Speaker advantages
Greater Sensitivity
GrapheneQ can produce louder drivers that require less energy.
Greater Sensitivity
GrapheneQ™ can produce louder drivers that require less energy.
Extended Frequency Response
GrapheneQ™ membranes are lighter and can move fast while requiring less damping in the lows.
Lower Distortion
GrapheneQ™ pushes speaker “break-up” to super-sonic frequencies producing superior sound quality.
Better Heat Dissipation
GrapheneQ can be tuned to move heat away from the voice coil for better power handling.
Smaller, Louder Speakers
GrapheneQ™ enables the design of smaller speakers without compromising loudness or quality.
Better Heat Dissipation
GrapheneQ™ can be tuned to move heat away from the voice coil for better power handling.
OPPORTUNITY #1
IMPROVE THE SOUND QUALITY OF AUDIO DEVICES
NORMALIZED FREQUENCY OF FIRST BENDING MODE RELATIVE TO MYLAR
The first bending mode of GrapheneQ paper is at least three times higher than Mylar.

OPPORTUNITY #3
THERMAL CONDUCTIVITY ENABLES HIGHER POWER HANDLING
A REDUCED-GRAPHENEQ MEMBRANE AND FORMER
SAFE OPERATIONAL RANGE OF A MICRO LOUDSPEAKER
The operational range of micro speakers is directly limited by the speaker's ability to dissipate heat. Improving thermal conductivity in the former and membrane will help move heat away from the voice coil, improving the power handling of these devices.
Reduced-GrapheneQ™ is thermally conductive, helping to move heat away from the voice coil, minimizing speaker damage. A reduced-GrapheneQ™ speaker would also be lighter and more efficient, further increasing the speaker's output capacity.
