A support chassis mounted on a sounding side of a speaker apparatus is formed of an iron material. The support chassis is formed in a shape in which a central supporting part nears a main-body chassis. A magnetic field generating unit is fixed to the central supporting part on a side of a recess of the support chassis. The support chassis includes a frame part, the central supporting part, and spoke parts. In the spoke part, a width dimension D1 of an inner end part is formed narrower than a width dimension D2 of an outer end part. Therefore, a resistance in a case where a magnetic flux passes through the spoke part increases, and the leaked magnetic field is hardly induced from the magnetic field generating unit to the spoke part. Therefore, a reduction in a speaker output can be prevented.

A wholly automatic decelerating clutch and a washing machine thereof pertain to washing machine technical field; an output shaft of the wholly automatic decelerating clutch consists of a small whirlpool agitator shaft, a large whirlpool agitator shaft and a dewatering shaft that are sleeved concentrically; the whirlpool agitator of the washing machine adopting the wholly automatic decelerating clutch is a small whirlpool agitator and a large whirlpool agitator, wherein the small whirlpool agitator is fixedly arranged on the small whirlpool agitator shaft and in the center part of the large whirlpool agitator, and the large whirlpool agitator is fixedly arranged on the large whirlpool agitator shaft, and an inner bucket is fixedly arranged on the dewatering shaft. The washing manner of thewashing machine adopting the wholly automatic decelerating clutch is that: the small whirlpool agitator, the large whirlpool agitator and the inner bucket are mutually, reversely and bidirectionally rotated to and fro at a certain ratio, different speeds and different rotating angles, to produce complicated, vertically and horizontally crossed impacting water flow, to strike and rinse clothes, and fully roll, strongly rub and sway the clothes, thus improving the cleanness rate of clothes and not twisting the clothes; when the clothes are dewatered, a torsional spring automatically integrates the decelerating clutch into a whole, and decenters and dewater the clothes in high speed, without needing a whole set of clutch parts and operating mechanisms of the normal decelerating clutch.

The invention relates to a constant-rotating connection rod head of a civil air defense door. The constant-rotating connection rod head of the civil air defense door comprises a rod connecting portion and a part connecting portion, so that a rod body and a part are connected, and power driving is achieved. The constant-rotating connection rod head of the civil air defense door is characterized in that the side, making contact with a door panel, of the rod connecting portion is provided with a plane where the cylindrical rod body is arranged, the cylindrical rod body is located in a specific track slot in the door panel, and the connection rod head is limited from rotating in the axial direction of the rod body. Thus, abrasion between the part connecting portion and the part is reduced, and driving resistance is reduced.

The present invention provides a magnetic gear, which includes a gear body and a magnetic source. The gear body includes a first gear body and a second gear body, a first magnetic source array is uniformly distributed along the circumferential direction of the first gear body, and a second magnetic source array is uniformly distributed along the circumferential direction of the second gear body. Along the axial direction of the gear body, the first magnetic source of the first magnetic source array cooperates with the middle of the second magnetic source of the second magnetic source array to produce an attractive force; the two ends of the first magnetic source and the second magnetic source cooperate to produce repulsion respectively. force. In the working position, repulsive force and attractive force are simultaneously generated between the magnetic source and the magnetic source. The repulsive force is generated at both ends of the magnetic source, the driving force for driving the driven gear to rotate by the driving gear is improved, and the stability of the transmission between the gears is improved. Through the attractive force generated in the middle of the magnetic source, the phase alignment when the gears are engaged with the gears is realized, and the reliability of the gear engagement is improved.

A decelerating clutch of a washer and the washer and a washing mode thereof relates to the technical field of washers. An output shaft of the decelerating clutch includes a small wave wheel shaft, a large wave wheel shaft and a dewatering shaft. By adopting optimized inner structure design, the invention can simultaneously drive the larger and the small wave wheels to rotate actively, and a brakewheel is directly connected with the dewatering shaft and an input shaft sleeve, thus reducing the production cost. A washer manufactured by using the decelerating clutch comprises a small wave wheeland a large wave wheel, wherein the small wave wheel is fixedly arranged on the small wave wheel shaft and positioned at the middle portion of the large wave wheel; the large wave wheel is fixedly arranged on the large wave wheel shaft; and an inner barrel is fixedly arranged on the dewatering shaft. The washer manufactured by using the decelerating clutch is operated in such a mode that the small wave wheel, the large wave wheel and the inner barrel make reciprocating rotation in mutually reverse directions at different speeds and different rotation angles by a ratio in two directions to produce complex and crossing shock water flow to scrub and clean the clothes, thus completely rotating the clothes, achieving strong scrubbing force, improving the cleaning rate and preventing twisting of the clothes.
