摘要： There is provided a speaker or a speaker system which has no chance of disabled ventilating air in a space enclosed with a voice coil bobbin to outside of the magnetic circuit through a throughhole C formed in a magnetic circuit to communicate with the space enclosed with a voice coil bobbin, even if mounting a speaker between inner surfaces of a casing, because of enabled ventilating air from a space enclosed with a voice coil bobbin to outside of a magnetic circuit through an air path 3c formed in the magnetic circuit to communicate with the throughhole C.

摘要： A portable power tool such as a portable circular saw is provided with a sawdust collection system based on the generation of an air flow resulting from rotation of a rotary cutting blade, with this air flow being guided to transport sawdust resulting from cutting operations along a guide path through a first discharge aperture into a dust box in which the sawdust is precipitated, with a low-velocity air flow then passing out of the dust box through a second discharge aperture to be recirculated through the flow path. Extremely effective dust collection is attained with a simple configuration, while the dust box can be positioned such that the weight of accumulated sawdust therein does not significantly affect the balance or ease of operation of the portable power tool.
摘要翻译：便携式电动工具例如便携式圆锯具有锯屑收集系统，该系统基于由旋转切割刀片的旋转产生的空气流的产生，该空气流被引导以沿着导向件的切割操作运送锯屑通过第一放电孔进入到其中沉淀有锯屑的灰尘盒中的低速气流，然后通过第二排放孔从集尘箱中通过，以通过流路再循环。以简单的结构实现了非常有效的集尘，而集尘箱可以定位成使得其中累积的锯屑的重量不会显着影响便携式电动工具的平衡或易于操作。

摘要： A power tool comprising a brush holder assembly formed of a plastic material, a printed circuit board and a positioning member for positioning the terminals of a switch and a power cable in contact with the printed circuit board. The brush holder assembly includes a pair of spaced apart arm portions each carrying a brush for making contact with the commutator and a web portion. In each of the arm portions of the assembly is embedded a pair of conductors each having a terminal at one end thereof for making electrical contact with a corresponding terminal of the stator, the other end of each conductor making contact with the printed circuit board. The printed circuit board is provided with a conductive pattern which permits the terminals of the switch and power cable to be mutually connected and further permits them to be connected to the conductors of the brush holder assembly to complete a series circuit.
摘要翻译：一种电动工具，包括由塑料材料形成的电刷架组件，印刷电路板和用于定位与印刷电路板接触的开关端子和电源电缆的定位构件。电刷架组件包括一对间隔开的臂部分，每个臂部分带有与换向器和腹板部分接触的刷子。在组件的每个臂部分嵌有一对导体，每个导体的一端具有端子，用于与定子的相应端子电接触，每个导体的另一端与印刷电路板接触。印刷电路板设置有导电图案，其允许开关和电力电缆的端子相互连接，并且还允许它们连接到电刷架组件的导体以完成串联电路。
