  • Microphone having a microphone capsule, dynamic sound transducer for headphones, earphones or headsets and method for producing a microphone capsule or a sound transducer
    Patent number: 9661419
    Abstract: A microphone having a microphone capsule is provided. The microphone capsule has a diaphragm carrier, a diaphragm and an adhesive tape ring which is used to fasten the diaphragm to or in the diaphragm carrier. The microphone capsule is in the form of a dynamic sound transducer. A dynamic sound transducer for headphones, earphones or headsets is also provided. The sound transducer has a diaphragm carrier, a diaphragm and a moving coil which is coupled to the diaphragm. In a similar manner to the microphone capsule, the sound transducer has an adhesive tape ring between the diaphragm and the diaphragm carrier, which ring is used to fasten the diaphragm to the diaphragm carrier.

  • Dynamic electro-acoustic transducer and earphone
    Patent number: 8180097
    Abstract: There is thus provided a dynamic electro-acoustic transducer having a moving coil (100) with a coil exit location (110) and a first and a second feed line (200, 300). The first and second feed lines (200, 300) have first ends (210, 310) for coupling to the coil exit location (110), an intermediate portion (250, 350) and second ends (220, 320). The intermediate portions (250, 350) of the first and second feed lines (200, 300) are substantially parallel to a tangent at the moving coil (100).
