A MEMS transducer (10) for an audio device comprises a substrate (12), a membrane (14) attached to the substrate (12), and a back-electrode (18) attached to the substrate (12), wherein a resonant frequency of the back-electrode (18) is matched to a resonant frequency of the membrane (14). Further, a method of manufacturing a MEMS transducer (19) for an audio device comprises attaching a membrane to a substrate (12), attaching a back-electrode (18) to the substrate (12), matching a resonant frequency of the back-electrode (18) to a resonant frequency of the membrane (14).

The embodiment of the invention provides a mobile phone fixing structure and a mobile phone, and belongs to the field of communication. The mobile phone fixing structure comprises a front shell, a part to be fixed and a covering part, wherein an elastic clamping hook and a stopping part are arranged on the same side of the front shell; the part to be fixed is connected to the front shell in a clamping mode through the elastic clamping hook, a clamping portion is arranged at the edge of the covering part, the covering part is provided with a limiting body protruding towards the elastic clamping hook, the clamping portion is connected to the stopping part in a clamping mode, and the limiting body and the elastic clamping hook are in contact at the back side of the head of the elastic clamping hook so that the elastic clamping hook can be limited. The mobile phone comprises the mobile phone fixing structure. According to the mobile phone fixing structure and the mobile phone, the parts can be conveniently mounted and dismounted through the elastic clamping hook, and the part to be fixed can be prevented from falling off when the mobile phone is subjected to high impact force.

The invention relates to a coal mine car connecting mechanism. Pin holes 4 and 5 are correspondingly formed in the two ends of a first connecting plate; pin holes 3, 1 and 2 are correspondingly formedin the two ends and the middle part of a second connecting plate; one section, with the pin holes 3 and 2, of the second connecting plate is a connecting unit; one section, with the pin holes 1 and 2, of the second connecting plate is an engaging unit; the first connecting plate is hinged with the engaging unit through a cylindrical pin 1 which penetrates into the pin holes 2 and 5; a first groove and a second groove are correspondingly formed in one side, opposite to the engaging unit, of the first connecting plate; the first groove and the second groove form an accommodating space when thepin hole 4 rotates to be coincided with the pin hole 1; a handle 2 is fixedly connected to one side of the first connecting plate; a pin locking device comprises a rotating rod, a cylindrical pin 3, aconnecting rod, a handle 1 and two connecting pieces; the two connecting pieces are fixedly connected with a mine car; one end of the connecting rod is fixedly connected with the middle part of the rotating rod; and the other end of the connecting rod is hinged with the upper end of the cylindrical pin 3. The coal mine car connecting mechanism has the advantages that the connection safety factorof the mine car can be effectively increased, the operation is simple and convenient, the labor intensity of workers can be reduced, and the working efficiency is enhanced.

The invention relates to the technical field of drilling tool machining, in particular to a special drilling bit for composite materials, which comprises a tough fixing handle, a connecting section used for extending a working area is connected beside the tough fixing handle, a machining section integrally formed with the connecting section is arranged beside the connecting section, and the machining section is connected with the tough fixing handle. The machining section is arranged to be used for machining the workpiece to be formed, the machining section can effectively prevent resistance in the drilling process, the cutting smoothness is improved, and the machining efficiency is improved.

A diffuser assembly for diffusing a liquid in irrigation plants has a supply conduit includes a diffuser with a nozzle adapted to direct a jet of liquid along a longitudinal axis, at least one deflector facing the nozzle for radially spraying the jet outwards, and a connection device for ensuring fluid connection of the diffuser to the supply conduit of the plant. The diffuser is mounted onto the irrigation plant with the axis extending in a substantially vertical direction and with the nozzle facing up, and the deflector is configured to rotate about the longitudinal axis, thereby causing oscillations in the assembly. The connection device includes a tubular body with end joints that connect to the diffuse, and the supply conduit and the body is monolithic with the joints and is made of a thermoplastic elastomeric base material. Furthermore, the body has an outer surface with annular folds, which imparts elasticity and damp the oscillations induced by the deflector. A pivot or linear irrigation plant includes a plurality of those diffuser assemblies.
