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.
