Compared with prior art, PTT controling appliance of the present invention has following beneficial technical effects:
PTT controller of the present invention changes toggle switch by stirring, just first switch S 1 often opens or the normally closed a kind of trivial state of deciding, and in conjunction with headset give orders or instructions, when just pressing the PTT button, conducting in the time of touch-switch S2 and S3 has realized multiple headset operation principle.PTT controller of the present invention has the simple and easy advantage of realization of circuit structure, can be used on the multiple intercom headset.
Description of drawings
Fig. 1 is the external structure schematic diagram according to PTT controller of the present invention;
Fig. 2 is the electrical block diagram of PTT controller of the present invention; And
Fig. 3-6 is respectively one of user mode schematic diagram of PTT controller shown in Figure 2, two, three and four.
Embodiment
As shown in Figure 1, the PTT controller that is used for the intercom headset that proposes of the present invention comprises: fuselage main body 1 and be fixed on fuselage main body 1 on second female seat 5 of PTT button 2, toggle switch 3, first female seat 4 that is connected with intercom and connection headset (comprise and be used to listen to the earphone of voice and the microphone M1 that is used to talk).Be in different on off states by PTT button 2, toggle switch 3 on the control fuselage main body 1, can obtain different circuit structures, thereby can on different intercom headsets, use, that is to say that PTT controller of the present invention can be selected the intercom headset circuit of multiple different structure as required.
In conjunction with shown in Figure 2, the first connector J1 is first female seat, 4, the second connector J2 shown in Figure 1 and is second female seat 5 shown in Figure 1; First switch S 1 is toggle switch shown in Figure 13; PTT button 2 comprises the 2nd S2 and the 3rd switch S 3; And first switch S 1 is serially connected between current-limiting resistance R1 and the 3rd switch S 3.
Wherein, the first connector J1 has 4 pins, is respectively: MIC-OUT pin, PTT pin, SPK-IN pin and GND pin; The second connector J2 has 3 pins, is respectively: MIC-IN pin, SPK-OUT pin and GND pin; And the SPK-IN pin of the first connector J1 is connected with the SPK-OUT pin of the second connector J2, and the GND pin of the first connector J1 is connected with the GND pin of the second connector J2, and the MIC-IN pin of the second connector J2 connects microphone M1.
Fig. 3 shows a user mode according to PTT controller of the present invention.Particularly, when first switch S 1 is pushed off-state, press PTT button 2, second switch S2 is connected, the 3rd switch S 3 disconnects, and at this moment, the MIC voice signal that microphone M1 produces is from the MIC-OUT pin output of the first connector J1.In other words, the user presses PTT button 2 and can speak by microphone M1, and by first connector J1 be transferred to the intercom that with first connector J1 be connected with voice signal this moment.When the user unclamped PTT button 2, the MIC-IN pin of the second connector J2 and microphone M1 connected, the voice signal that the other side that the user can be transmitted to the SPK-IN pin from the first connector J1 by the earphone receiving that is connected with the second connector J2 sends.
Fig. 4 shows another user mode according to PTT controller of the present invention, promptly, when first switch S 1 is pushed off-state, press PTT button 2, second switch S2 and the 3rd switch S 3 are connected simultaneously, the PTT pin of the first connector J1 is by the 3rd switch S 3 ground connection, and the voice signal of microphone M1 generation simultaneously also can be sent to the intercom that is connected with the first connector J1 by second switch S2.That is to say that the user presses PTT button 2 and can speak by microphone M1, and voice are sent.And unclamp PTT button 2, the voice signal that the other side that the user can be transmitted to the SPK-IN pin from the first connector J1 by the earphone receiving that is connected with the second connector J2 sends.
Fig. 5 and Fig. 6 show another user mode according to PTT controller of the present invention, promptly, when first switch S 1 is pushed on-state, press PTT button 2 simultaneously and second switch S2 and the 3rd switch S 3 are connected, the MIC-OUT pin of the first connector J1 is by the 3rd switch S 3 ground connection, and the voice signal that while microphone M1 sends also can be transferred to the MIC-OUT pin of the first connector J1 by second switch S2.That is to say that the user presses PTT button 2 and can speak by microphone M1, voice signal sends from the intercom that is connected with the first connector J1.And unclamping PTT button 2, the user just can hear the voice signal that the other side of transmitting from the SPK-IN pin of the first connector J1 sends by the earphone that is connected with the second connector J2.Wherein, the MIC-OUT pin that being switched on or switched off of second switch S2 is used for controlling the first connector J1 is connected with microphone M1 or disconnects, and the 3rd switch S 3 is switched on or switched off and is used for controlling MIC-OUT pin ground connection or earth-free.
Although describe the present invention with reference to disclosed here system and method, the present invention is not limited to given details, and the application is intended to cover these changes or the variation in the scope that can fall into improvement purpose or following claim.
