sides of the pseudo head Storage case of stereo microphone which is characterized by
Claims
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage case for
storing a stereomicrophone capable of pinaural sound collection, and in particular, it is proposed
to propose a case which can perform pinaural sound collection even in a state where the stereo
microphone is stored. is there. The storage case of the stereo microphone according to the
present invention has a pseudo head inside, and a sound collection through hole cover is
disposed opposite to at least both side portions of the pseudo head. There are two types of stereo
microphones to be stored in this storage case, one with and one without pseudo-auricle, and the
storage case for storing a stereo microphone without a pseudo-ear can be used for the pseudo
head. Provide a simulated pinna. In the following, first, some of the possible stereophonic
microphones for pinaural sound collection will be illustrated and then an embodiment of the
storage case according to the invention adapted to the structure of these stereo microphones will
be described. First, with reference to FIG. 1, the stereo microphone proposed earlier than the
present applicant will be described. In FIG. 1, M indicates a stereo microphone as a whole. (1), (1)

And, the windscreens (1) and (1) are attached to the metal annular frame (other plastic frame is
also acceptable) (2) and (21) in this example. The artificial pinna (4) and (4) are made of, for
example, plastic, and the shape close to the human ear and the sound V characteristic is desirable
EndPage: 1ε. The openings of the cup-like windscreens (1) and (1) are closed by the monitoring
through holes (12, (for example, a disc having a 121 and a disc made of plastic, a121, aυ, and
the disc αυ, 01) The artificial pinna (4), (4) are attached. (3) and (3) are a pair of microphone
units that allow non-directionality, and the shock absorbers (see Figure 1 and Figure 2) are
located on the artificial ear canal section of the artificial pinna (4) and (4). (Not shown) is
attached. (13, (13 is an annular ear cushion made of foamed plastic attached to the periphery of
the frame (2), (2). In addition, (51, (5) u are codes derived from the microphone unit (3), (3).

the other stereo microphone proposed by the present applicant will be described, but parts
corresponding to FIG. 1 will be described with the same reference numerals. In FIG. 2, M
indicates a stereo microphone as a whole. (1) and (1) are a pair of cup-like windscreens of a
shape and size that can accommodate the pinnacle, and in this example has a flat cylindrical
shape (others may be an elliptical cylindrical shape, a polygonal cylindrical shape, etc.) ing. A
windscreen of this type (IL (11 may be a wire mesh in this example (others may be a plastic net, a
plastic porous molded body, etc.)). The windscreens (1) and (1) are attached to metal annular
frames (other plastic frames are also acceptable) (2) and (2) in this example. (31, (3)) are a pair of
microphone units, which are mounted in the cup-like windscreen (1) so as to be positioned in the
ear canal artificial part of the pinna when worn respectively. In this example, the pair of
microphone units (3) and (3) is a frame +21 through the mounting brackets +4 and (4). It is
attached to f2 +. (5) is a code derived from the microphone units (3) and (3). (6) is a head
mounting tool, which is an elastic band (force, (7) such as metal or plastic, and blocks (8), (8)
such as metal or plastic attached to each end thereof; The blocks (8), (8) are comprised of metal
balls (9), (9) mounted so as to be embedded in the frames (2), (2) slidably mounted. The stereo
microphone M of the eyebrow is worn on a human head or a pseudo head having a pseudo ear (a
pseudo pinna). It can be worn and used. Another known stereo microphone will now be described
with reference to FIG. In FIG. 3, M indicates a stereo microphone as a whole. H and QS are a pair
of cylindrical microphone housings, each having a microphone unit (not shown) therein, and
(15a) and (15a) are sound collecting portions at the upper end thereof.

attached to the phase portion. A pair of elastic pipes 0 α and α 7) are attached to the housings
09 and α 9 at one end, and although not shown, the lead wire led out from the microphone unit
is housed inside thereof. And the other end of the pipe α 、, (I7) is attached to the block H, and

The stereo microphone M can be used by being fitted to a human ear or a simulated ear of a
simulated head. Next, an embodiment of the storage case according to the present invention will
be described with reference to FIG. FIG. 4 shows a storage case for storing the stereo microphone
M as shown in FIG. 1 described above. In FIG. 4, K indicates this storage case as a whole. The
storage case of the bag comprises a case body (2I), a lid (22), and a pseudo head (23) provided
on the case body. The case body CD and the lid (22 both have a rectangular parallelepiped shape,
and the lid (22 is attached to the case body (21) at the-side edge so as to be openable and
closable (# by screw number)). (Goods), (The second case is the case body (goods) and the lid
(The two are attached EndPage: 2 is a locking device. The pseudo class (c) is a generally
rectangular block as a whole having a cylindrical surface at the upper end as shown in FIG. In
this case, the pseudo-class (the width of 20 can be made approximately equal to the distance
between human's ears). Also, it is possible to make the pseudo-class (a) acoustically equal to the
human head. This pseudo class is provided at the center of the case body (21) so as to be in close
contact with the case body (21J front and back plates as shown in FIGS. 4 and 5). . In the case
body Qυ, both sides of the pseudo-class (c) are sound-collection through-hole covers 2, (2Q.
Since the covers (3) and (2Q are porous, and the stereo microphone housed in the storage case K
of this box has a wind screen, it is better that its hole is coarser than the wind screen. Although
not shown in the figure, the rear plate of the case body 01) is provided with a hole through which
the cord of the stereo microphone M passes. Storing the stereo microphone M of FIG. 1 in order
to store the stereo microphone M in the case K, the stereo microphone M is made to straddle the
pseudo class C 61 and the cord of the stereo microphone M is Expose the case body (21) to the
outside and close the lid (22).
Incidentally, as shown in FIG. 7, the artificial earlobe may be provided on both side surfaces
thereof with an ear cushion for the stereo microphone M of FIG. Also, as shown in FIG. 8, the
pseudo class (20 can be formed into a box, and the cord of the stereo microphone M or the like
can be stored therein. Father, as shown in FIG. 2, the storage case for accommodating a stereo
microphone without pseudo ears is made of pseudo ears (eg, soft plastic) on both sides of the
pseudo class (26) as shown in FIG. Allows you to make it resemble human auricle) (2al, (2a1
attached). Also, as shown in FIG. 10, the storage case for storing a stereo microphone as shown in
FIG. 3 is a pseudo-type (in this case, it has a shape resembling a human head) (20 Auricles) C) 8),
(2) and their pseudo ears (28, (2 mark pseudo outer ear canal (29), (I) are provided and the
projection 06 of the stereo microphone M), (+6) Make it fit. The column (G) is a support column,
and G1) is a base. In this base Gυ, this pseudo class (a) is fixed to the bottom plate of the case
body (2I). In the storage case, as shown in FIGS. 11 and 12, the entire aspect of the case body
(21) (except for the part of the locking device (24)) is a porous sound collecting through hole

cover (20 It is not necessary to make the pseudo class (c) contact the peripheral plate of the case
body e. The pseudo class in this case is also possible as shown in FIG. 7, FIG. 8, and FIG. When
the windscreen is not provided in the stereo microphone to be stored, it is desirable to make the
sound collection through hole cover a windscreen. According to the storage case of the stereo
microphone of the present invention described above, it is possible to perform pinaural sound
collection even in a state in which the stereo microphone is stored therein. (8)
