Combined in-ear speaker and microphone for radio communication

摘要

A multivoice radio system allows users to speak and listen, at the same time, to others using multivoice radios without using a base station. Several embodiments of the present invention are directed toward combining a multivoice radio with push-to-talk (PTT), long-range radio. Other embodiments combine two or more multivoice systems and/or use an extender to increase a distance that multivoice radios can communicate with each other. Combining multivoice systems, in some embodiments, creates a voice and/or data mesh network. Switch-to-talk (STT) functionality can be added to systems to increase a number of users and promote radio discipline. Additionally, a combined in-ear microphone and speaker is disclosed. Further embodiments are directed to combining duplex radios, such as mobile phones, to multivoice systems, and/or PTT systems.

主权项

1. An audio device for a combined in-ear speaker and microphone, the audio device comprising:
a speaker input configured to:
receive a first electrical signal, wherein the first electrical signal represents an audio communication; andtransmit the first electrical signal to a filter; the filter configured to:
receive the first electrical signal;receive feedback from an electrical signal that has passed through an additive mixer; andtransmit a second electrical signal; a speaker output configured to:
receive the second electrical signal, wherein:
the second electrical signal is a modified version of the first electrical signal; andthe second electrical signal represents the audio communication; andtransmit the second electrical signal to a speaker; the speaker, wherein:
the speaker is configured for insertion into an ear of a person;the speaker is configured to transduce the second electrical signal into compressed airwaves; andthe compressed airwaves are transmitted directly into an ear canal of the ear of the person, whereby the person hears a sound; a microphone, wherein:
the microphone is configured for insertion into the ear of the person; andthe microphone is configured to transduce compressed airwaves received from in the ear canal into a third electrical signal; a microphone input configured to receive the third electrical signal from the microphone; a phase adjuster configured to:
receive the second electrical signal;receive a fourth electrical signal, wherein the fourth electrical signal is received from the filter;receive feedback from the electrical signal that has passed through the additive mixer; andmodify the second electrical signal to produce a fifth electrical signal, wherein modifying the second electrical signal to produce the fifth electrical signal:
uses the fourth electrical signal and feedback from the electrical signal that has passed through the additive mixer; andmodifies a phase of the second electrical signal; and the additive mixer configured to:
receive the fifth electrical signal from the phase adjuster;receive the third electrical signal from the microphone input;add the fifth electrical signal to the third electrical signal to create a sixth electrical signal, wherein the audio communication is suppressed in the sixth electrical signal; andtransmit the sixth electrical signal to a microphone output.
