BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a partial cross-sectional side view showing a
conventional speaker attachment portion, FIG. 2 is a cross-sectional view showing a portion
where the built-in microphone is attached, and FIG. 3 shows an embodiment , And FIG. 4 is a
sectional view taken along line C - C in FIG. 3. 1 ... Case body, 2 ... speaker, 3 ... speaker fastening
fitting, 11 ... microphone holding rubber, 12 ... built-in microphone .
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention relates to a
tape recorder having a speaker and a built-in microphone, wherein a speaker is attached to a
speaker and a built-in microphone at the same time by metal fittings.

is, the speaker 2 in the case main body 1) a speaker holding Jffi 5 - t '- 4 bE engaged with the
case main body 1 integrally formed with the case main body 1 holding n and am are fixed to the
fixing tapping screws ff 21 a' c 61.37 2 2 4 by the speaker fastening bracket 3 which is fixed by
the screw 4. On the other hand, as shown in FIG. 2, the microphone holding rubber 11 for
preventing vibration is fitted to the built-in microphone 12, and the built-in microphone is
attached to the outer periphery of the microphone holding rubber formed integrally with the
case body 1 And the microphone retaining rubber 11 is fixed to the boss 1b by the microphone
fastening member 6 mounted by the tapping screw 7. A positioning boss 8 of the microphone
fastening 6 is formed integrally with the case body 1. Reference numeral 9 denotes a lead wire of
the built-in microphone 12. However, in the conventional configuration as described above, since
both the speaker 2 and the built-in microphone 12 are mounted by using dedicated fasteners, the
number of parts increases and the number of assembling steps also increases, and in addition, It
was a matter of necessity. The present invention aims to solve such conventional drawbacks jl,. It
is "-", which is shown in FIG. With reference to FIG. 4. In FIGS. 3 and 4, the same reference
numerals are attached to the same components as those of the conventional construction of FIGS.
1 and 2, the present invention is characterized in that the speaker fastener 3 is formed in an L

shape, The speaker 2 is restrained by one end portion of the metal fitting 3 while the holding
rubber 11 of the built-in microphone 12 is restrained by the other end portion of the speaker
fastening metal 3. The center portion of the speaker fastening metal 3 is fixed to the boss 1 a of
the case body 1 by the tapping screw 4 and the positioning boss 13 formed integrally with the
case body 1 in the hole 3 a provided at the other end thereof The upper end protrusion 13 a is
fitted and positioned. As described above, according to the present invention, the speaker and the
built-in micro- ,,, ', 7. *7を′″″′。 "° ° n 7 n gold AK '" - Mounting' '' '19', so that the builtin microphone fasteners are unnecessary compared to the conventional ones and only
assembling can be done by installing one ° 0 speaker fastener Therefore it is very easy to
become 44, it is also possible to miniaturize, its utility is great.
