Title:
FLAT AND MOVING-COIL COMBINED-TYPE VIBRATING DIAPHRAGM ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2017/088712
Kind Code:
A1
Abstract:
A flat and moving-coil combined-type vibrating diaphragm assembly, comprising a vibrating diaphragm (5), a first wire coil (6) arranged in a circular shape on the vibrating diaphragm (5), the vibrating diaphragm (5) being fixed with a second wire coil (7), the center of a circle formed by the second wire coil (7) being concentric with a circular ring formed by the first wire coil (6), at the same time, a corresponding moving coil magnet (4) being provided at a corresponding location, the first wire coil (6) consisting of at least two sets of circular wires, each set of the circular wires consisting of multi-turn wires, two adjacent sets of the circular wires being spaced at a certain distance to form a circular gap, in which a corresponding annular magnet (3) is provided, the polarity direction of the annular magnet (3) being perpendicular to the circular plane on which the annular magnet (3) is located, the polarity directions of adjacent annular magnets (3) being opposite, and the annular magnets (3) being provided on same side of the vibrating diaphragm (5) or provided correspondingly on both sides thereof. The flat and moving-coil combined-type vibrating diaphragm assembly combines the traditional plane vibration mode and moving coil vibration mode, and makes the two work collaboratively, such that the force received by the vibrating diaphragm being more uniform, suppressing the split vibration, providing a better sound quality.
