Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to an improved open-type earphone and an earphone charging box. Background Art

[0002] Open-back headphones are a popular type of headphones. The characteristic of this type of headphones is that they use sponge-like microporous foam plastic to make sound-permeable ear pads. They are small in size and very comfortable to wear, and no longer use heavy sound-stained pads. As a result, there is no sense of isolation from the outside world, and the sound can leak out, and vice versa, the sound of the outside world can also be heard. If the degree of openness of the headphones is very high, the sound from the unit on the other side can be heard, forming a certain mutual feedback, making the listening experience natural.

[0003] Open-back headphones usually have an ear hook and a body. Since the overall height of the ear hook is about 5-6 cm, the overall structure of the open-back headphones is relatively large. When the open-back headphones are placed in the charging box, there may be a problem of poor contact between the charging pins of the open-back headphones and the charging pins of the charging box / or multiple presses are required to align the charging pins, which is inconvenient to use.

[0004] For example, application number: CN202320771862.9 discloses an open-type headset. The headset is adjusted to the wearing position by a dual-axis rotation method. The main unit lacks a mechanism to fix the headset during charging. When this type of open-type headset is placed in the charging box for charging, there may be a problem of poor contact between the charging pins / or multiple presses are required to align the charging pins, which is inconvenient to use.

[0005] Another example is the ear-hook type earphone disclosed in application number: CN202320220250.0, characterized in that it comprises: an earphone shell, the earphone shell comprises a connection end; an earhook component, the earhook component is rotatably connected to the connection end, and the earhook component can rotate between a first rotation position and a second rotation position; the earhook component comprises an earhook and a shell, one end of the earhook is inserted into the shell, and the earhook can move relative to the shell along the axial direction of the shell. An earphone kit, characterized in that it comprises a charging box and an earhook type earphone as described in any one of claims 1 to 9, the charging box comprises an upper cover and a bottom shell that are rotatably connected, a charging compartment is provided in the charging box, and when the earhook component of the earhook type earphone is in the second rotation position, the charging compartment is used to place the earhook type earphone. That is, this earhook type earphone uses the charging compartment for charging, and there is a lack of fixing measures between the two. There may be a problem of poor contact between the charging pin of the open earphone and the charging pin of the charging box / or multiple presses are required to align the charging pin, which is inconvenient to use.
