An electro-acoustic micro-converter can be applied in an audio device, and in particular in a hearing aid. The micro-converter is at least substantially block-shaped and includes an at least substantially rectangular acoustic membrane tensioned therein transversely of a longitudinal direction. A coil element is carried by the membrane and extends in a magnetic field maintained by magnet elements, including a permanently magnetic magnet body, in a coil gap around the magnet body. |
