Abstract
The invention discloses an in-ear headset, which relates to the technical field of audio equipment and solves the technical problem of improving voice intelligibility. The headset comprises a shell, an earplug, and a loudspeaker as well as a contact microphone respectively mounted in the shell; sound holes are formed on the shell, the inner end of the shell is cylindrical, a slot is arranged in the shell, and the contact microphone is inserted in the slot in a manner of interference; the earplug is composed of a soft ear muff, and a soft inner tube fixed in the ear muff; and the inner end of the shell is inserted in the inner tube of the ear muff in a manner of interference. The in-ear headset is characterized in that the earplug is provided with a soft O-shaped ring, and the inner end of the shell passes through the center of the O-shaped ring. The headset provided by the invention has high voice intelligibility.
Description
Technical field
The present invention relates to audio frequency apparatus technology, particularly relate to a kind of technology of In-Ear headset.
Background technology
In-Ear headset all at casing built with loud speaker and contacting microphone, and sound hole is offered on casing, the sound that loud speaker is sent can conduct in duct, contacting microphone contact be the musculature of people's duct, the vibration of skull and musculature during pickup people's sounding, be converted to the signal of telecommunication, thus realize voice transfer.But because the musculature of duct is very soft, not easily restrain when vibrating, especially low-frequency vibration can cause trembling for a long time of musculature, and the vibration wave therefore in musculature there will be the synergistic effect of similar echo in time domain, cause the muddiness of voice signal, speech intelligibility declines.In addition, because musculature is very soft, comparatively large to dither decay, this is the Another reason that duct contacting microphone speech intelligibility is not high.
Summary of the invention
For the defect existed in above-mentioned prior art, technical problem to be solved by this invention is to provide the high In-Ear headset of a kind of speech intelligibility.
In order to solve the problems of the technologies described above, the In-Ear headset of one provided by the present invention, comprises casing, earplug, and is arranged on loud speaker, the contacting microphone in casing respectively;
Described casing is closed formed by interior half shell, outer half shell joint, casing offers sound hole, makes the sound in casing can conduct to casing outside, the inner of casing is cylindrical, be provided with a slot in casing, contacting microphone is inserted in this slot with interference fit;
Described earplug by soft earcap, and is fixed on the soft interior pipe composition in earcap, and the inner of casing is with in pipe in interference fit insertion earplug;
It is characterized in that: described earplug is equipped with a soft O shape circle, the ring heart of O shape circle is passed in the inner of casing.
Further, described O shape snare is put in earplug on pipe, and with pipe interference fit in earplug.
Further, described O shape circle is one-body molded with the interior pipe of earplug.
Further, described O shape circle is one-body molded with the earcap of earplug.
In-Ear headset provided by the invention, due to the existence of O shape circle, make skull and O shape circle between musculature gap shrinks and compacted, therefore the musculature at this place is not easily trembled naturally, make vibration can Fast Convergent, the dither of skull also can be reduced by decay during this part of musculature, makes the vibration and wave motion importing contacting microphone into be time domain synergistic effect or high frequency attenuation reduces all greatly, thus substantially increases the definition of language.

Fig. 1 is the three-dimensional exploded view of the In-Ear headset of first embodiment of the invention;
Fig. 2 is that the master of the In-Ear headset of first embodiment of the invention looks cut away view;
Fig. 3 is that the master of the In-Ear headset of second embodiment of the invention looks cut away view;
Fig. 4 is that the master of the In-Ear headset of third embodiment of the invention looks cut away view.
Embodiment
Illustrate below in conjunction with accompanying drawing and embodiments of the invention are described in further detail; but the present embodiment is not limited to the present invention; every employing analog structure of the present invention and similar change thereof, all should list protection scope of the present invention in, the pause mark in the present invention all represent and relation.
As Figure 1-Figure 2, the In-Ear headset of the one that first embodiment of the invention provides, comprises casing, earplug, and is arranged on loud speaker 2, the contacting microphone 3 in casing respectively;
Described casing is engaged formed by interior half shell 12, outer half shell 11, casing offers sound hole 13, make the sound in casing can conduct to casing outside, in cylindrical, (in ear, one end is inner in the inner 121 of casing, outside ear, one end is outer end), be provided with a slot in casing, contacting microphone 3 is inserted in this slot with interference fit;
Described earplug is by soft earcap 42, and the soft interior pipe 41 be fixed in earcap 42 forms, and the inner 121 of casing is with in pipe 41 in interference fit insertion earplug;
It is characterized in that: the interior pipe 41 of described earplug is equipped with a soft O shape circle 5, interior pipe 41 interference fit of this O shape circle 5 and earplug, the ring heart of 5 is enclosed in the inner 121 of casing through O shape, due to O shape circle and pipe interference fit in earplug, not easily move relative to earplug, there is higher reliability.
When first embodiment of the invention uses, duct is inserted in the inner of casing, the output sound of loud speaker is input in duct by the sound hole on casing, after duct is inserted in casing the inner, the earcap of earplug is adjacent to ear canal wall musculature 6, due to the existence of O shape circle, the position that duct musculature 6 is enclosed O shape is compressed, make skull 7 and O shape circle 5 between musculature gap shrinks and compacted, therefore musculature is just not easily trembled naturally, make vibration can Fast Convergent, simultaneously because musculature is compacted, the dither of skull also can be reduced by decay during this part of musculature, therefore the vibration and wave motion importing contacting microphone into is time domain synergistic effect or high frequency attenuation reduces all greatly, thus substantially increase the definition of language, because O shape circle is for circular and be soft body, also foreign sense when user wears, and casing the inner random rotational angle in duct also can not cause the change of voice quality, very easy to use.
As shown in Figure 3, the difference of second embodiment of the invention and the first embodiment is: the O shape in the second embodiment is enclosed 205 one-body molded with the interior pipe 241 of earplug, second embodiment of the invention is one-body molded owing to managing in O shape circle and earplug, can not move relative to earplug, relative first embodiment has higher reliability.
As shown in Figure 4, the difference of third embodiment of the invention and the first embodiment is: the O shape in the 3rd embodiment is enclosed 305 one-body molded with the earcap 342 of earplug, third embodiment of the invention due to O shape circle one-body molded with the earcap of earplug, can not move relative to earplug, relative first embodiment has higher reliability.
