[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
Shown in Fig. 1-4, a kind of earphone 1, it comprises conduit 2, be set in the shell 3 with receiving space (not label) on the conduit 2, place earphone core 4 in the receiving space and lid to be located at protecgulum 5 on the shell 3.Conduit 2 communicates with described receiving space, is used for lead 24 is incorporated in the receiving space, lead 24 is formed with earphone core 4 be electrically connected.Earphone core 4 surrounds ante-chamber 6 jointly with protecgulum 5, and earphone core 4 surrounds back cavity 7 jointly with shell 3.Wherein, also be provided with the inner bag portion 8 that is hollow that is located on the earphone core 4 of covering in the back cavity 7, inner bag portion 8 is provided with stage portion 81, inner bag portion 8 is separated into main back cavity 71 and secondary back cavity 72 with back cavity 7, inner bag portion 8 surrounds main back cavity 71 jointly with earphone core 4, inner bag portion 8 surrounds secondary back cavity 72 jointly with shell 3, and main back cavity 71 and secondary back cavity 72 all communicate with the external world.Also be provided with the through hole 811 that runs through on it on the stage portion 81, through hole 811 communicates main back cavity 71 and secondary back cavity 72.In fact, in the earphone 1 of the present invention, secondary back cavity 72 is to have separated from main back cavity 71 by inner bag portion 8 in fact, this just is equivalent to subtract the volume of main back cavity 71, pass through said structure, the operating frequency peak value of earphone 1 can be adjusted near the 3KHz, thereby has strengthened the Mid Frequency effect when earphone 1 is worked.If have only back cavity 7 to have only 71 1 cavitys of main back cavity and only reduce the volume of main back cavity 71 separately, equally also can improve the Mid Frequency effect, but can influence low-frequency resonant frequency F0 simultaneously.Therefore, be that the volume that main back cavity 71 reduces is divided into secondary back cavity 72 in the present embodiment, thereby reach the Mid Frequency effect that strengthens earphone 1.In fact, the formation of secondary back cavity 72 is because be provided with stage portion 81 in inner bag portion 8, is equivalent to a kind of effect of stepping down, thereby makes inner bag portion 8 and shell 3 surround secondary back cavity 72, and the space of secondary back cavity 72 is the bit space that allows of stage portion 81 in fact.Certainly, the planform of inner bag portion 8 can be other, mainly be for back cavity 7 being separated into main back cavity 71 and secondary back cavity 72, but its principle is the same.
In the present embodiment, be provided with partition wall 21 in the conduit 2, partition wall 21 is separated into conduit 22 and the sound guide tube 23 adjacent with conduit 22 with conduit 2.Be among the present invention, conduit 2 is a double pipe structure.Conduit 22 is incorporated into earphone core 4 with lead 24, and sound guide tube 23 1 ends communicate with the external world, and its other end communicates with main back cavity 71.The increase of sound guide tube 23 is equivalent to the acoustic mass that increases earphone 1, and the acoustic mass increase can make the low-frequency resonant frequency F0 of earphone 1 reduce, and then has strengthened the low-frequency range effect when earphone 1 is worked.
Also be provided with the relief hole 31 that runs through on it on the shell 3, secondary back cavity 72 communicates with the external world by relief hole 31.More excellent, earphone 1 also is provided with lid and is located at first damper portion 9 on the through hole 811 and covers second damper portion 10 that is located on the relief hole 31.The setting of first damper portion 9 is for dustproof, and the setting of second damper portion 10 is in order to regulate the acoustic impedance of secondary back cavity 72, the secondary back cavity 72 and the acoustic impedance of sound guide tube 23 to be complementary.Concrete, in the present embodiment, first damper portion 9 and second damper portion 10 are gauze or sponge or adjustable sound paper.Can certainly be other, but its principle is the same.
Compare with correlation technique, the inner bag portion that earphone of the present invention is being set up in back cavity, thereby back cavity is separated into main back cavity and secondary back cavity, be equivalent to reduce its volume basically and the volume that will reduce is set up into another back cavity at original back cavity, thereby the Mid Frequency effect of the frequency range of earphone of the present invention is strengthened, also can not had influence on low-frequency resonant frequency F0 simultaneously.Earphone of the present invention has also been set up in conduit and has been made the main back cavity sound guide tube that communicates with the external world, the increase of sound guide tube is equivalent to the acoustic mass that increases earphone, and then be equivalent to the low-frequency resonant frequency that reduces earphone, thereby the low-frequency range effect of the frequency range of earphone of the present invention is strengthened.Therefore, the frequency range of earphone of the present invention is wider, and acoustical behavior is more excellent.
Above-described only is embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
