In particular, a terminal device in the form of a headset is configured to perform an audio output function and a function of the terminal device in parallel, so that an external call signal arrives while listening to music. The present invention relates to a headset-type terminal device having an audio output function of a communication system that enables switching between an audio function and a terminal function by a simple button operation when a call signal is to be made or an external call signal is issued.

In general, a terminal device of a communication system is located at one end of a subscriber line to receive a call signal of a counterpart transmitted through an exchange system and perform voice or data communication when the subscriber responds to the call signal. In addition, when the subscriber operating the corresponding terminal calls the other party, the reverse operation is performed. When the unique identification number such as the telephone number of the called terminal is transmitted to the switching system, the switching system receiving the signal is received. When the other party answers by calling the other party's terminal, the call is performed.

As a terminal device of a communication system that performs the above functions, the terminal is fixedly operated at a predetermined position and a handset designed to enable wireless communication with the terminal to secure mobility within a predetermined distance range. have. In particular, since the handset is mobile, the subscriber can receive the call signal of the terminal or issue the call signal to the counterpart within a certain distance limit.

Referring to the operation of the device according to such a configuration as follows.

The headset-type terminal according to the present invention is provided with two connection parts for transmitting and receiving signals. The two connecting portions are a line connecting portion 21 for connecting subscriber lines and an audio connecting portion 22 connected to an audio device. The terminal operates differently depending on whether the subscriber line and the audio are connected.

First, when an audio device is not connected to the audio connection unit 22 and only the subscriber line is connected to and operated by the line connection unit 21, the call signal issued from the other side is input / output signal through the line connection unit 21 connected to the subscriber line. It is received by the switching unit 23. At this time, the input / output signal switching unit 23 transmits a ring signal sound to the call control unit 23C through the line interface unit 23C.

When the ring tone is output from the input / output signal switching unit 23, the call controller 25 determines whether to display the incoming call or automatically switch to the call mode. At this time, the call mode switching is automatically switched when the angle sensor unit 23A notifies the state of the headset mounting, and when the headset is not mounted, the incoming call is displayed through the incoming display unit 25C and the button input unit 25D is monitored. The terminal operator detects whether the call mode button is turned ON. Thus, when the operator switches the call mode button to ON or the automatic switching is performed by the main control unit 25A, the operator operates in the call mode so that the voice signal of the other party received through the subscriber line is output to the receiver 24, The transmitter 26 is activated to transmit a voice signal issued by the operator to the counterpart through the subscriber line.

When the operator wants to make a call, the operator switches the call mode button to ON, receives the ringback tone of the subscriber line, and dials the telephone number of the other party through the button input unit 25D. The dialed telephone number is transmitted to the switching system through the line connection unit 21, and if there is a response from the other party, the call connection is established and the transmitter 26 is activated. 23B) outputs the voice of the other party to the receiver 24.

When the other end of the call in the state of the call connection as described above, the busy tone on the subscriber line (Busy Tone) is detected by the tone detection unit 25E to recognize the end of the call to terminate the call mode. When the operator detaches the headset to end the call first or switches the call mode button to OFF, the operator recognizes the angle by the angle sensor unit 23A and the button input unit 25D, respectively, to terminate the call mode. When the call mode ends, the receiver switching unit 23B resets the path so that the input signal of the audio connecting unit 22 can be output to the receiving unit 24.

On the other hand, when the audio connection unit 22 and the line connection unit 21 are connected to the audio device and the subscriber line, respectively, and the audio output is performed through the receiver unit 24, the operation is different from the above-described operation. That is, when there is a call of the other party while the operator is listening to the music, when the ring signal detection unit 25B detects the ring signal tone, the main control unit 25A automatically switches to the call mode, whereby a response is possible. If you want to make a call signal while listening to the call is possible by switching the call mode button to ON.

After the switch to the call mode is the same as the operation of the call mode described above, when the call is terminated, the music that was heard before switching to the call mode is output again through the receiver 24. In other words, even when the call is received or the call is made while listening to the music, the music is automatically output without a separate switching operation after the call operation is completed.

As such, the present invention implements a headset-type terminal having an audio output function and listens to music and automatically switches to a call mode when a call signal is received. When the automatically switched call mode ends, the audio output is resumed. It is done.

While the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Therefore, the above description does not limit the scope of the present invention defined by the limits of the following utility model registration claims.

As described above, the headset-type terminal device having an audio output function of the communication system according to the present invention is automatically switched to a call mode when a call signal is received even while wearing a headset to listen to music. The phone can be answered without the operation of the phone and after the call is terminated, the audio output function is automatically switched to listen to music, thereby improving the time management efficiency of modern people.

In other words, you can receive and make phone calls while doing other things, which can give users a lot of convenience. Especially, people who do a lot of work other than sending / receiving personal calls for a long time while wearing a headset such as home PC users or attendants Has the effect of increasing the convenience of the terminal operation.
