Description

Description: TECHNICAL FIELD The present invention relates to a portable wireless telephone device, and more particularly to a portable wireless telephone device and a portable wireless telephone device for notifying a user of a need for operation with a notification sound. Regarding display device.

[Conventional technology]

In general, since the portable wireless telephone device is large enough to be held and operated with one hand, it is often carried in a bag, a briefcase, a handbag, or the like when not in a call. Here, since there is no limitation on the type of means for storing these, it will be simply referred to as a bag. There are various materials such as metal, synthetic resin, leather, and fiber for the bag. Except for the metal, the attenuation of radio waves is small, and it is possible to receive an incoming call while it is stored in the bag. However,
Due to the structure of the bag, sound waves are greatly attenuated, and the sound pressure of the sound generated in the bag is considerably reduced outside the bag and at a position away from the bag. Especially, in an open space where the level of urban driving noise is high, it is very likely that the user will not notice this even if a notification sound sounds in the bag when an incoming call arrives.

[Problems to be solved by the invention]

As described above, the conventional portable wireless telephone device can be stored in the bag and carried, and although it can be received in that state, the notification sound may not be heard by the user.
There was a major drawback that limited the original convenience of the device.

An easy way to compensate for this drawback is to pull out a signal line from the radiotelephone unit that emits a notification sound, lead it out of the bag and make a sound with a sounding body, or blink a light source. A method of informing the user can be considered. However, in this method, the signal line must be attached / detached every time the telephone device is inserted / removed in / from the bag, some plug is required to take out the signal, and the signal line may be added depending on the type of the bag. It is not a wise method because there are some things that are difficult to derive outside of.

On the other hand, a method of attaching a sounding body to the bag by modifying the bag or using a bag dedicated to carrying a mobile phone device and connecting signal lines inside the bag can be considered. Originally, however, the shape and design of the bag are those that are purchased according to the tastes and hobbies of the owner, and it is not appropriate to add modifications or force a special bag. .

[Means for solving problems]

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

〔Example〕

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

FIG. 1 shows the basic configuration of the portable wireless telephone device of the present invention. In the figure, 1 is a radiotelephone main body including a sounding body 3 that generates a notification sound, 2 is a separate unit from the radiotelephone main body, and is a display for detecting a notification sound from the sounding body 3 and notifying the user It is a device. Reference numeral 4 is a bag accommodating the main body 1 of the wireless telephone device, and 5 is a battery unit.

As a means for realizing the basic configuration shown in FIG. 1, a concrete embodiment is shown in FIG.

FIG. 2 shows an example of a specific configuration of the display device 2. The display device 2 is driven by a battery 6. Reference numeral 7 is a microphone for converting the notification sound generated from the radio telephone main body 1 into an electric signal, 8 is a band filter for selectively passing only the frequency of the notification sound, and 9 is an amplifier. Reference numeral 10 is a comparator that outputs only when the amplified notification sound component exceeds a certain value. Furthermore, 11 indicates that the notification sound is being generated from the wireless telephone device body in the bag accurately such that the state with the output of the comparator 10 continues for a certain period of time or repeated at a preset cycle. In the judgment circuit,
It is designed to prevent malfunctions due to notification sound components accidentally generated from other sound sources. The comparator 10 also has a characteristic that it does not operate when a notification sound level above a certain level is detected. This prevents the sounding body 3 and the display device 2 of the radiotelephone body from producing a notification sound when the radiotelephone body is outside the bag and near the bag. It is possible to prevent erroneous detection of an incoming call to another person when the person is near another person who owns the wireless telephone device.

The notification sound thus detected activates the signal source 12 in the example of FIG. 2 to generate a new notification signal.
This notification signal is amplified by the amplifier 13 and becomes a sound from the speaker 14 to notify the user. Although the microphone 7 and the speaker 14 are shown separately in FIG. 2, a dynamic speaker or the like can also be used as a microphone. Therefore, for example, the microphone is usually used as a microphone for detecting a notification sound and operates as a speaker after the detection is completed. You can also let it.

FIG. 3 and FIG. 4 show the actual use state of this device. As described above, the wireless telephone device body 1 emits a notification sound in the bag 4 when there is an incoming call, but the sound pressure is very low when the distance from the surface of the bag 4 to the user's ear is about 1 m or more. However,
On the surface of the bag 4 itself or in the vicinity of the surface, there is a sound pressure that can be clearly distinguished from ambient noise. The degree depends on the degree of sealing and the material of the bag 4, but it is conceivable that the microphone 7 (see FIG. 2) of the display device 2 is closely attached to the bag 4 in order to ensure the detection of the notification sound. .

FIG. 5 shows the microphone 7 of the display device 2 from the above viewpoint.
This is an example in which the is attached to the outer surface of the bag 4. That is, the microphone 7 is in close contact with the bag by the suction plate 15. Further, although the adhesive tape 16 is used to fix the display device 2 in FIG. 5, if the sound pressure attenuation by the bag 4 is small, it is sufficient to simply hang it on the bag 4 as shown in FIG. . Further, as shown in FIG. 6, only the microphone 7 that needs to be in close contact with the bag 4 may be led out from the display device 2 and adhered with an adhesive tape or the like.

By the way, although it has been described above that the user is informed of the result of detecting the notification sound, the display device 2 emits the sound again. However, a method of lighting or blinking the lamp or displaying characters on the display board is described. The method may be used, and it is effective to use them together. Further, the notification sound generated from the main body of the wireless telephone device can be used not only for informing the incoming call but also for various purposes for prompting the user to operate. For example, by providing a device for detecting a drop in the battery voltage and storing the battery in the bag, when the voltage of the battery drops and it becomes necessary to charge the battery or replace the battery, the sounding body is made to sound to the user. We can inform you of that. At this time, a notification sound that can be distinguished from a notification sound that sounds when a normal incoming call is made, for example, a notification sound having a different frequency, and the display device 20 side includes the band filter 8 to the amplifier 13.
By preparing the group, it is possible to distinguish which state has occurred. Furthermore, a plurality of frequencies of the notification sound are prepared, a string of numbers or characters is sent according to the combination of frequencies or the length of interruption, and the judgment circuit 11 of the display device deciphers this to provide the user with necessary information. You can also inform them.

FIG. 7 shows an embodiment in this case. In the main body 1 of the wireless telephone device, 17 is a sound source of different n kinds of frequencies, 18 is a signal selection / synthesis circuit, 19 is a modulation circuit for signal interruption, and 20 is an amplifier. On the other hand, the display device 2 also uses sound display,
The user knows that there is some information from the sound generated by the speaker 14, and knows the contents by the display 21. n bandpass filters 22 corresponding to n sound sources 17 and n comparators
The notification sound detected in 23 is judged and decoded by the control circuit 24,
The speaker 14 is turned on and the contents are displayed on the display 21.

By providing such a function, it can be used for various purposes as well as the telephone number of the calling side and the message for battery replacement. In addition, if the wireless telephone device body 1 has a built-in clock, it may be stored in case that a specific number needs to be called at a certain time, and a communication tone is sounded at that time to display the display device. It can also be applied to notify the user from. Further, by deciding a specific identification code between the main body of the wireless telephone device and the display device, it is possible to almost completely prevent malfunction when a device of the same type owned by another person is nearby. Although the embodiment having the structure as described with reference to FIG. 7 is complicated, all the circuits are easy to be integrated, and there is no problem in reducing the price and the size.

〔The invention's effect〕

INDUSTRIAL APPLICABILITY As described above, the present invention is a very effective device for surely notifying the user of an incoming call or the necessity of battery replacement even when the portable radio telephone device is housed in a place where acoustic attenuation is large. I will provide a. Since the wireless telephone device main body and the display device are only acoustically coupled, it is not necessary to attach or detach the signal line to the wireless telephone device main body or to perform any processing on the bag to be stored. In addition, the mobile wireless phone rings,
Generates notification sound of different frequency depending on the type of alarm sound,
Since the display device is configured to generate and display the notification sound of different frequencies separately, the user can accurately understand the state of the wireless telephone body depending on the type of the notification sound. Is. Furthermore, it is possible to avoid a malfunction due to mixing noise of other frequencies.

Thus, by adding the display device described in the present invention, the present invention is a conventional device of the same type in that the functions possessed by the main body of the portable radiotelephone device can be utilized without being damaged even when the bag is housed. Great compared to.
