摘要： A balanced armature receiver includes a gas permeable barrier located on a portion of the receiver defining a back volume to provide barometric relief. The barrier can be located in a wall portion or diaphragm of the receiver to vent the back volume to an exterior of the receiver directly, via a front volume, or via a nozzle. The gas permeable barrier is impermeable to liquid infiltration and can be configured to influence the low frequency response of the receiver.

摘要： A balanced armature (BA) receiver and specifically a nickel-iron (Ni—Fe) alloy armature having improved robustness and performance receivers, as well as motors and receivers including such armatures are disclosed. The Ni—Fe armature has a nickel content of 45% or less by weight, 5% or less additive and impurities by weight, and the balance Fe. The armature can be configured as a U-reed, an E-reed or in some other configuration.
