[0032] To deepen the understanding of the present invention, the present invention will be further described below in conjunction with implementation examples and accompanying drawings. The present invention can be implemented in the following ways:

[0033] Reference Figure 1-7 A wireless musical instrument receiver includes a housing 1, an antenna 2 and a plug 3 connected to the musical instrument, wherein the antenna 2 and the plug 3 are respectively arranged at both ends of the housing 1.

[0034] The housing 1 includes a detachable front housing 11 and a rear housing 12 , and the front housing 11 and the rear housing 12 are fastened together by a quick-fit assembly to form a cavity 13 for mounting the PCB board 4 and the power module 5 .

[0035] The antenna 2 is mounted on the top of the housing 1 and electrically connected to the PCB 4. The antenna 2 is connected to the PCB 4 via a connecting plate 6. A retaining assembly 120 for mounting the connecting plate 6 is provided within the rear housing 12, near one end of the antenna. The retaining assembly 120 includes a front retaining plate 1201 and a rear retaining plate 1202, respectively disposed on either side of the connecting plate 6. A retaining gap is formed between the front and rear retaining plates 1201, 1202 for inserting the connecting plate 6. During installation, the connecting plate 6 is simply inserted into the retaining gap. Connecting retaining posts 61 extend upward from both ends of the top of the connecting plate 6. The PCB 4 is provided with a connecting notch 42 adapted to accommodate the connecting retaining posts 61. The connecting notch 42 is a U-shaped opening that opens outward. The connecting retaining post 61 is provided with a support step 62 for supporting the PCB 4. When the connection limit post 61 of the connecting plate 6 is engaged with the connection notch 42 of the PCB 4, the bottom plate of the PCB 4 abuts against the support step 62. The limit assembly 120, combined with the downward pressure design of the PCB, allows the connecting plate 6 to be securely mounted within the rear housing 12, preventing the connecting plate 6 from shaking during use and avoiding poor contact between the antenna and the PCB. The connecting plate 6 is provided with an antenna mounting hole 64 for inserting the end of the antenna 2. The antenna mounting hole 64 has a circumferential limit flange 65 extending outward from the end facing the power module, which can improve the connection security between the end of the antenna and the connecting plate 6.

[0036] The power module 5 of this embodiment is a rechargeable lithium battery. The housing 1 is also provided with a charging port 7 for convenient charging. This charging port 7 is a Type-C port. The top of the connecting plate 6 is concave to form a U-shaped mounting portion 63 for mounting the charging port 7.

[0037] The inner side surfaces of the two long sides of the rear housing 12 are provided with several support columns 121 for supporting the bottom of the PCB board 4. In this embodiment, the rear housing 12 has three support columns 121 evenly distributed on the inner side surface of each long side. The distance between the support columns 121 on the two long sides is less than the width of the PCB board 4, allowing the PCB board 4 to be easily placed on the support columns 121. The inner side surface of the front housing 11 is provided with upper pressure blocks 111 for pressing down on the top of the PCB board 4. In this embodiment, the front housing 11 has three upper pressure blocks 111 evenly distributed on the inner side surface of each long side. The distance between the upper pressure blocks 111 and the support columns 121 is exactly the thickness of the PCB board 4, ensuring that the PCB board 4 is firmly fixed when the front and rear housings 11 and 12 are fastened together. The side surfaces of the two long sides of the rear housing 12 are provided with limit columns 122. The edges of the two long sides of the PCB board 4 are provided with limit openings 41 that accommodate the limit columns 122. The limit openings 41 are U-shaped openings that open outward. The top of the retaining post 122 is higher than the support post 121. During installation, the retaining opening 41 of the PCB 4 fits snugly against the retaining post 122, preventing the PCB 4 from moving horizontally, front and back, or left and right. This further enhances the secure connection between the PCB and the antenna. Furthermore, no screws are required for mounting, improving assembly efficiency and reducing production costs.

[0038] The quick-release assembly includes several U-shaped fasteners 112 and several latches 123 that fit within the U-shaped fasteners 112. The U-shaped fasteners 112 are positioned along the long edges of the front housing 11. In this embodiment, four U-shaped fasteners 112 are evenly distributed along each long edge of the front housing 11. The latches 123 are positioned along the long edges of the rear housing 12, with each U-shaped fastener 112 corresponding to each latch 123. In this embodiment, four latches 123 are evenly distributed along each long edge of the rear housing 12. The long edges of the front housing 11 have protruding flanges 113 extending outward for easy installation. The top edges of the long edges of the rear housing 12 have positioning grooves 124 that align with the flanges 113. During assembly, align the front housing 11 with the rear housing 12 and press the two together. The latches 123 on the rear housing 12 automatically snap into the U-shaped fasteners 112, making installation quick and easy.

[0039] The bottom inner side of the rear housing 12 is provided with several sets of curved stopper plates 125 to prevent the power module 5 from rocking side to side. These sets 125 include several parallel curved stopper blocks. The curvature of the blocks is adapted to the power module 5. In this embodiment, each set 125 of curved stopper plates is provided with two to three blocks, preventing the power module 5 from rocking side to side and degrading its performance and service life during long-term use.

[0040] The housing 1 is provided with a plurality of anti-slip recesses 14 at the positions of the four ridges. In this embodiment, five anti-slip recesses 14 are evenly distributed on each ridge, so that the wireless instrument receiver is not likely to slip off when the user holds it.

[0041] The front housing 11 of this embodiment is further provided with a plurality of buttons 8 connected to the PCB board 4 and a plurality of indicator lights 9. The buttons 8 may be switch buttons and reset buttons.

[0042] Assembly method: first insert the connecting plate 6 into the limiting gap between the front limiting plate 1201 and the rear limiting plate 1202, insert the antenna 2 and the plug 3 into and install them from both ends of the shell 1, so that the end of the antenna 2 is inserted into the antenna mounting hole 64 of the connecting plate 6; place the power module 5 in the arc-shaped limiting plate group 125 of the rear shell 12; then place the PCB board 4 on the support column 121, and make the limiting opening 41 of the PCB board 4 just stuck on the limiting column 122. At this time, the connecting notch 42 of the PCB board 4 will also just be engaged with the connecting limiting column 61 of the connecting plate 6; finally, align the front shell 11 with the rear shell 12 and press them to firmly install the front shell 11 on the rear shell 12.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
