Description

TECHNICAL FIELD

This application pertains to the technical field of headphones, in particular to an earmuff and head-mounted headphones.

BACKGROUND

With the development of science and technology, head-mounted headphones are increasingly widely used, and users' requirements for head-mounted headphones are also increasing. FIG. 1 shows a cross-sectional view of a conventional earmuff. As shown in FIG. 1, the conventional earmuff comprises earmuff sponge 2′ and earmuff leather 3′. When external noise enters the interior of the earmuff, it only needs to pass through the earmuff leather 3′ and the earmuff sponge 2′. Then, it passes through the earmuff sponge 2′, and then passes through the earmuff leather 3′, and finally enters the interior of the earmuff and thus enters the human ear. Since external noise only passes through two types of conducting media, i.e., the earmuff leather 3′ and the earmuff sponge 2′, it cannot effectively reduce the noise, and the passive noise reduction ability of headphones is poor. In addition, other objects, desirable features and characteristics will become apparent from the subsequent summary and detailed description, and the appended claims, taken in conjunction with the accompanying drawings and this background.

First Embodiment

FIG. 2 shows a cross-sectional view of an earmuff according to an embodiment of the present disclosure. As shown in FIG. 2, the earmuff of the present disclosure comprises an earmuff airbag 1, earmuff sponge 2, and earmuff leather 3. The earmuff sponge 2 is wrapped on the outer surface of the earmuff airbag 1. The earmuff leather 3 is wrapped on the outer surface of the earmuff sponge 2. The earmuff airbag 1 comprises at least one hollow enclosed airbag and has a certain support force. Moreover, the earmuff airbag 1 is made of a soft rubber material, thereby ensuring the overall softness of the earmuff, and improving the user's wearing experience.

The soft rubber material refers to a soft material having a certain degree of ductility and flexibility, including but not limited to, silicone, rubber, soft polyvinyl chloride (PVC), ethylene vinyl acetate copolymer (EVA), polyolefin thermoplastic elastomer (POE), thermoplastic elastomer (TPE), polypropylene (PP), etc.

When external noise enters the interior of earmuff, it needs to pass through the earmuff leather 3 and earmuff sponge 2, and then enter the earmuff airbag 1. As the earmuff airbag 1 is a hollow enclosed airbag, the noise needs to pass through the earmuff airbag 1, earmuff sponge 2, and earmuff leather 3 so as to enter the interior of earmuff and thus enter the human ear. Compared with the conventional earmuff in which external noise only passes through two media, i.e., the earmuff leather 3′ and earmuff sponge 2′, the earmuff according to the present disclosure increases the conducting media of noise by adding the earmuff airbag 1. Thus, the noise will be continuously reduced after passing through different media, thereby enhancing the passive noise reduction ability of the earmuff, and improving the user experience. Moreover, the earmuff airbag 1 comprises at least one hollow enclosed airbag, which provides stronger support for the earmuff than the sponge material and can replace the conventional sponge support for the earmuff.

In sum, the earmuff according to the present disclosure has better noise reduction and support effect by adding the hollow enclosed earmuff airbag 1.

Second Embodiment

The earmuff airbag 1 of the present disclosure may be a single segment enclosed airbag. In the single segment enclosed airbag, there is not an airbag partition, or there is at least one airbag partition.

FIGS. 3 to 5 schematically illustrate embodiments of the single segment enclosed airbag according to the present disclosure. FIG. 3 shows an exterior view of a single segment enclosed airbag according to an embodiment of the present disclosure. FIG. 4 shows a cross-sectional view of a single segment enclosed airbag having not an airbag partition according to an embodiment of the present disclosure. FIG. 5 shows a cross-sectional view and an overall view of a single segment enclosed airbag having multiple airbag partitions according to an embodiment of the present disclosure.

As shown in FIG. 4, the single segment enclosed airbag does not have an airbag partition, and the internal space 1-2 of the airbag is an integral enclosed space.

As shown in FIG. 5, the single segment enclosed airbag has five airbag partitions 1-3 which are independent of each other. The entire internal space 1-2 of the annular airbag is divided into several independent small airbags. By dividing the entire annular earmuff airbag into several independent small airbags, on the one hand, when a small airbag leaks, other intact small airbags can still provide a support force for the entire earmuff airbag; on the other hand, the airbag partitions 1-3 can also enhance the internal support force of the single segment enclosed airbag.

It should be noted that FIG. 5 is only an example of the single segment enclosed airbag, not a limitation of the present disclosure. Any number of airbag partitions 1-3 can be set inside the single segment enclosed airbag.

Third Embodiment

The earmuff airbag 1 of the present disclosure may be a multi-segment enclosed airbag. The segments of the multi-segment enclosed airbag are communicated with each other or independent of each other.

FIGS. 6 to 8 schematically illustrate embodiments of the multi-segment enclosed airbag of the present disclosure. FIG. 6 shows a cross-sectional view (a) and an exterior view (b) of a multi-segment enclosed airbag according to an embodiment of the present disclosure. FIG. 7 shows a cross-sectional view (a) and an exterior view (b) of another multi-segment enclosed airbag according to an embodiment of the present disclosure. FIG. 8 shows a cross-sectional view (a) and an exterior view (b) of still another multi-segment enclosed airbag according to an embodiment of the present disclosure.

As shown in FIGS. 6 to 8, the entire annular airbag may have any number (such as 4, 2, or 1, etc.) of airbag spacings 1-4. The positions and lengths of these airbag spacings 1-4 can be designed as needed. The segments of the multi-segment enclosed airbag may be communicated to each other, as shown in FIG. 6. The two ends of each segment of the airbag are communicated to the airbag spacing 1-4, so that four segments of the airbag are communicated to each other through the airbag spacings 1-4. Alternatively, the segments of the multi-segment enclosed airbag may also be independent of each other, as shown in FIGS. 7 and 8. The two ends of each segment of the airbag are closed, and each segment of the airbag is an independent airbag. The segments are connected through the airbag spacings 1-4, but they are not communicated to each other.

In this embodiment, the entire annular earmuff airbag is divided into several independent small airbags by the airbag spacings 1-4. When a small airbag leaks, other intact small airbags can still provide a support force for the entire earmuff airbag, thereby extending the service life of the earmuff.

Preferably, no matter whether the segments of the multi-segment enclosed airbag are communicated with each other or independent of each other, they are filled with a sponge at each airbag spacing 1-4. The sponge for filling may be integrally manufactured with the earmuff sponge 2 wrapped outside the earmuff airbag and then filled. Alternatively, it may be independently filled in the space of the airbag spacing 1-4. The support force between adjacent small airbags can be enhanced by filling sponges at the airbag spacings 1-4.

In this embodiment, the earmuff airbag may have various wall thicknesses 1-1 to meet different needs of users. For example, a thinner wall thickness can increase the space between the earmuff and the user's ear, and thus enhances sound quality; a thicker wall thickness can enhance the support force of the earmuff, and thus make the earmuff less prone to deformation and more durable.

It should be noted that the above is only examples of the multi-segment enclosed airbag, not a limitation of the present disclosure. The multi-stage enclosed airbags can have any number of segmented airbags in various forms.

Fourth Embodiment

When the earmuff airbag is the single segment enclosed airbag or the multi-segment enclosed airbag in which the segments are communicated with each other, the earmuff airbag 1 of the present disclosure may be formed through integral assembly.

The upper part 1-8 of the earmuff airbag is provided with a skeleton structure, which can provide a certain support force for the earmuff airbag. The bottom of the upper part 1-8 of the earmuff airbag is provided with a slot 1-8-1, and the upper surface of the lower part 1-9 of the earmuff airbag is provided with a boss 1-9-1. The slot 1-8-1 on the bottom of the upper part of the earmuff airbag and the boss 1-9-1 on the upper surface of the lower part of the earmuff airbag are engaged and assembled to form the earmuff airbag 1. Moreover, an installation groove 4-3 for the lower part 1-9 of the earmuff airbag is provided on the inner side of the airbag base 4, the lower part 1-9 of the earmuff airbag is assembled and adhesively bonded into the installation groove 4-3, and thus the airbag base 4 is installed at the bottom of the earmuff airbag 1. The cross-sectional view of the assembly effect is shown in FIG. 16.

Sixth Embodiment

It should be noted that, when the same support force and appropriate comfort can be obtained, the width of root part and the cross-sectional area of the cross-section of the earmuff sponge 2′ in the conventional earmuff are larger than those of the earmuff according to the present disclosure. Therefore, compared with the earmuff according to the present disclosure, the front sound cavity between the ear and the sound generating unit in the conventional earmuff is small and the sound quality is poor.

Referring to FIGS. 14 to 16, the airbag base 4 is also used to accommodate and tighten the earmuff sponge, for example, to tighten the earmuff sponge 2 wrapped around the earmuff airbag 1 within an outer flat flange 4-2 so as to reduce the maximum diameter of root part of the earmuff. FIG. 17 shows a schematic view of the difference in contraction space between the earmuff according to the present disclosure and the conventional earmuff, and the shaded part indicates the portion representing difference in contraction space 5 between them. As shown in FIG. 17, when the same support force and appropriate comfort can be obtained, compared with the conventional earmuff, the earmuff according to the present disclosure can contract smaller at the root part of the earmuff, the width of root part and the cross-sectional area of the earmuff are smaller, thereby increasing the front sound cavity between the sound generating unit of the headphones and the ear, and enhancing the sound quality.

Seventh Embodiment

This embodiment discloses head-mounted headphones that use the earmuff described in the first to sixth embodiments. Compared with conventional head-mounted headphones, by using the earmuff, the head-mounted headphones according to the present disclosure enhances the passive noise reduction ability of headphones, improves the sound quality and stability, and improves the user experience.
