Description of Invention
Acoustic device for portable electronic devices
DETAILED DESCRIPTION OF THE INVENTION The invention Fi The acoustic device of the
portable electronic device is a structure Kra which belongs to it. In addition, by making it a
simpler structure K, downsizing and thinning-inexpensive maintenance, and further multifunctionalization and use letter B! The purpose is to provide better products, such as producing
sufficient sound pressure. In response to the rapid spread of microcomputers and energy saving,
electronic devices are now more multifunctional, smaller, longer in life, etc. High, convenient, and
portable in one day. In particular, it is popular to use a style that uses sound synthesis techniques
to squeeze the pronunciation e ability. A variety of surprise products, toys, tables, watches,
measuring instruments, etc. are used to use this function. EndPage: 1 It is possible to further
enhance the commercial value by adding a pronunciation function to this information display
function. The present invention will be described in detail for a typical watch. Recently, due to the
demand for diversification of designs, the design has been reduced in size and thickness, and it
has been designed to be multifunctional by using a microcomputer, and the alarm S rudder is
also becoming more sophisticated. On the other hand, Price reduction is rapidly being achieved.
From such a situation, it is a tendency to use an electric device that produces an alarm function.
The present invention is this pressure! The structure of an acoustic device using an i transducer
will be described in detail according to the embodiment using ρb. FIG. 1 shows a principle of
operation based on a bending vibration of a sounding body in which piezoelectric vibrators
which extend and contract in directions opposite to each other in the outer direction are stacked
and integrated in the outer direction as a sound source. Applying this principle to a transparent
or see-through piezoelectric vibrator-to form a see-through electrode, this sounding body itself 1!
Combined with the cover function of one instrument display procedure! -It is intended to press
down thin and small equipment. Use this pronunciation body V! Example 1-shown from FIG. 2 &
FIG. Fig. 2 shows an acoustic device in which a sound generator 2 is mounted with 4 dial rings
via 3 glass pads by laminating and warping 2α and 2b-piezoelectric vibrators to 1 vitreous acid
so that it can be seen through. Configure and mount through the 6 waterproof ring to the 5 case.
The conductive relay members 7 and 8.9 to be press-connected to the large power leisure
electrodes formed on the piezoelectric vibrators 2a and 2b in the dial ring 4 are held by the
insulating members 1 (1, 11 ( 8 # 'i Because it is grounded, insulation is not necessary.
Further, the step portions 7α, 8α, 9α are provided so as not to deviate from the relay member
7.8.9 for conduction, and the guide ring, position, and arrangement are movably movable in the
axial direction by the dial ring 4. Continuity relay # 7,. A circuit board object having electrodes
12α * 12b @ 12c to be crimped and conducted to the tips of 8 and 9 is fixed to a base frame of
13 to constitute an apparatus main body, and 14 back pigs are 5 through 15 back pig patches. It
fixes to a case and comprises an exterior means. The 16 dials fixed to the main body of the
instrument hold a hole or notch fW of 16α, accommodate the relay member 7 and 8.9 for
conduction, and also the second hand 2 of the balance 17 with the piezoelectric vibrator 2b, The
18th minute hand and the 19th hour hand are arranged. In addition, it is more effective to
arrange the pressure transmitting conductive member with the W pole of Fiuα, 12b and 12C,
and to make false the relay junction part 導 通 for 7 and 8.9. . The battery 1 circuit means for
power supply is omitted since it is the same as an ordinary watch. FIGS. 3 to 5 will now be
described with reference to FIG. 2 differently from FIG. FIG. 3 shows that the glass edge of l is 5
which passes through the input take-up electricity fiKEE formed on the outer surface of the 2cL
piezoelectric vibrator 1 at t 'using the vitreous acid of 1 instead of the relay part # 9 for
conduction. 8 Ew is conducted to one of the 20ρ conduction coupling members received in an
insulating manner in the case, and the press-contact conduction is smoothed to one electrode of
the (gr + path substrate 12 c formed busy) of Fi 12. The case of JiI4rllJFi5 has a structure in
which the dial ring 4 is also used, and is held by the case of the relay member for continuity # i5.
The fifth sum is a structure in which the case of g doubles as the dial ring of crow edge and 4 of
1; It is mounted on a 50 case via a digital display type watch in which 21 liquid crystal panels are
disposed under the 2 sounding body. In addition, it is easy to provide the structure of the relay
means for conduction in which the relay member for conduction of 8.9 works to be shifted
within a range of 900 to about 180 ′ in plan view, and also the input lever for input of the
sounding body of 2. It is possible to roughen the built-in angular pupil lens on the rod. In the
present invention, the pressure of the two sheets stacked can be incorporated by increasing the
external shape of the vibrator by enlarging the external shape. Then shape it into 2 sounding
bodies! An embodiment of the pole is shown in FIGS. 6 to 1θ. Figure 6 (support) · Figure 2 2c on
the upper surface of the pressure tS mover of 2α, 2d on the lower surface, 2d on the upper
surface of the piezoelectric vibrator, sharing 2d on the lower surface, the lower surface Form
twenty-six visible drive electrodes.
In addition, an electricity '1 # 2 y for electrically connecting the electricity 82c and the electrode
2f is formed on the outer peripheral side surface of the 2G piezoelectric vibrator. The electrode
2f is an input taking-in electrode formed in a band shape about a half circumference around the
outer periphery, and in the electrode 2d @ 2 #, the vicinity of the outer periphery also serves as
an input electrode for inputting. This structure can be quickly applied to all the structures
EndPage: 2 of FIGS. Fig. 8 shows the drive for the pole 2c, 24.2g on the whole surface of the
electrode type ashing surface of the piezoelectric vibrator for manpower insertion! Suitable for
the structure of Fig. 3 with lR construction without the need for poles. 9 and 10 have the same
electrodes as in FIG. 6, or have two notches 2h provided on the lower EEI vibrator 2b to form a
storage space for the conductive relay member 8 ° 9 Fig. 5 外 装 reaches the exterior structure
of the deformed shape. In addition, by forming a hard, transparent i-second protective layer on
the upper surface of the t-pole 2c, it is possible to further enhance the durability (not shown in
the drawing). For example, the sound generator is configured by stacking two transparent
squeezable pressure sensors, and the sound generator is combined with a cover of an outer cover
to make it thinner and to sound an alarm etc. Functions can be added to forgiveness. In addition,
space efficiency that enables miniaturization and thinning with easy design is clear, and by
matching the sound emission part to the display part of the clock, the visual and auditory
directions can be matched. Digital clocks have a wide range of continuous use to analog clocks,
such as being able to spread the sound surface and have no drop in the sV field. With a wide
range of multi-If, such as all rear-arm TV and the application range to the field mentioned in the
opening paragraph 1 as' LX) k% sound φ device with a few component parts, and while trying to
diversify design It is easy to standardize, and cost reduction can be achieved because parts cost is
low. Even when parts are supplied by after-sales service, the size of the sounding body can not be
reduced by the use of a glass pad, and it is possible to provide a single sounding body.
Maintenance fees can be achieved.
