[0001] The utility model belongs to the technical field of earphones, and in particular relates to an earphone with an adjustable circuit board position. Background Art

[0002] Existing earphones on the market are equipped with buttons to adjust the volume or turn the earphone on and off. For example, the extended button of the key assembly of the earphone disclosed in Chinese patent application number 202321046179.5 presses the extended button position on the main circuit board through a protrusion. This prior art does not disclose how the main circuit board is installed in the earphone shell.

[0003] Generally, the main circuit board is fixed in the shell by a fastening structure. For example, the Chinese patent with application number 202220081846.2 is to put the main circuit board on the fixing screw and fasten it through the sleeve and knob to fix the main circuit board. However, this connection method of the main circuit board requires the headphone button structure to have high processing accuracy and assembly accuracy. Otherwise, when the processing and manufacturing or assembly accuracy of the bumps and the expansion buttons in the headphones is not high, or the processing accuracy of the holes corresponding to the sleeves on the main circuit board and the sleeves themselves is not high, the bumps cannot be aligned with the expansion button positions on the main circuit board, and ultimately the case pressing function cannot be realized. Utility Model Content

[0004] The utility model aims to overcome the deficiencies in the prior art and provide an earphone with an adjustable circuit board position.

[0005] To achieve the above purpose, the utility model discloses an earphone with adjustable circuit board position, comprising a shell, an expansion button movably connected to the shell, a transmission member fixed relatively to the expansion button, and a circuit board arranged in the shell, wherein an expansion button position is arranged on one side of the circuit board close to the expansion button, and the position of the expansion button position is opposite to the position of the end of the transmission member away from the expansion button;

[0006] A first positioning groove and a second positioning groove are provided in the housing, the first positioning groove and the second positioning groove are respectively located on both sides of the expansion button, and the circuit board is clamped in the first positioning groove and the second positioning groove and has the ability to move in the length direction thereof;

[0007] It also includes a threaded connector and a locking member arranged on the threaded connector. The threaded connector is threadedly connected to the housing and is pressed and locked by the bottom surface of the locking member.

[0008] Preferably, the first positioning groove and the second positioning groove are respectively located at two ends of the circuit board.

[0009] Further preferably, the tops of the first positioning groove and the second positioning groove are connected, and the two ends of the circuit board are not lower than the corresponding positioning grooves; there are two threaded connectors and two locking members, and the two threaded connectors and locking members are respectively located at the two ends of the circuit board.

[0010] Further preferably, the first positioning groove and the second positioning groove are both provided with a threaded column on one side away from the circuit board, the threaded column is not higher than the corresponding end of the circuit board, and the two threaded connectors are threadedly connected to the corresponding threaded columns.

[0011] Further preferably, notches are formed at the tops of both ends of the circuit board, and the bottom surface of the locking member presses against the bottom surface of the notch.

[0012] Preferably, the threaded connector and the locking member are an integrally formed structure.

[0013] Further preferably, the integrated structure formed by the threaded connector and the locking member is a cap screw.

[0014] Preferably, the threaded connector and the locking member are separate structures.

[0015] Compared with the prior art, the utility model has the following beneficial effects: a first positioning groove and a second positioning groove are provided in the housing, and when assembling the circuit board, the circuit board is clamped in the first positioning groove and the second positioning groove, the threaded connector is threadedly connected to the housing, and the circuit board is pressed and locked by the bottom surface of the locking member, thereby fastening the circuit board to the housing. The above circuit board fastening structure is simple, which is convenient for circuit board assembly and improves assembly efficiency.

[0016] Since the circuit board has the ability to move in the direction of its length, when the transmission member is misaligned with the expansion button position on the circuit board, the threaded connector can be loosened and the circuit board can be moved in the direction of its length until the position of the expansion button position is opposite to the position of the end of the transmission member away from the expansion button, and then the threaded connector can be locked to adjust the position of the circuit board and ensure that the transmission member can act on the expansion button position to realize the corresponding function.

[0017] When the threaded connector moves downward, it provides downward pressure for the locking member to lock the circuit board. The downward pressure is controllable, which can ensure the assembly reliability of the circuit board. In the process of adjusting the circuit board, you only need to loosen the threaded connector without removing it, which is simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In the description of the present invention, it should be understood that the terms "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] In the present invention, unless otherwise clearly defined and specified, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Furthermore, those skilled in the art may combine and associate different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0032] The following is combined with Figure 1-4 The technical solution of the utility model is further explained.

[0033] A headset with a circuit board having four adjustable positions, see Figure 1-2, including a shell 1, an expansion button 2 movably connected to the shell 1, a transmission member 3 fixed relatively to the expansion button 2, and a circuit board 4 arranged in the shell 1, and an expansion button position 5 is provided on the side of the circuit board 4 close to the expansion button 2, and the position of the expansion button position 5 is opposite to the position of the end of the transmission member 3 away from the expansion button 2. Among them, the transmission member 3 is an axis structure, and the expansion button 2 is rotatably connected to the shell 1 and can move along the axial direction of the transmission member 3. Therefore, the expansion button 2 can adjust the volume of the earphone by rotation, and can also be pressed to drive the transmission member 3 to press the expansion button position 5 on the circuit board 4 to realize power on and off. The above structure of the expansion button 2 to realize volume adjustment and power on and off control is a prior art. For details, please refer to the Chinese patent application number 202321046179.5, and its structure will not be repeated here. Figure 1 The earphone of this embodiment is a neck-hanging Bluetooth earphone, which also includes other existing conventional structures, which will not be repeated here.

[0034] See also Figure 1 , Figure 3-Figure 4 The housing 1 is provided with a first positioning groove 11 and a second positioning groove 12, which are respectively located on both sides of the expansion button 2. The circuit board 4 is clamped in the first positioning groove 11 and the second positioning groove 12 and has the ability to move in its length direction. The earphone also includes a threaded connector 6 and a locking member 7 provided on the threaded connector 6. The threaded connector 6 is threadedly connected to the housing 1 and is pressed against and locked by the bottom surface of the locking member 7 to lock the circuit board 4. When assembling the circuit board 4, the circuit board 4 is clamped in the first positioning groove 11 and the second positioning groove 12 to maintain a sideways state (such as Figure 3-Figure 4 ), then the threaded connector 6 is threadedly connected to the housing 1 and the circuit board 4 is pressed and locked by the bottom surface of the locking member 7, so that the circuit board 4 is fastened to the housing 1. The above circuit board 4 fastening structure is simple, which is convenient for assembling the circuit board 4 and improves the assembly efficiency.

[0035] Since the circuit board 4 has the ability to move in the length direction, when the transmission member 3 is misaligned with the expansion button position 5 on the circuit board 4, the threaded connector 6 can be loosened, and the circuit board 4 moves in the length direction until the position of the expansion button position 5 is opposite to the position of the end of the transmission member 3 away from the expansion button 2, and then the threaded connector 6 is locked, and finally the position of the circuit board 4 is adjusted to ensure that the transmission member 3 can act on the expansion button position 5 to achieve the corresponding function. When the threaded connector 6 moves downward, it provides downward pressure to the locking member 7 to lock the circuit board 4. The size of the downward pressure is controllable, which can ensure the assembly reliability of the circuit board 4. In the process of adjusting the circuit board 4, it is only necessary to loosen the threaded connector 6 without removing the threaded connector 6, which is simple to operate.

[0036] Since other devices may be arranged on the circuit board 4, especially near the middle position, if the two positioning grooves are arranged near the position corresponding to the middle position of the circuit board 4, interference may easily occur. Figure 3-Figure 4 The first positioning groove 11 and the second positioning groove 12 are respectively located at two ends of the circuit board 4, so that no interference will occur during the installation of the circuit board 4, which facilitates assembly.

[0037] See also Figure 3-Figure 4 There are two threaded connectors 6 and two locking members 7, and the two threaded connectors 6 and locking members 7 are respectively located at the two ends of the circuit board 4. The tops of the first positioning groove 11 and the second positioning groove 12 are through, and the two ends of the circuit board 4 are not lower than the corresponding positioning grooves, so that the top surface of the circuit board 4 can be exposed to be pressed and locked by the locking member 7. Two threaded connectors 6 and locking members 7 are provided to respectively lock the two ends of the circuit board 4, which improves the assembly stability and reliability of the circuit board 4.

[0038] Preferably, both ends of the circuit board 4 are slightly higher than the corresponding positioning grooves (e.g., 1 mm higher), which ensures that the circuit board 4 can be pressed and locked by the locking member 7, thereby avoiding manufacturing errors in the positioning groove and / or the circuit board 4 that cause the ends of the circuit board 4 to be buried in the positioning groove and unable to be locked, ultimately resulting in problems with poor assembly stability and reliability.

[0039] In this embodiment, a threaded column 13 is provided on the side of the first positioning groove 11 and the second positioning groove 12 in the shell body away from the circuit board 4. The threaded column 13 is not higher than the corresponding end of the circuit board 4 to ensure that the circuit board 4 can be pressed and locked by the locking member 7. The two threaded connectors 6 are threadedly connected to the corresponding threaded column 13 to achieve their threaded connection.

[0040] In this embodiment, notches 41 are formed at the tops of both ends of the circuit board 4, the ends of the circuit board 4 corresponding to the notches 41 are stuck in the positioning grooves, and the bottom surface of the locking member 7 presses against the bottom surface of the notches 41. By providing the notches 41 at the tops of both ends of the circuit board 4, when the threaded connector 6 is connected to the threaded column 13, its top surface will not protrude too much from the top surface of the circuit board 4, and may even be lower than the top surface of the circuit board 4, which is conducive to reducing the height of the internal structure of the housing, thereby reducing the height and size of the housing, making the entire headset more delicate.

[0041] In this embodiment, the threaded connector 6 and the locking member 7 are an integrally formed structure, which is convenient for assembly. Preferably, the integral structure formed by the threaded connector 6 and the locking member 7 is a cap screw. Of course, the threaded connector 6 and the locking member 7 are separate structures, such as the threaded connector 6 is a screw and the locking member 7 is a gasket.

[0042] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
