DESCRIPTION JPS50142427
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram showing an example of
an acoustic device according to the present invention, a cross section of which is a part. In the
figure, 1 indicates a case body, 2 indicates a plate surface, 3 indicates a vocal hole, 4 indicates a
speaker, 5 indicates a diaphragm, and 1 W indicates a microphone. −61ー
DETAILED DESCRIPTION OF THE INVENTION The present invention is an acoustic device Kll
incorporating a speaker and a microphone in a case body. Such an acoustic device can be found
in a small 1 ull tape recorder if it is kept. Therefore, in the following, in the conventional sVB tape
recorder, the speaker and the microphone H7f / are juxtaposed to the plate surface of the case
body in the conventional sVB tape recorder. It is arranged as normal, so the case body is a space
for arranging a speaker and a microphone and a microphone for f6. う□お、。 5,2 為-+115. The
door 'f, with a certain limit to miniaturize 19'. As a matter of fact, this is a new addition to the
building that combines a separate sound collector with this to improve the sound collection effect
of Oikulo 7 on. Therefore, the present invention can be miniaturized as a whole compared to the
conventional magnetic tape recorder of the prior art, and such a magnetic tape recorder which
can obtain an excellent microphone sound collecting effect without combining a separate sound
collector. It is intended to be proposed and will be apparent from the description of the actual
wheel fIlt of the present invention in detail in the following drawings. In the figure, U indicates a
magnetic tape recorder as a whole, and a speaker and a microphone which are disposed as
described later in the case body 1 have a built-in drive mechanism for driving a magnetic tape, a
magnetic tape, and a magnetic tape. The tape has a magnetic head, a recording amplification
system, a reproduction amplification system, etc. which are made to contact or be separated from
the tape, and the pre-write signal from the microphone at the time of recording makes a
recording amplification system-magnetic head. Recorded on magnetic tape through. 12) "Be,
child" Also, at the time of reproduction, an acoustic signal reproduced from the magnetic head is
supplied to a speaker via a reproduction amplification system to obtain a reproduction sound. In

such a magnetic tape recorder, a speaker and a microphone are disposed in the case body 1 and
incorporated in the case body 1 as described below. That is, for example, a small number of small
holes, ie, small holes, are formed in the plate surface of the case body 1 indicated by reference
numeral 2, and a small number of small holes are formed in the plate surface 2. A speaker,
indicated by reference numeral 4 from the inside, is mounted at the position where it is located.
In this case, the type of speaker 4ri can be applied, but its diaphragm has a conical diaphragm Jr
ヲ as shown by the reference numeral 5, and thus the speaker 2 has its conical diaphragm 5 And
is attached to the plate surface 2 in a relationship facing the discharge hole 6. Also, as shown by
rf 18 as a microphone 13-(for example, electret W-v microphones having a size sufficiently larger
than the diameter of the open end face of the diaphragm 5 of the occupied speaker 4), such a
microphone 8 is The sound receiving surface 9 is mounted inward at a position corresponding to
the front position of the diaphragm 5 of the speaker 4 of the plate surface 2, and is disposed at
the front position of the diaphragm 5 of the speaker 4.
Although the above is an example structure of this invention, according to such a structure, the
sound radiated from the diaphragm 5 of the speaker 4 is transmitted to the outside surface of the
case body 1 through the discharge hole 6t- It is also clear that the sound from the outside of the
case body 1 is incident on the sound receiving surface 9 of the microphone 8 through the voicing
holes 31 formed in the printing plate 2 so that the sound from the outside of the case body 1 is
radiated. As a result, the sound signal from the microphone 8 is recorded on the magnetic tape,
and the speaker 4 can reproduce the reproduced sound as it can be played back. In this case, the
microphone 8 is disposed in front of the diaphragm 5 of the speaker 4 and the speakers 4 and
41 are supplied? Since the space for disposing the microphone 8 is shared, the case body 1 is
miniaturized as a whole. Also, since the diaphragm 5 of the speaker 4 viewed from the
microphone 8 acts as a sound collector, an excellent sound collection effect of the microphone 8
can be obtained without special installation of a separate sound collector. It is a book with great
features such as not having to be specially installed in the entire case. Therefore, according to the
uninvention, the whole can be miniaturized sufficiently in comparison with the conventional
magnetic tape recorder, and a speaker and a microphone which can obtain an excellent
microphone sound collecting effect without combining all the sound collectors separately It has a
great feature that makes it possible to obtain a built-in magnetic tape recorder. In the above, the
case where the microphone 8 is attached to the front position of the diaphragm 5 of the speaker
4 of the plate surface 2 of the case body 1 has been described, but 9 is not shown but the front
position 51 of the diaphragm 5 of the speaker 4 − · · 飼 If you keep it evenly so that the
vibration of the diaphragm 5 is not adversely affected, it is possible to extend the support from
the back azimuth of the speaker 2 and attach the microphone 8 to it, of course The microphone 8
is not limited to the electret type described above, but may be of another type. My father
mentioned above that the preceding equipment was described as a magnetic tape recorder, but it
is also obvious that the present invention can be applied to audio equipment of the type that
incorporates a speaker and a microphone. .
