Switching control is performed.

The battery 130 is a secondary battery that supplies electric power for operation to each part of the loudspeaker 100.

Next, the operation of the loudspeaker system having the above configuration will be described. When performing a loudspeaking operation on the loudspeaker 100 from a remote location, the mobile telephone MS, the telephone TEL, or the PHS terminal P1 is used. In the explanation below,
A case will be described as an example where the PHS terminal P1 is used to perform a loudspeaking operation on the loudspeaker 100.
The same applies when the telephone TEL is used.

First, a person who performs a loudspeaker operation (hereinafter abbreviated as operator) makes a call from the PHS terminal P1 to the PHS terminal P2. When the PHS terminal P2 receives an incoming call,
Earphone microphone plug E to earphone microphone jack EJ
Since P is connected, it automatically responds to the incoming call.

As a result, the PHS terminal P1 and the PHS terminal P
A communication link is established between the two via the base station CS1, the public network NW2, and the base station CS2, and a call becomes possible.

Thereafter, the operator operates the key operation unit of the PHS terminal P1 to send a DTMF tone signal to the PHS terminal P2, or input a voice through the microphone of the PHS terminal P1 as necessary. .

On the other hand, in the loudspeaker 100, the control unit 120 controls the loudspeaker according to the flowchart shown in FIG. First, in step 2a, the control unit 120 waits for the tone detection circuit 109 to detect a DTMF tone. Here, when the operator operates the key operation unit of the PHS terminal P1 to send out a DTMF tone signal, the tone detection circuit 109 detects and analyzes it, converts it into tone data, and outputs it to the control unit 120. As a result, the process proceeds to step 2b.

In step 2b, the control unit 120 acquires the tone data from the tone detection circuit 109, and in step 2
Move to c. The tone data acquired here is
It is treated as PIN code data. Therefore, the operator of the PHS terminal P1 needs to operate the key input unit to input the personal identification number in step 2b.

At step 2c, the control unit 120 determines whether the tone data obtained at step 2b matches the personal identification number data stored in the personal identification data area of the memory 103.

Here, the tone data is stored in the memory 10.
If it coincides with the personal identification number data stored in 3, the process proceeds to step 2d, while if it does not coincide, the process proceeds to step 2e.

At step 2e, the control unit 120 controls the tone reproduction circuit 110 to reproduce the tone sound indicating the error. This tone sound is output to the PHS terminal P2 through the earphone microphone plug EP and transmitted to the PHS terminal P1 through the communication link. As a result, the operator of the PHS terminal P1 is informed that the entered personal identification number is incorrect, and knows that he / she is not in a state capable of performing the loud voice operation.

In step 2d, the control unit 120 acquires the tone data from the tone detection circuit 109, and in step 2
shift to f. The tone data acquired here is
It is treated as data that specifies the sound mode.

Therefore, the operator of the PHS terminal P1 is
To specify "direct broadcast mode", press "#" in the key input section, while to specify "standard message mode", press "*".

In step 2f, the control unit 120 determines that the tone data acquired in step 2d is "direct broadcast mode".
It is determined whether the tone data is "#" that specifies "" or the tone data is "*" that specifies "standard message mode". Here, the tone data is
In the case of "#", the process moves to step 2g, while "*"
In the case of, the process proceeds to step 2n.

In step 2g, the control unit 120 causes the switch 1
04 is switched and controlled, the delay memory 102 and the D / A converter 105 are connected, and the process proceeds to step 2h. In this way, the operator who has specified the "direct broadcast mode" is
Voice is input through the microphone of the S terminal P1. The voice of the operator is received by the PHS terminal P2 through the communication link and input to the A / D converter 101 through the earphone microphone plug EP.

The voice of the operator is the A / D converter 1
The data is converted into audio data at 01, temporarily buffered at the delay memory 102, and delayed for output. The audio data delayed and output in this manner is output to the D / A converter 105 through the switch 104, converted into an analog audio signal here, amplified by the amplifier 106, and output from the speaker 107 in a loud voice. It Such an operator's voice loudness operation is continued until the operator performs a call end operation, or performs a voice loudness stop instruction and inputs a personal identification number.

At step 2h, the control unit 120 determines whether the tone detection circuit 109 detects a busy tone, that is, whether the communication link with the PHS terminal P1 is disconnected.

If the tone detection circuit 109 detects a busy tone, the process proceeds to step 2t. On the other hand, if the busy tone is not detected, the process proceeds to step 2i.

Therefore, when the operator of the PHS terminal P1 wants to end the loud voice, the communication link is disconnected and the busy tone is detected by the tone detection circuit 109 when the PHS terminal P1 finishes talking by an off-hook operation. Then, the process proceeds to step 2t.

In step 2i, the control unit 120 determines whether or not the tone detection circuit 109 has detected a tone from the speaker 107 that specifies the suspension of the loud sound. Here, if the tone detection circuit 109 detects a stop-designated tone,
On the other hand, the process proceeds to step 2j. On the other hand, if the stop designating tone is not detected, the process proceeds to step 2h.

Therefore, when the operator of the PHS terminal P1 wants to temporarily stop the loud sound, the PHS terminal P1
At 1, the key input section may be operated to send a specific stop designation tone.

At step 2j, the control unit 120 acquires the tone data from the tone detection circuit 109, and at step 2j
Move to k. The tone data acquired here is
It is treated as PIN code data. Therefore, the operator of the PHS terminal P1 needs to operate the key input unit to input the personal identification number in step 2j.

At step 2k, the control unit 120 determines whether or not the tone data obtained at step 2j matches the personal identification number data stored in the personal identification data area of the memory 103.

Here, the tone data is stored in the memory 10.
If it coincides with the personal identification number data stored in 3, the process proceeds to step 2l, while if it does not coincide, the process proceeds to step 2m.

In step 2l, the control unit 120 causes the switch 1
04 is switch-controlled to disconnect the delay memory 102 and the D / A converter 105, and the process proceeds to step 2h. As a result, the voice data buffered in the delay memory 102 is not output to the D / A converter 105, so that the speaker 107 is in a state of producing no sound, and the loud sound is temporarily stopped.

In step 2m, the control unit 120 controls the tone reproduction circuit 110 to reproduce the tone sound indicating an error, and then proceeds to step 2h. This tone sound is output to the PHS terminal P2 through the earphone microphone plug EP and transmitted to the PHS terminal P1 through the communication link. As a result, the operator of the PHS terminal P1 is informed that the entered personal identification number is incorrect and knows that the loudspeaking cannot be temporarily stopped.

On the other hand, in step 2n, the control section 120 acquires the tone data from the tone detection circuit 109, and shifts to step 2o. The tone data acquired here is treated as data of the identification number of the fixed message.

For this reason, the operator of the PHS terminal P1 must operate the key input unit to input the identification number of the fixed message in step 2n. To end the designation of the standard message, press "#" in the key input section.

In step 2o, the control section 120 determines whether or not the tone data acquired in step 2n is tone data "#" indicating the end of the designation of the fixed message. Here, if the tone data is "#", the process proceeds to step 2q, while if it is the identification number of the fixed message, the process proceeds to step 2p.

At step 2p, the control unit 120 records the identification number of the fixed message accepted at step 2n in the reproduction message area of the memory 103, and at step 2n
Move to.

After that, by repeating the control of steps 2n, 2o and 2p as many times as necessary, the identification numbers of a plurality of standard messages are recorded in the reproduction message area of the memory 103.

On the other hand, in step 2q, the control section 120 controls the switching of the switching device 104, connects the memory 103 and the D / A converter 105, and proceeds to step 2r.

In step 2r, the control unit 120 determines that the memory 1
The data of the voice message corresponding to the identification number recorded in the reproduction message area 03 is sequentially read from the message area of the memory 103, output to the D / A converter 105 through the switch 104, and the process proceeds to step 2s.

As a result, the read voice message data is converted into an analog voice signal by the D / A converter 105, then amplified by the amplifier 106, and the speaker 1
A loud voice is output from 07.

In step 2s, the control unit 120 determines that the memory 1
It is determined whether or not the reading of the data of the voice message corresponding to the identification number recorded in the reproduction message area 03 is completed.

If the reading of the voice message data corresponding to the identification number is completed, step 2
On the other hand, if it has not been completed yet, the process proceeds to step 2s and waits.

At step 2t, the control unit 120 causes the switch 1
04 is switched and controlled, and the input terminal of the D / A converter 105 is
The processing is terminated by setting the connection with neither the delay memory 102 nor the memory 103.

As described above, in the loudspeaker system having the above-described configuration, the person who makes a statement such as an announcement sends a voice toward the PHS terminal P2 through the PHS terminal P1 and the loudspeaker 10
At 0, the voice received by the PHS terminal P2 is output in a loud voice.

In addition, a plurality of voice messages are stored in advance in the loudspeaker 100, and the operator can select the PHS terminal P
A tone signal is sent to the PHS terminal P2 through 1 to specify a voice message to be voiced, and the voice booster 100 outputs the voice message thus designated. Therefore, according to the loudspeaker having the above-mentioned configuration, it is possible to designate a preset voice message from a remote place by using a public network or a mobile communication network and make a loud voice.

Further, since the input of the personal identification number is required to perform the voice control via the PHS terminal P1, it is possible to prevent mischief and abuse.

The loudspeaker 100 is provided with the microphone 108, and the ambient sound collected by the microphone 108 is transmitted to the PHS terminal P1 through the PHS terminal P2. Therefore, the operator of the PHS terminal P1 Loudspeaker 100

Further, the loudspeaker 100 is equipped with an A / D converter 101 and a delay memory 102 to temporarily store the voice sent from the PHS terminal P1 and then to the D / A.
The converter 105 converts the signal into an analog voice signal and outputs it in a loud voice. When a busy tone is detected from the transmitted voice, the control unit 120 controls the switch 104 to immediately stop the voice output. ing.

Therefore, even if the operator of the PHS terminal P1 disconnects the communication link by going off-hook to end the loudspeaking, or if the communication link is suddenly cut off due to the deterioration of the radio environment, the busy tone is loudly output. It can be prevented from doing.

Further, since the PHS terminal P2 obtains a voice signal to be amplified and the battery 130 is used as a power source, the loudspeaker 100 can be placed at any position within the communication area with the PHS base station. It can be installed and is suitable even when it is temporarily needed for various events, and can be installed in a vehicle such as an automobile.
