[0003] Normally, classrooms are equipped with microphones to collect and amplify the teacher's voice so that students in the classroom can hear the teacher's teaching content more clearly, and the teacher no longer needs to speak loudly when teaching, which is very friendly to both teachers and students. Secondly, wireless microphones are more popular because they are free from the constraints of communication lines. However, with the popularization of modern smart classrooms, the number of wireless microphones has increased, and classrooms are close to each other. Wireless microphones in classrooms are generally difficult to manage, and the phenomenon of misplacing is serious. In addition, when common U-end microphones are used in classrooms, there will be frequency crosstalk, causing the lecture sound to come out of the speakers in other classrooms. In addition, wireless microphones do not have the ability to lock with the base, and any user can use them, further increasing the difficulty of microphone management. Summary of the invention

[0043] Example 1

[0044] like Figure 1As shown, a teaching microphone centralized management system involved in Example 1 of the present application includes: a microphone 100, a base 200 and a sound reinforcement host 300, wherein the first processor 101 of the microphone 100 can realize wireless communication after frequency matching with the 2.4G transceiver module 2 202 of the base 200 through the 2.4G transceiver module 1 103, and the second processor 201 of the base 200 realizes communication with the sound reinforcement host 300 through a communication line and an audio line, and can forward the audio collected by the pickup 102 of the microphone 100 to the sound reinforcement host 300 for sound amplification processing. The sound reinforcement host 300 is connected to the PC host 400 through a communication line, which is used to realize the forwarding of control instructions such as PPT page turning, mouse control, digital laser, annotation and magnifying glass on the microphone 100 to the PC host 400, so that the PC host 400 performs corresponding actions, thereby realizing the functions of PPT page turning, mouse control, digital laser, annotation and magnifying glass through the microphone 100.

[0045] Specifically, the user can enter the following modes through the first control button 106 on the microphone 100:

[0046] Mode 1-traditional laser: the gyroscope 110 is turned off all the time. When the button is pressed, the laser light 111 on the head of the microphone 100 is turned on; when the button is released, the laser light 111 is turned off.

[0049] Mode 4 - mouse control mode: when pressed, the gyroscope 110 is activated to send movement track data; when released after 1 second, the movement track data is stopped. When released within 1 second, the left mouse button click effect is triggered.

[0050] Mode 5-Annotation Mode: After entering this mode, the gyroscope 110 remains activated and sends movement trajectory data. When pressed, the left mouse button long press effect is triggered; when released, the left mouse button long press is turned off.

[0051] like Figure 5 As shown, in this embodiment, two microphones 100 are configured on a base 200. It should be noted that the number of microphones 100 configured on the base 200 can be set as needed, for example, 1, 2, 3, 4, etc. microphones 100 can be configured on a base 200. Figure 2As shown, the microphone 100 has a first processor 101 and a microphone 102, a 2.4G transceiver module 1 103 and a rechargeable battery 104 electrically connected to the first processor 101, wherein the microphone 102 is used to collect sound signals in the space and convert them into electrical signals, the 2.4G transceiver module 1 103 is used to realize wireless communication with the 2.4G transceiver module 2 202 in the base 200, and the rechargeable battery 104 is used to provide power for the microphone 100. The rechargeable battery 104 can be a lithium battery, a lithium oxygen battery, a lithium magnesium battery, etc. The microphone 100 also has a first display screen 105 and a plurality of first control buttons 106, wherein the first display screen 105 is used to display classroom information of the base 200 to which the microphone 100 is connected, the remaining power of the microphone 100, and The volume information of the sound reinforcement host 300, etc., a charging connector 107 is embedded at one end of the microphone 100, and the charging connector 107 includes a first charging contact 1071 and a first detection contact 1072. The rechargeable battery 104 of the microphone 100 can be charged through the first charging contact 1071, and the charging automatically stops when the battery is fully charged. The first detection contact 1072 is electrically connected to the first processor 101, and the first processor 101 can determine the plug-in status of the microphone 100 based on whether the first detection contact 1072 forms a closed loop. A lock slot 108 is provided on the side wall of one end of the microphone 100 close to the charging connector 107, the first display screen 105 and the first control button 106 are both electrically connected to the first processor 101, and the charging connector 107 is electrically connected to the rechargeable battery 104.

[0052] like Figure 2 As shown, the microphone 100 has a built-in gyroscope 110, which can detect the movement trajectory of the microphone 100 to realize functions such as mouse control, digital laser, and magnifying glass. A laser light 111 is set at one end of the microphone 100, and the laser light 111 can realize laser pointer and cooperate with the gyroscope 110 to realize functions such as digital laser. The gyroscope 110 and the laser light 111 are both electrically connected to the first processor 101. The magnetic suction component 205 includes a magnet 2051 and a magnetic suction body 2052. Figure 6 and Figure 7As shown, both ends of the charging connector 107 are provided with magnetic bodies 2052, wherein the magnetic bodies 2052 can be attracted by the magnets 2051 provided on the charging base 204, so that the charging connector 107 and the charging base 204 can be adsorbed together by the direct magnetic attraction of the magnets 2051 and the magnetic bodies 2052, so as to ensure the stable connection between the charging connector 107 and the charging base 204 during the charging process. The microphone 100 also has a TYPE-C charging interface 109, which is electrically connected to the rechargeable battery 104. The TYPE-C charging interface 109 serves as a backup charging port for the microphone 100. In special circumstances such as when the microphone 100 runs out of power during use, a power bank or other power source can be used to charge the rechargeable battery 104 of the microphone 100 through the TYPE-C charging interface 109.

[0053] like Figure 3 As shown, the base 200 has a second processor 201 and a 2.4G transceiver module 202 electrically connected to the second processor 201, wherein the 2.4G transceiver module 202 is used to pair with the 2.4G transceiver module 1 103 of the microphone 100 to achieve wireless communication with the microphone 100, such as Figure 5 As shown, the base 200 is provided with at least one slot 203 adapted to the microphone 100, wherein the slot 203 is used to insert the microphone 100, and in order to enable the charging connector 107 to maintain an effective electrical connection with the charging base 204, the slot 203 is adapted to the size of the microphone 100, that is, the inner cross-section of the slot 203 is slightly larger than the outer cross-section of the microphone 100, so that the microphone 100 can just be inserted into the slot 203. In this embodiment, as shown in FIG. Figure 7 and Fig. 9 As shown, the lock slot 108 of the microphone 100 protrudes from the microphone 100, so the slot 203 needs to reserve a groove 212 that matches the protruding lock slot 108. The bottom of the slot 203 is provided with a charging base 204 that matches the charging connector 107. After the charging base 204 is connected to a power source, the charging connector 107 is electrically connected to the charging base 204 after the microphone 100 is inserted into the bottom of the slot 203 to realize the function of charging the rechargeable battery 104. Figure 8As shown, the charging base 204 includes a second charging contact 2041 and a second detection contact 2042, wherein the second charging contact 2041 is used to charge the rechargeable battery 104 of the microphone 100 by contacting the first charging contact 1071. The second detection contact 2042 is electrically connected to the second processor 201, and the second processor 201 determines whether the charging interface is plugged into the charging base 204 by detecting whether the first detection contact 1072 and the second detection contact 2042 are in contact to form a closed loop. For example, two first detection contacts 1072 and two second detection contacts 2042 are provided. If a closed loop is detected between the first detection contact 1072 and the second detection contact 2042 after the microphone 100 is inserted into the slot 203, it is determined that the charging interface has been inserted into the charging base 204. At this time, the rechargeable battery 104 is being charged. If it is detected that no closed loop is formed between the first detection contact 1072 and the second detection contact 2042, it is determined that the charging interface is not inserted into the charging base 204. At this time, the rechargeable battery 104 is not being charged, so that the plug-in contact 112 composed of the first detection contact 1072 and the second detection contact 2042 can be used to determine whether the microphone 100 is inserted and whether the microphone 100 is inserted in place, and the change of the plug-in state and the state of the electric lock 206 can be used to detect malicious damage such as misplugging or forcibly plugging out the microphone 100 when the microphone 100 is locked. The slot 203 is An electric lock 206 that cooperates with the lock slot 108 is embedded on the side, wherein the electric lock 206 has a lock tongue 2061 that can be extended into the lock slot 108. After the microphone 100 is inserted into the bottom of the slot 203 and the lock tongue 2061 is inserted into the lock slot 108, the microphone 100 can be pulled out a specified distance. In other words, the length of the lock slot 108 is greater than the thickness of the lock tongue 2061, so that after the microphone 100 is inserted into the bottom of the slot 203 and the electric lock 206 is in a locked state, the microphone 100 can still be pulled out a certain distance, so that the mis-pulling operation of the microphone 100 can be detected according to the state of the mis-pulling contact and the electric lock 206. The base 200 is also provided with a second display screen 207 and a plurality of second control buttons 208, wherein the second display screen 207 can be used to display classroom information where the base 200 is located (for example: class number, classroom number, etc.), power information of the microphone 100, number of the microphone 100 and status information of the corresponding electric lock 206 (for example: electric lock 206 of microphone No. 1 100 is locked, electric lock 206 of microphone No. 1 100 is opened, etc.), etc. The second display screen 207, the second control buttons 208, the charging base 204 and the electric lock 206 are all electrically connected to the second processor 201.

[0054] like Fig. 9 and Fig.10As shown, in order to further detect whether the microphone 100 that matches the slot 203 is inserted into the slot 203, a mechanical limit switch 209 is embedded on one side of the slot 203. When the microphone 100 is inserted into the slot 203, the mechanical limit switch 209 can be pushed to operate, thereby generating an electrical signal and transmitting it to the first processor 101, thereby determining that the microphone 100 is inserted into the slot 203. Combined with the plug-in contact 112, it can more accurately identify that the inserted microphone is the microphone 100. For example, if a large amount of foreign matter such as chalk or eraser falls into the slot 203, it may cause the mechanical limit switch 209 to operate. At this time, the second processor 201 may mistakenly determine that the "microphone 100" is inserted into the slot 203. However, foreign matter such as chalk or eraser falling into the slot 203 will not cause the plug-in contact 112 to form a closed loop, thereby identifying that the inserted microphone is not the microphone 100, and a prompt sound can be emitted through the speaker 210 to prompt.

[0055] In a further embodiment, in order to issue a prompt sound and an indication signal, the base 200 is provided with a speaker 210 and an indicator light 211 corresponding to the slot 203. The speaker 210 and the indicator light 211 are both electrically connected to the second processor 201. When the microphone 100 is not inserted into the bottom of the slot 203, the microphone 100 is accidentally pulled out, or a foreign object falls into the slot 203, the second processor 201 can control the speaker 210 to issue a corresponding prompt sound prepared in advance to remind the user. In addition, the state of the electric lock 206 can be judged by the color of the indicator light 211. For example, when the electric lock 206 under the corresponding microphone 100 is in a locked state, the indicator light 211 corresponding to the microphone 100 emits a red light. When the electric lock 206 under the corresponding microphone 100 is in an open state, the indicator light 211 corresponding to the microphone 100 emits a green light, so that the user can judge the locking state of the microphone 100 by the color of the indicator light 211.

[0056] like Figure 4 As shown, the sound reinforcement host 300 is communicatively connected with the base 200. The sound reinforcement host 300 also has a communication interface for connecting to the PC host 400 and a communication module for communicating with the background management platform 500. The sound reinforcement host 300 has a user interaction module 301, an effector module 302, an external interface module 303 and a main business module 304.

[0059] Up / Down Button: In the volume adjustment interface, use the up / down buttons to adjust the volume. A short press changes the volume by 1, and a long press quickly increases or decreases the volume. Press and hold the up / down button and the SET button for 5 seconds at the same time: the PA host 300 sends a classroom number modification command to the base 200, changing the current classroom number on the base 200 to the classroom number of the PA host 300;

[0060] Power indicator light: turns white after power on;

[0061] Microphone connection indicator light: lights up white when the corresponding microphone 100 is turned on and connected successfully.

[0062] Effector module 302: supports 3-input and 4-output audio. Custom configuration can be used on each output channel to mix any input sound signal. After mixing, the audio can be EQ-adjusted with multiple parameters such as treble, midrange, bass, reverberation, etc.

[0063] The external interface module 303 is used to unify and regularize the interfaces that the internal modules need to output to the outside, such as: mixing output interface, wireless microphone 100 output interface, wired microphone 100 output interface, wired microphone 100 input interface, audio input interface, communication input interface, communication output interface, PPT page turning interface, microphone 100 control interface, network input interface, aviation plug, microphone 100 reset, power input interface, etc.

[0064] The main business module 304 includes a single-chip microcomputer sub-module, a power amplifier sub-module, and a USB-HUB sub-module.

[0065] The single-chip microcomputer submodule is the main control part of the CPU, which is mainly used to respond to and process all interactive instructions, such as: various function buttons on the microphone 100, various function settings in the interactive interface of the first display screen 105, external control instruction response, etc. Support output of PPT page turning and play / stop play instructions from the microphone 100 to the PC host 400 through the USB-module; generate a standard pickup 102 device in the PC host 400 system to facilitate various software applications to obtain the sound of the microphone 100; communicate with the configuration software to help the software complete the parameter configuration of the microphone 100. Conduct network communication with the server of the background management platform 500, and report various status information: the status of the microphone 100 receiving the amplification host (whether it is turned on, the signal quality of the microphone 100, the current number of microphones 100, the classroom number, hardware information, firmware information, MAC address, network information, effect settings), the status of the base 200 (whether it is connected, the homing state, the locked state), and the status of the microphone 100 (whether it is turned on, the power state, and the classroom number). According to the instructions of the background management platform 500, the following actions are performed: modifying the communication frequency band, modifying the classroom number (including modifying the classroom number of the microphone 100, the base 200 and the speaker host), modifying the effector settings, unlocking the microphone 100, etc.

[0066] Amplifier submodule: It can amplify the audio processed by the effector module 302, so as to achieve the purpose of directly connecting the sound signal to the passive speaker.

[0067] USB-HUB submodule: various USB signals can be aggregated and transmitted to the PC host 400 via a USB cable, thereby completing the interactive communication between the PC host 400 and the sound amplification host.

[0068] Example 2

[0069] like Fig.11 As shown, a teaching microphone centralized management method involved in Embodiment 2 of the present application includes:

[0070] S100, the first processor 101 automatically opens the electric lock 206 during the preset class period so that the microphone 100 can be taken out, that is, the user only needs to set the class time period in advance on the background management platform 500, and the electric lock 206 will automatically open during the class time period to unlock the microphone 100, so that the teacher can directly take out the microphone 100 during the class without manual unlocking operation, which is very convenient;

[0071] S200, after the teacher takes out the microphone 100 from the slot 203, the plug-in contact 112 detects that the microphone 100 has been unplugged, and the first processor 101 automatically controls the microphone 100 to automatically turn on. After turning on, the frequency button in the first control button 106 sends a frequency-binding instruction to the first processor 101. After receiving the frequency-binding instruction, the first processor 101 performs frequency-binding with the 2.4G transceiver module 2 202 of the base 200 through the 2.4G transceiver module 1 103;

[0072] S300, after the frequency matching is completed, the second processor 201 in the base 200 automatically sends the classroom number (i.e., teacher information) of the base 200 to the 2.4G transceiver module 2 202 through the 2.4G transceiver module 1 103, and the first processor 101 receives the classroom information of the base 200 and the sound reinforcement host 300, and displays the classroom information on the first display screen 105. According to the classroom information displayed on the first display screen 105 and the second display screen 207, it can be checked whether the classroom information of the base 200 and the microphone 100 is consistent, thereby effectively avoiding the microphone 100 from being taken or placed incorrectly;

[0073] S400, the first processor 101 sends the collected audio signal to the base 200 through the 2.4G transceiver module 1 103, so as to transmit the audio signal to the sound amplification host 300 through the base 200 for sound amplification. Specifically, the microphone 102 converts the clipped sound signal into an electrical signal and sends it to the first processor 101, which is sent to the 2.4G transceiver module 2 202 by the 2.4G transceiver module 1 103, and the second processor 201 forwards the received audio signal to the sound amplification host for sound amplification.

[0074] In order to save energy, if it is detected that there is no voice input within a first specified time (for example: 10 seconds, 20 seconds or 25 seconds, etc.), the microphone 100 automatically enters a low-power standby state. If the low-power standby state lasts for a second specified time (for example: five minutes, eight minutes or ten minutes, etc.), the microphone 100 automatically shuts down.

[0075] S500. During the preset non-class period, the mechanical limit switch 209 detects that the microphone 100 has been inserted and the plug-in contact 112 detects that the charging connector 107 has been inserted, and the corresponding electric lock 206 is automatically locked. That is, after class, the teacher inserts the microphone 100 into the slot 203, and the microphone 100 will push the mechanical limit switch 209 to produce an action. The mechanical limit switch 209 converts the action into an electrical signal and sends it to the first processor 101. At this time, the first processor 101 detects that the microphone 100 is inserted into the slot 203, and can determine whether the microphone 100 is inserted in the slot 203 based on the electrical signal, and further determine whether the microphone 100 is inserted in place by detecting whether the plug-in contact 112 forms a closed loop.

[0076] After the microphone 100 is inserted, if the plug-in contact 112 does not detect that the charging interface is inserted, a first voice prompt instruction is generated and sent; if the plug-in contact 112 detects that the charging interface is inserted, a second voice prompt instruction is generated and sent.

[0077] For example: if a teacher inserts the microphone 100 into the slot 203 after class, but the microphone 100 is not inserted into the bottom of the slot 203, so that the charging interface fails to be effectively connected to the charging base 204 (that is, the charging interface fails to form an electrical connection with the charging base 204, and the charging base 204 cannot charge the rechargeable battery 104 through the charging interface), at this time, the plug-in contact 112 does not detect that the charging interface is inserted into the charging base 204, then a second voice prompt instruction is generated and sent to the speaker 210 to issue a prompt tone of "the microphone 100 is not plugged in properly and cannot be charged"; if a teacher inserts the microphone 100 into the slot 203 after class, and the plug-in contact 112 detects that the charging interface is inserted into the charging base 204, then a first voice prompt instruction is generated and sent to the speaker 210 to issue a prompt tone of "the microphone 100 is plugged in and is charging".

[0078] In this embodiment, whether the microphone 100 meets the locking and charging conditions can be determined based on whether the error contact formed by the first detection contact 1072 and the second detection contact 2042 forms a loop.

[0079] When the electric lock 206 is in a locked state and the mechanical limit switch 209 detects that there is a microphone 100, if the plug-in contact 112 detects that the charging interface is switched from being inserted to not inserted, a third voice prompt instruction is generated and sent. For example, the mechanical limit switch 209 is squeezed by the microphone 100 in the slot 203 to generate an action and generate an electrical signal. The second processor 201 detects that there is a microphone 100 in the slot 203 according to the electrical signal. Initially, the plug-in contact 112 detects that the charging interface has been inserted into the charging base 204, and the electric lock 206 is in a locked state. At a certain moment, the plug-in contact 112 detects that the charging interface has been inserted into the charging base 204. The pull-out contact 112 detects that the charging port has changed from being inserted to being unplugged, and the electric lock 206 is in a locked state at this time. Then, the second processor 201 determines that someone has accidentally pulled out the microphone 100 in the locked state, and generates a third voice prompt instruction and sends it to the speaker 210, so that the speaker 210 issues a voice prompt of "Microphone 100 is locked, do not remove microphone 100", thereby being able to detect the mis-pulling of the microphone 100 based on whether the mis-pulling contact forms a closed loop and the state of the mechanical limit switch 209, thereby preventing damage to the microphone 100 or the base 200 caused by multiple mis-pulling.

[0080] Receive control instructions from the microphone 100, and send the control instructions to the PC host 400 to control the PC host 400 to perform corresponding actions, wherein the control instructions include at least one of the following: PPT page turning, mouse control, digital laser, annotation, and magnifying glass. The functions of PPT page turning, mouse control, digital laser, annotation, magnifying glass, and laser pointer are organically integrated into the microphone 100. The teacher can walk around the classroom with the microphone 100 at will, and does not need to return to the PC host 400 when performing operations such as PPT page turning and mouse control, thereby improving the flexibility of teaching. Specifically, the user can enter the following modes through the first control button 106 on the microphone 100:

[0081] Mode 1-traditional laser: the gyroscope 110 is turned off all the time. When the button is pressed, the laser light 111 on the head of the microphone 100 is turned on; when the button is released, the laser light 111 is turned off.

[0082] Mode 2 - Digital Laser: When pressed, the gyroscope 110 is activated to send movement track data; when released, the movement track data is stopped.

[0083] Mode 3 - magnifying glass: when pressed, the gyroscope 110 is activated to send movement track data; when released, the movement track data is stopped from being sent.

[0084] Mode 4 - mouse control mode: when pressed, the gyroscope 110 is activated to send movement track data; when released after 1 second, the movement track data is stopped. When released within 1 second, the left mouse button click effect is triggered.

[0085] Mode 5-Annotation Mode: After entering this mode, the gyroscope 110 remains activated and sends movement trajectory data. When pressed, the left mouse button long press effect is triggered; when released, the left mouse button long press is turned off.

[0086] In addition, the background management platform 500 can communicate with the sound reinforcement host 300. The background management platform 500 can also modify the communication frequency band, modify the effector settings, unlock the microphone, modify the classroom number of the microphone 100, base 200 and sound reinforcement host 300, set the get out of class time period, and other operations.

[0087] In this embodiment, by realizing real-time communication with the background management platform 500, the classroom information on the background management platform 500 is automatically synchronized to the local, and the classroom information is automatically displayed on the display screens of the base 200 and the microphone 100, so as to realize orderly and visual management of the microphone 100, the base 200, the sound reinforcement host 300 and other equipment, thereby effectively avoiding the phenomenon of wrongly taking or misplacing the microphone 100, and realizing the functions of return detection, mispulling detection and automatic locking and automatic unlocking of the microphone 100 during a specified time period through the mispulling contact and the mechanical limit switch 209, and realizing the call and setting of the return detection, mispulling detection and automatic locking and automatic unlocking of the microphone 100 during a specified time period from the PC host 400, so as to help the classroom administrator to realize the automatic locking of the microphone 100 outside of class time and the automatic unlocking of the microphone 100 during class time, thereby reducing the pressure of operation and maintenance and reducing the operation.
