  • Patent number: 6563934
    Abstract: A diaphragm includes a vibratory membrane and at least one nickel titanium memory metal member having a shape that can be mechanically adjusted with a heating signal. The mechanical adjustment of the at least one nickel titanium memory metal member tunes the frequency response of the vibratory membrane in the diaphragm. The at least one nickel titanium memory metal member can be a sheet providing a vibratory membrane, or sheet sections or wire made of nickel titanium memory metal bonded to a vibratory membrane.

  • Patent number: 5288955
    Abstract: A wind noise and vibration noise reducing microphone arrangement is formed in a bullet-shaped housing (12) having a rounded front portion (13) and a flat rear portion (15). The rear portion is substantially perpendicular to the side portions (14) and contains a transducer (10) facing in the opposite direction from the forward portion. The transducer is mounted to the housing with an elastomeric member (25) that also serves as a seal between the transducer and the housing. The elastomeric member also reduces vibrations transmitted to the microphone. A mounting means (30) is attached to the housing. The mounting means has a vibration isolation member (32) to reduce vibrations transmitted to the housing. The mounting means can be an aerodynamic pedestal attached to the housing, with an elastomeric member attached to the pedestal to reduce vibrations.

  • Patent number: 5204907
    Abstract: An apparatus for mounting a noise cancelling microphone (34) within a communication device comprises a housing having a front portion (36), a back portion and side portions (40). The front portion (36) and one of the side portions (40) have apertures (38 and 40). Within the housing lies a receptacle (32 or 50 or 100) for retaining a microphone or transducer (34). The receptacle is arranged and constructed to form a chamber (32) between the apertures (38 and 40) in the front portion (36) and the side portion (40) of the housing.
