Abstract
The utility model discloses an improved in-ear earphone, belonging to the technical field of general earphones; the earphone comprises an earphone shell (102), a loudspeaker body (103) arranged in the earphone shell and a sound outlet hole (101) arranged in the earphone shell (102), wherein the sound outlet hole (101) is composed of at least two sound outlet pipe bodies (104) with different inner hole sizes. The utility model discloses a sound outlet (101) become to constitute by at least two acoustic component, increase sound resonance circuit at the high band of earphone, widen the effective range of original high frequency, make sound fine more, happy.
Description
Technical field:
The utility model belongs to general earphone technical field, particularly a kind of improvement In-Ear Headphones.
Background technology:
Common In-Ear Headphones on the market generally is made up of earphone case, loudspeaker and phonate hole now, but its phonate hole shape all is the same through hole of diameter, be that an acoustic element and loudspeaker form resonant tank, can not further regulate needed high frequency response, so the auditory effect of high pitch just is restricted.
Summary of the invention:
The purpose of this utility model is intended to overcome the deficiencies in the prior art, provides a kind of simple in structure, the In-Ear Headphones that cost is low and tonequality is good.
The utility model is mainly realized goal of the invention by following technical solution:
A kind of improvement In-Ear Headphones, it comprises earphone case (102), is arranged at the speaker body (103) in the earphone case and is located at the interior phonate hole (101) of earphone case (102) that described phonate hole (101) is made up of the through hole that at least two sector holes directly vary in size.
Described phonate hole (101) is integrally formed with earphone case (102).
Described phonate hole (101) is fixed in the earphone case (102).
Described phonate hole (101) is combined by large aperture through hole and through hole space, small-bore.
Described phonate hole (101) is outwards combined according to diameter from the lining from small to large by large aperture through hole and small-bore through hole.
Described phonate hole (101) is outwards combined according to diameter from the lining from big to small by large aperture through hole and small-bore through hole.
One section through hole of speaking that the utility model is the same with diameter becomes the combination of at least two sections through holes of speaking of different-diameter, so just the through hole of speaking is become at least two acoustic elements from an acoustic element; This just increases high frequency acoustic resonance loop again on the basis of original high frequency, the effective bandwidth of broadening high band makes sound sound more very thin, and range is broad more.
Description of drawings:
A kind of example structure schematic diagram of Fig. 1 the utility model;
Fig. 2 the utility model is planted an example structure schematic diagram in addition;
A kind of example structure figure of Fig. 3 the utility model phonate hole;
The another kind of example structure figure of Fig. 4 the utility model phonate hole.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model by earphone case 102, be arranged at the speaker body 103 in the earphone case 102 and the phonate holes 101 be located in the earphone case 102 are formed.In the present embodiment, phonate hole 101 is integrally formed with earphone case 102.By as can be known embodiment illustrated in fig. 1, the utility model phonate hole 101 is made up of the through hole that three sections internal diameters vary in size, and prior art then is made up of one section equirotal through hole of internal diameter, so just phonate hole 101 is become three acoustic elements from an acoustic element; This just increases by two high frequency acoustic resonance loops again on the basis of original high frequency, the effective bandwidth of broadening high band makes high pitch sound more very thin, and range is broad more, and great changes will take place to make acoustical quality.
Shown in Figure 2 is the another kind of embodiment of the utility model.In the present embodiment, phonate hole 101 places go out sound pipe 104 by bonding, weld or mode such as be spirally connected is fixed on the earphone case 102.
As shown in Figure 3, phonate hole 101 of the present utility model is made up of the tube wall 201 of speaking, the through hole 101 of speaking is made up of two sections internal diameter through holes not of uniform size, effectively an original acoustic element is become two acoustic elements, thereby reaches different tonequality and acoustics.As shown in Figure 4, phonate hole 101 of the present utility model is made up of the tube wall 201 of speaking, the through hole 101 of speaking is made up of four sections internal diameter through holes not of uniform size, effectively an original acoustics original paper is become four acoustics original papers, thereby reaches different tonequality and acoustics.In addition, each section of forming phonate hole 101 through hole of speaking can require according to the difference to earphone tonequality outwards be made up from small to large according to diameter from the lining by large through-hole and small through hole, also can make up from big to small, can also size interval make up.That is to say through-hole structure in the phonate hole that In-Ear Headphones uses, should be according to equivalent volume, earphone and horn chamber body bulk and the high frequency requirement of loudspeaker, from above several basic combinations, choose the structure of phonate hole 101, to reach the requirement of needed high frequency acoustics, the profile of phonate hole 101 and length also can design as required.
In addition, according to Principles of Acoustics, the utility model is circular, oval or square with the Cross-section Design of phonate hole 101, to reach different acoustics, certainly for cooperating the earphone appearance design, can be other shape with the Cross-section Design of phonate hole 101 also, the shape of phonate hole 101 also can be designed to arc and not exclusively be orthoscopic certainly.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
