Application of Laser Welding Machines in Mobile Phone Motors

We all know that phones have a vibration function, but who knows how phones achieve vibration? It's actually because phones contain a small motor. How is that motor placed inside the phone? Today, Top Opitcs Laser Welding Machine Manufacturer will introduce the application of laser welding machines in phone motors.

Motor: Refers to an electric motor or engine. Its working principle involves electromagnetic induction driving the starter motor's rotor to rotate. The pinion gear on the rotor then drives the engine flywheel to spin. The miniature vibration motors primarily used in phones belong to the category of DC brushed motors. The motor shaft features an eccentric wheel. When the motor rotates, the center point of the eccentric wheel is not aligned with the motor's rotational center, causing the motor to be in a constant state of imbalance. This imbalance, due to inertia, generates vibration.

With technological advancement, LRA linear motors have emerged. Structurally distinct from ERM motors, these devices achieve linear motion-based vibration. Essentially, a linear motor unfolds the rotational motion of a conventional motor along its axis, converting it into linear movement—hence the name. Linear vibration motors enhance device notification systems by delivering amplified sound alerts, offering users an enriched sensory experience. Impressively, through contextual vibration feedback, these motors provide nuanced and subtle interactions—such as taps or heartbeat sensations—during use.

So how does such a powerful motor connect with other components inside a smartphone? Precisely—it's all thanks to laser welding machines!

Laser welding represents an innovative welding technique capable of producing weld seams exceeding the strength of the base materials. Metal motor laser welding machines operate with minimal consumables, significantly reducing downtime and auxiliary processing time while delivering high production efficiency. Furthermore, due to the extremely small focused spot size, weld seams can be positioned with high precision. The beam's ease of transmission and control enables welding at long distances, in hard-to-reach areas, and on micro-components.
