Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone and a PHS terminal.

[0002]

2. Description of the Related Art In a conventional portable device, the reception volume and the reception volume can be fixed to a stable optimum volume by operating a user's own external switch or the like. That is, the sound volume can be appropriately set in consideration of the surrounding situation at the time of use. However, since it did not have a function of enabling a volume setting associated with the act of transmitting itself, the voice volume of the user at the time of transmitting could possibly cause discomfort to the surroundings. Furthermore, even when the volume of the call (sending) is reduced by paying attention to the surroundings when starting to use, it is empirical that the voice may unnecessarily increase when the user is absorbed in the conversation. It is.

[0003] In the case of portable telephone devices that are distributed on the market in an amount exceeding the penetration rate of home telephones, the necessity of improving the manners of calling by users is also important. Note that a mobile phone based on the viewpoint according to Japanese Patent Application Laid-Open No. 10-210117 is disclosed. This mobile phone monitors the user's transmission volume level and informs the user if it is unnecessarily high,
When the volume of the voice is reduced, the reduced volume is compensated by the amplifier, so that a stable volume can be transmitted to the other party.

[0004]

That is, this portable telephone distinguishes the voice of the user from the voice of the surrounding environment by using a numerical ratio between the volume level and the noise level of the surrounding environment during no call. I have. However, although there are restrictions within the range where radio waves can be transmitted and received from the base station,
The fact that it can be used anywhere can play a part in increasing the penetration of mobile phones. Therefore, when the surrounding environment changes drastically due to the action of the user, there is a possibility that the measured value during no-call is not quite stable. Further, particularly when used in a place where the surrounding environment is noisy, the volume level and the noise level may be inverted and recognized, and as a result, voices other than the user's voice may be compensated. There is a risk. For example, a voice, an announcement or a horn of a third party in a busy street or on a train platform.

[0005] The present invention has been made in view of the above points, and it is possible to improve the manners of a mobile phone user and eliminate the danger of amplifying unnecessary sounds.

[0006]

According to a first aspect of the present invention, there is provided an audio signal converting unit which converts an audio signal input to a transmitting unit into a digital signal and obtains a measured value, A first signal holding unit for holding the specified value, a second signal holding unit for holding an arbitrary specified value, and a comparing unit for comparing the measured value with the specified value, wherein the measured value is the specified value And a control unit for transmitting a predetermined signal to a warning sound generating unit or a machine vibration unit when the measured value is less than the specified value.

[0007] According to the portable telephone device of the first aspect of the present invention, when the measured value of the input audio signal converted by the audio signal conversion unit is larger than an arbitrary prescribed value, the user can use a louder voice. It becomes clear that you are typing.
Therefore, the control unit activates the warning sound utterance unit or the body vibration unit, and the warning sound or the vibration of the body warns that the utterance volume of the user is at or above a predetermined level.

[0008] Similarly, when the measured value of the input voice signal is smaller than an arbitrary specified value, the user is not recognized to be making a sufficient utterance. Therefore, when the warning sound generation unit or the body vibration unit is operated by the control unit, the user is alerted that the state is activated by the warning sound or the vibrator function. As described above, the input (speech) volume of the user is monitored, and when the value exceeds the specified value or when the value is less than the specified value, a warning sound or the like is emitted, so that an appropriate voice input is made. Will be able to

According to a second invention of the present application, in the portable telephone device of the first invention of the present application, a user can directly input a prescribed value held in the second signal holding section by key operation. It is characterized by being able to. With this configuration, the user can input a prescribed value arbitrarily, thereby enabling proper use according to the use environment.

According to a third aspect of the present invention, in the first aspect of the present invention, the prescribed value held in the second signal holding unit is a measured value obtained by a user's utterance. It is characterized by that. With this configuration, it is possible to input an appropriate prescribed value depending on the voice quality of the user.

Embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1 FIG. 1 is a block diagram of a mobile phone according to an embodiment of the present invention. FIG. 2 is a block diagram more specifically showing the audio processing unit of FIG. As shown in FIGS. 1 and 2, a user inputs a voice signal by speaking into a microphone 1 connected to a portable terminal. The audio signal input by the microphone 1 is transmitted to the audio processing unit 2. The audio processing unit 2 includes a signal amplification unit 21, an A / D conversion unit 22, a digital signal encoding unit 23, and a comparison unit 3.

The input audio signal is amplified by an amplifier which is a signal amplifier 21 of the audio processor 2 and transmitted to an A / D converter which is an A / D converter 22. The A / D converter converts an input analog audio signal into a digital audio signal. The audio signal converted into the digital signal is transmitted to the digital signal encoding device (CODEC) which is the digital signal encoding unit 23 and the comparing unit 3. A digital signal encoding device (CODEC) encodes a digital audio signal and transmits the digital audio signal to a transmission path.

FIG. 3 is a block diagram showing the comparing section 3 more specifically. The comparing unit 3 is a first holding unit (A register) 31 for holding the converted measured value of the audio signal.
Having. Furthermore, a second holding unit (B) that holds a digitized voice input by the user in an arbitrary state as an initial specified value, or holds a numerical value directly input by a key operation by the user as an initial specified value. Register 32). Further, a detection circuit unit 33 for comparing and detecting the input measurement value held in the first holding unit 31 and the initial specified value held in the second holding unit 32 is provided.

In the detection circuit section 33, the first holding section 3
1 and the data from the A / D converter 22 stored in the second
Is compared with the initial specified value stored in the holding unit 32 of
The result is output to the control unit 5. For example, when the result of the comparison is that the numerical value stored in the first storage unit> the numerical value stored in the second storage unit, the control unit 5 sends the alarm sound generation unit 7 or
By operating, the user is made to sense a warning sound or vibration through the reception path.

Similarly, it is also possible to make the user sense a warning sound or vibration via the receiving path even when the first holding unit stored value <the second holding unit stored value.

FIG. 4 shows an example of the flow of the present invention. After or at the start of the audio signal input (so-called call), the user arbitrarily sets ON / OFF of the alarm sound setting. If the warning sound is OFF, the warning sound processing is terminated. When the alarm sound is ON, the count of the alarm sound detection timer is counted, and the audio signal is amplified by an amplifier which is a signal amplification unit of the audio processing unit at the count-up stage, and an A / D conversion unit which is an A / D conversion unit. To the container. Note that the count of the alarm sound detection timer is cleared, and the count is started again.

The audio signal converted into a digital signal in the above count-up stage is converted into a digital signal encoder (CODEC) as a digital signal encoder and a comparator 3
Send to. Further, the first holding unit 3 included in the comparison unit 3
1 is held as a measured value. Here, the initial specified value held in the second holding unit 32 is compared with the numerical value, and the comparison result is output to the control unit 5. For example, when the comparison result is that the first storage unit stored numerical value> the second storage unit stored numerical value, the control unit 5 operates the warning sound generation unit 7 or the body vibration unit 6 to use the control unit via the reception path. Make people sense warning sounds and vibrations.

As described above, in the portable telephone device, the comparison result of the comparison unit 3 is output to the alarm sound generation unit 7 or the control unit 5 which also controls the body vibration unit 6, and the alarm sound and the alarm sound are generated based on the data contents. By vibrating the body, the user can be urged to give a predetermined attention, and as a result, the manner of using the mobile phone device can be improved.

Instead of counting the count of the alarm sound detection timer, the alarm sound may be detected by using a count-up interrupt of the alarm sound detection timer as a trigger.
Furthermore, a comparison circuit (not shown) is built in the comparison unit 3 and the comparison result is a first storage unit stored value> second storage unit stored value or a first storage unit stored value <second storage unit stored value. In this case, the determination circuit may cause the control unit 5 to transmit an interrupt signal.
