Description

Technical Field

[0001] This utility model relates to the field of radio communication technology, specifically to an earphone microphone assembly with power indication. Background Technology

[0002] When a communication radio is in operation, the operator can only determine whether there is power output through the panel indicators, but cannot determine the actual signal power output. To diagnose transmitter malfunctions, there are usually three testing methods: first, using a power meter to test whether there is signal output; second, using a spectrum analyzer to test the radio signal; and third, using another radio to receive and test.

[0003] However, the above three methods have limited effectiveness and poor operability in practical use. The instruments are not portable and cannot be assigned to each terminal; when using wireless, there is no suitable standard antenna; and in case of failure, there is no other radio to assist in the testing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-3A headphone microphone assembly with power indication includes a speaker module 1, a microphone module 2, a PTT button 3, a power detection switch 4, LED indicator lights 5, and a handle 6. The speaker module 1 is located on the top of the handle 6, the microphone module 2 is mounted on the bottom rear end of the handle 6, the PTT button 3 is located on the right end of the microphone module 2, the PTT button 3 is embedded in the front end of the handle 6, and LED indicator lights 5 are equidistantly distributed on the upper front side of the handle 6. A power detection module 61 is located inside the handle 6, and the power detection module 61 also includes a detection module switch and a detection module circuit. The power detection module 61 is electrically connected to the LED indicator lights 5. The speaker module 1 is used to output audio, the microphone module 2 is used to input audio, the PTT button 3 is used to transmit signals, the power detection switch 4 is used to connect the detection circuit, and the power detection module 61 is used to realize power detection. It consists of a passive power detection device and is used to determine whether there is a signal output; it also indicates the signal strength in stages.

[0026] Example 2

[0027] The difference between this embodiment and embodiment 1 is that the power detection module 61 is composed of an active detection device, and other modules may optionally include circuit combinations that achieve the same function.

[0028] In summary, such as Figure 2 As shown, when the power detection switch 4 is in the off state, the headset microphone assembly can perform normal transmission and reception functions. When the power detection switch 4 is in the on state, the power detection module 61 is in working state. When the PTT button 3 is in the transmit state, and the headset microphone assembly is brought close to the antenna of the transceiver device, the LED indicator 5 on the back of the headset microphone assembly displays the output result. The first LED indicator from the left is lit when low power, the second LED indicator from the left is lit when medium power, and the third LED indicator from the left is lit when high power.

[0029] This example illustrates the working principle of this invention using a handle-type headset microphone assembly. Furthermore, when using a headset microphone assembly or similar device, the device designed according to this invention will still function normally.

[0030] Of course, this utility model can also be implemented using other transceiver terminals, such as a hand microphone, and the LED indicator light used as the detection output can also be a buzzer.

[0031] The headphone microphone assembly designed according to this utility model can quickly determine the actual output status of the transmitter, and the device is relatively simple, with low implementation cost, high reliability, and low maintenance cost.

[0032] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0033] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
