Disclosed is a self-powered formaldehyde sensing device, comprising: a triboelectric material electrode layer including a first substrate and a first electrode layer formed on the first substrate; a triboelectric material dielectric layer including a second substrate, a second electrode layer formed on the second substrate, a dielectric reacting layer formed on the second electrode layer, and a reaction modification layer formed on the dielectric reacting layer to surface-modify the dielectric reacting layer, the reaction modification layer being a phosphomolybdic acid complex (cPMA) layer, the phosphomolybdic acid complex of the phosphomolybdic acid complex layer being obtained by dissolving 4,4'-bipyridine (BPY) in isopropanol (IPA) and then mixing with phosphomolybdic acid (PMA) solution; an elastic spacer; and an external circuit.

Self-powered formaldehyde sensing device

An electronic device includes a first body, a second body, two hinges, and at least one electronic assembly. The two hinges are connected between the first body and the second body, and the first body and the second body are adapted to rotate relatively through the two hinges. The electronic assembly is connected to the second body and is located between the two hinges.

An electronic device including a base, a display and a functional assembly is provided. The display is movably connected to the base and adapted to act between a lower position and an upper position relative to the base. The functional assembly is movably connected to the base and adapted to act between a first state and a second state relative to the base. When the display acts to the upper position from the lower position, the functional assembly acts to the second state from the first state, and when the functional assembly acts to the first state from the second state, the display acts to the lower position from the upper position.

A rotation resetting device and an electronic apparatus are provided. The rotation resetting device includes a functional unit, a limiting block and an elastic unit. The functional unit includes a functional element and a supporting element connected to the functional element, wherein the supporting element includes a limiting gasket. The limiting block has an accommodating space with an opening and a taper chute extending downward from the opening. The elastic unit is located in the accommodating space and connected between the limiting block and the functional unit. The functional unit is movably disposed in the accommodating space and is capable of moving between an use position and a storage position relative to the opening. When the functional unit moves from the use position to the storage position, the limiting gasket abuts the taper chute, and rotates and slides downward along the taper chute while compressing the elastic unit.

Rotation resetting device and electronic apparatus

A method and a portable electronic apparatus for adaptively adjusting a playback effect of speakers are provided. The portable electronic apparatus includes a speaker enclosure volume adjusting device and a processor coupled to the speakers and the speaker enclosure volume adjusting device. In the method, the processor detects a usage demand for the portable electronic apparatus and accordingly determines an audio mode. Based on the determined audio mode, the processor selects and activates multiple speakers, and adjusts an enclosure volume of at least one of the activated speakers, so as to change an audio frequency range of the at least one speaker and an overall audio frequency range covered by the activated speakers. Finally, the processor plays an audio through the activated speakers.
