The MUTE circuits are mainly realized by EC；The sequential that is switched on is by CPLD (Complex Programmable Logic
Device, Complex Programmable Logic Devices) control, it presses power button and starts timing, system loads audio driven, in audio frequency control
Before chip reset, EC makes HW_MUTE_EC signals effective, so as to drive MUTE_TR signals；Also, EC is in detecting off signal
Meanwhile activate MUTE_TR signals；MUTE_TR signal activation MUTE circuits filter out generation on left and right acoustic channels transmission signal line
Abnormal sound.
The audio MUTE circuits high-pass filtering, low-pass filtering part, using formula for the π RC of F=1/2, the frequency to be filtered out
Rate range can be realized by setting resistance value and capacitance.
Preferably, the cpu chip is connect by MCS9990, USB HUB controllers with audio control chip.
Preferably, the audio output apparatus is earphone interface.

The a kind of of the present invention produces what Feiteng processor platform audio MUTE circuits had compared with prior art based on the whole nation
Advantageous effect is：Should EC (Embedded Controller, embedded controller) be passed through based on platform audio MUTE circuits of soaring
MUTE circuits are controlled, adding in the audio output apparatus of MUTE circuits can obtain filtering out the high-quality fidelity audio of noise, generate
Noise on left and right acoustic channels transmission signal line can be lowered level, can greatly improve the sound output matter of audio frequency apparatus
Amount.
Description of the drawings
Attached drawing 1 is the audio MUTE circuit block diagrams；
Attached drawing 2 is the fundamental diagram of the EC；
Attached drawing 3 is the fundamental diagram of the MUTE circuits.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, it below in conjunction with specific embodiment, and refers to
Attached drawing, to of the present invention a kind of based on whole nation production Feiteng processor platform audio MUTE circuit further descriptions.
It is of the present invention a kind of based on whole nation production Feiteng processor platform audio MUTE circuits, by being put down in Feiteng processor
MUTE circuits are increased on the mainboard of platform, and pass through EC (Embedded Controller, embedded controller) control MUTE lines
Road, to filter out the effect of noise, adding in the audio output apparatus of MUTE circuits can obtain filtering out the high-quality fidelity of noise
Audio, level can be lowered by generating the noise on left and right acoustic channels transmission signal line.
Embodiment 1：
It is a kind of based on whole nation production Feiteng processor platform audio MUTE circuits described in the present embodiment, such as 1 audio MUTE of attached drawing
Shown in circuit block diagram, mainly including cpu chip, audio control chip, audio output apparatus and MUTE circuits, the cpu chip
It is connect by MCS9990, USB HUB controllers with audio control chip, the audio control chip connects audio output apparatus
（Earphone interface）, the MUTE connections audio control chip, and MUTE circuits, while the MUTE circuits are controlled by EC
Connect audio output apparatus.In this way, the audio output apparatus by audio MUTE circuits（Earphone interface）It can be filtered out
The high-quality fidelity audio of noise, level can be lowered by generating the noise on left and right acoustic channels transmission signal line, can be significantly
Improve the sound output quality of audio output apparatus.
As shown in 1 voice band line block diagram of attached drawing, audio control chip is also connected with Mike described in the audio MUTE circuits
Interface and loud speaker, and the loud speaker connects the MUTE circuits.It is described in audio MUTE circuits described in the present embodiment
Cpu chip is connected to MCS9990 using FT1000A by PCIE buses, and the MCS9990 is that PCIE buses produce four road USB
Bus；The USB HUB controllers use USB2514, and the audio control chip uses CM6300, and peripheral earphone interface,
Microphone interface and loud speaker.
Embodiment 2：
It is a kind of described in the present embodiment that Feiteng processor platform audio MUTE circuits are produced based on the whole nation, as shown in attached drawing 2,3,
MUTE line work mechanism is mainly realized by EC；The sequential that is switched on is by CPLD (ComplexProgrammable Logic
Device, Complex Programmable Logic Devices) control, it presses power button and starts timing, system loads audio driven, in audio frequency control
Before chip reset, EC makes HW_MUTE_EC signals effective, so as to drive MUTE_TR signals.Also, EC is in detecting off signal
Meanwhile activate MUTE_TR signals.MUTE_TR signal activation MUTE circuits filter out generation on left and right acoustic channels transmission signal line
Abnormal sound.In fig. 3, the MUTE circuits high-pass filtering, low-pass filtering part are the π RC of F=1/2 using formula,
The frequency range filtered out can be realized by setting resistance value and capacitance.
It can be seen that in MUTE circuits described in the present embodiment, the transistor of MUTE circuits, drags down out on Feiteng processor platform
The abnormal pulsers that machine or shutdown moment generate, prevent noise from passing to audio output apparatus by left and right acoustic channels.Since transistor has
There is very high input impedance, larger power gain can quickly and effectively reduce the level of noise.
