Description
Technical field
The utility model belongs to ear phone technology field, and specifically a kind of transmission cable of avoiding affects the inconsistent earphone of bass sense of hearing.
Background technology
In prior art, earphone comprises a housing, a horn single body and line gear.Enclosure interior is formed with a resonant cavity, and housing rear portion is installed with one to the handle of downward-extension, and the lower surface of handle upwards offers a through hole be communicated with resonant cavity; Horn single body is installed in resonant cavity; Line gear is installed in the lower end of handle and is sealed the lower end of through hole, and line gear lower end offers a through wires hole, and through wires hole is connected with a transmission cable.
But, above-mentioned earphone in use, user according to self auditory perception adjustment line keep off one determine position after start normal use, now earphone has the bass auditory perception determined, due to transmission cable in through wires hole along with the activity of user can be in diverse location, cause transmission cable stop through wires hole in various degree, impact enters through hole from through wires hole thus enters the air mass flow in resonant cavity, produce different dampings, and then produce different bass experience, cause sense of hearing inconsistent.
Utility model content
The purpose of this utility model is to solve deficiency of the prior art, provides a kind of transmission cable of avoiding to affect the inconsistent earphone of bass sense of hearing.
Earphone of the present utility model comprises a housing and a horn single body, enclosure interior is formed with a resonant cavity, housing rear portion is installed with one to the handle of downward-extension, the lower surface of handle upwards offers a through hole be communicated with resonant cavity, the lower surface of handle is in through hole both sides respectively to above offering a sound regulating hole be communicated with through hole with resonant cavity, and the diameter of sound regulating hole is less than through-hole diameter; Horn single body is installed in resonant cavity.
Preferably, described housing comprises the back cover that a fore shell and one and fore shell cover mutually; Described horn single body is located between fore shell and back cover, forms high pitch inner chamber between horn single body and fore shell, forms bass inner chamber between horn single body and back cover.
Preferably, described handle is fixedly arranged on the rear portion of back cover, described through hole and bass inner space.
The utility model earphone by the lower surface of handle in through hole both sides respectively to above offer one with the sound regulating hole of bass inner space, and the diameter of sound regulating hole is less than through-hole diameter, cable can not be transmitted when air is flowed stop, thus avoid transmission cable to affect the inconsistent phenomenon of bass sense of hearing.In addition, the utility model is practical, and production cost is not high, is adapted at correlative technology field and promotes the use of.

Fig. 1 is the utility model structural representation;
Fig. 2 is II-II profile of the utility model earphone;
Fig. 3 is the three-dimensional exploded view of the utility model earphone.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing, make above-mentioned and other object of the present utility model, characteristic sum feature will be more clear.Reference numeral identical in whole accompanying drawing indicates identical part.Deliberately do not draw accompanying drawing in proportion, focus on explaining purport of the present utility model.
As shown in Figure 1 and Figure 2, the utility model earphone comprises housing 10 and a horn single body 20.
As shown in Figure 2 and Figure 3, the utility model housing 10 inside is formed with a resonant cavity 13, horn single body 20 is installed in resonant cavity 13, housing 10 rear portion is installed with one to the cylindrical handle 121 of downward-extension, the lower surface of handle 121 upwards offers a through hole 122 be communicated with resonant cavity 13, the lower surface of handle 121 is in through hole 122 both sides respectively to above offering a sound regulating hole 123 be communicated with through hole 122 with resonant cavity 13, and the diameter of sound regulating hole 123 is less than through hole 122 diameter.
Particularly, housing 10 comprises the back cover 12 that a fore shell 11 and one and fore shell 11 cover mutually, horn single body 20 is located between fore shell 11 and back cover 12, forms high pitch inner chamber 131 between horn single body 20 and fore shell 11, forms bass inner chamber 132 between horn single body 20 and back cover 12.Described fore shell 11 offers several sender 111, the rear portion of described back cover 12 is installed with the described cylindrical handle 121 to downward-extension, the lower surface of handle 121 upwards offers the described through hole 122 be communicated with bass inner chamber 132, the lower surface of handle 121 in through hole 122 both sides respectively to above offering a sound regulating hole 123 be communicated with bass inner chamber 132.The lower surface of handle 121 is irregular inclined plane, and through hole 122 lower end is connected with a transmission cable.
As Fig. 1, Fig. 2, shown in Fig. 3, when there is vibration in the horn single body 20 of the utility model earphone, pressure in resonant cavity 13 can change, meanwhile, the pressure of bass inner chamber 132 also can change, when transmission cable uses generation bending, through hole 122 diameter is less than by the diameter of sound regulating hole 123, transmission cable can only in through hole 122 inner bending or activity, ensure that transmission cable can not move in sound regulating hole 123, so air flowing enters in resonant cavity 13 via the sound regulating hole 123 of through hole 122 both sides, thus when regulating the external world enter the size of bass inner chamber 132 air-flow and regulate the air pressure of bass inner chamber 132 by sound regulating hole 123, cable can not be transmitted stop, avoid transmission cable and affect the inconsistent phenomenon of bass sense of hearing.
Obviously, a lot of detail has been set forth in above-mentioned explanation so that fully understand the technical solution of the utility model.But above description is only preferred embodiment of the present utility model, the utility model can be much different from alternate manner described here to implement, and therefore the utility model is not by the disclosed concrete restriction implemented above.Any those skilled in the art are not departing under technical solutions of the utility model ambit simultaneously, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Every content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solutions of the utility model protection.
