade, and part of the light emitted by the LED chips is emitted after shining on the corresponding attenuation parts.

[0007] The attenuation section is the area where paint is applied to the lampshade.

[0008] The area includes a central area and several surrounding areas arranged around the central area.

[0009] The central area is an inner circular spot, and the surrounding area includes several outer circular spots with a diameter smaller than the inner circular spot, which are evenly distributed around the inner circular spot.

[0010] The surrounding area also includes several distal circular spots with a diameter smaller than that of the outer circular spot, and the distal circular spots are evenly distributed around the outer circular spot.

[0011] It also includes a side cover, which has a mounting groove that runs through the side cover. The groove wall of the mounting groove has a slot, and the two sides of the circuit board are locked in the slot. The lampshade has a connecting part opposite to it. The connecting part is fixed to the side cover, thereby locking the circuit board in the slot so that it cannot be removed. The LED chip and the lampshade can both be exposed through the mounting groove.

[0012] The lampshade is equipped with a connecting plate.

[0013] A sealing cotton is provided between the lampshade and the side cover, and the connecting plate and the connecting part are in close contact with the sealing cotton to press it tightly onto the side cover.

[0014] The side cover is provided with a side baffle, which surrounds the LED light strip and the lampshade.

[0015] Both ends of the side cover are provided with end plates, and the iron mesh is fixed to the end plates.

[0016] The beneficial effects of this utility model are: This utility model has several attenuation parts on the lampshade. Some of the light emitted by the LED chip is emitted after shining on the corresponding attenuation part. The light emitted by the LED chip is attenuated by the attenuation part before being emitted, thereby achieving uniform light output. Therefore, the distance from the LED chip to the lampshade can be 2.77mm. This narrow-pitch uniform light structure can occupy a smaller volume on the speaker. Attached Figure Description

[0033] Reference Figure 1 and Figure 2This utility model discloses a narrow-pitch uniform light structure for a speaker, including an LED light strip 1 and a lampshade 2. The LED light strip 1 includes a circuit board 3 and several LED chips 4 disposed on the circuit board 3. The lampshade 2 is provided with several attenuation sections 5. Part of the light emitted by the LED chips 4 is emitted after illuminating the corresponding attenuation section 5. In this application, the attenuation section 5 is located in the central focusing area of ​​the corresponding LED chip 4. Because the light in this area is particularly bright compared to the surrounding area, it will create uneven light on the overall illumination surface. Therefore, the light in the central focusing area of ​​the LED chip 4 is attenuated by the attenuation section 5 and emitted, and its brightness is not much different from that of the surrounding area, thereby forming a uniform illumination surface and achieving better light efficiency.

[0034] As shown in the figure, the attenuation part 5 is the area where paint is applied to the lampshade 2. It is preferably white paint, and the paint type is DPU-W16D (semi-transparent white). The coating thickness is preferably 0.1mm. As a further preferred structure, the region includes a central region and several surrounding regions arranged around the central region. This forms an attenuation region corresponding to the illuminated area. Moreover, the central region and the surrounding regions are translucent, preventing excessive light attenuation and insufficient brightness. Specifically, the central region is an inner circular spot 51, and the surrounding regions include several outer circular spots 52 with diameters smaller than the inner circular spot 51. The outer circular spots 52 are evenly distributed around the inner circular spot 51. To further unify the illumination, the surrounding regions also include several far circular spots 53 with diameters smaller than the outer circular spots 52. The far circular spots 53 are evenly distributed around the outer circular spots 52, thus forming a three-layer surrounding region. The size of the circular spots corresponds to the light intensity of the region, thereby achieving uniform attenuation. Furthermore, there are gaps between the far circular spots 53 or the outer circular spots 52 that allow light to pass through, preventing excessive light attenuation and insufficient brightness.

[0035] It also includes a side cover 6, because the LED light strip 1 and lampshade 2 of this application are both installed inside the side cover 6. Both ends of the side cover 6 are provided with outwardly extending end plates 7. The iron mesh 8 is fixed on the end plates 7 to cover the outside of the side cover 6. Of course, the side cover 6 is equipped with a speaker and is decorated and protected by the iron mesh 8. The LED light strip 1 needs to emit light from the upper and lower ends of the side cover 6. The LED light strip 1 is set perpendicular to the side cover 6, and the illumination direction of the LED light strip 1 is parallel to the side cover 6 and the iron mesh 8. In this way, the light will not directly shine on the iron mesh 8 and thus directly shine into the eyes. Moreover, the iron mesh 8 diffuses the light, and the light will be more uniform. Therefore, this application adopts the following structure:

[0036] As shown in the figure, the side cover 6 is provided with a mounting groove 9 that is through the side cover 6. The groove wall of the mounting groove 9 is provided with a slot 10. The two sides of the circuit board 3 are locked in the slot 10. The lampshade 2 is provided with a connecting part 11 opposite to it. The connecting part 11 is fixed to the side cover 6, thereby locking the circuit board 3 in the slot 10 so that it cannot be removed. The LED chip 4 and the lampshade 2 can both be exposed through the mounting groove 9. Thus, the LED light strip 1 and the lampshade 2 can be installed on the side cover 6. After installation, the LED chip 4 can achieve a side-emitting effect. The installation structure is also simple.

[0037] As a further structural feature, the lampshade 2 is provided with a connecting plate 12, which is connected and fixed to the side cover 6 by screws. The lampshade 2 increases the fixing points through the above structure, thus avoiding problems such as deformation after installation.

[0038] As a further structural feature, a sealing cotton 13 is provided between the lampshade 2 and the side cover 6. The connecting plate 12 and the connecting part 11 are in close contact with the sealing cotton 13 and press it tightly onto the side cover 6. The sealing cotton 13 can ensure good sealing inside the side cover 6.

[0039] As shown in the figure, a side baffle 14 is provided on the outer side of the side cover 6. The side baffle 14 surrounds the LED light strip 1 and the lampshade 2. The side baffle 14 is composed of two mutually perpendicular pieces. The side baffle 14 can protect the LED light strip 1 and the lampshade 2 and hide the LED light strip 1 and the lampshade 2 for aesthetic purposes. In addition, the side baffle 14 can block light and prevent the light of the LED chip 4 from leaking out from there, thereby affecting the light efficiency. There is also a sealing cotton sheet 15 and a decorative cover 16 outside the side baffle 14.

[0040] The present invention provides a detailed description of a narrow-pitch uniform light structure for a speaker according to the embodiments of the present invention. Specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
