DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reverberant
microphone which obtains a remnant acoustic signal by the damping action of an elastic body.
Conventional Microphone Kf? The reverberation sound signal can not be written over, and if you
want to get the reverberation 1, the reverberation metal was done at the time of reproduction,
but today, make the remaining 4 I pipe to the sound reception signal and record it as a tasteful
sound Is desired. The purpose of this invention is to provide a reverberation microphone that is
easy to manufacture and easy to manufacture, as well as obtaining a good reverberation effect
(1). Eli, this (7) Tsujimoto's one! ! ! In the figure, 1 is a microphone case consisting of a hollow
circular comb with two openings at the upper end, near the mouth and in the case 1) ii: first 1.
Second diaphragms 2 and 3 are provided. An elastic member 4, for example, a coil spring, is
provided between the diaphragms 2.6, for example. A Chiri-Electric sound conversion unit 5 is
provided on the lower surface of the second diaphragm 3 in close contact with the inner surface
of the case 1, and between the vibrating portion 7 of the electric sound conversion unit 5 and the
second diaphragm 3. It forms a tight seal 6. The electric sound llI conversion unit 5 is a
conventional electro-acoustic conversion unit such as a Tainamig type or Conden V type. Next, to
explain the operation of the distribution-embodiment, the sound entered from the upper opening
sword of the case 1 is received by the first diaphragm 2 and vibrates the 71 diaphragm 2. And,
the movement of the elastic body 4 (and 71. The second tire 7 ram 3 is transmitted to the second
tire 7 ram 3 via airborne propagation between the second tire 7 ram 2 and 3. The air in the
closed chamber 6 is vibrated by the vibration of the second diaphragm 3, and the carrier
movement portion 7 of the electric sound to conversion unit 5 is vibrated by the air conduction =
VC, and a 箸 -signal can be obtained. At that time, the elastic body 40 damps and vibrates to

make the diaphragm 2. Since #i residual luster remains, the reverberation signal is obtained from
the electric-toning conversion unit 5. In the above-mentioned embodiment, the friend may use
two diaphragms 2.3, but this may be one, in which case one end of the inertia body 4 is
supported by the case 1 . As described above, this invention is good because it accommodates the
diaphragm connecting the elastic body and the electroacoustic transducer unit in the microphone
case and the electroacoustic transducer unit in the microphone case, and a sealed chamber is
formed therebetween The electroacoustic transducing unit can be easily inserted into the case (3
nd in order to obtain a reverberation-placed III signal and not to attach the W contact elastic
body to the vibrating portion of the electroacoustic transducing unit). is there.
