Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 A Bluetooth headset with easily replaceable ear tips includes a headset frame 1. Both ends of the headset frame 1 are provided with mounting plates 2. Two symmetrically arranged snap-fit ​​grooves 3 are formed on the mounting plates 2. A locking button 4 is slidably connected to the outer end of the mounting plate 2. Two first locking strips 5 are symmetrically fixed on the locking button 4. One end of each first locking strip 5 passes through the mounting plate 2 and is located within the snap-fit ​​groove 3. The first locking strip 5 is slidably connected to the mounting plate 2. A first spring 6 is fixed to the inner end of the locking button 4, and the other end of the first spring 6 is fixed to the mounting plate 2. A sound outlet 7 is provided at the center of the inner side of the mounting plate 2. An annular rigid plate 8 is provided on the inner side of the mounting plate 2, contacting the inner side of the mounting plate 2. The annular rigid plate 8 is located away from the mounting plate. Two protrusions 9 are symmetrically arranged on one side of the end plate 2. A pressing groove 10 is provided on the annular hard plate 8 at the position of the protrusion 9. A second locking strip 11 is slidably connected in the pressing groove 10. The two second locking strips 11 are respectively located in two locking grooves 3 and are locked with the first locking strip 5. A pressing block 12 is fixed on the second locking strip 11 at the position of the protrusion 9. The pressing block 12 passes through the protrusion 9 and is located on the outside. A second spring 13 is fixed on the second locking strip 11. The other end of the second spring 13 is fixed on the pressing groove 10. An ear cover body 14 is fixed on the end of the annular hard plate 8 away from the mounting end plate 2. A placement groove 15 is provided on the ear cover body 14 corresponding to the position of the protrusion 9. The protrusion 9 and the pressing block 12 are located in the placement groove 15.

[0022] When using this device, if the earcup needs to be removed, the earcup body 14 is made of a relatively soft material. Pressing the upper and lower sides of the earcup with your fingers squeezes the pressing blocks 12 on both sides. The pressing blocks 12 drive the second locking strip 11 to move along the pressing groove 10 towards the center. At this time, the second spring 13 is compressed, and the second locking strip 11 disengages from the first locking strip 5, allowing the earcup body 14 to detach from the annular hard plate 8 and the mounting end plate 2, thus achieving disassembly. During installation, under the action of the second spring 13, the second locking strip 11 is pushed outwards by the second spring 13. This brings the earcup body 14 and the annular hard plate 8 closer to and closer to the mounting end plate 2. At this time, the second locking strip 11 inserts into the locking groove 3 and contacts the first locking strip 5, resulting in compression. Under the action of force, the second spring... When 13 is compressed, the second locking strip 11 moves. At this time, the second locking strip 11 cannot engage with the first locking strip 5. Press the ear cup body 14 and the locking button 4 by hand to bring them closer together. At this time, the first spring 6 is compressed, and the locking button 4 drives the first locking strip 5 to move inward, causing the first locking strip 5 and the second locking strip 11 to misalign. Under the action of the second spring 13, the front end of the second locking strip 11 fits against the first locking strip 5, achieving engagement, and the locking button 4 and the ear cup body 14 are released. At this time, the first spring 6 releases potential energy, pushing the locking button 4 and the first locking strip 5 to move outward. Because the first locking strip 5 and the second locking strip 11 are engaged, the second locking strip 11, the annular hard plate 8 and the ear cup body 14 are driven to further fit against the installation end plate 2, completing the installation.

[0023] In actual use, it was found that the head circumference of the users of the headphones varies. In order to accommodate different users, the headphone frame 1 is provided with a telescopic function in this embodiment.

[0024] In actual use, it was found that the movement of the second locking strip 11 along the pressing groove 10 may be unstable, which may result in the inability to disengage the second locking strip 11 from the first locking strip 5. In order to solve the above problem, in this embodiment, a limiting post 16 is fixed in the pressing groove 10, and the limiting post 16 passes through the second locking strip 11 and is slidably connected to it.

[0025] In actual use, it was found that the locking button 4 may slip when pressed. In order to solve the above problem, in this embodiment, the outer wall of the locking button 4 is provided with protective texture.

[0026] In actual use, it was found that when the user wears the headphones, the headphone stand 1 will bump against the user's head. In order to avoid the above problem, in this embodiment, the headphone stand 1 is fixed with a protective pad 17.
