Abstract
The utility model provides a kind of acoustic filter for customizing earphone, this acoustic filter being used for customizing earphone comprises: the silica gel outer tube with hollow cavity, be nested at least three plastic tubes in described silica gel outer tube, and described at least three plastic tube intervals are arranged.The beneficial effects of the utility model are: form stepped configuration by the hollow cavity of silica gel outer tube and the hollow cavity of plastic tube, by this structure, can realize the decay of high frequency and increase the sense of low frequency atmosphere.
Description
Technical field
The utility model relates to the art field of acoustics, refers more particularly to a kind of acoustic filter for customizing earphone.
Background technology
Along with improving constantly of quality of life, people require more and more to come to quality of life, in order to can better music appreciating, people often do not meet the music effect of existing earphone, people often customize earphone to improve the appreciation effect of music for this reason, but the earphone of customization is easy owing to being directly connected on stereo set in use, also easily there is high-frequency cacophony when it uses, have influence on user's music effect in use.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of acoustic filter for customizing earphone.
The utility model is realized by above technical scheme:
The utility model provides a kind of acoustic filter for customizing earphone, this acoustic filter being used for customizing earphone comprises: the silica gel outer tube with hollow cavity, be nested at least three plastic tubes in described silica gel outer tube, and described at least three plastic tube intervals are arranged.
Preferably, described plastic tube is polyvinyl chloride pipe.
Preferably, the number of described plastic tube is three.
Preferably, the length of described silica gel outer tube is 15mm, external diameter 3mm, internal diameter 2mm; The length of described plastic tube is 3mm, and external diameter is 2mm, and internal diameter is 1mm.
The beneficial effects of the utility model are: form stepped configuration by the hollow cavity of silica gel outer tube and the hollow cavity of plastic tube, by this structure, can realize the decay of high frequency and increase the sense of low frequency atmosphere.
Accompanying drawing explanation
Fig. 1 is the structural representation of the acoustic filter for customizing earphone that the utility model provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, with the right side by reference to the accompanying drawings and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is the structural representation of the acoustic filter for customizing earphone that the utility model provides.
The utility model embodiment provides a kind of acoustic filter for customizing earphone, this acoustic filter being used for customizing earphone comprises: the silica gel outer tube 1 with hollow cavity 11, be nested at least three plastic tubes 2 in described silica gel outer tube 1, and described at least three plastic tubes 2 interval is arranged.
In the above-described embodiments, by adopting silica gel outer tube 1 and being nested in silica gel outer tube 1 and spaced at least three plastic tubes 2 form acoustic filter, wherein, the hollow cavity 11 of silica gel outer tube 1 and the hollow cavity of plastic tube 2 form a terrace structure, sound, when by this terrace structure, can realize the decay of high frequency and increase the sense of low frequency atmosphere.And because the hardness of plastic tube 2 is higher than the hardness of silicone tube, thus make this acoustic filter, can reach the more high frequencies of decay, in addition, the number of plastic tube 2 is more than or equal to three, can form decay repeatedly.
Concrete, plastic tube 2 can adopt the plastic raw materials of unlike material to make, and preferably, this plastic tube 2 is polyvinyl chloride pipe, has stronger hardness, and cheap, is convenient to the cost reducing product.
In the above-described embodiments, the number of described plastic tube 2 is not less than three, and preferably, the number of described plastic tube 2 is three.The structure repeatedly decaying and can simplify as far as possible acoustic filter can be realized.
Concrete, the length of described silica gel outer tube 1 is 15mm, external diameter 3mm, internal diameter 2mm; The length of described plastic tube 2 is 3mm, and external diameter is 2mm, and internal diameter is 1mm.In use, the bore of sound in 15mm is respectively, and propagates in the stepped configuration of 1mm, 2mm, 1mm, 2mm, 1mm, by this structure, can realize the decay of high frequency and increase the sense of low frequency atmosphere.
Can be found out by foregoing description, the ascending order filter that the present embodiment provides forms stepped configuration by the hollow cavity 11 of silica gel outer tube 1 and the hollow cavity of plastic tube 2, by this structure, can realize the decay of high frequency and increase the sense of low frequency atmosphere.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
