Micro-Speaker

摘要

A micro-speaker is disclosed. The micro-speaker includes a frame, a magnetic circuit unit in the frame, a first vibration unit, and a second vibration unit. The magnetic circuit unit forms a first volume cooperatively with the first vibration unit, and a second volume cooperatively with the second vibration unit. The magnetic circuit unit further includes an aperture for communicating the first volume with the second volume for enabling the first vibration unit in phase with the second vibration unit.
