发明名称 SPEAKER VOICE COIL ANTENNA
摘要 <p>A wireless communication device (50) can include a radio frequency transceiver (52), an audio drive circuit (58) coupled to the transceiver, a speaker (10) having a voice coil (16) coupled to the audio drive circuit, and an antenna feed or radiating circuit (20) such as an RFID or NFID circuit coupled to the voice coil for at least radiating or receiving an electromagnetic signal via the voice coil. Such radiating circuits can be coupled to the voice coil using a band pass circuit designed to substantially prevent a radiating signal from the radiating circuit from interfering with audio drive circuit driving the speaker. The wireless communication device can further include an antenna (54) coupled to the radio frequency transceiver. Note, this arrangement can be designed to avoid problems involving electrostatic discharge sensitivity, electromagnetic interference coupling between the antenna and the voice coil, total radiated power, and specific absorption rate.</p>
