Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement Example, is described in further detail to this utility model.It should be appreciated that specific embodiment described herein is only to explain This utility model, is not used to limit this utility model.

Fig. 1 is referred to, in one embodiment, a kind of sound card 100 includes：Audio Input Modules 10, audio frequency special effect processing core Piece 20, dio Output Modules 30, the first control 40 and the second control 41.

Audio Input Modules 10 include audio input interface, and audio input interface can pass through microphone cord with external speaker Microphone interface is connected, and audio input interface can be 3.5mm audio interface, or card agriculture interface.Audio Input Modules 10 Also include analog/digital conversion module, to convert analog signals into digital signal.

Audio frequency special effect processing chip 20 is arranged between Audio Input Modules 10 and dio Output Modules 30, to described The audio signal of Audio Input Modules input carries out special effect processing, so that the microphone signal of input is by audio frequency special effect processing The audio signal being input into after the process of chip 20 is the superposition of microphone signal and specially good effect.

Dio Output Modules 30 include audio output interface, to the audio frequency letter for processing audio frequency special effect processing chip 20 Number export to outer audio equipment.Outer audio equipment can be audio amplifier, earphone etc..Output interface can be 3.5mm interfaces, also It can be USB interface.

First control 40 and the second control 41 are electrically connected with audio frequency special effect processing chip 20, can be controlled at audio frequency specially good effect The on or off of the special effect processing function of reason chip 20, wherein, the second control 41 can also be to the control signal of the first control 40 Inverted.Specifically, the on or off of special effect processing function can be realized by triggering the first control 40, by triggering second Control 41 can equally realize the on or off of special effect processing function, when the first control 40 opens special effect processing function, second The triggering of control 41 can be inverted to the control signal of the first control 40, even if special effect processing function is switched to by open mode Closed mode.

In above-mentioned sound card, the first control 40 and the second control for beating opening/closing audio frequency special effect processing function is provided with 41, using the first control 40 and the second control 41 special effect processing function can be carried out respectively to open/closing control, while utilizing Second control 41 can be controlled the reversion of signal to the first control 40, and control mode is more flexible.

First control 40 and the second control 41 can be press button, mechanical key, knob or push rod one of which or Combination.In one embodiment, the first control 40 and the second control 41 are all mechanical key, and preferably the first control 40 is once effective Keep down state that the button for just returning to the state of upspringing effectively is pressed in next time after pressing, the second control 41 is once effectively to press The button of the state of upspringing is automatically restored to after lower.So when the first control 40 is down state, sound card long-time can be realized Special effect processing is opened, and passes through the control signal that can invert the first control 40 of pressing of the second control 41, realize sound card short Time closes special effect processing；Conversely, when the first control 40 is to upspring state, the special effect processing of sound card is closed, and leads to Cross the second control 41 and be capable of achieving short time unlatching specially good effect.By sound card as above, facilitate user according to the use feelings of oneself Condition carries out most suitable control to sound card.

In another embodiment, all to press button, preferably the first control 40 is one for the first control 40 and the second control 41 Secondary effectively to press the button for maintaining control signal after release automatically, the second control 41 could maintain to control to keep effective down state The button of signal processed.Equally can realize such as the control mode of above-mentioned mechanical key combination.
