Abstract
The utility model discloses novel structure earmuffs. The novel structure earmuffs comprise soundproof sponges and leather covers which are arranged outside the soundproof sponges. By punching on the soundproof sponges, cavities are arranged. By punching on the soundproof sponges, the cavities are arranged, and thus the mutation of an acoustic impedance characteristic on a noise propagation path is realized to improve the soundproof function of the earmuffs. The passive noise reduction of headphones on low and medium frequencies can be improved.
Description
Technical field
The utility model relates to the earphone technical field, more specifically, relates to a kind of new structure ear muff.
Background technology
Headphone is used widely in the field of electronic digital product at present in the earphone technical field, its acoustical quality and stereo set are similar, and other people have been avoided bothering, practical very convenient, conventional headphone all is equipped with ear muff on the loudspeaker protecgulum, be used to reduce the interference that outside noise plays sound to earphone, this ear muff is made up of the tender continuous outside leather sheath of described sound insulation that is installed in of sound insulation, the sound insulation silk floss of ear muff the inside all adopts the isotropic homogeneous structural of a monoblock, the earphone of this structure generally is reasonable at the sound insulation property of high band, in the medium and low frequency section, especially the passive noise reduction of low-frequency range is often not ideal enough, needs to design a kind of ear muff of new structure thus.
The utility model content
In view of the above problems, the purpose of this utility model ear muff that provides a kind of new structure improves the passive noise reduction of headphone in the medium and low frequency section.
For solving the problems of the technologies described above, the utility model by the following technical solutions: a kind of new structure ear muff, comprise the tender continuous outside leather sheath of described sound insulation that is installed in of sound insulation, wherein, punching is provided with cavity on the described sound insulation silk floss.
A kind of optimized technical scheme is punched at interval on the described sound insulation silk floss and is provided with the cavity that several evenly are provided with.
Optimized technical scheme further, being shaped as of described cavity is square, and described cavity evenly forms an annular array at interval.
A kind of optimized technical scheme, being shaped as of described cavity is square, and described each cavity evenly forms plural annular array at interval, and the cavity between described adjacent two annular array is crisscross arranged.
A kind of optimized technical scheme, described sound insulation silk floss is a sponge.
Utilize above-mentioned according to new structure ear muff described in the utility model, because new structure ear muff, comprise the tender continuous outside leather sheath of described sound insulation that is installed in of sound insulation, wherein, punching is provided with cavity on the described sound insulation silk floss, can realize that by be provided with cavity in punching on the sound insulation silk floss sudden change of acoustic impedance characteristic on the noise transmission path improves the effect that ear muff insulates against sound to play, thereby improve the passive noise reduction of headphone in the medium and low frequency section.
Description of drawings
Fig. 1 is the generalized section that the utility model ear muff combines with protecgulum.
Fig. 2 is that the utility model removes the continuous generalized section that combines with protecgulum of sound insulation behind the leather sheath.
Fig. 3 is the continuous generalized section that combines with protecgulum of the sound insulation of another structure of the utility model.
Embodiment
Below with reference to accompanying drawing specific embodiment of the utility model is described in detail.
Embodiment one: as shown in Figure 1, ear muff of the present utility model, comprise sound insulation continuous 2 that is installed on the loudspeaker protecgulum 3 and the leather sheath 1 that is installed in continuous 2 outsides of described sound insulation, wherein, punching is provided with cavity 21 on the described sound insulation silk floss 2, and the sudden change that can realize acoustic impedance characteristic on the noise transmission path is to play the effect that improves ear muff sound insulation.
As shown in Figure 2, as realizing a kind of optimized technical scheme of the utility model, punch at interval on the described sound insulation silk floss 2 and be provided with the cavity 21 that several evenly are provided with, and being shaped as of described cavity 21 is square, described cavity 21 evenly forms an annular array at interval, make the mutation effect of acoustic impedance characteristic better, wherein the described sound insulation silk floss in the utility model is a sponge.
