Electronic device
[0001]
The present invention relates to an electronic device provided with an acoustic component.
[0002]
Conventionally, in a portable terminal device such as a portable telephone or a PDA (Personal
Digital Assistant), a music player, a personal computer, a portable television, a digital camera, a
radio receiver, an electronic notebook, and the like, a speaker, a microphone, a receiver, etc.
Acoustic components are placed.
[0003]
However, with the recent demand for miniaturization and high performance of electronic devices,
the space for arranging the acoustic components is limited, and the acoustic components may be
arranged at positions which are not preferable for the sound quality characteristics such as the

back of the device.
[0004]
Therefore, various techniques for reflecting the sound from the acoustic component disposed on
the back surface or the like of the electronic device to the front side of the electronic device are
disclosed (for example, see Patent Documents 1 to 3).

respect to the housing 3, for example, by setting the housing-side hinge portion 4 a to be an
eccentric hinge having an eccentric shaft, the angle thereof To resist rotation so as to be held by
Similarly, when the second plate 4c is rotated to a predetermined angle with respect to the first
plate 4b, the plate hinge 4d may also be configured to resist rotation so as to be held at that
angle.
The same applies to the main body hinge portion 3 c of the housing 3.
[0022]
The reflection support member 4 at the reflection support position (P2) reflects the sound S
emitted obliquely downward from the acoustic component 2 obliquely downward by the first
plate 4b, and the reflected sound S is reflected by the second plate 4c. Reflect obliquely upward.

In the present embodiment, the reflection support member 4 is located in the same plane as the
acoustic component 2 in the housing 3 at the housing position (P1). Therefore, since the
reflective support member 4 in the accommodation position (P1) is disposed around the acoustic
component 2, the electronic device 1 can be simplified.
[0027]
In the present embodiment, the reflection support member 4 is formed with through holes 4e
and 4f communicating with the acoustic component 2 at the accommodation position (P1).

positioned at the storage position (P1).
[0028]
In the present embodiment, the output signal is transmitted to the user by reflecting the output
signal emitted from the speaker 2, for example, the sound S, in substantially the same direction
as the display direction (arrow D) of the display unit 5 by the reflective support member 4. It can
be made easy.
[0029]
In the present embodiment, the acoustic component 2 is described as a speaker that emits an
output signal, for example, voice S, but it is also possible to use a microphone, receiver or the like
to which an input signal, for example, voice is input. .
In that case, the reflective support member 4 reflects the input signal from the outside to the
acoustic component 2.
[0030]
In the present embodiment, an example has been described in which the acoustic component 2 is
located on the back of the housing 3 on the opposite side of the display unit 5. However, the
arrangement space of the acoustic component 2 is, for example, electronic when the acoustic
component 2 is used It may be the bottom and top or side of the device 1 and is not limited to
the back.
[0031]

the main body hinge portion 3c has been described as an example, but the case 3 may be a nonfoldable one.
In the present embodiment, the first plate 4b and the second plate 4c are connected by the plate
hinge 4d, and the reflection support member 4 is foldable. However, the reflection support
member 4 is foldable. Alternatively, for example, if the reflective support member 4 is made

8
rotatable relative to the housing 3, the housing 3 can be supported.
[0032]
In the present embodiment, the reflection supporting member 4 in the housing position (P1) is
located on the same plane as the acoustic component 2 in the housing 3, so that the electronic
device 1 can be made compact. However, in the housing position (P1) The reflective support
member 4 may be located on a surface different from the acoustic component 2. Furthermore,
the reflective support member 4 may be disposed on the same plane as the acoustic component
2 and at a position not covering the acoustic component 2 at the accommodation position (P1).
[0033]
In the present embodiment, since all of the first plate 4b and the second plate 4c at the
accommodation position (P1) are accommodated in the housing 3, the reflection supporting
member 4 can be made extremely compact. If at least a part of the first plate 4 b and the second
plate 4 c is accommodated, it is possible to make the reflective support member 4 compact.
[0034]
In the present embodiment, an example has been described in which the sound S emitted from
the acoustic component 2 is reflected by the reflective support member 4 in the same direction
as the display direction (arrow D) of the display unit 5. Even if the display direction (arrow D) of
the unit 5 is not completely the same, for example, it is possible to easily transmit the sound S to
the user who looks at the display unit 5, the reflection direction of the sound S by the reflection
support member 4 is It is not limited to the display direction (arrow D) of the display unit 5.
[0035]
In the present embodiment, the electronic device 1 is described as, for example, a mobile phone.
However, the electronic device may be any device provided with an acoustic component such as
a speaker, a microphone, or a receiver. For example, PDA (Personal Digital Assistant) Other
electronic devices, such as music players, personal computers, portable televisions, digital
cameras, radio receivers, electronic organizers, etc. may be used.
