Abstract:
A dual magnetic loop type receiver is composed of a yoke molding, a ferrite yoke, an annular magnet, a magnetic pole member, a vibration panel, a ferrite core, and a circular plate. While the receiver is operated, the annular magnet and the ferrite core and the ferrite yoke cause the receiver to produce an inner magnetic loop that interacts with the inner voice coil, and an outer magnetic loop that interacts with the outer voice coil such that the receiver generates vibration and sound.
