DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, and more particularly to a mobile phone having a function of notifying a user of an incoming call by vibration.

[0002]

2. Description of the Related Art Conventionally, it is well known that a radio paging apparatus has a built-in vibrator and propagates its vibration to a housing to notify a user of an incoming call to a telephone. this is,
This is for notifying only the person himself / herself of the incoming call so as not to disturb the surroundings during a meeting or in an environment such as inside a crowded train.

[0003] However, a portable telephone has not yet been developed which uses a vibrator to notify incoming calls.

[0004]

In recent years, portable telephones have been reduced in size and weight, but in reality, they are still considerably larger in volume and weight than wireless paging devices.

[0005] In order to vibrate the housing of the portable telephone which cannot be sufficiently reduced in size and to allow the user to recognize the incoming call,
A considerably large vibrator is required, and the driving power becomes large.

Also, unlike a radio paging apparatus, a mobile phone needs to perform not only reception but also transmission, and sends out control data and line connection confirmation data even while a paging signal is being received, that is, while a vibrator is being driven. A wireless transceiver is provided. Data handled by the wireless transceiver generally has a small frequency shift and is easily affected by vibration.

As described above, the conventional mobile phone requires a large vibrator and a power source for driving the large vibrator, for example, a battery having a large capacity. Further, the vibration of the housing is affected by the performance of the wireless transceiver. There is a problem that it is difficult to employ a vibrator in a mobile phone because it has an adverse effect.

An object of the present invention is to provide a portable telephone which is miniaturized by using a foldable housing and which minimizes the propagation of vibration of a vibrator to a radio transceiver.

[0009]

A portable telephone according to the present invention comprises a first and a second partial housing which are foldably connected by a hinge, wherein the first partial housing is at least wireless. A transceiver is accommodated, and the second partial housing houses a vibrator that is activated at least by an incoming signal and vibrates a wall surface of the second partial housing.

[0010] Further, a shock absorbing member is added to the hinge portion to reduce the propagation of vibration of the wall surface of the second partial housing to the first partial housing.

[0011]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a portable telephone according to the present invention. FIG. 1 (a) shows a state during a telephone call, and FIG. 1 (b) shows a state waiting for an incoming call.

As shown in FIG. 1, the portable telephone of this embodiment comprises a first partial housing 2 and a second partial housing 3 which are foldably connected by a hinge 1.

The first partial housing 2 has an antenna 4
, A radio transceiver 5 and a speaker 6, and a vibrator 7 and a microphone 8 are accommodated in the second partial housing 3.

That is, a relatively small and lightweight microphone 8 is mounted in a second housing separate from the first partial housing 2 containing the wireless transceiver 5 and the speaker 6 having the largest volume and weight.
When talking, the speaker 6 and the microphone 8 are opened to the state shown in FIG.
Be near your mouth.

In this embodiment thus constructed, the second partial housing 3 is smaller than the first partial housing 2, the built-in vibrator 7 can be small, and the driving power supply (battery) capacity is also small. A small one is fine.

The hinge portion 1 is essentially a movable portion, and the vibrator 7 is attached so that when driven (when an incoming call is received), its vibration is transmitted to the wall surface of the second partial housing 3. I have.

The second partial housing 3 is provided with a hinge 1
1B, and when folded as shown in FIG. 1 (b), it comes into contact with the first partial housing 2 via the buffer member 10, so that it is transmitted to the first partial housing 2 at the time of an incoming call. The vibration of the vibrator 7 is greatly attenuated, and hardly adversely affects the characteristics of the wireless transceiver 5.

[0019]

As described above, the portable telephone of the present invention has a foldable structure and has two vibrators.
Since the two sub-housings are accommodated in the sub-housing that can be reduced in both volume and mass, the user can recognize the incoming call with a small vibrator.

Therefore, the capacity of the power supply for driving the vibrator can be reduced, and the user can be notified of the incoming call by the vibrator while the portable telephone is kept compact.

Further, since the vibrator is housed in a partial housing separate from the radio transceiver, there is an effect that the influence of the vibration on the characteristics of the radio transceiver is extremely small.
