Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a portable radio telephone device, and more particularly to a portable radio telephone device that notifies the user of the need for operation through a notification sound.

Since it is small enough to be operated, it is often carried around in a bag, briefcase, or handbag when not in use. Here, since the type of storage means does not matter, it will simply be referred to as a bag. The material of the bag is metal.

There are a variety of materials such as synthetic resin, leather, and textiles.

Among these, except for gold, the amount of attenuation of radio waves is small.

You can receive calls while keeping it in your bag. However, due to the structure of the bag, the attenuation of sound waves is large, and the sound pressure of the sound generated inside the bag decreases considerably at a position outside the bag and further away from the bag. Particularly, in an open space where the urban noise level is high, it can be very helpful if the user does not notice even if a call is received and the notification tone sounds in the bag.

[Problem that the invention seeks to solve]

As mentioned above, although conventional mobile radio telephone devices can be carried in a bag and can be received while in that state, the user may not be able to hear the first call tone.9.
There were major drawbacks that limited the usefulness of the device.

An easy way to compensate for this shortcoming is to pull out the signal line from the main body of the radio telephone device that emits the notification tone, lead the signal line outside the bag, and use the sounding body to make the sound or flash the light source. I can think of a way to notify the user. however.

In this method, the signal line must be connected and disconnected every time the telephone device is put in or taken out of a bag.

Some kind of connector is required to extract the signal.

Furthermore, depending on the type of bag, it may be difficult to lead the signal line outside the bag, so this is not a wise method.

On the other hand, it is also possible to modify the bag or use a bag specifically designed to carry the mobile phone, attach a sounding body to the bag, and connect the signal line inside the bag. However, originally, the shape and design of a bag should match the tastes and hobbies of the owner, and it is inappropriate to force a bag to be modified or specially designed. I can't say that.

[Means for solving problems]

The present invention has been accomplished in order to eliminate the drawbacks of conventional portable radio telephone devices as described above.

The portable radio telephone device according to the present invention includes a main body of the radio telephone device having a device that notifies the user of the need to operate the radio telephone device by means of a notification sound, and a device that notifies the user of the need to operate the radio telephone device, and a device that produces the notification sound separately from the main body of the radio telephone device. and a display device that detects the detection results and informs the user of the detection results.

In this way, even when the wireless telephone device is stored in a bag or the like, if there is an incoming call, for example, a notification sound is emitted from the display device installed outside the bag, and the user is prompted to operate the device. Make it known that there is a need.

〔Example〕

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

FIG. 1 shows the basic configuration of a portable radio telephone device according to the present invention. In the figure, 1 is a sounding body 3 that generates a notification sound.
The main body of the wireless telephone device including.

Reference numeral 2 denotes a display device 5 which is installed separately from the main body of the radio telephone device and is used to detect the notification sound from the sound generator 6 and notify the user. Reference numeral 4 indicates a bag that houses the radio telephone device main body 1, and 5 indicates a battery section.

As a means to realize the basic configuration shown in FIG.

A specific example is shown in FIG. 2 and below.

FIG. 2 shows an example of a specific configuration of the display device 2. As shown in FIG. The display device 2 is powered by a battery 6. Reference numeral 7 denotes a microphone that converts the notification sound generated from the wireless telephone device body 1 into an electrical signal.

8 is a bandpass filter that selectively passes only the frequency of the notification sound, and 9 is an amplifier. This is a comparator that outputs an output only when the component of the notification sound amplified by 10u exceeds a certain value. Furthermore, 11 indicates that the output of the comparator 10 continues for a certain period of time or a notification sound is generated from the main body of the wireless telephone device in the bag, such as repeating at a preset period. This is a circuit that determines whether a device is present or not, and is designed to prevent malfunctions due to notification sound components accidentally generated from other sound sources. Comparator 10 also. It has a characteristic that it does not operate even when a notification sound level above a certain level is detected. This makes it possible to use a wireless phone when the main body of the wireless telephone device is outside the bag and close to the bag.

A notification sound is prevented from being emitted by both the sounding body 3 and the display device 20 of the main body of the radio telephone device when another person who owns the same type of radio telephone device is nearby.

It is possible to prevent erroneously detecting an incoming call to another person.

Now, what is the notification sound detected in this way?

In the example of FIG. 2, the signal source 12 is activated to generate a new notification signal. This notification signal is amplified by an amplifier 13,
A sound is emitted from the speaker 14 to notify the user. In Figure 2, microphone 7 and speaker 14 are shown separately.
Although it is.

Since a dynamic speaker or the like can also be used as a microphone, for example, it can normally be used as a microphone for detecting a notification sound, and after the detection is completed, it can be operated as a speaker.

FIGS. 3 and 4 show the actual usage of the device. As mentioned above, the radio telephone device main body 1 makes a notification sound in the bag 4 when there is an incoming call.

If the distance from the surface of the bag 4 to the user's ears is about 1 m or more, the sound pressure will be very low. However, on the surface of the bag 4 itself or very close to the surface, there is a level of sound pressure that can be clearly distinguished from surrounding noise. The degree of this will vary depending on the degree of sealing and the material of the bag 4, but in order to ensure the detection of the 1st notification sound, it is considered that the display device 2, especially the microphone 7 (see Figure 2), should be brought into close contact with the bag 4. nru.

FIG. 5 shows the microphone 7 of the display device 2 from the above point of view.
In this example, the bag 4 is brought into close contact with the outer surface of the bag 4. That is, microphone 7i11. It is closely attached to the bag by the suction plate 15. Also, in FIG. 5, adhesive tape 16 is used to fix the display device 2, but if the attenuation of the sound pressure by the bag 4 is small, it can be simply hung from the bag 4 as shown in FIG. That's fine. Furthermore, as shown in FIG.

Only the microphone 7 that needs to be brought into close contact with the bag 4 may be led out from the display device 2 and brought into close contact with the bag 4 using adhesive tape or the like.

By the way, so far we have explained that the 1 display device 2 sounds again as a means of notifying the user of the result of detecting the 1 notification sound. It is also effective to use these methods in combination. Further, the notification sound generated from the main body of the wireless telephone device can be used not only to notify the user of an incoming call, but also for various purposes to prompt the user to perform operations. For example, by installing a device that detects a drop in battery voltage and configuring a sounding device to sound when the battery voltage drops while stored in a bag and the battery needs to be charged or replaced, the user can You can let them know. At this time, it is possible to distinguish which state has occurred by making the notification sound different from the notification sound that is normally made when receiving a call. moreover.

A plurality of notification sound frequencies are prepared, and a string of numbers and letters is sent based on the combination of nine frequencies and the length of the interruption, and the judgment circuit 11 of the display device decodes this number.

It may also be necessary to notify the user of necessary information.

FIG. 7 shows an embodiment in this case. In the wireless telephone device main body 1, 17 is a sound source of n different frequencies;
8 is a signal selection synthesis circuit.

19 is a modulation circuit for signal intermittent, and 20 is an amplifier. On the other hand, 1 display device 2 uses both sound and display, and a speaker 14
The user knows from the sound generated that there is some information 9
The contents can be known from the display 21. n bandpass filters 22 and n comparators 26 corresponding to n sound sources 17
The notification sound detected by is judged and decoded by the control circuit 24,
The speaker 14 sounds and the content is displayed on the display 21.

By providing such a function, it can be used not only for sending a telephone number of a calling party or a message for battery replacement, but also for various other purposes. In addition.

If the wireless telephone device body 1 has a built-in clock.

If it is necessary to make a call to a specific number at a certain time, n may be stored in memory, and the display device may notify the user by playing a passing tone at that time. Also,
By predetermining a specific identification code between the wireless telephone device main body and the display device, malfunctions can be almost completely prevented when a device of the same type owned by another person is nearby. Although the embodiment of the configuration described in FIG. 7 is complicated, all of the circuits are easy to integrate into integrated circuits, so there is no problem in reducing the cost and size.

〔Effect of the invention〕

As explained above, the present invention is very effective in notifying the user of an incoming call or the need to replace the battery even when the mobile radio telephone device is housed in a place with large acoustic attenuation. Provide equipment. Since the main body of the radio telephone device and the display device are only acoustically coupled, there is no need to perform any processing on the signal line to be attached to or removed from the main body of the radio telephone device or on the bag in which it is stored. In addition, by devising the signal system for the 9-9 notification sound, it is possible to inform the user of more detailed information and to avoid malfunctions.

In this way, by adding the display device described in the present invention, the present invention is superior to conventional similar devices in that it can be used without any loss even when housed in the original functional separation of the mobile radio telephone device. It's much better.
