DESCRIPTION JPS5952994
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
mini-portable stereophonic sound reproducing apparatus. The structure of the prior art and its
problems In general, it is widely known that a portable type stereo sound reproducing apparatus
is provided with several speakers for each of the left and right channels on the right side of the
cabinet and a recess for cassette storage and a cassette mechanism block in the center. ing.
However, although this type of portable type is very large although it is a portable type, a very
small portable type stereophonic sound reproducing apparatus which can be suspended at the
waist or carried in a pocket is also known. However, since this type of cabinets are very small,
they often do not have speakers for the left and right channels, so it is necessary to use a
separate headphone when listening to stereo playback sounds. There was a problem. SUMMARY
OF THE INVENTION The present invention is to eliminate the above-mentioned conventional
drawbacks, and it is an object of the present invention to miniaturize a cabinet and further to
make it possible to easily attach speakers of left and right channels in the cabinet. It is said that.
In the present invention, a cassette lid is provided openably and closably at the front center of
the cabinet, and a cassette storage recess and a cassette mechanism block are provided inside the
cassette lid, and sound emitting parts are provided on both sides of the cabinet. The cassette
mechanism pro is housed in the back space of the flat plate portion which accommodates a
vertically long flat type speaker in which the voice coil portion is provided in one side of the
cabinet facing the sound portion and the voice coil portion is offset to one side. A motor section
and a dial block section protruding from the y axis are arranged. A vertically long flat type
speaker is provided close to both sides of the cassette housing recess, and the back of the flat
section without the voice coil section is effectively used. And, therefore, it is possible to
miniaturize as much as possible, and it is possible to perform stereo reproduction with built-in
speakers. It has the advantage of that. The illustration of the embodiment shows an embodiment

of the portable stereophonic sound reproducing apparatus of the present invention. In the figure,
1 is a cabinet main body, The cassette mounting part 2 is formed in the front center part, The
speaker sound emission parts 3a and 3b are formed in the both sides. The cassette mounting
portion 2 is provided with a cassette lid 4 which can be freely opened and closed. The cassette lid
4 has substantially the same width as the vertical width of the cabinet body 1 and almost
completely covers the cabinet body 1 when viewed from the front. It is formed.
The speaker sound emitting portion 3 is formed to have a longitudinal length substantially the
same as the upper and lower dimensions of the cassette lid, and a rectangular sound emitting
hole 7 provided in the front cabinet 6, the speaker 8 mounted therein, and the front And a net 9
attached to the The cassette lid 4 has a see-through window 11 for displaying a dial along with a
see-through window 10 for tape winding confirmation, and a dial scale plate 12 is attached to the
back of the see-through window 11 for dial display. And the pointer 13 is configured to be
transparent. The pointer 13 is driven by the operation of the dial operation knob 14. FIG. 2 is a
perspective view of the state where the cassette lid 4 is opened, and in the area covered by the
cassette lid 4, a cassette storage recess 15 is provided. Then, a long hole 17 is formed in a range
covered with the front cabinet 60 cassette lid 4 in which a predetermined cassette drive device
such as a reel shaft 16 is installed in the cabinet node 1 to face the recess 15 of The pointer 13 is
configured to be transparent through the long hole 17. The position where the long hole 17 is
formed is a position corresponding to the see-through window 11 provided on the cassette lid 4,
and the pointer 13 provided on the front cabinet 6 can be seen from the outside even when the
cassette lid 4 is closed. 3 is a longitudinal sectional view of the right side sound emitting part 3a
in FIG. 1, and FIG. 4 is a longitudinal sectional view of the left side sound emitting part 3b. In FIG.
3, the speaker 8 is a rectangular flat plate speaker having a rectangular flat diaphragm 18, and a
voice coil portion 19 is provided at a position (downward in the illustrated example) at the back
of the flat portion. The mounting frame 20 provided on the front cabinet 6 is attached to the boss
21 provided on the front cabinet 6 by fastening with screws 22. A dial 24 comprises a chassis
24, a variable capacitor 25, a dial drum 26, a pulley 27, the dial control knob 14 and the like
mounted on the printed circuit board 23 in the back space of the flat plate of the speaker 8
without the voice coil 19. Block parts are arranged, and the dial rope 28 wound around them is
connected to the pointer 13. In FIG. 3, reference numeral 29 denotes a back cabinet, 30 denotes
a battery storage unit, and 31 denotes an aluminum decorative board provided on the front
cabinet 6. In FIG. 4, the bee force 8 is constructed in the same manner as that shown in FIG. 3,
but the voice coil portion 19 is reversely mounted so as to be three-way. Therefore, the lower
side is only the flat plate portion, and in the back space of this flat plate portion, the motor
portion comprising the motor 33 projecting from the cassette mechanism block 32 provided
opposite to the cassette storage recess 15 and its mounting plate 34 Is arranged.
A second printed circuit board 36 constituting a motor drive circuit and the like is attached to the

support plate 34 of the motor 33. FIG. 5 is an explanatory view showing the relationship between
the blocks as viewed from the front with the front cabinet 6 removed. In FIG. 5, reference
numeral 36 denotes a chassis of the cut mechanism block 32 provided in the cassette storage
recess 15 and serves as a base on which the cassette operation button 5 and the reel shaft 16 are
attached, and constitutes the cassette mechanism block 36. A motor mounting plate 34 is
integrally provided on the cassette mechanism block 36 so as to protrude in the lateral direction,
and the motor 33 is mounted on the mounting plate 34. The guide 37 of the pointer 13
connected via the dial rope 28 on the dial block side is disposed between the right side speaker 8
and the right end of the cassette mechanism block 36, and the pointer 13 is the cassette M4 as
described above. It is comprised so that it can drive ¦ work corresponding to the see-through
window 11 for dial displays. In FIG. 5, reference numeral 38 denotes a left and right microphone
mounting position, and 39 denotes a counter. According to the present invention, a vertically
open cassette lid is provided at the center of the front of a cabinet, and a cassette mechanism
block is provided inside the cabinet lid, and a voice coil portion is provided on one side of the
cabinet at one side. A flat type speaker is attached and a motor section protruding from the
cassette mechanism block f and a separately provided dial block section are disposed in the back
space of the flat section of these speakers, and the voice coil section of the speaker is avoided It
is possible to significantly reduce the overall size of the cabinet as a whole by effectively using
the rear space of the cabinet, and even though the speakers for the left and right channels are
built in, they can be suspended at the waist or stored in pockets It has the advantage of being
able to be a portable ultra-compact stereo device. In the case where a dial display pointer guide
portion is provided between the recess for storing the cassette and the speaker sound emitting
portion as shown in the embodiment and a transparent display window for the dial display is
provided at the corresponding position, the space is narrow. Moreover, it becomes possible to
construct a stereo sound reproducing apparatus with a very small radio, while maintaining the
overall balance of providing a speaker sound emitting part in proximity to both sides of the
cassette lid, and the effect becomes even more dog-friendly .
