Example 1

An embodiment of the present utility model provides a wireless communication system, which can be suitable for various special communication scenarios, such as a swimming training scenario involving underwater communication, as shown in fig. 1, and mainly includes at least one wireless microphone 11, at least one host 21, and at least one bone conduction earphone 31, wherein:

the wireless microphone 11, as shown in fig. 2, includes a first voice acquisition module 111, a first communication module 112 and a second communication module 113, where the first voice acquisition module 111 is connected with the first communication module 112 and the second communication module 113.

In the wireless communication system provided in the present embodiment, the wireless microphone 11 serves as only one of "speaking", that is, as a "speaking" party. The wireless microphone 11 is configured with a voice acquisition module 111 for recording voice information, and generally includes a built-in microphone and a built-in chip, the built-in microphone can acquire voice information of a user, the built-in chip (such as an audio processor) is matched to complete generation of voice signals acquired by voice information, finally, the first communication module 112 or the second communication module 113 sends out voice signals, and specifically, in this embodiment, the difference between the first communication module 112 and the second communication module 113 in the wireless microphone 11 is that the voice signals can be sent out in different forms, such as different frequency bands, different wireless radio frequency technologies (such as bluetooth and RF radio frequency), for example, the first communication module 112 sends voice signals in a first frequency band (for convenience of distinguishing the first signals), and the second communication module 113 sends voice signals in a second frequency band (for convenience of distinguishing the second signals). In actual operation, the wireless microphone 11 can switch between the first communication module 112 and the second communication module 113 to realize switching between different communication modes.

As shown in fig. 3, the host 21 includes a second voice acquisition module 211 and a third communication module 212, where the third communication module 212 is further configured to be wirelessly connected to the first communication module 112.

In the wireless communication system provided in this embodiment, the host 21 can also be used as a party for "speaking", so that it is also provided with a second voice acquisition module 211 for acquiring voice information, where a built-in microphone and a built-in chip are also provided for completing the generation of the acquired voice signal of the voice information, and the voice signal generated by the second voice acquisition module 211 can be sent out in the form of a wireless signal through the third communication module 212 (for convenience of distinguishing into a third signal). Specifically, in the present embodiment, the host 21 can be used as a bridging party in addition to the "speaking" party: the third communication module 212 can establish a wireless communication connection with the first communication module 112, receive the wireless signal (i.e. the first signal) sent by the first communication module 112, and convert the wireless signal into a third signal to send out, thereby realizing the extension of the communication distance of the wireless microphone 11.

The bone conduction earphone 31 is a receiving party in the wireless communication system, namely, is used as a "listening" party, and the reason why the bone conduction technology is adopted instead of the conventional speaker technology in this embodiment is that the conventional speaker technology needs a very excellent waterproof means in special scenes such as underwater, and the like, so that the cost is very high and the bone conduction earphone 31 is easily interfered by noise, while the waterproof technology of the bone conduction earphone 31 is very mature and has a good listening effect underwater. Specifically, in this embodiment, a wireless receiving module is disposed in the bone conduction headset 31 to receive wireless signals from the wireless microphone 11 and the host 21, that is, wireless signals sent by the first communication module 112, the second communication module 113 and the third communication module 212, analyze the received wireless signals and play voice information, where the wireless signals sent by the third communication module 212 are wireless signals generated according to the voice information collected by the second voice collection module 211 or first signals sent by the forwarded first communication module 112.
