Electrical Audio Signal Processing Systems And Devices > Electro-acoustic Audio Transducer > Electromagnetic (e.g., Dyynamic) > Magnetic Circuit > Armature Diaphragm Armature DiaphragmArmature Diaphragm patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.11/08/07 - 20070258616 - Electroacoustic transducer with resistance to shock-waves A transducer comprising a pair of spaced magnets at least partially forming a tunnel having a central axis. A coil having a first and a second side wall and an upper and a lower wall at least partially forms the tunnel. A reed having a central portion extends through the ... 10/19/06 - 20060233418 - Loudspeaker with low-frequency oscillation A loudspeaker with low-frequency oscillation, comprising: a housing (21) with a ring portion (211) extending inwardly from the bottom thereof; and a reed element (22) having a top end attached to an oscillatable sound assembly, the reed element (22) further having an external ring (221) and two vibration arms (222) ... 09/28/06 - 20060215874 - Acoustic assembly for a transducer An acoustic assembly for use in a transducer includes a multi-layer structure. A first layer member includes a first center portion, a first edge portion and a first aperture separating the first center portion and the first edge portion. A second layer member includes a second center portion, a second ... 01/12/06 - 20060008110 - Receiver with multiple drive coils The invention provides a moving armature receiver, such as for a hearing aid, with at least two drive coils adapted to be driven by separate drive signal across different frequency ranges. This is achieved by a frequency dividing network adapted to split an audio input signal into first and second ... 07/14/05 - 20050152574 - Receiver having an improved bobbin A receiver is disclosed for use in listening devices, such as hearing aids. The receiver comprises an electromagnetic drive assembly that includes a bobbin having a coil of conductive wire formed thereon. The bobbin is capable of compensating for the deflections on the armature that may be caused by shock. ... ### FreshPatents.com Support |
