Description
Technical field
The present invention relates to audio frequency control field, more particularly to a kind of wechat sound control platform.
Background technology
Wechat (WeChat) is that one that Tencent released on January 21st, 2011 provides instant messaging for intelligent terminal
The free application program of service, Guangzhou research and development centre of the Tengxun product group train led by Zhang little Long.Wechat is supported across logical
Letter operator, spanning operation system platform quickly sent by network free (a small amount of network traffics need to be consumed) voice SMS, video,
Picture and word, it is also possible to use " shaking one by the data and location-based social plug-in unit for sharing streaming medium content
Shake ", " drift bottle ", " circle of friends ", " public platform ", the service plug such as " voice memo sheet ".
By the end of the second quarter in 2016, wechat covered China more than 94% smart mobile phone, the moon any active ues reach
To 8.06 hundred million, user covers more than 200 countries, more than 20 kinds language.In addition, wechat public's account sum of various brands has surpassed
8,000,000 are crossed, Mobile solution docks quantity more than 85000, and advertising income increases to 36.79 hundred million RMB, and wechat pays user
Then reach 400,000,000 or so.
However, the frequent life using also to people of wechat brings certain interference, such as time at dead of night, or
Other lengths of one's sleep in the non-late into the night, wechat contact person and the current state for not knowing about local device holder, still send various
Sound is reminded in message, triggering, ceaselessly to carrying out continuing interference in dormant user, has had a strong impact on stopping for user
Breath, if local device is arranged into Jing Yin in a sleep state, it is likely that can cause and extraneous lost contact, some important phones
It can not be received.
The content of the invention
In order to solve the above problems, the invention provides a kind of wechat sound control platform, transforms wechat in the prior art
The sound control pattern for the equipment installed, by the detection to current slot and to the dormant detection of user, touch
Send out and the sound of the single program of wechat is intercepted, so as in the case where that whole equipment need not be arranged into Jing Yin, you can avoid
The interference of wechat message is received in a sleep state, has ensured the normal rest of user.
According to an aspect of the present invention, there is provided a kind of wechat sound control platform, the platform include timing device, SD
