Description

[0001]
[Industrial application fields]
The present invention relates to a radio selective call receiver, and more particularly to a radio selective call receiver capable of temporarily storing and reproducing not only a ringing tone but also received numbers and voice information.
[0002]
[Prior art]
As the use of radio selective call receivers becomes widespread, the service content is required to be highly functional and diversified. As an example of service contents currently being performed, there are calling, transmission of numbers, character information, and the like. Shorter voice information is also being transmitted. In Japanese Patent Laid-Open No. 3-60227, voice data input via a telephone network is A / D converted, the digital data is transmitted wirelessly, and wireless selection is performed. A technique is described in which digital data received by a call receiver is converted back to analog data by a D / A converter and output as sound from a speaker.
[0003]
[Problems to be solved by the invention]
In a radio selective call receiver capable of storing voice information in addition to numeric and character information, the radio selective call receiver usually reproduces numeric information and voice information and displays it on a display device by the operation of the carrier. Make an audio signal. In that case, when the mixed information of the numeric message and the voice message, or single information of either one is transmitted, the called party does not know the entire stored information, so the caller reads the numeric message and displays the voice information with a speaker or the like. You need to do all the listening operations. In addition, although the numeric message is obvious at a glance, since the existence of information is not known unless the voice message is reproduced, there is a troublesome thing that the called party always performs the reproduction operation. Further, since the end of the audio information is not known even during the audio reproduction, there is a problem that an irritating feeling that it will continue will occur. Furthermore, the radio selective call receiver is required to have low power consumption in order to reduce the frequency of battery replacement.
[0004]
An object of the present invention is to provide a radio selective call receiver that allows a called party to quickly grasp the type of stored information received. Another object of the present invention is to provide a radio selective call receiver that allows a called party to quickly grasp the amount of received voice information. Still another object of the present invention is to provide a radio selective call receiver that can prevent wasteful reproduction operation and consumes less power.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a radio selective call receiver having at least means for receiving and storing voice information, a means for checking the amount of voice information, and a display for displaying the amount of voice information. Means. The means for checking the information amount of the sound information includes the case of obtaining the information amount of the sound information stored in the storage means when there is only the presence or absence of sound. Although the said display means is not specifically limited, The presence or absence and amount of the information amount of audio | voice information are displayed with the display form which is easy to identify with a symbol, a color, and a graph.
[0006]
Further transmission information, in addition to voice information, text information, if the digits information, the other information such as the sign information is added, by adding a means for identifying the type of the received information on the display means, the display means Is configured to display the type of the received information. Although the display form is arbitrary, it is preferable to display the information of the type of received information with characters, colors or symbols so that it can be easily discriminated instantly.
[0007]
Furthermore, the reproducing unit of the receiving device is provided with driving means for the carrier to select and reproduce based on the information amount of the audio information and the display result of the type of the received information, that is, a selection switch and a reproduction switch. The means for checking the information amount of the audio information, the means for identifying the type of the received information, and the means for driving the display means may be provided with a dedicated device, but the microprocessor also serves as a demodulation operation of the receiver It is configured as a (microcomputer) function.
[0008]
[Action]
By displaying a character or symbol indicating that the voice information is stored in the storage means on the display, the called party who is the receiver's carrier can check whether the voice information included in the incoming message is present. Since it can be discriminated, it is possible to prevent useless reproduction operations for listening to audio information. In addition, since the called party can grasp the amount of stored voice information, the frustration of not knowing the end of the voice information can be eliminated, and the time to move to the next action can be predicted, thereby saving time. . In addition, the playback circuit does not operate even if there is no audio information, and the playback circuit does not operate. Therefore, wasteful current consumption of the circuit can be suppressed, the internal battery can be saved, and the substantial battery life can be extended. it can.
