Updated: 2026-10-14 · Industry and engineering discussion, not evidence of supply to the following brands or every application.
01 / SMART AUDIO
Smart earphones: more functions, more specific structural requirements.
Apple's September 2026 AirPods 5 announcement emphasizes acoustic architecture, noise cancellation and hands-free interaction. Product developments encourage earlier discussion of circuit space, component dimensions and assembly conditions.
Project questions: sound generation or magnetic positioning? Is acceptance based on flux, surface field or field distribution? Added features do not necessarily mean more magnet material.

02 / SMART GLASSES
Smart eyewear: distinguish audio, imaging and display designs.
Meta's September 2026 announcement covers audio eyewear and an expanded product range, highlighting slimmer frames, audio and everyday wear.
Define the actual function, such as miniature speakers or magnetic positioning, before discussing magnetization, stray fields and environment. Conventional eyewear accessories are not equivalent to AI eyewear projects.

03 / ROBOTICS
Robot drives: start with rotor requirements.
Kollmorgen frameless motors comprise a wound stator and a separate permanent-magnet rotor. Compact drives make temperature, assembly profile and magnetic consistency important engineering considerations.
Evaluate robot-joint projects using magnetization drawings, thermal conditions, mechanical retention and validation methods. Equipment reference images do not establish production adoption in a particular joint.

04 / MAGNETIC ALIGNMENT
Magnetic alignment: connect components with system requirements.
WPC states that Qi2 25W launched in July 2025. Magnetic alignment remains relevant to the experience; arrays, polarity and assembly positions should be confirmed early.
Distinguish permanent-magnet alignment from wireless-power coils and soft magnetic structures. Similar component shapes do not establish certification or brand compatibility.

05 / MATERIALS
Reduced heavy rare earth and heavy-rare-earth-free are different approaches.
TDK describes NdFeB product routes with reduced heavy rare earths and without heavy rare earths. Heavy-rare-earth-free is not rare-earth-free, and substitution still requires validation.
Selection depends on circuit, temperature, demagnetization resistance and component conditions. Confirm material availability, properties and validation by project.

06 / SUPPLY CHAIN
Delivery planning also depends on the material supply chain.
The IEA's 2026 rare-earth report discusses supply concentration and risks from minerals to permanent magnets. Material availability, quotation validity and change communication all affect procurement planning.
Confirm specifications, quantities and milestones, then materials, samples and scheduling. Industry forecasts do not directly represent orders for any particular company.
