  output from the audio circuit portion 100.

  We will now describe in detail the operation of the audio system 60 in accordance with the first preferred embodiment of the present invention. Referring first to FIG. 4, the switching part 130 being in the state indicated above, if a telephone call is applied by a party located outside, the call signal is delivered by the part forming telephone circuit 110 so that the call signal detector 140 receives the call signal and delivers a signal corresponding to the controller 150 during step S100. Then, in step S102, the controller 150 delivers the first control signal CTL1 to the switching part 100 so that the output signal from the audio circuit part 100 is interrupted. That is to say that under the effect of the delivery of the first control signal CTL1 to the switching part 130, the first mobile contact point 131c of the first switch 131 is connected to the secondary contact point 131b of this switch , and the second movable contact point 132c of the second switch 132 is connected to the secondary contact point 132b of this switch so that an output of the adjacent circuit part by means of the speakers 170 and 170 'is not audio system 60 is switched to a muted state.

In this state, the call signal is delivered by the telephone circuit part 110 via the first and second speakers 170 and 170 'in the form of a telephone ringing by means of the telephone part.

switching 130, at step S103.

  To answer the phone, the user presses a button to lift the input part 50 or utters a word or a phrase fixed in advance, such as for example "answering the phone". Consequently, the controller 150 receives a signal when the pick-up button is pressed during step S104 or an input signal from the voice command to answer the telephone, during a step S105, after which the controller 150 establish a

  communication between the caller and the user

  speaker using speakers 170 and 170 'and microphone 40 in step S106. That is, the controller 150 connects a telephone call line in

  the part forming the telephone circuit 110.

  During the telephone conversation, the user

  author may wish to save directions, number

  phone, etc. provided by the caller.

  In this case, the user presses the recording button of the input part 50 so that the controller 150 receives a corresponding signal during step S107. Therefore, the controller 150 transmits a recording command (W) to the recording part 120 so that the latter stores the output signal of the

  part forming telephone circuit 110 at step S108.

  During the recording of the output signal of the telephone circuit portion 110, the voice of the caller continues to be delivered from the speakers

and 170 '.

  Then, when the user wishes to interrupt

  recording, he presses the recording button again

  input part 50 to stop recording so that the corresponding signal is received by the controller

  150 in step S109. The controller 150 then sends a signal to the recording part 120

  to interrupt the recording during step SllO.

  After step S106 which consists of establishing communication between the user and the person calling or after step S110 which stops recording, to end the telephone conversation, the user presses the off-hook button on the input part 50 or pronounces a word or a sentence fixed in advance to interrupt the telephone conversation, such as for example "hanging up the telephone". As a result, the controller receives a corresponding signal from the input part 50 during step S111 or from the speech recognition part 160 during step S112, then disconnects the telephone call line in the circuit part 110, so that the connection with the telephone line is interrupted during step S113. Then, in step S114, the controller 150 sends the first control signal CTL1 to the switching part 130 so that the first mobile contact point 131c of the first switch 131 is connected to the primary contact point 131a of this switch and that the second mobile contact point 132c of the second switch 132 is connected to the primary contact point 132a of this switch, which has the effect of reconnecting the audio circuit part 100 to the speakers 170

and 170 '.

  In the above, we listened simultaneously to the output signal from both the audio circuit part 100 and the telephone circuit part 110, the user presses a button located in the input part 50 to facilitate this control so that the controller 150 sends the first control signal CTL1 to the switching part 130. Consequently, the first movable contact point 131c of the first switch 131 is connected to the primary contact point 131a of this switch so that the output of the forming part

  audio circuit 100 is carried out via the built-in

  left speaker 170, and that the output of the telephone circuit portion 110 is achieved by means of the

170 'right speaker.

  Referring now to FIG. 5, when the user wants to record a message so that it can be listened to by other people, or else can record information that the user wishes to remember, he actuates a record button of messages from the input part 50 so that a corresponding signal is transmitted to the controller 150 during step S115. Then, in step S116, a determination is made as to whether the audio circuit part 100 delivers its output signal through the speakers 170 and 170 'and, if so, the controller 150 sends the second signal command CTL2 to the switching part 130 so that the output signal of the audio circuit part is muted and does not interfere with the recording of the message in step S117. With the delivery of the second control signal CTL2 to the switching part 130, the third mobile contact point 133c of the third switch 133 is connected to the primary contact point 133a of this switch, and the fourth contact point 134c of the fourth switch 134 is connected to the primary contact point 134a of this switch, which has the effect of interrupting the output signal delivered by the

audio circuit part 100.

  The controller 150 then issues the recording command (W) to the recording part 120 so that a message can be recorded in the recording part 120 via the microphone 40 during step S118. Furthermore, when the user has finished his registration, he presses the registration button of the input part 50 so that a corresponding signal is sent to the controller 150 during step S119. The controller 150 then sends a stop command to

  the recording part 120 to stop the recording

  ment of the message in step S120. During this step, the control device 150 again delivers the second control signal CTL2 to the switching part 130 to reconnect the output of the audio circuit part

  to speakers 170 and 170 ', in step S121.

  Referring now to the flowchart of Figure 6, to listen to the message recorded during a telephone conversation or recorded by the user, the user presses a button for reading the input part 50 so that a corresponding signal is transmitted to the controller 150 during step S122. Therefore, the controller 150 outputs the second control signal CTL2 to the switching part 130 so that the output signal from the audio circuit part 100 is muted and the recording part is connected to the speakers 170 and 170 'during step S123. That is to say that, under the effect of the sending of the second control signal CTL2 to the switching part 130, the third mobile contact point 133c of the third switch 133 is connected to the primary contact point 133a of this switch, and that the fourth mobile contact point 134c of the fourth switch 134 is connected to the primary contact point 134a of this

switch.

  Following step S123, the controller 150 sends a read command (R) to the recording part so that the recorded message is delivered via the speakers 170 and 170 'in step S124. During the display of the message stored in the recording part 120, the telephone call is sent by an outside person, the call signal detector 140 detects this call and sends a signal corresponding to the controller 150 during step S125. As a result, the controller 150 sends a read stop command to the recording portion 120 to stop the

  reading of the message during step S126.

  Then when the user presses the hook button located in the input part 50 or pronounces a word or a phrase fixed in advance such as for example "answer the telephone", the controller 150 receives a corresponding signal respectively during step S127 or S126, after which the controller 150 establishes communication between the caller and the user through the use of speakers 170 and 170 'and microphone 40 during step S129. That is, the controller 150 connects a telephone call line in the telephone circuit part 110 and sends the first and second control signals CTL1 and CTL2 to the switching part 130 to modify the connection in this part so the output signal from the part

  forming telephone circuit 110 is issued by the loudspeakers

  speakers 170 and 170 'and that the caller and the user can have a telephone conversation using the speakers 170 and 170' and the microphone 40. Following step S129, to stop the telephone conversation, the user presses the off-hook button of the input part 50 or pronounces a word or a phrase fixed in advance to stop the conversation

  telephone, such as "hanging up the phone".

  As a result, the controller 150 receives a corresponding signal from the input part 50 during step S130 or the speech recognition part 160 during step S131, then disconnects the telephone call line in the circuit part telephone so the connection with the telephone line

is interrupted during step S132.

  Then in step S133, the second control signal CTL2 is transmitted to the switching part 130

  to reconnect the recording part 120 to the loudspeakers

  speakers 170 and 170 ', and the controller 150 again sends the read command (R) to the recording part 120. When the message has been completely displayed, a corresponding signal is sent to the controller 150 in step S134. Therefore, the controller 150 sends the stop read command to the recording portion

  to stop the display of the message during step S135.

  Then, the controller 150 sends the first and second control signals CTL1 and CTL2 to the switching part to reconnect the audio circuit part 100

  to speakers 170 and 170 'during step 136.

  The intercom circuit portion 220 is connected to the secondary contact point 234b of the fourth switch 234. In addition, the third secondary contact point 233c of the third switch 233 is connected to the left speaker 270, and the fourth point of movable contact 24c of the fourth switch 234 is connected to the right speaker 270 '. The third switch 233 is controlled by the second control signal CTL2 delivered by the controller 255, while the fourth switch 234 is controlled by the third control signal CTL3 delivered by the intercom circuit portion 220. Since the third switch 233 has only two contact points 233a and 233c, this switch is controlled only in

closed and open states.

  In the audio system 60 of the present invention structured as indicated above, if the first mobile contact point 231c of the first switch 231 is connected to the primary contact point 231a of this switch, the second mobile contact point 232c of the second switch 232 thus that the second primary contact point 232a of this switch, if the third contact point 233c of the third switch 233 is connected to the primary contact point 233a of this switch and if the fourth mobile contact point 234c of the fourth switch 234 is connected to the primary contact point 234a of this switch, the audio circuit part 200 delivers an output signal by the right and left speakers 270 and 270 ′ (assuming that the user has manipulated the input part 50 to music delivery). Unless a control signal is received from the controller 250 or the intercom portion 220, the switching portion 230 retains its connection configuration such that the audio system 60 is maintained in a state allowing the output signal to be delivered over there

audio circuit part 200.

  The operation of the audio system 60 according to the second preferred embodiment of the present invention will now be described in detail, with reference to FIGS. 8a, 8b and 9, which represent flowcharts used to describe the operation of the audio system 60 in accordance with the second form of

  preferred embodiment of the present invention.

  Referring first to Figures 8a and 8b, the switching part 230 being in the state indicated above and the user listening to music, if a telephone call is made by a person from outside, the signal the call is issued through the telephone circuit portion 210 so that the call signal detector 240 receives the call signal and sends a signal corresponding to the controller 250 in step S200. Then, in step S202, the controller 250 delivers the first control signal CTL1 to the switching part 230 so that the output signal from the audio circuit part 200 is interrupted. That is to say that under the effect of the sending of the first control signal CTL1 to the switching part 230, the first mobile contact point 231c of the first switch 231 is connected to the secondary contact point 231b of this switch and that the second mobile contact point 232c of the second switch 232 is connected to the secondary contact point 232b of this switch so that the signal output from the audio circuit part 200 supplied via the speakers 270 and 270 'is not possible and the audio system 60 has gone into a deafening state. Simultaneously, the third mobile contact point 232c of the third switch 233 is maintained in a state in which it is in contact with the primary contact point 233c of this switch (the third switch 233 is kept closed) and the fourth mobile contact point 234c of the fourth switch 234 is maintained in a state in which it is in contact with the primary contact point 234a of this switch. In this state, the call signal is delivered by the telephone circuit part 210 by means of the first and second loudspeakers 270 and 270 ′ as a telephone ringing signal via the telephone part.

switching 230 during step S203.

  To answer the phone, the user presses a button to lift the input part 50 or pronounces a word or a phrase fixed in advance, for example "answering the phone". Consequently, the controller 250 receives a signal to press the off-hook button in step S204 or a signal from the input of the voice command to answer the telephone in step S205, after which the controller 250 establishes a communication between the caller and the user using speakers 270 and 270 'and the microphone 40 in step S206. That is, the controller 250 delivers a signal to the telephone circuit part 210 to connect a telephone call line in this telephone circuit part. To interrupt the telephone conversation, the user presses the off-hook button on the input part 50 or utters a word or a phrase fixed in advance to stop the telephone conversation, for example "hanging up the telephone". It follows that the controller 250 receives a corresponding signal from the input part 50, in step S218, or from the voice recognition part 260 in step S219, then disconnects the telephone call line in different circuits telephone 210 so the connection with

  the telephone line is interrupted during step S220.

  Then, in step S221, the controller 250 sends the first control signal CTL1 to the switching part 230 so that the first movable contact point 231c of the first switch 231 is connected to the primary contact point 231a of this switch and that the second mobile contact point 232c of the second switch 232 is connected to the primary contact point 232a of this connector, which has the effect of reconnecting the audio circuit part 200 to the speakers 270

and 270 '.

  In the above, to simultaneously listen to the output signal from both the audio circuit part 200 and the telephone circuit part 210, the user presses a button located in the input part 50 to facilitate this control, so that the controller 250 delivers the first control signal CTL1 to the switching part 230. This is why the first movable contact point 231c of the first switch 231 is connected to the primary contact point 231a of this same switch so that the signal output from the audio circuit portion 200 is effected through the secondary speaker 270, and the signal output from the telephone circuit portion 210 is obtained by

  through the right speaker 270 '.

  However, following step S206 of connection of the telephone call line, if the user does not press the off-hook button or applies a voice command to hang up the telephone respectively in steps 218 and 219, and if an intercom call button 70, which is provided in an auxiliary intercom device (not shown) mounted at another location and connected to the intercom circuit part 220, the intercom circuit part 220 sends the third control signal CTL3 to the fourth switch 234 of the switching part 230 during step S216. As a result, the fourth mobile contact point 234c of the fourth switch 234 is connected to the secondary contact point 234b of this same switch so that an intercom call ringtone is delivered by the right speaker 270 ' in step S208. At this point, communication with the person who

  calls is still possible through the built-in

speaker 270.

  Then, if the user presses the hold button on the input part 50, a corresponding signal is transmitted to the controller 250 during step S209A. Therefore, the controller 250 sends a second control signal CTL2 to the third switch 233 to cause the opening of the latter, which places the output of the telephone circuit part 210 on standby

in step S210.

  Then, if the user presses an intercom communication button located in the input part, a corresponding signal is sent to the part forming the intercom circuit 220 during step S211. Consequently, an intercom line in the intercom circuit part 220 is opened so that the user can communicate with a person present at the door or at another location during step S212. That is, using a microphone and a speaker provided in the intercom auxiliary device, and the right speaker 270 'and the left speaker and microphone 40 in the system audio 60 communication between user and person at device level

  intercom auxiliary is possible.

  Following the step indicated above, if the user has ended the conversation with the intercom,

  he presses the communication button on the inter-

  phone. Therefore a corresponding signal is sent to the intercom circuit part 220 so that the intercom line is closed and the third control signal CTL3 is sent to the fourth switch 234 in step S213. Under the effect of the delivery of the third control signal CTL3, the fourth mobile contact point 234c of the fourth switch 234 is connected to the primary contact point 234a of this switch, which disconnects the intercom circuit part 220 by

  compared to the right speaker 270 '.

  Then, in step 214, if the user presses the hold button for the input part, a corresponding signal is sent to the controller 250 so that the latter delivers the second control signal CTL2 to the third switch 233 for placing the latter in the closed state, which cancels the standby state of the output signal of the part forming the telephone circuit 210 during step S214. Simultaneously, if the user wishes to stop the telephone conversation, steps S218,

  S219, S220 and S221 indicated above are used.

  However, in step S209 indicated previously, if the telephone call waiting button is not pressed and if the user presses the intercom communication button of the input part 50, a corresponding signal is sent to the intercom circuit portion 220 in step S215. Therefore,

  the intercom line of the inter circuit part

  phone 220 is open so that simultaneous communication via the intercom and the telephone is possible

in step S216.

  Following the step indicated above, if the utility

  reader stopped the intercom conversation there

  press the intercom communication button again

  phone. Therefore, a corresponding signal is sent to the intercom circuit portion 220 so that the intercom line is closed, and the third control signal CTL3 is sent to the fourth switch 234 in step S217. Under the effect of the output of the third control signal CTL3, the fourth mobile contact point 234c of the fourth switch 234 is connected to the primary contact point 234a of this switch, which has the effect of disconnecting the circuit forming part. intercom 220 with respect to the right speaker 270 '. Then steps S218 to S221 are executed for hanging up the telephone, if the off-hook button is pressed or if a voice hook command is issued, and cancel the deactivation. The case where the user uses the intercom and the telephone call arrives, will be described below with reference to FIG. 9. In a state, in which the user communicates with a person located at the level of the auxiliary device d intercom during step S222, if a telephone call is sent by an outside person, the call signal is sent and delivered by the telephone circuit part 210 so that the call signal detector 240 receives the call waiting and issues a

  signal corresponding to controller 250 during step S222.

  Then, in step S223, the controller 250 (a) delivers the first control signal CTL1 to the switching part 230 so that the first and second mobile contact points 231c and 232c of the first and second switches 231 and 232 are connected respectively at the secondary contact points 231b and 232b of this switch, and (b) sends the second control signal CTL2 to the third switch 233 to close the latter, which authorizes the output of the output signal by the left speaker 270 and the

  intercom communication via built-in

right speaker 270 '.

  Following step S223, if the user presses an intercom standby position button located in the input part 50, a corresponding signal is transmitted to the controller 250 during step S224. Therefore, the controller 250 transmits an intercom standby signal to the intercom circuit part 220 so that this part sends the third control signal CTL3 to the fourth switch 234, which allows the connection of the fourth mobile contact point 234c of the fourth switch 234 at the primary contact point 234a of this switch to place the

  intercom communication, during step S225.

  To answer the phone, the user presses a button to lift the input part 50 or pronounces a word or a phrase fixed in advance, for example "answering the phone". Consequently, the controller 250 receives a signal to press the off-hook button during step S226 or a signal from the input of the voice command to answer the telephone in step S227, after which the controller 250 authorizes the

  o0 communication between the caller and the user

  speaker using speakers 270 and 270 'and microphone 40, in step S228. That is, the controller 250 sends a signal to the telephone circuit part 210 to connect a call line

  telephone in this circuit part.

  To pick up the telephone, the user presses the off-hook button on the input part 50 or utters a word or a phrase fixed in advance to stop the telephone conversation, for example "hanging up the telephone". As a result, the controller 250 receives a corresponding signal from the input part 50 during step S229 or from the voice recognition part 260 during step S230, then disconnects the telephone call line in the forming part. telephone circuit 210 so the connection with the line

  call is interrupted during step S231.

  Finally, during step S232, after receiving a signal from the input part 50 or from the voice recognition part 260 for hanging up the telephone, the controller 250 sends a setting signal

  waiting for an intercom at the part forming an inter- circuit

  phone 220 so that this part delivers the third control signal CTL3 to the fourth switch 234, which has the effect of reconnecting the fourth mobile contact point 234c of the fourth switch 234 to the secondary contact point 234b of this switch, so the intercom hold is removed

in step S232.

  In step S224 indicated previously, the use

  the caller does not press the intercom standby button of the input part 50 and wishes to answer the telephone, he presses the hang up button of the input part 50 or pronounces a fixed word or phrase in advance such as "answer the phone". Consequently, the controller 250 receives a signal from the pressing of the hang-up button in step S231 or the input of the voice command to answer the telephone in step S232 so that the controller 250 sends a signal to the party forming telephone circuit 210 for making the connection of a telephone line in this part. As a result, the user transmits the telephone call through the left speaker 270 and is in communication with the person at the intercom auxiliary device through the right speaker 270 ' in step S233. To hang up the telephone, the user presses the off-hook button on the input part 50 or reads a word or phrase fixed in advance to interrupt the telephone conversation, for example “hanging up the telephone”. As a result, the controller 250 receives a corresponding signal from the input part 50 in step S234 or from the voice recognition part 260 in step S235, then disconnects the call line in the telephone circuit part 210 so that the connection with the

  telephone line is interrupted during step S236.

description.

  We will not give here the description of the

  operation of each of the elements indicated above since it is identical or similar to what has been described in the audio system 60 of the first and second embodiments. However, we will describe below

  in more detail the switching part 340.

  The switching part 340 comprises a first switch 341, a second switch 342, a third switch 343, a fourth switch 344, a fifth switch 345 and a sixth switch 346. The first switch 341 further comprises primary contact points 341a, a secondary contact point 341b and a first movable contact point 341c; the second switch 342 has a primary contact point 342a, a secondary contact point 342b and a movable contact point 342c; the third switch 343 has a primary contact point 343a, a secondary contact point 343b and a third movable contact point 343c; the fifth switch 345 includes a primary contact point 345a, a secondary contact point 345b and a fifth movable contact point 345c; and the sixth switch 346 includes a contact point 346a, a contact point

  secondary 346b and a sixth mobile contact point 346c.

* The fourth switch 344 has only two contact points so that this switch is controlled

  only in on and off states.

  If the first mobile contact point 341c of the first switch 341 is connected to the primary contact point 341a of this same switch, if the second mobile contact point 342c of the second switch 342 is connected to the contact point 342a of this switch, if the third mobile contact point 343c of the third switch 343 is connected to the second contact point 343b of this switch, if the fourth switch 344 is closed, if the fifth mobile contact point 345c of the fifth switch 345 is connected to the primary contact point 345a of this switch and if the sixth movable contact point 346c of the sixth switch 346 is connected to the primary contact point 346a of this switch, the signal output from the audio circuit part 300 is performed at

  On the other hand, if the user presses an intercom call button 70 while music is delivered by the audio circuit part 300, a third control signal CTL3 is delivered by the intercom circuit part 330 to the switching part 340. As a result, the third movable contact point 343c of the third switch 343 is connected to the primary contact point 343a of this switch so that a

  intercom call ringtone is issued by the built-in

  left speaker 380, while the signal output from the audio circuit portion 300 is achieved by the

380 'speaker.

  At this instant, if the user wishes to mute the music, he presses a mute button on the input part 50 so that a corresponding signal is sent to the controller 360. This is why a fourth control signal CTL4 is sent to the fourth switch

344 to open the latter.

  In addition, for reading a message stored in the recording part 320, the user presses a recording button so that the controller 360 delivers a first control signal CTL1 to the switching part 340. in fact, the fifth and sixth mobile contact points 345c and 346c of the fifth and sixth switches 345 and 346 are connected respectively to the secondary contact points 345b and 346b of these switches. With this switching of the fifth and sixth switches 345 and 346, the message can be delivered to the speakers 380 and 380 'from

the recording part 320.

  In the case where a person located outside sends a telephone call while reading the message as indicated above, all of the control signals CTL1, CTL2, CTL3 and CTL4 are delivered by the controller 360 so that the first point of contact mobile 341c of the first switch 341 is connected to the secondary contact point 341b of this switch, as the third mobile contact point 343c of the third switch 343 is connected to the secondary contact point 343b of this switch, as the fifth mobile contact point 345d of the fifth switch 345 is connected to the primary contact point 345a of this switch, that the second movable contact point 342c of the second switch 342 is connected to the secondary contact point 342b of this switch, that the fourth switch 344 is placed at the closed state and the sixth movable contact point 346b of the sixth switch 346 is connected to the primary contact point 346a of this switch. Therefore the user and the caller can maintain

  a telephone conversation through the built-in

  speakers 380 and 380 'of the microphone 40.

  If the intercom call button 70 is pressed while reading the message stored in the recording part 320, the controller 360 delivers the third control signal CTL3 so that the third mobile contact point 343c of the third switch 343 is connected to the primary contact point 343a of this switch, and delivers the fourth control signal CTLK so that the fourth switch 344 is placed in the open state, and sends the first control signal CTL1 so that the sixth mobile contact point 346c of the sixth switch 346 is connected to the primary contact point 346a of this switch, which

  establishes intercom communication.

  Likewise an internal speaker 390 is also included in the audio system 60 of this third embodiment. To do this, the user presses a speaker button located in the input part so that a corresponding signal is sent to the controller 360. As a result, the controller 360 delivers an output signal to the speaker internal 390 to activate an amplifier 391 of this speaker. Under the effect of the activation of the amplifier 391, words spoken in the microphone 40 by the user are amplified to a predetermined level and delivered by a speaker part 392 of the internal speaker 390.
