摘要： Provided are an interdigitated electrode (IDE) for an electronic device, which includes a plurality of anodes and a plurality of cathodes arranged radially in an alternating fashion for electrical insulation from one another, and an electronic device using the same. The IDE in which the anodes and the cathodes are arranged radially in an alternating fashion is fabricated and applied to the electronic device, so that the entire fabrication process can be simplified compared to that of a typical electronic device in which an upper electrode is different from a lower electrode. Also, circular or polygonal IDEs can be applied to systems that are driven or measure values on their central axes, thereby enhancing the performance and efficiency of the systems. Furthermore, the circular or polygonal IDEs can be employed in systems such as acoustic sensors, pressure sensors, micro-speakers, biological sensors, and acceleration sensors, so that the structure and operation of the systems can be simplified.

摘要： In a folding-type directional speaker array module, when sound is output, the directionality of a high frequency band can be obtained through a center speaker module and the directionality of a low frequency band can be obtained through side speaker modules unfolded from both sides of the center speaker module. Accordingly, the speaker array module has excellent directionality in an entire frequency band. Furthermore, the folding-type directional speaker array module has high mobility and portability because the side speaker modules are folded and stored when the folding-type directional speaker array module is not used.

摘要： In a piezoelectric speaker, an acoustic diaphragm is thicker than a piezoelectric thin film and is formed of a more flexible and higher elasticity material than the piezoelectric thin film, thereby greatly improving output sound pressure in a low frequency band and reducing sound distortion. Further, the piezoelectric thin film is attached to the acoustic diaphragm in an inclined structure in which the piezoelectric thin film is horizontally turned from the acoustic diaphragm, thereby preventing a standing wave from being created by structural symmetry and minimizing sound distortion.
