BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view showing an embodiment of the
present invention. FIG. 2 is a longitudinal sectional view of FIG. FIG. 3 is a partial cross-sectional
view of FIG. 1 иии Microphone body, 1c и и и и и и и и и и и и и и и и и и Spring type reverberation unit
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reverberation
microphone which produces a reverberation effect by transmitting an electrical signal with a
time delay. Attach magnets to both ends of the coil spring and vibratably support the magnets in
the coiled core respectively, and use one of the coils as a drive rod and the other as a pickup rod
to delay the transmission of electrical signals A reverberant microphone has been developed in
which a spring-stainer unit has been incorporated into a rod-like microphone body. In this device,
the microphone unit is incorporated in the front (1) / 7 <'/ 75) image of the microphone body,
and the electronic circuit and the spring type reverberation unit are incorporated adjacent to the
microphone unit, and the diameter is further reduced. It is common to incorporate a battery in
the formed microphone body O grip portion. Such a generally rod-like microphone is used by
grasping its reduced diameter gripping portion, or when it is used as the center of the gripping
portion of the user or the microphone, spring type reverberation If the acceleration due to these
movements becomes large because the unit is incorporated at a position farther than the grip
portion, the inertia of the spring of the reverberation unit during the inertia of the reverberation
unit causes the spring of the reverberation unit to vibrate greatly, which is unpleasant noise Left
the problem that would occur. The present invention solves the above-mentioned problems, and
it is considered that the spring type reverberation unit is incorporated in the grip portion of the
microphone body. Hereinafter, the embodiment of the present invention will be described by the
drawing v12. ??? In FIGS. 1 and 2, a microphone unit 2 for converting a sound wave into an
electric signal is incorporated in the rod-like microphone main body 10 head 1a, and the
microphone 1 is printed in the entire microphone main body 1 [5 is incorporated. An electronic
circuit angle including an amplifier or the like attached to the printed circuit board 5 is

incorporated in the i [l 11 all of the microphone main body 1 and a battery box 5 for
accommodating a battery is incorporated adjacent to the electronic circuit 4 . The tail portion 1b
of the microphone body 1 is formed with a grip portion 1C which is easy for the user to hold by
hand, and in the grip portion 1C of the microphone body 1, the spring 7 of the spring type debris
unit 6 is gripped portion 1c. In the longitudinal direction (: arranged, the spring-spring
reverberation unit 6 is mounted and incorporated in the printed board 3).
Ceramics, spring W! ! Magnets are attached to both ends of the coil spring as the reverberation
unit 6, and the (3) '-) magnet is vibratably supported in the core wound with each coil, one of the
coils is used as a drive rod and the other is used as a pickup Therefore, if the construction for
delaying the transmission of the electrical signal is used or the construction for delaying the
transmission of the electrical signal using the spring 7 is used, the spring type reverberation unit
6 having any construction is used. Is also good. As described above, since the present invention
incorporates the spring type reverberation unit in the grip portion of the microphone body, even
if the user moves the grip portion of the microphone body as a center, the spring type
reverberation unit is positioned at the spring or rotation center portion. As the acceleration
applied to the spring type reverberation unit decreases, the inertial force also decreases, and
unnecessary vibration noise can be eliminated. In addition, a relatively heavy battery is provided
on the am side of the microphone (since the center of gravity of the microphone is in the vicinity
of the head and the hand feels a sense of weight especially when moved, A) It can increase the
sense of weight or high-quality image of the microphone. Furthermore, batteries, electronic
circuits, and reverberation units can all be mounted on a single integrated printed circuit board,
and most of the wiring can be installed via this printed circuit board, simplifying assembly and
improving production efficiency. It can be done.
