Product Advantages
Specialized & Diversified Solutions for Audio Needs
Over 30,000 speaker sizes and series are available for selection, covering extensive application scenarios.
Complete audio intelligent integration system
A complete audio product relies on a set of discrete components. Speakers depend on audio PCBA for tuning and on housing structures to optimize volume and sound quality.
PCBA manufacturers focus solely on electronic products, speaker manufacturers specialize in acoustic components, and housing manufacturers only optimize plastic casings. This fragmented manufacturing model creates critical gaps in the final product.
When these components are designed without coordination, integration issues inevitably emerge in the later production stages — misalignments during assembly result in inconsistent acoustic structures, undermining sound performance.
Zehsm Audio was founded to eliminate these gaps. By integrating these three core capabilities under one roof, we optimize the entire audio system rather than just individual components. We identify integration issues at the design stage, not during production, and take full accountability for the final product’s quality and performance.
