Description

Technical Field

[0001] This utility model relates to the field of headphone case technology, and in particular to an headphone case and its light-shielding structure. Background Technology

[0002] To facilitate human-computer interaction, consumer electronics products are designed with indicator lights, such as fault indicators, power indicators, function indicators, and ambient lights, to aid in the interaction. Simultaneously, light-transmitting holes are provided on the product's casing, allowing light emitted from the light-emitting unit to pass through them. However, this light emission method requires light-shielding design to prevent light leakage or spillage from the light-emitting unit.

[0003] Existing light shielding typically uses light shielding components with protrusions at the bottom and mounting holes on the PCBA board. The process involves first inserting the protrusions of the light shielding component into the mounting holes on the PCBA board, and then installing the PCBA board into the charging case's inner shell. Because plastic parts are prone to detachment or require additional adhesive to prevent detachment, the assembly process is quite cumbersome. Furthermore, the positioning holes on the PCBA motherboard occupy motherboard space. For example, patent 202222833068.0 discloses a light guide structure for an indicator light and an earphone charging case, which involves mounting plastic parts into the PCBA board, thus occupying motherboard space.
