The appearance design and technology of earphones have not changed much over the years, but at the 2015 New York Design Week, an ultra-thin earphone that can be cleaned and the internal circuit is visible has attracted peoples attention. This ultra-thin headset does not use a single wire, and all lines are printed directly, which simplifies both the use of materials and the production process to the maximum extent. The plastic parts are also directly welded without using connectors, and the shape is not injection molded but uses low-cost embossing technology.
The working principle of the speaker is also very different from that of traditional headphones. It is based on piezoelectric sensor vibration technology that produces piezoelectric phenomena on the plastic surface. The sound quality of this headset is no better than that of traditional headphones. The headphones are poor, but the thickness is only 1mm, and the circuit wiring inside is clear at a glance. The entire headset consists of only 8 parts, which is much simpler than the dozens of components of traditional headsets. Only one side of the earphones has wires printed on it to power the speakers on both sides. The Bluetooth headset battery part also uses printed lithium battery and printed photovoltaic cell technology, and electronic components are also printed on the surface.
