Description of the drawings
Attached drawing described herein is used for providing further understanding the embodiment of the present invention, constitutes one of the application
Point, do not constitute the restriction to the embodiment of the present invention；
Fig. 1 is the principle schematic of existing general headrest；
Fig. 2 is the principle schematic of the passive PTT earphones of public network intercommunication used based on regular handset.
Specific implementation mode
The present invention provides the passive PTT earphones of the public network intercommunication used based on regular handset, solve and do not have currently on the market
Have the technical issues of passive PTT earphones that can be used on common intelligent machine, realize regular handset could be used that meet PTT by
The earphone of button custom carries out intercommunication, and PTT earphones of the invention itself are not necessarily to upper battery, directly take electricity from mobile phone.
To better understand the objects, features and advantages of the present invention, below in conjunction with the accompanying drawings and specific real
Mode is applied the present invention is further described in detail.It should be noted that in the case where not conflicting mutually, the application's
Feature in embodiment and embodiment can be combined with each other.
Many details are elaborated in the following description to facilitate a thorough understanding of the present invention, still, the present invention may be used also
Implemented with being different from the other modes being described herein in range using other, therefore, protection scope of the present invention is not by under
The limitation of specific embodiment disclosed in face.
- Fig. 2 is please referred to Fig.1, it is described this application provides the passive PTT earphones of the public network intercommunication used based on regular handset
PTT earphones include：
Earphone jack wiring, electricity-fetching module, left receiver, sound pick-up, controller, PTT button；
Electricity-fetching module one end is connect with power supply VCC, and the other end of electricity-fetching module is connect with the ends R of earphone jack wiring；Ear
The ends L of machine jack are connect with one end of left receiver, one end of sound pick-up, the ends MIC of earphone jack wiring, controller it is defeated
Outlet is connect with contact A；The other end, the ends GND of earphone jack wiring, the other end of sound pick-up, the controller of left receiver
... it holds, one end of PTT button is connect with contact B；The input terminal of controller and the other end of power supply VCC and PTT button are equal
Connection.
The passive PTT earphones of the present invention need to ensure interface identical with general headrest, that is, need in general headrest principle
On be transformed.
General headrest is in use, push-to-talk button presses and releases, i.e., thus sound pick-up is obtained by of short duration short circuit, smart mobile phone
Signal starts to sample from sound pick-up；Push-to-talk button presses and releases again, and smart mobile phone, which obtains same signal, to be stopped from sound pick-up
Sampling.
To allow intelligent machine to obtain same signal, invention increases electricity-fetching module, controller and PTT button.
Concrete operations and interlock circuit sequential are：
1. when PTT is not pressed, controller OUT is in high impedance, so being equivalent to off state between A and B.At this time at IN
In high level.
2. after PTT is pressed and held, it is low level that controller, which detects that IN inputs have high level variation, is kept in OUT
50ms exports low level, i.e. access is formed between AB, triggers the drop-down pulse of an about 50ms.After drop-down pulse generates, control
Device reverts to high-impedance state in OUT so that the anti-state of open circuit is still between A and B.Although in this way, at this time PTT button be constantly in by
Lower state, but full simulation common headphones trigger push-to-talk buttons, and thus smart mobile phone can obtain identical signal and start to record
Sound.
3. after PTT releases, it is high level that controller, which detects that IN inputs are changed by low level, keeps 50ms defeated in OUT
Go out low level, is i.e. forms access between AB, triggers the drop-down pulse of an about 50ms.After drop-down pulse generates, controller is in OUT
Revert to high-impedance state so that the anti-state of open circuit is still between A and B.It is pressed in this way, full simulation common headphones again trigger call
Thus button, smart mobile phone can obtain identical signal and stop recording.
Because PTT earphones only need that monophonic, the present invention is supported to convert the audio output of right channel to control
The Vcc of device is inputted.I.e. after being inserted into earphone, earphone is really to be powered by the right channel of mobile phone.Since it is desired that right channel supplies
Electricity, i.e. right channel need the voice signal of independent play-out certain frequency.
Although preferred embodiments of the present invention have been described, it is created once a person skilled in the art knows basic
Property concept, then additional changes and modifications may be made to these embodiments.So it includes excellent that the following claims are intended to be interpreted as
It selects embodiment and falls into all change and modification of the scope of the invention.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
God and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
