Abstract: A miter saw includes a worktable and a cutting unit. The cutting unit includes a movable arm pivotably connected with the worktable, a saw blade, a triggering switch and a tilt power-off module. The movable arm defines a reference plane which intersects a working surface of the worktable at an included angle. The tilt power-off module is disposed to detect the included angle and shift the triggering switch between a power-on state and a power-off state. The triggering switch is shifted to the power-off state when the tilt power-off module detects that the included angle is less than a predetermined breaking angle so as to prevent rotation of the saw blade in a folded position for safety purposes.

Abstract: A treadmill with a safety warning function includes a miming unit, a driving unit, a detection unit and a control unit. The running unit includes a driving roller and a running belt provided for a runner to stand thereon. The detection unit includes a camera arranged at a predefined height range on top of the running belt for photographing images. The control unit determines a height of the runner based on the images photographed. The safety monitoring method for the treadmill includes obtaining an image above the running belt and determining whether the height of the runner is greater than the predefined height. By determining whether the height of the runner is greater than the predefined height, it is able to determine whether the driving roller can be driven by the driving unit to rotate, thereby preventing the hazard of accidental activation by a child of insufficient height.

Abstract: An optical film to visually reduce frame size of individual display units within a single large display includes four film portions connected to each other to form a rectangular frame of each individual display unit. Each film portion has strip-shaped micro-structures of triangular cross-section, and includes a bottom surface, a first side surface, and a second side surface. The bottom surfaces of the micro-structures are connected to each other. The first side surfaces and the second side surfaces are obliquely connected, the second side surface of one micro-structure being at the outermost side of each film portion. Angle ?1 between the first side and bottom surface of each micro-structure is less than angle ?2 between the first side surface and the second side surface and the sum of first and second angles ?1 and ?2 is less than 90°.

Abstract: A massage device includes a housing, and a first driving assembly, a second driving assembly, and a massage assembly received in the housing. The first driving assembly includes a first driving motor. The second driving assembly includes a second driving motor mounted to the housing, and a shaft handle mounted to the second driving motor and abutting against a bottom surface of the second end. The massage assembly includes a fixing frame and a massager received in the fixing frame. The fixing frame includes a first end pivotally connected to the housing and an opposite second end. The first driving motor can drive the massager reciprocally. The second driving motor can drive ends of the shaft handle to move circumferentially, thereby causing the second end to move back and forth perpendicular to the extending direction.

Abstract: An audio playing method is applied to at least one wireless speaker, at least one mobile terminal, and a cloud server. The method includes sending a wireless signal within a coverage area of the wireless speaker, the wireless signal being detected by the speaker when the speaker is in proximity to the mobile terminal. The first identification information of the wireless speaker and second identification information of the mobile terminal are obtained, and control signals indicating the first and the second identification information is transmitted to the cloud server. Audio files corresponding to the second identification information are decoded into an audio stream and the audio stream is transmitted to the one or more wireless speakers which correspond to the first identification information included in the control signal.

Abstract: A speaker includes a hollow casing, a vibration plate, a vibrator, a wireless communication unit, and a processor. The casing defines a receiving space. The vibration plate is secured to the casing, and includes a first portion received in the receiving space and a second portion protruding out of the casing. The vibrator is received in the receiving space and attached to the first portion. The processor is configured to control the vibrator to vibrate when the speaker receives a wireless signal via the wireless communication unit, thereby allowing the vibration plate to vibrate and output sound.
