However, since the conventional portable terminal is provided with the LEDs 104 and 105 on the front side and the back side of the terminal body 100, it is necessary to provide a plurality (two) of LEDs.
In addition, since the conventional portable terminal arranges the speaker 103 and the front LED 104 individually above the display unit 101, it is necessary to secure a large area for providing the speaker 103 and the front LED 104. This hinders the terminal body 100 from being made compact.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a portable terminal that can reliably recognize an incoming call and can be made compact.

  The portable terminal of the present invention has a sound hole formed on one surface of the housing, a speaker and a light source disposed in the vicinity of the sound hole and inside the housing, and light projected from the light source. A light guide member having an exposed portion exposed to the other surface of the housing and leading to a portion facing the hole, and a sound guide formed by the light guide member for guiding the sound generated from the speaker to the sound hole And a passage.

The light guide member guides light from the light source to the sound hole and to the exposed portion. Therefore, with one light source, light can be emitted from the sound hole on one side of the housing, and light can be emitted from the exposed portion on the other side.
Furthermore, by forming a sound guide path with the light guide member, the sound generated from the speaker is guided to the sound hole.
Therefore, on one side of the housing, when an incoming call is received, both the ringtone and incoming display light are notified, and on the other side, the incoming display light is notified.
Thereby, the user can recognize the incoming call from either side of the housing.

  In addition, since one side of the housing is notified by both the ring tone and the incoming display light when an incoming call is received, it is confirmed that the sound emitted from the sound hole is emitted from the sound hole. The user can be strongly recognized.

  Furthermore, since the light guide member also serves as a sound guide path, and only the light guide member guides light to the surfaces on both sides of the housing, the number of components such as a light source is reduced, and the size can be reduced.

  Moreover, the portable terminal of the present invention is characterized in that the light guide member is provided with a wall portion serving also as the sound guide path at a portion facing the sound hole.

  A sound guide path can be obtained with a simple configuration in which a wall is provided on the light guide member. Therefore, simplification of the shape of the light guide member is achieved.

  According to the present invention, since the light guide member also serves as a sound guide path and the light is guided to the surfaces on both sides of the housing by one light source, the number of parts is reduced and the compactness can be achieved.

According to the mobile terminal 10, the light guide member 37 also serves as the sound guide path 44, and only the light guide member 37 emits light on both sides of the upper housing 14 (that is, one side 24 and the other side 30). Therefore, the number of components such as the LED (light source) 35 can be reduced.
Furthermore, since the sound guide passage 48 can be obtained with a simple configuration in which the wall portion 44 is simply provided in the light guide member 37, the shape of the light guide member 37 can be simplified.

Next, the operation of the mobile terminal 10 will be described mainly based on FIGS.
When a call arrives at the mobile terminal 10, a ring tone 49 is generated from the speaker 34 and light 28 is projected from the LED 35.
The ring tone 49 generated from the speaker 34 is guided to the inner sound hole 27 through the sound guide passage 48, that is, the inclined surface 44 c of the wall 44, and is transmitted from the inner sound hole 27 to the outside of the upper housing cover 22.
Also, the ring tone 49 generated from the speaker 34 is transmitted to the outside of the upper casing outer cover 23 from the outer sound hole 31 (see FIG. 5).

On the other hand, the light 28 projected from the LED 35 is taken into the light guide member 37 from the curved surface 42, guided to the top 44 c of the wall 44, and from the inner sound hole 27 reaching the top 44 c of the upper housing cover 22. Projected outward.
Further, the light 28 introduced from the curved surface 42 into the light guide member 37 and guided to the exposed portion 40 (see FIG. 7) is transmitted from the portion 40 exposed from the external light hole 32 for incoming display light to the upper casing outer cover. 23 is projected outside.

As described above, according to the mobile terminal 10, the sound guide passage 48 is formed by the light guide member 37, thereby guiding the ring tone 49 generated from the speaker 34 to the inner sound hole 27 and to the outer sound hole 31. Lead. With one speaker 34, a ring tone 49 can be generated from the inner sound hole 27 of the upper casing 14, and a ring tone 49 is generated from the outer sound hole 31 of the upper casing 14.
Further, the light guide member 37 guides the light 28 from the LED 35 to the inner sound hole 27 and to the exposed portion 40. One LED 35 can emit light 28 from the inner sound hole 27 of the upper housing 14 and emit light from the exposed portion 40.

Therefore, on one surface 24 side of the upper housing 14, when an incoming call is received, both the ring tone 49 and the incoming display light 28 are notified, and on the other surface 30 side, the incoming sound 49 and the incoming display light 28 are also displayed. And both.
As a result, the user can reliably recognize an incoming call from the surface 24 or 30 on either side of the upper housing 14.

On the one surface 24 side of the upper housing 14, a ring tone 49 is generated from the inner sound hole 27 and an incoming display light 28 is projected from the inner sound hole 27 when receiving a call.
It is possible to make the user of the mobile terminal 10 strongly recognize that the sound 49 is emitted from the inner sound hole 27 by light emission from the inner sound hole 27.
