Title:
VOICE-INPUTTING EAR MICROPHONE
Document Type and Number:
WIPO Patent Application WO/2007/099893
Kind Code:
A1
Abstract:
Provided is a voice-inputting ear microphone, which can be removably fitted in
an ear to perform bilateral communications with an outside transceiver. The microphone
(10) is enveloped by an elastomer (11) arranged in the inner face of a body (5) on
an opening side to close an opening (3), and sound collecting holes (13, 19) of
equal diameter and number are formed in the front facing the opening and in the
back on the opposite side of the opening. The front sound collecting holes (13)
are made to communicate with the opening (3) by sound collecting paths (14, 15,
16) formed in the elastomer, so that they can collect the external auditory canal
voices from the opening side. The back sound collecting holes (19) are so directed
toward closed spaces (18, 21), which are formed of a sound absorber (20) arranged
in the inner face of the body on the opposite side of the opening and the elastomer,
as can collect the voices from the sound paths (16, 17), which are branched from
the opening or the sound collecting paths and formed to communicate with the closed
spaces.
