Description

Infrared Mute Device and Method in Telephone

The present invention relates to a telephone, and more particularly, to a method of muting a device capable of adjusting a volume using a remote controller using infrared rays during a telephone call.

In general, the volume of a television, a radio, an audio, etc. can be adjusted by using a volume control key installed in a key panel or a volume control key of a remote controller.

Therefore, when a call is received while using the TV, radio, or audio, the user has to mute the sound using the key panel or the remote controller and then talk on the phone. In other words, when a call comes while watching or listening to TV, radio, audio, etc., there is an inconvenience in that the user directly adjusts the volume to decrease or mute separately.

Accordingly, an object of the present invention for solving the above problems is to provide a telephone having a device for generating an infrared signal for muting when a specific key is pressed.

Another object of the present invention is to provide a method for muting the sound using a telephone.

1 is a block diagram of a mute device using infrared light in a telephone according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, briefly described the infrared communication applied to the present invention.

Infrared communication means to convert a signal to be transmitted into a pulse and then transmit an infrared signal generated by the pulse, receive the transmitted infrared signal, and convert the pulse generated by the received infrared signal into an original signal. It is a communication method. The infrared communication method is mainly used in a remote control for controlling electronic products and the like at a long distance.

As shown in FIG. 1, the mute device using the infrared light of the telephone according to the present invention includes a mute switch 20, an infrared diode D1, and a controller 10. In addition, the infrared signal receiving apparatus of the television is composed of an infrared diode D2, a control unit 30, and a volume control unit 40.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the above-described configuration.

A user picks up a handset and starts a call when a call comes in while watching or listening to television, radio, audio, and the like.

At this time, the mute switch 20 of the transmitting side corresponding to the telephone is switched, and the switch signal is input to the controller 10 by the switching of the mute switch 20. The mute switch 20 is switched in conjunction with a hook switch (not shown in the drawing) which is operated by a user pressing a specific key corresponding to the mute key or by hearing a handset. The specific key may be used by using a key provided in the conventional telephone or by further providing a separate key.

When the switch signal is applied, the controller 10 determines that the signal is a mute request and outputs the pulse signal corresponding to the mute request. When the pulse signal is output, the infrared diode D1 is turned on / off by the pulse signal to generate an infrared signal.

The D1 is turned on when the pulse signal is at the low level, and turned off when the pulse signal is at the high level. At this time, the pulse signal generated by the control unit 10 uses the same signal as the pulse signal used in a typical remote control for controlling a television.

The infrared signal generated by the telephone is received through the receiver D2. The D2 generates a pulse signal in the presence or absence of the infrared signal. The generated pulse signal is applied to the control unit 30 as the same pulse signal generated by the control unit 10 of the phone, and the control unit 30 converts the applied pulse signal into a volume control signal and outputs it. The volume control signal is applied to the volume control unit 40 to adjust the mute state to block the sound.

As described above, by applying the present invention, when a telephone call is received while watching a television, the telephone can be used to mute the sound of a television, a radio, an audio, etc., thereby effectively blocking the volume during the telephone call.
