Description

Technical Field

[0001] The utility model relates to the technical field of indoor audio-visual systems, in particular to a bed with a multi-channel surround sound system. Background Art

[0002] With the continuous development of science and technology, various convenient audio-visual entertainment devices have entered thousands of households. As a new generation of video display devices, projectors with the advantages of small body, convenient projection, and large screen size are actively replacing the position of traditional TVs in rooms, especially bedrooms. For current home projector products, the research and development focus of manufacturers is concentrated on the visual experience level, and they are constantly iterating in the fields of light source, chip, display technology, etc. However, in terms of auditory experience, due to the constraints of the product's own size and placement, it is impossible to provide a good experience through the projector device itself. Although some home projector products on the market are integrated with stereo speakers, the following two reasons cause their sound effects to fail to achieve ideal effects. First, the stereo speakers on the projector body are closely spaced, close to a single point sound source, and the playback effect is not much different from mono, and it is even more impossible to achieve the multi-channel surround sound effect commonly used in movies and games today; second, except for ultra-short-throw projectors, whether it is front projection or side projection, the position of the projector when working needs to be far away from the projected picture, resulting in inconsistent sound source direction and picture position, and unnatural audio-visual experience. To achieve the ideal auditory effect, other sound playback devices are needed.

[0003] The current mainstream home surround sound playback system consists of an independent amplifier connected to several passive speakers placed in various places in the room through audio cables. On the one hand, this method has scattered equipment layout and takes up more space. On the other hand, there are many cables and they are difficult to hide, which affects the aesthetics of the interior. The above system is often used in living rooms with relatively flexible space layout, but is not suitable for compact bedrooms. In addition, there are long strips of audio playback devices such as echo walls on the market. Through acoustic algorithm simulation, the device located directly in front creates a multi-channel surround playback effect. Such products can bring certain improvements to the audio-visual entertainment experience, but there is still a big gap compared to the effect presented by the real physical multi-channel surround playback system.

[0004] In summary, in response to the existing problems, the present application combines a surround sound system with a bed frame to provide a new way to achieve physical surround sound playback for people who need to perform audio and video entertainment in the bedroom. Utility Model Content
