Below, in conjunction with the embodiments, the utility model done further specifying.
Fig. 1 is the schematic diagram of the stereophone of the utility model embodiment.
As shown in Figure 1, the stereophone of present embodiment, it comprises: pair of right and left stereophone main body 1, earplug 2, be used to link the plug 7 of music player etc., earphone cord 3 and the sound attenuation mechanism 6 slidably with two branch lines part of the 1st earphone cord 31 that links pair of right and left stereophone main body 1 and plug 7 and the 2nd earphone cord, wherein said earplug 2 is configured in the sound guide tube front end, the sound that described sound guide tube is used for being built in the speaker unit of the headset main body 1 ear external auditory meatus that leads effectively; Described slidably sound attenuation mechanism 6 has and is arranged at engaging or separate the binding parts on 3 liang of branch lines parts of earphone cord.
As shown in Figure 1, be divided on the position of the 1st earphone cord 31 and 32 two branch lines of the 2nd earphone cord, be provided with earphone cord furcation 4, and be provided with earphone cord slide fastener 5 between earphone cord furcation 4 and the sound attenuation mechanism 6 at the earphone cord 3 of plug 7 sides.
In addition, the state the when stereophone that Fig. 2 illustrates the utility model embodiment is worn, Fig. 3 illustrates the state of stereophone before being worn to ear of the utility model embodiment.
Also have, Fig. 4 is the detailed icon that is arranged at the sound attenuation mechanism 6 on 3 liang of branch line parts of earphone cord, wherein, the outside drawing of the sound attenuation mechanism 6 when Fig. 4 (a) is connecting state, Fig. 4 (b) is the side view of sound attenuation mechanism 6.
Below, stereophone of the present utility model is described.
At first, stereophone has auris dextra usefulness and left ear headset main body 1, different sound about feasible can the broadcast.In addition, headset main body 1 is formed by resin or metal, pottery etc., and has the electroacoustic transducer according to the audio-signal-driven oscillating plate in the headset main body 1, i.e. driver element (or speaker unit).
In addition, in the plug-in type stereophone, the sound guide tube that earplug 2 is installed is outstanding from the driver element convex, when being worn over headset main body 1 on the ear, rubber-like earplug 2 can insert the external auditory meatus of ear securely, earplug 2 is by strain, thereby makes the major part of earplug 2 be close to the inner face of external auditory meatus, improved the sealing of the external auditory meatus between sound guide tube and eardrum.Therefore, the part that the sound that produces from driver element in the headset main body 1 is revealed during conducting to the process of eardrum seldom, so can with sound loss seldom transmit sound from the low frequency to the high frequency in stable conditionly.
Also have, under the situation of stereophone, owing to do not have as being worn on the required headband of head etc. in the headphone, when being worn over headset main body 1 on the ear, friction that earphone cord 3 is subjected to or vibration meeting are directly passed in the ear that keeps headset main body 1 by headset main body 1, and become undesirable noise.
And, in the plug-in type stereophone,, therefore can hear bigger noise owing to the sealing that has improved by rubber-like earplug 2 between headset main body 1 and external auditory meatus.
Particularly, under headset main body 1 is worn over state on the ear, when the big noise that produces by earphone cord is an earphone cord 3 with friction such as clothes or face or lax earphone cord 3 hang over generation when causing earphone cord 3 to be tightened up on hand or the luggage, owing to being hears as unexpected big noise, therefore very unhappy, and hinder the audiovisual of comfortable music.
At the problems referred to above, in order to make the vibration of biography to headset main body 1, before being sent to headset main body 1, significantly reduce, when being worn over headset main body 1 on the ear, must make earphone cord 3 be in the state of firm stable to the part the headset main body 1, even so that produce or earphone cord 3 also be can't hear big noise when being tightened up at aforesaid fricative from the vibration generating unit.
Therefore, in two branch lines of earphone cord 3 part, promptly the 1st earphone cord 31 between 1 and the 2nd earphone cord 32 are provided with the sound attenuation mechanism 6 with the binding parts that can engage or separate from earphone cord furcation 4 to headset main body, as shown in Figure 2, when headset main body 1 is worn on the ear, if the linking part of sound attenuation mechanism 6 is connected in the wearer's of headset main body 1 neck back, because in the earphone cord 3 of plug 7 sides or the weight of player, sound attenuation mechanism presents the state that is close to the neck back, thereby makes the part of earphone cord 3 keep stable.
As mentioned above, because the 1st earphone cord 31 and the 2nd earphone cord 32 that link plug 7 and headset main body 1 are stably remained on apart from headset main body 1 wearer's neck back and from the very approaching position of ear, can reduce significantly because the noise that is brought in the headset main body 3 incidental vibrations in wearer's body front that earphone cord 3 and clothes friction or lax earphone cord 3 hang on hand and so on.
In addition, here because the binding parts of sound attenuation mechanism 6 can engage or separate, therefore, as shown in Figure 3, be worn on headset main body 1 on the ear after, this sound attenuation mechanism 6 is easy in the neck rear concatenated.
In this sound attenuation mechanism 6, it is not integrated that the 1st binding parts 61 and the 2nd link parts 62, can engage or separated structures but be made into, thus, even the earphone cord 3 of two branch lines part is not a long enough, the earphone wearer also can make this mechanism be configured in the rear of neck under hair style such as is not destroyed even is wearing a hat at state, therefore can obtain good effect.
Also have, the position of Fig. 2 neutral body sound earphone sound attenuation mechanism 6 when being worn is near headset main body 1 side of 3 liang of branch line parts of earphone cord, and the earphone cord 3 between headset main body 1 and the sound attenuation mechanism 6 preferably is in not too lax state.But, as shown in Figure 3, also can be made sound attenuation mechanism 6 be in the roughly position intermediate of 3 liang of branch line parts of earphone cord before wearing at stereophone, if be in this position, make sound attenuation mechanism 6 when the neck rear concatenated, the situation that headset main body 1 that earphone cord 3 is tightened up, worn comes off can take place hardly.
As mentioned above, because the optimum position of sound attenuation mechanism 6, before being disposed at the neck back and the configuration after different, so by making sound attenuation mechanism 6 partly locate and to slide at two branch lines of earphone cord 3, make to become simple, can reduce the inconvenience when neck rear concatenated sound attenuation mechanism 6 in neck rear concatenated sound attenuation mechanism 6.
At this moment, in order to improve the sliding of sound attenuation mechanism 6, preferably, more than the big at least 0.3mm of thickness of diameter than the 1st earphone cord 31 and the 2nd earphone cord 32 of the 1st binding parts 61 of sound attenuation mechanism 6 and the earphone cord through hole of the 2nd binding parts 62.
Also have, shown in Fig. 4 (b), the 2nd linking part 1011 that links parts 101 of sound attenuation mechanism 6 has the convex shape, the 1st linking part 1001 that links parts 100 has O type annular shape, shown in Fig. 4 (a), when sound attenuation mechanism 6 was in connecting state, the 1st links parts became that to link parts with convex the 2nd be can be on the direction of rotation movable structure in center.
Owing to have aforesaid movable mechanism, under the state that neck is bonded later,, also can obtain the effect of headset main body 1 difficult drop-off even headset main body 1 wearer turns round to the left or the right side in sound attenuation mechanism 6.
This be because, as shown in Figure 5, the earphone wearer is during towards the front, the distance of sound attenuation mechanism 6 to left and right sides ear is roughly the same, but as shown in Figure 6, headset main body 1 wearer turns round to the left or during the right side, sound attenuation mechanism 6 changes with the distance of left and right sides ear, it is asymmetric with the distance of left and right sides headset main body 1 left and right sides that also becomes to be sound attenuation mechanism 6, the earphone cord of the side that the distance between sound attenuation mechanism 6 and the headset main body 1 is elongated is pulled to headset main body 1 side, and the earphone cord of opposite side is pulled back to sound attenuation mechanism 6 sides from headset main body 1 side.
When earphone cord 3 passes in and out in the earphone cord through hole of sound attenuation mechanism 6, because the binding parts of sound attenuation mechanism 6 can be movable, so each sound attenuation mechanism 6 can change its position or direction, so that the earphone cord through hole of sound attenuation mechanism 6 turns to the Inbound that of earphone cord 3.
Therefore, when headset main body 1 wearer turns round to the left or during the right side, even earphone cord 3 is pulled to headset main body 1 side, because being the center with the protuberance, the binding parts of sound attenuation mechanism 6 rotate, so earphone cord 3 can successfully be come in and gone out, can reduce because of earphone cord 3 is stuck and cause the appearance of the phenomenon that headset main body 1 comes off from ear.
Next, discuss the optimum length L of the two branch lines part of the earphone cord 3 to 1 of headset main body from earphone cord furcation 4.
Usually, two branch line parts of the earphone cord 3 of stereophone, its length mostly is 35cm～40cm greatly.
But, as the stereophone of present embodiment, when when using earphone, making sound attenuation mechanism 6 in the neck rear concatenated, owing to earphone cord 3 arrives chest from ear through the neck back, so ear to the distance of chest, range difference when arriving chest through the neck back is approximately 10cm, therefore, need be more longer than the two branch lines length partly of general earphone cord, required shortest length is 45cm～50cm.
In addition, for sound attenuation mechanism 6 can be linked in the neck back, at first to pinch the sound attenuation mechanism 6 that is positioned at the health front with finger, it is being delivered in the process of neck back, need crooked two arms to realize sending to sound attenuation mechanism 6, therefore, earphone cord should have near the length that sound attenuation mechanism 6 can be delivered to earphone wearer two shoulder at least.
In general, the male sex about height 170cm, the about 40cm of its shoulder breadth, and, according to the degree of crook difference of arm, sound attenuation mechanism 6 will pass through apart from the place about the about 10cm of shoulder, if count from body centre, one-sided is 30cm, round then be 60cm, but consider because headset main body 1 is worn on the ear, can lacks about 5cm, i.e. the distance from the health center to ear, therefore, the optimum length value is 55cm.
Required shortest length is 45cm, and the optimum length value is 55cm, and 10cm is the optimum length scope before and after the optimum length value, and therefore, the length L of 3 liang of branch line parts of the earphone cord from earphone cord furcation 4 to headset main body 1 is preferably set to:
45cm≤L≤65cm (1)。
In addition, the sound attenuation mechanism 6 of present embodiment preferably uses the elastomeric material of elastomers such as silicones, vinyl chloride resin and so on.
So, when the sound attenuation mechanism 6 that is in connecting state is disposed at the neck back, can alleviate the pain that is pulled to plug 7 sides, produces when sound attenuation mechanism 6 is pressed against on the neck because of earphone cord 3, as bigger strength with earphone cord 3 when plug 7 laybacks are dragged, 6 in sound attenuation mechanism separates automatically, unlikelyly injure neck or force health to reverse, the effect of release mechanism is played by sound attenuation mechanism 6.
