Abstract
A balanced armature receiver is disclosed including a multicoil motor located in a housing and comprising a movable armature connected to a diaphragm separating an interior of the housing into front and back volumes. The multicoil motor is electrically connected to contacts of a terminal board having an integrated capacitor component, wherein electrical connections of the multicoil motor and the capacitor component to the terminal board are configured to change an electrical impedance of the balanced armature receiver based on a frequency of an electrical signal applied to the multicoil motor.
