DETAILED DESCRIPTION

[0036] With reference to the accompanying drawings, the technical solutions in the embodiments of the present disclosure will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts are within the scope of the present disclosure.

[0037] Figure 1 A schematic view of an electronic device provided in an embodiment of the present disclosure is shown in Figure 2 A partial cross-sectional view of an electronic device provided in an embodiment of the present disclosure is shown in some embodiments of the present disclosure, as shown in Figure 1 and 2 The electronic device includes a box body 1, a light assembly 2, and an elastic member 3. The box body 1 is provided with a mounting cavity 100, and the light assembly 2 is located in the mounting cavity 100. The light assembly 2 includes a lens module 200 and a light source 201. The light source 201 is fixedly connected to the box body 1. The lens module 200 is located on a side close to an opening of the mounting cavity 100. The lens module 200 is connected to an inner wall of the mounting cavity 100 through the elastic member 3. The elastic member 3 is configured to transmit the vibration of the electronic device to the lens module 200.

[0038] In the electronic device provided in the embodiment of the present disclosure, the lens module 200 of the light assembly 2 is connected to the box body 1 through the elastic member 3. During the playing of music by the electronic device, the vibration generated by the playing of music can be transmitted to the box body 1 and the elastic member 3. Since the elastic member 3 will elastically deform when vibrating, the vibration amplitude of the elastic member 3 will be much larger than that of the box body 1. The lens module 200 vibrates with a large amplitude under the action of the elastic member 3, so that the light effect of the light assembly 2 changes with the vibration of the elastic member 3, realizing the light effect following the rhythm of music. The controller is not needed to control the light assembly 2, and the use experience of the user is improved.

[0039] To make the technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings.

[0040] As shown in Figure 1 The electronic device includes a box body 1, a light assembly 2, and an elastic member 3. The box body 1 is provided with a mounting cavity 100 on a side thereof. The mounting cavity 100 has an opening. The light assembly 2 and the elastic member 3 are located in the mounting cavity 100. Referring to Figure 2The light assembly 2 comprises a lens module 200 and a light source 201. The light source 201 is fixedly connected with the box body 1. When the box body 1 vibrates, the structure that the light source 201 is fixedly connected with the box body 1 makes the light source 201 not transmit relative displacement with the box body 1. The lens module 200 is closer to the opening of the mounting cavity 100 relative to the light source 201. The light generated by the light source 201 can be emitted through the lens module 200. The lens module 200 is connected with the inner wall of the mounting cavity 100 through an elastic member 3. When the electronic device plays music, the vibration generated by the electronic device is transmitted to the box body 1 and then transmitted to the lens module 200 through the elastic member 3. Since the elastic member 3 will elastically deform when vibrating, the vibration amplitude of the lens module 200 is increased. When the lens module 200 vibrates, the distance between the lens module 200 and the light source 201 can be changed, so that the light passing through the lens module 200 changes with the vibration of the electronic device, that is, the light effect changes with the music, which is beneficial to improve the use experience.

[0041] In some embodiments of the present disclosure, the light source 201 can be directly fixedly connected with the box body 1, for example, the edge region of the light source 201 is bonded with the inner wall of the mounting cavity 100.

[0042] In some embodiments of the present disclosure, the light source 201 can be directly fixedly connected with the box body 1, for example, the edge region of the light source 201 is bonded with the inner wall of the mounting cavity 100. Figure 2 In some embodiments of the present disclosure, the electronic device further comprises a connecting piece 102. The connecting piece 102 is located in the mounting cavity 100. One side of the light source 201 away from the mounting cavity 100 is fixedly connected with the connecting piece 102. The connecting piece 102 is fixedly connected with the inner wall of the mounting cavity 100, or the connecting piece 102 is integrally formed with the box body 1. For example, the connecting piece 102 is columnar. The end of the connecting piece 102 is provided with a threaded hole. The light source 201 is connected with the threaded hole of the end of the connecting piece 102 through a bolt.

[0043] It should be noted that the fixed connection mentioned in the above embodiments can be a threaded connection, bonding, welding and the like. The present disclosure does not make specific limitations here.

[0044] In some embodiments of the present disclosure, as shown in Figure 2 The lens module 200 comprises a light guide member 202, a reflector 203 and a half mirror 204 which are sequentially stacked. The light guide member 202 is relatively close to the light source 201. The half mirror 204 is relatively far away from the light source 201. The reflector 203 is located between the light guide member 202 and the half mirror 204. The light generated by the light source 201 can be reflected between the reflector 203 and the half mirror 204 for multiple times, thereby forming a deep abyss mirror light effect. When the lens module 200 vibrates, the angle of the light generated by the light source 201 reflected by the reflector 203 and the half mirror 204 constantly changes, thereby forming a dynamic deep abyss mirror light effect.

[0045] In some embodiments, one end of the light guide 202 is opposite the light source 201, and the light guide 202 is configured to obliquely inject light generated by the light source 201 into the gap between the reflector 203 and the half mirror 204. The reflector 203 and the half mirror 204 are both flat plates, and the reflector 203 and the half mirror 204 are arranged in parallel. The light is obliquely injected into the gap between the reflector 203 and the half mirror 204 relative to the plane on which the reflector 203 or the half mirror 204 is located, so that the light is reflected and transmitted multiple times between the reflector 203 and the half mirror 204, thereby generating a gradual light effect.

[0046] In some embodiments of the present disclosure, as shown in Figure 2 and 3 The lens module 200 further includes a counterweight 205, which is located on the side of the light guide 202 close to the light source 201, and the counterweight 205 is connected to the side of the support plate 2021 close to the light source 201.

[0047] For example, the counterweight 205 can be a flat plate, and the side of the light guide 202 close to the light source 201 is provided with a limiting ring 2023, the counterweight 205 is located in the limiting ring 2023, and the counterweight 205 is fixedly connected to the light guide 202. The counterweight 205 can increase the weight of the light guide 202, thereby increasing the amplitude of the light guide 202 when vibrating, so that the change of the light effect is more obvious.

[0048] In some embodiments of the present disclosure, as shown in Figure 2 The elastic member 3 is provided with a recessed portion 301 recessed toward the side close to the light source 201. The recessed portion 301 can increase the surface area of the elastic member 3, thereby increasing the elastic deformation range of the elastic member 3, thereby increasing the amplitude of the lens module 200, so that the change of the light effect with the music is more obvious.

[0049] For example, the cross-sectional shape of the groove bottom of the recessed portion 301 is semicircular.

[0050] Figure 3 An exploded view of the electronic device provided in the embodiments of the present disclosure is provided. In some embodiments of the present disclosure, as shown in Figure 2 and 3 The elastic member 3 is annular, the inner ring of the elastic member 3 is connected to the lens module 200, and the outer ring of the elastic member 3 is connected to the inner side wall of the mounting cavity 100. The annular elastic member 3 can make the force on the lens module 200 more balanced, avoid the lens module 200 from being skewed when vibrating, and ensure the light effect of the light assembly 2.

[0051] In some embodiments of the present disclosure, as shown in Figure 3As shown, the electronic device further comprises a side cover 4 which is clamped with the inner wall of the mounting cavity 100. The side cover 4 is used to cover the edge area of the elastic member 3, and protect the devices inside the electronic device.

[0052] Optionally, as shown in FIG. 2, the mounting cavity 100 is provided with a support portion 101, and part of the elastic member 3 is clamped between the support portion 101 and the side cover 4. The outer ring portion of the elastic member 3 is clamped between the support portion 101 and the side cover 4, so as to fixedly connect the outer ring of the elastic member 3 with the cabinet 1. Figure 2 3 Optionally, as shown in FIG. 2, the mounting cavity 100 is provided with a support portion 101, and part of the elastic member 3 is clamped between the support portion 101 and the side cover 4. The outer ring portion of the elastic member 3 is clamped between the support portion 101 and the side cover 4, so as to fixedly connect the outer ring of the elastic member 3 with the cabinet 1.

[0053] Optionally, as shown in FIG. 2, the mounting cavity 100 is provided with a support portion 101, and part of the elastic member 3 is clamped between the support portion 101 and the side cover 4. The outer ring portion of the elastic member 3 is clamped between the support portion 101 and the side cover 4, so as to fixedly connect the outer ring of the elastic member 3 with the cabinet 1. Figure 3

[0054] Figure 4 A schematic diagram of an electronic device provided by an embodiment of the present disclosure is shown in FIG. 1. In some embodiments of the present disclosure, as shown in FIG. 1, the inner ring of the elastic member 3 is fixedly connected with the light guide member 202 and the half mirror 204. When the elastic member 3 vibrates, the light guide member 202 and the half mirror 204 simultaneously vibrate with the elastic member 3, the distance between the light guide member 202 and the light source 201 changes, and the angle of the light rays entering the gap between the reflector 203 and the half mirror 204 is adjusted, so that the light effect of the light assembly 2 changes with the vibration of the elastic member 3. Figure 4

[0055] A schematic diagram of another electronic device provided by an embodiment of the present disclosure is shown in FIG. 2. In some embodiments of the present disclosure, as shown in FIG. 2, the inner ring of the elastic member 3 is fixedly connected with the half mirror 204. When the elastic member 3 vibrates, only the half mirror 204 vibrates with the elastic member 3, and the light source 201, the light guide member 202 and the reflector 203 are in a static state relative to the cabinet 1. With the vibration of the elastic member 3, the distance between the half mirror 204 and the reflector 203 changes constantly, so as to constantly adjust the reflection times of the light rays entering the gap between the reflector 203 and the half mirror 204, thereby adjusting the light effect of the light assembly 2 based on the vibration of the elastic member 3. For example, when the gap between the reflector 203 and the half mirror 204 is large, the reflection times of the light rays in the gap between the reflector 203 and the half mirror 204 are small, so that the light intensity of the middle area of the half mirror 204 is weak. When the gap between the reflector 203 and the half mirror 204 is small, the reflection times of the light rays in the gap between the reflector 203 and the half mirror 204 are large, so that the light intensity of the middle area of the half mirror 204 is strong. Figure 5 Figure 5

[0056] Figure 6 ​​​​A schematic diagram of a light guide of an electronic device is provided in the embodiments of the present disclosure. In some embodiments of the present disclosure, as shown in Figure 7 The light guide 202 includes a support plate 2021 and a light guide ring 2022 connected to the edge region of the side of the support plate 2021 away from the light source 201, and the reflector 203 is connected to the side of the support plate 2021 away from the light source 201. The elastic member 3 is partially clamped between the light guide ring 2022 and the half mirror 204. When the elastic member 3 is connected to the half mirror 204 only, the side of the elastic member 3 away from the light source 201 is bonded to the half mirror 204. When the elastic member 3 is connected to the half mirror 204 and the reflector 203 respectively, the opposite sides of the elastic member 3 are bonded to the half mirror 204 and the reflector 203 respectively. The light guide ring 2022 is used to keep the half mirror 204 and the reflector 203 at a proper distance to achieve a better light effect, and the light guide ring 2022 is also used to make the light generated by the light source 201 obliquely enter the gap between the half mirror 204 and the reflector 203.

[0057] In some embodiments of the present disclosure, as shown in Figure 3 and 6 The light source 201 is a ring-shaped lamp panel, and the light source 201 is arranged opposite to the light guide ring 2022. Specifically, a plurality of LED (Light Emitting Diode) lamp beads can be arranged at equal intervals on the lamp panel, and each LED lamp bead can generate light of the same or different color and brightness.

[0058] In some embodiments of the present disclosure, the box 1 is cylindrical, and the two mounting cavities 100 are arranged at opposite ends of the box 1 respectively, and the lens module 200 of the two light assemblies 2 are connected to the inner walls of the mounting cavities 100 through the elastic members 3 respectively. The light assemblies 2 at the two ends of the box 1 can both achieve a light effect of dancing with music.

[0059] Optionally, the electronic device mentioned in the embodiments of the present disclosure can be a sound box. Alternatively, the electronic device can be other devices with a music playing function, such as a mobile phone, a computer, a radio, etc.

When the light enters the half mirror 204, part of the light is reflected by the half mirror 204, and the other part of the light is transmitted to the outside of the lens module 200 through the half mirror 204. The light reflected by the half mirror 204 enters the mirror 203 and is completely reflected by the mirror 203 to the half mirror 204. Part of the light is reflected by the half mirror 204, and the other part of the light is transmitted to the outside of the lens module 200 through the half mirror 204. The light is reflected and transmitted by the half mirror 204 multiple times. The light intensity of the area close to the light guide ring 2022 is large, and the light intensity of the area far from the light guide ring 2022 is small, and the light intensity gradually decreases away from the light guide ring 2022, thereby forming the abyss mirror light effect.
