[0030] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

Rather, these embodiments are provided to provide a more thorough and complete understanding of this utility model. It should be understood that the drawings and embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0033] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0034] In related technologies, the connection terminal is the connection port between the receiver and the device to be connected. Common connection terminals include USB interfaces and Lightning interfaces. If the user frequently plugs and unplugs the receiver or the weight of the connection port exceeds its design value, the lifespan of the connection port will be significantly shortened, making it prone to breakage. Especially when the connection port is a Lightning interface, one end of the Lightning interface needs to be drilled and soldered on the PCB board, which makes the Lightning interface even more prone to breakage after it is connected to the PCB board.

[0035] Although the connection interface through wire connection can alleviate the above situation, the connection port of the emitter is usually fixed to the PCB board, so the material fatigue problem of traditional connection terminals, especially the connection terminals of the emitter stage, is particularly prominent.

[0036] In view of the problems existing in the above-mentioned related technologies, Embodiment 1 of this application provides a receiver.

[0037] like Figures 2 to 4As shown, the receiver 100 provided in this embodiment of the present invention includes a housing 110, a PCB board 120 and a connection terminal 200. The housing 110 includes a top shell 111 and a bottom shell 112, which are fitted together to form the housing 110. The top shell 111 and the bottom shell 112 are connected by snap-fit ​​or bolts. The PCB board 120 is fixedly disposed inside the housing 110, and the connection terminal 200 is disposed on the housing 110.

[0038] The connection terminal 200 includes a fixed end 210 and a plug-in end 220. One end of the fixed end 210 is fixedly connected to the PCB board 120, and the plug-in end 220 is located at the other end of the fixed end 210 opposite to the PCB board 120. The plug-in end 220 extends from the inside of the housing 110, and the exposed portion of the plug-in end 220 is used to connect to a mobile terminal device. When the receiver 100 is connected to a mobile terminal device such as a mobile phone or camera, it can receive audio signals after connecting the receiver 100 to the mobile terminal device through the connection terminal 200.

[0039] like Figure 4 and Figure 5 As shown, a reinforcing member 300 is provided on the fixed end 210 of this application. The reinforcing member 300 covers the outside of the fixed end 210. The fixed end 210 covered with the reinforcing member 300 can effectively improve its toughness and increase the overall connection strength between the connecting terminal 200 and the PCB board 120, so that the connecting terminal 200 is not easy to break when subjected to external force and repeated insertion and removal, thereby increasing the service life and safety of the receiver 100.

[0040] The fixed end 210 is provided with at least one pin 310. The pin 310 is integrally connected to the reinforcing member 300, and the fixed end 210 is fixedly connected to the PCB board 120 through the pin 310. The reinforcing member 300 is provided with pin 310 on one side or both sides, thereby further increasing the connection strength between the connecting terminal 200 and the PCB board 120 and improving the overall assembly strength of the connecting terminal 200 and the reinforcing member 300.

[0041] In this embodiment, pins 310 are provided on both sides of the reinforcing member 300. The pins 310 are fixed to the PCB board 120 by welding, which makes the connection more secure and easier to process and assemble.

[0042] In other embodiments, pin 310 can also be fixed to PCB board 120 in other ways, such as plugging or snapping. The above connection method can also increase the connection strength between connection terminal 200 and PCB board 120.

[0043] Specifically, the reinforcing member 300 includes tinplate wrapped around the fixed end 210. The lead 310 is integrally formed by stamping and bending through the side wall of the reinforcing member 300. The lead 310 is sheet-shaped and attached to the PCB board 120. In this embodiment, the tinplate uses a stampable thin steel plate as the base, and a protective film such as tin is plated on its surface, which makes the reinforcing member 300 lightweight, high-strength, and highly adaptable to environmental temperature.

[0044] This embodiment increases the load-bearing capacity of the connecting terminal 200 by wrapping the fixed end 210 with tinplate, making the connecting terminal 200 less prone to breakage when subjected to external stress impact or repeated insertion and removal, thereby improving the service life and safety of the receiver 100.

[0045] like Figure 5 As shown, a mounting slot 121 is provided on the PCB board 120, and the fixed end 210 is disposed in the mounting slot 121, thereby making more reasonable use of space and compressing the size of the receiver 100, making the receiver 100 more compact overall. Among them, the pin 310 and the edge of the mounting slot 121 are fixed by welding, thereby improving the assembly stability of the reinforcing member 300.

[0046] The connecting terminal 200 is connected to the PCB board 120 via a flexible circuit board and is electrically connected to the corresponding contacts on the PCB board 120 via SMT mounting. As electronic products, such as the receiver 100 in this application, increasingly pursue miniaturization, and existing through-hole components are difficult to further reduce in size, this application employs SMT mounting technology, i.e., surface mount technology, to further improve assembly density, compress the size of the receiver 100, and reduce its weight. Simultaneously, it has good high-frequency characteristics, can reduce electromagnetic and radio frequency interference, and is easy to process, improving production efficiency.

[0047] A preset distance of 10mm to 20mm is provided between the connecting terminal 200 and the bottom of the mounting groove 121. This preset distance can improve the stability of signal transmission and can also be used for soldering the connecting pins of the connecting terminal 200 to the corresponding contacts on the PCB board 120.

[0048] like Figure 6 and Figure 7 As shown, the housing 110 is provided with an assembly hole 410. One end of the connection terminal 200 is fixedly connected to the PCB board 120, and the other end of the connection terminal 200 passes through the assembly hole 410, with the exposed part used to connect to the mobile terminal device.

[0049] Specifically, the outer casing 110 is provided with an outwardly protruding mounting platform 400, and the inner side of the mounting platform 400 is recessed to form a mounting groove 420, which is adapted to the fixed end 210. Among them, the mounting hole 410 is opened in the middle of the mounting platform 400, and the edge of the mounting hole 410 is provided with a flange 430. The inner end face of the flange 430 abuts against the outer end face of the fixed end 210, so that the fixed end 210 is limited and fixed along the axial position of the mounting hole 410.

[0050] In a further embodiment, when the fixed end 210 is assembled in the assembly groove 420, the outer side of the fixed end 210 fits against the inner side of the assembly groove 420, further increasing the assembly stability of the connecting terminal 200 and avoiding the risk of the connecting terminal 200 breaking due to shaking caused by external impact.

[0051] Combination Figure 2 and Figure 6 As shown, the receiver 100 also includes a charging interface 130 and a control button 140, which are electrically connected to the PCB board 120.

[0052] The control button 140 is used to control the working state of the receiver 100. For example, pressing and holding the control button 140 is used to switch the receiver 100 to the power on / off state, and pressing the control button 140 briefly is used to switch the receiver 100 to the wireless transmission state.

[0053] The charging interface 130 and the connection terminal 200 are electrically connected through the PCB board 120. When the charging interface 130 is connected to an external charging device, it can charge the receiver 100. When the connection terminal 200 is connected to a mobile terminal device, such as a mobile phone or tablet, the charging interface 130 can also be used as an adapter to charge the mobile terminal device while charging the receiver 100.

[0054] Specifically, the outer casing 110 is provided with a charging socket 150, which is adapted to the charging interface 130. An external charging device passes through the charging socket 150 and connects to the charging interface 130.

[0055] In this embodiment, the charging port 150 is a Type-C port.

[0056] It should be noted that the structural design of the connection terminal 200 in this application can be applied to the receiver 100 and can also be used for connection of other ports. This application is only an example and not a limitation.

[0057] In summary, the receiver 100 of this application effectively enhances the toughness and connection strength of the connection terminal 200 by covering the fixed end 210 of the connection terminal 200 with a reinforcing member 300 and setting pins 310 on the reinforcing member 300, which is fixedly connected to the PCB board 120 through the pins 310. When the connection terminal 200 is subjected to a large current or external mechanical stress, it is not easy to break and maintains good conductivity, ensuring that the receiver 100 can work stably under various complex usage conditions, thereby improving the overall performance and safety of the product.

[0058] Example 2

[0059] In view of the problems existing in the above-mentioned related technologies, Embodiment 2 of this application provides a receiver.

[0060] like Figures 8 to 10 As shown, the receiver 100 includes a housing 110, a PCB board 120, and a connection terminal 200. The PCB board 120 is fixedly disposed inside the housing 110, and the connection terminal 200 is disposed on the housing 110. The connection terminal 200 includes a fixed end 210 and a plug-in end 220. One end of the fixed end 210 is fixedly connected to the PCB board 120, and the plug-in end 220 is located at the other end of the fixed end 210 opposite to the PCB board 120. The plug-in end 220 extends out from the inside of the housing 110, and its exposed portion is used to connect to an external mobile terminal device.

[0061] The similarities between Embodiment 2 and Embodiment 1 will not be repeated here. The difference between Embodiment 2 and Embodiment 1 is that a reinforcing member 300 connected to the PCB board 120 is provided on the fixed end 210. The reinforcing member 300 covers the outside of the fixed end 210 and includes an extension portion 320 extending into the inside of the PCB board 120. The extension portion 320 is fixedly connected to the PCB board 120 through a connector 330.

[0062] The end of the reinforcing member 300 extends into the inside of the PCB board 120 to form an extension 320. The extension 320 is integrally formed with the reinforcing member 300. The reinforcing member 300 is a tinplate wrapped around the outside of the fixed end 210.

[0063] The extension 320 is provided with a connection hole 321, and the inner side of the housing 110 is provided with a positioning hole 160. The positioning hole 160 is provided in correspondence with the connection hole 321. After the connector 330 passes through the connection hole 321, it is fixedly connected to the positioning hole 160, which further enhances the tightness and stability of the reinforcing member 300, making the connecting terminal 200 less prone to breakage and increasing the load-bearing capacity of the connecting terminal 200.

[0064] A shock absorber 331 is provided on the outer side of the connector 330. The shock absorber 331 is sleeved on the outer side of the connector 330 and is located between the extension and the housing 110 to avoid a hard connection between the connector terminal 200 and the housing 110, thus ensuring the sound reception quality of the receiver 100. The shock absorber 331 is a rubber sleeve.

[0065] Specifically, the extension 320 and the connecting hole 321 are provided on the side facing the top shell 111. A positioning post 170 is provided on the inner side of the top shell 111. The positioning hole 160 is opened in the middle of the positioning post 170 and is correspondingly provided to the connecting hole 321.

[0066] In this embodiment, the connector 330 is a bolt, the positioning hole 160 is a screw hole, and the connector 330 passes through the connecting hole 321 and is threadedly connected and fixed to the positioning hole 160.

[0067] In other embodiments, the connector 330 can also be a pin, and the positioning hole 160 can also be a socket. After the connector 330 passes through the connecting hole 321, it is snapped and fixed with the positioning hole 160 or connected and fixed with an interference fit.

[0068] In summary, the receiver 100 of this embodiment effectively enhances the toughness and connection strength of the connection terminal 200 by covering the fixed end 210 of the connection terminal 200 with a reinforcing member 300, and the reinforcing member 300 extends into the PCB board 120 to form an extension portion 320, and is connected to the PCB board 120 through a connector 330. When the connection terminal 200 is subjected to a large current or external mechanical stress, it is not easy to break and maintains good conductivity, ensuring that the receiver 100 can work stably under various complex usage conditions, thereby improving the overall performance and safety of the product.

[0069] This utility model also provides a microphone, such as Figure 1 As shown, the device includes the aforementioned receiver 100, transmitter 600, and charging case 500. Transmitter 600 and receiver 100 are connected wirelessly, such as via Bluetooth. The charging case 500 is compatible with both transmitter 600 and receiver 100. Once paired successfully, the device is ready for use. The charging case 500 includes a body 510 and a cover 520. Both receiver 100 and transmitter 600 are movably mounted within the body 510. Receiver 100 can connect to devices such as mobile phones, tablets, or cameras for audio recording.

[0070] The microphone 10 in this embodiment includes two transmitters 600, and the receiver 100 is adapted to the two transmitters 600 in a one-to-two configuration.

[0071] The charging case 500 has a receiving cavity 530 inside its body 510. The receiving cavity 530 is used to assemble the receiver 100, which is placed inside the receiving cavity 530 after use. The receiving cavity 530 and the receiver 100 are magnetically connected. That is, corresponding magnets are provided inside the outer shell 110 of the receiver 100 and inside the body 510, so that when the receiver 100 is stored in the receiving cavity 530, the two are magnetically connected, preventing the receiver 100 from falling out of the receiving cavity 530 when the cover 520 is accidentally opened.

[0072] In other embodiments, the charging case 500 or the receiver 100 is provided with interactive terminals such as a display screen, buttons and knobs for displaying real-time information and real-time operation.
