NEW YORK (CONVERSEER) – Startup Sensia Technology showcased a portable fabric speaker last week (9 December), equipped with flexible electronics that allow sound to be emitted evenly across the entire fabric surface, enabling a diverse user experience.
According to IT Home, the speaker’s fabric is woven from flexible conductive fibres and uses a capacitor-like structure, so the entire surface of the fabric can produce sound.
The working principle is similar to that of an electrostatic speaker. It forms a large-area ultra-thin capacitor through two conductive layers and an ultra-thin dielectric film in the middle. When the audio signal modulates the electric field between the conductive layers, the fabric vibrates, pushing and pulling the air to form sound waves that can be heard by the human ear.
For reference, traditional concealed speakers such as pillows and cushions generally rely on closed-back drivers. The speaker placement of these products usually has a noticeable protrusion, and the listening effect often depends on whether the user places them in the correct position.
In contrast, this speaker is positioned as a hidden listening device, which the company claims can be hung on the wall like a tapestry or placed under a pillow or sheet.

Meanwhile, we can see that this speaker has a plastic component on the side, which integrates a compact driver circuit, a battery, and a wireless connection module. Its maximum volume can reach 68dB, and it can be boosted to 71dB when used in pairs. The volume level is close to the noise of a vacuum cleaner or a washing machine during spin drying.
However, the official specifications do not provide information on the speaker’s sound quality, so we currently do not know whether this speaker is a new toy for audiophiles or an innovative experimental product.
