Abstract

PROBLEM TO BE SOLVED: To release external force exerted to the portable telephone set and to obviate defects by delivering a variable voltage signal to a control means, in response to the strength of the external force and driving a notice means, if the voltage signal is at the outside of a specified value set arbitrarily in advance by the control means to notify the user about the occurrence of deformation resulting from the exerted external force. SOLUTION: A projection section 8 is projected in the form of contact with a surface of a pressure-sensing element 1. A projection section 9 is projected from a case 6 on the other side of a printed circuit board 7 to which the pressure-sensing element 1 is connected, and the projection sections are placed to clamp the pressure-sensing element 1 inbetween. When an external force is exerted on the case 6, the projection section 8 of the case 6 receives the external force to press against the pressure-sensing element 1. The pressure-sensing element 1 delivers a voltage signal to a control section in response to the strength of pressing, that is, the magnitude of the external force, the control section compares the voltage signal with a value arbitrarily preset arbitrarily to control a notice section, which notifies the user to the effect that the portable telephone set received external pressure higher than the value set. Thus, defects of the portable telephone set due to the external pressure are surely prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone,
In particular, the present invention relates to a mobile phone having a function of notifying that a housing has been subjected to external force or deformed.

[0002]

2. Description of the Related Art Conventionally, in a portable telephone, for example, as disclosed in Japanese Patent Application Laid-Open No. 3-235533, a control means including a function of notifying that a casing has been deformed by an external pressure has been proposed. .

[0003]

However, in the prior art, when the housing receives an external pressure and the external pressure is applied beyond a specified force, the elastic conductor conducts mechanically. The detection setting is difficult, and there is a problem that the detection means malfunctions with a small external pressure, or the detection cannot be made in time if a sudden pressure is applied, and the parts of the mobile phone are damaged.

An object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a mobile phone capable of releasing an external force and preventing a failure in advance by notifying the pressure detecting means of the external force without malfunction.

[0005]

A portable telephone according to the present invention comprises:
When a control unit drives a notifying unit to notify a call upon receiving a wireless calling signal, a pressure detecting unit provided inside the housing responds to the strength of the external force when an external force is applied to the housing. Then, a variable voltage signal is transmitted to the control unit, and the voltage signal is compared with a predetermined value arbitrarily set by the control unit. If the voltage signal is outside the specified value, the notification unit is driven to reduce the external force. This is a configuration having a function of notifying that deformation has occurred.

[0006] Thus, by changing the driving method of the notification means according to the amount of external force, the notification can be gradually performed. In addition, by setting the specified value for each mobile phone, the variation can be suppressed.

Further, the control means measures the amount of change in the voltage signal which varies in accordance with the strength of the external force, so that the notifying means can be quickly driven and notified of a sudden external force. It is possible.

The portable telephone according to the present invention is provided with a notification means different from the above when the portable telephone is lightly grasped.
For example, a function that allows a call to be made simply by squeezing lightly when receiving a call becomes possible.

[0009] Further, when an external force is applied to the mobile phone for a long period of time, if the mobile phone is in a communicable state, the mobile phone can talk to a preset telephone number and emit an alarm sound to notify the user. It is.

[0010]

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

FIG. 1 is a block diagram of one embodiment of the present invention. The output of the pressure detecting element 1 provided in the mobile phone 5 is connected to the control unit 2. The control unit 2 includes a mobile phone 5
Is received from the receiving unit 3 and the notification unit 4 is controlled to perform notification. Similarly, when a voltage signal corresponding to the amount of external force is input from the pressure detecting element 1, the control unit 2 determines the voltage signal and controls the notification unit 4 to perform notification.

Next, the operation will be described.

FIG. 2 is a sectional view of one embodiment of the present invention.

The pressure detecting element 1 is electrically connected to a printed circuit board 7. A protrusion 8 protrudes from the housing 6 in contact with the surface of the pressure detection element 1. On the opposite side of the printed wiring board 7 to which the pressure detecting element 1 is connected, a protruding portion 9 protrudes from the housing 6 and is arranged so as to sandwich the pressure detecting element 1.

FIGS. 3 and 4 are cross-sectional views for explaining a state where the housing 6 is deformed by an external force.

FIG. 3 shows a deformed state when an external force is applied from A. In this case, the projection 8 of the housing 6 receives an external force and presses the pressure detection element 1. A voltage signal is transmitted from the pressure detecting element 1 to the control unit 2 in accordance with the strength of the crimping, that is, the magnitude of the external force, and is compared with a value arbitrarily set in advance by the control unit 2 to control the notification unit 4. A notification is made to inform the user that the mobile phone 5 has received an external pressure higher than the set value.
Thereby, breakage of the mobile phone 5 due to external pressure can be reliably prevented.

In FIG. 4, except that the protruding portion 9 of the housing 6 pushes the printed wiring board 7 to which the pressure detecting element 1 is fixed by receiving an external force from B, and the pressure detecting element 1 is crimped by the protruding portion 8. The description is omitted because it is the same as the description of FIG.

Further, even if the pressure detecting elements 1 are electrically connected to both sides of the printed wiring board 7, the same effects as in the above-described embodiment can be obtained.

[0019]

As described above, the present invention provides a pressure detecting element which receives an external force from a part of a housing and outputs a variable voltage signal in accordance with the amount of external force.
This has the effect of notifying the user of the deformation of the housing due to external pressure without malfunction, and preventing damage to the mobile phone.
