Core application areas

Smart earphones with full scene adaptation

TWS earphone magnetic suction system: Specializes in researching ultra-thin neodymium iron boron magnets (thickness ≤ 0.5mm), compatible with charging compartment opening and closing structures, magnetic suction error control within ± 3%, compatible with mainstream solutions such as Huawei and Apple.

Speaker magnetic circuit optimization: Customize N52/N54 high magnetic energy product magnets to enhance the sound pressure sensitivity of dynamic headphones and assist customers in obtaining Hi Res audio certification.

Anti drop design of sports headphones: Developed flexible rubber magnetic buckle, IPX7 waterproof and sweat resistant, suitable for neck hanging/ear hanging structures.

Innovative Applications in Consumer Electronics

Customized development of magnetic wireless charging modules (compatible with Qi standard), smart home magnetic control sensors, and other scenarios.

Competitive edge

Breakthrough of technical barriers:

Independently developed surface coating process (nickel copper nickel/epoxy resin), achieving 72 hours of salt spray testing without corrosion, solving the pain point of sweat erosion in TWS earphones.

Flexible intelligent manufacturing capability:

Supports precision machining with a tolerance of 0.05mm (wire cutting/multipole magnetization), and can undertake small-scale trial production (minimum order of 1000PCS), with sample delivery within 7 days.

Full chain quality control:

Through IATF 16949 system certification, the magnetic flux online detection system ensures batch consistency (CPK ≥ 1.67), and RoHS/REACH compliance guarantees worry free exports.

Customer Empowerment System

Joint development mode: Provide free magnetic circuit simulation reports to reduce customer trial and error costs.

Supply chain response: Dongguan local warehouse stocks standard magnets and delivers them quickly within 24 hours.

After sales guarantee: Components with excessive magnetic attenuation will be unconditionally returned to the factory for rework.

Cooperative customers: We have provided stable supply to three of the top 10 global TWS headphone manufacturers, with products applied to over 20 million sets of terminal devices.

Vision: To drive the ultimate experience innovation of intelligent wearable products through breakthroughs in magnetic micro precision.
