example, the sound pressure level at the position of the microphone can be set to output only the
sound having a predetermined value or more from the speaker. You may want to give a voice to
your family in another room, but you can use it if you do not want it to be heard in the other
room, for example, a sound with a sound pressure level of 60 dB or more at the microphone
position. Sets the speaker to output less than 60 dB of sound, so a relatively small voice, eg, a
voice spoken on the phone, is not output from the speaker, but a relatively large voice, eg, to a
family The call can be output from the speaker.
[0079]
(2) Also, conversely to this, the control device 24 may be provided with a limiter so that the
speaker does not output a sound higher than a preset sound pressure level.
[0080]
(3) By setting the control device 24 so that only the voice of a person registered in advance (for
example, the voiceprint of a family member) can be output from the speaker, sounds other than
the voice of the person registered in advance (here So that extra noise can not be heard from the
speaker.

For example, by registering the voices of the infant and the care recipient, the voice of the infant
and the care recipient can be easily transmitted to the family.
[0081]
Although the sound collected from the microphone contains both human voice and ambient
noise, the control device 24 capable of such a thing can make the noise component out of the
sound signal obtained from the microphone. A voice extraction circuit (registered voice pass filter
of the present invention) that can be removed may be provided. The voice extraction circuit
includes a voiceprint analysis circuit that analyzes human voice, a voiceprint memory that stores
voiceprints analyzed by the voiceprint analysis circuit, and a comparison that extracts human
voice by comparing with voiceprints that store sound signals from microphones. It is sufficient if
a filter or the like is provided.
[0082]
As the operation, first, the voiceprint registration of the person who wants to register is
performed. The voice of the person to be registered is collected by any of the microphones, and
the sound signal from the microphone is input to the voiceprint analysis circuit of the voice
extraction circuit. The voiceprint analysis circuit analyzes the voiceprint of the collected person
and stores the result in voiceprint memory. After voiceprint registration is completed, the voice
of the person and surrounding noise are collected by the microphone, their sound signals are
input to the comparison filter of the voice extraction circuit, and voiceprint information of the
person registered from voiceprint memory at any time in the comparison filter. Is input, and from
this information, only the voice of the registered person is extracted from the signals input from
the microphone and is output to the speaker.
[0083]
As a result, from the speaker, the surrounding noise is removed and only the voice of the
registered person is output, so that the voice of the person becomes easy to hear.
[0084]
(4) Also, conversely, by setting the control device 24 so that the voice of the person registered in
09-05-2019
20
advance is not output from the speaker, the voice of the person registered in advance can not be
heard. You can also
For example, by registering a child's voice, it can be set so that the child's voice can not be heard.
(5) The voice of the family may be registered in the control device 24, and sounds other than the
voice of the family may not be output from the speaker. This allows the family voice to be
transmitted but not the other noises.
[0085]
(6) The frequency (for example, 63 Hz or less) of the walking sound in the building is registered
in the control unit 24 in advance, and in the monitoring mode, the sound in the frequency range
registered in advance is set in the control unit 24 in advance. If the control device 24 determines
that the level is higher than the stored level, it can also be determined that the intruder is
walking in the building, and it is also possible to detect the intruder from the sound in the room.
Thus, when an intruder is detected, it is possible to automatically switch the device such as the
electric lock to the alert mode without pressing the emergency button or speaking a keyword.
[0086]
(7) The frequency (for example, 125 Hz or less) of the falling sound when a person falls in the
building is registered in advance in the control device 24, and the sound in the frequency range
registered in advance is set in the control device 24 in advance. If the control device 24
determines that the level is equal to or higher than the stored level, the warning sound set in
advance in the control device 24 may be output from the speaker, for example, causing the fall of
the care recipient to occur earlier to the other family. It also makes it possible for family
members to rush to the care recipient.
[0087]
(8) As walking noise and falling noise travel through the air in the air and enter the microphone,
small walking noise may not be picked up by the microphone.
In such a case, if a vibration detection sensor having the same structure as the microphone is
directly attached to the floor and the vibration detection sensor is connected to the control
09-05-2019
21
device 24, walking noise and falling noise can be detected with high sensitivity. .
[0088]
(9) In addition to the footsteps, frequency bands such as broken sound of glass and sound to
open the door key are registered in the control device 24 in advance, and the sound in the
frequency band registered in advance is the control device If the control unit 24 determines that
the level is equal to or higher than the level set to 24, it can also be determined that the glass is
broken or that the door is about to be unlocked. Mode can be switched from the normal mode to
the alert mode, or can be reported to a security company.
[0089]
(10) A clock or timer may be incorporated in the control device 24 to switch the system mode at
a preset time.
Thus, for example, the system can be automatically set to the normal mode during the day and
the monitoring mode during the night.
[0090]
(11) Each room is provided with an infrared sensor that detects infrared radiation emitted from
the human body, and when the infrared sensor detects infrared radiation emitted from the
human body, the system mode is changed to alert mode or a warning is issued. It is also possible.
For example, when sleeping at night, if the detection of the infrared sensor in the room where the
person is sleeping is off and the detection of the infrared sensor in the room where there are no
people, it is possible to detect intruders in the room where there are no people. The sound of the
speaker makes it possible to sense the presence of the intruder.
[0091]
(12) In the above embodiment, the system has set two modes, the normal mode and the
monitoring mode, but other modes of processing of the electric signal may be further set. In the
above embodiment, the monitoring mode is a mode in which the electric signals from the
09-05-2019
22
microphones 22A to 22D are amplified at a preset amplification factor and output from the
speaker, and the amplification factor is constant regardless of the frequency. It is sufficient if the
processing of the electrical signal is different for at least another mode, so that processing of the
electrical signal may be performed so that sound in a part of the frequency range is not output,
or sound is output from the speaker It is good. That is, in all modes, an audio signal processing
circuit may be interposed between the microphone and the speaker.
[0092]
(13) When detecting a pre-registered sound, the control device 24 may be set to contact a preregistered telephone or personal computer, etc. from outside using a mobile telephone, personal
computer etc. It may be set to be connectable to the control device 24. In this way, it is possible
to know the abnormality of the non-residential home on the mobile phone, PC or the like outside
the home, and to hear the sound of the non-residential home. Furthermore, when leaving the
family and leaving, etc., it is also possible to listen to the inside of the house from outside with a
mobile phone, a personal computer, etc.
[0093]
(14) In the above embodiment, a plurality of speakers are installed in one room, but in the
present invention, it is sufficient if at least one speaker is installed in the room.
[0094]
(15) In the above embodiment, an example in which a microphone and a speaker are arranged in
each of the first room 12, the second room 14, the third room 16, and the fourth room 18 is
shown. Although the stairs, the bathroom, the washroom, the toilet, and the like are not
described, a microphone and a speaker may be provided for these as well as the first room 12 to
the fourth room 18 as necessary.
