The application provides a light-emitting device which can be applied to terminal equipment. The terminal device may be a sound box, or may be a vehicle, and the application is not limited to the type of the terminal device.

Referring to fig. 1 to 6, in an embodiment of the application, a light emitting device 100 includes a mesh enclosure 10, a speaker 20, and a light emitting module 30. The screen 10 is provided with a plurality of meshes 11, the loudspeaker 20 is arranged on one side of the screen 10, the light-emitting module 30 is arranged on one side of the screen 10 facing the loudspeaker 20, the light-emitting module 30 comprises a first light source 311 and a light guide member 33, light rays emitted by the first light source 311 can be transmitted to the light guide member 33, the screen 10 and the loudspeaker 20 are enclosed to form a front sound cavity 21, and at least part of the meshes 11 are communicated with the front sound cavity 21.

The mesh enclosure 10 may be used to cover the sound-producing side of the speaker 20 (i.e., the side of the diaphragm 23 in the speaker 20) to protect the speaker 20. The mesh enclosure 10 may include only a main body plate, or may further include a side wall plate circumferentially disposed around the main body plate on the basis of including the main body plate. It can be seen that the present application is not limited to the type and shape of the mesh enclosure 10. The mesh 11 provided on the mesh enclosure 10 may be used for passing through the sound emitted by the speaker 20, or may be used for passing through the light emitted by the light emitting module 30. The mesh 11 may be any shape such as a circular hole, a square hole, or a rectangular hole, and the distribution mode may be a circumferential array mode, or a rectangular array mode, and the arrangement mode of the mesh 11 is not limited in the present application.

The speaker 20 may be used for vibration sound production, and since the operation principle of the speaker 20 is the prior art, the structure of the speaker 20 will not be described in detail here. Alternatively, the speaker 20 may be mounted to the mesh enclosure 10 with a connection as described below. Of course, the connection as described below may also be mounted on the light guide 33. Alternatively, the device may be mounted on another object in a connecting manner. For example, when the light emitting device 100 is applied to a terminal apparatus, the speaker 20 may be connected to a certain component of the terminal apparatus. It can be seen that the present application is not limited to the connection installation object of the speaker 20, and it is only required to be disposed at one side of the mesh enclosure 10. The speaker 20 may be a tweeter, a midrange speaker, or a woofer, and the type of the speaker 20 is not limited in the present application.

The light emitting module 30 can emit light through the first light source 31. The light emitted by the first light source 31 may be transmitted only to the light guide 33. Of course, the light emitted by the first light source 31 may be partially transmitted to the light guide 33, and another portion may be transmitted to the side of the mesh enclosure 10 facing away from the speaker 20 through the mesh 11. It can be seen that the direction of the light emitting surface of the first light source 31 is not limited in the present application, and it is only necessary to ensure that at least light can be transmitted to the light guide 33. The number of the first light sources 31 may be one, or may be plural as described below, and the number of the first light sources 31 is not limited in the present application. In addition, the first light source 311 may be an LED lamp, so that the volume of the first light source 311 is relatively small, which is further beneficial to the integration and compactness of the light emitting device 100. Meanwhile, the first light source 311 can be made to save energy, so as to improve the environmental protection of the light emitting device 100 and further improve the user experience. Of course, in other embodiments, the first light source 311 may be an incandescent lamp, and the application is not limited to the type of the first light source 311. Further, the light emitting module 30 may conduct light through the light guide 33 to give a light effect at the light guide 33 while illuminating the sound emitting side of the speaker 20. In addition, the light guide member 33 can also enclose and form the front sound cavity 21 of the closed loudspeaker 20, so as to isolate the front sound cavity 21 and the rear sound cavity of the loudspeaker 20, avoid the air flow interference in the front sound cavity 21 and the rear sound cavity, and ensure that the loudspeaker 20 can normally sound. The light guide 33 may have a ring structure as described below, and may have an arc structure, which is not limited by the type of structure of the light guide 33. The material of the light guide 33 may be acrylic or polycarbonate (PC for short), and the material of the light guide 33 is not limited in the present application. The light emitting module 30 may be mounted on the mesh enclosure 10 in a connecting manner, or may be mounted on other objects, such as a mounting carrier 80 as described below, and the subject of the connection mounting of the light emitting module 30 is not limited in the present application.

When the light-emitting device 100 of the present application is used, the light-emitting effect of the first light source 311 in the light-emitting module 30 and the light guiding cooperation of the light guide member 33 enable the light-emitting device 100 to have a light effect and give visual experience to a user when in use, so as to realize the basic light effect function of the light-emitting device 100. Meanwhile, since the light emitting device 100 in this solution is further provided with the speaker 20, and the light guide member 33 in the light emitting module 30 encloses the mesh enclosure 10 and the speaker 20 to form the front sound cavity 21 of the speaker 20, it can be isolated from the rear sound cavity of the speaker 20, thereby meeting the normal use condition of the speaker 20, so as to realize that the light emitting device 100 further has a sound emitting function. It can be seen that the structural arrangement of the light-emitting device 100 in this embodiment gives the user visual experience, and further satisfies the normal use condition of the speaker 20, so that the user can give the user an auditory experience. Such a dual visual and audible experience is advantageous for improving the user experience of using the light emitting device 100. Furthermore, the light guide 33 of the light emitting module 30 may illuminate the sound side of the speaker 20 while giving a light effect. Therefore, the light effect of the light-emitting device 100 is also novel, which is beneficial to enhancing the ceremony feeling of the light-emitting device 100 when in use, so as to further improve the use experience of the user on the light-emitting device 100. In addition, the speaker 20 of the light emitting device 100 in this embodiment also uses the light guide member 33 in the light emitting module 30 to enclose the closed front sound cavity 21, so that the light guide member 33 has both the light guiding function and the sealing function. At this time, in other words, the same structure is adopted for conducting the light emitted from the first light source 311 and sealing the front sound chamber 21 of the speaker 20. Thus, the structural design of the light emitting device 100 can be simplified, thereby facilitating the manufacturing of the light emitting device 100. Meanwhile, since the simplification of the structure can also improve the degree of integration compactness of the light emitting device 100 to reduce the overall volume of the light emitting device 100, it is advantageous to improve the convenience of the subsequent installation thereof in a limited space.

Referring to fig. 3 to 6 in combination with fig. 8, in an embodiment of the application, the light guide 33 extends along the circumferential direction of the speaker 20 to form a ring structure, and the first light source 311 is disposed outside the light guide 33.

In the present embodiment, the light guide 33 is provided in a ring-shaped structure so that the light guide 33 can emit light at the circumferential direction of the speaker 20. Thus, the periphery of the light emitting side of the speaker 20 can be better illuminated, and a novel circle of halation effect surrounding the speaker 20 can be formed after the light is transmitted to the light guide 33 by the first light source 311, so that the light effect given by the light emitting module 30 is further improved, and the ceremony feel of the light emitting device 100 in use is enhanced. Meanwhile, the annular light guide 33 also facilitates the sealing effect on the front sound cavity 21 in the circumferential direction of the speaker 20, so that the structural arrangement of the speaker 20 can be simplified. The center line of the light guide 33 may coincide with the axis of the speaker 20, so as to improve the regularity of the light emitting apparatus 100 and enhance the aesthetic appearance of the subsequent lighting effect.

Referring to fig. 3 to 6 in combination with fig. 8, in an embodiment of the application, the number of the first light sources 311 is plural, and the plural first light sources 311 encircle the outer side of the front sound cavity 21.

In addition, the first light source 311 is disposed outside the front sound chamber 21, so that the space occupation of the front sound chamber 21 of the speaker 20 can be reduced. In the case where the light guide 33 has a ring structure as described above, it can be said that the plurality of first light sources 311 are disposed around the outside of the light guide 33. In addition, in other embodiments, the first light source 311 may be disposed in the front sound cavity 21.

In addition, at least the annular tube 331 of the light guide 33 encloses the mesh enclosure 10 and the speaker 20 to form the front sound chamber 21, that is, the annular tube 331 encloses the mesh enclosure 10 and the speaker 20 to form the front sound chamber 21, and of course, the annular plate 334, the annular tube 331, the mesh enclosure 10 and the speaker 20 may enclose the front sound chamber 21.

In the present embodiment, the light guide 33 is provided to include the annular cylinder 331 and the annular plate 334, so that the front sound cavity 21 of the speaker 20 can be formed conveniently by surrounding the mesh enclosure 10 and the speaker 20 through the annular cylinder 331, and the light effect of "halo" surrounding the speaker 20 is formed. And a connection position can be conveniently given through the annular plate 334 to realize connection installation of the light guide 33 and convenient contact with the speaker 20. Meanwhile, the light emitting surface of the first light source 311 may be installed toward the annular plate 334, or the light emitting surface of the first light source 311 may be installed toward the annular cylinder 331, thereby facilitating improvement of convenience in installation and setting of the first light source 311.
