Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediary component present. Conversely, when a component is said to be "directly" connected to another component, there is no intermediary component.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Please see Figure 1 A screen mirroring device with a microphone system includes at least one wireless microphone body 1 and a screen mirroring device body 2;

[0024] The wireless microphone body 1 includes a sound pickup module 11, a first wireless connection module 12, and a first power supply module 13.

[0025] The power supply module 13 provides power to the microphone module 11 and the first wireless connection module 12 through the signal output terminal of the microphone module 11 and the first wireless connection module 12.

[0026] The main body 2 of the screen mirroring device includes a second wireless connection module 21, an audio and video processing module 22, and a connector 23. The signal input terminal of the second wireless connection module 21 is connected to the signal output terminal of the first wireless connection module 12, and the signal output terminal of the second wireless connection module 21 is connected to the signal input terminal of the audio and video processing module 22. The signal output terminal of the audio and video processing module 22 is connected to the connector 23, and the connector 23 is connected to an external audio and video playback device. Power is supplied to the second wireless connection module 21 and the audio and video processing module 22 through the connector 23.

[0027] The microphone module 11 is a microphone, and the first wireless connection module 12 and the second wireless connection module 21 are 2.4G.

[0028] The device can be one of the following: a wireless module, a Bluetooth module, a UHF module, or a 5.8G wireless module. The wireless microphone unit 1 and the screen mirroring unit 2 can automatically select the optimal connection method. The first power supply module 13 is a rechargeable battery. The audio / video processing module 22 can perform audio amplification, noise reduction, echo cancellation, and equalization adjustments. The connector 23 can be a USB or HDMI high-definition male connector, plugged into a TV or screen, and connected to an external power source to provide power to the second wireless connection module 21 and the audio / video processing module 22.

[0029] When a meeting or teaching session is held, the audio pickup module 11 acquires the user's audio information and sends it to the first wireless connection module 12. The first wireless connection module 12 then sends the audio information to the second wireless connection module 21 of the screen sharing device 2. The second wireless connection module 21 sends the received audio information to the audio and video processing module 22. The audio and video processing module 22 processes the audio information and then sends it to the television or conference screen for playback via the connector 23.

[0030] Thus, a screen mirroring device with a microphone system is provided with a first wireless connection module 12 and a second wireless connection module 21 on the wireless microphone body 1 and the screen mirroring device body 2, respectively. The wireless microphone body 1 is connected to the screen mirroring device body 2 wirelessly. The audio information collected by the pickup module 11 of the wireless microphone body 1 is sent to the screen mirroring device body 2 through the first wireless connection module 12 and the second wireless connection module 21. Since the screen mirroring device body 2 is plugged into the TV or conference screen through the connector 23, the acquired audio information is output through the audio and video processing module 22 and played synchronously on the TV or conference screen. The TV or conference screen serves as a unified audio and video output terminal, eliminating the need to connect additional speakers to play audio information, making it more convenient to use and saving meeting or teaching costs to a certain extent.

[0031] In one embodiment, the screen mirroring device body 2 further includes an expansion female connector 25, which is electrically connected to the audio and video processing module 22; the expansion female connector 25 is a TP-YE-C female connector or a USB female connector.

[0032] In this way, the audio information processed by the audio / video processing module 22 can be sent to other devices via the expansion port 25. For example, the data can be transferred to a computer for storage.

[0033] In one embodiment, the main body 2 of the screen mirroring device further includes a storage module 26, the signal input terminal of the storage module 26 being connected to the signal output terminal of the audio and video processing module 22.

[0034] In this way, by setting up the storage module 26, when the audio information transmission is abnormal, the audio information processed by the audio and video processing module 22 can be cached on the storage module 26. After the transmission is restored, the audio information stored in the storage module 26 can be retrieved and transmitted to the audio and video processing module 22.

[0035] In one embodiment, the audio and video processing module 22 includes an audio and video marking unit and an audio and video selection unit. The signal output terminal of the audio and video marking unit is connected to the signal input terminal of the audio and video selection unit, and the signal output terminal of the audio and video selection unit is connected to the connector.

[0036] Thus, if two wireless microphone bodies 1 are connected to the screen mirroring unit 2, the audio / video marking unit needs to mark the audio information transmitted by the different wireless microphone bodies 1. The audio / video selection unit then selects the audio information to be processed based on the markings. For example, the audio / video marking unit can mark the audio information according to its chronological order, and the audio / video selection unit can then process the audio information from earliest to latest, prioritizing the earlier audio information.

[0037] In one embodiment, the wireless microphone body 1 further includes a power detection module 14 and an alarm module 15. The power detection module 14 is electrically connected to the first power supply module 13 and is used to monitor the power value of the first power supply module 13 in real time. The signal output terminal of the power detection module 14 is electrically connected to the alarm module 15. The power detection module 14 includes a power detection unit and a control unit. The power detection unit is used to monitor the power value of the first power supply module 13 in real time and send the detected power value to the control unit. When the power value is less than a preset threshold, the control unit controls the alarm module to sound an alarm.

[0038] In this way, the alarm module 15 can be a vibration module. The power detection unit detects the power value of the first power supply module 13 in real time and sends it to the control unit. When the power value of the first power supply module 13 is less than a preset threshold, the control unit controls the vibration module to vibrate, so that the wireless microphone body 1 can feel the vibration and remind the user that the microphone power is low.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
