DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device having a speaker for transmitting a transmission sound to the surroundings.

[0002]

2. Description of the Related Art A telephone device having a speaker for transmitting a transmission sound to the surroundings (see Japanese Patent Publication No. 3-145246) is conceivable, and a time signal, a weather forecast, music and the like can be heard by surrounding people. Now you can.

[0003]

However, in the past, a conventional speaker for a telephone call and a speaker for a monitor were switched. For this reason, when monitoring, the transmission sound is not transmitted from the normal speaker, and the user must listen to the reception sound from the monitor speaker instead of the normal communication speaker.

Or a conversion between analog and digital, and changes the reception volume and microphone sensitivity by an internal amplifier circuit (not shown).

[0010] (4) is a speaker arranged in the front receiver (40 in FIG. 2) and used for talking to the ear,
The electric signal of the baseband section (3) amplified by the amplifier circuit (5) is converted into sound. The speaker (4) emits not only the reception sound but also a key click sound. As shown in FIGS. 3 and 4, the speaker (4) is arranged so that the sound output is emitted substantially in front. Reference numeral (6) denotes a microphone used for a telephone call, which is disposed in a transmitting section (60 in FIG. 2) on the front side and converts voice into an electric signal. (7) is an amplifying circuit, which amplifies the output of the microphone (6) and outputs it to the baseband unit (3). As shown in FIGS. 3 and 4, the microphone (6) is disposed so as to face substantially the front.

Reference numeral (8) denotes a speaker for allowing the received sound to be heard by the surrounding people. The speaker is provided in the receiving unit (80 in FIG. 5) on the rear surface, and as shown in FIGS. It is arranged so as to output almost at the back. Ear speakers (4)
And the opposite direction. The speaker (8) converts the electric signal of the baseband section (3) amplified by the amplifier circuit (9) into sound. The speaker (8) also sounds an incoming call notification.

Reference numeral (10) denotes a connection part, which includes an earphone (201) of the earphone microphone (20) and a microphone (20).
2) is connected. The connection section (10) detects whether or not the earphone microphone (20) is connected, and outputs the result to the control circuit (12).

A switching circuit (11) is a control circuit (described later) for connecting the three respective amplifier circuits (5), (7), (9) and the connection section (10) to the baseband section (3). 12)
ON / OFF by the control of. Note that these three amplifier circuits (5), (7), and (9) have fixed gains, and cannot change the receiving sound volume or the sensitivity of the microphone.
The control of the control circuit (1
The audio codec (32) of the baseband unit (3) performs the control under the control of (2).

Reference numeral (12) denotes a control circuit composed of a microprocessor. The ROM (1) stores an operation program.
Each part is controlled based on 3). (14) is a RAM for storing information necessary for the operation of the control circuit (12).

(15) is a liquid crystal display unit for displaying a telephone number and the like. (16) is a vibrator, which generates vibration at the time of an incoming call under the control of the control circuit (12).

Numeral (17) is an input means, which is a numeric keypad (171) for inputting a telephone number, a call key (172) for starting a call, and an end key (173) for ending a call. And a MON key (174) for producing a reception sound from the speaker (8) on the back. FIG.
As shown in (1), the MON key (174) is disposed on the left side, and the user can easily operate the MON key (174) even during a call. Reference numeral (18) denotes an LED, which notifies an incoming call or the use state of the speaker (8) on the back by lighting or blinking.

Next, the main operation of the present invention will be described. FIG.
Is a flowchart showing the operation of the control circuit (12). In FIG. 6, the ear speaker (4) disposed on the front is referred to as an ear speaker, and the speaker (8) disposed on the back is referred to as a back speaker. In FIG. 6, whether or not the speakers (4) and (8), the earphone (201), the microphones (6) and (202) are connected to the baseband unit (3) is indicated by ON / OFF. . For example, the fact that the ear speaker (8) is OFF means that the control circuit (12) controls the switching circuit (11), and the amplification circuit (5) for the speaker (4) and the baseband unit disposed on the front. This is to interrupt the connection of (3).

The control circuit (12) turns off the back speaker (8) as an initial state (S1). When the earphone microphone (20) is connected to the connection section (10) (Y in S2), the ear speaker (4) is turned off, and the microphone (6) disposed on the front is turned off. Turn on (201) and turn on the earphone microphone (20)
Is turned on (S3). If the earphone microphone (20) is not connected to the connection part (10) (N of S2), the ear speaker (4) is turned on, the microphone (6) arranged on the front is turned on, and the earphone ( 201) is turned off, and the microphone (202) of the earphone microphone (20) is turned off (S4).

In this state, when the MON key (174) is operated (Y in S5), the control circuit (12) checks whether the MON key (174) is pressed for one second or more (S5).
6). When pressed for one second or longer, the control circuit (12) causes the ear speaker (4) or the earphone (201) to output a key click sound once (S7). The LED is blinked at a predetermined cycle, and an icon indicating that the back speaker (8) is ON (monitoring state) is displayed on the display unit (15) (S8). Then, the back speaker (8) is turned on, the microphone (6) is turned off, and the microphone (202) of the earphone microphone (20) is turned off.
(S9). At this time, in step S3 or S4, the ear speaker (4) or the earphone (2)
01) is ON.

If the MON key (174) has not been pressed for one second or more in step S6, the control circuit (12) stops the blinking of the LED and the icon display on the display unit (15) in step S8 (S10). . Then, the back speaker (8) is turned off (S11). If the earphone microphone (20) is connected (Y in S12), the microphone (6) is turned off and the earphone microphone (2) is turned off.
0) The microphone (202) is turned on (S1)
3). If the earphone microphone (20) is not connected (N of S12), the microphone (6) is turned on, and the microphone (202) of the earphone microphone (20) is turned off.
F (S14).

As described above, the present invention provides an ear speaker (including an earphone) when a reception sound is transmitted by a speaker on the back side so that a weather forecast can be heard by surrounding people.
From the receiver.

The ON / OFF operation for determining whether or not to transmit the reception sound from the speaker on the back is distinguished by the time difference between long press and short press of a predetermined key.

In the above-described embodiment, the microphone is muted when the receiving sound is transmitted from the rear speaker. However, the present invention can be applied to a telephone device that does not mute the microphone. .

[0024]

As described above, according to the present invention, when the reception sound is transmitted from the back speaker (when monitoring), the reception sound is also transmitted from the ear sound output unit (speaker or earphone). The user can hear the reception sound with the sound output unit kept in his / her ear.

In the case where the ON / OFF display of the LED or the monitor of the display unit cannot be seen because the sound output unit is put on the ear, the present invention turns on the monitor by pressing the key long or short. / OFF, ensured ON
/ OFF operation can be performed. For example, the present invention differs from a telephone device in which an ON / OFF operation is performed every time a key is pressed.
A more reliable operation can be performed without looking at the display.
