Description

  The present invention relates to a portable terminal device in which a main body vibrates when notification of an incoming call or the like is performed.

In a mobile terminal device such as a mobile phone terminal, a notification when there is an incoming call or the like is usually performed using sound or displaying on a screen or a lamp.
In many cases, when a so-called manner mode or the like is used, an incoming call or the like can be notified by vibration (for example, Patent Document 1).

JP 2009-159527 A

However, in the sound notification, the user may not notice the notification when the surrounding noise is large.

The vibrator holding portion 107 is provided with a hole 107a into which the shaft portion 106b is fitted.

The vibrator 108 is a vibration unit that vibrates under the control of a control unit (not shown) when an incoming call is notified. As the vibrator 108, for example, a bimorph vibrator in which piezoelectric elements are stacked can be used. The vibrator 108 is provided with a vibration transmitting portion 108a and a support end portion 108b.
The vibration transmission unit 108 a is provided in the vicinity of one end of the vibrator 108 and is applied to the shaft end 106 c of the second casing 106. The vibration transmission unit 108 a transmits the vibration of the vibrator 108 to the second housing 106.

In the present embodiment, the pitch P1 is made shorter than the pitch P2 by disposing the number of the first protrusions 111 one more than the number of the second protrusions 112.

  When there is an incoming call with the mobile terminal device 100 placed on the table T or the like as shown in FIG. 3, the control unit (not shown) starts the vibration of the vibrator 108. When the vibrator 108 vibrates, vibration is transmitted from the vibration transmission unit 108a to the second housing 106, and the second housing 106 vibrates along the axial direction of the shaft portion 106b. Due to the vibration of the second casing 106, the first protrusion 111 and the second protrusion 112 repeat approach and separation. At this time, the slope 111a of the first protrusion 111 and the slope 112a of the second protrusion 112 are provided so as to face each other. Therefore, the first casing 105 and the second casing 106 are provided. A relative rotational movement can occur between the two. Further, the interval between the first protrusions 111 arranged in the circumferential direction (pitch P1) and the interval between the second protrusions 112 arranged in the circumferential direction (pitch P2) are different from each other. The relative rotational movement with respect to the second housing 106 can be further ensured.

  When the first casing 105 and the second casing 106 relatively rotate, the mobile terminal device 100 placed on the table T has the first casing 105 placed on the table T. Rotate against. Therefore, the user can recognize the notification of an incoming call or the like by visually recognizing the rotation of the mobile terminal device 100. Further, when the user holds the mobile terminal device 100 in his hand or puts it in a pocket of clothes, the user can feel the vibration and recognize the incoming call as before.

  As described above, according to the first embodiment, the mobile terminal device 100 placed on the table T or the like can rotate the first housing 105 at the time of incoming call notification or the like. Therefore, even in a state where the mobile terminal device 100 is placed on a table or the like in an environment where the surrounding noise is large, various notifications such as an incoming call notification can be easily noticed by the user.

The material of the hair-like body 211 may be a metal, a resin, or other materials as long as the elastic deformation is possible. Further, as described above, the hair bodies 211 are arranged side by side in the circumferential direction on the surface on the back surface side of the vibrator holding unit 107, and are provided to be inclined in the same direction in the circumferential direction. .

In the mobile terminal device 200 of the second embodiment, when the vibrator 108 vibrates, the vibration is transmitted from the vibration transmitting unit 108a to the second housing 206, and the second housing 206 is along the axial direction of the shaft portion 206b. Vibrate. The hair 211 is repeatedly elastically deformed by the vibration of the second casing 206. At this time, the action of the frictional force at the portion where the tip of the hairy body 211 is in contact with the second housing 206 is when the hairy body 211 is elastically deformed and when it is restored. It is different. Therefore, the mobile terminal device 200 can cause a relative rotational movement between the first housing 105 and the second housing 206.
