Abstract

PURPOSE:To miniaturize a foldable casing and also to minimize the vibrations of a vibrator which are transmitted to a radio transceiver. CONSTITUTION:A portable telephone consists of the 1st and 2nd partial casings 2 and 3 which is foldably connected together by a hinge part 1. The casing 2 stores an antenna 4, a radio transceiver 5 and a speaker 6, and the casing 3 stores a vibrator 7 and a microphone 8 respectively. That is, the comparatively compact and light-weight microphone 8 is stored in the casing 3 separately from the casing 2 which stores the transceiver 5 and the speaker 6 which have the large volume and weight. In a speech mode, the telephone is unfolded as shown in (a) so that the speaker 6 and the microphone 8 are set close to the ear and the mouth of a user respectively. Then the casing 3 touches the casing 2 via a buffer member 9 of the part 1 and then via a buffer member 10 when the telephone is folded as shown in (b).

Description

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 vibrating.

[0002]

2. Description of the Related Art Conventionally, in a radio calling device, a method is well known in which a vibrator is built in and its vibration is propagated 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 an incoming call so as not to bother others around him / her in an environment such as a meeting or in a car on a crowded train.

However, there has not yet been developed a mobile phone which notifies an incoming call by a vibrator.

[0004]

In recent years, the size and weight of mobile phones have been reduced, but the reality is that the volume and weight are still considerably larger than those of radio call devices.

In order to make the user recognize the incoming call by vibrating the housing of the mobile phone, which cannot be miniaturized sufficiently,
A considerably large vibrator is required, and its driving power also becomes large.

Further, unlike a radio calling device, a mobile phone needs to perform not only reception but transmission, and control data and line connection confirmation data are transmitted even while receiving a call signal, that is, while driving a vibrator. A wireless transceiver is provided. The data handled by this wireless transceiver generally has a small frequency deviation and is easily affected by vibration.

As described above, the conventional mobile phone requires a large vibrator and needs a power source for driving the vibrator, for example, a battery having a large capacity, and further, the performance of the radio transmitter / receiver is affected by the vibration of the housing. There is a problem that it is difficult to adopt a vibrator in a mobile phone because it has an adverse effect.

It is an object of the present invention to provide a portable telephone which is miniaturized by using a foldable housing and in which vibration of a vibrator is minimized from being propagated to a wireless transceiver.

[0009]

A mobile phone according to the present invention is a mobile phone composed of first and second partial housings which are foldably connected by a hinge portion, wherein the first partial housing is at least wireless. A transmitter / receiver is housed, and the second partial housing contains a vibrator that is activated by at least an incoming signal to vibrate the wall surface of the second partial housing.

Further, the present invention is characterized in that a cushioning member is added to the hinge portion to reduce the propagation of the vibration of the wall surface of the second partial housing to the first partial housing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

1A and 1B are perspective views showing an embodiment of a mobile phone of the present invention. FIG. 1A shows a state during a call, and FIG. 1B shows a state waiting for an incoming call.

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

An antenna 4 is provided on the first partial housing 2.
The wireless transceiver 5 and the speaker 6 are housed, and the second partial housing 3 houses the vibrator 7 and the microphone 8.

That is, a relatively small and lightweight microphone 8 is provided in a second casing other than the first partial casing 2 in which the radio transceiver 5 and the speaker 6 having the largest volume and weight are housed.
1), the speaker 6 and the microphone 8 are opened to the user's ear, respectively.
Try to come near your mouth.

In this embodiment having such a configuration, the second partial housing 3 is smaller than the first partial housing 2, the built-in vibrator 7 is small, and the capacity of the driving power source (battery) is also good. You can use a small one.

Further, the hinge part 1 is essentially a movable part, and the vibrator 7 is attached so that its vibration is propagated to the wall surface of the second partial housing 3 when driven (when a call arrives). There is.

The second partial housing 3 has a hinge portion 1
1 and the first partial housing 2 through the buffer member 10 when folded, as shown in FIG. 1 (b), and are thus propagated to the first partial housing 2 when an incoming call is received. The vibration of the vibrator 7 is greatly attenuated, and the characteristics of the wireless transceiver 5 are hardly adversely affected.

[0019]

As described above, the mobile phone of the present invention has a foldable structure and has a vibrator.
Since it is housed in one of the two sub-casings that can be reduced in volume and mass, the user can recognize the incoming call with a small vibrator.

Therefore, it is possible to reduce the capacity of the power source for driving the vibrator, and it is possible to notify the user of an incoming call by the vibrator while keeping the size of the mobile phone small as a whole.

Further, since the vibrator is housed in a partial housing different from the wireless transceiver, the effect of the vibration on the characteristics of the wireless transceiver is extremely small.
