The rapid integration of advanced technologies in consumer audio products is changing the industry on a day-to-day basis. New features like Active Noise Cancelling, Hybrid Noise Cancelling, and voice-controlled smart systems are hardy considered premium options anymore, but simply what customers have come to expect. This directly impacts audio testing on production lines, where precise measurements to ensure sound quality are more vital than ever. This demand applies to mid- and low-end products, too, leading to increased production line costs and potentially strained relationships between contract manufacturers and audio brands. To successfully adapt to this trend, both electronics manufacturers and test microphone manufacturers need to embrace customized measuring products and solutions as the way forward. In GRAS Sound & Vibration, we have successfully adopted customization as a core principle driving product development and innovation.
Balancing Innovation, Quality, and Efficiency: A Dialogue Between Audio Brands and Contract Manufacturers
The world of audio product manufacturing is a dance between innovation, quality, and efficiency. This blog post explores the interplay between audio brands and contract manufacturers, revealing how their goals align and diverge in the quest for excellence.
Point: The Audio Brand Perspective
Audio brands are the visionaries, constantly pushing the envelope on quality and innovation. They face the challenge of maintaining their reputation for excellence while expanding their product lines. For them, the primary concern is ensuring that every product bearing their name meets stringent quality standards, which necessitates rigorous testing and compliance measures. The introduction of intelligent production line test microphones with EQset™ technology represents a solution to these challenges, enabling brands to achieve consistent, high-quality audio performance across their product range.
Counterpoint: The Contract Manufacturer's Standpoint
Over the years, many of our customization projects have turned into industry standards. By tailoring both technical specifications and form factor, as well as carefully considering where, how, and by whom the microphone will be used, we’ve succeeded in creating a number of bestsellers. Here are a few of our favorites.
At GRAS Sound & Vibration, we take great pride in our Operators.
They are the highly skilled men and women who handcraft, assemble, and test every GRAS microphone at our HQ in Holte, Denmark. They come from Denmark and around the world, and with various specialist backgrounds. Some have trained as watchmakers, others in pharmaceutical production. On top of that, each Operator undergoes rigorous training before joining our production, building on their unique skills to meet our exacting standards.
