Thus, several other techniques for closing the opening of the microphone formed in the housing
are known.
However, in the field of portable telephones, the main purpose is to make conversations via
microphones, and there is no way to predict when incoming calls will occur.
From such a circumstance, the opening of the microphone is, of course, always open as a
technical common sense at the time of filing of the present application, and there is only a sense
of value as appropriate.
[0006]
An object of the present invention is to provide a new idea that overturns such a fixed idea.
[0007]
According to an aspect of the present invention, a mobile phone comprises a housing, and a
microphone housed in the housing for inputting voice.
The housing is formed with an opening serving as an acoustic terminal of the microphone.
The mobile phone further comprises a removable waterproof cap for opening or closing the
opening.

[0010]
(Straight-Type Mobile Phone 1) As shown in FIG. 1, the touch-panel-type straight-type mobile
phone 1 (mobile terminal or mobile phone) includes a housing 2, a screen 3, a microphone unit
5, and a connector unit 7. It is composed of The screen 3 is provided on the front surface 2 a of
the housing 2. The microphone unit 5 is provided on the bottom surface 2 b of the housing 2.
The connector portion 7 is provided on the side surface 2 c of the housing 2.
[0011]
(Case 2) As shown in FIG. 3, in the case 2, a microphone 8 as a conversion element for converting
a sound wave into an electric signal is accommodated. That is, the microphone 8 is for inputting
voice. An opening 9 which is an acoustic terminal of the microphone 8 is formed on the bottom
surface 2 b of the housing 2. Then, as shown in FIG. 2, the housing 2 is provided with a
removable waterproof cap 10 for opening or closing the opening 9 shown in FIG. 3.
[0012]
(Microphone Unit 5) The microphone unit 5 is realized by the housing 2 in which the opening 9

is formed, the microphone 8 and the waterproof cap 10.
[0013]
As shown in FIG. 4, the waterproof cap 10 is configured of a cover portion 11, a press-fit portion
12, and a drop prevention portion 13.
The cover 11 is for closing the opening 9. The cover portion 11 has an area slightly larger than
the opening area of the opening 9. The press-fit portion 12 is for holding the cover portion 11 in
a waterproof state in which the cover portion 11 is in close contact with the side surface 2 c of
the housing 2. When the press-fit portion 12 is press-fit into the opening 9, the cover 11 is held
in a waterproof state in close contact with the side surface 2 c of the housing 2 while closing the
opening 9. The detachment prevention portion 13 is for preventing the cover portion 11 from
being separated from the housing 2 and being lost when the press-fit portion 12 is extracted
from the opening 9. The one end of the detachment prevention portion 13 is connected to the
cover portion 11, and the other end is connected to the side surface 2 c of the housing 2. In this
configuration, the waterproof cap 10 may be removed from the housing 2 at the start of a call,
and the waterproof cap 10 may be attached to the housing 2 again at the end of the call.
[0014]
(Screen 3) As shown in FIGS. 5 and 6, the screen 3 is configured by the LCD 14 as a display
panel, the vibration panel 15, the transparent piezoelectric sheet 16, the gasket 17, and the
vibration element 18. .
[0015]
The vibrating panel 15 is a transparent panel that is elastically supported by the housing 2 via
the gasket 17 and that can generate sound waves.
[0016]
The transparent piezoelectric sheet 16 is a sheet-like assembly of piezoelectric elements for
adding a function as a touch pad to the screen 3.
[0017]

The gasket 17 is annularly formed of, for example, a silicone elastomer or a urethane elastomer.
The gasket 17 is interposed between the vibration panel 15 and the housing 2 and causes the
housing 2 to elastically support the vibration panel 15.
[0018]
The vibrating element 18 is mounted on and bonded to the vibrating panel 15 to convert an
electrical sound signal into acoustic vibration.
[0019]
In the present embodiment, as shown in FIG. 6, the panel speaker F includes a vibrating panel 15
and a vibrating element 18.
The panel speaker F doubles as the output of the incoming call and the output of the voice of the
other party.
The panel speaker F is configured as a part of the screen 3.
That is, the screen 3 also has the function of the panel speaker F.
[0020]
The preferred embodiment of the present invention has been described above, but the present
embodiment has the following features.
[0021]
The straight type mobile telephone 1 includes a housing 2 and a microphone 8 housed in the
housing 2 for inputting voice.

straight type mobile telephone 1 further includes a removable waterproof cap 10 for opening or
closing the opening 9. According to the above configuration, the straight type mobile phone 1
can be used safely in the sea or in the river. That is, the straight type mobile phone 1 can be said
to be a seawater-resistant sandproof type mobile phone usable in the sea or a river, and the
usage scene of the straight type mobile phone 1 can be effectively expanded.
[0022]
The straight type mobile telephone 1 further includes a panel speaker F. The panel speaker F is
elastically supported by the housing 2 and includes a vibrating panel 15 capable of generating a
sound wave, and a vibrating element 18 mounted on and bonded to the vibrating panel 15 to
convert an electrical sound signal into acoustic vibration. Have. According to the above
configuration, it is possible to exhibit the same waterproof performance as the waterproof
speaker.
