Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0052] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0053] Please refer to Figure 1 As shown, it shows the specific structure of the preferred embodiment of the present utility model, which is a switchable and interconnected wireless microphone, including a microphone lithium battery 11, a microphone lithium battery protection circuit 12, a microphone battery charging circuit 13, and a microphone USB interface 14; the USB interface is electrically connected to the microphone battery charging circuit 13, the microphone lithium battery protection circuit 12, and the microphone lithium battery 11 in sequence.

[0054] It further includes a microphone pickup unit 15, a sound collection circuit 16, a microphone LE Audio TX / RX radio frequency module 17, and a DIP switch 18. The microphone pickup unit 15 is electrically connected to the sound collection circuit 16 and the microphone LE Audio TX / RX radio frequency module 17 in sequence. The microphone LE Audio TX / RX radio frequency module 17 is electrically connected to the DIP switch 18, the microphone USB interface 14, and the microphone battery charging circuit 13 respectively.

[0055] The working principle of the switchable and interconnected wireless microphone is as follows:

[0056] The microphone USB interface 14 is a USB male head provided on the wireless microphone 10, or a USB female socket for connecting a USB data cable to a computer / mobile phone 40. Thus, the wireless microphone 10 as the host can be directly plugged into the computer / mobile phone 40, or connected to the computer / mobile phone 40 through a data cable to achieve the physical connection between the host wireless microphone 10 and the computer / mobile phone 40.

[0057] The wireless microphone 10 is internally provided with a microphone lithium battery 11. During charging, it can be connected to a power source through the microphone USB interface 14, and then supply power to the microphone lithium battery 11 after passing through the microphone battery charging circuit 13 and the microphone lithium battery protection circuit 12. During discharging, the microphone lithium battery 11 outputs current to the microphone LE Audio TX / RX radio frequency module 17 through the microphone lithium battery protection circuit 12.

[0058] The microphone LE Audio TX / RX RF module 17 is a new generation of Bluetooth audio. As the industry transitions from classic Bluetooth audio to low-power audio, the microphone LE Audio TX / RX RF module 17 supports both versions simultaneously and improves sound quality, power consumption, latency, and bandwidth performance. In a preferred embodiment, the FSC-BT631D module of Shenzhen Feiyitong Technology Co., Ltd. can be used. The wireless microphone 10 with transceiver function is used to connect to audio source devices such as smartphones, laptops, or TVs, and then the Auracast broadcast audio is used to transmit the audio content to an unlimited number of other wireless microphones 10.

[0059] The microphone pickup unit 15 is electrically connected to the sound acquisition circuit 16. The sound acquisition circuit 16 filters out the noise, converts it into a digital signal, and inputs it into the microphone LE Audio TX / RX RF module 17.

[0060] By toggling the DIP switch 18 of the wireless microphone 10, the microphone can be switched to the RX mode (also known as the host mode) or the TX mode (also known as the slave mode). When in the RX mode, the corresponding wireless microphone 10 is called the host. When in the RX mode, the corresponding wireless microphone 10 is called the slave.

[0061] When multiple wireless microphones 10 are used together, the wireless microphone 10 in the host mode forms a team with other wireless microphones 10 in the slave mode. The wireless microphone 10 in the slave mode collects external sound signals, processes them through the sound acquisition circuit 16, and then wirelessly transmits them to the host wireless microphone 10 after LE-Audio encoding is completed; the host wireless microphone 10 receives the data transmitted from the slave wireless microphone 10 and transmits it to the computer or mobile phone through the UAC protocol after LE-Audio decoding is completed.

[0062] Embodiment 1

[0069] The wireless microphone 10 in the host mode forms a team with other wireless microphones 10 in the slave mode. The wireless microphones 10 in the slave mode collect external sound signals, which are processed by the sound collection circuit 16 and then wirelessly transmitted to the host wireless microphone 10 after being completed by LE-Audio encoding. The host wireless microphone 10 receives the data transmitted by the slave wireless microphone 10 and transmits it to the computer or mobile phone through the UAC protocol after being completed by LE-Audio decoding.

As Figure 10 As shown, the fourth wireless microphone 104 has a fourth microphone LE Audio TX / RX RF module 174 and a fourth DIP switch 184. That is, by integrating the wireless transmission and reception functions of the wireless microphone 10, the wireless microphone 10 can be switched to a receiving host through the corresponding DIP switch 18, solving the problem that the entire wireless microphone 10 system cannot be used after the receiving host is lost.

[0071] Embodiment 2

[0072] As Figures 11 to 13 As shown, this is Embodiment 2 of the present invention, which uses the above-mentioned multiple switchable and interconnected wireless microphones to form a switchable and interconnected wireless microphone and conference system.

[0075] Different from the first embodiment, a pluggable receiving host 20 is added. As Figure 12As shown in the figure, the pluggable receiving host 20 includes a host USB interface 21 and a host LE Audio RX radio frequency module 22 that are electrically connected. The pluggable receiving host 20 forms a wireless connection with the first wireless microphone 101, the second wireless microphone 102, the third wireless microphone 103, and the fourth wireless microphone 104.

[0076] Embodiment III

[0077] As Figures 14 to 15 shown, it is Embodiment III of the present utility model, which uses the above-mentioned multiple switchable and interconnected wireless microphones to form a switchable and interconnected wireless microphone and conference system.

[0078] A switchable and interconnected wireless microphone and conference system includes multiple switchable and interconnected wireless microphones.

The pluggable receiving host 20 is plugged into the microphone charging bin 30, and the multiple switchable and interconnected wireless microphones can be freely placed into the microphone charging bin 30. Each switchable and interconnected wireless microphone is the same as those in Embodiment I and Embodiment II above.

[0079] In this embodiment, by adding a pluggable receiving host 20 and a microphone charging bin 30, after assembling the pluggable receiving host 20 and the microphone charging bin 30, the microphone charging bin 30 has the transceiver function of the host. Thus, the four slave-mode wireless microphones 10 collect external sound signals, which are processed by the sound collection circuit 16 and then wirelessly transmitted to the microphone charging bin 30 with the pluggable receiving host 20 after being completed by LE-Audio encoding, and then input to the computer / mobile phone 40.

[0080] Embodiment IV

[0081] As Figure 16 and Figure 17 shown, it is Embodiment IV of the present utility model, which uses the above-mentioned multiple switchable and interconnected wireless microphones to form a switchable and interconnected wireless microphone and conference system.

[0083] In summary, the design focus of the present utility model is that a DIP switch 18 is mainly provided on the wireless microphone 10, which can switch the microphone to the RX mode (also known as the host mode) or the TX mode (also known as the slave mode).

[0084] When multiple wireless microphones 10 are used together, the wireless microphone 10 in the host mode teams up with other wireless microphones 10 in the slave mode.

The host wireless microphone 10 receives the data transmitted from the slave wireless microphones 10, and after being completed by LE-Audio decoding, it is transmitted to a computer or a mobile phone through the UAC protocol.

[0085] When multiple wireless microphones 10 are teamed up with a pluggable receiving host, each wireless microphone 10 acts as a slave. Each wireless microphone 10 in the slave mode collects external sound signals, and after being processed by the sound collection circuit 16 and completed by LE-Audio encoding, they are wirelessly transmitted to the pluggable receiving host 20.
