[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution:

[0031] A multi-channel PLL phase-locked wireless microphone includes a receiver 1, an antenna 2, and a microphone 3. The receiver 1 has a movable opening 4 on one side, and a movable plate 5 is horizontally slidably disposed on the movable opening 4. The antenna 2 is rotatably disposed on the movable plate 5 and is electrically connected to the receiver 1. The movable plate 5 has a mounting opening 6 on its side, and a spring 7 is disposed in the mounting opening 6. A fixing block 8 is horizontally slidably disposed on the mounting opening 6. The two ends of the spring 7 are fixedly installed to the movable plate 5 and the fixing block 8, respectively. The receiver 1 has a fixing opening 9 located in the movable opening 4. The fixing block 8 and the fixing opening 9 are configured as matching arc surfaces. A baffle 10 is disposed at the opening of the movable opening 4 of the receiver 1.

[0032] In a multi-channel PLL phase-locked wireless microphone, receiver 1 is used to receive and process the audio signal transmitted by microphone 3, antenna 2 is used to enhance receiver 1's ability to receive and transmit wireless signals, and microphone 3 is used to collect sound signals and transmit them wirelessly to receiver 1.

[0033] When antenna 2 needs to be stored and protected, the operator rotates antenna 2 so that it is parallel to the movable plate 5. Then, the operator pushes the movable plate 5 horizontally into the movable opening 4. During the horizontal movement of the movable plate 5, the fixing block 8 is compressed by the squeezing force, causing the spring 7 to enter into the mounting opening 6. When the movable plate 5 is fully inserted into the movable opening 4, the mounting opening 6 is directly opposite the fixing opening 9. The elastic restoring force of the spring 7 will lock the fixing block 8 into the fixing opening 9, thus fixing the movable plate 5 and antenna 2. Finally, the operator will cover the opening of the movable opening 4 with the sliding baffle 10 to complete the storage and protection of antenna 2.

[0034] Conversely, the baffle 10 can be slid open, and the movable plate 5 and antenna 2 can be pulled out from the movable opening 4.

[0035] This multi-channel PLL phase-locked wireless microphone can house the antenna 2 inside the receiver 1, making it easy to carry and significantly reducing the risk of the antenna 2 being damaged by external impacts, making it highly practical.

[0036] Sealing strips are laid along the edges of the baffle 10;

[0037] The edges of the baffle 10 are covered with sealing strips. The sealing strips can fill the tiny gaps between the baffle 10 and the receiver 1, improve the sealing effect of the baffle 10 during protection, prevent dust, moisture and other impurities from entering the movable opening 4 and damaging the antenna 2, further protect the performance of the antenna 2 and extend its service life.

[0038] A storage box 11 is fixedly installed on the side of the receiver 1. A protective cover 12 is threadedly connected to the open end of the storage box 11. The inner diameter of the storage box 11 and the protective cover 12 is adapted to the size of the microphone 3. The inner walls of the storage box 11 and the protective cover 12 are provided with rubber sleeves.

[0039] When microphone 3 is not in use, the storage box 11 fixedly installed on the side of receiver 1 is used to store microphone 3. After microphone 3 is placed in storage box 11, protective cover 12 is connected to the opening end of storage box 11 by thread. Since the inner diameter of storage box 11 and protective cover 12 is compatible with the size of microphone 3, and both storage box 11 and protective cover 12 are equipped with rubber sleeves, the rubber sleeves can play a buffering and protective role, preventing microphone 3 from being damaged by collision during storage, further improving the overall portability of the device, and making it convenient to carry and store.
