BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing the appearance of
an embodiment (7) of a microphone according to the present invention, and FIGS. 2 and 3 are
microphone elements which are used when the microphone according to the present invention is
used. It is a principal part sectional view showing the position of. 1: microphone, 2: through hole,
4: microphone case, 5: opening, T: diaphragm, 8: back pole, 11: microphone element, 13:
operation member.
The present invention relates to a micro 7 t n switchable directivity characteristic, and in
particular, a microphone which can be used by switching the directivity characteristic between
unidirectionality and non-directionality in the same microphone. It is about In a tape recorder ti
"> a simultaneous recording cine camera, a microphone used as an audio pickup member relates
to its directivity characteristic. Generally, those having unidirectional characteristics and those
having omnidirectional characteristics are offered to the market. When referring to these
microphones, for example, referring to a condenser microphone, the microphone element
consisting of the diaphragm and the back electrode (2) and the microphone element [the
microphone case to be stored can be used. Converted to and taken out. A microphone element
converts only the voice introduced from the microphone having the non-directional characteristic
described above or the opening provided forward of the microphone case into an electric signal
by the microphone element, while the microphone having the unidirectional characteristic. C.
Generally, apart from the opening provided on the wound surface of the micro 7 on case
described above, the opening for adding sound to the diaphragm of the microbalance element
from behind is formed on the micro 7 on case, A single directional characteristic is obtained by
adding voice to the & rigid plate of the microphone element from the both openings and
canceling common ones of voices added from the both openings to each other. On the other
hand, when recording voices with a tape recorder or the same lh recording cine camera,
according to the voices to be recorded, or (3) 1 in the recording / reproduction, the non-
directional characteristics described above as needed in consideration of the effect For example,
the microphone having one of the following characteristics is used. When picking up only the
target voice without surrounding noise, a microphone with a single directivity characteristic, and
when picking up conversations of several people with the same microphone, a wide
omnidirectional characteristic with a sound collection range Using a Micro 7 with a. 1) The tape
recorder L / 3 uses simultaneous recording cine camera! RF, each voice Each voice recording-In
order to perform appropriate voice pickup, it is not only necessary to always carry at least two
microphones with different inter-finger characteristics, but depending on each voice recording,
microphone replacement etc. It is forced to do complicated operation.
The first idea is to provide a microphone for eliminating the above-mentioned drawbacks, and it
is defined that a microphone element comprising a diaphragm and a back electrode is introduced
into the diaphragm of the microphone element by voice from solution. A through hole and the
through hole a. (4) A microphone is housed in a microphone and has an opening formed in the
shoulder surface so as to be slidable. In order to transfer # 1 of the micro 7 t element between
the three positions in the microphone couss, it comprises an operation member disposed on the
microphone nurse and is in one position in the micro 7 on case or the microphone element The
sound from the through hole of the microphone nurse from the front side of the diaphragm of
the microphone element from the front, 111 &! By adding the voice from the opening of the field
of the microphone field 7 on the rear from the rear side, the microphone is given a single
directivity characteristic, and when the quadruple microphone element is at the other position in
the microphone couss, The directivity characteristics can be switched by giving a non-directional
characteristic to the microphone by adding from the front side the sound from the through hole
portion and the opening portion of the microphone nurse to the lift side plate of the at
microphone element The An embodiment of the microphone of the first proposal will be
described in detail with the plane (5) shown in the following. In Figs. 1 to 3 (2), the front surface
Krr of the microphone l, the front plate 3 having a plurality of passage holes 2 for passing the
sound% I, or the microphone case 4 is attached. The microphone case 4 is formed with a plurality
of open I: J portions 5 along the surface, and a slot 6 is formed in the longitudinal direction. In
particular, in FIG. 2 and FIG. 3, in the microphone case 4, the diaphragm 71 back & 8 and the
insulator 9 are housed in the microphone element 11 which is unitized and held by the holding
body lO. WfJ [le microphone element U is formed on the surface of the holder lO of the rs
microchip Ik 7 on main body 40 and is formed with a plurality of uniform openings F1612 and
integrally with the holder IO in 1 history Is the operation member register formed, I! It projects
from the slot 6 of the microphone case 4 of iI. The microphone element U is operated to move
the operating member 13 along the slot 6 in the longitudinal direction of the microphone 1 in
the longitudinal direction of the microphone 1, and is movable (6) 11 in the micro 7t sensor 4
and substantially 2 It is stored to move between positions.
The microphone attached to the rear of the microphone case 4 is housed in the housing 14 in the
amplifier 14 connected to the back pole 8 of the microphone element 11, and the back pole 8
and the amplifier positive and ground microphones In the case 4 and the amplifier positive
amount, for example, a flexible turtle jc which has enough margin so that the connection state
does not change even if the microphone element 11 moves. It is connected by a connecting line
16. The microphone of the present invention comprises one or more configurations and its use
will now be described. When used as the microphone lt of the present invention as a
unidirectional microphone, the operation member 13 is moved to the forward position wJ as
shown in FIGS. As a result, the microphone element 11 integral with the operation member U
reaches the position shown in FIG. 2, and in this state, the opening 5 of the rr1 micro 7 on nurse
4 and the opening a12 of the microphone element 11 coincide with each other. (7) The voice rX
entering from the opening 5 is added from the rear of the diaphragm 7 of the microphone
element 11. For this reason, the voice entering from the passage hole 2 of the surface 611 of the
microphone 1 enters from the opening 5 The speech components common to speech cancel each
other out and substantially only the narrow range 0 speech in front of the microphone l will be
picked up. On the other hand, when the microphone riff-on 1 is used as a nondirectional
microphone, as shown in FIG. 3, the operation member L3 is slid backward along the slot 6. As a
result, as shown in FIG. 3, the microphone element 11 is positioned behind the opening 5L of the
microphone riff-on cous 4 and the sound from the opening g5 is transmitted to the microphone
element 11 together with the sound from the surface of the microphone l. At this time, sound can
be collected over a wide range of the microphone 1rX and can be used as a nondirectional
microphone riff-on. As described above, in the microphone solution (8) 1; of the first proposal, it
becomes possible to easily switch the directivity with one microphone, and when recording with
a tape recorder or a simultaneous recording cine camera, the microphone is selected according to
the recording voice. There is no need to change, and it is extremely convenient in practice. In one
embodiment of the present invention, the operation member is moved and the microphone
element is shown to be # 1111I, or another method if it is a structure to move substantially
between the microphone element and the second position. Of course, you may use.
Also, although not shown in the embodiment of the first proposal, it is particularly advantageous
to ensure the directional switching operation by providing a known locking means for locking the
microphone element in two positions.
