[0002] With the improvement of people's living standards, camping has become one of the ways of outdoor leisure activities for most people nowadays. The application of outdoor speakers in camping equipment has correspondingly enhanced the camping experience. Current outdoor speakers are deeply loved by outdoor enthusiasts, mountaineering enthusiasts or adventure enthusiasts because they are equipped with Bluetooth chips or wireless communication modules to replace traditional wire connections. Existing outdoor speakers generally include a hollow-structured housing and a panel covering the housing. The panel is detachably fastened to the housing. A sound-emitting device is provided inside the housing, and control keys for controlling the sound-emitting device are provided on the side wall of the panel or the housing. Such outdoor speakers only have a sound-emitting effect when used outdoors and cannot emit light, which is inconvenient to use at night and it is impossible to clearly operate the control keys of the outdoor speaker.

[0003] In view of this, the inventor of this case has conducted in-depth research on the above problems, and thus this case has been created. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a light-emitting panel for a speaker that facilitates the use of the outdoor speaker at night.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A light-emitting panel for a speaker includes a panel body. The panel body has a cover plate and a side surround disposed along the circumference of the cover plate and forming a closed-ring structure at the bottom surface of the cover plate. The cover plate is an opaque injection-molded panel, and the side surround is a semi-transparent light guide plate. A closed-ring space with an open bottom surface is formed between the bottom surface of the cover plate and the side surround. A light-emitting circuit board is installed in the closed-ring space. A light-emitting component with its light-emitting surface facing down is installed on the bottom surface of the light-emitting circuit board. A light-transmitting area for displaying a LOGO is provided in a partial area of the cover plate. A microphone hole is provided in the cover plate outside the light-transmitting area. A light-blocking structure is provided on the bottom surface of the cover plate outside the light-transmitting area, and the light-blocking structure is located between the light-transmitting area and the light-blocking structure.

[0007] Four positioning card columns distributed at the four corners of the closed-ring space are integrally formed on the bottom surface of the cover plate within the closed-ring space. Through holes for the positioning card columns to tightly pass through are respectively provided at the four corners of the light-emitting circuit board. A plurality of the light-emitting components are installed along the length direction of the side of the light-emitting circuit board at intervals and in a surrounding manner on the four side edges of the bottom surface of the light-emitting circuit board.

[0008] The light-emitting component is an LED lamp.

[0009] A closed annular groove is recessed in the central area of the above-mentioned cover plate. A light-transmitting light guide ring with its lower end extending downward out of the closed annular groove is embedded in this closed annular groove. The above-mentioned light-transmitting area is within the range of the light-transmitting light guide ring. A broken light ring in a closed annular structure protrudes downward from the lower bottom surface of the above-mentioned cover plate. The above-mentioned light-transmitting light guide ring is within the range of the broken light ring. An annular accommodating space is formed between the closed annular groove and the broken light ring on the above-mentioned cover plate. A light-shielding cotton is embedded in this annular accommodating space. The lower end of the above-mentioned light-transmitting light guide ring protrudes from the light-shielding cotton. The light-shielding cotton and the broken light ring constitute the described light-breaking structure.

[0010] The above-mentioned light-shielding cotton is a black sponge block. A plurality of positioning columns are protruded on the surface of the broken light ring facing the light-transmitting light guide ring and are distributed at intervals around the circumference.

[0011] A plurality of depressions are recessed on the lower bottom surface of the above-mentioned cover body outside the broken light ring and are distributed at intervals around the circumference.

The clamping strips are square blocks. The lower bottom surface of the clamping strips is an inclined surface that slopes upward. The inclined surfaces of each clamping strip enclose a horn-shaped space that gradually expands from bottom to top.

[0013] After adopting the above technical solution, for a light-emitting panel of a loudspeaker of the present utility model, when applied, the on-off of the light-emitting circuit and the sound-emitting device of the loudspeaker share a power supply. In this way, when the sound-emitting device is turned on, the light-emitting circuit is correspondingly turned on. At this time, the light-emitting circuit controls the light-emitting component to emit light. The light emitted by the light-emitting component passes through the semi-transparent light guide ring. That is, there is a ring of light on the side surface of the panel. In this way, the light transmitted by the panel is relatively soft and not easy to be dazzling, increasing the interest of the loudspeaker. Moreover, the light can be transmitted through the light-transmitting area, enabling the LOGO of the loudspeaker to be clearly presented, playing a decorative role. Finally, the light-breaking structure is used to prevent the light from passing through the microphone hole, making the light-emitting area of the entire panel uniform. Description of the Drawings

[0017] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail with reference to the drawings.

[0018] A light-emitting panel of a loudspeaker of the present utility model, as Figures 1 - 3As shown in the figure, it includes a panel body 1. The panel body 1 is square. The panel body 1 has a cover plate 11 and a side surround 12 which is located on the bottom surface of the cover plate 11 and is arranged in a closed annular structure along the circumferential direction of the cover plate 11. The cover plate 11 is an opaque injection-molded panel, and the opaque injection-molded panel is a black panel. The side surround 12 is a semi-transparent light guide plate, and this semi-transparent light guide plate is a PMMA plate. The semi-transparent light guide plate and the cover plate 11 are fixedly adhered together by thermosetting glue. The bottom surface of the cover plate 1 and the side surround 12 enclose a closed annular space with an open bottom. Preferably, the closed annular space is a horn-shaped space that gradually tapers from top to bottom.

[0019] A light-emitting circuit board (not shown in the figure) is installed in the closed annular space. Specifically, four positioning posts 111 are integrally formed on the bottom surface of the cover plate 11 in the closed annular space and are distributed at the four corners of the closed annular space. Through holes for the positioning posts 111 to tightly pass through are respectively opened at the four corners of the light-emitting circuit board. The fixed installation of the light-emitting circuit board is realized by the tight fit of the positioning posts and the through holes.

[0020] A light-emitting component with its light-emitting surface facing down is installed on the bottom surface of the light-emitting circuit board. The light-emitting component is an LED lamp. Specifically, several LED lamps are installed at the four side edges of the bottom surface of the light-emitting circuit board and are spaced and distributed around along the length direction of the side of the light-emitting circuit board. This LED lamp is a three-color LED lamp. There is a control chip on the light-emitting circuit board to control the operation of the three-color LED lamp. During application, the three-color LED lamp will continuously switch colors, so that the speaker emits red light, blue light and green light, thereby making the appearance of the speaker more beautiful. Coupled with the music of the speaker, the whole speaker has better interest. In this new type, the light-emitting circuit board can share the same power supply and the same control switch with the sound-emitting device of the speaker. In addition, the control principle of the light-emitting circuit in this new type is well-known.

[0021] A light-transmitting area 112 for displaying the LOGO is provided in a partial area of the cover plate 11. Preferably, the light-transmitting area 112 is arranged in the middle of the cover plate 11. The light-transmitting area 112 is circular. A non-light-transmitting LOGO area is arranged in the middle area of the circle. The LOGO is printed in this non-light-transmitting LOGO area. During processing, a layer of black ink is printed on the surface of the cover body, and the middle area of the cover body does not need to be printed with black ink. This area without black ink is the light-transmitting area 112. Then, a layer of black ink is also printed in the area of the light-transmitting area 112 to form the non-light-transmitting LOGO area, that is, a layer of black ink layer is printed on the surface of the cover plate, and a non-black ink layer circle is processed in the central area. This non-black ink layer circle area is the light-transmitting area. In this new type, in order to enhance the light brightness of the light-transmitting area 112, through holes can be opened in the light-emitting circuit board at the position corresponding to the light-transmitting area, so that the light of the LED lamp on the bottom surface of the light-emitting circuit board can uniformly penetrate through the through holes to the light-transmitting area 112, or an LED lamp can be installed on the upper surface of the light-emitting circuit board corresponding to the light-transmitting area 112.

[0022] The cover plate 1 is provided with a microphone hole 113 outside the light-transmitting area 112. The bottom surface of the cover plate 1 is provided with a light-blocking structure outside the light-transmitting area 112, and the light-blocking structure is located between the light-transmitting area and the microphone hole 12. Specifically, a closed annular groove 114 is recessed in the central area of the cover plate 1, and a light-transmitting light guide ring (not shown in the figure) with its lower end extending downward outside the closed annular groove is embedded in this closed annular groove 114. The light-transmitting area 112 is within the range of the light-transmitting light guide ring. The lower bottom surface of the cover plate 1 protrudes downward to form a closed annular light-blocking ring 115. The light-transmitting light guide ring is within the range of the light-blocking ring 115, that is, the closed annular groove and the light-blocking ring are arranged in an inner and outer ring matching manner. An annular accommodating space 100 is formed between the cover plate 1 in the closed annular groove and the light-blocking ring, and a light-shielding cotton (not shown in the figure) is embedded in this annular accommodating space. The light-shielding cotton is a black sponge block. The lower end of the light-transmitting light guide ring protrudes out of the closed annular groove and is in close contact with the upper surface of the light-emitting circuit board. The light-transmitting light guide ring coincides with the non-black ink layer circle. The light-shielding cotton and the light-blocking ring constitute the light-blocking structure. In this new type, four microphone holes 113 can be provided, and the four microphone holes are arranged in a circular pattern around the outside of the light-blocking ring 115. In addition, in order to ensure the volume, the cover plate is recessed at the position of the microphone hole, and the microphone hole 113 is located in the central area of this recess, so that the microphone hole 113 is not easily blocked by internal parts.

[0023] For an illuminating panel of a loudspeaker of the present utility model, when the control switch of the loudspeaker is turned on during application, the sound-emitting device of the loudspeaker is activated, and at the same time the lighting circuit is activated. Each LED lamp emits light and operates in three colors. The light emitted by the LED lamp is transmitted through the part of the semi-transparent light guide ring below the light-emitting circuit board, that is, there is a ring of light around the side wall of the panel. Since the light of the LED is transmitted from the side, the light transmitted through the panel is relatively soft and not easy to glare, increasing the interest of the loudspeaker. Moreover, the light can be transmitted through the light-transmitting area 112, so that the LOGO inside the light-transmitting area 112 can be clearly presented, playing a decorative role. Finally, the light-shielding cotton is used to prevent the light at the light-shielding area 112 from being transmitted through the microphone hole, making the front surface of the entire panel emit light evenly.

[0024] In this new type, the positioning stud 111 is cylindrical, and several clamping strips 1111 are protruded on the outer side wall of the positioning stud 111 and are distributed in a circumferential interval. The clamping strips 1111 are square blocks, and the lower bottom surface of the clamping strip 1111 is an inclined surface that slopes upward. The inclined surfaces of each clamping strip surround a horn space that gradually expands from bottom to top. Using each clamping strip makes the installation of the light-emitting circuit board more compact, and the inclined surfaces can play a guiding role in clamping the light-emitting circuit board into the positioning stud.

[0025] In this new type, several positioning posts 116 are protruded on the surface of the light-blocking ring facing the light-transmitting light guide ring and are distributed in a circumferential interval. The positioning posts 116 can be used to be fastened together with the housing of the loudspeaker, enhancing the installation stability of the panel.

[0026] In this new type, in order to ensure the light-emitting area on the side, the size of the light-emitting circuit board is preferably smaller than the size of the side surround, and there is a light path spacing between the outer side wall of the light-emitting circuit board and the side surround.

[0027] The product form of the present utility model is not limited to the illustrations and embodiments in this case. Any person making appropriate changes or modifications with a similar idea should be regarded as not departing from the patent scope of the present utility model.
