Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an audio notification device, and more particularly to an audio notification device in which the output level of audio can be freely controlled.

[Background of the invention]

Conventionally, audio notification devices that are connected to a telephone line and output information audibly using a telephone are: - The voice output level cannot be changed based on a request from the receiving side of the service, so if the recorded voice level is low or due to transmission loss on the telephone line, etc. If the output level decreases, it will not be possible to correct the decreased output level, and the necessary information will be lost. 9! The problem was that it was difficult to obtain. In addition, related devices of this type include 1, for example, #kaisho 53-29702, #kaisho 55-! 13
4!11 Publication and KvftJ Publication No. 58-115995, but both of them suggest that when the level of the recorded voice is low or there is transmission loss on the telephone line, the output level of the voice on the telephone As mentioned above, this problem was dealt with by adjusting the audio output level again and removing the audio output level.

[Purpose of the invention]

The present invention has been made in view of the problems in the prior art described above, and it is an object of the present invention to provide a voice announcement device that can correct the output level of voice in response to a request from a recipient of a voice announcement service.

[Summary of the invention]

A feature of the present invention is that it solves the problem of poor hearing by providing an audio level control section that can freely change and correct the audio output level during the audio output process.

[Embodiments of the invention]

An embodiment of the present invention will now be described in detail with reference to FIGS. 1 and 2. FIG. 1 is a specific configuration diagram of the entire voice notification device, and FIG. 2 is a diagram showing the configuration of the main parts shown in FIG. 1.

As shown in FIG. 1, there is a processing section 1 that controls the f-voice announcement device, an audio storage section 2 that stores audio, and a processing section 1 that edits and reads out the audio stored in the storage section at the request of the processing section 1. an editing control section 6 for controlling the - audio output section 4 for adapting the audio output from the utility biasing section 3 to the convenience standards of the telephone line; A trunk section 5 that simultaneously inputs and outputs the emitted information ff1 (multi-frequency signal) and the voice output to the telephone line, and a voice level control section that controls the processing section 1 (therefore, performs variable control of the voice output level) 6 and receive information from the receiving side,
It is composed of a processing section 1 and a response human power section 7 that sends data to an audio level control section 6.

The 2-audio output unit 4 is configured to increase the audio signal outputted from the audio level control unit 6 to an appropriate level @as, and an a-bus filter 9. It consists of

In addition, as shown in the circuit block diagram of FIG. 2, the audio level control s6 includes a decoder 14 that decodes the input multi-frequency signal, and the logical product of the output signal 21 of the decoder 14 and the clock pulse signal 19. An up/down counter 15 operates according to a signal obtained through the A N D circuit 24, and a digital/analog (D/A) converter 16 that converts the output signal of the up/down counter from a digital signal to an analog signal. , a 7-lip 70 switch 13 that controls the operation of the decoder 140, and a d/r protection circuit 17 that prevents decoding from stopping due to g analysis in the output signal of the decoder 14. The operation according to the embodiment will be explained. First, when an incoming call from the receiving side of the voice notification service is confirmed, a data set pulse signal is sent from the processing unit 1, the decoder of the voice level biasing unit 6 is enabled for input, and the up/down counter is activated to output the voice. The level is set to a predetermined initial state where the level is the average level.

Now, the processing unit 1 sends an audio output request to edit ft1J as
5, the 1 editing control section 3 reads the audio signal designated by the processing section 1 from the audio storage section 2, edits it into a -C sentence, and sends it to the -C audio output section 4. Therefore, in the audio output unit 4, the audio signal sent from the editing control unit 5 is amplified and reduced by the amplifier B whose amplification factor changes depending on the audio level control signal, and then the low-pass filter 917 (') removes unnecessary frequencies. The trunk section 5 sends out one voice word sent from the audio output section to the frame 4.
Send it to Makoto 12, who will make a fortune.

Here, if the audio level reproduced by the speaker is low and the receiver has difficulty hearing, the receiver inputs a predetermined length-vis code of the multifrequency signal to start adjusting the audio level. Second, the audio notification device recognizes the start of audio level adjustment and continues to output audio for a certain period of time. In this state, while the receiving side is inputting the audio level up code of the predetermined multi-frequency signal, the audio level up signal 2 is sent from the decoder 14 of the audio level control section 6.
1 is sent out, and this signal 21 and the clock pulse signal 19
The logical product of A) is taken by the JD circuit and input to the up/down counter 15, where it is counted up and converted into a digital signal.

Through the analog converter, it is input to the amplifier 8 as an audio leveler control signal 11, and the audio output level continues to rise. If the receiving side stops inputting the audio level up code, it is an up-down color.

The output of the filter 15 is fixed, and the audio output level at this time is maintained. At the same time, the input to the decoder 14 is disabled, especially when the 71J block is reset. Here, the momentary interruption protection circuit 17 is.

K is used to distinguish momentary interruptions due to the input method on the receiving side, noise on the telephone line, etc. from the stoppage of the audio level up signal.

Next, if the audio level played by the telephone is too high, input the service code to start adjusting the receiving side audio level, and then input the audio level down code. 14 outputs an audio level down signal 22, this signal 22 and the clock pulse signal 19 are ANDed by an AND circuit 251C, and the output is input to an up/down counter 15 and counted down by the up/down counter 15 to output audio. The level will go down.

Other operations are the same as when the output audio level is too low.

According to this embodiment, the audio level can be changed continuously according to a request from the receiving side receiving the voice notification service, so the receiving side can freely select the audio level whenever the service code can be input. There is an effect that it can be done.

〔Effect of the invention〕

As is clear from the above-described embodiments, according to the present invention, the audio output level is continuously changed in response to a request from the receiving side receiving the audio notification service, and the audio output level on the telephone is optimized. Since it can be used as a value, it is possible to prevent difficulty in listening due to differences in the hearing ability of the person receiving the voice notification service, environmental conditions, and even transmission loss of the telephone line, which is greatly useful for improving the service.
