DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microphone for
a miniature toroidal projector and, more particularly, to a microphone provided with an input
adjusting device suitable for after-recording (1) recording by one person. This is a home-use
toque-projector, and after-recording is performed to record music and commentary suitable for
the scene while projecting the current Ailum. However, generally speaking, good recordings have
not been obtained. The lack of a complete recording facility like a divine film, that the user is not
mature in sound recording technology KW, and if he has to carry out various operations by one
person, it can be cited as a cause . A home-use toque projector has a built-in recording and
playback device, and the projector is provided with a microphone input terminal (microphone
input jack) and an auxiliary input terminal (AUX input caulker jack). Now consider the case
where you want to comment (narration) at an appropriate rx place on the screen while feeding
appropriate music from a tape or record player with AUX input. Because the film transport
mechanism produces noise during projector operation, it is safe to put the microphone as far
away from the projector as possible. (2) The recording circuit of a normal projector is provided
with automatic volume control (A, G, C) circuits, and when there is little recording input, the
amplification degree is automatically increased, and the recording level is averaged VC is going
to be Because this automatic sound tiI 1 node circuit is closed, if the microphone is brought close
to the projector without the voice pressure being applied, the noise of the projector will be
recorded and the VC will become VC. Easy to start when recording with VC1 alone. This is
because if the projector is in close proximity to the projector for the operation of the projector or
the attachment / detachment of the microphone terminal. For this reason, the inventor of the
present invention, microphone output electron in the microphone body! We have proposed an 8
mm toroidal cinematic microphone that can be Ilj #. That is, the microphone, the voice, the left 'in
the output circuit, the output' jr is gradually reduced and corrected. And the operation knobs of
the seven circuit devices are disposed on the main body of the microphone. According to this
microphone, the noise of the projector described above can be reduced. The microphone
according to the present invention is a friend to further improve the (3) microphone described
above, and the object of the present invention is to switch or combine the inputs only by the
operation in the microphone body when recording two or more inputs. It is to provide a
microphone that can be
In order to achieve the above object, the microphone according to the present invention is
provided with a pair of attenuation devices in the microphone mallet. And one of the damping! !
The input terminal of the snow is connected to the output of the sound-to-electricity conversion
cell, and the other input terminal of the attenuation device is connected to another sound signal
source. The respective damping devices #i are configured to be controlled by one operation
member so that the damping factors thereof change in opposite directions. In this process, the
microphone output can be rationally recorded by switching or combining the microphone output
and signals from other signal sources. Damping of one attenuator! If the correspondence
between 1001 and the attenuation of the other attenuator [04] is made compatible, excellent
unique effects such as being able to be used as input switching device 111 as an input switching
device (4) can be obtained. The following is a more detailed description of the present invention
with reference to the example bone and the like. FIG. 1 illustrates the relationship between the
microphone 1 according to the present invention, another audio signal source, and the input
circuit of the recording device of the projector. FIG. The microphone IK is provided with a voltage
divider す る for the output voltage 'J'e + f of the sound pressure-electricity conversion cell, and
other voice power supply electrons, for example, a molecular gain bird that divides the tape
recorder output and the record-player output. There is. One end to the divider is connected in
common, and the cffiK contact of the microphone plug P1 is performed. Resistors R, R are
connected to the lead points of the voltage dividers R, R, respectively. The other ends of these
resistors R,, () are connected to a common VC connected plug P at three points J [. Projection * &
C built-in recording and playback (b) Jack J1. Processing J is provided. プラグP。 Is connected
to jack J, the three points of flag P are connected to terminal f of jack J1 to be coupled to the
input = (5) terminal of amplifier A, point b to h terminal, cA to 1 terminal It is grounded. Another
audio power supply is coupled to the jack J of the recording device l via the plug P. The terminal
e is connected to 1 at the terminal j of the terminal P of the plug P, and the terminal J is
grounded. As a result, the terminal d is coupled to the terminal blc of the microphone I by
following the path of j-h-b. As a result of seven voice power supply unit ll ') voltage is divided to
voltage divider Kfi voltage divider I (1, R1 lead terminals are moved in conjunction with the
operation knob provided on the microphone body Be (The electron of the extraction terminal of
the molecular group R is e, (IX), t! Of the extraction terminal to the molecular group
+ Is e, X, X-0 when the lead terminal is brought to the left in the 11% l At the output of the sound
field turtle gas conversion element only pressure is applied to the amplifier A, and also to the
right end When it is ready, it has a length of “′ ′ ′ ′ ′ ′ ′ ′ ′ ′ ′ ′ ′ ′ t′1fi−1− ′ ′,“ ff # fUl; I> p # tlxip ”. Fig. 2 Electrical connection of the input terminal of
amplifier A. It shows the field. ! , X == 1, that is, when the extraction terminal of each voltage
divider has (6) also on the right 18, the input voltage of the amplifier A is e ≦, and then the next
WK left 11 [fil moves, The output e1 from the microphone I gradually decreases, and the output
e1 'from the microphone I gradually increases to X-0, i.e., when the lead terminal reaches the
leftmost 9 only the output from 1 is Kn. When the terminal is brought to the right end again, only
the output eJ from 1 is distributed to the input of the amplification good. The output of the
amplifier A obtained by amplifying these inputs is transmitted to a recording head (not shown)
and recorded on a magnetic track provided at the edge of the film. As apparent from the above
description, if the microphone according to the present invention is used, the operation of the
operation knob K provided on the main body of the microphone switches the output between
MiGoo and the other audio power supply from K. Stone The two outputs can also be combined by
placing the position of the drawn terminal in the middle at an appropriate position g. The special
feature of the recording using the microphone according to the present invention is the S theory
and the ability to switch background music naturally and seamlessly (7). If this switching is
performed, the change in the recording level due to the delay of the circuits G, C, and the circuit
which is observed at the time of switching, amplification of noise and the like are completely
prevented. In the typical use of the microphone according to the present invention, first, the
background sound from the sound source l is constantly supplied and then the projector is
operated, the knob of the microphone body is operated by the microphone 時 に when necessary,
and the appropriate rL comment etc. Record and move the knob to VC background tone 倶 1 as
soon as you have finished Kenshin @ @ Sound endlessly? ′Tなうことである。 At this time, it is
not a matter of course that it is only necessary to operate the knob of the microphone main
frame at a distant position without stopping the projection. It is also possible to combine only the
microphone l and record only the commentary, and the sound-on-sound recording is also 5Jfunctional, recording the lC commentary on the film that has been previously recorded. Soundon-sound recording is the case where music etc. are recorded on film beforehand and the sound
is transmitted on it.
従, the microphone with the previous sound in a semi-erased state! A method is called to say that
the sound is superimposed from (8). Connect the molecular resistance bird and the withdrawal
resistor of the microphone according to the invention so that they can be connected to each
other for the numbering circuit of the recording gap, and in the case of X-0, the proper recording
state is achieved. VC recording (to) 1 It is possible to make an ideal sound 'on sound recording by
leaving the path V (associated and not recording when X = 1, ie nothing has been previously
recorded). (1) When the projector is in operation and all the sound from the sound recorded from
the film is recorded from the microphone, the sound from the microphone is 'M1', and if there is
no safety, the microphone resistance becomes X = 11C. Adjust and mask. At this time, the human
power a from the mike a unit AvctX is not obtained, and a large amount of @ 1; the road is not in
operation. Next, when inserting sa etc. from the microphone, Xf is gradually decreased. At the
same time, move the breakout terminal to the left in the figure. As a result, the part of the father
if6 bias current which has been recorded before the normal state WC gradually becomes erased
and the input from the microphone is recorded. If configured according to this, the problem of
always semi-erasure semi-recording (9) is solved, and the input from the microphone can be
naturally recorded at the desired location. When the need to record the input from the
microphone is improved by one, the lead terminal may be moved in the direction of X = 0 to X
knee 1 in the figure 6 in the figure.
