HiWave launches audio platform for next-gen headsets

HiWave Technologies has introduced the Farina platform, a combination of bending wave transducer and electronics the company claims revolutionises the way audio signals are delivered to the listener.

When mounted onto the frames of spectacles, such as those used for 3D gaming, the Farina transducer stimulates the outer ear, or pinna, with a broadband audio signal, turning the spectacles into headsets. The user then hears via a fusion of airborne sound and soft tissue conduction into the inner ear.

There are potential health benefits too. In-ear 'buds' have been reported to cause long-term hearing damage due to high sound pressure levels that are created close to the eardrum. Farina technology does not generate damaging pressure transients inside the ear. Where glasses are not needed, the platform can also be used to produce other types of headset.

Farina transducers effectively turn the ear into a micro-loudspeaker but do not block external sounds that are received in the normal way via the ear canal. The technology is ideal for sensory-immersive applications such as multiuser gaming, and augmented and virtual reality. It also provides safety benefits for sportsmen such as cyclists because they can enjoy music on the move whilst maintaining complete awareness of their surroundings, including approaching cars.

HiWave's expertise in low-power audio will now be extended into semiconductors that combine audio signal processing, high-efficiency amplifier technology and high-voltage drive for piezoelectric transducers.

HiWave is currently demonstrating proof of concept to large companies and will have production-ready transducers available in Q4 2012. The Farina ceramic vibrating beam measures 25mm x 3mm x 0.6mm and delivers a multioctave audio frequency range with strong bass and clear mid-to-high frequencies.
