Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings and specific realApplying mode, the present invention is described in further detail.
Embodiment one
The exception of audio signal can be embodied by the variation of the value of register, when the value of register is unsatisfactory for default itemWhen part, it is possible to determine that electrostatic etc. causes influence to audio signal, keeps audio signal abnormal.
Referring to Fig.1, a kind of step flow chart of audio-frequency detection of the embodiment of the present invention one is shown, this method can be withApplied to regarding networked terminals, following steps are can specifically include：
Step 101, the value of the register regarding networked terminals sound intermediate frequency processing chip is obtained.
Audio signal transmission is stored in the register of audio processing chip to regarding networked terminals, obtains the registerValue.
Step 102, judge whether the value of the register meets preset condition.
Specifically, judge whether the value of register obtained meets preset condition, when detecting that the value of register is unsatisfactory forWhen preset condition, then audio signal exists abnormal, needs the value for resetting register.Such as：Detection judge register value whetherWithin a preset range, if so, determination meets preset condition, if it is not, being then unsatisfactory for preset condition.Wherein, people in the artMember can be configured above-mentioned preset condition according to actual conditions, is not particularly limited to this in the embodiment of the present invention.
Step 103, if not satisfied, then resetting the value of the register.
If judge that the value of register is unsatisfactory for preset condition, the value of register is reset, avoids the audio of subsequent transmissionSignal can not in normal storage to register, specifically can by being connected to the reset circuit of audio processing chip, to its intoRow resetting.
Audio-frequency detection provided in an embodiment of the present invention, by during audio transmission, detecting audio processing chipRegister value, judge whether the value of register meets preset condition, if not satisfied, then resetting the value of register, Ke YiyouEffect avoids electrostatic influences such as abnormal caused by audio signal, at the same time it can also prevent electrostatic from causing to damage to audio processing chipIt is bad.
Embodiment two
With reference to Fig. 2, a kind of step flow chart of audio-frequency detection of the embodiment of the present invention two is shown.
Audio-frequency detection provided in an embodiment of the present invention includes the following steps：
Step 201, the electrostatic leakage module connected by shown audio processing chip is to being transmitted to shown audio frequency process coreThe electrostatic of on piece is released.
It is obtaining before the value of the register of networked terminals sound intermediate frequency processing chip, is first passing through electrostatic leakage module to warpIt crosses the electrostatic that audio transmission line is transferred to depending on networked terminals to release, in source, has first at least obstructed partial electrostatic to audioInfluence caused by transmission, if the electrostatic leakage module can all release electrostatic, in subsequent detection, audio signalThere is no exceptions, can direct exports audio signal.If the electrostatic leakage module can not release to electrostatic completely, subsequent inspectionDuring survey, audio signal is further processed, avoids the exception of audio signal.
The specific electrostatic leakage module includes Transient Suppression Diode, the Transient Suppression Diode and audio processing chipElectrical connection, releases to the signal for reaching audio transmission line by Transient Suppression Diode.
Step 202, the value of the register regarding networked terminals sound intermediate frequency processing chip is obtained.
By electrostatic leakage module, to being transmitted to after the electrostatic depending on networked terminals releases, then obtain regarding networked terminalsThe value of the register of sound intermediate frequency processing chip.
Step 203, the value of the register of acquisition is compared with preset range.
After the value for obtaining register, the value of the register is compared with preset range.
Step 204, when the value of the register is not in values, it is determined that be unsatisfactory for preset condition.
When the value of the register of acquisition is not in the preset range of setting, then it can determine that the value of register is unsatisfactory forPreset condition.Wherein, those skilled in the art can be configured above-mentioned preset range according to actual conditions, and the present invention is implementedThis is not particularly limited in example.
Step 205, if not satisfied, then resetting the value of the register.
If judge that the value of register is unsatisfactory for preset condition, the value of register is reset, avoids the audio of subsequent transmissionSignal can not in normal storage to register, specifically can by being connected to the reset circuit of audio processing chip, to its intoRow resetting.After the completion of resetting, continue the value for obtaining register.
If the value of register meets preset condition, continue the value for obtaining register, without carrying out other operations.
Audio-frequency detection provided in an embodiment of the present invention, by during audio transmission, detecting audio processing chipRegister value, judge whether the value of register meets preset condition, if not satisfied, then resetting the value of register, Ke YiyouEffect avoids electrostatic influences such as abnormal caused by audio signal, at the same time it can also prevent electrostatic from causing to damage to audio processing chipIt is bad.
