For ease of installation, a mounting bracket is installed on the outer wall of the frame, and the ambient lighting strip is then fixed to the bracket. The frame has perforations to allow light from the light strip to pass through and project onto the cone, which is made of a translucent material, allowing users to view the lighting effects through the cone.

[0003] The speaker in the related technology has the following shortcomings: because the frame blocks the light from the light strip, the light from the light strip cannot be evenly projected onto the entire area of ​​the cone, resulting in shadows on the cone and affecting the final light effect. Utility Model Content

[0004] The purpose of this invention is to provide a light-emitting speaker that avoids shadows caused by light blockage, emits light evenly, and is easy to install and remove.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A luminous speaker is provided, comprising a frame, a sound component, and a light-emitting component. The frame has a receiving cavity with one open end. The sound component is mounted on the frame and includes a cone. The cone covers the open end of the receiving cavity. The light-emitting component includes a lamp head and an annular light guide post. The light guide post is snapped onto the cavity wall of the receiving cavity and is located between the frame and the cone.

[0027] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 3 As shown, this utility model provides a light-emitting speaker, including a frame 1, a sound component 3, and a light-emitting component 2. The frame 1 provides overall support, and both the sound component 3 and the light-emitting component 2 are mounted on the frame 1. The sound component 3 is prior art; it is the sound-emitting part of the light-emitting speaker. Therefore, its specific structure and working principle will not be described in detail. The light-emitting component 2 emits light to enhance the lighting effect of the light-emitting speaker in its usage scenarios.

[0029] The frame 1 has an open-ended cavity 10, the opening of which corresponds to the sound output end of the luminous speaker. The cavity 10 is bowl-shaped, meaning it has a structure that is larger at one end and smaller at the other along its depth direction, with the bottom of the cavity being the smaller end and the opening being the larger end. A sound assembly 3 is mounted on the frame 1, including a cone 31. The cone 31 is bowl-shaped and covers the open end of the cavity 10, emitting sound through vibration. The light-emitting assembly 2 includes a lamp holder 22 and a light guide post 21. The light guide post 21 has a ring structure and is snapped onto the cavity wall of the cavity 10. The light guide post 21 is located between the frame 1 and the cone 31, forming a cavity, allowing the light emitted by the light guide post 21 to be directly projected onto the cone 31. The light guide post 21 serves as a light guide. When the light source shines on the end of the light guide post 21, the light propagates within the light guide post 21 and is evenly projected onto the speaker cone 31. The lamp holder 22 includes a PCB board and a light source electrically connected to the PCB board. The PCB board is used to control the switching, intensity adjustment, and color adjustment of the light source. The connecting end of the light guide post 21 passes through the speaker cone 1 and connects to the lamp holder 22.

[0030] Understandably, by installing the light guide column 21 inside the frame 1, uniform light can be emitted through the light guide column 21, and the light emitted by the light guide column 21 can be directly projected onto the cone 31. There are no other components obstructing the light guide column 21 and the cone 31, avoiding the problem of shadows. In addition, the light guide column 21 is directly snapped onto the cavity wall of the receiving cavity 10, which is convenient for installation and disassembly and easy for maintenance. The lamp head 22 is installed on the outside of the frame 1. When the light source malfunctions and needs to be replaced, or when the light source color needs to be changed according to the usage scenario, there is no need to disassemble the sound component 3 and the frame 1. The lamp head 22 can be replaced directly on the outside of the frame 1. Therefore, this luminous speaker has the characteristics of uniform light emission and convenient installation and removal.

[0031] Specifically, the cone 31 is made of a white, translucent material with a light transmittance of not less than 50%. The cone 31 can be made of materials such as Kevlar or fiberglass to provide strength and toughness.

[0032] Specifically, the basin stand 1 includes a main support 11 and a mounting frame 12. The main support 11 is the main body of the basin stand 1, and a receiving cavity 10 is formed within the main support 11. The mounting frame 12 is used to mount the light guide post 21. The mounting frame 12 is disposed on the cavity wall of the receiving cavity 10, and the light guide post 21 is snapped onto the mounting frame 12. Correspondingly, the mounting frame 12 has a circular structure and is disposed around the periphery of the receiving cavity 10. The hardness of the mounting frame 12 is less than that of the main support 11. The main support 11 provides overall support, therefore the main support 11 needs to have sufficient mechanical strength. The mounting frame 12 is used to mount the light guide post 21, and it can be made of a material with low hardness and elasticity to avoid damaging the light guide post 21. In this embodiment, the main support 11 and the mounting frame 12 are an integral structure, manufactured by injection molding. The mounting bracket 12 can be made of white TPU soft rubber (Thermoplastic polyurethanes), which serves to fix the light guide column 21 and improve the light reflectivity and light effect.

[0033] Specifically, the light guide post 21 is connected and fixed to the lamp head 22 by a plug-in connection, so as to facilitate the disassembly and assembly of the lamp head 22.

[0034] Specifically, refer to Figure 4 and Figure 5As shown, the mounting frame 12 includes a base plate, an inner side wall 122, and an outer side wall 123. The base plate is an annular plate that surrounds the inner side of the basin frame 1. Correspondingly, both the inner side wall 122 and the outer side wall 123 are annular plates that surround the inner side of the basin frame 1. Along the radial direction of the receiving cavity 10, the inner side wall 122 and the outer side wall 123 are spaced apart at both ends of the base plate, so that the inner side wall 122, the outer side wall 123, and the base plate form a mounting groove 121 for accommodating the light guide post 21. The light guide post 21 is installed in the mounting groove 121, which is beneficial for the mechanical protection of the light guide post 21. The opening of the mounting groove 121 faces the opening end of the receiving cavity 10. Part of the light emitted by the light guide post 21 can be directly projected onto the cone 31, and the other part of the light can be reflected by the groove wall of the mounting groove 121 and then projected onto the cone 31. The mounting bracket 12 also includes elastic clips 124, which are used to secure the light guide post 21. The elastic clips 124 are disposed on the inner sidewall 122, or on the outer sidewall 123, or on both the inner and outer sidewalls 122 and 123. In this embodiment, the elastic clips 124 are disposed on the outer sidewall 123, which has a notch, and the elastic clips 124 are installed within the notch. When the elastic clips 124 are subjected to external force, they can elastically deform, thereby securing the light guide post 21. To improve the stability of the light guide post 21, multiple elastic clips 124 are provided, spaced apart along the extension direction of the mounting groove 121 on the outer sidewall 123. Correspondingly, when the inner sidewall 122 is provided with elastic buckles 124, multiple elastic buckles 124 are spaced apart on the inner sidewall 122 along the extension direction of the mounting groove 121.

[0035] The mounting bracket 12 also includes limiting members 125, which are used to limit the installation position of the light guide post 21. Multiple limiting members 125 are spaced apart within the mounting groove 121 along its extension direction. Each limiting member 125 has a limiting groove 1251 into which the light guide post 21 is inserted. The dimensions of the limiting groove 1251 match the dimensions of the light guide post 21, ensuring a tight fit and preventing movement. By using the limiting members 125, a gap is created between the light guide post 21 and the groove wall of the mounting groove 121, reducing the obstruction of the light emission from the light guide post 21 by the groove wall and also reducing contact wear between the light guide post 21 and the mounting bracket 12.

[0036] Specifically, refer to Figure 2 and Figure 3As shown, the sound assembly 3 also includes a voice coil 32, a support 33, a magnetic circuit system 34, a dust cap 35, padding 36, and a wire 37. The voice coil 32 is mounted at the bottom of the frame 1, with one end extending into the receiving cavity 10, and the voice coil 32 is coaxial with the receiving cavity 10. The magnetic circuit system 34 includes a main magnet, a secondary magnet, and a magnetic guide plate, and is mounted inside the voice coil 32. The cone 31 has a bowl-shaped structure, with one side of the inner ring of the cone 31 fitted onto the voice coil 32, and one side of the outer ring connected to the open end of the frame 1. Padding 36 is placed at the open end of the frame 1, pressing down on one end of the outer ring of the cone 31 to ensure the airtightness of the cone 31. The dust cap 35 covers the end of the voice coil 32, serving a dustproof function. The support piece 33 is installed inside the receiving cavity 10. The support piece 33 has a circular structure. One side of the inner ring of the support piece 33 is fitted onto the voice coil 32, and the other side of the outer ring is connected and fixed to the inner wall of the frame 1. The support piece 33 is located between the voice coil 32 and the light guide post 21 to avoid the support piece 33 blocking the light from the light guide post 21.

[0037] Specifically, refer to Figure 6 As shown, wire 37 is used to connect voice coil 32 to an external power source. One end of wire 37 is connected to voice coil 32, and the other end is provided with a terminal block, which is mounted on the frame 1. To prevent wire 37 or the terminal block from affecting the light output of light guide post 21, the terminal block is installed below light guide post 21, that is, below mounting bracket 12. Alternatively, the terminal block is located on the side of light guide post 21 facing voice coil 32, that is, on the side of mounting bracket 12 facing voice coil 32. As a preferred embodiment, wire 37 is configured as a flat structure, and wire 37 is attached to the surface of support plate 33. This structure allows wire 37 to fit together with support plate 33, preventing wire 37 from moving into the cavity between receiving cavity 10 and voice cone 31, thereby preventing wire 37 from blocking the light output of light guide post 21 and causing shadows.

[0038] Specifically, the luminous speaker also includes an input module 4, which is used to transmit electrical energy and sound signals to the sound component 3. The input module 4 includes a wiring harness and / or terminals, and is disposed outside the frame 1 and electrically connected to the wire 37 via the wiring harness or terminals.

[0039] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
