摘要： A method and apparatus for providing a hearing aid compatible wireless electronic device is disclosed. The apparatus may include a lower housing having a wireless transceiver, upper housing including an earpiece, hinge assembly, and a pair of reactive matching element along with predefined placement of the wireless transceiver. The reactive matching element can be implemented at different chassis inductances to achieve hearing aid compatibility within other design constraints. Implemented as a switched circuit or reactance filter circuit to create a reactance appropriate for a band of operation during transmission in that band.

摘要： An antenna is provided, which is located within an enclosure. The antenna includes one or more arms, where each arm has an electrical length corresponding to an intended frequency band of transmission, and along said length of the arm a source of external loading will have a variable effect. The enclosure includes one or more anticipated points of contact, where a source of external loading will be brought into proximity with said enclosure, and where the one or more arms are constructed and arranged to locate the relatively high impedance areas of the antenna at least a predetermined distance from the one or more anticipated points of interest, and the relatively low impedance areas of the antenna are located more proximate the anticipated points of interest.
