PTT speaker/mike assembly
First Claim
1. A PTT transceiver which includes a microphone, a speaker, a PTT switch which can be manually switched from a receive mode to a transmit mode, and transceiver circuitry which broadcast radio waves representing sound detected by said microphone only when said PTT switch is in said transmit mode and which detects radio waves representing sound and delivers signals representing the sound to the speaker only when the PTT switch is in said receive mode, including:
- a mount assembly that mounts on a person'"'"'s head and that holds said speaker outside but adjacent to one of the person'"'"'s ear canals, and that holds said microphone outside but adjacent to the same ear canal and in the stream of sound that passes from the speaker to the person'"'"'s ear canal.

Abstract
A PTT transceiver (10) includes a mount assembly (16) comprising a shell (30) and a speaker/mike assembly (14) that includes a speaker (20) in the shell and a microphone (22) that lies in the same shell. The shell has a proximal end (66) with at least one opening (70) through which sound can pass out from the speaker and sound can pass to the microphone. An ear mount (32) holds the proximal end of the shell immediately outside an ear canal (C) of a person in an ear entrance region (80), it being found that sound from a person speaking can be detected near the outer end of the ear canal.

5. In a PTT transceiver that includes a speaker and that, when the transceiver is turned on it, remains on continuously except when a PTT switch is operated, the transceiver including a microphone that is on only while the PTT switch is being operated, the output of the microphone being amplified and transmitted to a remote station which has a remote speaker and remote microphone, the improvement comprising:
a mount assembly for holding said speaker and microphone at an ear of a person so a stream of sound can move from said speaker to the ear, with said microphone lying in said stream of sound so there would be a feedback loop if all speakers and microphones were on at the same time. - View Dependent Claims (6)

7. Apparatus for use by a person to pick up sound from the person when the person is speaking, comprising:
-
a microphone;
a mount which is mounted on the person and which holds said microphone immediately outside an ear of the person, in a sound pickup region that is of cylindrical shape with an axis and with a radius of 0.75 inch and with a length along said axis of 1.5 inches, said region extending along said axis from an outer end of the person'"'"'s ear canal and in a direction away from a side of the head of the person where said ear canal outer end is located. - View Dependent Claims (8, 9)

10. A method for generating sound representing received electrical signals from a remote location, to pass the sound to the ear of a person, and upon the giving of a command to transmit, picking up and transmitting to said remote location sound generated by the person during speaking and simultaneously terminating said generating of sound representing signals from the remote location, comprising:
-
placing a speaker that has a front, adjacent to the person'"'"'s ear, and energizing said speaker to generate said sound representing received electrical signals when said command to transmit is not being given;
placing a microphone adjacent to the person'"'"'s ear to detect sound thereat and transmitting signals representing said detected sound to said remote location during the giving of a command to transmit, where said microphone is positioned so it picks up sound from said speaker equal to at least −
3 dB of the level of sound one inch in front of said speaker. - View Dependent Claims (11)
