Abstract

PURPOSE: To provide a portable telephone set in which the confirmation of the depression of a push-button switch in a silent mode can be visually and clearly discriminated and the alarm on an operation mistake, etc., can be visually and clearly discriminated. CONSTITUTION: At the time of a silent mode, a telephone set control part 5 switches a changeover switch 12 to the side of a terminal 12b and connects the switch 12 with the side. When a push-button switch 9 is depressed, a push- button depression detection circuit 10 supplies a detection signal as a driving signal to an incoming display lamp 7 through an OR circuit 11, a changeover switch 12 and an OR circuit 6 and turns on the incoming display lamp 7 every time the push-button switch 9 is depressed. When an operation mistake is generated by an operator, the incoming display lamp 7 flickers three times because the telephone set control part 5 generates three pulses and supplies the pulses as the driving signals to the incoming display lamp 7 through the OR circuit 11, the changeover switch 12 and the OR circuit 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone device, and more particularly to a portable telephone device having a function of confirming depression of a plurality of push button switches as constituent elements.

[0002]

2. Description of the Related Art Conventionally known general mobile phone devices have a plurality of push button switches as constituent elements. As this push button switch, for example,
There are a total of nine dial buttons for entering each one-digit number from "0" to "9", a "call" button for starting a call, an "end call" button for ending a call, etc. At a minimum, it is present in mobile phone devices. In addition, some mobile phone devices have function buttons for expanding other functions.

In such a portable telephone device, in order to make the operator confirm that the push button switch has been pressed, a beep sound is emitted from the built-in speaker as a push button switch pressing confirmation sound at the time of pressing, and The contents defined in the pressed push button switch are displayed on the display.

On the other hand, such a portable telephone device has a function of restricting the generation of the push button switch depression confirmation sound, assuming a use scene in a place where the confirmation sound when the push button switch is depressed cannot be produced. . The state in which the generation of this confirmation sound is restricted is called a silent mode. On the contrary, the state in which the above confirmation sound can be produced is called a press confirmation sound output mode.

Further, the conventional portable telephone device has a function of indicating an incoming call by blinking a lamp together with a ringing tone due to intermittent beeping sound when there is a call, that is, an incoming call from the other party. This lamp is generally called an incoming call indicator lamp.

FIG. 2 is a block diagram showing an example of a conventional portable telephone device. In the figure, the signal from the partner terminal is received by the antenna 1, received and demodulated by the receiver 3 via the duplexer 2, and then supplied to the handset 16 via the telephone control unit 21. Also, the voice signal from the handset 16 is supplied to the transmitter 4 via the telephone control unit 21, modulated here, and then wirelessly transmitted via the duplexer 2 and the antenna 1.

A conventional portable telephone device for performing such a call operation has a push button switch 9 which is an assembly of a plurality of push button switches, and each of the plurality of push button switches 9 is unique. The sending code is defined.

Therefore, when the push button switch 9 is pushed, the sending code peculiar to the pushed push button switch is detected by the push button depression detecting circuit 10, and the detection signal output from the push button depression detecting circuit 10 only at the time of detection. Is supplied to the beep sound transmitter 13 via the OR circuit 11 and the switch circuit 22 in series to drive it. As a result, a beep sound signal is output from the beep sound transmitter 13, amplified by the amplifier 14, and then supplied to the speaker 15 for electro-acoustic conversion, and a beep sound is emitted as a push button switch pressing confirmation sound.

The telephone control unit 21 also outputs a warning sound for the purpose of alerting the operator when the operator makes an operation error or when the voltage of a battery (not shown) drops below a predetermined value. For this purpose, a drive signal is generated and supplied to the beep sound transmitter 13 via the OR circuit 11 and the switch circuit 22 in series and driven. As a result, similarly to when the push button switch 9 is pressed, a beep sound is emitted from the speaker 15 as an alarm sound.

Further, the telephone control unit 21 has a switch circuit 2
2 outputs a switching signal to the switch circuit 2
2 is in the on state as shown. However, when a silent mode instruction is input by operating the push button switch 9, the telephone control unit 21 generates a switching signal for turning off the switch circuit 22, and the beep sound of the drive signal extracted from the OR circuit 11 is generated. The power supply to the transmitter 13 is cut off, so that the speaker 1
The generation of a beep sound such as a push button switch pressing confirmation sound by 5 is suppressed.

Further, the telephone control unit 21 blinks the incoming call indicator lamp 7 at the time of incoming call based on the demodulated signal from the receiver 3 and generates a pulse train drive signal to serially connect the OR circuit 11 and the switch circuit 22. It is supplied to the beep sound transmitter 13 via the speaker 15 to cause the speaker 15 to emit an intermittent beep sound indicating an incoming call.

Further, the telephone control unit 21 displays the contents on the display 8 when the push button switch 9 is operated, when an alarm is issued, and when an incoming call is received.

Therefore, in the conventional portable telephone device which operates as described above, two methods are adopted as means for confirming the depression of the push button switch 9. The first method is a method of interlocking with the depression of the push button switch 9 to generate a beep sound for push button confirmation from the speaker 15 to confirm the depression of the push button switch 9 by sound.

The second method is to display the definition contents of the pushed push button switch 9 on the display 8 so that the operator can visually confirm the depression of the push button switch 9.

[0015]

However, in the above-mentioned conventional portable telephone device, when the depression of the push button switch 9 is confirmed by the first method in the silent mode, a confirmation sound of the push button switch depression is given. Since the output is suppressed, it becomes impossible to confirm with the push button switch confirmation sound.

Therefore, in the silent mode, the pressing of the push button switch 9 is confirmed by the second method described above. However, in the case of an operational error due to calling of an undefined function, the display 8 is displayed. Since the display contents do not change, the operator can distinguish whether the push button switch 9 is out of order, the push button switch 9 is not pressed correctly, or the display does not change due to an operation error. However, there is a problem that it cannot be clarified.

The present invention has been made in view of the above points,
An object of the present invention is to provide a mobile phone device capable of visually and clearly identifying confirmation of pressing of a push button switch in silent mode.

Another object of the present invention is to provide a portable telephone device that can visually and clearly identify an alarm such as an operation error.

[0019]

In order to achieve the above object, the present invention achieves the above object by using a communication means for performing wireless communication with the nearest communication base station and a voice signal received via the communication means. A handset that converts and converts the input voice into a voice signal and sends it by communication means, a plurality of push button switches each having a unique transmission code defined, and any push button switch among the plurality of push button switches. A push-button depression detection circuit for detecting depression of the button, an oscillator driven by an input drive signal to transmit an audio signal, and a speaker for producing an audio signal emitted by the oscillator,
An incoming call display lamp that displays an incoming call when there is a call from the other party, and an output detection signal of the push button press detection circuit in the push confirmation sound output mode is output to the transmitter as a drive signal, and a push button press is detected in the silent mode. A changeover switch that outputs the output detection signal of the circuit to the incoming call indicator lamp as a drive signal, and at the same time when the incoming call is detected based on the received signal input via the communication means, the incoming call indicator lamp is turned on and a mode instruction by a push button switch And a control unit for controlling the switching of the changeover switch based on the above.

Further, according to the present invention, the control unit has a function of generating an intermittent signal when an alarm of the device is generated or an operation error of the push button switch is made, and the intermittent signal and the detection signal from the push button press detecting circuit are combined. The configuration is such that a logic circuit for inputting a signal obtained by taking the logical sum to the changeover switch is provided.

[0021]

In the present invention, since the output detection signal of the push button press detection circuit is output to the oscillator as the drive signal in the press confirmation sound output mode, the output audio signal of the oscillator is output from the speaker through the push button switch. Sounds every time the button is pressed. Also, in the silent mode, the output detection signal of the push button press detection circuit is switched to the incoming display lamp as a drive signal by the changeover switch,
The incoming call indicator lamp lights up when the push button switch is pressed.

Further, in the present invention, since the intermittent signal is inputted from the control section to the changeover switch through the logic circuit when the alarm of the apparatus or the operation of the push button switch is mistaken, it is taken out from the changeover switch in the pressing confirmation sound output mode. The generated intermittent signal drives the oscillator to intermittently output the audio signal, and as a result, the intermittent sound is emitted from the speaker as an alarm sound. On the other hand, in the silent mode, since the incoming call indicator lamp is driven by the intermittent signal taken out from the control unit through the changeover switch, the incoming call indicator lamp blinks.

[0023]

Next, an embodiment of the present invention will be described. FIG. 1 is a block diagram of an embodiment of a mobile phone device according to the present invention. In the figure, the same components as those in FIG. 2 are designated by the same reference numerals. As shown in FIG. 1, in this embodiment, an antenna 1, a duplexer 2, a receiver 3 and a transmitter 4 which constitute a communication means for performing wireless communication with a nearest communication base station (not shown),
Telephone control section 5 for controlling each section of the apparatus, two-input OR circuit 6, incoming call indicator lamp 7 for notifying an incoming call, and indicator 8
, A plurality of push button switches 9 each having a unique transmission code defined, and arbitrary push button switches 9
A push button depression detection circuit 10 for detecting depression of the button, a 2-input OR circuit 11, a changeover switch 12, and a beep sound transmitter 13 for emitting a beep sound signal which is an audio signal,
It comprises an amplifier 14 for amplifying a beep sound signal, a speaker 15 for producing a beep sound, a handset 16 and a battery 17 for supplying a DC power supply voltage to each part of the apparatus.

That is, in this embodiment, as compared with the conventional device, the changeover switch 12 is provided between the output end of the OR circuit 11 and the input terminal of the beep sound transmitter 13 and the OR circuit 6 of the telephone controller 5. The difference is that an OR circuit 6 that takes the logical sum of the output signal and the output signal of the changeover switch 12 is provided, and the control operation of the telephone control unit 5 is different from the conventional telephone control unit 21.

The antenna 1 is commonly used for transmitting and receiving radio waves, and transmits and receives radio waves to and from the nearest communication base station (not shown). The duplexer 2 transmits the transmission signal from the transmitter 4 to the antenna 1 and does not transmit it to the receiver 3, and transmits the reception signal from the antenna 1 only to the receiver 3.

The receiver 3 detects and demodulates the received signal from the communication base station input via the duplexer 2, reproduces the control signal from the communication base station, and inputs it to the telephone controller 5. The voice signal sent from the communication base station is reproduced and supplied to the handset 16 through the telephone controller 5 to be output as voice.

The transmitter 4 receives the control information transmitted from the telephone controller 5 to the communication base station, further modulates the modulated wave signal obtained by performing the modulation in the predetermined modulation method, and passes the signal through the duplexer 2. Wirelessly transmit from the antenna 1 or receive a voice signal from the handset 16 through the telephone controller 5,
A modulated wave signal obtained by performing modulation by a predetermined modulation method is further amplified and wirelessly transmitted from the antenna 1 through the duplexer 2.

The telephone control unit 5 controls the entire mobile telephone device. The telephone control unit 5 has a power control function of the mobile telephone device, a processing function of accepting an operation from the operator input from the push button switch 9, and a function of processing and displaying contents displayed on the display unit 8. An air interface function for exchanging control information with a communication base station, a path control function for transmitting / receiving a voice signal for transmission / reception, and a blinking control of an incoming call indicator lamp 7 when a call partner calls It has a function.

The display unit 8 is controlled by the telephone control unit 5 and displays an operation guide message, a telephone number depressed by the push button switch 9 and the like. The push button switch 9 accepts a telephone number input, a mode confirmation input such as a press confirmation sound output mode and a silent mode, and an operation input for selecting various functions. The amplifier 14 amplifies the beep sound signal (audio signal) output from the beep sound transmitter 13 and inputs it to the speaker 15. As is well known, the speaker 15 electro-acoustically converts an input audio signal and outputs a sound wave.

The push button depression detection circuit 10 generates a detection signal when detecting that the push button switch 9 is depressed, and supplies the detection signal to the OR circuit 11. The telephone control unit 5 generates an intermittent signal (pulse train) for the purpose of calling the operator's attention when the push button switch 9 is operated incorrectly or the voltage of the battery 17 drops below a predetermined value, and supplies this to the OR circuit 11. To do.

Therefore, the OR circuit 11 takes the logical sum of the detection signal from the push button depression detection circuit 10 and the intermittent signal from the telephone control section 5, and obtains the signal (this signal is hereinafter referred to as ATTN signal). Is supplied to the changeover switch 12. Changeover switch 1
2 is connected to the terminal 12a and selectively outputs the input ATTN signal to the beep sound transmitter 13 in the press confirmation sound output mode based on the switching signal from the telephone control unit 5;
In the silent mode, it is switched and connected to the terminal 12b and selectively output to the OR circuit 6.

Next, the operation in the press confirmation sound output mode and the silent mode of the present embodiment having the above-mentioned configuration will be described. First, in the pressing confirmation sound output mode, the telephone control unit 5 controls the connection of the changeover switch 12 to the terminal 12a side. As a result, the output ATTN signal of the OR circuit 11 is supplied as a drive signal to the beep sound transmitter 13 through the changeover switch 12, so that the beep sound transmitter 13 outputs a section audio signal corresponding to this input drive signal.
It is supplied to the speaker 15 via the amplifier 14 and sounded. Therefore, in the pressing confirmation sound output mode, a beep sound is emitted from the speaker 15 in response to the pressing of the push button switch 9, and the operator can confirm the pressing of the push button switch 9 as in the conventional case.

Also, when the operator makes an operation error (operation error) or when the output voltage of the battery 17 drops below a predetermined value, the ORTN 11 outputs the ATTN signal. A beep sounds. However, in this case, since the intermittent signal is output from the telephone control unit 5 to the OR circuit 11 as described above, A
The TTN signal also becomes an intermittent signal, whereby the beep sound transmitter 13 is also driven intermittently. Therefore, in this case, assuming that the intermittent signal is a pulse train consisting of three pulses having a short pulse width, the beep sound transmitter 13 outputs an audio signal three times in a short period, so that the speaker 15 is A continuous short beep is generated by this burst-type audio signal.
Sounds once. Thus, the operator can recognize the beep sound at this time as an alarm sound that is clearly different from the beep sound when the push button switch 19 is pressed.

Next, the operation in the silent mode will be described. In this case, the telephone control unit 5 switches and connects the changeover switch 12 to the terminal 12b side. Therefore,
The output ATTN signal of the OR circuit 11 is the changeover switch 1
It is supplied to the OR circuit 6 through 2 and is ORed with the lamp drive signal output from the telephone control section 5 at the time of an incoming call, and then is supplied to the incoming call display lamp 7 as a drive signal.

Therefore, in the silent mode, when the push button switch 9 is pressed, the push button pressing detection signal is supplied to the incoming call indicator lamp 7, so that the incoming call indicator lamp 7 lights up every time the push button switch 9 is depressed. To do.
As a result, the operator can confirm that the push button switch 9 has been pressed reliably because the incoming call indicator lamp 7 lights up in accordance with the operation of pressing the push button switch 9 by himself / herself.

When the operator makes an operation error (operation error) or when the output voltage of the battery 17 drops below a predetermined value, the OR circuit 11 outputs the ATTN signal, so that the incoming call indicator lamp 7 lights up. However, as described above, since the ATTN signal in this case is a pulse train consisting of three pulses with a short pulse width output from the telephone control unit 5, the incoming call indication lamp 7 blinks three times. Thereby, the operator can confirm that the alarm is an operation error or a voltage drop of the battery 17.

As described above, according to the present embodiment, in the silent mode, as in the case where an operational error occurs due to calling of an undefined function, the display 8
Even if the display content of does not change, the incoming display lamp 7
Blinks twice to identify operational errors.

When the incoming call indicator lamp 7 lights up or does not light up in accordance with the operation of pressing the push button switch 9, it can be identified that the operator is not pressing the push button switch 9 accurately. Further, when the push button switch 9 is out of order, the incoming call indicator lamp 7 remains off even if the operator presses the plurality of push button switches 9, so that the push button switch 9 is out of order. I understand.

The present invention is not limited to the above-mentioned embodiment. For example, although it is indistinguishable from an alarm, a means for transmitting the vibration of the diaphragm to the operator is used instead of the incoming call indicator lamp 7. This allows the operator to identify at least the pressing of the push button switch. Also, the number of times the beeper sounds at the time of alarm and the incoming call indicator lamp 7
Needless to say, the number of blinking of is not limited to three.

[0040]

As described above, according to the present invention,
In the silent mode, the incoming call indicator lamp lights up in response to the push button switch being pressed, so the operator can recognize that he / she is surely pressing the push button switch, and if the push button switch fails. It is possible to distinguish whether the push button switch is pressed correctly or not, and it is possible to improve the operability of the push button switch.

Further, according to the present invention, in the silent mode, when an operation error or an operation error occurs, or when the battery voltage drops below a predetermined value, the intermittent operation is taken out from the control unit via the changeover switch. Since the incoming call indicator lamp is made to blink by the signal, the operator can clearly identify the occurrence of an alarm such as an operation error.
