  • Electroacostic transducer
    Patent number: 5647013
    Abstract: This invention relates to electroacoustic transducers of the type which incorporate a reed armature. Thus a transducer 10 comprises a coil 12, magnets 13,14, pole pieces 15,16 and a reed armature 17, which passes through a central tunnel 18 defined the coil. A central portion 19 of the reed 17 lies within the tunnel and has opposed formation 20,21 which limit the possible deflection of the reed 17. Other deflection limiting arrangements are described.
