DESCRIPTION JP2014053827
Abstract: PROBLEM TO BE SOLVED: To provide a sound collector capable of collecting generated
sound in a photographing direction by attenuating surrounding generated sound when
photographing with a tablet terminal. SOLUTION: It is a truncated cone-shaped sound collector 1
configured by a large opening 1a, a small closing part 1d, and a tablet terminal insertion part 1e.
By forming the oblique pyramidal outer surface portion 1 b and the closed portion 1 d with a
sound absorbing material that absorbs and attenuates sound, it is possible to attenuate the
surrounding generated sound. Also, by forming the oblique pyramid inner surface portion 1c
with a reflecting material that reflects sound, the generated sound in the imaging direction
coming from the large opening portion 1a is collected at the central position of the tablet
terminal insertion portion 1e. According to this method, it is possible to attenuate surrounding
sound generation and reliably collect sound generation in the shooting direction. [Selected figure]

Sound collector
[0001]
The present invention relates to a sound collector suitable for video shooting on a tablet terminal.
[0002]
The built-in microphone of the tablet terminal does not have the function of collecting the
generated sound in the shooting direction by attenuating the surrounding generated sound.

BACKGROUND ART A sound collector (see Patent Document 1) for collecting generated sound in
a specific direction to a microphone is widely known.

[0004]
However, it is not possible to incorporate the main body internal microphone of the tablet
terminal into the above-mentioned sound collector.
[0005]
An object of the present invention is to provide a sound collector capable of collecting and
recording generated sound in a shooting direction by attenuating surrounding generated sound
by being attached to a tablet terminal.
[0006]
Attenuating the surrounding noise by constructing the large opening, the small closing part, the
external surface of the truncated cone shaped oblique cone made up of the tablet terminal
insertion part and the closing part with a sound absorbing material that absorbs and attenuates
the sound it can.
Also, by forming the oblique pyramid inner surface portion with a reflective material that reflects
sound, it is possible to collect the generated sound in the imaging direction coming from the
large opening at the central position of the tablet terminal insertion portion.
As a result, the generated sound in the vicinity is attenuated, and the generated sound in the
shooting direction can be collected and recorded.

By mounting the sound collector of the present invention to the microphone unit of the tablet
terminal, it is possible to attenuate the surrounding generated sound and to collect and record
the generated sound in the photographing direction.
In addition, we can attach more strongly with elastic tape with a bag.
[0008]
By attaching the sound collector of the present invention to the tablet terminal, the sound
generated from the rear and around the both sides can be attenuated, and the sound generated in
the photographing direction can be reliably taken.

It is the perspective view which equipped the sound collector of this invention to the tablet
terminal. It is a perspective view of the sound collector which attached the weired expansion tape
according to the present invention.

An embodiment of the present invention will be described below with reference to the drawings.
In FIG. 1, by forming the oblique pyramidal outer surface portion 1 b and the closed portion 1 d
of the sound collector 1 with a sound absorbing material that absorbs and attenuates sound, the
surrounding generated sound is attenuated. By forming the oblique pyramid inner surface
portion 1c with a reflecting material that reflects sound, the generated sound in the imaging
direction coming from the large opening portion 1a is collected at the central position of the
tablet terminal insertion portion 1e. It is a sound collector which inserts a tablet terminal in the
tablet terminal insertion part 1e which exists in a sound collection position, and is pinched-held
by the closing part 1d.

FIG. 2 shows a configuration in which the microphone 2 a of the tablet terminal 2 is disposed at
the center position of the sound collector 1 and the camera 2 b captures an image. FIG. 3 shows
a sound collector provided with a hooked expandable tape 3 that can be attached more strongly
to a tablet terminal.
