    Technology Development

    Steve is developing proprietary transducers, loudspeakers systems, and audio test technologies.
    With patent applications in the pipeline, key technologies are available for license to strategic partners.







Technology Licensing:


Audio System Quality Verification:
A
patent pending test protocol to verify and if necessary, calibrate production automotive audio systems to match the original "tuned" system reference on which they are based.
This is motivated by work Steve Hutt has done on Loudspeaker Production Variance where variance in even "good" loudspeakers leads to system variance beyond expected acceptability.
On a parallel path, this methodology offers a viable solution to reduce loudspeaker costs, ideal for the BRIC market. 
        (see LOUDSPEAKER RECTIFICATION METHOD (Patent App. # US20110211705) and AES papers below)

Vibration Free Woofers:

- A major problem in production automotive sound is that woofer vibration induces noise by causing panels to vibrate.  This typically requires expensive mechanical reinforcement.
Vibration free woofers (no, it's not an oxymoron) can
cost effectively reduce panel noise.
Prototypes and
IP in process.

Alternatives to Neo (NdFeB) Magnet :
Rare earth materials cost is a big deal.  A true workaround for motor topologies without at least one trade off of cost,weight or size
penalty might be more rare than rare earth metals.
Prototypes developed, IP in process.

Studio Monitors:
The range of studio monitors
currently on the market exhibit near identical performance.  An alternative approach provides a strategic differentiation with performance improvement beyond the general state of the art.
Prototypes developed, IP in process.
                        



                                                    CURRENT

Steve has consulted for Audera on QMS initiatives, strategic technology development and through their Sentient Magnetics Inc. spin-off, a unique, patented electromagnetic transducer that has great potential in this neo cost sensitive era. Previously, Steve worked arms length with Audera while industrializing the THX - Razer Mako audio system for production in 2007.



nfuzion inc.

nfuzion inc. is a brilliant organization that specialize in tier 1 HMI solutions. They also have great depth in RF and audio amplifier development and have prototyped their first DSP/Class D 400 watt 12v amp with all the bells & "your door is open" whistles you could ask for. nfuzion has installed an HMI and audio system showcase in a Mini Countryman debuted at CES '12 to awesome acclaim. Steve provided transducer design and utilized proprietary vehicle tuning methodologies to "voice" their demo Mini sound. 

      Jestaco Labs - co-founder, partner 2008-2011.

Steve has developed a proprietary approach to maximize performance capability with maximal engineering efficiency. While at Jestaco Labs Steve utilized his proprietary techniques to tune (GM like to say 'calibrate') automotive audio systems while working on site at vehicle manufacturer's facilities:


 
  - Loudspeaker electro-acoustic parameter analysis
  - Cabin Acoustics analysis and tuning:
      > Time domain - impulse, ETC, Reflectograms all critical for minimum phase analysis.
      > Frequency domain data - balanced with minimum phase capability.
      > Spatial, stage, imaging, spectral & dynamic range - maximized performance
      > Subjective scoring targets have exceeded customer LiT performance requirements, and in some cases, by considerable margin.
                     Steve is no longer a partner in Jestaco Labs, LLC.

    Regen Living, Inc.

Regen Living is an eco audio/lighting start up partenered by the Noribachi and Ammunition Groups.  Steve held the role of acting Director, Audio Technology while they explored developing two iPhone/iPod audio docking systems.  Both solar powered, the Reverb is a floor standing, full blown 2.1 iPhone/iPod player and the Audio Dock is a desk top docking station/charger.  Launch targets were set for late 2010 but alas, the Regen audio products have been on hold.

Power Compression Elimination in Moving-Coil Loudspeakers by the Use of Fan-Actuated Forced-Air Cooling

The effects of heat on the performance of moving coil loudspeakers has been shown to be detrimental to sound quality and quantity by Button, Danley, Henricksen and others. This paper investigates the use of fan actuated forced air to actively remove heat from the voice coil and motor structure and includes discussion of various designs and fluids.

    Loudspeaker Spider Linearity

Loudspeaker voice coil suspensions (referred to as spiders) are traditionally made of phenolic resin impregnated textiles. The spider's function is to maintain voice coil centering in the magnetic gap, while at the same time allowing axial motion of the voice coil. Several types of spiders were compared with differing geometry and materials, with the goal of developing a spider with potentially long-linear excursion.

    Loudspeaker Litz Wire

Studies of loudspeaker components most often concentrate on the functions that add or detract from the acoustically measurable performance aspects of loudspeakers - such as cones, suspensions, or magnet and motor assemblies. On the other hand, application of litz wire into the loudspeaker design is not well documented. Yet the litz wire has a profound impact on reliability and has a propensity to cause problems such as unacceptable extraneous noise. After a review of classical theory on the vibration of strings, bars and elasticity one will surmise that understanding the vibration of litz wire is not trivial. This paper reviews a loudspeaker case study and the ramifications of using behaved and not so well behaved litz wire.

   AmbientTemperature Influences on OEM Automotive Loudspeakers

Loudspeakers used in OEM Automotive sound systems are expected to endure and even perform throughout a wide ambient temperature range. These extreme temperatures can have significant effects on suspension linearity. Loudspeakers used in automotive audio systems are analyzed at various temperatures to study how ambient thermal conditions affect performance.

    Loudspeaker Production Variance (see attachments below)

Numerous quality assurance philosophies have evolved over the last few decades designed to manage manufacturing quality. Managing quality control of production loudspeakers is particularly challenging. Variation of sub-components and assembly processes across loudspeaker driver production batches may lead to excessive variation of sensitivity, bandwidth, frequency response and distortion characteristics etc. As loudspeaker drivers are integrated into production audio systems these variants result in broad performance permutation from system to system that affects all aspects of acoustic balance and spatial attributes. This paper will discuss traditional electro-dynamic loudspeaker production variation.
