Abstract
The utility model discloses an earphone sheath which is used by being sleeved on an earphone, fills an external auditory canal together with an earphone and is fixed. The earphone sheath comprises a cavity for accommodating the earphone; a plurality of support bodies are arranged outside an earphone sheath main body; and the support body is in contact with the external auditory canal wall; at least one sound transmission hole is formed at the front end of the earphone sheath and an opening is provided at the back end. The earphone sheath can be used for effectively preventing the occurrence of destabilization or distortional deformation of the earphone sheath due to pressure from the auditory canal. As the sheath is in close contact with the auditory canal wall, no circumferential sound pressure leakage occurs, and sound wave leak is reduced to the maximum limit or is absorbed; and at the same time, the occurrence of looseness or dislocation resulting from vibration and resonance can be prevented, and the earphone sheath is comfort to wear and easy to place and take out.
Description
Technical field
The utility model relates to the earphone servicing unit, relates in particular to a kind of earphone covers of interior aural headphone.
Background technology
In personal sound generating mechanism and hearing aids field, adopt the advantage that interior aural headphone is small and exquisite, hidden, light with it and ectosome does not have electric wire or flexible pipe to fetter of Bluetooth technology transmission signals at present, liked by the user.Components and parts such as the receiver of aural headphone, amplifier, loud speaker are placed in the earphone case all in this, and put into duct, and are very easy to use.Aural headphone in use runs into following situation through regular meeting in this: because the length of user's duct, size and shape are different, the user is difficult to find the earphone that matees with own duct; The acoustic distance people's that loud speaker sends ear-drum also has a segment distance, can cause the loss of sound in transmission course, and about 20% voice signal loss is nearly generally arranged, and the sound that causes passing to ear-drum diminishes; Earphone is difficult to satisfy with duct tight and contacts requirement in addition, causes acoustic pressure to be revealed and external noise gets into duct so that obscures the sense of hearing, also exist earphone to become flexible easily simultaneously in addition deviate from, problem such as earphone material easy damage duct really up to the mark.
The utility model content
The purpose of the utility model is to provide a kind of earphone covers.
An aspect according to the utility model; Earphone covers is sheathed on the earphone; Clog external auditory meatus and fixing jointly with earphone, earphone covers comprises earphone covers main body and the cavity of being located at ccontaining earphone on the earphone covers main body, and earphone covers main body outer setting has some supporters; The earphone covers body front end is provided with the hole, and the earphone covers body rear has opening.Earphone is inserted in the cavity of earphone covers through this opening, the earphone covers front end is offered porose, and the ear-drum place is arrived in order to the transfer voice that earphone speaker is sent in the hole; Earphone covers is embedded external auditory meatus, and the supporter on the earphone covers recovers after receiving the crimp of external auditory meatus wall again.Can prevent effectively that so just earphone receives duct pressure and produces unstability or torsional deformation.Because earphone covers closely contacts with auditory canal wall, do not produce the circumference acoustic pressure and leak, reduce sound wave to greatest extent and leak or " being absorbed ", acoustic reflection is returned the loss of internal auditory meatus or ear-drum minimizing sound.
In some embodiments; For comfortable wearing and the problem that reduces earphone material easy damage duct really up to the mark; Supporter can be designed as the annular brace sheet, this annular brace sheet adopt flexible and whippy macromolecule polymer material through the mould extrusion modling, like rubber or silica gel material.
In some embodiments, not allow acoustic pressure leakage and external noise to get in the duct in order reaching, to obscure the sense of hearing, the annular brace sheet that on the earphone covers outer wall, is provided with is 3～6, and every thickness is 0.2mm～0.4mm, highly is 1mm～2mm; The annular brace sheet is vertical each other with the earphone covers main body.
In some embodiments,, the earphone covers design is certain flexibility for the ease of wearing and winning, corresponding with the physiological make-up of external auditory meatus.
In some embodiments, supporter be positioned at the earphone covers main body outside with the corresponding position of external auditory meatus shape, thereby contact with external auditory meatus and the earphone covers main body provided support.Can prevent effectively that thus loud speaker from producing vibrations or resonance causes earphone to come off.
In some embodiments, the spacing distance 3mm～10mm of described each annular brace sheet forms the inside and outside isolated barrier of multiple tracks duct.
Description of drawings
Fig. 1 is the assembly structure sketch map of the utility model embodiment earphone covers;
Fig. 2 is the cross-sectional view of the utility model embodiment earphone covers;
Fig. 3 is the cross-sectional view of the utility model embodiment earphone covers user mode.
Embodiment
Please refer to Fig. 1 to Fig. 3, as shown in the figure, the earphone covers main body 1 of the utility model is slight curving, and is approximate with the physiological make-up of external auditory meatus.The point diameter of earphone covers main body 1 is less than the rear end diameter and be cone shape, and earphone covers main body 1 has a cavity 2, and the front end of earphone covers main body 1 is provided with transfer voice hole 3, and transfer voice hole 3 can have a plurality of as required.Earphone covers main body 1 rear end has opening 4.Through this opening 4 earphone 5 is inserted in the cavity 2 of earphone covers main body 1.
In the outer setting of earphone covers main body 13 circles or 5 circles or 6 circle thickness being arranged is 0.2mm or 0.34mm or 0.4mm, highly is the annular brace sheet 6 of 1mm or 1.5mm or 2mm.Each annular brace sheet 6 be spaced apart 3mm or 7mm or 10mm, and adopt comparatively softness and rubber-like elastomeric material or plastic cement or silica gel material through the mould extrusion modling.Annular brace sheet 6 is arranged on the outside and the corresponding position of external auditory meatus of earphone covers main body 1, so that be resisted against on the external auditory meatus, thus earphone covers main body 1 is provided support.
During assembling earphone 5 is embedded into cavity 2 internal fixation of earphone covers main body 1 through opening 4, the reinforcement 7 that is arranged on earphone covers main body 1 open rearward end 4 places lock onto earphone 5 in the cavity 2, and guarantees that the working face 8 of loud speaker aims at transfer voice holes 3.
When the earphone covers that assembles was embedded duct, the ring segment support chip 6 on the earphone covers main body 1 recovered after receiving the crimp of external auditory meatus wall again, and annular brace sheet 6 closely contacts with auditory canal wall when the time comes.Can prevent effectively that so just earphone covers receives duct pressure and produces unstability or torsional deformation.Because earphone covers closely contacts with duct, do not produce the circumference acoustic pressure and leak, reduce sound wave to greatest extent and leak or " being absorbed ".While can prevent to shake and resonate and cause generation, comfortable wearing loosening or dislocation, is easy to place and take out.
Above-described only is a kind of execution mode of the utility model.For the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement; These all belong to the protection range of the utility model, and in like manner the earphone covers of the utility model can also be applied to personal stereo or have the mobile phone of Bluetooth function, the earphone of phone.
