SPEAKER WITH COIL ANTENNA

摘要

A speaker is provided in which both audio signals and radio frequency (RF) signals are simultaneously fed to the coil of a speaker device causing the coil to drive the speaker's membrane producing sound and operate as an antenna for various electromagnetic frequencies. The speaker can be equipped with appropriate filter circuits to isolate the audio signals and RF signals within the speaker device.

主权项

1. A speaker device comprising:
a yoke; a magnet disposed within the yoke; a top plate disposed on one side of the magnet; a coil surrounding the magnet, the coil configured for movement in a space between the yoke and the magnet; a membrane connected to the coil; a plurality of coil leads connected to the coil; an audio circuit connected to the coil through the coil leads; and a radio frequency (RF) circuit connected to the coil through the coil leads, wherein the audio circuit generates audio signals that are delivered to the coil for the production of sound and the RF circuit generates RF signals that are delivered to the coil for the production of electromagnetic signals, the audio signals and RF signals being delivered to the coil simultaneously.
