First, it is assumed that the radio, CD, and TV in the present invention are selectively operated by the user by key manipulation using the key operation unit 120 or the remote control 200.

Figures 2a and 2b shows the operating relationship of the present invention for the case of a telephone call during the operation of radio, CD, TV, respectively, Figure 2a when there is no call recording function, Figure 2b shows the operation when the call recording function It is shown.

In the case of not having a call recording function in the telephone, when the power is turned on and the device of the present invention is activated, the telephone circuit unit 20 always detects a ring signal by ring signal detecting means (not shown). Step 1)

If a call is made through the trunk line, the ring signal is detected by the ring signal detection unit (not shown) to signal the switching unit 90.

The switching controller 111 determines whether at least one device of the radio, CD, or TV is in operation (Step 2), and when it is in operation, mutes the operating device through the switching operation of the switching unit 90. (Step 3) The ring signal is output through the speaker unit 150 (Step 4).

The user turns on (Step 5) the call button (not shown in the drawing) installed in the key control unit 120 or the remote control 200, or presets (eg, 'hello') through the microphone 22. If you input voice (Step 6), the call is connected (Step 7).

After the phone call, the user turns on the end button (not shown) (Step 8) or inputs a preset voice (for example, 'end call') through the microphone 22 (Step 9). The call is terminated (Step 10), and the switch of the switching unit 90 is switched by the switching control unit 111 to release the mute state of the muted device (Step 11).

In the case of having a call recording function inside the telephone, when the power is turned on and the device of the present invention is activated, the telephone circuit unit 20 always detects a ring signal by ring signal detecting means (not shown) (Step). 1)

If a call is made through the trunk line, the ring signal is detected by the ring signal detection unit (not shown) to signal the switching unit 90.

The switching controller 111 determines whether at least one device of the radio, CD, or TV is in operation (Step 2), and when it is in operation, mutes the operating device through the switching operation of the switching unit 90. (Step 3) The ring signal is output through the speaker unit 150 (Step 4).

The user turns on (Step 5) the call button (not shown in the drawing) installed in the key control unit 120 or the remote control 200, or presets (eg, 'hello') through the microphone 22. If you input voice (Step 6), the call is connected (Step 7).

If a user wants to record a call during a call, turning on the record button (not shown) (On) (Step 100) records the call (Step 101), and turns off the record button (Step 102). Recording ends (Step 103).

After the phone call, the user turns on the end button (not shown) (Step 8) or inputs a preset voice (for example, 'end call') through the microphone 22 (Step 9). The call is terminated (Step 10), and the switch of the switching unit 90 is switched by the switching control unit 111 to release the mute state of the muted device (Step 11).

That is, in this case, the operation of steps 100 to 103 is further included between the operation steps Step 7 and Step 8 when the call recording function is not provided.

3A illustrates an operation relationship when a user inputs and stores a message when necessary, and when the user turns on a recording button installed in the key control unit 120 or the remote controller 200 (Step 21), the switching control unit ( 111 determines whether at least one device of the radio, CD, or TV is in operation (Step 22), and when the device is in operation, mutes the operating device through the switching operation of the switching unit 90 (Step 23). The voice message is stored in a memory (not shown) in the message circuit unit 30 (Step 24).

After the recording is finished, if the user turns off the recording button (Step 25), the voice message storage is terminated (Step 26), and the switching unit 90 is switched and muted by the control of the switching control unit 111. Release the mute state (Step 27).

3B illustrates an operation relationship for reproducing the message stored by FIG. 3A. When the user turns on a playback button (not shown) installed in the key control unit 120 or the remote controller 200 (Step 31), The switching controller 111 determines whether at least one device of the radio, CD, or TV is in operation (Step 32), and when the operation is in operation, mutes the operating device through the switching operation of the switching unit 90. (Step 33) The voice message is reproduced from a memory (not shown) in the message circuit unit 30 (Step 34).

If it is determined that the play button is Off (Step 35), if it is turned off, the play operation is terminated and the ring signal is not received by the ring signal detecting means (not shown in the drawing) because a call is made during the play operation. If it is detected (Step 36), the control of the switching control unit 111 is switched by the switch of the switching unit 90, the playback of the voice message is paused (Step 37) and the call is connected (Step 38), the call is terminated ( Step 39), the switch of the switching unit 90 is switched by the control of the switching control unit 111, so that reproduction of the stored message is continued.

4A illustrates the operation of the security circuit unit at the time of emergency signal reception. When an emergency signal transmitted from a neighboring house is received through the RF transmission / reception circuit unit 41 (Step 41), the security circuit unit 40 detects the signal from the security data detection unit. It is transmitted to the 114 and determines whether at least one or more of the radio, CD, TV is operating under the control of the switching control unit 111 (Step 42), the switching operation of the switching unit 90 to the operating device Mute through (Step 43), and outputs the alarm signal through the speaker unit 150 (Step 44), and then to mute the muted device (Step 45).

4B illustrates the operation of the security circuit unit at the time of emergency signal transmission. When an emergency situation is detected by the security data detection unit 114 (Step 51), at least one of a radio, a CD, and a TV is controlled by the control of the switching control unit 111. It is determined whether at least one device is in operation (Step 52), and the operating device is muted through the switching operation of the switching unit 90 (Step 53), and an alarm signal is transmitted through the speaker unit 150. After outputting (Step 54), turn on the RF transmission switch (not shown) installed in the key control unit 120 or the remote control 200 (Step 55) to transmit an emergency signal to the neighboring house (Step 56), the muted device Cancel the mute state (Step 57).
