Description

Technical Field

[0001] This utility model belongs to the field of headphone technology, specifically relating to a combined headphone speaker front shell. Background Technology

[0002] Headphones are devices that convert audio signals into sound, typically used for personal audio playback. Headphones include both wireless and wired headphones, with wireless over-ear headphones being a type of wireless headphone.

[0003] The front shell of a modular headphone speaker is a crucial component of the headphone speaker assembly, typically forming a complete headphone speaker unit together with the rear shell, dust grille, diaphragm, and other parts. Its main function is to create a closed or semi-closed front acoustic chamber, which significantly influences the high-frequency characteristics of the sound. By optimizing the shape, size, and materials of the front acoustic chamber, sound conversion efficiency can be improved, high-frequency noise can be corrected, and sound quality can be enhanced.

[0004] The existing speaker front cover has the following problems during use:

[0005] Currently, the dust filters installed on the front shells of many headphones or speakers are generally attached directly with glue. However, this traditional method has a significant drawback: cleaning becomes extremely inconvenient when dust or dirt accumulates on the dust filters over time. Because the dust filters are tightly bonded to the front shell with glue, users often find it difficult to easily detach them for thorough cleaning. This not only increases the difficulty of cleaning but may also lead to damage to the dust filters or the front shell due to improper handling. Utility Model Content

[0006] (1) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, the purpose of this invention is to provide a modular headphone speaker front shell. This front shell aims to solve the problem of dust filters installed on the front shells of many headphones or speakers, which are generally fixed by direct adhesive bonding. However, this traditional bonding method has a significant drawback: when the dust filter accumulates dust or dirt over time and needs cleaning, it becomes extremely inconvenient. Because the dust filter is tightly bonded to the front shell with adhesive, users often find it difficult to easily separate the dust filter from the front shell for thorough cleaning. This not only increases the difficulty of cleaning but also poses a risk of damage to the dust filter or the front shell due to improper handling.

[0008] (2) Technical solution

[0009] To solve the above-mentioned technical problems, this utility model provides a combined headphone speaker front shell, which includes a front shell housing and a dustproof mesh. The inner wall of the front shell housing is provided with a dustproof mesh, and an installation groove is opened in the interior of the front shell housing near the dustproof mesh. A limiting block passes through the surface of the front shell housing, and a connecting block is connected to the end of the limiting block. A first guide hole is opened on the surface of the connecting block, and a first guide rod passes through the interior of the first guide hole. The first guide rod is connected to the inner wall of the front shell housing, and a first spring strip is connected between the connecting block and the first guide rod.

[0010] When the speaker front shell of this technical solution is used, the limiting block is squeezed and causes the connecting block to move laterally and causes the first guide hole to slide on the surface of the first guide rod. When the connecting block moves laterally, it can compress the first spring strip. When the limiting block moves to the inside of the dustproof net, the dustproof net can be pulled down and removed.

[0011] Preferably, the dustproof net is slidably connected to the front shell through the mounting groove, and the dustproof net can be inserted into the mounting groove, thereby realizing the installation of the dustproof net.

[0012] Furthermore, the limiting block and the front shell are connected in a sliding manner, the connecting block is connected in a sliding manner with the first guide rod through the first guide hole, and the connecting block and the first spring strip are connected in a telescopic structure. When the limiting block is squeezed, the connecting block drives the first guide hole to slide on the surface of the first guide rod. When the connecting block moves laterally, it can compress the first spring strip. When the limiting block moves to the inside of the dustproof net, the dustproof net can be pulled down to remove it.

[0013] Furthermore, the inner wall of the front housing is provided with a mounting base, the side surface of the mounting base is connected with a side lug, the surface of the side lug is provided with a second guide hole, the interior of the second guide hole is through a second guide rod, the second guide rod is connected to the inner wall of the front housing, and a second spring strip is connected between the side lug and the front housing, the second spring strip is sleeved on the surface of the second guide rod.

[0014] Furthermore, the side ear forms a sliding connection with the second guide rod through the second guide hole. When the mounting base is subjected to force, the side ear can drive the surfaces of the second guide hole and the second guide rod to slide, which can limit the movement direction of the mounting base.

[0015] Furthermore, a telescopic structure is formed between the side ear and the second spring strip. When the side ear moves, it can compress the second spring strip, which can be cushioned by the elasticity of the second spring strip.

[0016] (3) Beneficial effects

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

[0018] In this invention, the limiting block is first squeezed. When the limiting block is squeezed, it drives the connecting block to move laterally and causes the first guide hole to slide on the surface of the first guide rod. When the connecting block moves laterally, it can compress the first spring strip. When the limiting block moves to the inside of the dustproof net, the dustproof net can be pulled down and removed, so that the dustproof net can be cleaned. This makes it convenient to clean the dustproof net.

[0019] In this invention, the speaker is mounted on the surface of the mounting base. When the earphone falls, the speaker can slide on the surface of the second guide rod through the mounting base and the side ear. When the side ear moves, it can compress the second spring strip. At this time, the elasticity of the second spring strip can provide cushioning, thereby preventing damage to the speaker when the earphone falls, thus improving the safety of earphone use.

[0027] This specific embodiment is a combined headphone speaker front shell, the structural diagram of which is shown below. Figure 1-6As shown, the front shell of the speaker includes a front shell housing 1 and a dustproof mesh 2. The inner wall of the front shell housing 1 is provided with the dustproof mesh 2. An installation groove 3 is opened inside the front shell housing 1 near the dustproof mesh 2. A limiting block 4 passes through the surface of the front shell housing 1. A connecting block 5 is connected to the end of the limiting block 4. A first guide hole 6 is opened on the surface of the connecting block 5. A first guide rod 7 passes through the first guide hole 6. The first guide rod 7 is connected to the inner wall of the front shell housing 1. A first spring strip 8 is connected between the connecting block 5 and the first guide rod 7.

[0028] Among them, the dustproof net 2 is slidably connected to the front shell 1 through the mounting groove 3, the limiting block 4 is slidably connected to the front shell 1, the connecting block 5 is slidably connected to the first guide rod 7 through the first guide hole 6, and the connecting block 5 and the first spring strip 8 form a telescopic structure.

[0029] In addition, a mounting base 9 is provided on the inner wall of the front housing 1. A side ear 10 is connected to the side surface of the mounting base 9. A second guide hole 11 is opened on the surface of the side ear 10. A second guide rod 12 passes through the interior of the second guide hole 11. The second guide rod 12 is connected to the inner wall of the front housing 1. A second spring strip 13 is connected between the side ear 10 and the front housing 1. The second spring strip 13 is sleeved on the surface of the second guide rod 12. The side ear 10 and the second guide rod 12 are slidably connected through the second guide hole 11. The side ear 10 and the second spring strip 13 form a telescopic structure.

[0030] Working principle: When using the device of this technical solution, when the dustproof net 2 needs to be cleaned, it can squeeze the limiting block 4. When the limiting block 4 is squeezed, it drives the connecting block 5 to move laterally. The lateral movement of the connecting block 5 can drive the first guide hole 6 to slide on the surface of the first guide rod 7. When the connecting block 5 moves laterally, it can compress the first spring strip 8. When the limiting block 4 moves to the inside of the dustproof net 2, the dustproof net 2 can be pulled down and removed, so that the dustproof net 2 can be cleaned. After cleaning, the dustproof net 2 is squeezed on one side of the limiting block 4. When the limiting block 4 is squeezed, it can move into the front shell 1. When the front shell 1 moves, it can drive the connecting block 5 to move laterally and compress the first spring strip 8. Then the dustproof net 2 can be inserted into the installation groove 3. When the dustproof net 2 moves to the upper side of the limiting block 4, the first spring strip 8 is reset by squeezing the limiting block 4 with its own elasticity, so that the dustproof net 2 can be installed.

[0031] When in use, the speaker is installed on the surface of the mounting base 9. When the headphones fall, the speaker can slide on the surface of the second guide rod 12 through the mounting base 9 and the side ear 10. When the side ear 10 moves, it can compress the second spring strip 13. At this time, the elasticity of the second spring strip 13 can buffer the impact, thereby preventing the speaker from being damaged when the headphones fall.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
