Description

A hand microphone that realizes remote intercom, voice control and load charging of mobile phones

technical field

The utility model relates to a hand microphone for realizing remote intercom, voice control and load charging of a mobile phone.

Background technique

The existing hand microphone technology and design can only be satisfied with the traditional walkie-talkie or PTT special walkie-talkie. At present, the emerging walkie-talkie software used on the intelligent platform does not have a hand microphone that can be matched with it. The existing PTT special walkie-talkie The mobile microphone cannot be controlled with the walkie-talkie software on the mobile phone or smart device, and it does not have its own power supply, cannot amplify the sound signal, and cannot charge the mobile phone or smart device.

Contents of the invention

The purpose of the utility model is to propose a mobile microphone that realizes remote intercom, sound control and load charging of mobile phones, so as to solve the problem that the intercom on the existing mobile phone or smart device cannot be used to send calls, playback control and volume can only be controlled by external devices. Playing through the built-in speaker leads to problems that the volume cannot meet outdoor needs, the operation and delivery of calls must be done through the buttons on the mobile phone or smart device, and the mobile phone or smart device cannot be charged.

This utility model proposes the hand microphone that realizes the remote intercom, sound control and load charging of the mobile phone. It has an organic body, a 3.5mm earphone plug, a main board installed in the body, a loudspeaker, a microphone, a power battery, a signal converter, micro USB, USB interface, characterized in that the phone button, microphone, and loudspeaker on the body are connected to the 3.5mm headphone plug, the loudspeaker, micro USB interface, USB interface, and signal converter are connected to the power battery, and the buttons on the body pass through The 3.5mm headphone plug realizes the control of the smart device software; the charging function realizes the charging of the smart device through the connection of the micro USB interface.

The body is connected with a first-stage amplifier circuit to adjust the volume when the hand-microphone intercom is low and the other party cannot hear it.

The utility model works as follows:

1) Turn on the power switch 7 to activate the hand microphone;

2) Insert the 3.5mm plug of the hand microphone into the 3.5mm jack of the mobile phone or other smart devices, open the walkie-talkie software or similar software, and debug the software; when you tap or hold the send button, the call starts; when you click again Or release the call key, and the call ends; in addition, there is a prompt sound when the call starts, and a prompt sound when the call ends.

After adopting the above structure, compared with the prior art, the utility model has the advantages of: amplifying the voice of the walkie-talkie and similar software of smart devices such as mobile phones through external devices, solving the problem of relying on the built-in loudspeakers of mobile phones or smart devices. Can not meet the needs of use, and make it easier to send calls, you can send calls without touching your mobile phone or smart device, especially when the device can only be placed in a backpack or underwear, it can especially reflect the utility model Value, the utility model takes into account the power consumption of the mobile phone or smart device software when it is running, and adds a charging device at the same time, which solves the problems of insufficient power, time-consuming charging and inability to work when the mobile phone or smart device uses the software.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1-6, the switch K2 is responsible for answering, hanging up, and intercom buttons for the mobile phone. Press the first time to control the mobile phone to open the WeChat function, and press the second time for the intercom function. The required function, of course, this function must be supported by software settings.

Switch K1 is the power switch of the machine.

The mobile phone jack is the jack for charging the mobile phone.

The microc is the port for charging the microphone.

The first level of amplification in the dotted box in Figure 1 is designed for the situation where the voice of the microphone is low when talking to the other party and the other party cannot hear it.

When K1 is pressed, the hand microphone is powered on and starts to work. When K2 is pressed, the mobile phone enters the intercom state and automatically turns on and starts to send sound signals. The sound signal MIC2 microphone output is coupled to the fourth pin of the plug through C7 capacitor and then reaches Inside the mobile phone; when K2 is released, it is in the receiving state. The signal sent by the other party passes through the plug first, and the second pin outputs to the machine through C1, R3, C2, R4 and enters the inside of the PAM840 for amplification. The amplified sound signal enters the PAM840 Pins 1 and 3 and pins 16 and 18 are output to speakers or headphones respectively. The sound control of this unit is controlled by R1 and R2 respectively to control the speaker and earphone. When K2 is pressed again quickly, various functions will be set according to the software of the mobile phone.

The first-stage amplifier circuit is a pre-amplifier circuit for sending sound signals from the MIC cylinder microphone, and this circuit can be added to the body circuit according to the actual use.

The battery of this circuit uses a high-current lithium battery, which not only supplies power for the hand microphone, but also provides mobile power for the mobile phone. The microc port is the charging port for the hand microphone, which is provided by an external 5V DC power supply.

Parts and symbols not mentioned are as above.

Such hand microphones have the following specific effects:

First, it solves the problem of high cost of PTT walkie-talkie. At present, the price of a PTT walkie-talkie is about 2,000 yuan, but after the present invention is put into the market, it is only about 300 yuan;

Second, it solves the problem of distance limitation of traditional walkie-talkies. In the actual test, the utility model can realize the intercom function as long as there are 3G or above signals. Several parties are in Guangdong, can clearly hear each other's voice, and can quickly reply through the button of the present invention.

Third, it solves the problem that the volume of the walkie-talkie software can only be played through the speaker that comes with the mobile phone, and the volume is not enough, and it is inconvenient to press the screen of the mobile phone when replying to the conversation; the utility model is placed on the shoulder, and the voice of the other party can be clearly heard , and the volume can be adjusted according to needs. After pressing the button of the invention, the user can communicate with the other party in time, which saves the time of taking out the mobile phone and pressing the button on the mobile phone to reply.

Fourth, it solves the problem of high power consumption and time period when the mobile phone uses the walkie-talkie software; in actual use, depending on the battery capacity of the mobile phone, the operating system, the frequency of use, etc., the length of time that can be used varies. When charging, use another charging line matched with the utility model to connect the mobile phone and the utility model at the same time, realizing the effect of intercom while charging.

Fifth, the utility model is especially suitable for the real-time intercom between professionals such as traffic police and criminal police in the field and remote command centers and other communication parties.
