| 摘要 |
An electromagnetic transducer for generating vibrations for sounds and/or words bone conduction, comprising a magnetic yoke comprising a ferromagnetic material base plate (2), a magnetic pole (3), a voice coil (4) positioned around the magnetic pole (3), a pair of permanent magnets (5) positioned outside said voice coil (4) and a vibrating diaphragm (6) of ferromagnetic material supported by said non-ferromagnetic support means (7). Advantageously, such support means (7) are supported by said base plate (2) by means of fastening brackets (8) that engage portions of said support means (7) projecting beyond said base plate (2), exceeding opposite ends of the base plate (2). |
