Referring to fig. 1 to 7 together, a headphone according to an embodiment of the present application will be described.

Referring to fig. 1 to 5, the headphone of the present application includes a base and an earcap support 200, the sound generating unit is disposed on the base, the earcap 400 is fixedly disposed on the earcap support 200, and the earcap support 200 is in clamping fit with the base.

During assembly, the earcap is assembled with the earcap support 200 into a whole, and the sound generating unit is assembled with the seat body into a whole, and then the earcap support 200 is assembled on the seat body.

Referring to fig. 3 and 4, in particular, the seat body includes a mounting portion 100, the mounting portion 100 includes a bottom plate 110 and a flange 120 disposed on the bottom plate 110 and having a ring shape; meanwhile, the earcap holder 200 is annular, and the inner side of the earcap holder 200 is matched with the outer side of the flange 120 on the mounting portion 100, and the earcap holder 200 can be sleeved on the flange 120.

Further, referring to fig. 4, a plurality of grooves a are formed at intervals in a circumferential direction on an outer side wall of the flange 120 of the mounting portion 100; correspondingly, a plurality of elastic parts 210 are formed at intervals along the circumferential direction on the inner side of the earcap support 200, and each elastic part 210 can deform along the tangential direction perpendicular to the ring shape of the inner side of the earcap support 200, so that the earcap supports 200 are correspondingly clamped in the slot positions a one by one.

It will be appreciated that slot a is concerned. The slot a may be formed by a concave portion disposed on the flange 120, a notch disposed on the flange 120, or a space formed between one side of the protrusion 130 disposed on the flange 120 and the bottom plate 110, which is not limited to this.

Further, the position that trench a is located is close to or the bottom plate 110 of butt installation department 100, so, when earmuff support 200 card was located on installation department 100, the clearance between earmuff support 200 and the bottom plate 110 can be as little as possible to avoid earmuff support 200 to appear rocking the condition appearance such as.

It is understood that, with respect to the elastic portion 210, the rigidity of the elastic portion 210 is less than that of the ear muff holder 200. For example, the elastic portion 210 may be an elastic arm having a free end and disposed inside the earcap mount 200, and extending from the inner edge of the earcap mount 200 toward the inner side of the earcap mount 200 and inclined relative to the inner edge of the earcap mount 200; alternatively, the elastic portion 210 may be a semi-annular elastic ring protruding from the inner edge of the earcap holder 200.

In summary, the headset of the present application has at least the following advantages:

on one hand, by arranging the annular flange 120 on the mounting portion 100, a carrier can be provided for the arrangement of the slot position a, and a guiding effect can be achieved for the clamping of the earcap support 200, so that the earcap support 200 and the mounting portion 100 can be conveniently aligned and clamped to be matched.

On the other hand, set up on earmuff support 200 and can follow the elastic component 210 that the inboard annular tangential direction of place of perpendicular to earmuff support 200 warp, set up trench a simultaneously on annular flange 120 lateral wall, so, at the in-process that elastic component 210 removed to trench a along flange 120, thereby elastic component 210 takes place elastic deformation and locates in trench a, and then realizes earmuff support 200 and pedestal block in an organic whole. Because the elastic part 210 can deform along the tangential direction perpendicular to the inner side of the earcap support 200 and in the annular shape, the deformation resistance is small, so that the earcap support 200 can be conveniently clamped with the seat body, and the clamping structure damage caused by overlarge resistance during assembly can be avoided.

Specifically, referring to fig. 3 and 4, in some embodiments of the present application, a plurality of protrusions 130 are circumferentially spaced on an outer side wall of the flange 120, and a slot a is formed between each protrusion 130 and the bottom plate 110.

On the one hand, trench a shaping convenient and fast also, simultaneously, can not occupy the inboard space of flange 120 on installation department 100 yet to can keep the level and smooth of the annular inboard space of flange 120, thereby provide sufficient inner space for spare parts such as assembly sound generating unit.

On the other hand, the slot a is disposed such that the end of the elastic portion 210 clamped in the slot a is located on the same circular track as the inner sidewall of the earcap holder 200 in the natural non-compressed state. In this way, the resistance of the earcap holder 200 to the mounting portion 100 can be reduced, thereby facilitating the assembly.

Specifically, when the earcap holder 200 is fitted over the flange 120 and moves in the depth direction of the flange 120, the elastic part 210 is in a natural state before the elastic part 210 hits the bump 130, so that the resistance of the earcap holder 200 when moving in the depth direction of the flange 120 can be reduced; when the elastic portion 210 contacts the bump 130, the elastic portion 210 is compressed to pass through the bump 130, and after the elastic portion 210 passes through the bump 130, the elastic portion 210 returns to a natural state and is clamped in the slot a formed between the bump 130 and the bottom plate 110.

Further, referring to fig. 3, a side of the protrusion 130 away from the bottom plate 110 is provided with a guide slope 131. The guide inclined surface 131 is arranged, so that when the elastic part 210 touches the guide inclined surface 131, the guide inclined surface 131 can play a role in guiding the movement of the elastic part 210, so that the elastic part 210 can be elastically deformed in the process of moving along the depth direction of the flange 120, and the elastic part 210 can smoothly pass through the bump 130, thereby reducing the passing resistance of the elastic part 210 and avoiding the breakage of the elastic part 210 caused by the excessive resistance.

It will be appreciated that, with reference to fig. 5 and 6, in some embodiments of the present application, each spring 210 is elongated and a hollowed out region 220 is formed between the spring 210 and the inner side wall of the earcap holder 200.

The elastic portion 210 is configured such that the elastic portion 210 is in an elongated elastic bone shape, and compared with the configuration in which the elastic portion 210 is an elastic arm having a free end, when the earcap holder 200 moves along the outer side of the flange 120, the elastic portion 210 does not get stuck, and the like, thereby improving the safety and reliability of the elastic portion 210.

The hollow area 220 is a contraction deformation space when the elastic portion 210 is elastically deformed, and when the elastic portion 210 hits the bump 130, the elastic portion 210 can contract and deform toward the hollow area 220. Thus, the shape of the earcap holder 200 is more regular, and the annular shape of the inner side wall thereof is smoother, thereby facilitating the earcap holder 200 to be sleeved on the outer side of the flange 120.

It will be appreciated that, with reference to fig. 3 and 4, in some embodiments of the present application, the resilient portion 210 is arcuate, with the arcuate top surface of the resilient portion 210 facing the inside of the earcap support 200.

Through setting up elastic part 210 to circular-arc, can strengthen elastic part 210's elasticity to when making elastic part 210 when the card locates trench a, the sufficient elasticity of elastic part 210 makes it can firmly be located in the card of trench a, thereby is favorable to improving the fastness and the stability of assembling between earmuff support 200 and installation department 100.

Meanwhile, correspondingly, referring to fig. 4, a plurality of reinforcing ribs 140 are disposed on a side of the protrusion 130 away from the base plate 110, a top surface of each reinforcing rib 140 is an inclined surface and connects a top surface of the protrusion 130 and an outer side surface of the flange 120, and meanwhile, the reinforcing ribs 140 are disposed in a middle portion of the protrusion 130.

Further, it is understood that the slope of the reinforcing ribs 140 is smaller than the slope of the guide slope 131 of the protrusions 130.

Thus, on one hand, before the elastic part 210 passes through the bump 130, the arc-shaped top surface of the elastic part 210 abuts against the reinforcing rib 140 and is compressed and deformed under the guiding action of the upper inclined surface of the reinforcing rib 140, so that the resistance of the elastic part 210 when passing through the bump 130 can be further reduced; on the other hand, the arrangement of the reinforcing ribs 140 can also improve the stability of the bump 130 on the flange 120, and can avoid the situation that the bump 130 is broken due to excessive force during assembly.

Further, referring to fig. 4, a side of the protrusion 130 away from the outer side of the flange 120 is a circular arc surface.

It can be understood that, in the case that the elastic portion 210 is disposed in an arc shape, the top surface of the protrusion 130 is also disposed in an arc shape, and thus, a gap is formed between two sides of the elastic portion 210 and the protrusion 130, so that the elastic portion 210 can pass through the protrusion 130 conveniently, and the occurrence of jamming and the like can be reduced, so that the assembly between the earmuff bracket 200 and the flange 120 is smoother.

It will be appreciated that in some embodiments of the present application, referring to fig. 6, a side of the elastic part 210 facing the base plate 110 is provided with a slope 211, and specifically, the slope 211 is provided extending from the arc top of the elastic part 210 toward the arc bottom.

Thus, when the earmuff bracket 200 moves on the flange 120 along the depth direction of the flange 120, when the elastic part 210 touches the bump 130, the inclined surface 211 on the elastic part 210 and the guiding inclined surface 131 on the bump 130 are mutually abutted, thereby jointly playing a guiding role, so that the top of the elastic part 210 can be compressed and deformed more smoothly towards the hollowed area 220, the resistance of the elastic part 210 when passing through the bump 130 is reduced, and the assembly between the earmuff bracket 200 and the mounting part 100 is facilitated.

Further, referring to fig. 5 and 6, avoidance positions 230 are respectively disposed on the ear muff supports 200 and on the inner side walls of the ear muff supports 200 located at both sides of each elastic portion 210, the avoidance positions 230 are recessed toward the outer sides of the ear muff supports 200, and the side walls of the avoidance positions 230 are communicated with the top walls of the elastic portions 210.

Further, two avoidance portions 230 located at both sides of the same elastic portion 210 are symmetrically disposed about the elastic portion 210.

Through setting up and dodging position 230 for elastic component 210 both sides are formed with the space of dodging on earcap support 200, promptly, after earcap support 200 cover was located on flange 120, and the interval is gapped between elastic component 210 both sides and the flange 120, and this clearance also is the spaciousness that elastic component 210 can move along the lug 130 left and right sides.

Thus, when the elastic portion 210 passes through the bump 130, the avoiding position 230 enables the elastic portion 210 to slightly rotate and adjust along two sides of the bump 130, so as to avoid the occurrence of the jamming condition when the elastic portion 210 passes through the bump 130 due to the tight fit between the two sides of the elastic portion 210 and the bump 130, and further reduce the resistance of the elastic portion 210 passing through the bump 130.

It can be understood that, referring to fig. 5 and 6, the inner sidewall of the ear muff holder 200 between two adjacent escape positions 230 is located on the same circular track (i.e., the first circular track) as the arc-shaped top of the elastic part 210; moreover, it should be noted that the first circular track is matched with the circular track of the outer side wall of the flange 120, or the first circular track is slightly larger than the circular track of the outer side wall of the flange 120.

Thus, on one hand, when the earcap holder 200 is sleeved on the outer side wall of the flange 120, the gap between the earcap holder 200 and the flange 120 can be reduced, so that the assembling accuracy can be improved; on the other hand, when the elastic portion 210 is clamped in the slot a and the ear muff bracket 200 is assembled with the mounting portion 100, the arc top of the elastic portion 210 can abut against the outer side wall of the flange 120, or only a small gap is formed between the arc top of the elastic portion 210 and the flange 120, so that the ear muff bracket 200 can be prevented from shaking relative to the mounting portion 100.

Further, referring to fig. 7, in any of the above embodiments, a gasket 300 is disposed on the bottom plate 110, and the gasket 300 is made of an elastic material, including but not limited to silicon gel, foam, and the like.

After the earcap mount 200 is assembled with the mounting part 100, the earcap mount 200 presses the gasket 300, and at the same time, the elastic force of the gasket 300 causes the side of the elastic part 210 to be in pressing contact with the side of the protrusion 130 facing the bottom plate 110, thereby reducing the shaking of the earcap mount 200 after being assembled with the mounting part 100. So, through setting up packing ring 300, lower to installation part 100 and/or earmuff support 200's machining precision requirement under the prerequisite of guaranteeing earmuff support 200 assembly stability to greatly make things convenient for earmuff support 200 and installation part 100's manufacturing.

The above description is only a preferred embodiment of the present application and should not be taken as limiting the present application, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
