The present disclosure relates to the technical field of audio devices, and in particular, to a light-emitting device and an audio device.
With the progress of society, people yearn for a more colorful life. Vocal music can cultivate people's sentiments, and can also add a touch of fun to a busy life and make people relax. An audio device is a device that can restore and play audio signals, which can meet people's needs for sound amplification.
Portable audio devices can be suitable for outdoor entertainment, but also for computer amplification. Portable audio devices are more popular because of small size and long playback time, loud external speakers, and no damage to the eardrum.
However, with the improvement of living standards, people not only pay attention to the audio function, but also have higher and higher requirements for its appearance. Manufacturers hope to improve the appearance of the audio device under the premise of taking into account the sound performance, so as to enhance the market competitiveness of their products. Therefore, how to take into account the sound performance and aesthetics has become an urgent problem to be solved.

In an embodiment, as shown in
The upper cover 11 is made of aluminum material, so as to have characteristics such as light weight and high strength. This makes it easy for the press part 13 located on the upper cover 11 to have a better press effect. Along the axial direction of the main body 1, the press region 131 is located on the upper surface of the upper cover 11, providing a force application point for the user to meet the press requirements.
In order to further improve the aesthetics and feel of the upper cover 11, the main body 1 further includes a textured structure (not shown in the figures). The textured structure is formed on a surface of the upper cover 11 away from the lower cover 12, that is, on the surface where the press region 131 is located, to increase the visual effect. The textured structure may include, for example, the texture of an optical disc, and have colorful patterns. With different viewing angles, positions of the colorful patterns also move regularly, and the colorful patterns always maintain a symmetrical pattern, so that the upper cover 11 presents different aesthetics.
The lower cover 12 is made of high-transparency plastic and is formed by injection molding. During the injection molding process, light diffusing powder may be added to enhance the spreading and diffusivity of the light sources 22, and block the point light source, making it to become an area light source. This ensures that light emitted by the light sources 22 as a whole is softer and more beautiful, and achieves the comfort effect of light transmission and opacity. Further, sufficient lighting is also ensured without being dazzling.
