Abstract

PURPOSE:To start reproduction at and after the head of a message with plural circuits for each circuit by converting the message of a sound source into digital codes to store them temporarily to a memory and then reproducing the message after performing the program searching with those circuits independently of each other. CONSTITUTION:A sound message part including a start tone which is reproduced repetitively is digitized out of a sound source 1 by a sound coding circuit 3, and the start tone part is detected by a start tone detecting circuit 4. A control circuit 6 transfers the digital sound data to an address in a memory which is indicated by the 1st program counter PC within a coding cycle. Then the counter PC is counted up by one and then cleared if a signal output is delivered from the circuit 4. Then the coded sound data are read successively out of the address indicated by the value of the 2nd PC corresponding to each circuit and then transferred to sound decoding circuits 8A, 8B- to count up the 2nd PC just by one. These transferred sound data are decoded and delivered.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a paging device, and particularly to a paging device that is capable of reproducing and outputting a voice message played from one sound source to a plurality of lines from the beginning for each line. The present invention relates to a paging device.

[Background of the invention]

Conventional devices of this type include endless tape recorders,
Alternatively, it consisted only of a sound source device such as a tape recorder configured to always start playback from the beginning.

For this reason, in the former case, there is a problem in that the voice message is played randomly from the middle for each listener, resulting in poor service quality.In addition, in the latter case, the number of sound sources provided is However, it is not possible to send voice messages at the same time, and when outputting to multiple lines, it is necessary to prepare multiple sound sources, making the device expensive and requiring maintenance. .

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to solve the problems mentioned above in conventional paging devices, and to transmit audio messages played from one sound source to multiple lines. Therefore, it is an object of the present invention to provide a paging device capable of reproducing and outputting data from the beginning of each line.

[Summary of the invention]

The gist of the invention is to digitally encode messages from one sound source to reproduce voice messages - storage in memory and over multiple lines)! The point is that the playback is performed by locating the beginning of the first part.

It is composed of... As the start sound detection circuit 4, for example, one configured to detect a tone of a specific frequency can be used.

The control circuit 6 includes, for example, a micro sequencer, a coding cycle (clock) generation circuit, two program counters, etc., a memory 5, an audio encoding circuit 3, audio decoding circuits 8A, 8B, . . .・It has a function to independently control the transfer of audio data between all lines for each encoding cycle.

] The first of the two program counters is reset by the start signal of the voice message, as will be described later, and is counted up when the transfer of voice data from the voice encoding circuit 3 to the memory 5 is completed. It is.

Note that the incoming call detection circuits 9A, 9B, . Incoming call detection circuit 9Δ, 9R
When the audio data is transferred from the memory 5 to the audio encoding circuit 7, the audio data is uploaded from the memory 5 to the audio encoding circuit 7.

The operation of this embodiment configured as described above will be explained below.

A voice message including a starting sound repeatedly reproduced from a sound source 1 is transmitted via a line 2 AL, and the voice message portion is converted into digital voice by a voice encoding circuit 3 at each encoding cycle. Further, the start sound part is detected by the start sound detection circuit 4.

The control circuit 6 has one encoding period (for example, 125μ5ec)
It operates as follows. That is, the digital audio data from the audio encoding circuit 3 is transferred to the address in the memory 5 indicated by the value of the first program counter, and the first program counter is incremented by one. Here, if there is a signal output from the start sound detection circuit 4, processing is performed to clear the first program counter and write information indicating the end to the last address.

Next, for each line, the encoded audio data is sequentially read out from the address indicated by the value of the second program counter in the memory 5 corresponding to each line, and The data is transferred to the audio decoding circuits 8Δ, 8B, . . . and the second program counter is incremented by one. The audio data transferred to the audio decoding circuits 8A, 8B, . . . is decoded and output as audio.

Here, if an incoming call from the voice message listener is detected by the incoming call detection circuits 9A, 9B,..., then the process of clearing the second program counter in Section 2 is performed. conduct.

By repeating the above operations, on the one hand, the voice message output from the sound source 1 is written into the memory 5, and on the other hand, it is output from the beginning for each line that arrives at the German 5"1." That will happen.

Furthermore, even when changing the content of a message, the above operation ensures that the message that started playing before the change is output correctly until the end as it was before the change, and the message that started playing after the start of the change 1.1: After the change. Messages can be processed so that they are output as . 2. In the above embodiment, as the sound source 1, the endless
Although an example using a tape recorder has been shown, the five sound sources are not limited to this. f911 For example, one tape has been recorded with a voice message with the starting sound and ending sound of
The start sound shoulder detection circuit 4 detects the end sound as well as the start sound, and the data transfer from the voice encoding circuit 3 to the memory 5 is performed once between the start sound and the end sound. You can also limit it to just that. In this case, the present invention can be implemented in the manner described in claim (2).

Further, in the above embodiment, an example was shown in which the control circuit 6 was constructed from a micro sequencer, a coding cycle generation circuit 2, a program counter, etc., but it goes without saying that these may be replaced by other means having equivalent functions. That's a good thing.

〔Effect of the invention〕

As described above, according to the present invention, in a paging device that outputs a voice message recorded in advance on a sound source in response to incoming calls from a plurality of information listeners, a signal indicating the start time of the voice message is added to the voice message. In addition to containing
