Abstract
The utility model discloses an earphone. The earphone includes a shell and a loudspeaker single body. A resonant cavity is formed in the shell; the back of the shell is fixedly provided with a handle extending downwards; a through hole communicated with the resonant cavity is formed in the lower surface of the handle; the lower surface of the handle is provided with two volume adjustment holes which are communicated with the resonant cavity and the through hole, wherein the volume adjustment holes are upwardly formed at two sides of the through hole; the diameter of the volume adjustment holes is smaller than the diameter of the through hole; and the loudspeaker single body is arranged in the resonant cavity. According to the earphone of the utility model, the lower surface of the handle is provided with two volume adjustment holes which are upwardly formed at the two sides of the through hole, and the diameter of the volume adjustment holes is smaller than the diameter of the through hole, and therefore, air will not be blocked by transmission cables when flowing, and thus, inconsistency in bass auditory sensing which is caused by the influence of the transmission cables can be avoided.
Description
Technical field
The utility model relates to a kind of earphone, especially relates to one and can avoid transmission cable to affect the inconsistent earphone of bass sense of hearing.
Background technology
Existing a kind of 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 a handle to downward-extension, and the lower surface of handle is upwards offered a through hole being communicated with resonant cavity; Horn single body is installed in resonant cavity; Line gear is installed in the lower end of handle and by the lower end sealing of through hole, 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 adjusts after line keeps off a definite position and starts normal use according to the auditory perception of self, now earphone has a definite bass auditory perception, due to transmission cable in through wires hole along with user's activity meeting is in diverse location, cause transmission cable in various degree stop through wires hole, thereby impact enters through hole from through wires hole and 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 overcome above-mentioned deficiency of the prior art, and a kind of earphone is provided, and this earphone can avoid transmission cable to affect the inconsistent phenomenon of bass sense of hearing.
To achieve these goals, the utility model provides a kind of earphone, comprises a housing and a horn single body.Enclosure interior is formed with a resonant cavity, housing rear portion is installed with a handle to downward-extension, the lower surface of handle is upwards offered a through hole being communicated with resonant cavity, the lower surface of handle is upwards offered respectively a sound regulating hole being communicated with resonant cavity and through hole in through hole both sides, the diameter of sound regulating hole is less than through-hole diameter; Horn single body is installed in resonant cavity.
As mentioned above, the utility model earphone is upwards offered respectively a sound regulating hole being communicated with bass inner chamber by the lower surface of handle in through hole both sides, and the diameter of sound regulating hole is less than through-hole diameter, while making Air Flow, can not be transmitted cable and stop, thereby avoid transmission cable to affect the inconsistent phenomenon of bass sense of hearing.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with execution mode and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1 and Fig. 2, the utility model earphone comprises housing 10 and a horn single body 20.
Refer to Fig. 2 and Fig. 3, described housing 10 inside are formed with a resonant cavity 13, horn single body 20 is installed in resonant cavity 13, housing 10 rear portions are installed with a cylindrical handle 121 to downward-extension, the lower surface of handle 121 is upwards offered a through hole 122 being communicated with resonant cavity 13, the lower surface of handle 121 is upwards offered respectively a sound regulating hole 123 being communicated with resonant cavity 13 and through hole 122 in through hole 122 both sides, the diameter of sound regulating hole 123 is less than through hole 122 diameters.Particularly, housing 10 comprises a fore shell 11 and one and the back cover 12 that mutually covers of fore shell 11, horn single body 20 is located between fore shell 11 and back cover 12, between horn single body 20 and fore shell 11, forms high pitch inner chamber 131, between horn single body 20 and back cover 12, forms bass inner chamber 132.On described fore shell 11, offer several senders 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 is upwards offered the described through hole 122 being communicated with bass inner chamber 132, and the lower surface of handle 121 is upwards offered respectively a sound regulating hole 123 being communicated with bass inner chamber 132 in through hole 122 both sides.The lower surface of handle 121 is irregular inclined plane, and through hole 122 lower ends are connected with a transmission cable (not shown).
Refer to Fig. 1 to Fig. 3, in the time 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, in the time that transmission cable uses generation bending, be less than through hole 122 diameters by the diameter of sound regulating hole 123, transmission cable can only be in through hole 122 inner bendings or activity, ensure that transmission cable can not move in sound regulating hole 123, so Air Flow enters in resonant cavity 13 via the sound regulating hole 123 of through hole 122 both sides, thereby regulate the extraneous size that enters bass inner chamber 132 air-flows to regulate the Kong Qi Ya Li Time of bass inner chamber 132 by sound regulating hole 123, can not be transmitted cable stops, avoid transmission cable to affect the inconsistent phenomenon of bass sense of hearing.
Refer to Fig. 4, this figure has intercepted in the frequency range (20Hz ~ 20kHz) of human auditory system, the frequency curve of the utility model earphone in the time having or not sound regulating hole 123 state of through hole 122 both sides.In the time of sound regulating hole 123 without through hole 122 both sides, transmission cable can stop this through wires hole, affects air mass flow, and now, a little less than bass, the frequency response curve of its bass is curve I in figure and shows; In the time having the sound regulating hole 123 of through hole 122 both sides, now low loudness of a sound, the frequency response curve of its bass is curve II in figure and shows.
As mentioned above, the utility model earphone is upwards offered respectively a sound regulating hole 123 being communicated with bass inner chamber 132 by the lower surface of handle 121 in through hole 122 both sides, and the diameter of sound regulating hole 123 is less than through hole 122 diameters, while making Air Flow, can not be transmitted cable and stop, thereby avoid transmission cable to affect the inconsistent phenomenon of bass sense of hearing.
