Description

Technical Field

[0001] This utility model relates to the field of headphone shell technology, and in particular to a headphone shell with high-precision positioning. Background Technology

[0002] The earphone shell is an important component of the earphone. It not only provides structural support for the earphone, but also has a significant impact on the connection and stable fixation of the earphone shell.

[0003] In traditional headphone shell designs, the positioning of the shell within the outer shell often relies on relatively simple structures, such as basic slots or simple protrusions. These structures are not easy to achieve high-precision positioning and are prone to producing large errors during assembly. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-precision positioning earphone shell.

[0005] This utility model is achieved using the following technical solution: a high-precision positioning earphone shell, including an outer shell, positioning grooves are provided at the four corners of the inner wall of the outer shell, connecting grooves are provided on both sides of the inner wall of the outer shell, a middle shell is fitted onto the inner wall of the outer shell, a locking hole is provided at the top of the inner wall of the connecting groove, and connecting blocks are fixedly connected to both sides of the middle shell.

[0006] The above technical solution ensures that the middle shell is accurately installed inside the outer shell, and the positioning grooves at the four corners can restrict the position of the middle shell from multiple directions, improving the overall assembly accuracy and providing structural protection for the high-precision positioning function of the headphones.

[0007] As a further improvement to the above solution, a mounting hole is provided at the top of the front end of the connecting block, and a spring is fixedly connected to the inner wall of the mounting hole.

[0008] The above technical solution makes the latch elastic, which facilitates its installation or removal by engaging with the latch hole. During installation, the elasticity of the spring makes it easier for the latch to engage with the latch hole. During disassembly or maintenance, the latch can be easily pulled out of the latch hole, thus improving the convenience of assembly and maintenance.

[0009] As a further improvement to the above solution, a latch is fixedly connected to the front end of the spring, and the latch is adapted to the latch hole.

[0010] The above technical solution provides a simple and reliable connection and fixing method through the cooperation of springs and latches. This elastic fixing method can ensure the stability of the connection, and will not damage the components when disassembly is required. It can also compensate for changes in the size of parts due to manufacturing errors or long-term use to a certain extent.

[0011] As a further improvement to the above solution, positioning blocks are fixedly connected to both sides of the front and rear ends of the middle shell, and the positioning blocks are adapted to the positioning grooves.

[0012] The above technical solution further improves the positioning accuracy of the middle shell within the outer shell, and the positioning restriction from multiple directions such as front, back and sides helps to reduce errors in the assembly process, ensure the stability of the internal structure of the earphone, and thus help to improve the overall performance of the earphone, such as the stability of signal transmission.

[0013] As a further improvement to the above solution, an inner shell is fitted onto the inner wall of the middle shell, and an earphone placement slot is provided on the inner wall of the inner shell.

[0014] Through the above technical solution, the inner shell provides a dedicated space for the earphones, which helps to protect the earphones and prevent them from being damaged by shaking inside the shell or by external impacts. The reasonable socket structure facilitates assembly and disassembly, making it easy to maintain or replace the earphones.

[0015] As a further improvement to the above solution, an earphone cover is rotatably connected to the top of the rear end of the housing via a hinge, and an indicator light is fixedly connected to the middle of the front end of the housing.

[0016] Through the above technical solution, the rotating connection method of the earphone shell cover makes it convenient for users to operate and protects the internal components of the earphone. The indicator light can intuitively show the working status of the earphone to the user, improve the user experience, and allow the user to understand the operation of the earphone in a timely manner. For example, the charging progress can be judged by the indicator light when charging.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention ensures high-precision positioning of the middle shell within the outer shell by setting positioning grooves and positioning blocks. The elastic fixing method of springs and latches makes the connection between the middle shell and the outer shell more stable. When the headphones are subjected to external vibrations or impacts, this connection method can effectively prevent the middle shell from loosening or detaching from the outer shell, ensuring the integrity of the headphone structure and thus extending the service life of the headphones. The presence of the inner shell provides additional protection for the headphones. When the headphones are placed in the headphone placement slot, the inner shell can prevent the headphones from directly colliding with the middle shell or the outer shell, reducing the risk of the headphone shell being scratched or internal parts being damaged.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5 This embodiment of a high-precision positioning earphone shell includes an outer shell 1. Positioning grooves 2 are provided at the four corners of the inner wall of the outer shell 1, and connecting grooves 3 are provided on both sides of the inner wall of the outer shell 1. A middle shell 4 is fitted onto the inner wall of the outer shell 1. A locking hole 5 is provided at the top of the inner wall of the connecting groove 3. Connecting blocks 6 are fixedly connected to both sides of the middle shell 4. The outer shell 1 provides a structural basis for positioning and connection of the middle shell 4 through the positioning grooves 2 at the four corners of the inner wall and the connecting grooves 3 on both sides. The middle shell 4 is initially connected and positioned to the connecting grooves 3 of the outer shell 1 through the connecting blocks 6 on both sides. The locking hole 5 at the top of the inner wall of the connecting groove 3 provides an interface for subsequent fixing.

[0029] The top of the front end of the connecting block 6 is provided with a mounting hole 7. A spring 8 is fixedly connected to the inner wall of the mounting hole 7. The mounting hole 7 at the top of the front end of the connecting block 6 provides a fixed position for the spring 8. The spring 8 is fixed in the mounting hole 7. When the button 9 is subjected to external force, the spring 8 can extend and retract in the mounting hole 7, thereby realizing the elastic movement of the button 9.

[0030] A latch 9 is fixedly connected to the front end of the spring 8. The latch 9 is compatible with the latch hole 5. Since the latch 9 is compatible with the latch hole 5, when the latch 9 is pushed into the latch hole 5 under the action of the spring 8, the connecting block 6 can be fixed in the connecting groove 3, thereby realizing the fixed connection between the middle shell 4 and the outer shell 1.

[0031] Positioning blocks 10 are fixedly connected to both the front and rear sides of the middle shell 4. The positioning blocks 10 are adapted to the positioning grooves 2. The positioning blocks 10 on both the front and rear sides of the middle shell 4 are adapted to the positioning grooves 2 on the inner wall of the outer shell 1. During the assembly process, the positioning blocks 10 slide into the positioning grooves 2, thereby accurately determining the position of the middle shell 4 in the outer shell 1.

[0032] The inner shell 11 is fitted onto the inner wall of the middle shell 4. The inner wall of the inner shell 11 has an earphone placement slot 12. The earphone can be placed in the earphone placement slot 12. The inner shell 11 is fixed inside the middle shell 4 by the fitting relationship with the middle shell 4.

[0033] The top of the rear end of the outer shell 1 is rotatably connected to the earphone shell cover 13 via a hinge. The middle of the front end of the outer shell 1 is fixedly connected to the indicator light 14. The top of the rear end of the outer shell 1 is rotatably connected to the earphone shell cover 13 via a hinge, so that the earphone shell cover 13 can rotate around the hinge, thereby realizing the function of opening and closing the outer shell 1. The indicator light 14 is fixedly connected to the middle of the front end of the outer shell 1. The indicator light 14 is connected to the internal circuit of the earphone and displays the corresponding signal according to the working status of the earphone, such as power on, charging, etc.

[0034] The implementation principle of a high-precision positioning earphone shell in this embodiment is as follows: During assembly, the connecting blocks 6 on both sides of the middle shell 4 are aligned with the connecting grooves 3 on both sides of the inner wall of the outer shell 1. At the same time, the positioning blocks 10 on the front and rear ends of the middle shell 4 are aligned with the positioning grooves 2 at the four corners of the inner wall of the outer shell 1. Since the positioning blocks 10 and the positioning grooves 2 are compatible, the positioning grooves 2 restrict the position of the middle shell 4 from multiple directions, so that the middle shell 4 can be accurately placed inside the outer shell 1. When the connecting block 6 enters the connecting groove 3, the spring 8 in the mounting hole 7 at the top of the front end of the connecting block 6 is in a compressed state. The locking button 9 fixedly connected to its front end is locked into the locking hole 5 at the top of the inner wall of the connecting groove 3 under the elastic force of the spring 8. Because the locking button 9 and the locking hole 5 are compatible, the middle shell 4 and the outer shell 1 are fixedly connected. The inner shell 11 is sleeved on the inner wall of the middle shell 4. The inner shell 11 can... The inner shell 11 is assembled along the inner wall of the middle shell 4. The inner wall of the inner shell 11 has an earphone placement slot 12, in which the earphone can be placed. The inner shell 11 is fixed inside the middle shell 4 by its sleeve relationship with the middle shell 4, providing protection for the earphone. The top of the rear end of the outer shell 1 is rotatably connected to the earphone shell cover 13 by a hinge. This rotatable connection allows the earphone shell cover 13 to rotate around the hinge axis, thereby realizing the function of opening and closing the outer shell 1, which is convenient for users to operate the earphone. An indicator light 14 is fixedly connected to the middle of the front end of the outer shell 1. The indicator light 14 is connected to the internal circuit system of the earphone. During the operation of the earphone, the circuit system will control the indicator light 14 to emit corresponding signals according to different working states, such as lighting different colors of light or flashing, so as to intuitively show the working status of the earphone to the user.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
