The telephone device 1 is connected to a telephone line 31 by radio communication via an antenna 7 provided on the upper part of the main body 2.
[0014]
FIG. 2 is a block diagram showing an electrical configuration of the telephone device 1. The telephone device 1 includes a CPU 11, a ROM 12, a RAM 13, an audio LSI 17, a network control unit (NCU) 18, a tone detector 19, an amplifier 20, an LCD 5, an operation button 4, and a microphone 6. Are connected to each other.
[0015]
The NCU 18 is for line control, and is connected to the telephone line 31 by radio communication via the antenna 7. The NCU 18 receives a calling signal transmitted from the exchange 29, a telephone number (caller number) of the calling side device, and the like, and transmits a dial signal at the time of outgoing call according to the operation of the operation button 4 to the exchange 29. Furthermore, analog audio signals are transmitted and received during a call.
[0016]
The CPU 11 controls each unit connected by the bus line 30 according to various signals transmitted / received via the NCU 18 and executes a call process, a data communication process, and the like. The ROM 12 is a non-rewritable memory that stores various control programs executed by the telephone device 1 and fixed value data. The program shown in the flowchart of FIG. 3 is stored in the ROM 12. The RAM 13 is a memory for temporarily storing various data when each process of the telephone device 1 is executed.

[0017]
The audio LSI 17 converts an analog audio signal received by the NCU 18 into a digital audio signal, converts a digital audio signal generated inside the telephone device 1 into an analog audio signal, and outputs the analog audio signal to the NCU 18. is there. The tone detector 19 detects the telephone number of the calling side device transmitted from the exchange 29, and the amplifier 20 rings the speaker 3 connected to the amplifier 20 to generate a ringing tone and voice. It is for output.
[0018]
The telephone device 1 configured as described above is connected to the telephone line 31 by wireless communication via the NCU 18. The telephone line 31 is connected to the exchange 29, the exchange 29 is connected to another exchange via another telephone line 32, and the other exchange is further connected to the calling side device via the telephone line.
[0019]
Next, the call waiting process of the telephone device 1 configured as described above will be described based on the flowchart of FIG. This call waiting process is a process executed when a new call is received from another party during a call.
[0020]
When a new call is received during a call, a signal indicating the fact is transmitted from the exchange 29. When this signal is received, the telephone device 1 executes a call waiting process. In the call waiting process, first, an interrupt sound “Two ... Puppu, Puppu ...” is output from the speaker 3 (S1), and it is reported that a new call is made to the caller.
[0021]
When the callee's called device has subscribed to the “call waiting caller ID” service described in the prior art section and the calling device has not refused to notify the phone number The telephone number (caller number) of the calling side device is transmitted from the exchange 29. When the telephone device 1 receives this caller number (S2: Yes), the caller number is displayed on the LCD 5 in order to inform the caller of the new caller (S3). On the other hand, if the called party's called device has not subscribed to the “call waiting caller ID” service, or the calling device has refused to notify the telephone number, the exchange 29 Since the caller ID is not transmitted from (S2: No), in this case, the process of S3 is skipped and the process proceeds to S4.
[0022]
In general, when the caller recognizes that a new call has been received through the process of S1, the caller moves the telephone device 1 away from his / her face to see the caller number displayed on the LCD 5 in order to confirm the caller. When the telephone device 1 is separated from the face, the distance between the caller's mouth and the microphone 6 is increased, so that the voice sent to the other party is reduced and the telephone is farther away. Therefore, the input sensitivity of the microphone 6 is increased (S4) so that the telephone is not far away. Confirmation of the caller ID by the caller usually ends in 2 to 3 seconds. Therefore, in order to finish the state in which the input sensitivity of the microphone 6 is increased in, for example, about 3 seconds, a timer for measuring time for 3 seconds is started (S5).
[0023]
After the timer is started (S5) and before the time is up (S6: No), it is determined whether or not the input level to the microphone 6 has decreased (S7). If the input level to the microphone 6 is small (S7: small), the distance between the caller's mouth and the microphone 6 is large, that is, the telephone device 1 is separated from the caller's face. Therefore, in such a case, the volume of the speaker 3 is increased so that the caller can easily hear the voice of the other party (S8). On the other hand, if the input level to the microphone 6 remains normal (S7: normal), the telephone device 1 is not yet separated from the caller's face. In such a case, the volume of the speaker 3 is kept normal. (S9). That is, if the volume of the speaker 3 is increased in such a case, a loud sound is suddenly generated at the ear of the caller, which may surprise the caller or cause discomfort to the caller.
[0024]
As described above, when the telephone device 1 is separated from the caller's face and the distance between the caller's mouth and the microphone 6 increases, the input level to the microphone 6 decreases (S7: small), and the speaker 3 Is set to a large volume (S8). However, before the time is up (S6: No), when the telephone device 1 is returned to the caller's face, the input level of the caller's voice to the microphone 6 returns to normal (S7: Normally, the sound volume of the speaker 3 is returned to normal with the timing of the return (S9). As described above, even when the telephone device 1 is once separated from the caller's face and then returned to the original position, the caller does not feel uncomfortable due to excessive volume.
[0025]
After adjusting the volume of the speaker 3 (S7 to S9), it is checked whether the release key of the operation button 4 is pressed (S10). If the release key is not pressed (S10: No), the process proceeds to S6, and time up is determined (S6). As a result, the above-described processes of S6 to S10 are repeatedly executed until the time is up.
[0026]
On the other hand, when it is confirmed that the timer has expired in the process of S6 (S6: Yes), or when the release key of the operation button 4 is confirmed in the process of S10 (S10: Yes), The volume of the speaker 3 and the input sensitivity of the microphone 6 are returned to normal (S11, S12), the caller number displayed on the LCD 5 is deleted (S13), and the call waiting process is terminated.
[0027]
Note that the input sensitivity of the microphone 6 once increased by the process of S5 is maintained until the timer expires (S6). However, even before the timer expires, the input sensitivity of the microphone 6 can be restored by pressing the release key. Further, the caller ID display deletion process (S13) is not necessarily executed at the end of the call waiting process. For example, the process (S13) is executed at the end of a call or at the next new incoming call. You may make it do.
[0028]
As described above, according to the telephone device 1 of the present embodiment, when a new call is received during a call, the telephone number (caller number) of the newly called calling device is displayed on the LCD 5. In addition, the input sensitivity of the microphone 6 is increased. Therefore, even if the caller tries to look at the display on the LCD 5 in order to confirm the new caller, the telephone device 1 is moved away from the face and the caller's mouth and the microphone are separated from each other. It is possible to maintain a call without reducing the amount of voice that is played, that is, without leaving the phone far. The volume of the speaker 3 is increased according to the input level to the microphone 6. Therefore, the volume of the speaker 3 suitable for a call can be set, and it is possible to prevent the volume of the speaker 3 from suddenly increasing near the caller's ear.
[0029]
In the telephone apparatus according to claims 1 to 4, the processing of S3 is performed as the display means, the processing of S4 is performed as the microphone sensitivity increasing means, the processing of S12 is performed as the microphone sensitivity returning means, and the processing of S7 is performed as the detecting means. The processing corresponds to the processing of S8 as the speaker volume increasing means, and the processing of S9 and S11 as the speaker volume returning means. Further, the processing of S9 corresponds to the speaker volume restoration means in the telephone device according to claim 5.
[0030]
The present invention has been described above based on the embodiments. However, the present invention is not limited to the above embodiments, and various modifications can be easily made without departing from the spirit of the present invention. It can be guessed.
[0031]
For example, the present invention is not limited to a mobile phone or a cordless phone connected to a telephone line by radio.
