[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a loudspeaker, including a basin frame 1, a diaphragm 2 and a light-emitting component 3. The diaphragm 2 includes a vibration portion 21 and a connecting ring edge 22 connected to the outer edge of the vibration portion 21. The connecting ring edge 22 is fixed to the basin frame 1 to enclose an installation space 11 between the inner surface of the diaphragm 2 and the inner wall surface of the basin frame 1. The light-emitting component 3 is arranged in the installation space 11.

[0029] The diaphragm 2 is a light-transmitting member, the light transmittance of the connecting ring edge 22 is lower than the light transmittance of the vibration part 21, and the light-emitting member 3 is located below the connecting ring edge 22 in the height direction of the installation space 11. The height direction of the installation space 11 refers to the direction perpendicular to the plane where the connecting ring edge 22 is located.

[0030] Specifically, the light-emitting element 3 is connected to an external power source and a controller through a flexible circuit board. When the speaker makes a sound, the controller controls the light-emitting element 3 to emit light through a specific signal. Since the diaphragm 2 is a light-transmitting component, the light generated by the light-emitting element 3 can be transmitted outward through the light-transmitting diaphragm 2, presenting a corresponding lighting effect, so as to realize the combination of sound and light and enhance the use atmosphere.

[0031] The light transmitted through the translucent diaphragm 2 becomes soft, which significantly improves the experience of the people in the car. Moreover, in the height direction of the installation space 11, the light-emitting component 3 is located below the connecting ring edge 22. Since the transmittance of the connecting ring edge 22 is lower than the transmittance of the vibration part 21, the connecting ring edge 22 has a better light shielding effect, thereby preventing the light emitted from the diaphragm 2 from being too dazzling when the user looks directly at the light-emitting component 3 from the outside of the diaphragm 2, thereby reducing safety hazards.

[0032] At the same time, the speaker in the prior art also has the following defects: the light-emitting element 3 is arranged between the mesh cover and the speaker, and the air in the space between the speaker and the mesh cover is in natural convection, so that the air and the light-emitting element 3 are in a passive heat transfer state, resulting in slow heat dissipation of the light-emitting element 3. In addition, part of the light generated by the light-emitting element 3 is blocked by the mesh cover, and the efficiency of light transmission into the cockpit is low. The speaker of the utility model can also solve the above defects, and the specific principle is as follows: when the speaker makes a sound, the vibration part 21 vibrates, and after the vibration of the vibration part 21, it can drive the air in the installation space 11 to move with it, and the flowing air contacts the light-emitting element 3 and passes over the surface of the light-emitting element 3 to take away the heat generated by the light-emitting element 3. That is, the speaker uses the vibration of the vibration part 21 as a power to drive the air flow in the installation space 11, realize forced convection of the air in the installation space 11, and improve the heat dissipation speed of the light-emitting element 3.

[0033] The light-transmitting diaphragm 2 can also prevent the light emitted by the light-emitting element 3 from being blocked, so that the light can be efficiently transmitted to the outside of the diaphragm 2 .

[0034] Moreover, the diaphragm 2 can be combined with different color blocks so that the diaphragm 2 has light transmittance of different colors to enrich the lighting effect.

[0035] In the speaker of the utility model, the light-emitting component 3 is arranged in the installation space 11 surrounded by the inner surface of the diaphragm 2 and the inner wall surface of the basin frame 1. The light-emitting component 3 is located on the inner side of the diaphragm 2, and the light emitted by the light-emitting component 3 can be dispersed outward through the light-transmitting diaphragm 2. The light transmitted through the light-transmitting diaphragm 2 will become soft, which significantly improves the experience of the people in the car. Moreover, in the height direction of the installation space 11, the light-emitting component 3 is located below the connecting ring edge 22. Since the light transmittance of the connecting ring edge 22 is lower than the light transmittance of the vibration part 21, the connecting ring edge 22 has a better light shielding effect, so as to avoid the light emitted from the diaphragm 2 being too dazzling when the user looks directly at the light-emitting component 3 from the outside of the diaphragm 2, thereby reducing safety hazards.

[0036] In one embodiment, a support platform 12 is provided on the inner wall of the basin frame 1, and the support platform 12 has a support surface facing the connecting ring edge 22.

[0041] In one embodiment, if Figure 4 As shown, the basin frame 1 includes a plurality of support ribs arranged at intervals around the vibration part 21, and each support rib is provided with a support platform 12.

[0043] In one embodiment, the communication port extends along the height direction of the installation space 11 , so that air at various positions along the height direction of the installation space 11 can flow through the communication port, which is beneficial to balancing the flow speed of air at various locations in the installation space 11 .
