【0001】

[Industrial application field]

The present invention relates to a mobile communication device having a display unit capable of inputting information by key operation and displaying the information or the operation content thereof, and capable of transmitting / receiving and displaying information such as e-mail.

【0002】

[Conventional technology]

For example, there is a mobile phone as a mobile communication device capable of inputting information by key operation and displaying the information or the operation content thereof, and also capable of transmitting / receiving and displaying information such as e-mail. As shown in FIG. 1, a general mobile phone configuration is such that a mobile phone has a key-operated operation unit (1), a microphone for inputting a voice call (2), and a digital signal of the input voice signal. The voice input unit (3) that converts the input information into a predetermined signal form, the CPU (4) that converts the input information input from the operation keys or the microphone into a transmittable form, and the input or received character information. Alternatively, a display unit (5) that displays visible information such as image information, a transmission unit (6) that transmits information to be transmitted, an antenna (7) for transmitting and receiving information via a wireless line, and an antenna (7). A receiver (8) that converts the received information into a form that can be processed by the CPU (4), a duplexer (9) that switches the transmission and reception of information, and an audio output of the audio information received by the CPU (4). It is composed of a speaker (10) that performs the above.

【0003】

When composing and sending an e-mail on the mobile phone, character information is input using the operation unit (1) of the mobile phone. In this case, the output of the key monitor sound can be switched on and off according to the key operation. When the key monitor sound is set to on, the monitor sound is output each time one key is pressed. Also, if the key monitor sound is set to off, no key monitor sound is output even if a key operation is performed.

【0004】

[Problems to be Solved by the Invention]

As described above, in the prior art, when the key monitor sound is set to on, the key monitor sound is always emitted each time one operation key is pressed. In this case, since the key operations are frequent and the number of key inputs is large during the composing of the mail and the input of the mail document, the generation of the key monitor sound becomes very large. If the surrounding noise is loud, the key monitor sound is not a concern, but if the surroundings are quiet or you are on a train, the key monitor sound becomes noise for the people around you and causes discomfort. Become.

【0005】

On the other hand, when entering a telephone number for making a call, the user wants to make a key monitor sound for confirmation. However, if the key monitor sound is set to off, this request cannot be satisfied, and if the key monitor sound is set to on, the above-mentioned problems occur. Changing the key monitor sound setting each time a phone number is entered for making a call is a very troublesome operation.

【0006】

[Means for solving problems]

The present invention has been made in view of the above problems, has an operation unit used for inputting information for identifying a communication partner or character information, and emits a monitor sound each time the operation unit is operated. It also has a monitor sound control unit that sets whether or not to generate the monitor sound, and when character information is input, the monitor sound control unit automatically turns off the generation of the monitor sound. It is a portable communication device characterized in that the monitor sound is not emitted when character information is input by being switched.

【0007】

Further, it has a microphone and an operation unit used for inputting information for identifying a communication partner or character information, and it is possible to emit a monitor sound each time the operation unit is operated, and further, the monitor sound can be emitted. It has a monitor sound control unit that sets whether or not to generate noise, and an ambient noise determination unit that compares the ambient noise input from the microphone with a preset threshold value. The ambient noise determination unit has the ambient noise. When is smaller than the above threshold value, the monitor sound control unit automatically switches off the generation of the monitor sound, so that the monitor sound is not emitted in a quiet surrounding environment. But also.

【0008】

On the other hand, it has a microphone and an operation unit used for inputting information for identifying a communication partner or character information, and it is possible to emit a monitor sound each time the operation unit is operated, and further, the monitor sound can be emitted. It has a monitor sound control unit that sets whether or not to generate noise, and an ambient noise determination unit that compares the ambient noise input from the microphone with a preset threshold value. The ambient noise determination unit has the ambient noise. When is larger than the above threshold value, the monitor sound control unit automatically switches the generation of the monitor sound on.

【0009】

Further, the mobile communication device is also characterized in that it has a function of allowing the user to change the threshold value.

[Examples of the invention]

Hereinafter, examples of the present invention will be specifically described with reference to the drawings.

【0011】

The configuration of the mobile phone according to the present invention is as shown in FIG. 1, and is the same as the conventional one. Therefore, description thereof will be omitted here. Here, the input algorithm processed by the CPU (5), which is a feature of the present invention, will be described.

【0012】

A first embodiment of the present invention is shown in FIG. When the mobile phone is turned on (step 21), each port of the CPU is set by the initial process (step 22). After that, each function of the mobile phone is set to the factory default or the default set by the user (step 23). At this time, the key monitor sound is set in consideration of standby and incoming / outgoing calls. That is, for example, when the user wants to make a key monitor sound in response to a telephone number input when making a call, the key monitor sound is set to on, and when the user does not need to make a key monitor sound when making a call, the key monitor sound is not required to be generated. , Set the key monitor sound to off.

【0013】

Next, if you do not enter an email (step 25), perform normal operations such as standby or call (step 24), and if you enter an email (step 25), turn off the key monitor sound setting. Switch automatically (step 26). More specifically, for example, when the mail composition function is activated, the key monitor sound setting is automatically turned off.

【0014】

When you have finished entering the email (step 27), the key monitor sound settings are restored to their default settings (step 23).

【0015】

Next, a second embodiment of the present invention is shown in FIG. When the mobile phone is turned on (step 31), each port of the CPU is set by the initial process (step 32). After that, each function of the mobile phone is set to the factory default or the default set by the user (step 33). At this time, the key monitor sound is set in consideration of standby and incoming / outgoing calls. That is, for example, when the user wants to make a key monitor sound in response to a telephone number input when making a call, the key monitor sound is set to on, and when the user does not need to make a key monitor sound when making a call, the key monitor sound is not required to be generated. , Set the key monitor sound to off.

【0016】

Next, when the mail is not input (step 35), the normal operation such as the standby state or the call is performed (step 34). On the other hand, when inputting an email (step 35), for example, when the email composition function is activated, ambient noise is detected from the microphone (step 36), and the magnitude or sound pressure value of the ambient noise is a preset threshold value. In the above case (step 37), set the key monitor sound to on (step 38). If the magnitude or sound pressure value of the ambient noise is less than a preset threshold value (step 37), the key monitor sound is set to off (step 39).

【0017】

When you have finished entering the email (step 40), the key monitor sound settings are restored to their default settings (step 33).

【0018】

Next, a third embodiment of the present invention is shown in FIG. When the mobile phone is turned on (step 41), each port of the CPU is set by the initial process (step 42). After that, each function of the mobile phone is set to the factory default or the default set by the user (step 43).

【0019】

Next, the ambient noise is detected from the microphone (step 44), and if the magnitude or sound pressure value of the ambient noise is equal to or higher than the preset threshold value (step 45), the key monitor sound is set to on (step 46). ). If the magnitude or sound pressure value of the ambient noise is less than a preset threshold value (step 45), the key monitor sound is set to off (step 47).

【0020】

The operations of steps 44 to 47 are repeated continuously or intermittently regardless of whether it is a normal operation such as a standby state or an incoming / outgoing call operation, or a mail composing operation. Therefore, regardless of the type of operation of the mobile phone, the key monitor sound is automatically switched on and off according to the magnitude of ambient noise.

【0021】

Further, the threshold value described in the second and third embodiments of the present invention is set at the time of shipment from the factory, but the user may change the threshold value. The factory default threshold may be, for example, the loudness of the key monitor sound.

【0022】

Further, although step 38 in the second embodiment and step 46 in the third embodiment of the present invention have described an example in which the key monitor sound is turned on, the default setting may be maintained.

【0023】

Furthermore, the invention of the present application is not limited to the above-described embodiment, and there are various methods in which the technical idea of the present invention is used.

【0024】

[Effect of the invention]

According to the mobile communication device according to the present invention, the key monitor sound is automatically turned on and off according to the situation at that time without manually switching the key monitor sound on / off setting by dial input and mail input. Can be switched to. Therefore, the troublesomeness of the user manually resetting the key monitor sound depending on whether it is dial input, mail composition, or ambient noise is eliminated.

【0025】

In addition, the key monitor sound is automatically turned on and off according to the surrounding conditions, which helps prevent inconvenience to people around.
