By the way, when the portable electronic device is set on the mounted object such as a desk in the manner mode, if the mounting surface on the portable electronic device side is flat, the contact area with the mounted object is large. Thus, even when the vibrator motor is driven, the casing itself may not be vibrated sufficiently.
If the casing cannot be sufficiently vibrated by the vibrator, it becomes difficult to reliably notify the user of an incoming call or the like.

  In view of this, the present invention is intended to provide a portable electronic device in which a casing can be vibrated greatly by a vibrator and can be reliably notified to a user by vibration.

In order to solve the above problems, the present invention employs the following means.
Portable electronic device according to the present invention includes a housing and said at least three support points provided on one surface of the housing, a vibrator that is located outside the region connecting the respective support points in the interior of the housing And one surface of the housing has a substantially rectangular shape, a first support point at the center of one end of the surface of the housing, and a second support point at the center of the other surface of the housing. A third support point is provided at each end of the one surface of the housing, and the vibrator includes the third support point across a line segment connecting the first support point and the second support point. It is arranged on the opposite side.
The vibrator may be disposed on a plane passing through the center of gravity of the portable electronic device and the third support point.
The vibrator is arranged at a position substantially symmetrical to the third support point with the center of gravity as the center.
In addition, the center of gravity of the portable electronic device is located inside a region connecting the support points.

A portable electronic device according to the present invention includes a housing, at least three support points provided on one surface of the housing, and a vibrator disposed outside a region connecting the support points inside the housing.

On the other hand, on the rear surface of the rear case 3, a battery replacement lid 8 is provided in a substantially lower half region so as to be openable and closable, and the rear case 3 is biased toward the left side of the upper end (when viewed from the front of the front case 2). The antenna accommodating portion 9 is formed at a position so as to bulge outward in an arc shape, and the antenna 15 is accommodated in the antenna accommodating portion 9. Note that the rear surface of the rear case 3 is not a completely flat surface but is gently curved in the width direction as shown in FIG. 3, and the center in the width direction is the top of the curved shape.

  As shown in FIG. 6, a circuit board 10 for mounting a plurality of electric / electronic components is mounted inside the housing 1 so as to be sandwiched between the front case 2 and the rear case 3. A battery 11 having a substantially rectangular shape is accommodated near the center of the rear case 3 side. In addition to the circuit board 10 and the battery 11, the housing 1 houses a receiving speaker and a transmitting microphone (both not shown) and a vibrator 12. The reception speaker also functions as a notification speaker.

  The vibrator 12 has a known structure in which a weight is eccentrically attached to the rotating shaft of the motor 12a. The motor 12a is housed and supported in a frame portion on the rear case 3 side, and is connected to a circuit via a spring terminal (not shown). The contact pattern on the back side of the substrate 10 is electrically connected.

  By the way, this mobile phone is placed on the upper surface of the object 13 such as a desk (hereinafter referred to as “the mounting surface 13 a”) as shown in FIG. On the back side of the rear case 3, there are provided three support points 14A, 14B, and 14C that come into contact with the surface 13a when placed on the placement surface 13a. Hereinafter, for convenience of explanation, these are referred to as a first support point 14A, a second support point 14B, and a third support point 14C.

  In FIG. 4, if the side where the antenna 15 of the rear case 3 is arranged is now called the upper side, and the opposite side is called the lower side, the center position in the width direction near the upper side of the rear surface of the rear case 3 is A support protrusion 16 bulging in a substantially arc shape is formed (see FIG. 3). The first support point 14 </ b> A is configured by the top of the support protrusion 16.

  On the other hand, the second support point 14B is constituted by a bulged top portion in the center of the lower side of the rear case 3 in the width direction, and the third support point 14C is formed by the top portion of the antenna housing portion 9 located on one side of the upper side of the rear case 3. It is configured.

  Therefore, in the case of this embodiment, the first support point 14A and the second support point 14B are disposed on the center line o in the width direction of the rear case, and the third support point 14C is disposed in the vicinity of the upper side away from the center line o. Has been. Further, the center-of-gravity position G of the mobile phone is located inside a substantially triangular region a connecting the three support points 14A to 14C and sufficiently close to the center line o.

To such an arrangement of the support points 14A to 14C, the motor 12a of the agitator 12 is positioned to be outside the area a of the substantially triangular in the housing 1, for example, in FIG. 4, the center of gravity position G It is arranged at a position that is substantially symmetrical with the third support point 14C.

  In the above configuration, when the cellular phone is placed on the placement surface 13a with the rear case 3 facing downward, the casing 1 is placed at the three support points 14A to 14C arranged at the respective apexes of the triangle shape. It contacts the surface 13a. At this time, since the center of gravity G of the mobile phone is located inside a substantially triangular area a connecting the support points 14A to 14C, the phone is stably supported on the placement surface 13a.

  When the motor 12a of the vibrator 12 is driven by an incoming call or the like from this state, the vibrator 12 vibrates at a position outside the region a connecting the support points 14A to 14C, so that the vibration tilts the housing 1. Acting as a moment, the support points 14A to 14C strike the mounted surface 13a greatly. Therefore, even if the mobile phone is in the manner mode at this time, it is possible to reliably notify the user of an incoming call or the like.

  In particular, the mobile phone of this embodiment has a plane that passes through the center of gravity position G and the support point 14c among the positions outside the region a connecting the support points 14A to 14C (in this embodiment, the center of gravity position G is the center). Since the vibrator 12 (motor 12a) is disposed at a position substantially symmetrical to the third support point 14C), the third support point 14C is greatly swung up and down around the first and second support points 14A and 14B. A large vibration sound can be emitted between the mounting surface 13a.

  As described above, this cellular phone can vibrate the casing 1 efficiently and greatly by devising the arrangement of the support points 14A to 14C and the vibrator 12, thereby suppressing the output of the motor 12a, thereby reducing current consumption. Reduction can be achieved.

  In addition, this invention is not limited to the said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, a mobile phone having a straight case structure has been described above, but the present invention can also be applied to portable electronic devices having other case structures such as a folding type, a slide type, and a horizontal rotation type. Moreover, in the above embodiment, although the three support points 14A-14C are provided in the housing | casing 1, the number of support points is not restricted to three, and if it is plurality, the number is arbitrary.
