DETAILED DESCRIPTION

[0027] Please refer to the drawings 1-6, the present application relates to a quick release earphone with replaceable earphone head, including independent earphone head 1, earphone rod 2, wherein earphone head 1 is provided with earphone function PCB board 15, earphone rod 2 is provided with quick release function PCB board 24, earphone function PCB board 15 is provided with authentication identification code for distinguishing different earphone head 1 type and as authentication identification code signal transmission pin 152, quick release function PCB board 24 is provided with contact 241 in contact with pin 152, quick release function PCB board 24 can identify authentication identification code, earphone rod 2 detects and identifies different types of earphone head 1 through quick release function PCB board 24, the detection IC is arranged on the quick release function PCB board 24, the detection IC is a micro control unit, the earphone head 1 is also provided with a loudspeaker assembly, the pin 152 is provided with four, earphone function PCB board 15 is provided with four pins 152 in contact with contact 241, two of which are used for positive and negative connection of loudspeaker assembly, and the other two pins 152 are used as signal transmission pin of authentication identification code.

[0028] It should be noted that the number of pins 152 of earphone function PCB board 15 and the number of contacts 241 of quick release function PCB board 24 can be increased or reduced according to the needs of detection. The detection IC can be a micro control unit (MCU) for detecting the type of authentication identification code and whether it matches the base. The type of earphone head 1 can be noise reduction earplug, ordinary earplug, 3D stereo surround earplug, game earplug, etc. The loudspeaker assembly can be composed of one or more loudspeaker units, which can be moving coil loudspeaker unit or moving iron loudspeaker unit. Further, the pin 152 is a spring pin with certain elasticity and return function, which facilitates the full contact between the pin 152 and the contact 241.

[0029] Different earphone head 1 is realized by electronic identification and signal processing technology, and the specific working principle is as follows:

[0030] Each ear tip 1 is provided with a unique authentication identification code on the ear function PCB board 15. This identification code can be a string of numbers, letters or binary code, used to uniquely identify the type, function and other related characteristics of the ear tip 1. When the ear tip 1 is connected with the ear stem 2, the pin 152 on the ear function PCB board 15 contacts the contact 241 on the quick release function PCB board 24. In this way, the ear stem 2 can read the authentication identification code on the ear tip 1. The detection IC (micro control unit) is built-in on the quick release function PCB board 24, responsible for reading and identifying the authentication identification code transmitted through the pin 152 and the contact 241. The detection IC can identify the type, function and other related parameters of the ear tip 1 by analyzing this identification code. 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 ear tip 1, to provide the best user experience.

[0031] Inside the earphone, there are some pre-programmed software algorithms for analyzing the authentication identification code and performing corresponding operations according to its content. These algorithms can adjust parameters such as audio processing, call quality, noise cancellation, etc. according to the type and function of the ear tip 1.

[0032] Specifically, the ear tip 1 includes an ear tip shell 11, wherein the ear function PCB board 15, the loudspeaker assembly, the battery, the microphone are all built-in in the ear tip shell 11, and the loudspeaker assembly, the battery, the microphone are all electrically connected with the ear function PCB board 15, wherein one side of the ear tip shell 11 is provided with a quick release through slot 12, the ear stem 2 includes an ear stem shell, and the quick release function PCB board 24 is built-in in the ear stem shell, wherein one end of the ear stem shell passes through the opening of the quick release through slot 12 and moves along the direction of the quick release through slot 12, and the pin 152 of the ear function PCB board 15 is in contact with the contact 241 on the quick release function PCB board 24.

[0033] One side of the ear tip shell 11 is provided with a quick release through slot 12, which is the key part for connecting and separating the ear tip 1 and the ear stem 2. Through the quick release through slot 12, the user can easily assemble or disassemble the ear tip 1 and the ear stem 2. One end of the ear stem shell passes through the opening of the quick release through slot 12 and moves along the direction of the quick release through slot 12. This design allows the user to connect or separate the ear tip 1 and the ear stem 2 by simple action. When the ear tip 1 is connected with the ear stem 2, the pin 152 and the contact 241 will be in close contact, ensuring stable transmission of signals. When it needs to be separated, the user only needs to move the ear stem 2 in the opposite direction, and the ear tip 1 can be easily disassembled.

[0034] Furthermore, it is particularly noteworthy that the track assembly ensures accurate alignment of the earphone head 1 and the earphone stem 2 during connection through specific channels and guide structures, reducing the possibility of improper or incorrect insertion. This design provides higher stability and reliability, effectively avoiding damage caused by loose or frequent insertion and removal. The track assembly is usually designed in a sliding or pushing manner, allowing users to intuitively and simply complete the connection operation. Moreover, since the track assembly achieves connection through sliding or pushing, it can generally withstand greater mechanical stress and impact force. This means that even in frequent use or accidental situations, the connection part can maintain good stability and durability. In addition, the track 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 experience a decline in electrical performance due to looseness or oxidation.

[0035] In particular, the surface of the quick-release slot 12 is provided with a pin protrusion 13, and the edges of the top of the quick-release slot 12 are provided with inwardly protruding clamping blocks 14. The end of the earphone stem 2 shell is provided with a contact slot 211, and the two sides of the end of the earphone stem 2 shell are provided with clamping grooves 212 matched with the clamping blocks 14. The pin 152 of the earphone function PCB 15 passes through the pin protrusion 13, and the surface of the contact slot 211 is provided with a contact hole 213 matched with the contact 241 on the quick-release function PCB 24.

[0036] A pin protrusion 13 is provided on the surface of the quick-release slot 12. This protrusion is designed to secure the pin 152 on the earphone function PCB 15, ensuring that the pin 152 remains in a stable position in the quick-release slot 12 and does not shift during connection or disconnection. This design also helps to improve the reliability of the connection between the pin 152 and the contact 241 on the quick-release function PCB 24.

[0037] Inwardly protruding clamping blocks 14 are provided on both sides of the edges of the top of the quick-release slot 12. These clamping blocks 14 serve as an additional positioning and locking mechanism when the earphone head 1 and the earphone stem 2 are connected. When the earphone stem 2 shell is docked with the earphone head shell 11 through the quick-release slot 12, the clamping blocks 14 interact with the corresponding structures (such as the clamping grooves 212) on the earphone stem 2 shell, ensuring accurate alignment and stable connection between the two.

[0038] The surface of the contact slot 211 is also provided with a contact hole 213 matched with the contact 241 on the quick-release function PCB 24. In this way, when the earphone head 1 and the earphone stem 2 are connected, the contact 241 on the quick-release function PCB 24 can contact the pin 152 on the earphone function PCB 15 through the contact hole 213, achieving the function of transmitting and identifying electrical signals.

[0039] Specifically, the assembly process begins with the end of the earphone stem 2 being inserted into the opening. By pushing forward, the pin protrusion 13 is inserted into the contact slot 211. As the earphone stem 2 moves, the pins 152 that pass through the pin protrusion 13 will sequentially contact the contacts 241 aligned with the contact holes 213, achieving signal connection. The continued movement of the earphone stem 2 causes the clamping grooves 212 on both sides of the end of the earphone stem 2 shell to assemble with the clamping blocks 14, achieving clamping, while the pins 152 are in one-to-one contact with the corresponding contacts 241. Users only need to perform a simple push action to complete the connection between the earphone head 1 and the earphone stem 2. 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 pins 152 and the contacts 241, smooth transmission of audio signals and other related data is achieved, providing users with a high-quality audio experience.

[0040] As a further optimization, in this specific embodiment, the earphone stem 2 shell includes an earphone stem inner shell 21, an earphone stem face shell 22, and an earphone stem decorative shell 23. The clamping grooves 212 and the contact slots 211 are all arranged at the end of the earphone stem inner shell 21. The earphone stem face shell 22 is assembled with the inner wall of the earphone stem inner shell 21 through the clasp blocks 221 on both sides of the bottom surface, and the earphone stem decorative shell 23 covers the surface of the earphone stem face shell 22.

[0041] 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 earphone more fashionable and personalized, meeting the aesthetic needs of different users. The decorative shell also serves to protect the earphone stem 2. It can prevent scratches, fingerprints, and stains from damaging the shell, extending the service life of the earphone. At the same time, the choice of material and process of the decorative shell can also enhance the durability of the earphone. The earphone stem decorative shell 23 can also serve as a carrier for brand identification and product recognition. By printing or engraving brand logos, product names, or slogans on the decorative shell, users' awareness of the brand can be enhanced.

[0042] As a further optimization, a reinforcing rib 214 is provided on both sides of the inner wall of the earphone stem inner shell 21, and the two 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 for preventing damage caused by accidental impact or squeezing. The reinforcing rib 214, through its shape and layout, can provide additional support and fixing points, making the quick-release function PCB board 24 more stable in the earphone stem inner shell 21. This helps to reduce the possibility of loosening or displacement during use.

[0043] As a further optimization, the tail end of the earphone stem inner shell 21 is also provided with a charging terminal 242 hole, and the tail end of the quick-release function PCB board 24 is provided with a charging terminal 242, which extends out of the charging terminal 242 hole. By directly integrating the charging terminal 242 into the quick-release function PCB board 24, the earphone can be directly charged through this terminal without the need for additional cables or connectors. This simplifies the charging process and improves user convenience.

[0044] As a further optimization, a positioning column is provided in the earphone head outer shell 11, and a positioning hole 151 is provided 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.

[0045] The design of the positioning column and the positioning hole 151 allows the earphone function PCB board 15 to be accurately placed in the intended 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 column and the positioning hole 151, the earphone function PCB board 15 can be stably fixed in the earphone head outer shell 11. This fixing method not only enhances the stability of the PCB board, but also helps to reduce the possibility of loosening or falling off during use. At the same time, using the positioning column and the positioning hole 151 for assembly can simplify the assembly steps and improve production efficiency. In addition, this design helps to reduce assembly errors and rework rates, thereby reducing production costs.

[0046] As a further optimization, the quick-release function PCB board 24 is also provided with a wireless module, which is a Bluetooth module or a WIFI module.

[0047] As a further optimization, the earphone stem 2 includes a wireless earphone stem 2 or a wired earphone stem 2, wherein the quick-release function PCB board 24 in the wireless earphone stem 2 is also provided with a wireless module, which is a Bluetooth module or a WIFI module, and the quick-release function PCB board 24 of the wired earphone stem 2 is not provided with the wireless module, but is provided with a corresponding earphone wire 243, which can be a 3.5 earphone interface, a special Lightning connector, a custom TypeC connector, etc. Providing multiple options for earphone design to meet the needs of different users is a good optimization strategy.

[0048] In this scheme, two types of earphone stems 2 are proposed: wireless earphone stems 2 and wired earphone stems 2. Wireless earphone stems 2 integrate wireless modules (such as Bluetooth or WIFI), while wired earphone stems 2 are equipped with corresponding earphone wires 243, which can be 3.5mm earphone interfaces, dedicated Lightning connectors or custom Type-C connectors, etc. This design provides users with more choices, allowing them to choose the appropriate earphone type according to their needs and preferences.

[0049] Advantages of wireless earphone stems 2:

[0050] Wireless earphone stems 2, by integrating Bluetooth or WIFI modules, allow users to enjoy the freedom of wireless music by freeing them from the constraints of wires. Wireless earphones can seamlessly connect to a variety of devices, including smartphones, tablets, computers, etc. Wireless connection may also support advanced functions such as remote control, voice assistants, etc., enhancing user experience.

[0051] Advantages of wired earphone stems 2:

[0052] Wired earphone stems 2 provide more stable audio transmission through physical wires, reducing the possibility of signal interruption.
