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 A conventional portable telephone device has 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 single digit numbers of "0" to "9", an "outgoing" button for starting a call, and an "end" button for ending a call. At a minimum, they are present in mobile telephone devices. Some mobile phone devices have a function button for expanding other functions.

[0003] In such a portable telephone device, a beep sound is emitted from a built-in speaker as a push button switch press confirming sound at the time of press so that the operator can confirm that the push button switch has been pressed. The content defined for the pressed push button switch is displayed on the display.

[0004] On the other hand, such a portable telephone device has a function of restricting the generation of a push button switch pressing confirmation sound, assuming a use scene in a place where a confirmation sound when the push button switch is pressed cannot be output. . This state in which the confirmation sound is restricted is called a silent mode. Conversely, the state in which the above-mentioned confirmation sound can be output is referred to as a pressing confirmation sound output mode.

Further, the conventional portable telephone device has a function of, when there is a call from a call partner, that is, an incoming call, indicating the incoming call by blinking a lamp together with the incoming call sound caused by intermittent beep sounds. 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, a signal from a partner terminal is received by an antenna 1, received and demodulated by a receiver 3 via a duplexer 2, and then supplied to a handset 16 via a telephone control unit 21. The audio signal from the handset 16 is supplied to the transmitter 4 via the telephone control unit 21, where it is modulated and then transmitted wirelessly via the duplexer 2 and the antenna 1.

[0007] The conventional portable telephone device for performing such a call operation has a push button switch 9 which is an aggregate of a plurality of push button switches, and each of the plurality of push button switches 9 has a unique one. Outgoing code is defined.

Therefore, when the push-button switch 9 is pressed, a transmission code unique to the pressed push-button switch is detected by the push-button press detection circuit 10, and a detection signal output from the push-button press detection circuit 10 only at the time of the detection. Is supplied to the beep sound transmitter 13 via the OR circuit 11 and the switch circuit 22 in series to drive the beep sound transmitter 13. As a result, a beep sound signal is output from the beep sound transmitter 13, is amplified by the amplifier 14, is supplied to the speaker 15, is subjected to electro-acoustic conversion, and emits a beep sound as a push button switch pressing confirmation sound.

The telephone control unit 21 outputs an alarm sound to alert the operator when the operator makes an operation error or when the voltage of a battery (not shown) falls 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 to drive it. Thus, a beep sound is emitted from the speaker 15 as an alarm sound in the same manner as when the push button switch 9 is pressed.

The telephone control unit 21 is provided with a switch circuit 2
2 outputs a switching signal to the switching circuit 2 normally.
2 is turned on as shown in the figure. 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 generates a beep sound of the drive signal extracted from the OR circuit 11. The supply to the transmitter 13 is cut off, and the
Suppressing of a beep sound such as a push button switch pressing confirmation sound caused by 5 is suppressed.

Further, based on the demodulated signal from the receiver 3, the telephone control section 21 blinks the incoming call indicator lamp 7 at the time of an incoming call, generates a drive signal of a pulse train, and connects the OR circuit 11 and the switch circuit 22 in series. The signal is supplied to the beep sound transmitter 13 via the speaker 15 so that the speaker 15 emits an intermittent beep sound indicating an incoming call.

The telephone control section 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 employed as means for confirming the depression of the push button switch 9. The first method is a method in which a beep sound for confirming the push button is emitted from the speaker 15 in conjunction with the depression of the push button switch 9, and the depression of the push button switch 9 is confirmed by sound.

A second method is to display the definition of the pressed push-button switch 9 on the display 8 so that the operator can visually confirm that the push-button switch 9 has been pressed.

[0015]

However, in the above-described conventional portable telephone device, when the pressing of the push button switch 9 is confirmed by the first method in the silent mode, the sound of the push button switch pressing confirmation sound is generated. Since the output is suppressed, the confirmation with the push button switch confirmation sound becomes impossible.

Therefore, in the silent mode, the depression of the push button switch 9 is confirmed by the above-mentioned second method. However, when an operation error occurs due to the calling of an undefined function, the display 8 is turned off. Since the display contents do not change, the operator can determine whether the push button switch 9 is malfunctioning, whether the push button switch 9 is not pressed correctly, or whether an operation error has occurred and the display does not change. There is a problem that cannot be clarified.

The present invention has been made in view of the above points,
It is an object of the present invention to provide a portable telephone device capable of visually and clearly discriminating confirmation of pressing of a push button switch in a silent mode.

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

[0019]

[0020]

[0021]

According to the present invention, the output detection signal of the push button press detection circuit is output to the transmitter as a drive signal in the press confirmation sound output mode, so that the output voice signal of the transmitter is transmitted from the speaker to the push button switch. It is pronounced each time it is pressed. In the silent mode, the output detection signal of the push button press detection circuit is switched by the switch and the second switch .
Since the driving signal is switched and input to the incoming call indicating lamp through the logic circuit, the incoming call indicating lamp is turned on when the push button switch is pressed.

Further, according to the present invention, an intermittent signal is sent from the control unit when an alarm is issued to the device or when the operation of the push button switch is erroneously performed.
Since the signal is input to the changeover switch via the first logic circuit, in the pressing confirmation sound output mode, the transmitter is driven by the intermittent signal extracted from the changeover switch and the sound signal is output intermittently. An intermittent tone is emitted as an alarm sound. On the other hand, in the silent mode , the intermittent signal extracted from the control unit via the changeover switch is transmitted to the first logic circuit, the changeover switch.
And a drive signal to the incoming call indicator lamp through the second logic circuit
Is input , the incoming call indicator lamp flashes.

[0023]

Next, an embodiment of the present invention will be described. FIG. 1 shows a configuration diagram of an embodiment of the mobile phone device according to the present invention. 2, the same components as those in FIG. 2 are denoted by the same reference numerals. As shown in FIG. 1, this embodiment includes an antenna 1, a duplexer 2, a receiver 3, and a transmitter 4 that constitute communication means for performing wireless communication with a nearest communication base station (not shown);
A telephone control unit 5 for controlling each unit of the apparatus; a two-input OR circuit 6; an incoming call indicator lamp 7 for notifying an incoming call;
, A plurality of push button switches 9 each defining a unique transmission code, and an arbitrary push button switch 9
, A push-button press detection circuit 10 for detecting press-down, a two-input OR circuit 11, a changeover switch 12, a beep sound transmitter 13 for transmitting a beep sound signal as 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, the changeover switch 12 is provided between the output terminal of the OR circuit 11 and the input terminal of the beep sound transmitter 13 and the OR circuit 6 is provided The difference is that an OR circuit 6 for taking 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 that of the conventional telephone control unit 21.

The antenna 1 is used for both transmission and reception of radio waves, and transmits and receives radio waves to and from a 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 a received signal from the communication base station input through the duplexer 2, reproduces a control signal from the communication base station, and inputs the control signal to the telephone controller 5, The audio signal transmitted from the communication base station is reproduced, supplied to the handset 16 through the telephone control unit 5, and output as audio.

The transmitter 4 receives control information transmitted from the telephone control unit 5 to the communication base station, further amplifies a modulated wave signal obtained by performing modulation by a predetermined modulation method, and passes through the duplexer 2 Radio transmission from the antenna 1 or reception of a voice signal from the handset 16 through the telephone control unit 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 section 5 controls the entire portable telephone device. The telephone control unit 5 has a power control function of the mobile phone device, a processing function of receiving an operation from the operator input from the push button switch 9, a function of processing and displaying the content 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 and receiving a transmission / reception voice signal, and a flashing of a reception indicator lamp 7 when a call is made from a communication partner. Has a function.

The display 8 receives control from the telephone control unit 5 and displays an operation guide message, a telephone number pressed by the push button switch 9, and the like. The push button switch 9 receives a telephone number input, a mode instruction input such as a pressing confirmation sound output mode and a silent mode, and an operation input for selecting various functions. The amplifier 14 amplifies the beep signal (voice signal) output from the beep transmitter 13 and inputs the amplified signal to the speaker 15. As is well known, the speaker 15 performs an electro-acoustic conversion of the input audio signal and outputs a sound wave.

The push button press detection circuit 10 generates a detection signal when detecting that the push button switch 9 is pressed, and supplies the detection signal to the OR circuit 11. The telephone controller 5 generates an intermittent signal (pulse train) for the purpose of alerting the operator when the operation of the push button switch 9 is erroneously operated or the voltage of the battery 17 drops below a predetermined value, and supplies this to the OR circuit 11. I do.

Accordingly, the OR circuit 11 performs a logical OR operation of the detection signal from the push button press detection circuit 10 and the intermittent signal from the telephone control unit 5, and obtains a signal (this signal is hereinafter referred to as an 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, the terminal is switched to the terminal 12b and selectively output to the OR circuit 6.

Next, the operation of the above-described embodiment of the present embodiment in the pressing confirmation sound output mode and the silent mode will be described. First, in the pressing confirmation sound output mode, the telephone control unit 5 controls connection of the changeover switch 12 to the terminal 12a. Thereby, 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 sound signal corresponding to the input drive signal,
The signal is supplied to the speaker 15 via the amplifier 14 and is emitted. Therefore, in the press confirmation sound output mode, a beep sound is emitted from the speaker 15 in response to the press of the push button switch 9 as in the related art, and the operator can confirm the press of the push button switch 9.

When the operator makes an operation error (operation error), or when the output voltage of the battery 17 drops below a predetermined value, the ATTN signal is output from the OR circuit 11. 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 is also an intermittent signal, whereby the beep sound transmitter 13 is also intermittently driven. Therefore, in this case, assuming that the above-mentioned intermittent signal is a pulse train composed of three pulses having a short pulse width, the sound signal is output from the beep sound transmitter 13 three times each for a short period. With this burst-like audio signal, a continuous short beep is generated
Rings twice. Accordingly, 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 section 5 switches the changeover switch 12 to the terminal 12b side and connects it. Therefore,
The output ATTN signal of the OR circuit 11 is set to the changeover switch 1
The OR signal is supplied to the OR circuit 6 through the terminal 2 and is ORed with a lamp drive signal output from the telephone control unit 5 at the time of an incoming call.

Therefore, when the push button switch 9 is pressed in the silent mode, the push button press detection signal is supplied to the incoming call indicator lamp 7, so that the incoming call indicator lamp 7 is turned on every time the push button switch 9 is pressed. I do.
This allows the operator to confirm that the push-button switch 9 has been reliably pressed because the incoming-call display lamp 7 is turned on in accordance with the operation of pressing the push-button switch 9.

The ATTN signal is also output from the OR circuit 11 when the operator makes an operation error (operation error) or when the output voltage of the battery 17 drops below a predetermined value. 7 lights up. However, as described above, since the ATTN signal in this case is a pulse train composed of three pulses having a short pulse width output from the telephone control unit 5, the incoming call indicator lamp 7 blinks three times. Accordingly, 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, the display unit 8 operates as in the case where an operation error occurs due to a call of an undefined function or the like.
Even when the display content of does not change, the incoming call indicator 7
Because of the blinking twice, the occurrence of an operational error can be identified.

When the incoming call indicating lamp 7 is turned on or off in accordance with the operation of pressing the push button switch 9, it can be recognized that the operator has not pressed the push button switch 9 correctly. Further, when the push button switch 9 is out of order, the incoming call indicator lamp 7 remains off even if the operator presses a 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-described embodiment. For example, it is not possible to distinguish between a warning and an alarm. However, a means for transmitting the vibration of the diaphragm to the operator is used instead of the incoming call display lamp 7. This allows the operator to identify at least the pressing of the push button switch. In addition, the number of beep sounds generated at the time of alarm and the incoming call indicator lamp 7
Is not limited to three times.

[0040]

As described above, according to the present invention,
In the silent mode, the incoming call indicator light is turned on in response to the press of the push button switch, so that the operator can recognize that the push button switch is being pressed reliably, and if the push button switch fails, And whether the push button switch is not pressed down accurately can be distinguished, and the operability of the push button switch can be improved.

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