In the past decade, the research on graphene is hot, Graphene is also considered to be a "revolutionary material" and "the king of materials in the 21st century" because of its extremely wide application prospects in the fields of energy, biotechnology, aerospace and so on. Some experts predict that in the next 5 to 10 years, the global graphene industry will exceed 100 billion US dollars.

Graphene is much lighter than ordinary diaphragm, will quickly bounce back to the original position, in the design of almost no consideration for energy loss. Conventional loudspeakers cannot do this and require more electricity to power them. In addition, this advantage improves the frequency response curve for better sound quality.

Two years ago, scientists made graphene diaphragm Sound unit, the sound effect is very good, light and low energy consumption, based on this research technology, Montreal Canadian startup Ora Sound plans to market this technology soon, can use battery powered portable wireless diaphragm headphones to extend the battery life by 50%. To launch a portable wireless earphone that uses a graphene diaphragm sound unit.

Ora has applied for a patented technology called Grapheneq, which is composed of 98% graphene material and oxygen and other mixture, further reducing the cost, and Ora has also prepared a pre-production prototype of the transmitter unit, and is now looking to cooperate with consumer electronics companies. To use this material of the diaphragm in the headset and achieve mass production. It can effectively improve the battery playback time of portable headphones.
