True Technologies has a long history (20 years+) of doing design work for products that make sound. We have done transducer designs from 1/2" earphone drivers to 24" 1000W subwoofers for speaker companies in automotive, consumer electronics, pro-sound markets. We have also done systems work with projects in automotive sound systems, headphones, high end home audio speakers, etc. One of our niches is catering to companies that need to incorporate sound into their products but don't have the internal expertise. These customers have come from the medical, railroad, safety device, marine, and gaming industries.
Give us a spec and a cost target and we can support your team from concept to post production support, or however you need us to fit in. We have connections for component suppliers and manufacturers all over the world.
