The light-shielding layer is disposed under the cover plate and has a width less than about 4 mm. The light guide plate is disposed under the cover plate. The light guide plate has a reflective surface and a light-exiting surface opposite to each other, and a light-incident surface and three side surfaces connected between the reflective surface and the light-exiting surface. The light source is configured to emit light toward the light-incident surface. A surface roughness of the three side surfaces ranges from about 300 nm to about 400 nm, so that a change rate of brightness measured by any adjacent two of measuring points evenly distributed on the light-exiting surface is between about 8% and about 12%.

Abstract: The present disclosure discloses a smart speaker wake-up method, a smart speaker wake-up device, a smart speaker and a storage medium, relates to the technical field of speech recognition. The method of the present disclosure is applied to a wireless network including two or more smart speakers, and a specific implementation thereof is: receiving, speech information including a wake-up word; performing a recognition processing to the speech information to obtain identification information corresponding to the wake-up word; and waking up one smart speaker in the wireless network to enter listening state according to the identification information. The present disclosure may be applied to a scenario where multiple smart speakers coexist, so as to quickly select one smart speaker that is most likely to be wakened, avoiding a chaotic speech interaction caused by multiple smart speakers being wakened simultaneously, improving efficiency and quality of speech interaction and achieving better user experience.

Abstract: A pallet truck according to the present application includes a front frame, a rear frame, a lifting component, two fork bodies, a guide bar, a transmission device, and a load-bearing wheel assembly. The distance between the fork bodies can be adjusted by using the side-shifting driving component, thereby providing different fork distances and significantly improving the adaptability. During the adjusting process, the transmission device can switch the load-bearing wheel assembly from the longitudinal rolling state to the lateral rolling state, thereby avoiding wear of the wheels, which is beneficial to improving the overall life of the device and reducing the maintenance cost. In addition, the transmission device is pushed out as the rear frame is lifted, and thus the operation process is simple and reliable.
