CX is a professional manufacturer of speaker components, and the only supplier with technical know-how and development on T-yokes, upper plates, U-yokes, and aluminum cones, CX products are widely recognized and used by world renowned speaker manufacturers in the world. Traditionally, the grooves inside the U-yoke are normally done by machining, leaving small steel debris adhere in the U-yoke, affecting the acoustics performance of the speaker. With further research on new tooling and enhance product quality in mind, CX successfully developed one-piece U-yoke, not just to reduce the machining process, but the savings on raw material and overall costs. With the growing concerns on protecting the environment, CX is contributing efforts to save the earth by implementing cyanide free alkaline plating process, substituting the hazardous hexavalent (Cr6+) to the safe-to-use trivalent (Cr3+) plating chemicals. In addition, CX products comply with RoHS (Restriction of Hazardous Substances), WEEE (Waste Electrical and Electronic Equipment) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations.

In addition, CX uses trivalent chromium chemical as well as non-cyanide anti-corrosion surface treatment processes in order to meet RoHS environmental requirement.


Precision drawing and forming of aluminum

Precision drawing and forming of aluminumPrecision drawing and forming of aluminumPrecision drawing and forming of aluminumUtilize compounded precision drawing and forming process on different thickness aluminum sheets (from 0.025mm to 0.5mm) to produce cones and membranes at various sizes


Anti-corrosion surface treatment on aluminum

Anti-corrosion surface treatment on aluminumCX can perform anti-corrosion surface treatment on oval and circular shaped aluminum cones, membranes, and dust caps with different colors and sizes (from 20mm to 250mm).

To strengthen new management styles and enhance technical capabilities, CX annually subcontracted training courses for 240 man-hour per month, including management related classes (TPS, 5S, problem analysis and solution, how to inspire employees, industry analysis, etc.), technical related classes (steel material selection and physical properties, forging and manufacturing technology of aluminum, heat treatment, surface treatment, etc.), and quality related classes (internal audit, APQP, MSA, PPAP, SPC, GD&T, etc.). CX will continue the efforts on improvement of production and technology via external trainings, and the on-job internal trainings to intensify technical abilities.

With ISO/TS16949:2002 quality system certification, CX products are more competitive and advantageous in the market. With more than 40 years involvement in the speaker industry, CX is one of the largest speaker components manufacturer in the world. Accumulating experiences and know-how, with numerous applications of speaker (information, communication, consumer electronics, automobile, etc.), we foresee there lies large room for growth in speaker industry, combining with CX’s know-how and technology, we can create more value by grasping the development trend.

Development Capabilities

CX extensively utilizes development capabilities from design, drafting, tooling, processing, equipment, and production management, applies them to all technical fields, i.e. cold forging, precision stamping, precision machining, anti-corrosion surface treatment on metal, precision drawing and forming of aluminum, and anti-corrosion surface treatment on aluminum.

CX strives for the research and development on new production method, new equipment, and new process management, with improvement and automation, in order to raise production efficiency, lower defective rate, and enhance overall competitive advantages. In addition, CX also aims for energy savings and low pollution green production processes.
