Further, on the back surface of the upper case 12, a loudspeaker 16 as shown in FIG.
[0008]
FIG. 2 shows a circuit block diagram of the mobile telephone according to the embodiment of the present invention as described above. This block diagram shows an RF circuit 42 connected to an antenna 41 for performing transmission / reception operations, a digital signal processor (DSP) 43 for digitally processing transmission / reception signals, and a received signal output from the DSP 43 as a D / A. The D / A converter 44 for conversion, the reception speaker 15 shown in FIG. 1 connected to the output of the D / A converter 44 and reproducing the D / A converted reception signal, and similarly the D / A converter 44, connected to the output 44, and used for switching to the reception speaker 15 when responding to a hands-free call, the transmission microphone 13 shown in FIG. 1 for inputting the voice of the speaker, and the transmission An A / D converter 45 that A / D converts the transmission signal input from the microphone 13 and outputs the converted signal to the DSP 43, a CPU unit 46 that controls the whole, and the CPU 46, a memory 47 and a ROM 48 for storing programs and various data, and similarly connected to the CPU unit 46 for inputting various types of information, as shown in FIG. The display unit 14 is also connected to the display unit driver 49 and displays various kinds of information.
[0009]
In the mobile telephone as described above, a hands-free call response (hereinafter referred to as a hands-free voice response) can be selected and set from a plurality of response methods. In that case, first, as shown in step S1 of FIG. 3, the response selection menu is selected from the basic menu by key operation. Then, the screen of the display unit 14 becomes a response method selection screen as shown in step S2 of FIG. 3, and the screen displays “bell stop (stop ringtone and vibration)” “hands-free voice response” “response (normal response)” “Voice mail center transfer”, “Simple answering response (simple answering record)”, “Response hold (reproduction of hold message)” and “OFF (response operation by best voice key 31 prohibited)” are displayed. Here, “hands-free voice response” is selected from the choices by key operation. Then, the screen of the display unit 14 becomes a hands-free voice response setting completion screen as shown on the left side of step S3 in FIG. 3, a setting completion sound is sounded, and the hands-free voice response setting operation is completed. If “OFF” is selected in step S2, an OFF setting completion screen shown on the right side of step S3 is displayed, and a setting completion sound is emitted at the same time, and a response operation by the best voice key 31 described later is prohibited. After completing these settings, it is possible to return to step S1 by a key operation or timeout.
[0010]
When the hands-free voice response is set as described above, when the incoming call is received, the best voice key 31 shown in FIG. Free voice response is possible. Therefore, it is possible to talk with the other party without holding the mobile telephone by hand. Here, the best voice key 31 is provided on the side surface of the lower case 11 so that the lower case 11 and the upper case 12 can be operated in either a folded state or an opened state. Therefore, according to the mobile phone, regardless of whether the case is folded or opened, the best voice key 31 can be pressed to make a hands-free voice response.
[0011]
As shown in FIG. 1, the microphone 13 is provided at the lower end of the front surface of the lower case 11, and even when the case is folded, when the hands-free voice is answered, the upper case 12 and the lower case 11 The speaker's voice can be picked up with high sensitivity from the gap. Further, the loudspeaker speaker 16 reproduces the received sound from the back surface of the upper case 12 during a hands-free voice response.
[0012]
Further, when the case is folded during the hands-free voice response in this way, if the case is opened and then the first soft key 28 in the operation key 20 is pressed, as shown in FIG. It is possible to switch from voice response (step S11) to normal response (a method of holding a mobile telephone in hand and placing the receiving speaker 15 on the ear to make a call; step S12). Furthermore, if the first soft key 28 is pressed in the normal response state, it is possible to return to the hands-free voice response. That is, each time the first soft key 28 is pressed, the hands-free voice response and the normal response can be switched alternately.
[0013]
As described above, according to the above mobile phone, a hands-free voice response can be made by simply pressing the best voice key 31 once. Therefore, even while working with both hands, it is possible to respond to an incoming call without interfering with the current work, improving usability. In addition, the best voice key 31 is provided on the side surface of the lower case 11 and can be operated in either the folded state or the opened state, so that the folded case is not opened. In addition, regardless of the folded state and the opened state, an incoming call can be immediately answered, and the usability is further improved.
[0014]
Furthermore, the foldable mobile phone 61 is set in the charger 62 as shown in FIG. 5 in a folded state, but the hands are free by operating the best voice key 31 on the side surface of the lower case 11 while being folded. According to the mobile telephone 61 that allows voice response, the best voice key 31 can be operated while the mobile telephone 61 is set in the charger 62 to enable a hands-free voice response, which further improves usability. . At this time, the back surface of the upper case 12 is an upper surface (an open surface that is not obstructed by the lower charger 62), and the loudspeaker 16 is disposed here. At this time, it may be set to the hands-free response by detecting that the battery charger 62 is set.
[0015]
When the case is folded, the call can be disconnected by pressing the best voice key 31 at the end of the call. Alternatively, the call may be disconnected when a certain time has elapsed after the call ends.
[0016]
In the mobile telephone according to the present embodiment, the case where the lower end of the upper case 12 is connected to the upper end of the lower case 11 so as to be foldable is described. However, the case where the upper case slides and covers the lower case is described. Even so, it is the same.
[0017]
