Jewelry micromotors typically refer to miniature vibration motors used in smart wearable devices for jewelry (such as smart rings and smart bracelets) to provide haptic feedback, message notifications, and other functions. These motors have extremely high requirements for size, weight, and appearance, needing to be compatible with the jewelry materials and maintain aesthetic appeal.
Depending on application requirements, the core materials mainly include:
Motor Body: Utilizing a permanent magnet hollow DC motor structure, featuring small size (3.2–12mm diameter), low power consumption, and low noise, suitable for embedding within jewelry.
Shell Material: To match the high-end attributes of jewelry, the shell is often made of stainless steel or aluminum alloy, balancing lightweight and corrosion resistance; some high-end products use nickel plating or blackening treatment to enhance texture and wear resistance.
Integrated technology: In products such as the Dreame AI smart ring, the motor is precisely encapsulated in a precious metal body such as 18K gold and platinum (Pt950). Through miniaturization design, the electronic components are completely hidden, realizing the fusion of technology and jewelry aesthetics.
