Problems solved by technology

The audio noise will instantly trigger and shut down the audio equipment, causing the audio equipment to emit a "POP" sound, which may damage the audio equipment or affect the service life of the audio equipment
In addition, the "POP" sound from the audio device may mislead the user into thinking that the audio device or the notebook computer is malfunctioning, or that the sound quality of the audio device or the audio output of the notebook computer is poor, which may cause harm to the user. Unnecessarily annoying or dissatisfied users

Embodiment Construction

[0016] Figure 2A It is a schematic diagram of the basic structure of the audio equipment protection system 2 of the present invention. As shown in the figure, the audio equipment protection system 2 of the present invention is applied in an electronic equipment 1 electrically connected with an audio equipment 11, such as a notebook computer, Personal computer, TV, etc. In this embodiment, a notebook computer is taken as an example for illustration. The signal output from the electronic device includes at least an audio signal, a power on / off signal and a trigger signal, wherein the audio signal makes the audio device run , the power on / off signal turns on / off the power of the electronic device, and the potential conversion program of the trigger signal is executed when the electronic device is booting up, lagging behind the execution of the potential conversion program of the power on / off signal, and vice versa , the potential conversion program of the trigger signal is execu...

Abstract

The invention discloses an audio equipment protecting system, the audio equipment protecting system is applied in electronic equipment which is electric connected with audio equipment, the electronicequipment at least output audio signal, power on / off signal and trigger signal, the audio equipment protecting system includes: switching unit; and control unit; the audio equipment protecting systemin the invention can eliminate audio noise output by electronic equipment on / off, so damnification of audio equipment induced by instant trigger and closing of noise can be avoided, so the audio equipment can not send audio noise of 'POP', obsession and inconvenience of user by audio noise can be eliminated.

Description

technical field [0001] The present invention relates to an audio equipment protection system, in particular to an audio equipment protection system that eliminates the output audio noise when the electronic equipment is powered on / off, and avoids the audio equipment being damaged by the audio noise's instantaneous triggering and shutdown. Background technique [0002] Electronic devices (such as personal computers, notebook computers, etc.) can be connected to audio devices to play media files (such as audio files), thereby increasing the entertainment function of the electronic devices. [0003] Figure 1A It is a circuit diagram of an existing notebook computer electrically connected to an audio device. The notebook computer includes an audio signal codec unit 10, and the output audio signal (AUDIO_L / AUDIO_R) is electrically connected to an audio device 11. As shown in the figure, it is To improve the sound effect of the audio equipment, DC blocking capacitors C433 and C43...
