Abstract: An adjustable head-mounted structure comprises overlapping and staggered first and second head strips, one end of each respectively arranged in a groove shaped bracket, the first head strip connected with the bracket. A sliding cavity extending along the first head strip is provided on an end thereof. Limiting slots are provided at lateral intervals of the sliding cavity. An elastic piece is connected with the second head strip having connecting and bending portions in an end notch of the second head strip. The bending, portion is inserted into the sliding cavity and clamped into a limiting slot. A through hole extending along the bracket is provided on a sidewall close to the limiting slot. A button in the bracket has a pressing portion to be inserted into the through hole and connected to a baffle plate, with a fixed connection structure between the baffle plate and the second head strip.

Abstract: A microphone boom structure includes a first and second end boom segments, and intermediate boom segments sequentially disposed between the first end boom segment and the second end boom segment. An end of the first end boom segment is hinged with an end of the adjacent intermediate boom segment, an end of the second end boom segment is hinged with an end of the adjacent intermediate boom segment, and the ends of two adjacent intermediate boom segments are hinged. An adjusting structure is provided between the first end boom segment and the adjacent intermediate boom segment, between the second end boom segment and the adjacent intermediate boom segment, and between the two adjacent intermediate boom segments. The adjusting structure includes an axial hole formed in a boom segment, an adjusting bar inserted into the axial hole, and an elastic compression member disposed between the axial hole and the adjusting bar.

Abstract: An automatic auto-sensing flood protection roller shutter with auto-locating reinforced column includes a door plate composed of a plurality of door panels, at least one reinforced column automatically movable by a motor to a reinforcing position behind the door plate when the door plate is lowered upon sensing a flood, and a bolt and bolt driving device for securing the at least one reinforced column in the reinforcing position.

Abstract: The invention provides an automatic auto-sensing flood protection roller shutter with auto-locating reinforced column, including a door plate, which is composed of a plurality of door panels; a casing, the interior thereof is provided with a motor, a hydraulic pump, an automatic controller, an uninterruptible power system, a storage device, a downward-pressing hydraulic cylinder and a driving device; two frames mounted on two sides of the door plate; a storage device; a downward-pressing hydraulic cylinder; a sideward-pressing hydraulic cylinder; a water level detector; a reinforced column, which is provided behind the door plate, and a vertical motor provided at the upper end thereof and another horizontal motor provided in the driving device, and the inner chamber at the lower end of the reinforced column being provided with a bolt and a vertical motor; and a driving device; thereby, the roller shutter according to the invention may achieve advantages of safe operation for waterproof and flood protection.

Abstract: The present invention provides an earphone and an implementation method of vibratile earphone. The earphone comprises: a low-frequency detection control circuit and a vibratile terminal connected to the low-frequency detection control circuit; the low-frequency detection control circuit is for sending a control signal to the vibratile terminal when detecting a signal of low-frequency below a specified frequency from earphone signals; the vibratile terminal produces vibration when receiving the control signal sent from the low-frequency detection control circuit. The solution of the invention can make the earphone produce vibration when the earphone signals contain low frequency signals and thus improve people's sense of shock when they are listening to voices or playing games with the earphone.
