Embodiment
Below in conjunction with drawings and embodiments, the utility model is described further.
Embodiment
As Figure 1-4, the earphone microphone shell of sound passage led by a kind of band, comprises miaow upper casing 1, substrate 2, foam cotton 3, leads sound internals 4, miaow lower casing 5, sheath 6 and wire 7; Wherein,
The sidewall of described miaow lower casing 5 is provided with catch 12, and catch 12 is also provided with continuant orifice 13, and the periphery, one end of wire 7 is set with sheath 6, and sheath 6 mates with the sheath location notch 14 on miaow upper casing 1, miaow lower casing 5; Wire is avoided to pull apart because of pullling stressed;
On described substrate 2, paster is provided with silicon wheat 8 and forms board unit; Described silicon wheat 8 is connected with the through hole 9 of leading in sound internals 4 and mates;
Described sound internals 4 of leading are arranged on miaow lower casing inside, described sound internals 4 of leading are for L shape, its lateral wall is provided with the L shape identical with leading sound internals 4 shape and leads sound channel groove 10, be provided with in the bottom of leading sound internals and the through hole 9 of leading sound channel groove and being connected, described L shape is led sound channel groove 10 and is mated with continuant orifice 13;
The bottom of described substrate 2 is provided with the foam cotton 3 of two-sided back of the body 3M glue, is fixed on leads in sound internals 4 by the foam cotton 3 of two-sided back of the body 3M glue; Be assembled in miaow lower casing 5 by above-mentioned sound internals 4 of leading again, miaow lower casing 5 devises and the location notch of leading sound internals 4 and matching, and makes it to locate completely each other, then by being fixed at the lateral wall glue coating of leading sound internals 4 and being sealed in location notch.
Substrate 2 is assembled in the above miaow lower casing 5 assembled, and because foam cotton 3 has the two-sided 3M gummed paper of the back of the body, reaches the effect that sound internals are led in sealing.
The point that the two ends of miaow lower casing 5 and miaow upper casing 1 are designed with coupling breaks formula ultrasound lines 11, and during ultrasonic operation, ultrasonic device is pushed down miaow upper casing 1 and driven miaow upper casing 1 and miaow lower casing 5 to rub and produces heat, and heat melts ultrasound lines 11 and completes welding effect.
Be reserved with catch 12 outside miaow lower casing 5, make to form gap when miaow lower casing 5 and miaow upper casing 1 ultrasonic welding, external sound enters the L shape of leading sound internals 5 through gap by continuant orifice 13 and leads sound path 10, is picked up by silicon wheat 2.Earphone microphone shell of the present utility model employs plate mo(u)ld bottom half silicon wheat 8 cleverly, and therefore miaow shell volume can design less.
comparative example
A kind of miaow shell structure using electret microphone, as shown in Figure 5, sound is entered by the pickup hole of miaow lower casing 5 ', filtered by Air Filter 16, by electret microphone 15 pickoff signals of paster on substrate 2 ', miaow lower casing 5 ' carries out welding by ultrasonic equipment and miaow upper casing 1 ', because miaow lower casing 5 ' pickup hole is directly just to electret microphone 15, because of consume individual use earphone time, hold the call of miaow shell from face too close to and often produce spray wheat phenomenon, thus affect the speech quality of earphone.If just not right, affect again miaow shell overall sensitivity.
The utility model leads sound internals 4 by employing in the additional design in miaow shell inside, lead and sound internals 4 are designed with L shape lead sound path 10, thus mouth is spoken and is formed 90 degree of vertical angles with silicon wheat 8 hole when achieving call, sound forms stable acoustic pressure after leading sound passage and entering silicon wheat, eliminate and directly just conversed the spray wheat phenomenon caused in aperture, enhance earphone speech quality.
