DEVELOPER'S KIT OFFERING

TEST STRIPS

1cm x 3cm GrapheneQ strips for mechanical testing

BOOKSHELF SPEAKERS

3'' enclosed GrapheneQ speaker + idential Polymer speaker for A/B comparison

HEADPHONE DRIVER

40mm headphone driver for acoustic testing

CUSTOM CONES/DOMES

GrapheneQ membranes made to an OEM's specs, to test in an existing product line 

SUPPORTED USE CASES

1.FIGURE OF MERIT

GrapheneQ has a high Young’s Modulus and low density making it ideal for use in loudspeaker membranes.

2.IMPULSE RESPONSE

GrapheneQ is low mass and can move quickly. Internal damping is high, reducing ringing effects.

4.POWER CONSUMPTION

For an equivalent audio performance, GrapheneQ extends the battery life of portable audio devices.

5.DISTORTION

GrapheneQ provides improved amplitude linearity, reducing both harmonic and intermodulation distortion.

3.SURFACE SCAN

GrapheneQ reduces non-pistonic motions of the diaphragm. The high stiffness material reduces speaker break-up at high frequencies.

6.FREQUENCY RESPONSE

Directly replacing a diaphragm with GrapheneQ produces a measurable improvement in high-frequency response.

SUCCESS CRITERIA

Ora has designed this developer kit to support the following acceptance tests:

1. FIGURE OF MERIT

Produce a FoM proportional to the first bending mode of a flat disk that is greater than Aluminum.

2. IMPULSE RESPONSE

Improved transient and/or damping performance relative to paper, Mylar, Aluminum, or Titanium.

3.SURFACE SCAN

Improved pistonic motion.  Reduced speaker “break-up” relative to paper, Mylar, Aluminum or Titanium.

4. POWER CONSUMPTION

Minimum 15% improvement in efficiency (sound power output / electrical power input)  relative to Mylar, Aluminum or Titanium when exhibiting the same first break-up frequency.

5. DISTORTION

75% or less average harmonic distortion at 1kHz and above relative to paper, Mylar, Aluminum, or Titanium.

6. FREQUENCY RESPONSE

Reduced frequency response irregularities at high frequency.  Extended high frequency response for an equivalent sensitivity.
