The utility model provides a kind of micro loudspeaker module, belong to loudspeaker module technical field. Including shell, further include: buffer component, buffer component is placed in the inside of shell, buffer component includes the protective shell being set in the inside of shell, the inside of protective shell is provided with circuit board, the end of the inside of shell close to circuit board is provided with spring piece, spring piece is annular array distribution on shell;Fixed component, fixed component is placed in the inside of shell and is used to fix spring piece, fixed component includes being connected in the inside of shell close to support, the side of support close to spring piece is provided with clamping groove, spring piece is clamped with support by clamping groove;By setting buffer component, protective shell outside and annular arrangement spring piece on shell contact, when protective shell is impacted by force and generates displacement in shell and extrudes spring piece, spring piece is buffered by the deformation of itself, to protect circuit board, avoid its damage due to excessive impact force, help to improve the stability of micro loudspeaker module when using.

The utility model discloses a flexible modular engine bracket, which belongs to the technical field of automobiles, and is characterized by comprising a bracket body, a cavity is formed in the inner side of the top of the bracket body, a steel net rack is fixedly connected to the top side in the cavity, and the bracket body, the cavity, the steel net rack, a sliding chute, a positioning assembly and a buffer assembly are arranged, so that the flexible modular engine bracket is formed. The disassembled engine part is placed in the center of a steel net frame at the top of the bracket body, and then a user rotates a rotating disc on the right side of the bracket body to drive a bidirectional threaded rod located in a sliding groove to rotate; and then the sliding blocks located on the two sides of the surface of the two-way threaded rod synchronously carry the clamping plates to get close to the outer sides of the engine parts, the mode can be achieved only by rotating the rotating disc singly, and therefore a user can twist and use the engine parts more conveniently, and then the buffering assemblies located on the inner sides of the clamping plates clamp the engine parts.

This utility model provides an oil filter pressure reducing valve, including a filter connecting plate, a main housing, and an outer housing. The main housing and the outer housing are fixed to the lower end of the filter connecting plate. The main housing is located inside the outer housing, and an auxiliary cavity is formed between the main housing and the outer housing. A sealing block is fixed to the lower end of the auxiliary cavity. A second filter ring and a first filter ring are respectively embedded at the upper and lower ends of the outer housing. The main housing has a main cavity, and a fixing plate is horizontally welded inside the main cavity. This design solves the problem that the original oil filter pressure reducing valve actually uses a single spring for pressure reduction, resulting in poor pressure reduction effect after long-term use. This utility model adopts a double-spring pressure balance and magnetic damping composite structure, which can efficiently buffer the oil fluid. The use of the main cavity and auxiliary cavity structure makes this pressure reducing valve more precise.
