ABSTRACT:
A portable system for recording telephone conversations from a telephone and also for recording face-to-face conversations includes a portable, battery-powered audible sound recorder carried by the user, a microphone connected to the recorder, and a microphone support which is supported by the ear of the user for retaining the microphone between the telephone earpiece and the inner portion of the auditory meatus of the user. By locating the microphone near the auditory meatus or in the outer portion of the auditory meatus of the user, sounds of the face-to-face conversation and sounds of the telephone conversation from the earpiece are recorded on the recorder. With the recording system of the invention, there is no physical contact between the microphone and the telephone earpiece. A microphone holder is also disclosed for retaining a small microphone near or in the auditory meatus of the user. By using the microphone holder, any conventional portable audio recorder in conjunction the small microphone can be converted into a portable telephone conversation recording system or portable face-to-face conversation recording system. A combined microphone/speaker can be used for both recording sounds and for playing back the recorded sounds.
