DESCRIPTION JPS58121896
[0001]
The present invention relates to an audio device that reports various fk reports through a
speaker, such as an audio calculator and an audio clock. In general, the problems with this type
of audio equipment are i) how to secure the sound pressure and sound quality of the speaker, ii)
how to make the equipment compact regardless of the attachment of the speaker, 1ii) for
speaker sound derivation How to make the opening of the cabinet in the cabinet without
compromising the design of the equipment. However, as shown in FIGS. 1 (a) and 1 (b), in the
case of the conventionally proposed audio device VC of this type, the speaker 4 is provided
adjacent to the inside of the upper cabinet 1 provided with the keyboard 2 and the display unit 3.
Since the opening 5 for deriving the speaker sound is formed in the portion corresponding to the
speaker of the cabinet, the sound pressure and the sound quality of the speaker can be secured
but the enlargement of the device can not be avoided, and the opening is further increased. Since
the parts are on the top of the cabinet, the design process is very difficult. Therefore, the object
of the present invention is to provide a voice device capable of securing the sound pressure and
sound quality of the speaker and realizing the miniaturization of the device while at the same
time facilitating the design processing along the opening for the speaker sound 4 output. It is in.
The feature of the present invention is that the space in front of the speaker main body and the
space on the back side are separated by partitioning means so that air vibration does not
propagate to each other, and they are built in the equipment cabinet, and the sound quality is
deteriorated due to vibration interference. , And all the generated sound can be guided to the
opening to secure the necessary sound pressure. Another feature is that the speaker main body is
disposed substantially opposite to the lower side of the input / output means provided on the
upper surface of the device cabinet and the speaker opening is provided on the side wall or the
lower end portion of the cabinet The present invention is to reduce the size of the main body and
to facilitate the design process associated with the opening. An embodiment of the present

invention will be described in detail with reference to the drawings. 2 (a) and 2 (b) are a plan
view and a side view of the voice calculator according to the present invention, FIG. 3 is a
longitudinal sectional view thereof, and FIG. 4 is an assembly diagram of the same portion. In the
figure, reference numeral 1 denotes an upper cabinet provided with a keyboard 2 and a display
unit 3, and 6 denotes a lower cabinet to which a speaker 4 is attached by a mounting bracket 7,
and these upper and lower cabinets 1.6 are formed at their edges It is comprised so that it can
integrate by engagement of. Air vibration propagates between the mounting means for mounting
the speaker main body 4 to the lower cabinet 6 and the space 11 on the front side (front side)
and the space 12 on the rear side (back side) of the speaker when mounted. It also serves as
partitioning means for partitioning.
In detail, a through hole 8 smaller than the outer diameter of the speaker main body 4 is formed
at the central portion, and the peripheral portion thereof is bulgingly formed in a step-like shape
so that the speaker main body can be fitted as shown. The retaining piece 12 formed on the
outer wall of the main body is formed on the mounting bracket side by fitting the speaker main
body in the step and then rotating it in the direction shown by the arrow in the figure. Is
designed to be engaged and fixed. Furthermore, bending pieces 10 bent in 7 directions are
provided on adjacent two sides of the mounting bracket 7, and the mounting bracket is
substantially opposed to the keyboard 2 of the upper cabinet 1 and from the bottom of the lower
cabinet 6 The length is determined so that the lower end portion of the bent piece 10 abuts on
the bottom surface when screwed to the upright post 13 0 or when screwing the mounting
bracket 7, the bracket The screwing positions are determined such that the two sides on which
the bent pieces 10 are not formed abut on the inside of the side wall of the lower cabinet 6
respectively. On the other hand, the opening 5 is bored as shown in the lower end of the side wall
of the lower cabinet in two directions in which the two sides of the mounting bracket 7 abut.
According to such a configuration, the speaker main body 4 is incorporated directly under the
keyboard 2 and the space 11 on the front side of the speaker and the space 12 on the rear side
are separated by the mounting fitting 7 so that air vibration does not propagate to each other. In
this state, the output from the front side (front side) of the speaker main body 4 is not interfered
with by the output of the opposite phase coming out from the rear side (back side) at all. The
opening 5 can be output. Therefore, the design processing can be made compact and the size can
be reduced, and the sound pressure and the sound quality can be obtained at the same level as
the conventional one. In the above embodiment, the speaker is attached to the lower cabinet with
the front of the speaker facing downward, but it may be attached upward. However, in this case,
the opening 5 needs to be provided on the side wall of the upper cabinet 1. Also, although the
opening 5 is drilled in only two directions, it may be drilled in three directions. As described
above, according to the audio device of the present invention, the device can be miniaturized
without losing the sound pressure and sound quality, and the opening does not have to be
provided on the upper surface of the device cabinet. It is possible to achieve an excellent effect
that is easy to perform.
