Stetron Stories: How we can help you

Stetron’s team of audio engineers has worked with clients across a variety of industries to assist in audio component design, test and data evaluation, loudspeaker enclosure design and so much more.

Our  audio engineers work with our clients to fully  understand their project requirements and to define the most cost-effective way to achieve their desired audio results.

Whatever your project requires, Stetron has the Audio Solution.

A Speaker Box Solution

Situation: A company who creates lifestyle products for residential and commercial use was looking for audio assistance on a new product for the home automation industry.

Problem: The company was creating a new home automation product that required a speaker box solution. The product needed to exude loudness and fidelity while working in a compact footprint. Due to varying speaker box enclosure sizes, the company was unsure of which speaker box solution would work best for their product.

Solution: Stetron was able to create rapid prototypes using 3D printing to create multiple speaker box solutions. Using varying types of speakers in each speaker box, Stetron was able to test various components and solutions based on real samples. Stetron was able to offer a complete acoustic component recommendation based on the key features the company was looking for. Stetron conducted full acoustic tests using CLIO and SoundCheck software to determine the speaker performance. Using software simulation, Stetron audio engineers were able to determine enclosure back volume and theoretical response of the system. Stetron ultimately determined which speaker should be used along with a properly sized enclosure box to provide the customer with the best sound quality for their product.

Outcome: Stetron was able to effectively demonstrate, during a live demo, that the speaker will perform best if the enclosure was properly sized. The client was able to change their design philosophy to incorporate our recommendations.

A Speaker Enclosure for a Loudspeaker

Situation: A company dedicated to smart home applications was working on a new-to-market product that would help their customers enjoy their homes via increased comfort and energy savings.

Problem: The new-to-market product they were creating was still in 3D model stage and the company needed to create actual product samples to provide a demonstration to their investors. The end product needed to exude loudness and fidelity.

Solution: Stetron evaluated the customers 3D models and identified a 50mm loudspeaker driver inside of a speaker enclosure as an acoustical recommendation to the company. Utilizing Solidworks 3D modeling of enclosures, Stetron created a customized speaker box and fit it with our driver and then completed a complete acoustical testing analysis. Using software simulation, Stetron audio engineers were able to determine enclosure back volume and theoretical response of the system. Both the CLIO and Soundcheck test and measurement software were used to determine product performance.

Outcome: Stetron was able to provide a detailed report to the client on the acoustical features as well as an actual product sample the company was able to use to demonstrate the product to their investors.

A Product Evaluation and Component Recommendation

Situation: A company who makes products to monitor sleeping patterns was interested in adding audio to their products.

Problem: Being unfamiliar with audio, the company was unsure of the type and size of speakers that were needed as well whether an enclosure would be needed. The company knew their end product needed to focus on clarity and loudness while keeping true to their product footprint.

Solution: Stetron was able to quickly evaluate the new product and make several acoustical component recommendations. The Stetron audio engineering team suggested a 28mm speaker and a 40mm speaker. To accommodate the product enclosure, Stetron created two project box mockups, generated detailed acoustical reports on each speaker and offered the client a precise idea of which speaker would work best in their end product to provide the clarity and loudness the client was looking for.

Outcome: The company utilized Stetron findings to move forward in their project.

Testing and Evaluating Microphones

Situation: A company who manufactures headsets and other types of consumer electronics and for the gaming industry were developing a new product.

Problem: This client had a two-part problem. The first was they needed a suitable electret condenser microphone for a new headset they were developing. The second, they needed independent testing on a microphone they were using in an existing product.

Solution: The Stetron audio engineering team provided a comprehensive audio component evaluation and made suggestions on which Stetron electret condenser microphone would be a suitable fit for the headset. Additionally, Stetron conducted an evaluation of the customers’ existing component using HATS, performed testing and supplied suggestions on how to enhance the performance of the existing components.

Outcome: The company was appreciative of Stetron's technical knowledge and suggestions.

Testing and Evaluating Speakers for a New Product

Situation: An existing customer was developing a new product for the telematics industry.

Problem: While developing the new product, the company required several rounds of testing during manufacturing and upon product completion.

Solution: Stetron assisted the customer by first conducting extensive testing to determine how the company selected speaker and microphone would behave in an enclosure. Stetron audio engineers used HATS to conduct microphone evaluations as well as CLIO and SoundCheck to determine performance. Using software simulation, Stetron audio engineers were able to determine enclosure back volume and theoretical response of the system. After production, Stetron again tested the finished product to determine the frequency response of the loudspeaker and compare it with other existing products.

Outcome: Using our recommendations, the customer implemented our findings to improve the application.

Testing and Evaluating Speakers and Enclosures

Situation: A premier manufacturing company which makes innovative respiratory and personal protective equipment for firefighters, police officers and security and rescue teams worldwide.

Problem: The company was in the design phase of a new product and they needed to complete testing on a loudspeaker and determine which configuration of their product would yield the most favorable acoustic results. The company wanted to measure loudness, fidelity and power handling.

Solution: Stetron audio engineers brought the customers product into the lab to accurately measure and test the loudspeaker to be used. Stetron audio engineers assembled various configurations of speakers and enclosures to perform full acoustic testing. Using software simulation, Stetron audio engineers were able to determine enclosure back volume and theoretical response of the system. Both the CLIO and Soundcheck test and measurement software was used to determine product performance.

Outcome: During the acoustic tests, several assembly issues were discovered that if corrected would render enhanced acoustic performance. Stetron audio engineers then corrected the assembly issues and conducted further testing. Additionally, the audio engineers were able to suggest an alternative loudspeaker solution that met the customer's goals but also improved the low-frequency response.

Improving Power Consumption on a Loudspeaker

Situation: A premier manufacturing company who makes fire and safety products was looking to improve their product power consumption while gaining an advantage in market competition.

Problem: The final product needed to maintain its loudness and could not be affected in the situation of a lower power consumption.

Solution: Stetron  audio engineers obtained the drive board from the customer and completed a power consumption measurement based on the real application conditions. It was determined that in order to achieve and maintain the required loudness of the product the loudspeaker driver was demanding too much power from the amplifier. Based on our test results, Stetron audio engineers were able to deduce what the necessary electrical performance was that the loudspeaker needed to meet, in order to match the drive board capability and achieve the expected power consumption level. Our audio engineers were then able to use this information as prerequisites for a new speaker design while maintaining the same target loudness as the original speaker.

Outcome: Stetron was able to provide a new speaker solution to the customer that helped to achieve a 50% power savings without sacrificing acoustic performance.
