Abstract
The utility model relates to an additional background sound device of a call, which is connected with a telephone accessing to a public telephone network. The additional background sound device of the call comprises an off-hook detection module, a background sound control module, an audio modulation module and the linear coupler, wherein the off-hook detection module is used for detecting whether the telephone is in an off-hook state; the background sound control module is used for judging to start the call background sound instructions when the telephone is off-hook; the audio modulation module is used for modulating the background sound into an audio signal; and an input end of the linear coupler is connected with the audio modulation module, and an output end thereof is connected with the public telephone network. The additional background sound device of the call can realize that the telephone is connected with general purpose computer equipment, thus realizing the function of additional background sound in a call.
Description
(1) technical field
The utility model relates to a kind of conversation additional background mixer.
(2) background technology
Provide conversation additional background sound function on existing some medium-to-high grade telephone set/mobile phone, promptly when conversation, started the background sound program and realized call background voice.But existing call background voice is solidificated on the telephone set usually, can't be connected with general purpose computing device.
(3) utility model content
The utility model mainly is to solve the above-mentioned technical problem of mentioning, and a kind of conversation additional background mixer is provided.
Described conversation additional background mixer is connected with the telephone set that inserts public telephone network, and described conversation additional background mixer comprises:
One is used to detect the whether off-hook detection module of off-hook of telephone set;
One is used for judging when the telephone set off-hook, starts the background sound control module of call background voice instruction;
