DETAILED DESCRIPTION

[0036] See also Figure 1-17As shown, the utility model relates to a wireless headset, comprising an earphone head 1 and an earphone rod 2 which are independent of each other, wherein the earphone head 1 is provided with an earphone function PCB board 15, and the earphone rod 2 is provided with a quick-release function PCB board 24, the earphone function PCB board 15 is provided with an authentication identification code for distinguishing different types of earphone heads 1 and a pin 152 which serves as a signal transmission foot for the authentication identification code, the quick-release function PCB board 24 is provided with a contact point in contact with the pin 152, the quick-release function PCB board 24 can identify the authentication identification code, the earphone rod 2 detects and identifies different types of earphone heads 1 through the quick-release function PCB board 24, the earphone rod 2 is provided with a detection IC, the detection IC is used to identify the authentication identification code, the detection IC is arranged on the quick-release function PCB board 24, the detection IC is a microcontroller unit, a speaker assembly is also provided in the earphone head 1, four pins 152 are provided, and the earphone function PCB board 15 is provided with four pins 152 which contact with the contacts, two of which are used for positive and negative connections of the speaker assembly, and the other two pins 152 serve as signal transmission feet for the authentication identification code.

[0037] It should be noted that the number of pins 152 of the headphone function PCB board 15 and the number of contacts of the quick-release function PCB board 24 can increase or reduce the number of contacts and pins 152 according to the needs of detection. The detection IC can be a microcontroller unit (MCU) for detecting the type of the authentication identification code and whether it matches the base. The types of earphone heads 1 can include noise reduction earplugs, ordinary earplugs, 3D surround earplugs, gaming earplugs, etc. The speaker assembly can be composed of one or more speaker units, and the speaker unit can be a dynamic speaker unit or a moving iron speaker unit. Furthermore, the pin 152 is a spring pin, which has a certain elasticity and return function, so that the pin 152 can fully contact the contact.

[0038] Detection of different earphone tips 1 is achieved through electronic identification and signal processing technology. The specific working principle is as follows:

[0039] Each earphone head 1 is provided with a unique authentication identification code on the earphone function PCB board 15. This identification code can be a string of numbers, letters or binary codes, which is used to uniquely identify the type, function and other related characteristics of the earphone head 1. When the earphone head 1 is connected to the earphone rod 2, the pin 152 on the earphone function PCB board 15 contacts the contact on the quick release function PCB board 24. In this way, the earphone rod 2 can read the authentication identification code on the earphone head 1. The detection IC (micro control unit) is built into the quick release function PCB board 24, which is responsible for reading and identifying the authentication identification code transmitted through the pin 152 and the contact. By parsing this identification code, the detection IC can identify the type, function and other related parameters of the earphone head 1. In addition to the authentication identification code, the pin 152 is also used to transmit audio signals and other related data. In this way, the earphone can adjust the audio output and other functions according to the type and settings of the earphone head 1 to provide the best user experience.

[0040] Inside the headset, there are pre-programmed software algorithms that parse the authentication identification code and take appropriate actions based on its content. These algorithms can adjust audio processing, call quality, noise cancellation and other parameters based on the type and function of the headset head 1.

[0041] Specifically discussed, the earphone head 1 includes an earphone head shell 11 and an earplug connected to one side of the earphone head shell 11, wherein the earphone function PCB board 15, the speaker assembly, the battery, the microphone, and the magnet are all built in the earphone head shell 11, and the speaker assembly, the battery, and the microphone are all electrically connected to the earphone function PCB board 15, wherein a quick-release slot 12 is provided on one side of the earphone head shell 11, and the earphone rod 2 includes an earphone rod shell, and the quick-release function PCB board 24 is built in the earphone rod shell, wherein one end of the earphone rod shell passes through the opening of the quick-release slot 12 and moves along the direction of the quick-release slot 12, and makes the pin 152 of the earphone function PCB board 15 contact with the contact on the quick-release function PCB board 24.

[0042] A quick-release slot 12 is provided on one side of the earphone head shell 11, which is the key part for connecting and separating the earphone head 1 and the earphone rod 2. Through the quick-release slot 12, the user can easily assemble or disassemble the earphone head 1 and the earphone rod 2. One end of the earphone rod 2 shell passes through the opening of the quick-release slot 12 and moves along the direction of the quick-release slot 12. This design allows the user to connect or separate the earphone head 1 and the earphone rod 2 with simple movements. When the earphone head 1 is connected to the earphone rod 2, the pin 152 will be in close contact with the contact to ensure stable signal transmission. When separation is required, the user only needs to move the earphone rod 2 in the opposite direction to easily disassemble the earphone head 1.

[0043] It should be noted that the track-type assembly ensures that the earphone head 1 and the earphone stem 2 are accurately aligned when connected through specific channels and guiding structures, reducing the possibility of improper plugging and unplugging or misplugging. This design provides higher stability and reliability, and effectively avoids damage caused by loose plugging or frequent plugging and unplugging. The track-type assembly is usually designed to slide or push, allowing users to complete the connection operation more intuitively and simply. And because the track-type assembly achieves connection by sliding or pushing, this method can usually withstand greater mechanical stress and impact force. This means that even in frequent use or unexpected situations, the connection part can maintain good stability and durability. In addition, the track-type assembly is usually designed to fit tightly, which helps to ensure that the electrical connection between the earphone head 1 and the earphone stem 2 is more stable and reliable. In contrast, plug-in connections may cause electrical performance degradation due to looseness or oxidation.

[0044] Specifically discussed, a pin protrusion 13 is provided on the surface of the quick-release slot 12, and inwardly protruding locking blocks 14 are provided on both sides of the edge of the top of the quick-release slot 12, wherein a contact slot 211 is provided at the end of the earphone rod 2 shell, and locking slots 212 matched with the locking block 14 are provided on both sides of the end of the earphone rod 2 shell, wherein the pin 152 of the earphone function PCB board 15 passes through the pin protrusion 13, and a contact hole 213 aligned with the contact on the quick-release function PCB board 24 is provided on the surface of the contact slot 211.

[0045] A pin protrusion 13 is provided on the surface of the quick-release slot 12. This protrusion is designed to fix the pin 152 on the headphone function PCB board 15, ensuring that the pin 152 maintains a stable position in the quick-release slot 12 and does not shift during the connection or separation process. This design also helps to improve the connection reliability between the pin 152 and the contact on the quick-release function PCB board 24.

[0046] Inwardly protruding positioning blocks 14 are arranged on both sides of the edge of the top of the quick-release slot 12. The function of these positioning blocks 14 is to provide an additional positioning and locking mechanism when the earphone head 1 is connected to the earphone stem 2. When the earphone stem 2 shell is docked with the earphone head shell 11 through the quick-release slot 12, the positioning blocks 14 will interact with the corresponding structure (such as the positioning groove 212) on the earphone stem 2 shell to ensure accurate alignment and a firm connection between the two.

[0047] The surface of the contact slot 211 is also provided with a contact hole 213 aligned with the contact on the quick release function PCB board 24. In this way, when the earphone head 1 is connected to the earphone rod 2, the contact on the quick release function PCB board 24 can contact the pin 152 on the earphone function PCB board 15 through the contact hole 213, thereby realizing the transmission and recognition function of the electrical signal.

[0048] In the specific assembly process, the end of the earphone rod 2 is first assembled into the opening, and the pin protrusion 13 is pushed forward to enter the contact slot 211. As the earphone rod 2 moves, the pin 152 that passes through the pin protrusion 13 will contact the contacts aligned with the contact hole 213 in turn to achieve signal connection. As the earphone rod 2 continues to move, the positioning grooves 212 on both sides of the end of the earphone rod 2 shell are assembled with the positioning blocks 14 to achieve clamping, and the pin 152 is connected with the corresponding contacts one by one. The user only needs to complete the connection between the earphone head 1 and the earphone rod 2 through a simple forward push. This design not only improves the user experience, but also ensures the stability and reliability of the connection. At the same time, through the corresponding contact connection between the pin 152 and the contact, the smooth transmission of audio signals and other related data is achieved, providing users with a high-quality audio experience.

[0049] As a further optimization scheme, in this specific embodiment, the outer shell of the earphone stem 2 includes an earphone stem inner shell 21, an earphone stem surface shell 22, and an earphone stem decorative shell 23, and the positioning groove 212 and the contact groove 211 are both arranged at the end position of the earphone stem inner shell 21; wherein the earphone stem surface shell 22 is assembled with the inner wall of the earphone stem inner shell 21 through the buckle blocks 221 on both sides of the bottom surface, and the earphone stem decorative shell 23 covers the surface of the earphone stem surface shell 22.

[0050] The primary function of the earphone stem decorative shell 23 is to provide visual appeal. By using different colors, textures, materials or patterns, the decorative shell can make the earphones more fashionable and personalized, meeting the aesthetic needs of different users. The decorative shell also protects the earphone stem 2. It can prevent damage to the shell from scratches, fingerprints and stains, and extend the service life of the earphones. At the same time, the material and process selection of the decorative shell can also enhance the durability of the earphones. The earphone stem decorative shell 23 can also serve as a carrier for brand logo and product identification. By printing or engraving information such as brand logos, product names or slogans on the decorative shell, users' awareness of the brand can be enhanced.

[0051] As a further optimization solution, a reinforcing rib 214 is provided on both sides of the inner wall of the earphone stem inner shell 21, wherein both sides of the quick-release function PCB board 24 are clamped in the earphone stem inner shell 21 through the reinforcing rib 214. The reinforcing rib 214 can effectively increase the local thickness of the earphone stem inner shell 21, thereby enhancing its ability to withstand external forces. This is crucial to prevent damage caused by accidental impact or extrusion. The reinforcing rib 214 can provide additional support and fixing points through its shape and layout, so that the quick-release function PCB board 24 can be more firmly installed in the earphone stem inner shell 21. This helps to reduce the loosening or displacement that may occur during use.

[0052] As a further optimization solution, a charging terminal 242 hole is also provided at the tail end of the earphone stem inner shell 21, and a charging terminal 242 is provided at the tail end of the quick-release function PCB board 24, and the charging terminal 242 extends out of the charging terminal 242 hole. By integrating the charging terminal 242 directly into the quick-release function PCB board 24, the earphones can be charged directly through the terminal without the need for additional cables or connectors. This simplifies the charging process and improves the user's convenience.

[0053] As a further optimization solution, a positioning column is provided in the earphone head shell 11 , and a positioning hole 151 is opened on the earphone function PCB board 15 , wherein the earphone function PCB board 15 is clamped on the positioning column through the positioning hole 151 .

[0054] The design of the positioning post and the positioning hole 151 enables the earphone function PCB board 15 to be accurately placed in the expected position during assembly, avoiding misalignment or deviation. This helps to ensure the correct alignment and connection of the internal components of the earphone. Through the cooperation of the positioning post and the positioning hole 151, the earphone function PCB board 15 can be firmly fixed in the earphone head shell 11. This fixing method not only enhances the stability of the PCB board, but also helps to reduce the loosening or falling off that may occur during use. Using the positioning post and the positioning hole 151 for assembly at the same time can simplify the assembly steps and improve production efficiency. In addition, this design also helps to reduce assembly errors and rework rates, thereby reducing production costs.

[0055] As a further optimization solution, a wireless module is also provided on the quick-release function PCB board 24, and the wireless module is a Bluetooth module or a WIFI module.

[0056] At the same time, in order to charge the earphones discussed above, a charging box is provided in this application, please refer to Figure 1-6 As shown,
