Embodiment
It should be appreciated that specific embodiment described herein is not intended to limit the present invention only to explain the present invention.
The present invention provides a kind of method for switching and controlling Audio squealing during audio output, referring to Fig. 1, there is disclosed this hair
A bright embodiment, in the present embodiment, the method for Audio squealing is controlled to comprise the following steps during the switching audio output：
Step S10, detecting exports Audio conversion to the switching signal that audio is exported by earphone by wireless audio devices；
In the present embodiment, after the earphone interface of earphone insertion remote control, remote control can send out earphone interface status signal
Go out, now, can judge whether earphone inserts the earphone of remote control by the earphone interface status signal that sensing remote controller is sent
Interface, and using the remote control detected send earphone interface status signal be used as by wireless audio devices output Audio conversion to
By the switching signal of earphone output audio, the audio output carried out by wireless audio devices is switched to audio is carried out by earphone
Output.
Step S20, when detecting the switching signal, the audio signal data of acquisition is respectively stored in two storages
In area；
In the present embodiment, when detecting above-mentioned switching signal, the audio signal data of acquisition is respectively stored in first
In memory block and the second memory block, wherein, audio signal data of first memory block for storage by earphone output audio, second
Memory block is used to deposit the audio signal data for exporting audio by wireless audio devices.
Step S30, it is used for ear after the volume amplitude of the audio signal data in two memory blocks being done into amount of decrease processing respectively
The audio output of machine and the audio output of wireless audio devices.
In the present embodiment, the volume amplitude of the audio signal data in the first memory block is subjected to amount of decrease processing, and send
To the earphone interface of remote control, to export the audio signal for passing through amount of decrease processing by earphone；By the audio in the second memory block
The volume amplitude amount of decrease of signal data is sent to wireless audio devices to zero, to export the volume width by wireless audio devices
The audio signal that degree is zero；The amount of decrease that the volume amplitude of the audio signal data by the first memory block is carried out is according to ear
The power of machine correspond to the earphone of different capacity come what is carried out, by the volume amplitude of the audio signal data in the second memory block
It is different to carry out the amplitude of amount of decrease, to avoid the sound that earphone exports excessive or too small.
Due to controlling the method for Audio squealing when the present invention switches audio output by the way that the audio signal data of acquisition is divided
It is not stored in two memory blocks, and by being used for after the audio signal data in two memory blocks is adjusted into volume amplitude respectively
The audio output of earphone and the audio output of wireless audio devices, therefore the audio of earphone can be controlled defeated and wireless audio devices
Audio output in certain amplitude range, again can be with so as to can both prevent the influence of wireless audio devices output sound
Avoid wireless audio devices from occurring switch in switching process to make a whistling sound.
Referring to Fig. 2, to realize the inventive method, Audio squealing is controlled when providing a kind of switching audio output accordingly
