Japan. (1976) 5.7732655 Description: A microphone according to the invention, wherein a
projection for insertion of the external auditory canal is attached to a through-hole capsule for
microphone collection, and a microphone unit is housed in the capsule.
DETAILED DESCRIPTION OF THE INVENTION The present invention proposes a microphone
microphone that can be used for pinaural sound collection, which is simple in structure and can
be easily worn on the ear. The invention will now be described in detail with reference to FIG. 1
according to an embodiment of the invention. In FIG. 1, 11) is a sound collection through hole
capsule, which is the whole town as a wind screen. (2) is the large number of through holes. (3) is
a protrusion for inserting the ear canal. A monitoring through hole (4) communicates with the
inside of the capsule +11. And the projection (3) and the capsule (1) are integrally formed by
plastic molding. (5) is a microphone unit which is housed in a capsule (1) [the ommitance
attached to the town is 1 "with the town. (6) is a code derived from the microphone unit Fl) to the
outside of the dicapsule fi +. The same microphone M is used simultaneously as a pair. In use, the
projection 13) is inserted into the ear canal n, and the microphone unit (5) picks up the sound
that has intruded into the capsule (1) from the outside, but this sound simultaneously ) Through
the through hole (4). In addition, as shown in FIG. 2, use a clip (7). Attach-and -n to the cap (may
be an eye-casting temple) (8), and stop the cord (61 ヲ this clip (7) through) the contact noise of
the cord + 61 is picked up by the microphone M There is less concern. If the microphone
according to the present invention to be described above has a protrusion for inserting the
external ear canal attached to the sound collection through hole capsule and the microphone unit
is housed in the capsule, the structure is simple and the ear is easy Although it is a human ear, it
may be worn on a pseudo head ear) and used. Also, when using a windscreen as a multi-capsule
capsule for sound collection EndPage: 1, this can effectively prevent the microphone unit from
picking up wind noise. The sound collection through hole capsule described above may be
partially or entirely made of wire mesh or plastic mesh. In addition, the through hole (4) may not
necessarily be provided in the ear canal insertion projection 13).
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view showing an embodiment
of the present invention, and FIG. 2 is a perspective view showing a mounting state of another
embodiment of the present invention. 111 is a sound collection through hole capsule, (3) is a
protrusion for inserting the external ear canal, and (5) a microphone. Patent applicant Sony
