[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the specific embodiments and corresponding drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0024] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection" and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] In order to solve the technical problems in the prior art, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0026] As Figures 1 to 4 shown, an embodiment of the present utility model discloses a light guide plate clamping mechanism, which includes a light guide plate body 1. The bottom of the light guide plate body 1 abuts against the edge of a light source fixing member. The light guide plate body 1 is made of a light-transmitting material. A plurality of connecting members 2 extend from one side edge of the light guide plate body 1. One end of the connecting member 2 is open to form a positioning notch 3, and a fastening member is inserted through the positioning notch 3.

[0027] The bottom of the light guide plate body 1 abuts against the edge of the light source fixing member, that is to say, the bottom of the light guide plate body 1 is attached to the edge of the light source fixing member. By forming a plurality of connecting members 2 on one side edge of the light guide plate body 1 and opening a positioning notch 3 on the connecting member 2, the installation and fixation of the light guide plate body 1 are realized by the cooperation of the positioning notch 3 and the fastening member. Instead of using a fully enclosed positioning notch 3, a semi-open positioning notch 3 is used to prevent the fastening member from being inserted into the positioning notch 3 and fixedly locked with the sound box housing. The light guide plate body 1 and the light source fixing member will not be pressed too tightly. When the sound box speaker emits sound and vibrates, it is not easy to generate tremors, which does not affect the sound effect of the sound box. At the same time, the light guide plate body 1 can also be fixedly installed on the sound box housing, and the light guide plate body 1 is made of a light-transmitting material, which does not affect the light irradiation of the light source fixing member.

[0028] In addition, the light source fixing member clamping mechanism covers the upper surface of the light source fixing member, playing a certain protective role for the light source fixing member. When other components are assembled above the light source fixing member, they are separated by the light source fixing member clamping mechanism, and other components do not directly contact the light source fixing member, so the light source fixing member will not be damaged.

[0029] A gap is formed between the light guide plate body 1 and the light source fixing member, that is, the light guide plate body 1 and the light source fixing member are not pressed too tightly. However, the light guide plate body 1 can be fixed on the audio under the cooperation of the positioning notch 3 and the fastener without loosening. When the audio speaker emits sound and generates slight vibration, it is not easy to produce noise or tremor. Preferably, the gap is 0.2 mm - 0.8 mm, and more preferably, the gap is 0.5 mm.

[0030] Furthermore, the light guide plate body 1 is made of light-transmitting PC material, generally a fully transparent PC material. To ensure the light-transmitting performance of the light guide plate body, the light emitted by the light source component on the audio passes through the light source fixing member and then passes through the light guide plate body 1 for illumination without affecting the lighting effect of the audio.

[0031] In addition, the color and material of the light guide plate body 1 can be specifically selected according to the color of the light emitted by the light source component, as long as it is ensured that the effect does not change after the light passes through the light guide plate body 1.

[0032] The light guide plate body 1 and the connecting member 2 are of an injection-molded integral structure.

[0033] In practical applications, a light source such as a light strip or lamp beads is fixed on the light source fixing member. Or rather, the light source fixing member is at the non-light-emitting edge of the light source, and the light guide plate body will not be directly pressed tightly against the lamp beads or light strip, that is, the light guide plate body will not press on the lamp beads or light strip.

[0034] The light source fixing member is installed in the groove of the audio housing. Usually, when designing, the other side edge of the light guide plate body 1 is abutted against the audio speaker, and the audio speaker and the connecting member 2 limit and fix the light source fixing member. Specifically, if the installation position of the light source fixing member is lower than the audio speaker, only a connecting member 2 needs to be provided on one side of the light guide plate body 1. A fastener is installed in the positioning notch 3 on the connecting member 2. By abutting the other side of the light guide plate body 1 against the audio speaker and the bottom of the light guide plate body 1 against the edge of the light source fixing member, the light source fixing member is limited and fixed between the audio speaker and the connecting member 2.

[0035] Of course, a connecting member 2 can also be provided on the other side of the light guide plate body 1. The connecting member 2 is also provided with a positioning notch 3, and a fastener is passed through the positioning notch 3. Through the connecting members 2 and fasteners on both sides of the light guide plate body 1, the bottom of the light guide plate body 1 is firmly abutted against the edge of the light source fixing member, and the specific design of the connecting member 2 can be adjusted according to the requirements of the product.

[0036] In a specific example, the positioning notch 3 is provided with a positioning hole and a fixing hole. The positioning hole is communicated with the fixing hole, and the fixing hole extends to the outer peripheral edge of the connecting member 2. The fastener is passed through the positioning hole, and the fixing hole prevents the positioning hole of the connecting member 2 from cracking during the locking process of the fastener.

[0037] Generally, the positioning notch 3 is designed in a U-shaped configuration.

[0038] In some embodiments, a positioning portion 4 is provided on a side of the connecting member 2 facing the light source fixing member, and a limiting portion 5 is protruded on the positioning portion 4 and is disposed around the outer periphery of the positioning notch 3.

[0039] Generally, an installation opening matching the positioning notch 3 is provided on the sound device, and the installation opening can be protruded to form an installation post. A fastener is passed through between the positioning notch 3 and the installation opening to fixedly install the light guide plate body 1 on the sound device. A limiting portion 5 is additionally provided on a side of the connecting member 2 close to the light source fixing member, and the limiting portion 5 is protruded on the surface of the positioning portion 4 and is disposed around the outer periphery of the positioning notch 3, which facilitates the positioning of the position of the fixing opening and the positioning notch 3 to achieve quick installation. During assembly, the limiting portion 5 surrounds the outer periphery of the installation post to limit the moving positions of the connecting member 2 and the light guide plate body 1, and also strengthens the connection strength and reliability between the positioning notch 3 and the installation opening.

[0040] In addition, a positioning groove matching the limiting portion 5 can also be provided on the outer periphery of the installation opening. During installation, the limiting portion 5 on the connecting member 2 is engaged with the positioning groove to achieve quick positioning installation, and also plays a role in limiting the movement of the connecting member 2 and the light guide plate body 1.

[0041] In a specific example, at least two limiting portions 5 are protruded on the positioning portion 4, and the at least two limiting portions 5 enclose to form a clamping space.

[0042] In some embodiments, one limiting portion 5 is protruded on the positioning portion 4, and a limiting space is formed between the limiting portions 5 on adjacent connecting members 2.

[0043] Only one limiting portion 5 needs to be provided on the positioning portion 4, and the quick positioning and connection strength of the connecting member 2 can also be ensured. Specifically, only one limiting portion 5 is provided on adjacent connecting members 2, the positioning notch 3 on each connecting member 2 is connected to the installation opening, and along the preset direction of the light guide plate body 1, the adjacent limiting portions 5 are oppositely arranged. The limiting portion 5 abuts against the installation post, or the limiting portion 5 is embedded in the positioning groove, which can ensure that the connecting member 2 does not move easily.

[0044] In some embodiments, an arc portion is provided on a side of the limiting portion 5 close to the positioning notch 3. The arc portion can abut against the outer periphery of the installation post, and the installation positions of multiple connecting members 2 are accurately positioned, and the connection between the limiting portion 5 and the installation post is reliable.

[0045] The limiting portion 5, the connecting member 2, and the light guide plate body 1 are integrally injection-molded by an injection molding method.

[0046] In some embodiments, a reinforcing rib structure 6 is provided on the side of the light guide plate body 1 away from the light source fixing member. The strength of the light guide plate body 1 is enhanced by the reinforcing rib structure 6.

[0047] In some embodiments, a silicone positioning member is further provided. The silicone positioning member is provided on the edge of the light source fixing member, and the bottom of the light guide plate body 1 abuts against the silicone positioning member. The light guide plate body 1 is pressed tightly against the light source fixing member or the silicone positioning member on the edge of the light source fixing member to avoid rattling caused by insufficient pressing, and the positioning notch also prevents the light guide plate body from being pressed too tightly.

[0048] The silicone positioning member can be selected in an L shape to limit and fix the light source fixing member in the light source fixing member installation groove designed on the sound box housing. The light guide plate body 1 made of a transparent material is installed above and cooperates with the silicone positioning member, so that it does not look obtrusive in appearance.

[0049] In practical applications, the light guide plate body 1 is designed as an annular structure. A connecting member is formed at the outer peripheral edge of the light guide plate body 1, and the inner periphery of the light guide plate body abuts against the sound box speaker. The width of the light guide plate body 1 is specifically set according to the positions among the light source fixing member, the sound box speaker, and the corresponding mounting openings of the connecting member.
