Split – The Bite-Controlled Wireless Headphone-Sized MP3 Player
Ryan Martin / 4 years ago
While wireless headphones tend to connect via something like Bluetooth, a new set of headphones from Greenwing Audio – dubbed split – is set to change that. Split is an MP3 player and set of headphones rolled into one. Pictured above the Split looks like nothing more than a pair of earbuds but in reality it is much more complex than that.
Firstly inside that tiny earbud is a small circuit board with a custom battery, memory chip, processor, accelerometer and high precision crystal clocks. The two earphones which start off magnetically attached begin to play synchonised audio when split. The earphones exchange a short near field signal when the track or volume is changed apparently reducing the radiation exposed to your head by 1000 times. The tracks and songs are changed by a biting motion where the onboard accelerometer detects the pattern of the bite – one bite skips the track and another bite changes the volume. Tapping the right earphone locks the player to avoid changes when you are eating or chewing gum. Split has a custom USB cable for recharging the onboard battery and transferring music to the onboard storage, it connects via USB 2.0.
The specifications of the Split are as follows:
- Processor: ARM Cortex M3 32bit
- Memory: NOR Flash, capacity from 64MB to 256MB
- Max Audio Output Power per channel: 20mW
- Audio Amplifier SNR: 100dB
- Speaker Type: 6mm Neodymium Dynamic Driver
- Frequency response: 20Hz-20,000Hz
- Sensitivity (1kHz): 105dB/mW
- Speaker impedance 16 Ohm
The project is currently starting up on Kickstarter and it is going to cost a hefty $155 to get your hands on a pair of these new headphones. If you want to check the new technology out then you can do so right here.
