The utility model content
The purpose of this utility model is to provide a kind of audio signal input pattern automatic selective system, makes audio frequency apparatus can be operated in the pattern in different audio signals source.
The audio signal input pattern automatic selective system that the utility model provides, it comprises: be used for the audio signal of input is carried out the mode identificating circuit of pattern recognition process with output digit recognition result; Be used for exporting the control circuit of corresponding control signal according to the digit recognition result of described mode identificating circuit output; Be respectively applied for the audio signal source of gathering different mode audio signal sample circuit with a plurality of different modes of the work that cooperates follow-up audio frequency apparatus; Select the audio signal sample circuit of corresponding modes to remove to drive the selection circuit of follow-up apparatus for processing audio with the audio signal of gathering corresponding modes according to the control signal of described control circuit output.
Wherein, the pattern of the audio signal of input comprises balanced mode and unbalanced mode, and corresponding mode identificating circuit comprises: audio signal is carried out the Balance Treatment circuit of Balance Treatment and the non-equilibrium treatment circuit that the audio signal of input is carried out non-equilibrium processing.
Preferably, when the audio signal of input was balanced mode, described Balance Treatment circuit was output as low level, and described non-equilibrium treatment circuit is output as high level; When the audio signal of input was non-equilibrium input, described Balance Treatment circuit was output as high level, and described non-equilibrium treatment circuit is output as low level.
Preferably, described control circuit is a kind of in single-chip microcomputer, digital signal processor, field programmable gate array and the programmable logic device.
Preferably, described selection circuit is an analog switch.
In sum, audio signal input pattern automatic selective system of the present utility model passes through the automatic identification to the pattern of the audio signal source of input, and start the corresponding audio signal of corresponding signal acquisition circuit collection to cooperate follow-up audio frequency apparatus according to the result who identifies, make it can operate as normal.
Description of drawings
Fig. 1 is an audio signal input pattern automatic selective system of the present utility model.
Embodiment
See also Fig. 1, audio signal input pattern automatic selective system of the present utility model mainly comprises: the audio signal sample circuit of mode identificating circuit, control circuit, a plurality of different modes, selection circuit, in the present embodiment, the input pattern of audio signal comprises two kinds of balanced mode and unbalanced mode, and the respective audio signal acquisition circuit comprises the audio signal sample circuit and the nonequilibrium audio signal sample circuit of balanced mode.
Described mode identificating circuit is used for the audio signal of input is carried out pattern recognition process with output digit recognition result, in the present embodiment, it comprises audio signal is carried out the Balance Treatment circuit of Balance Treatment and to the audio signal non-equilibrium treatment circuit that carries out non-equilibrium processing of input, wherein Balance Treatment circuit and non-equilibrium treatment circuit can be realized by software in DSP, promptly when the audio signal of input is balanced mode, described Balance Treatment circuit is output as low level, described non-equilibrium treatment circuit is output as high level, and promptly Shu Chu digit recognition result is 01; When the audio signal of input is non-equilibrium input, described Balance Treatment circuit is output as high level, and described non-equilibrium treatment circuit is output as low level, and promptly Shu Chu digit recognition result is 10, this identifying and principle are the technology that those skilled in the art have been familiar with, so be not described in detail in this.
The figure pattern result that described control circuit is used to discern described mode identificating circuit output is with the output corresponding control signal, and it can be single-chip microcomputer, digital signal processor, field programmable gate array (PFGA) or programmable logic device (CPLD) etc.
The audio signal sample circuit of described a plurality of different modes is respectively applied for the audio signal source of collection different mode to cooperate the work of follow-up audio frequency apparatus, be the audio signal that the audio signal sample circuit of balanced mode is used to gather balanced mode, nonequilibrium audio signal sample circuit is used to gather the audio signal of unbalanced mode.
Described selection circuit selects the audio signal sample circuit of corresponding modes to remove to drive follow-up apparatus for processing audio with the audio signal of gathering corresponding modes according to the control signal of described control circuit output, it can be analog switch etc., described analog switch is carried out on-off action according to described control signal, and then the operation of the audio signal sample circuit of the audio signal sample circuit of control balanced mode or unbalanced mode.
Be noted that, when described mode identificating circuit is exported other recognition results, for example by the Balance Treatment circuit be output as 0, when non-equilibrium treatment circuit changes to the both and is 1 when being output as 1, the control signal of control circuit output can not change because this moment can be input audio signal temporary transient pause or inserted due to the single-ended signal source.
In sum, audio signal input pattern automatic selective system of the present utility model by to the pattern recognition of the audio signal of input to open the audio collection circuit of corresponding modes, to promote follow-up apparatus for processing audio (for example sound console) energy operate as normal, make the user can be relieved to the voice data of follow-up audio frequency apparatus input arbitrary patterns, and need not to worry to cause the problem that follow-up equipment can't operate as normal (for example can't pronounce) because of the audio signal form is incompatible, no longer require the user to possess corresponding professional knowledge level, greatly reduce the use difficulty of user each audio frequency apparatus.
