Abstract

<P>PROBLEM TO BE SOLVED: To provide an automatic silencer or muting system in which a sound output means of an acoustic device enters into a silent state or a mute state during a phone call or communication. <P>SOLUTION: An incoming signal or an incoming tone is recognized, the state of a hook switch of a telephone set for confirming the lifting/setting of the receiver is further recognized, and the sound of the acoustic device is turned off or turned down on the basis of the results. <P>COPYRIGHT: (C)2004,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to mute or faint sound of an audio device having a voice output means and the state of a telephone.

[0002]

2. Description of the Related Art A sound device having a sound output means means an audio system in a broad sense such as a television or a stereo device. In the living room or office, the audio device and the telephone are located close to each other, and the sound of the audio device is so loud that it is often difficult to hear the ringing tone or call sound of the telephone.

In such a case, in order to make it easier for a person near the acoustic device or a person who receives a telephone call to hear the call sound,
It is customary to turn off the audio device or turn down the volume of the audio device.

[0004]

However, during a call, even if the sound of the audio device is loud, the sound cannot be reduced because the user is talking, or the sound of the audio device is too loud to disturb the conversation. The problem is that you may not even hear the ringtone of the phone.

[0005]

[Means for Solving the Problems] Therefore, when a telephone call is in progress, when a ring tone is sounding, or when a signal for an incoming call is issued, the sound of an audio device nearby is automatically generated. The above problem can be solved by eliminating or reducing.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention includes an incoming signal discriminating device which is inserted into a telephone line to discriminate an incoming signal, a hook switch discriminating device which discriminates a state of a hook switch of a telephone connected to the telephone line, It is composed of a telephone set, a muffler device that operates based on the states of the incoming signal discrimination device and the foot switch discrimination device, and an audio device having voice output means separately from those telephones, or A ring tone recognition device for recognizing, a hook switch determination device for determining the state of a hook switch of a telephone, the telephone, a muffling device that operates based on the states of the ring tone recognition device and the hook switch determination device, and those In addition to the telephone, the audio device has a voice output means.

[0007]

FIG. 1 (Embodiment 1) is a connection diagram of an embodiment of the present invention, in which the polarity of a telephone line (7) is reversed during an incoming call. Therefore, the incoming signal discrimination device (3) inserted between the telephone lines (7) can recognize that the incoming call is being made. Further, the hook switch determination device (1) can determine whether the handset is up or placed by determining whether the hook switch of the telephone (2) is ON or OFF.

Therefore, by checking the states of the incoming signal discrimination device (3) and the hook switch discrimination device (1),
It is possible to recognize from the time when an incoming call is made until the handset goes up, the call ends and the handset is placed. Therefore, the period is transmitted to the muffling (weak sound) device (4), and the muffling (weak sound) device (4) mutes or weakens the sound of the acoustic device (5).

In the embodiment of FIG. 2 (embodiment 2), a ring tone recognition device (6) is used in place of the ring signal discrimination device (3) shown in FIG. (Built-in ring tone recognition device) to detect. After that, the idea is the same as in FIG. As shown in FIG. 2, by confirming the states of the ring tone recognition device (6) and the hook switch discrimination device (1), it is possible to recognize the period from when an incoming call is being made until the handset is picked up and the call ends and the handset is placed. it can. Therefore, the period is transmitted to the muffling (weak sound) device (4), and the muffling (weak sound) device (4) mutes or weakens the sound of the acoustic device (5).

[0010]

As described above, the automatic silencing (weak sound) system of the present invention has the following effects. 1 Even if the sound device is loud, the sound device does not emit a sound or makes a low sound between the ringing tone of the telephone and the hang up of the telephone, which disturbs the telephone call. Absent. 2 It is especially convenient when an important customer calls from a telephone installed in the company cafeteria (where music etc. is ringing). 3 It is convenient to call when you are alone in the office or home.

[Brief description of drawings]

FIG. 1 is an explanatory diagram showing a method of implementing an automatic muffling (softening) system. (Embodiment 1) 1 has a function of recognizing an ON / OFF state of a hook switch of a telephone 2 by a hook switch discriminating device and notifying a muffling (silent) device 4 of the same. Reference numeral 3 denotes an incoming signal discrimination device, which has a function of recognizing that an incoming call is being received by the telephone of 2 and contacting the muffling (quiet) device of 4. Reference numeral 4 denotes a sound deadening device, which has a function of muting or reducing the sound of the acoustic device 5 based on the signals from 1 and 3.

FIG. 2 is an explanatory diagram showing a method of implementing an automatic muffling (softening) system. (Embodiment 2) 1 has a function of recognizing an ON / OFF state of a hook switch of a telephone 2 by a hook switch discriminating device and contacting a muffling device 4 of a sound. Reference numeral 6 is a ringtone recognizing device, which has a function of recognizing that an incoming call is being received by the telephone of 2 and contacting the muffling (silent) device of 4. Reference numeral 4 denotes a sound deadening device, which has a function of muting or reducing the sound of the acoustic device 5 based on the signals from 1 and 6.
