Embodiment Construction

[0015] like figure 1 As shown, the PTT controller for the walkie-talkie headset proposed by the present invention includes: a fuselage body 1 and a PTT button 2 fixed on the fuselage body 1, a toggle switch 3, a first female seat 4 connected to the walkie-talkie, and a connection The second female seat 5 of the earphone (including the earphone for listening to the voice and the microphone M1 for speaking). By controlling the PTT button 2 and the toggle switch 3 on the fuselage body 1 to be in different switching states, different circuit structures can be obtained, so that they can be used on different walkie-talkie headsets, that is to say, the PTT controller of the present invention can Choose a variety of walkie-talkie headset circuits with different structures according to your needs.

[0016] combine figure 2 As shown, the first connector J1 is the figure 1 The first socket 4 shown, the second connector J2 is figure 1 The second female seat 5 shown; the first switch ...

Abstract

A PTT controller used in an intercom headset comprises a controller body (1), a PTT key (2) fixed on the controller body (1), a first switch (S1), a first connector (J1) connected with an intercom, and a second connector (J2) connected with the headset. The PTT controller is characterized in that: the PTT key (2) comprises a second switch (S2) and a third switch (S3), the second switch (S2) is connected between a MIC-OUT pin of the first connector (J1) and a MIC-IN pin of the second connector (J2) in series, the third switch (S3) is connected between a PTT pin of the first connector (J1) and a microphone (M1) of the headset, and the third switch (S3) is connected behind the first switch (S1) in series and is in parallel connection with the second switch (S2). The PTT controller has the advantages of simple circuit structure and easy realization, and can be used in a plurality of intercom headsets.

Description

technical field [0001] The present invention relates to an electronic controller, more specifically, relates to a general PTT (Push-to-Talk) controller for a headset on a walkie-talkie. Background technique [0002] Since the walkie-talkies and headsets currently on the market are PTT (Push-to-Talk) control to send and receive voice calls corresponding to the circuits of the walkie-talkies themselves, that is to say, the working circuit of the PTT controller on the headset line is unique. The result of this is that when users or manufacturers match earphones with different brands or models of walkie-talkies, due to the one-to-one correspondence, there are many types of earphones or PTT controllers, which greatly reduces the cost. It also increases and is inconvenient to manage. Contents of the invention [0003] The present invention is aimed at the improvement of the prior art, and the technical problem to be solved is to provide a universal PTT controller for a walkie-t...
