另一個經典的電子織品原型,由導電銀漿構成的線圈圖案,被涓印在構樹紙上,首先將來自放大器的音源信號送入線圈以產生磁場,這些磁場再和置於構樹紙後面的強力磁鐵共振將振動傳送到空氣中,這些空氣的振動再傳到耳膜,一個簡單的構樹指揚聲器就完成了。決定揚聲器的品質的條件有許多,例如磁場強度的大小,基本上若導電銀漿的阻抗越低,網版線圈的圈數越多,線圈線條的寬度越寬,表示能通過線圈的電流越多,則磁場越強。另外紙張的軔性和彈性也決定了共振的品質,如太厚的綿布就比較不適合做為產生振盪的基底,通常化纖的布料共振會比較好,像是雨傘布。

Another classic e-textile prototype, a coil pattern made of conductive silver paste, is screen printed on paper mulberry sheet. Firstly a sound source signal from an amplifier is sent into the coil to generate magnetic field. These magnetic fields are combined with the paper placed behind the paper mulberry paper. The strong magnetic resonance transmits the vibrations into the air, and these air vibrations are transmitted to the eardrum, and a simple paper mulberry finger speaker is completed. There are many conditions that determine the quality of the speaker, such as the strength of the magnetic field. Basically, if the lower the impedance of the conductive silver paste, the more turn of the coil, the wider width of the coil line, indicating that more current can be passed through the coil, therefore the stronger magnetic field it is. In addition, the flexibility and elasticity of the substrate for the conductive coils also determine the quality of the resonance. For example, too thick cotton cloth is not suitable for the substrate to generate vibration. Generally, the resonance of synthetic fiber cloth will be the best option, such as the fabric for umbrella.
