[0014] This utility model proposes a loudspeaker structure 100.

[0015] Please see Figures 1 to 2In one embodiment of the present invention, the loudspeaker structure 100 includes a bracket 6 and a magnetic circuit system 7. The magnetic circuit system 7 is disposed on the bracket 6. The loudspeaker structure 100 also includes a vibration system 1 and a light strip 2. The vibration system 1 includes a diaphragm 11 and a spring 12. The spring 12 is disposed on the bracket 6 and located on one side of the magnetic circuit system 7. The spring 12 is connected to the bracket 6. The diaphragm 11 is made of a transparent material. The light strip 2 is disposed on the spring 12 and is configured to emit light through the diaphragm 11 to the outside.

[0016] In this embodiment, the speaker structure 100 can be applied to electronic devices such as smart speakers and car audio systems, and is not limited here. The bracket 6 is used to fix and support other components. The material of the bracket 6 may include, but is not limited to, aluminum alloy, stainless steel, etc. The magnetic circuit system 7 is used to provide a strong magnetic field, enabling the voice coil 4 to efficiently convert electrical signals into mechanical vibrations in the magnetic field, thereby driving the diaphragm 11 to produce sound. The vibration system 1 is used to convert electrical signals into mechanical vibrations, thereby generating sound. The diaphragm 11 is in direct contact with the air and generates sound waves. Its material is a transparent material, which may be polyester film or polypropylene, etc., and is not limited here. The spider 12 is located on one side of the magnetic circuit system 7 and connected to the bracket 6. It can be understood that the connection between the spider 12 and the bracket 6 is adhesive. The material of the spider 12 includes, but is not limited to, rubber, polyurethane foam, etc. The light strip 2 emits light through the transparent diaphragm 11, providing a unique visual effect for the speaker and increasing the aesthetics and technological feel of the speaker structure 100. The light strip 2 can be manufactured using a flexible circuit board or a rigid circuit board, and can be installed on the spring 12 by means of welding, bonding, etc., with bonding being the preferred method. Specifically, first apply a ring of glue to attach the spring 12 to the bracket 6, and then apply another ring of glue to the edge of the spring 12 to bond the light strip 2 to the annular part of the spring 12.

[0017] The speaker structure 100 provided by this utility model solves the problem that traditional speakers cannot achieve aesthetic lighting effects while emitting sound by using a transparent diaphragm 11 and a light strip 2 disposed on a spider 12. Specifically, the diaphragm 11 is made of transparent material, allowing light to propagate through it; the light strip 2 is disposed on the spider 12, which is located above the magnetic circuit system 7 and connected to the diaphragm 11, providing a stable mounting position for the light strip 2. The light emitted by the light strip 2 passes through the transparent diaphragm 11 to the outside, forming a unique visual effect. The transparent diaphragm 11 ensures sound propagation performance without affecting light transmission; the light strip 2 allows the speaker to display lighting effects simultaneously while emitting sound, increasing the product's aesthetics and technological feel, and enhancing the user experience.

[0018] In one embodiment of the present invention, the spring wave 12 includes a wave portion and an annular portion, the annular portion is disposed around the outside of the wave portion and is disposed on the bracket 6; the light strip 2 is arranged in an annular shape and is arranged along the circumference of the annular portion.

[0019] In this embodiment, combined with Figure 2 and Figure 3 To make full use of space, the wave section and the annular section utilize space efficiently, making the overall structure of the speaker more compact. The wave section connects to the voice coil 4. The wave section has a corrugated structure with good elasticity, transmitting the vibration of the voice coil 4 to the entire vibration system 1, ensuring that the movement of the voice coil 4 is effectively converted into the vibration of the diaphragm 11, thereby generating sound waves. The annular section connects to the bracket 6 and provides stable support for the spider 12. The annular section ensures the correct position of the wave section and the voice coil 4 on the bracket 6, preventing displacement or shaking during vibration and ensuring the stability and consistency of the vibration system 1. The circumferential direction of the annular section provides an installation position for the light strip 2, allowing the light strip 2 to be evenly distributed on the outside of the spider 12, ensuring that light can evenly pass through the transparent diaphragm 11, forming an aesthetically pleasing visual effect. It is understood that the spider 12 can be manufactured using processes such as injection molding or die molding. The outer edge of the annular section is aligned with the outer edge of the light strip 2.

[0020] In one embodiment of the present invention, the light strip 2 includes a plurality of light beads 21 and a light ring 22. The light ring 22 is disposed on one side of the annular portion, and the outer diameter of the light ring 22 is consistent with the outer diameter of the annular portion. The plurality of light beads 21 are spaced apart along the extending direction of the light ring 22.

[0021] In this embodiment, combined with Figure 3 The LED beads 21 are used to emit light, providing visual effects for the speaker. Multiple LED beads 21 are spaced apart along the extension direction of the LED ring 22, ensuring uniform light distribution and avoiding uneven brightness, resulting in a more uniform and aesthetically pleasing visual effect. The LED ring 22 provides support and a fixing structure for the LED beads 21, ensuring their stability and reliability during operation, preventing loosening or damage due to vibration or external forces. The outer diameter of the LED ring 22 is consistent with the outer diameter of the annular portion, ensuring a tight fit of the LED ring 22 on the annular portion without loosening or gaps, guaranteeing the compactness and aesthetics of the overall structure. The spaced LED beads 21 along the extension direction of the LED ring 22 ensure uniform light distribution, forming a uniform annular light source, avoiding uneven brightness, and resulting in a more aesthetically pleasing and comfortable visual effect.

[0022] In one embodiment of the present invention, the diaphragm 11 includes a body 111 and an adhesive edge 112, the body 111 and the adhesive edge 112 are connected, and both the body 111 and the adhesive edge 112 are made of transparent materials.

[0023] In this embodiment, combined with Figure 2The body 111 is the main part of the diaphragm 11, directly participating in vibration and converting the mechanical vibration of the voice coil 4 into sound waves. The adhesive edge 112 connects the body 111 and the support 6, providing stable support and fixation for the diaphragm 11, ensuring that the diaphragm 11 does not loosen or shift during vibration; simultaneously, the adhesive edge 112 also provides good sealing to prevent air leakage. It is understood that the material of the adhesive edge 112 is transparent TPU (thermoplastic polyurethane elastomer rubber), and the material of the body 111 is polypropylene, polycarbonate, etc., without limitation here.

[0024] In one embodiment of the present invention, the end of the body 111 away from the glue edge 112 gradually expands to the end of the body 111 near the glue edge 112.

[0025] In this embodiment, combined with Figure 2 It should be noted that this gradually expanding design allows for a more uniform stress distribution on the diaphragm 11 during vibration, reducing distortion and thus improving the clarity and consistency of the sound quality. Simultaneously, the use of a transparent material for the body 111 allows light to diffuse more evenly through the diaphragm 11, enhancing the visual effect.

[0026] In one embodiment of the present invention, the speaker structure 100 further includes a terminal block 5 and a voice coil 4. The terminal block 5 is disposed on one side of the bracket 6. A first cable is connected between the terminal block 5 and the light strip 2, and a second cable is connected between the terminal block 5 and the voice coil 4.

[0027] In this embodiment, combined with Figure 2 To centrally manage power and signals, a junction box 5 is located on one side of the bracket 6. The connection between the junction box 5 and the bracket 6 can be adhesive, soldering, snap-fit, etc., and is not limited here. The junction box 5 is connected to the light strip 2 via a first cable and to the voice coil 4 via a second cable, thereby enabling power supply and signal control for the light strip 2 and the voice coil 4. This setup, through the junction box 5, centrally manages power and signals, ensuring that the voice coil 4 receives a high-quality audio signal, improving the clarity and consistency of the sound quality. The junction box 5 controls the light-emitting mode of the light strip 2, synchronizing it with the music rhythm to enhance the visual effect. It is understood that the material of the junction box 5 can be copper plate, insulating plastic, etc., and is not limited here. Specifically, the first cable connected to the light strip 2 is connected to the junction box 5 and soldered together with the second cable connected to the voice coil 4 to achieve conductivity together with the voice coil 4. The wires of the junction box 5 are then connected to an external circuit board, through which the light color and dynamic effects can be changed according to the program signal.

[0028] In one embodiment of the present invention, the loudspeaker structure 100 includes a dust cap 3, which is located at the center of the diaphragm 11 and connected to the diaphragm 11.

[0029] In this embodiment, combined with Figure 2 The dust cap 3 is used to prevent dust from entering and can also reduce vibration interference at the center of the diaphragm 11, optimize the vibration mode of the diaphragm 11, and improve the clarity and consistency of the sound quality. It is understood that the material of the dust cap 3 includes, but is not limited to, polycarbonate, polypropylene, etc., and is not limited here. The connection between the dust cap 3 and the diaphragm 11 includes, but is not limited to, adhesive bonding, hot melt bonding, etc., with adhesive bonding being preferred here.

[0030] In one embodiment of this utility model, the dust cap 3 is made of a transparent material.

[0031] In this embodiment, in order to further improve the light transmittance of the diaphragm 11, the transparent dust cap 3 is coordinated with the transparent diaphragm 11 to form a unified visual effect, which enhances the aesthetics and technological feel of the speaker.

[0032] In one embodiment of the present invention, the vibration system 1 further includes a voice coil 4, which is located at the center of the diaphragm 11. The spider 12 is connected to the voice coil 4, and the voice coil 4 is connected to the diaphragm 11.

[0033] In this embodiment, combined with Figure 2 The voice coil 4 is used for electromagnetic drive. When current passes through the voice coil 4, it experiences electromagnetic force in the magnetic field, causing it to reciprocate. The voice coil 4 connects to the diaphragm 11, converting the electromagnetic force into mechanical vibration, which drives the diaphragm 11 to produce sound. The spider 12 connects the voice coil 4 and the support 6, providing elastic support for the voice coil 4 and the diaphragm 11, ensuring the stability and consistency of the vibration. It should be noted that the connection between the voice coil 4 and the diaphragm 11 can be achieved through adhesive bonding, mechanical fixation, etc., and the connection between the spider 12 and the voice coil 4 can also be achieved through adhesive bonding, mechanical fixation, etc., without limitation here.
