An input device in an environment where pressure changes. The input device comprises a plate layer, a circuit layer, a keypad layer, a protection layer, and a sealed and liquid-tight space. The keypad layer is attached to the plate layer. The sealed and liquid-tight space is formed between the plate layer and the keypad layer. The circuit layer is disposed in the sealed and liquid-tight space. Furthermore, the plate layer has a first hole, and the circuit layer has a second hole corresponding to the first hole. The protection layer is attached to the plate layer and corresponds to the sealed and liquid-tight space. The air permeable rate of the protection layer is between 10% and 50% so that the inside pressure and the outside pressure of the input device can reach an equilibrium.

A terminal front cover assembly and a terminal, including a protective frame, a glass cover plate and waterproof glue, the protective frame includes a storage cavity, the storage cavity includes a first cavity wall, the first cavity wall includes a first part and a second part, and the glass cover part Accommodated in the storage cavity, the glass cover plate includes an upper surface and a side surface connected to the upper surface, the side surface includes a first connection surface and a second connection surface connected to the first connection surface, and the first connection surface is closely attached to the first part There is a first gap between the second connection surface and the second part, and the waterproof glue is arranged on the second connection surface to fill the first gap. The terminal front cover assembly and the terminal provided by the present invention divide the side of the glass cover plate into the first connection surface and the second connection surface, so that the first connection surface and the first part are closely attached, thereby preventing glue overflow during gluing ; There is a first gap between the second connection surface and the second part, and the waterproof glue is set on the second connection surface, so that there is enough space for glue to solve the problem of no extra space for glue.

The invention discloses a sensor. The sensor comprises a sensor probe, a connecting cable and an electric connector, the sensor probe comprises a sensor shell, a circuit board, a pressing cover, a pressing cap, a pressing ring and a sealing sleeve, the pressing cover, the pressing cap, the pressing ring and the sealing sleeve are each provided with a through hole for the connecting cable to penetrate through, and the outer side of the connecting cable is sequentially sleeved with the sealing sleeve, the pressing ring, the pressing cap and the pressing cover from inside to outside. The circuit board is installed in an inner cavity of the sensor shell. The outer surface of the first end of the pressing cover is connected with the inner wall of the top of the sensor shell in a matched mode. When one end of the connecting cable is connected with the circuit board of the inner cavity of the sensor shell, the inner wall of the second end of the pressing cover is matched with the outer wall of the pressing cap, the pressing ring can be axially pressed, the sealing sleeve can be axially pressed through the pressing ring, and therefore the connecting cable is clamped, and the waterproof and dustproof effects are achieved. Compared with the prior art, a sensor connecting cable can be clamped to achieve waterproof and dustproof effects, and the structure of the sensor is easy to miniaturize.

The invention relates to a novel LED fishing lamp. An existing fishing lamp is difficult to operate collectively and breaks easily, and broken residues threaten human health and pollute environment. The novel LED fishing lamp is formed by a drive part, a light source part, a heat-dissipating part and a fixing piece part. The drive part comprises a drive circuit board and a signal transmitting system. The light source part comprises an LED luminous body, a reflection cover, a lens, a lens support, a lens waterproof pad, a lens waterproof enhancing pad and an angle pad block. The heat-dissipating part comprises a heat-dissipating body, an end cover and an end cover waterproof pad. The fixing part comprises a fixing plate, a cover plate, an installing support, an installing base and a cover plate waterproof pad. A split type combination is adopted in the installing process, and the light source part is installed on the surface of the heat-dissipating body. An installing base is clamped into a slide groove of the side face of the fixing plate, and the installing base and the installing support are fixed on the fixing plate internally provided with the drive circuit board through screws. The cover plate and the end cover are fixed on the heat-dissipating body through the screws and the waterproof pads. The novel fishing lamp is simple and easy to assemble and disassemble, safe, waterproof, long in service life and beneficial for popularization, and saves energy.

The invention discloses an acoustical waterproof structure which comprises a vocal cavity main body, a vocal cavity and a rear cavity sealing sound source. The vocal cavity main body is connected with the rear cavity sealing sound source, and a vocal cavity is formed. The vocal cavity main body is provided with array micropores and a micropore sound guiding column. According to the technical scheme, the principle that the micropores are breathable and watertight is utilized, conventional acoustical cavity sound holes are modified into the dense array micropores, the array micropores effectively prevent water from entering an inner cavity while guaranteeing sound output, the waterproof and dustproof effects are achieved, and the acoustical waterproof structure can be widely applied to the design of various acoustic components.

The invention discloses a light and thin mobile terminal and a manufacturing method thereof. The light and thin mobile terminal comprises a terminal body, the terminal body comprises a housing; a framework arranged in the housing; a circuit board fixed in the framework, wherein circuit elements are arranged on the circuit board; and colloid filled in the framework. By means of the above manner, when a light and thin design is performed on the mobile terminal, the strength of the mobile terminal can be enhanced by the filled colloid, and in addition, after the colloid is filled, a waterproof and dustproof effect can be realized.
