[embodiment]
Below in conjunction with accompanying drawing and execution mode the utility model is described further.
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 and lid in the receiving space to be located at the protecgulum 5 on the shell 3.Conduit 2 communicates with said 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 lid in the back cavity 7 and be located at the inner bag portion 8 that is hollow on the earphone core 4; Inner bag portion 8 is provided with stage portion 81, and inner bag portion 8 is separated into main back cavity 71 and secondary back cavity 72 with back cavity 7, and 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 all communicates with the external world with secondary back cavity 72.Also be provided with the through hole 811 that runs through on it on the stage portion 81, through hole 811 makes main back cavity 71 communicate with secondary back cavity 72.In fact; In the earphone 1 of the utility model; Secondary back cavity 72 is to have separated from main back cavity 71 through inner bag portion 8 in fact, and this just is equivalent to subtract the volume of main back cavity 71, 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 this execution mode, thereby reach the Mid Frequency effect that strengthens earphone 1.In fact, the formation of secondary back cavity 72 is because in inner bag portion 8, be provided with stage portion 81, 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 lets of stage portion 81 in fact.Certainly, the planform of inner bag portion 8 can be other, mainly be in order back cavity 7 to be separated into main back cavity 71 and secondary back cavity 72, but its principle is the same.
In this execution mode, 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 in the utility model, 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 through relief hole 31.More excellent, earphone 1 also is provided with lid and is located at the first damping portion 9 on the through hole 811 and covers the second damping portion 10 on the relief hole 31 that is located at.The setting of the first damping portion 9 is for dustproof, and the setting of the second damping 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 this execution mode, the first damping portion 9 and the second damping 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 the utility model earphone 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, thereby the Mid Frequency effect of the frequency range of the utility model earphone is strengthened, also can not have influence on low-frequency resonant frequency F0 simultaneously at original back cavity.The utility model earphone 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 the utility model earphone is strengthened.Therefore, the frequency range of the utility model earphone is wider, and acoustical behavior is more excellent.
Above-described only is the execution mode of the utility model; 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 utility model creation design; Can also make improvement, but these all belong to the protection range of the utility model.
