Detailed Implementation

[0029] 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.

[0030] Example 1:

[0031] Referring to Figures 1-6, a quick-connect wireless microphone is characterized by comprising a microphone body 1, a display screen 2, a power button 3, a mute button 4, and a page-turning button 5. The display screen 2 is used to display the power on / off status of the microphone body 1. The power button 3 is used to control the power on / off status of the microphone body 1. The mute button 4 can mute the microphone. The page-turning button 5 can turn pages of the display screen. The two page-turning buttons 5 are symmetrically arranged on the outer side of the microphone body 1.

[0032] It also includes two volume control buttons 6, which are symmetrically arranged, and a laser pointer button 14, which is located at the front end of the microphone body 1;

[0033] It also includes a headphone jack 7, which is used to connect wired audio devices;

[0034] The microphone body 1 is equipped with an NFC transmitting coil inside, which can quickly connect with active NFC, passive NFC, or external NFC 15 by simply touching them together.

[0035] The microphone body 1 is equipped with a wireless signal transmitter 16 and a page turner transmitter 17.

[0036] Working Principle: The display screen 2 on the front of the microphone body 1 can effectively display the battery level of the microphone body 1 and the connection status with external devices. The power button 3 on the front of the microphone body 1 can control the on / off state of the microphone body 1. The mute button 4 can mute the microphone at any time during presentations after it is connected to an external speaker. When the magnetic USB plug 13 is inserted into the computer, the staff can use the page-turning button 5 to turn pages in the PPT on the computer. The staff can press the laser pointer button 14 to generate a laser from the laser head 10 on the top of the microphone body 1, making it more convenient for the staff to teach. The narration device 9 on the top of the microphone body 1 can effectively facilitate the staff's presentation. The wireless signal transmitter 16 and page-turning device transmitter 17 inside the microphone body 1 can effectively transmit signals to the connected devices. Electronic devices are used for control, and the wireless signal transmitter 16 can also connect to external devices via Bluetooth. Then, staff can connect to an external extended microphone through the headphone jack 7, and switch between internal and external microphone input through the external wired extended microphone connected to the headphone jack 7. After that, staff can insert the wired headphone connector into the headphone jack 7 to establish a wired connection. After checking that the plug is firmly inserted into the audio input or output interface of the microphone body 1, staff can then set the headphone microphone as the recording input source for recording and explanation. At the same time, the explanation device's recording function can also extract the audio, generate meeting minutes and text through AI transcription, and translate the text into other foreign languages. The audio of the explanation device can be transmitted in real time to mobile phones or internet-connected terminal devices, such as mobile phones or internet-connected computers, for translation and text transcription. The audio recorded by the explanation device can be extracted through data and sent to mobile phones or internet-connected computers for AI transcription, text organization, or translation.

[0037] Example 2:

[0038] Please refer to Figures 1-6 for details. It also includes a connection hole 8, which is a TYPE-C interface.

[0039] It also includes a narrator 9, a laser head 10, and a REST button 11, and the narrator 9, laser head 10, and REST button 11 are arranged side by side at the front end of the microphone body 1;

[0040] It also includes a card slot 12 and a magnetic USB plug 13, and the magnetic USB plug 13 and the card slot 12 are magnetically connected;

[0041] Working principle: The microphone body 1 can be charged via the connection port 8 on the right side. Connection port 8 is Type-C, which can be used for recording retrieval. After connecting the microphone body 1 to an external speaker, the staff can speak through the narrator 9. The REST button 11 is the power button; a long press turns the microphone on / off, while a short press quickly disconnects and pairs it with the speaker. The slot 12 at the bottom of the microphone allows the magnetic USB plug 13 to be inserted, and the staff can also insert the magnetic USB plug 13 into a computer port. This allows for connection with a computer. Once the USB plug 13 is inserted into the computer, the computer and microphone body 1 are connected. After connection, third-party software on the computer can be used to transcribe or translate the audio recordings in the microphone body 1 to improve usability. At the same time, the magnetic USB plug 13 and the card slot 12 are magnetically connected, so the magnetic USB plug 13 can be easily engaged in the microphone body 1. Then, the external NFC 15 set at the rear of the microphone body 1 allows the microphone body 1 to quickly connect to an external speaker by simply touching it.

[0042] The staff holds the microphone body 1 and makes the external NFC 15 at the rear of the microphone body 1 contact or abut with the built-in NFC 15 in the external speaker or headphones. This causes the electric field and magnetic field of the external NFC 15 at the rear of the microphone body 1 to alternately convert energy during the process of propagating from the transmitting antenna to the built-in NFC in the speaker or headphones and receiving the antenna. During the conversion, they reinforce each other, which allows the microphone body 1 to quickly connect with the speaker or headphones.

[0043] The NFC coil inside the microphone body allows the microphone body to quickly connect to active or passive NFC (external NFC) devices by simply touching them together.

[0044] NFC is a short-range wireless communication technology that allows electronic devices to exchange data when they are close to each other. It works on the basis of RFID (Radio Frequency Identification) technology, and enables fast connection and data transfer between devices by integrating inductive card readers, inductive cards and point-to-point communication functions on a single chip.

[0045] Working principle:

[0046] NFC technology operates at a frequency of 13.56 MHz, with a communication distance typically within 4 centimeters. It has two operating modes:

[0047] Active mode: In this mode, both NFC devices generate their own radio frequency fields and communicate with each other. Each device generates a radio frequency field when sending data and turns off the radio frequency field when receiving data.

[0048] Passive mode: Only one device generates the radio frequency field, and another device uses this radio frequency field to communicate. Passive mode devices usually do not need an internal power supply, but are powered by the radio frequency field of an external device.

[0049] The external NFC is in passive mode. An active NFC device (A, the guide, with power and NFC coil) is brought close to a passive NFC tag (B, an external NFC tag with a passive induction coil). The external NFC tag (B) carries information for quick pairing between A and C. C is an audio playback device that plays back the guide's audio (C is tentatively set as a speaker, but can actually be a speaker, headphones, or other sound playback device). When A is close to B, the quick wireless pairing connection between A and C is activated, solving the traditional pairing problem between two wireless devices.

[0050] The traditional pairing process involves several steps, including enabling pairing, searching for devices, and confirming pairing. Both devices must perform these steps simultaneously, which is quite cumbersome. By pre-writing C's pairing name information into B (an external NFC tag), A can quickly obtain C's pairing information and automatically connect to C whenever A and B are close together.

[0051] In actual use, the distance between speaker C and the guide A is far: A is on the classroom podium, and C is at the back of the classroom or on the classroom wall. To connect them, both A and C need to be put into pairing mode, or C needs to be put into pairing mode using wireless commands (infrared pairing). Alternatively, A and C can be fixed to a fixed connection at the factory. However, if A is lost, the new guide D needs to be put into pairing mode and selected to connect with C, which is complicated and not quick.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
