Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a headphone. Background Art

[0002] Headphones consist of a headband and two speakers, one mounted on each end of the headband. The speakers typically consist of a base, a cover, and a sound-generating component. The sound-generating component is fixedly mounted inside the base, while the cover is removably mounted on the base to cover the sound-generating component. Existing connections between the cover and base typically use snaps or screws.

[0003] If a snap-on connection is used, the clamping fit is achieved through the clamping claws and the clamping holes, but the clamping claws are prone to breakage during the disassembly and assembly process.

[0004] When screws are used for connection, studs are typically formed inside the bottom housing, and countersunk holes corresponding to the studs are provided in the cover. Screws pass through the countersunk holes and then engage with the studs, thus achieving a removable connection between the cover and the bottom housing. However, since the cover is located on the inner side of the speaker and needs to fit against the ear, the countersunk holes can cause discomfort. To address this issue, a mounting plate is typically added to the outer side of the cover, which is typically removably connected to the cover via a snap-fit ​​mechanism.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] This utility model discloses a specific embodiment of a headset, please see Figures 1 to 4 The earphones include two speakers, a headband 4, two T-shaped brackets 5, and two C-shaped brackets 6. A first hinge hole is provided at the end of the headband 4 facing the T-shaped bracket 5, and the longitudinal section of the T-shaped bracket 5 is inserted into the first hinge hole. It should be noted that the longitudinal section of the T-shaped bracket 5 and the headband 4 are hinged, and a pair of mounting ears 61 extend from the middle of the C-shaped bracket 6 toward the T-shaped bracket 5. The two transverse sections of the T-shaped bracket 5 are inserted into the corresponding mounting ears 61. Similarly, the transverse section of the T-shaped bracket 5 and the mounting ears 61 are hinged, and the two ends of the C-shaped bracket 6 are respectively hinged to the bottom shell 1 of the speaker. In this way, the bottom shell 1 of the speaker can be adjusted in multiple directions, thereby improving the applicability of the earphones.

[0022] As an improvement, the speaker includes a bottom shell 1, a cover plate 2 and a decorative plate 3, and the cover plate 2 is fixed to the bottom shell 1 by screws. Figure 3 A boss 21 extends upward from the middle of the cover plate 2. The end surface of the boss 21 features a hollow structure. Extending outward from the outer peripheral side of the boss 21 are multiple latching protrusions 22 spaced circumferentially along the boss 21. A groove 23 is formed between each latching protrusion 22 and the cover plate 2. The entrance of the groove 23 communicates with the end surface of the latching protrusion 22. The length of the groove 23 can extend through the entire latching protrusion 22, or, as in this embodiment, the length of the groove 23 is shorter than the length of the latching protrusion 22. This allows a portion of the latching protrusion 22 to connect to the cover plate 2, limiting the rotation of the decorative panel 3. Furthermore, a protrusion 24 is provided at the bottom of each groove 23.

[0023] Please first Figure 4 The decorative panel 3 is arranged in a circular ring shape, and a plurality of holding portions arranged at intervals along the circumference of the decorative panel 3 extend inward from the inner side surface of the decorative panel 3. Each holding portion extends an elastic arm 32 along the circumference of the decorative panel 3. A gap is left between the elastic arm 32 and the inner ring surface of the decorative panel 3. The gap is mainly used to give the elastic arm 32 a certain deformation space, which can reduce the risk of the elastic arm 32 breaking. A limiting groove 33 is formed on the end face of each elastic arm 32 facing the groove 23.

[0024] During assembly, the holding portion of the decorative panel 3 is staggered with the locking protrusion 22 of the cover panel 2, and then the decorative panel 3 is placed on the outer peripheral side of the boss 21 of the cover panel 2. After it is in place, the decorative panel 3 is rotated so that the holding portion of the decorative panel 3 is placed in the corresponding groove 23, until the protrusion 24 in the groove 23 is placed in the limiting groove 33 of the elastic arm 32, and the assembly of the decorative panel 3 is completed. Compared with the existing technology, the decorative panel 3 is installed by rotation, and the limiting is achieved by the cooperation between the groove 23 and the holding portion, and the positioning is achieved by the cooperation between the elastic arm 32 and the protrusion 24. The overall structure is simple and compact, making the disassembly and assembly of the decorative panel 3 more convenient and quick, replacing the previous hook-type snap-on method, and solving the problem of short service life. The decorative panel 3 with this structure can be frequently disassembled and assembled, and different styles of decorative panels 3 can be replaced to change the beauty of the headphones and enhance the consumer experience.

[0025] As a preferred solution, the cross-sectional shape of the locking protrusion 22 is semicircular, and the cross-sectional shape of the limiting groove 33 is semicircular. The semicircular structure can improve the fluidity of the disassembly and assembly of the decorative panel 3.

[0026] In addition, a convex ring extends upward from the outer peripheral side surface of the decorative plate 3 , and the convex ring can enhance the structural strength of the decorative plate 3 .

[0027] Finally, it should be noted that the headset disclosed in the embodiment of the present invention is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, rather than to limit it.
