DETAILED DESCRIPTION OF THE PROBLEM The present invention relates to a small electronic
device having a sound-recording function. For example, in the electronic wristwatch with a sound
function, as shown in Fig. 1, the nine circular shapes according to the shape of the sounding body
are divided into 1 - Ni - ken 0 ° / NO / / / 2 t. Which is eccentric with respect to the center of
the circle and has a sounding body such as a piezoelectric buzzer provided inside the resonance
box having the sound emitting tube n at the ninth circular edge position. In the wristwatch with a
sound function, as shown in Fig. 2 (shown on al, display I on the upper wall peripheral part of the
watch case C! ID is avoided to form a sound output port I. In case of using the pronunciation eni,
if the company sounds the sound emitting tube B to be rounded at the periphery of the
resonance dam, the resonance box at the periphery of the clock tur 00 There is an advantage
that it is possible to arrange the resonance MA at the inner peripheral portion of the watch case
C without requiring a wide arrangement space (for the purpose). Thus, when storing the abovementioned pronunciation unit in the no-tops of the hour hand jule provided inside the hour hand

accommodated therein. Furthermore, as shown also in FIG. 6 (a) I (b), sound generating unit
housing portion 7 d Vc sound warning sound eni y) j (1 is stored in housing 1 is sound
generating unit 1 - The sounding body zsVt is provided inside the resonance box 21 having the
cylinder 21. Resonance box 8 - 'fuJfj?
s bottle. For example, the quasi j 522 is a tortoise made of a synthetic resin, and the sounding
body 2J has a circular shape in order to enhance the pronunciation effect, so it is formed as a box
body which makes a planar circular shape compatible with this sounding body shape, And at the
position 03 eccentric by a predetermined distance with respect to the circular center 01 of the
resonance box J 2 in the Wli portion, a sound emitting cylinder 21 forming a cylinder having a
raised upper end opened is formed integrally upward. In the embodiment, the outer peripheral
line of the sound emitting tube XXO coincides with the outer peripheral line of the resonance box
XSO. A round protrusion j4 forming a concentric circle with the sound emitting cylinder 16 is
integrally formed on the outer peripheral portion in the middle of the sound emitting cylinder
320 in the height direction so that the To and the O protrusions 14 are surrounded by the outer
circumference of the resonance box 22 (That is, projecting height from the outer periphery of the
sound emitting cylinder 21 - S>), and the portion facing the rim portion of the protruding portion
j 4 o resonance box JJ protrudes to the outside of the resonance box 12) . In this way, when
looking at the resonance box 1 z in a plan view, the 0 sounding body 2 S in which a part of the
protrusion J 4 protrudes outward in an arc shape from the outer periphery of the circle of the
resonance box 110 is, for example, a piezoelectric puddle is used 9 - L @ 'n-knee 5 is held in the
resonance box 2 j, the storage section 14 is provided on the circumferential side of the housing
10 corresponding to the upper peripheral portion of the watch case 1 forming the sound output
port 5 Section, which is open at the top so that it can be inserted and inserted from the upper
side, so that it is a nine concave part. The storage portion ya is formed, for example, over the
bottom portion of the washing 1 and the peripheral wall thereof and has a depth corresponding
to the height of the whole resonance box 22 including the sound emission tube 21, and the
bottom portion 7 (1 ° corresponds to the resonance box XX It is a circle that has a diameter.
Storage section yac) A groove Fd having an arcuate cross section is formed along the vertical
direction at the position facing the sound output port 5 of the watch case 1 on the
circumferential wall of the housing 10 having an arcuate concave shape at the top of the bottom
part yai It is. The groove yaI corresponds to a part of the protrusion 914 protruding from the
outer periphery of the resonance box 22. That is, if a circle having the same diameter as 14 is

drawn around a position eccentric with the same distance from the sound emitting cylinder 21
with respect to the circular center of the bottom y 4 H, a part of this circle is the outer
circumference of the bottom 1 iFd * To protrude to the outside, this protruding part is called a
groove yd. 1 O - IQ $ 97 m #. The groove Fl is opened on the upper surface of the peripheral wall
of the housing 10 and at least t is high from the upper surface of the peripheral wall 14 to the
height 1! , And the sound resonance box 12 is arranged to be inserted into the bottom mud of the
storage section 1 d from above and the sound emission @ XZ is stored in the storage A groove
Fdlj (opposed to the peripheral wall of the housing 1 of the portion 74 and opposed to the
protruding portion 24 and protruding from the outer periphery of the resonance box 22 is
inserted into the grooves ya wealth from above and engaged therewith.
That is, the resonance box 22 is set in the accommodating section 74 with setting the
loudspeaker 210 position 11 lil so that a portion protruding from the outer periphery of the
protrusion J 4 C 1 resonance box 21 engages with the groove ya. In this case, since the groove
ras is formed by setting the position so that the sound emitting 1i 1121 comes directly beneath
the sound emitting port 5 of the watch case 1, by the holding of the projecting portion 24 and
the groove Fd The sound tube 21 faces the sound output port 5 and is positioned just below the
sound emission port 5 and positioned and fixed. Also by holding the protrusion 24 and the
groove Fd) Push the resonance box 21 to the detent 11-108 α 'so as not to rotate in the
circumferential direction at the bottom yall c, the pedestal, the sound emission tube On the upper
part of JIO, a tubular parallelepiped, king 25 was fitted and inserted in support of the protruding
part 34, and the upper end of this ·, Zhong ZSO surrounded the sound output port 5 to the inner
wall of the wall of the watch case 1 The band is thinned to block the sound output port 5 from
the inside of the watch case 1. It should be noted that the sounding body of the pronunciation "y)
J # is connected to the circuit board 90 circuit. When the sounding body 11 of the pronunciation
enity y) J 4 is driven by a signal, the air inside the resonance box 22 vibrates to generate a sound,
and after passing through the tone and sound emission cylinder 21, the sound emission port of
the watch case 1 5 to the outside. When incorporating the pronunciation enit JO inside the watch
case 1 in this electronic wristwatch, by inserting the resonance box 1 j from the upper side of the
protrusion 1114 sounding groove it K and inserting the resonance box 1 j from above into the
housing 10 housing part rd Shi, the sound emission @ ZX is positioned at the position
corresponding to the sound output port 5 of the watch case 1, and at the same time, the
resonance box j 1 is stopped so as not to rotate and the storage section! - It can be stored in. 12 (· · · bow, 0918 · · ·), note that the protrusion provided on the sound emitting tube of the
resonance box is formed integrally with the sound emitting tube and is formed as a separate
body and a sound emitting tube , Or the like may be fixed by means such as adhesion or the like,
the central part of the outer periphery of the sound emitting tube O may be ring-shaped 40, but
it may be any shape as long as it forms an arc shape protruding at least from the outer periphery
of the resonance box 0 Sounding body can also be used electromagnetic buddy 0 Pronunciation
Unit storage section is not limited to the embodiment but may be formed directly in the

equipment case of hut electronics 0 The invention is not limited to the electronic wrist watch, It
can be widely applied to hut electronic appliances equipped with a sound recording function. As
described above, according to the compact electronic apparatus with a sound function of the
present invention, by simple operation of inserting and engaging the protrusion formed in the
sound emitting tube of the resonance box into the groove formed in the storage part, It can be
positioned so as to face the case O sound emitting port to prevent rotation and to accommodate
the resonance box in the storage portion. For this reason, it is possible to easily and certainly
incorporate the sound emitting diaphragm using a resonance axis having a circular form and a
decentralized emission func- tion facing the sound output port into the equipment case Turtle 13
