    • A flat speaker unit is provided herein. The flat speaker unit includes a first porous electrode, a second porous electrode, and a vibrating membrane with an electret layer disposed there between. In one embodiment, a plurality of supporting members may be configured between the vibrating membrane and the first porous electrode, or between the vibrating membrane and the second porous electrode. In one embodiment, a flat speaker device is provided with at least two flat speaker unit stacked together. By electrically connecting two ends of a signal source respectively to the first and second porous electrodes, or, in another embodiment, electrically connecting one end of the signal source to both of the first and second porous electrodes and connecting another end of the signal source to the vibrating membrane, a sound with low THD is generated accordingly from the flat speaker unit.
    • 本文提供了一种扁平扬声器单元。 平板扬声器单元包括第一多孔电极,第二多孔电极和其间布置有驻极体层的振动膜。 在一个实施例中,多个支撑构件可以配置在振动膜和第一多孔电极之间,或者在振动膜和第二多孔电极之间。 在一个实施例中,平板扬声器装置设置有至少两个堆叠在一起的平板扬声器单元。 通过将信号源的两端分别电连接到第一和第二多孔电极,或者在另一实施例中,将信号源的一端电连接到第一和第二多孔电极两者并将信号源的另一端连接到 振动膜,相应地从平板扬声器单元产生具有低THD的声音。

    • A planar inverted-F antenna has advantages of easy manufacture, a stable structure and automatic assembly. The antenna is fixed onto a PCB and has a grounding element that is made of conductive material and is plate-shaped, a radiation element formed from a plate-shaped metal plate, a signal link element and at least one supporting leg. The radiation element has a grounding leg that electrically connects with the grounding element. The signal link element electrically connects with the radiation element to a circuit for wireless signal transmission and reception. The at least one supporting leg is downwardly bent from an edge of the radiation element far from the grounding leg and is fixed onto the PCB. The supporting leg and the grounding leg support the radiation element together.
    • 平面倒F天线具有制造容易,结构稳定,自动组装的优点。 天线被固定在PCB上,并且具有由导电材料制成且为板状的接地元件,由板状金属板,信号连接元件和至少一个支撑腿形成的辐射元件。 辐射元件具有与接地元件电连接的接地支脚。 信号链路元件与辐射元件电连接到用于无线信号传输和接收的电路。 所述至少一个支撑腿从所述辐射元件的边缘向下弯曲远离所述接地腿并且被固定到所述PCB上。 支撑腿和接地腿将辐射元件支撑在一起。
