    • The present invention relates a speaker having a diaphragm around the rim of a frame on the speaker for disposing a magnetic member at the center of the diaphragm along the direction of a resonant space enclosed by the diaphragm and the frame. When a winding in the center of the frame is excited, the resonant space generates varying magnetic lines and an attraction-repulsion effect is generated in the center of the winding or a reserved space at the position of the periphery to vertically slide the magnetic member and cause the diaphragm to vibrate and generate sound. The present invention can effectively reduce the space occupied by the components such as the seat, core, and magnetic member, and greatly reduce the thickness of the speaker.
    • 本发明涉及一种扬声器,其具有围绕扬声器的框架的边缘的隔膜,用于沿着由隔膜和框架包围的谐振空间的方向将磁性构件设置在隔膜的中心。 当框架中心的绕组被激发时,谐振空间产生变化的磁线,并且在绕组的中心产生吸引斥力效应或在周边位置处的预留空间以垂直滑动磁性构件, 导致隔膜振动并产生声音。 本发明可以有效地减少诸如座椅,铁芯和磁性构件的部件占据的空间,并且可以大大减小扬声器的厚度。

    • A utility pliers includes a first handle member (21) with a fixed jaw (211) secured to an end thereof, a second handle member (22), and a movable jaw (28). A connecting block (25) includes a first part (251) pivoted to the end of the first handle member and a second part (253) pivoted to the second handle member. The connecting block further includes a slot (254) defined therein. Two follower blocks (26, 27) are mounted to both sides of the connecting block. A pin (258) is extended through the follower blocks and the slot of the connecting block to guide sliding movements of the follower blocks along the slot relative to the connecting block. The movable jaw (28) is connected to the follower blocks to move therewith.

    • The present invention is to provide an audio radiation type reflective sound box structure, which comprises a hollow cone tube having a first end received in a box, a second end extended out of an opening of the box to form an inclined side wall, and at least one vent disposed adjacent to the first end. When a diaphragm of a speaker mounted on an inner side edge of the second end generates vibrations, compressed air in the hollow cone tube is pushed out of the opening through the vent, and then collides with the outer edge of the inclined side wall and is diffused toward a peripheral direction adjacent to a front side of the speaker along an extension direction of the inclined side wall. Thus, the sounds reflected by the box can be evenly transmitted to a peripheral environment adjacent to the front side of the speaker.
    • 本发明提供一种音频辐射式反射式音箱结构,其包括中空圆锥管,该中空圆锥管的第一端收容于盒体内,第二端伸出盒体的开口以形成倾斜侧壁, 至少一个排气口邻近第一端设置。 当安装在第二端的内侧边缘上的扬声器的振膜产生振动时,中空锥体管中的压缩空气通过通气口被推出开口,然后与倾斜侧壁的外边缘碰撞, 沿倾斜侧壁的延伸方向朝向与扬声器的前侧相邻的周向方向扩散。 因此,箱子反射的声音可以均匀地传输到与扬声器正面相邻的外围环境。

    • Disclosed is a flexible foil (4) including a thin and flexible foil that isolates electromagnetic waves. The foil has a smooth surface (41) and an opposite surface on which a plurality of three-dimensional raised projections (42) is formed and consecutively lined up. A slicing-facilitated, flexible thinned layer (43) is formed between adjacent ones of the projections. The foil can be deflected to enclose an electronic device that generates electromagnetic waves with the projections facing the electronic device so that the electromagnetic waves are confined inside the enclosure formed by the foil arid dispersed and dissipated by reflection and diffraction in multiple angles caused by the projections so as to prevent leakage of electromagnetic waves and to protect electronic components close to the electromagnetic wave generating device from interference by the electromagnetic waves.
