Wireless transmitting and receiving systems including ear microphones

A wireless transmitting and receiving system for use in two-way communication with a remote transmitter-receiver, comprising

• an ear microphone for picking up bone-conducted voice signals through an external auditory canal wall of one ear of a wearer thereof;
• a portable case having first mounting means for supporting said portable case adjacent the one ear of the wearer, and housing a first transmitter, a first receiver and a speaker;
• a wireless device having second mounting means for supporting said wireless device adjacent the wearer but spaced from said portable case and said ear microphone, and housing a second receiver and a second transmitter;
• said transmitters, receivers and speaker forming a communication loop including
• a first link with said first transmitter for transmitting output signals of said ear microphone to the remote transmitter-receiver;
• and
• a second link with said second receiver for receiving signals transmitted from the remote transmitter-receiver, said second transmitter for transmitting output signals of said second receiver, said first receiver for receiving signals transmitted from said second transmitter, and said speaker for acoustically converting output signals of said first receiver;
• whereby said first and second links provide a wireless connection between said portable case and said wireless device and permit wireless communication signals to be transmitted and received between the one ear of the wearer in which said ear microphone is mounted and the remote transmitter-receiver.

• a portable case having first mounting means for supporting said portable case adjacent the one ear of the wearer, and housing a first transmitter, a speaker and an induction coil;
• a wireless device having second mounting means for supporting said wireless device adjacent the wearer but spaced from said portable case and said ear microphone, housing a first receiver and having a loop antenna connected thereto and extending adjacent to said portable case;
• said transmitter, speaker, induction coil, receiver and antenna forming a communication loop including
• a first link with said first transmitter for transmitting output signals of said ear microphone to the remote transmitter-receiver;
• and
• a second link with said first receiver for receiving signals transmitted from the remote transmitter-receiver, said antenna for electromagnetically inducing output signals of said first receiver, said induction coil electromagnetically coupled to said loop antenna, and said speaker for acoustically converting output signals of said induction coil;
• whereby said first and second links provide a wireless connection between said portable case and said wireless device and permit communication signals to be transmitted and received between the one ear of the wearer in which said ear microphone is mounted and the remote transmitter-receiver.
