President's Message

What you missed at the ALMA Symposium in China and reasons to attend the ALMA Symposium in Las Vegas

What does China mean to you?
Is it an exciting new market or a competitive threat?

I was recently in Asia for the ALMA Symposium in China and to visit customers. I have visited many loudspeaker manufacturers in China the past few years and I am always amazed how fast the economy and infrastructure are growing. For example in Beijing, people are trading in their bicycles for cars at an alarming rate causing traffic jams and pollution. Virtually every company I visit is expanding and building new facilities causing raw material, water, and energy shortages.

I have noticed a few trends which may be of interest to my fellow ALMA members. For one, Chinese factories are making loudspeakers for many different leading brands of US and European loudspeaker companies. It is always a little surprising to see competitive brand loudspeakers sitting on a display shelf next to each other in the visitor's conference room. One must assume that there is a degree of cross-pollination between designers and manufacturers that is unavoidable. What strategies are there to continue to keep brands differentiated in this environment? In contrast, Korean, Taiwanese and Japanese loudspeaker companies tend to setup their own factories in China.

There also seems to be an increased interest in automated manufacturing and testing. Chinese manufacturers are taking quality very seriously. They realize that quality is what matters to users since price is already low. Even though China has nearly the cheapest labor in the world, they realize that ultimately, automation will keep manufacturing costs down and ensure they remain price competitive.

Even though Chinese companies manufacture for many different overseas companies, they want to engineer and market their own brands. It can be considerably more difficult for foreign designers and local manufacturers alike to safeguard intellectual property in this less regulated environment. Chinese companies are learning the latest technology like Bluetooth to develop their own Bluetooth headsets.

Everyone in this industry is affected by one or more of these issues and, like it or not, you have to accept that China is a global force in the loudspeaker business. We all need to figure out the best way of increasing and/or protecting our businesses. ALMA facilitated this by holding its first ever ALMA show in Asia in Guangdong, China October 16. We had a great turnout and a great discussion about "Closing the engineering gap between Asian suppliers and Western customers". My favorite question from one of the Chinese attendees to Pat Turnmire, the keynote speaker, was "How do we make our products better and still make them cheaper?"

ALMA continues to explore international business with Asia by holding its first ever Manufacturer's Roundtable Discussion at our annual winter symposium in Las Vegas, January 4 & 5. With this year's focus on quality and reliability, the discussions will center on developing strategies on how to operate our businesses with key vendors, customers, and factories on the other side of the globe.

What can you gain by attending the ALMA symposium in Las Vegas?

Over 20 companies will be exhibiting products that can improve your product, reduce your costs or facilitate your manufacturing process. The Symposium will also feature a training course by the renown Dr. Earl Geddes on "Loudspeaker System Theory" presentations and papers on topics such as distortion, dynamic measurement on loudspeaker suspension parts, "Life after Kapton", standards meetings and roundtable discussions on global business strategies. ALMA takes place right before the CES Show so you can also attend that to find new customers, vendors and partners, as well as see all the latest gadgets. There is a large group of Asian audio manufacturers and suppliers grouped together at the Hilton. Watch your email for information on how you can be part of this informative symposium.

Managing Director's Message

Welcome to this issue of ALMANews. A lot has happened with ALMA since our last newsletter! We  are pleased to report that we had a very successful first - ever international Symposium in China in October. This was a valuable opportunity to meet with  prospective members and vendors from China, and for all attendees to  hear Patrick Turmire's informative presentation on "Closing the Engineering Gap Between Asian Suppliers and Western Customers". To have an international meeting was a goal in ALMA's strategic plan, so seeing this come together, with a good turnout and excellent educational program is a great way to round out 2004.  In addition, ALMA also  hosted a networking reception in San Francisco during the AES show in October. It was another opportunity for ALMA members and industry colleagues to get together and network.

We are well underway for our Winter Symposium in Las Vegas. We will again be at the Tropicana Resort & Casino on January 4-5. If you have not registered yet, please do so as soon as possible. You can download the registration forms, as well as view the entire program, on our website, www.almainternational.org or email me at management@almainternational.org. If you are interested in exhibiting, there are a few booth spaces still available, so contact ALMA Headquarters as soon as possible to be sure you get a space.  Lori and I are looking forward to a great event and registrations are pouring in each day.  

We look forward to seeing you all in Las Vegas!

Best regards,
Lynn McCullough

ALMA's First-Ever International Symposium in China was a Huge Success...

ALMA embarked on its first ever international Symposium on October 16, and it was a tremendous success. The Symposium themed, "Closing the Engineering Gap Between Asian Suppliers and Western Customers" was attended by more than 70 industry colleagues from China, USA, Germany, and Korea. The Keynote presentation given by Patrick Turnmire of Redrock Acoustics focused on the theme, and was well received by the attendees.

The program also included tutorial presentations on non-linear modeling using the Klippel Analyzer, SpeaD / Reverse SpeaD, production testing using SoundCheck by Listen and finite element modeling of cones using Loudsoft.

Special thanks goes out to ALMA Board member, Peter Huang of Superior Sound Technology of Fugian, China for his efforts in making this Symposium a success.

Standards Report

By Dan Field

Most of the time, the work of standards bodies tends to be somewhat dry; and the results are of interest only to the few people whose lives are made easier by the existence of common measurements. No need to reinvent the wheel; a clear path towards accurate measurements; and a common basis for comparison. And then there are loudspeaker standards. Loudspeaker standards are different. Take for example the years-long discussion of Xmax (see last quarters ALMANews standards report at http://www.almainternational.org/content/almanews/ANv11_1.pdf). Obviously, the commercial interest in having a "magic number" tends to work against the engineering need for a completely descriptive data set.

Now comes a revisiting of the CEA-426-B standard in view of a rapidly changing landscape in the mobile sound industry. We contacted Andy Wehmeyer of Harman Consumer Group who filled us in on the CEA's R6 Mobile Audio Division standards group activities. Andy is co chair of the committee (along with Audiovox's Steven Okurowski), which has appointed a new working group (WG13) having the following mission statement:

R6 WG13 addresses power-handling ratings of mobile speakers in general and subwoofers in particular by defining testing and rating procedures and ratings disclosure requirements.

Andy and the committee sees a changing market force where "Big Power has gotten cheap", owing to the existence of Class D amplifier power. It is now not uncommon to see amplifiers rated in kiloWatts. This is not a problem for loudspeakers if the power is distributed across a dozen or so woofers. However the customer's desire is to package fewer loudspeakers and still reap the benefits of the high power amplifiers. The result is fractional ohm loudspeakers that can pull (and withstand) many hundreds of Watts.

 While the CEA 426-B standard  (which we all know and love)  satisfies the needs of most  loudspeaker applications, the group  believes it doesn't work that well for  the mobile audio consumer. The  biggest difference according to  Andy is that the customer needs to  know how loud a loudspeaker will  play, and how much power is  needed to drive it to those levels.  This adds in an SPL reference  which is not contained in the 426-B  spec. The working group plans on  matching up the recently completed  CEA-2006 standard for measuring  amplifier power, with this new  proposed standard; so that the two  of them together can paint a more  complete picture for the customer.

The WG is open to any member of CEA with an interest. For more information, please contact Andy Wehmeyer at awehmeye@harman.com.

Ask Andy - Asks the Members

Hello all,

I have just had a conversation with a representative of the US Patent and TM Office (USPTO) about using information provided by our Association membership during a search for prior art.

The USPTO representative does not wish to have the substance of that conversation posted here and wishes to remain anonymous, but we did explore the idea of giving the USPTO access to this forum so that questions relating to prior art publications showing a given structure or method could be posted for the membership to answer.

A number of practical issues surfaced. First, if the USPTO representative is given a membership with a user ID and password, how can the identity of the USPTO representative and the identity of the patent applicant be protected?

By law, patent applications are to remain secret until published by the USPTO and the USPTO can divulge status info only to owners and attorneys of record, so does an inquiry to the Association divulge too much? How would you feel if it were about your application?

Since anyone can provide information in response to a USPTO request, how will that information be authenticated?

If an Association member has one or more claims in a patent application rejected over prior art provided from an ALMA forum member, should the anonymity of the ALMA forum member be protected? If so, who can testify as to the authenticity of the prior art document if it's not a US patent?

During our meeting last January, we discussed the Association's interest in having, preferably, only valid patents issue; this means the patent examiner needs to consider all relevant prior art. How can the Association communicate about prior art and make that prior art available to the patent examiner? Would using this forum be preferable to e-mail inquiries?

We need to know your views on this topic.

Thanks,
Andy

Audiomatica recently released the new software CLIOwin 6.5, a professional suite to execute electro-acoustical measurements under the Windows operating system. The support for the Microsoft operating system is now complete ranging from Windows 95 to Windows XP. The different versions of the software satisfy most different needs, from version Lite, perfect for the hobbyist and novice user, to version Standard, the professional choice for laboratory measurements, up to version Quality Control that is able to manage a production line. Of particular interest are the new possibilities to manage the Audiomatica hardware SC-01 (Signal Conditioner) e QCBox Model 4 (Amplifier and Switch Box). The basic hardware of the CLIO system relies on the PB-4281 PCI card together with the external unit SC-01 that performs the correct analog interfacing with the electrical signals to be measured; among the excellent specifications of this analyzer we find a two channels architecture, handling of input signals ranging from +40dBV (283V pp. max.) to -40dBV full scale, with 18 bit acquisition precision and an incredible dynamic range totaling over 160 decibels, signals generation with amplitude variable in precise 0.1dB steps and with the possibility of superimposing a DC voltage thus rendering possible sophisticated analysis of electro-acoustical transducers. Internally, it also presents a very high precision voltage reference that permits an ultra stable auto calibration and, upon request, the calibration certification against national and international standards. Last but not least, the new amplifier and switch box QCBox Model 4 represents the natural complement of the CLIO analyzer in any laboratory. It has 50W (8Ohm) output power, 4 input channels with microphone power supply and permits the output current sensing oriented to impedance measurements at variable amplitudes and current distortion measurements. Using a particular adapter panel (Rack QC), it is possible to assemble the SC-01 unit together with the QCBox Model 4 in a unique 19” standard Rack unit for fixed installations like along production lines.

Beyma will present new models at the PLASA 2004 Trade Fair with its solution for Line Array design as the main innovative product. The new items included in the Beyma 2004 catalogue provide a response to the growing demand for very light and powerful loudspeakers.

The greatest innovation is the WL5, which Beyma launches to the market as the best solution for the high frequency design of Line Array Systems. This model is composed of two components:

- A specially designed high frequency compression driver, based in the outstanding CP-755/ND but in a much more compact size for optimum assembling, with 108dB and 80 W AES.

- And a simple but effective wave guide which transforms the circular aperture of the compression driver into a rectangular surface, without excessive angle aperture to provide minimum vertical dispersion to the acoustic wavefront.

The design fulfills the curvature requirement for optimal acoustic coupling between adjacent sources up to 16 kHz. The wave guide is 5" tall and 1" width, and it can be coupled to the horn with the dispersion required by the system designer.

Finally, the new ND LW30 Family presented in Frankfurt is available from now on to all of our custumers. With sizes ranging from 8" to 15", this series of speakers is distinguished for being lightweight, although powerful at the same time (from 250 to 500 W AES), specially conceived for high quality sound systems, from Line Arrays to compact two-way boxes.

The SM family renovation will finally be completed with the new high frequency models:

•  The SMC-60 is a high frequency compression driver with 2" mouth diameter, with similar characteristics to the Pro model CP-750/Ti, but with a more compact size and adjusted price. The main improvement respect to the substituted model SMC-55 is an extended high frequency response and sensitivity. 109 dB, 1W@1m and 90 W AES.

•  The SMC-2012/N is a completely new design concept. It is composed of a high sensitivity tweeter, with a supronyl material dome of excellent damping properties, together with a small compact horn for controlled directivity. The neodymium magnetic structure makes this tweeter extremely sensitive, 101 dB 1W@1m, with a coverage angle of 50ºHx35ºV. This converts this model in a high efficient tweeter, similar in sensitivity to a compression driver, but with the clarity and crystalline sound of a high fidelity tweeter.

•  The SMC-1050/N is the evolution of the SMC-1050, with higher efficiency and extended high frequency response.

•  And finally, the SMC-1020 model disappears, and it arises a new model, with the same conception of compression driver with horn to an affordable price, but with superior characteristics: bi-radial compact horn design, lower distortion and extended high frequency response.

All these novelties will be available at Beyma's web site (http://profesional.beyma.com/ENGLISH), and they will be exposed in the PLASA 2004 Show.

ALMA members Ferrotec (USA) Corporation and Menlo Scientific, Ltd. announce the establishment of a collaborative test and measurement facility located at Ferrotec's US headquarters in Nashua, NH.

"Menlo had been looking for a larger space to house its lab and Ferrotec was interested in expanding their testing capabilities", explains Mike Klasco, President of Menlo Scientific. "Given the long standing relationship between Menlo and Ferrotec, this was an easy decision to reach and one that benefits both companies."

The lab will be used to support customers and clients of Ferrotec and Menlo as well as to support ongoing audio ferrofluid development projects by Ferrotec. It will be staffed by industry veteran Steve Tatarunis who is currently a Sr. Engineer with Menlo and a former Ferrotec employee.

"We're very happy to maintain our relationship with Menlo and with Steve through this collaboration", says Barry Moskowitz, Vice President of Ferrotec. "Steve is intimately familiar with our products and the addition of Menlo's test and measurement equipment to our audio lab significantly upgrades our ability to serve our customers and support our own internal product development efforts. This is a classic example of a 'win-win' situation."

K & K International ApS has introduced two new acoustic test systems, the P630 and P730 for testing of loudspeaker units, loudspeaker systems, and headphones. Furthermore the P630 can test telephone handsets and microphones.

The P630 system consists of a P600 cabinet, two PC boards for PCI bus and software for windows 2000 and XP. The user interface is the same as P530. A P500 cabinet can be used together with a P630. This enables an easy upgrade to a P630. The two PC boards consist of an IO board to control of functions inside the cabinet and of a quality soundboard. The P630 makes use of inputs 4 and 2 outputs, 24 bits and with a sample frequency of 96 KHz to ensure a fast test.

There are two versions of P730. P730 Picro Std (standard) and P730 Picro Pro.

P730 is a fast and cost-effective test system with many functions as in P530.

P730 Picro test systems makes use of a USB Audio Capture UA-5 unit with a resolution of 24 bits and sample frequency of 48 KHz. P730 Picro Pro have as option extern control functions via a USB I/O box. P730 Picro Std is a reduced version of the P730 Picro Pro with less performance and functions. More information can be found on www.kk-int.dk

Klippel announces new developments of the KLIPPEL ANALYZER SYSTEM - the tool for measuring speakers in the small and large signal domain.

The LSI BOX Module measures the large signal parameters of drivers in loudspeaker box systems. The effects caused by the box enclosure are considered by the model which removes the need to dismount the driver for testing.

The LSI TWEETER Module extends the resonance frequency range considerably. This makes testing midrange drivers and tweeters now possible.

Recently announced modules are the MATH SCRIPT Module providing user programmable high level scientific post-processing and the SIMULATION 2 Module. The later incorporates nonlinear electro-acoustical and thermal modeling that is used to simulate the large signal behavior of drivers as well as closed box, vented box, passive radiator and bandpass systems. Forced air convection cooling is considered in the thermal modeling. The crossover, cone vibration, radiation and room frequency responses (measured or calculated) may be imported and incorporated into simulation.

For more information, specifications, price list and an extensive technical background please visit http://www.klippel.de/ or contact us at info@klippel.de.

Listen, Inc. delivers cutting-edge measurement performance using National Instruments' new PXI-4461 Data Acquisition Board with SoundCheck™

The PXI-4461 module features 24-bit delta sigma converters that deliver nearly 120 dB dynamic range over an input bandwidth of 92 kHz at 204.8 kS/s. Its two differential output channels generate frequencies up to 92 kHz, making it ideal for stimulus response tests such as swept-sine. To ensure the highest accuracy for precision audio measurements, the PXI-4461 dynamic signal acquisition module includes differential inputs, anti-aliasing protection and integrated electronic piezoelectric (IEPE) conditioning for microphones and accelerometers. www.ni.com/pdf/products/us/pxi4461.pdf

To speed development of audio test applications, engineers can combine the PXI-4461 module with Listen's SoundCheck software to accurately measure frequency and phase response, harmonic and intermodulation distortion, THD + Noise, impulse response, and a wide variety of other audio performance metrics. Engineers now can simultaneously generate and acquire high-accuracy dynamic signals for electroacoustic and audio electronic measurements.

NXT announced that TVR, the specialist sports car manufacturer based in Blackpool, England, will use NXT's audio full range (AFR) solutions in four models in its range. This is the first time NXT technology will be commercially available in a vehicle and represents an important first for the company.

Two mini NXT AFR units will be used in each of the TVR Tamora, Tuscan, T350 and Sagaris. The NXT AFR units will be dash or door mounted, depending on the model, and will be paired with conventional woofers to complete the loudspeaker system.

NXT AFR is a loudspeaker drive unit that offers broad frequency response with minimal footprint. It does this by combining the desirable properties of a piston at low frequencies with those of NXT modal operation at mid and high frequencies.

This patented technology is proprietary to NXT and offers car manufacturers a number of crucial benefits:

- Unlike conventional drivers, which tend to beam sound particularly at higher frequencies, NXT AFR units distribute sound evenly across their pass band, providing a much more even listening experience to both the driver and passenger.

- In addition, because the diaphragm is planar, the depth of the NXT AFR is significantly reduced. This enables the units to be placed higher up in the vehicle's interior, lifting the sound stage as a result.

- NXT AFR units can also replace the traditional mid-range and tweeter units of a conventional, premium audio set-up. This significantly reduces overall component count doing away with associated crossover and wiring and thus reducing installation complexity, weight and overall system cost.

The first vehicles to include NXT AFR units are expected off the production line this summer. For further information about AFR go to the online version of the release at www.nxtsound.com
