Скачать или смотреть How a Mini SPEAKER Driver Is Built 🎵

In a speaker assembly workshop, a worker prepares a 3-inch driver using a semi-automatic gluing system. The glue nozzle drops down and applies adhesive in a clean, rotating pattern, while the worker handles the precision step — placing the dust cap perfectly on top. With human accuracy and machine consistency working together, the small speaker is nearly ready to leave the line.
A 3-inch speaker is built by aligning the magnet and voice coil, bonding the diaphragm, and using a centering spider to control vibration. The round cap on top is the dust cap, which acts like a protective shield for the magnetic gap. It blocks dust that could cause distortion and also shapes the driver’s high-frequency response. This lightweight structure improves cooling and keeps the coil stable during fast movement, allowing even small speakers to produce clean, clear midrange sound.
