Embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

See also Fig. 3 a, the utility model toneable earphone 1 comprises back casing 11, procapsid 12 and loudspeaker monomer 13, and the sound that the loudspeaker monomer 13 of this tuning earphone 1 sends spreads out of by procapsid 12.

See also Fig. 3 a-6, the back casing 11 of toneable earphone 1 is rotatably connected with procapsid 12, offers cavity 111 in this back casing 11, and this back casing 11 convexes with block 112 towards an end face of this procapsid 12.Particularly, the cylindrical substantially structure of this back casing 11, the cavity 111 of back casing 11 matches with the shape of back casing 11, that is: cavity 111 is also cylindrical.Block 112 is circular arc, and is convexly set on the end face of procapsid 12.The procapsid 12 of this toneable earphone 1 comprises acoustic cylindrical shell 121 and holding section 122, and this holding section 122 is expanded outwardly by the end of this acoustic cylindrical shell 121 to be extended and form.In the present embodiment, the end of acoustic cylindrical shell 121 extends to form holding section 122 outward along the radial direction of acoustic cylindrical shell 121.This holding section 122 offers cavity 1221, offers sound-delivery channel 1211 along the bottom of this cavity 1221, and this sound-delivery channel 1211 runs through this acoustic cylindrical shell 121.This sound-delivery channel 1211 forms groove with this cavity 1221, and this groove is connected with the cavity 111 of back casing 11.Offer through

hole

1222a, 1222b and 1222c in the cavity 1221 of the holding section 122 of this procapsid 12, described through

hole

1222a, 1222b and 1222c arrange counterclockwise, that is: described through hole 1222 is opened in described holding section 122 and connects with described cavity 1221.The block 112 of back casing 11 is rotatably connected in the cavity 1221 of procapsid 12, and realization back casing 11 is rotatably connected with procapsid 12.At length, three through

hole

1222a, 1222b that this procapsid 12 is offered and the aperture of 1222c are different, in the present embodiment, these three through

hole

1222a, 1222b and 1222c are the isometrical distribution in the center of circle with the groove, and the aperture of three through

hole

1222a, 1222b and 1222c is counterclockwise and reduces successively.When back casing 11 during with procapsid 12 relative rotations, the block 112 that can adjust back casing 11 blocks or opens through hole through

hole

1222a, 1222b and the 1222c on the procapsid 12.Described back casing 11 has three kinds of situations respectively with procapsid 12 relative rotations: 1. back casing 11 is static, rotates procapsid 12; 2. procapsid 12 is static, rotates back casing 11; 3. procapsid 12 rotates with back casing 11, and this procapsid 12 relatively rotates with back casing 11.See also Fig. 3 b, when the block 112 of back casing 11 rotates to Fig. 3 b position, block 112 shelters from through hole 1222a, and through

hole

1222b and 1222c are not blocked.In other embodiment of the present utility model, rotation back casing 11, the block 112 of back casing 11 can block two through

hole

1222a and 1222b, also can block three through

hole

1222a, 1222b and 1222c.

Need to prove that the described through hole of the utility model toneable earphone 1 is not limited to the quantity of three through holes in the foregoing description, number of openings can be two or more any amount, is determined on a case-by-case basis.In addition, the aperture of through hole is not limited to above-mentioned being counterclockwise and reduces successively, and in other embodiments, the aperture of through hole also can be to be and reduces successively clockwise or irregular arranging, and is determined on a case-by-case basis.

See also Fig. 4 and Fig. 7-8, the loudspeaker monomer 13 of toneable earphone 1 comprises sound film 131, voice coil loudspeaker voice coil 132, magnet 133, China this 134, radome 135, catch 136 and connector 137.The one side of this radome 135 concaves and forms groove 1351, sound film 131, this 134 is arranged at voice coil loudspeaker voice coil 132, magnet 133 and China in this groove 1351, wherein, this voice coil loudspeaker voice coil 132 is circular, magnet 133 and Hua Si 134 are arranged at this voice coil loudspeaker voice coil 132 centers, and the one side of sound film 131 is towards the groove setting of procapsid 12, and the relative voice coil loudspeaker voice coil 132 of the another side of this sound film 131 is provided with.Offer several bleeder ports 1352 on the radome 135, catch 136 blocks this bleeder port 1352, and this connector 137 is installed in the another side of radome 135.

With reference to figure 3a-8, connector 137 energisings when loudspeaker monomer 13, signal of telecommunication flowing through voice coil 132, voice coil loudspeaker voice coil 132 produce magnetic force change and with the magnetic field interaction of magnet 133, voice coil loudspeaker voice coil 132 is attracted by magnet 133 along with the electronic signal variation or repels, and drive sound film 131 and move, make compression thus or the air that loosens and send sound wave.Because the procapsid of toneable earphone 1 has been offered through

hole

1222a, 1222b and 1222c, by rotating back casing 11 or/and procapsid 12, block 112 blocks or opens the through hole 122 on the procapsid 12, thereby change the stream pressure of earphone inside, and adjustment loudspeaker monomer 13 sounds are to the distance of ear, change the time difference that sound produced, and then adjust the spatial impression of sound.See also Fig. 3 a-3b, when block 112 blocks two through

hole

1222a and 1222b on the procapsid 12, the sound medium and low frequency line that the sound medium and low frequency line proportion by subtraction that this toneable earphone 1 sends earphone commonly used sends is divided few; When 112 of blocks block a through hole 1222a on the procapsid 12, the sound medium and low frequency line that the earphone when the sound medium and low frequency line proportion by subtraction that this toneable earphone 1 sends is blocked two through

hole

1222a and 1222b sends is divided few.In other embodiment of the present utility model, block 112 also can block three through

hole

1222a, 1222b and 1222c.
