Abstract

PURPOSE:To select a holding state matched with the psychological state of an opposite party who is waiting by driving a holding sound source circuit when a prescribed signal from a telephone circuit is detected in the holding state and sending holding sound different from sent holding sound or stopping the operation of the holding sound source circuit. CONSTITUTION:A transmitter 4 or a sound synthesis circuit 5 is selectively connected to a hybrid transformer circuit 1 by a holding changeover switch 3. The sound synthesis circuit 5 stores a prescribed message and first and second holding merodies and they are individually made access. A control circuit 8 monitors the output signal of a tone signal detection circuit 6 and the operation of a holding key. When the opposite party operates a * key and a tone signal corresponding to the key is sent, the tone signal detection circuit 6 outputs the detection signal to the control circuit 8. Whenever the * key is operated, a state cyclically is changed in the order of the first holding melody second holding melody mute.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone having a holding function.

[0002]

2. Description of the Related Art In recent years, for example, as disclosed in Japanese Patent Publication No. 1-53951, there is a device which sends a predetermined holding sound to the other party in the holding state.

[0003]

By the way, when the holding tone is transmitted in the holding state as described above, the other party who is kept waiting is forced to hear the holding tone without any choice. This is not preferable in the case where the other party does not personally like the held music or wants to think quietly and prepare for a conversation with the other party.

[0004]

A telephone of the present invention monitors a predetermined signal from a telephone line in a hold state and, when detecting the signal, controls a hold sound source circuit to output a hold sound. The control means for outputting a holding sound different from the above or stopping the operation of the holding sound source circuit is provided.

[0005]

Since the present invention is configured as described above, the other party waiting in the hold state can change or hold the hold tone by operating a ten key or the like to send a predetermined signal. The sound transmission can be stopped.

Embodiments of the present invention will be described with reference to the drawings.
Reference numeral (1) is a hybrid transformer circuit connected to a telephone line (L), which includes a receiver (2) and a hold switch (3).
To the telephone line (L). A transmitter (4) and a voice synthesizing circuit (5) are connected to the hold changeover switch (3), and the transmitter (4) or the voice synthesizing circuit (5) is connected by the hold changeover switch (3). Are selectively connected to the hybrid transformer circuit (1). The voice synthesizing circuit (5) is configured to store a predetermined message and the first and second hold melodies, and to be individually accessible for each. (6) is a tone signal detection circuit for detecting a tone signal from the telephone line (L), and (7) is a key circuit, which includes a ten-key pad and a hold key. (8) is a control circuit composed of a microprocessor, which controls the hold switch (3) and the voice synthesizing circuit (5) based on the tone signal detecting circuit (6) and the key circuit (7). ..

FIG. 2 shows a flow chart of the program of the main part in the hold state written in the control circuit (8), and the operation will be described based on this.

When the hold key is operated in the talking state, the control circuit (8) switches the hold changeover switch (3) from the transmitter (4) to the voice synthesizing circuit (5) side, and then the voice synthesizing circuit ( 5) is driven to send a predetermined message to the telephone line (L) via the hybrid transformer circuit (1) (steps S-1 to 3). This message is, for example, as follows.

"We are calling you right now. Please listen to the music during that time. If there is any inconvenience to the music, please press the" * "button and select your favorite state." When the output is completed and the end signal is returned from the voice synthesizing circuit (5) to the control circuit (8), the control circuit (8) drives the voice synthesizing circuit (5) so as to send the first hold melody ( Step S-4). As a result, the first hold melody is played to the other party. Thereafter, the control circuit (8) sets the counter N to 0 and monitors the output signal of the tone signal detection circuit (6) and the operation of the hold key (steps 5, 6, 13). here,
When the other party operates the "*" key and a tone signal corresponding to the key is sent, the tone signal detection circuit (6) outputs a detection signal to the control circuit (8). Control circuit (8)
Receives the detection signal, the contents of the counter N are checked (steps S-7 and 10). Here, since it is 0,
The voice synthesizing circuit (5) is driven so that the second hold melody is transmitted, and the counter N is set to 1 (steps S-8 and 9). When a detection signal is similarly input while the content of the counter N is 1, the control circuit (8) controls the voice synthesizing circuit (5) so as to stop the output of the hold melody, and brings about a so-called muting state. The counter N is set to 2 (steps S-11 and 12). Also, the counter N
If the detection signal is similarly input in the state of the content of 2, the control circuit (8) returns to step S-4 described above, and drives the voice synthesis circuit (5) so that the first holding melody is transmitted. become. That is, each time the "*" key is operated,
The state changes cyclically in the order of the first hold melody → the second hold melody → mute.

When the hold key is operated again, the control circuit (8) controls the voice synthesizing circuit (5) so as to stop the output of the hold melody, and the hold changeover switch (3) is turned on to the transmitter (4). ), And the call state is resumed (steps S-14 and 15).

[0011]

Since the present invention is configured as described above, it is possible to change the holding tone or stop the sending of the holding tone by operating the ten key or the like of the other party waiting in the holding state. , It is possible to provide a telephone that can select a hold state that matches the psychological state of the other party.
