Speaker advantages

Better Heat Dissipation

GrapheneQ can be tuned to move heat away from the voice coil for better power handling.

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.

Smaller, Louder Speakers

GrapheneQ enables the design of smaller speakers without comprimising loudness or quality.

Greater Sensitivity

 GrapheneQ can produce louder drivers that require less energy. 

Better Heat Dissipation

 GrapheneQ can be tuned to move heat away from the voice coil for better power handling.

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 #2

INCREASE THE BATTERY LIFE OF WIRELESS AUDIO DEVICES

GrapheneQ produces more efficient drivers that extend the battery life of portable audio devices

GRAPHENEQ VS. MYLAR: FREQUENCY RESPONSE

Directly replacing the Mylar membrane with GrapheneQ produces a measurable increase in sensitivity, up to 10db.

      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.
