Description

Technical Field

[0001] The utility model relates to a head-mounted flat-panel earphone, in particular to a head-mounted flat-panel earphone with a composite diaphragm, and belongs to the technical field of composite diaphragms. Background Art

[0002] The composite diaphragm is a headphone diaphragm that combines different materials. It combines the advantages of multiple materials to achieve better sound effects. The composite diaphragm can optimize the high-frequency extension of the sound, present richer details, and reduce low-frequency distortion, providing clearer instrument performance sound.

[0003] After searching, a Chinese patent with publication number CN117201999A discloses an ultra-thin flat headphone, which adopts a new single-sided magnet structure and uses a decorative frame to directly fix the magnet. The speaker unit, the headphone decorative frame and the protective frame are used as an integrated combination structure to make the integrity of the flat speaker stronger. The integrated structure can make the consistency of the sound curve higher and the thickness of the overall headphone thinner and more delicate. A new coil structure is set up, and the density between the coils can be adjusted through the structure of the annular nylon wire, etc., to achieve the function of high-precision tuning based on the size of the ultra-thin flat headphone, and to achieve deep adjustment of the headphone timbre and responsiveness, etc., with more functions and better adjustability. The decorative frame is integrally formed, the structure is more stable, and it is more suitable for high-precision adjustment of the distance between the coils, thereby achieving precise tuning. At the same time, the one-piece molding ensures the beauty of the headphone.

[0004] Although the above scheme can achieve precise tuning, and the one-piece molding ensures the aesthetics of the headphones, the ultra-thin planar headphones in the above patent are difficult to conveniently inspect and repair the composite diaphragm body. After long-term use, the composite diaphragm body will inevitably malfunction, thereby generating noise. For this reason, we provide a composite diaphragm head-mounted planar headphone to solve the above problems. Utility Model Content

[0027] See also Figure 2 One side of the first component protective shell 2 is fixedly connected to one side of the second component protective shell 15, and a composite diaphragm body 1 is fixedly arranged inside the second component protective shell 15. The composite diaphragm body 1 is a prior art and will not be elaborated on herein. A memory rebound sponge 17 is fixedly arranged on the other side of the second component protective shell 15. The memory rebound sponge 17 is a prior art and will not be elaborated on herein.

[0028] See also Figure 1 The two sides of the memory rebound sponge 17 are rotatably connected to the bottom of the adjustment bracket 18. The top of the adjustment bracket 18 is fixedly connected with a control linkage module 19. There are two groups of control linkage modules 19. A heat dissipation support belt 16 and an elastic aluminum strip 20 are fixedly arranged between the two groups of control linkage modules 19. The close fit between the heat dissipation support belt 16 and the elastic aluminum strip 20 can effectively achieve the clamping effect of the flat earphone after wearing, and it is not easy to fall off, and at the same time avoid the phenomenon of excessive clamping.

[0029] See also Figure 2 and Figure 3A guide limiting track 14 is fixedly connected to one side of the second component protective shell 15, and a heat dissipation protection plate 5 is slidably arranged in the groove between the guide limiting track 14 and the second component protective shell 15. The arrangement of the heat dissipation protection plate 5 can effectively form a relatively closed space for the flat-panel headset, thereby increasing the safety performance of the flat-panel headset. An external buckle strip 12 is fixedly arranged on one side of the heat dissipation protection plate 5, and a heat dissipation groove 13 is opened in the middle of the heat dissipation protection plate 5. The arrangement of the external buckle strip 12 and the heat dissipation groove 13 makes it convenient for the user to buckle the heat dissipation protection plate 5, thereby opening the internal space of the flat-panel headset.

[0030] See also Figure 4 The bottom of the inner wall of the first component protective shell 2 is fixedly connected to the bottom of the first tough spring 3, the top of the first tough spring 3 is fixedly connected to the bottom of the first pillar 4, the top of the first pillar 4 contacts the bottom of the heat dissipation protection plate 5, and the tight fit between the first tough spring 3 and the first pillar 4 can effectively prevent the heat dissipation protection plate 5 from excessive movement, so that the groove at the bottom of the heat dissipation protection plate 5 just catches the special-shaped linkage plate 6.

[0031] See also Figure 4 The first component protective shell 2 is internally rotated with a special-shaped linkage plate 6, the top of the special-shaped linkage plate 6 contacts the bottom of the third pillar 9, the top of the third pillar 9 is fixedly connected to the bottom of the spring limiting cap 10, the bottom of the spring limiting cap 10 is fixedly connected to the top of the third tough spring 11, the bottom of the third tough spring 11 is fixedly connected to the top of the first component protective shell 2, the tight fit between the spring limiting cap 10 and the third tough spring 11 can effectively reset the third pillar 9, making it convenient for the third pillar 9 to push the special-shaped linkage plate 6 to move.

[0033] Working principle: When the composite diaphragm body 1 in the planar earphone needs to be inspected and repaired, the spring limiting cap 10 is pressed downward by external force, so that the first component protective shell 2 pushes the special-shaped linkage plate 6 to move, and the second tough spring 8 under the second pillar 7 is compressed, so that the special-shaped linkage plate 6 rotates with the intersection with the first component protective shell 2 as the fulcrum. At this time, the third tough spring 11 is in a compressed state, so that the special-shaped linkage plate 6 gradually moves away from the groove position inside the heat dissipation protection plate 5, and under the action of the elasticity of the first tough spring 3 itself, the first pillar 4 is pushed upward, so that the heat dissipation protection plate 5 is restricted by the guide limiting track 14 and pops up upward. At this time, the external buckle strip 12 is pressed again by external force, and the heat dissipation protection plate 5 can be pulled out as a whole, thereby effectively and conveniently inspecting the composite diaphragm body 1.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model.
