The input of described 51 single-chip microcomputers is connected with the outfan of audio collection unit, and described 51 single-chip microcomputers divide It is not bi-directionally connected with SRAM recording and playback ic and encoding and decoding speech unit one, the outfan of described 51 single-chip microcomputers It is connected with the outfan of audio playing unit.

Described audio mixing talk client includes single-chip microcomputer, for the voice encoding speech data or decoding Decoding unit two, speech chip for audio information, and described speech decoding unit two and single-chip microcomputer Being bi-directionally connected, described single-chip microcomputer is bi-directionally connected with speech chip.

Speech decoding unit two in described audio mixing talk client is conversed with several respectively by communication module Encoding and decoding speech unit one in device realizes two-way signaling and connects.

Preferably, described encoding and decoding speech unit one and encoding and decoding speech unit two are encoding and decoding speech core Sheet ISD2560.

Preferably, described SRAM recording and playback ic uses WT series, and concrete employing model is WTSRB006A's Recording and playback ic.

Preferably, described speech chip use PM50 series, its be single-chip microcomputer, speech processor and The combinative structure of FLASHRAM.

Preferably, described communication module uses CDMA CDMA2000 module.

Compared with prior art, the beneficial effects of the utility model are: the packet audio mixing call that this parameter is controlled Device, by the speech decoding unit two in audio mixing talk client, communication module, several communicators The cooperation of interior encoding and decoding speech unit one, after the audio coding that can be gathered by several communicators, passes through Communication module is concentrated and is sent to audio mixing talk client, and the speech decoding unit two in audio mixing talk client is again Several audio frequency received are carried out, after decoded audio mix, then carries out Unified coding, communication Module i.e. CDMA CDMA2000 module, by audio mixing send to multiple addresses communicator in, finally by Audio playing unit in several communicators broadcasts audio mixing, so that this device has conveniently reaches multiple The audio mixing effect of communicator；Depending on the quantity of the communicator demand by professional or user so that In this device, the number parameter of communicator has controlled effect.

Additionally, the packet audio mixing communicator that this parameter is controlled, by the audio collection list to fixed sample rate The speech data that unit is gathered carries out coded treatment, and by the speech data after coding, passes through CDMA CDMA2000 module sends to client so that voice data network can bear the transmission of speech data, no Need to replace with the audio chip of audio collection terminal the audio chip of variable sample rate so that it is have and can drop The effect of low call installation cost.

Accompanying drawing explanation

Fig. 1 is this utility model system principle schematic diagram.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model The scope of protection.

Refer to Fig. 1, a kind of technical scheme of this utility model offer: the packet audio mixing call that a kind of parameter is controlled Device, including audio mixing talk client, communication module and several communicators, each communicator is equal Including 51 single-chip microcomputers, for gathering the audio collection unit of speech data with fixed sample rate, for voice Encoding and decoding speech unit one that data carry out encoding or decode, after broadcast decoder, the audio frequency of voice data is broadcast Put unit, SRAM recording and playback ic for recording playback audio-frequency information.

In this utility model, audio collection unit is the immutable audio chip of sample rate；Audio playing unit For speaker.

The input of 51 single-chip microcomputers is connected with the outfan of audio collection unit, 51 single-chip microcomputers respectively with SRAM Recording and playback ic and encoding and decoding speech unit one are bi-directionally connected, the outfan of 51 single-chip microcomputers and audio playing unit Outfan connect.

Audio mixing talk client includes single-chip microcomputer, for the tone decoding encoding speech data or decoding Unit two, speech chip for audio information, and speech decoding unit two is bi-directionally connected with single-chip microcomputer, Single-chip microcomputer is bi-directionally connected with speech chip.

Speech decoding unit in audio mixing talk client two by communication module respectively with several communicators Interior encoding and decoding speech unit one realizes two-way signaling and connects.

In this utility model, encoding and decoding speech unit one and encoding and decoding speech unit two are encoding and decoding speech Chip I SD2560, the speech data that 51 single-chip microcomputers send can be compiled by phonetic codec chip ISD2560 Code, it is possible to the voice data received is decoded.

In this utility model, SRAM recording and playback ic uses WT series, and concrete employing model is WTSRB006A's Recording and playback ic, its record length can be changed in the range of 4-8S by the frequency of regulation oscillation resistance, can only Store one section of voice, need very small area analysis to preserve voice.Compared to APR series, its playback circuitry is simple, The phonetic storage time is shorter, price is more honest and cleaner.
