Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1, fig. 2 and fig. 3 in combination, wherein fig. 1 is a schematic structural diagram of a preferred embodiment of the novel wind noise prevention earphone structure provided by the present invention; FIG. 2 is a schematic cross-sectional view of the upper cover shown in FIG. 1; fig. 3 is an exploded view of the present invention.

Novel prevent wind and make an uproar earphone structure includes hollow mesochite 1 and upper cover 2, and mesochite 1 assembles into an earphone head structure with upper cover 2.

The rear part of the middle shell 1 is provided with a rear cover to form a complete earphone shell structure.

The inside fixed mounting of upper cover 2 has PCBA board 5, the last through-hole 6 of having seted up of PCBA board 5, set up the straight pickup hole 3 along the lateral wall of mesochite 1 internal extension on the front of mesochite 1, the inner of directly picking up sound hole 3 corresponds the intercommunication with through-hole 6, be provided with between the inner of straight pickup hole 3 and the through-hole 6 and prevent wind screen cloth 7, the side opening 4 with the intercommunication of straight pickup hole 3 is seted up to the side of mesochite 1, the fixed position that the bottom of PCBA board 5 and through-hole 6 correspond has miaow head 9.

The microphone 9 is a term of art, namely a microphone or a sound pick-up.

Directly pick up and form between 3 outer ends of sound hole and the side opening 4 and be greater than 90 contained angles, form approximate T font structure, when the user speaks, through directly picking up sound hole 3 and side opening 4 radio reception simultaneously, through the inner of directly picking up sound hole 3 to 2 inside transmissions of upper cover, transmit to miaow head 9 through-hole 6, carry out signal conversion after carrying out the pickup by miaow head 9, convert sound signal into the signal of telecommunication, and transmit through the wire of earphone, concrete transmission mode is prior art, and not the utility model discloses the technical scheme who protects, do not redundantly here, other current parts such as loudspeaker still can be installed to earphone casing inside simultaneously, also not the utility model discloses the technical scheme who protects, do not do here to describe repeatedly.

Under windy or the air current condition, because straight pick-up hole 3 outwards, the air current mainly flows in from the outer end of straight pick-up hole 3, after the inside of getting into straight pick-up hole 3, the in-process of inward flow, and a part air current can be followed side opening 4 and directly flowed out, plays the effect that reduces wind and make an uproar, and remaining part air current continues inward flow, is prevented wind the further separation of screen cloth 7 by preventing wind, further reduces wind and makes an uproar, and the two mutual structure, the at utmost reduces wind and makes an uproar.

Through adopting directly to pick up sound hole 3 and side opening 4 complex mode, still adopt linear type pickup passageway, do not prolong pickup passageway, the problem that heterotypic pickup passageway leads to sound attenuation like L type or U type are buckled has also been avoidd, guarantee the volume of pickup, windy or the air current is great, the air current can be followed side opening 4 and flowed out partly, form the wind channel of letting out, another part is prevented wind the screen cloth separation, the at utmost reduces the wind and makes an uproar, the diplopore structure makes under the condition that can obtain great pickup volume, can furthest reduce the wind and make an uproar, it influences speech quality to avoid the wind to make an uproar to disturb the pickup, simultaneously, the structure is comparatively simple, it is more convenient to process.

The top of the PCBA board 5 and the outer ring of the through hole 6 are fixedly provided with a sealing ring 8, and when the PCBA board 5 is fixedly arranged in the inner cavity of the upper cover 2, the sealing ring 8 tightly supports the windproof screen cloth 7 to the inner end of the straight pickup hole 3.

Sealing washer 8 is the silica gel material, through sticky fixed mounting to 5 surfaces of PCBA board, prevent wind screen cloth 7 through sticky fixed mounting in 8 tops of sealing washer.

PCBA board 5 is the rigid plastic material, and prevent wind being connected between the screen cloth 7 probably inseparable inadequately, through setting up elastic sealing washer, can be so that PCBA board 5 can not have the gas leakage point with prevent wind screen cloth 7, guarantees that the air current can be filtered by prevent wind screen cloth 7, can support tightly in the bottom of straight pickup hole 3 simultaneously with preventing wind screen cloth 7, guarantees the gas tightness, reduces wind and makes an uproar.

A plurality of mounting holes are perforated on the PCBA board 5. The inside erection column that is provided with of upper cover 2, the inside screw hole that is provided with of erection column can be through inside PCBA board 5 fixed mounting to upper cover 2 with the screw.

The middle shell 1 and the upper cover 2 are assembled into a whole through clamping. The connection and fixation can also be realized by gluing and the like.

The cross section of the side wall of the upper cover 2 is step-shaped, and the inner cavity of the upper cover 2 forms a mounting position for mounting the PCBA board 5. The lateral surface of the lateral wall of the upper cover 2 is an outward convex step, the medial surface is an inward concave step, and the PCBA board 5 is fixedly installed on the inward concave step.

The utility model provides a novel prevent wind noise earphone structure's theory of operation as follows:

when a user speaks, the user can simultaneously receive sounds through the straight sound pickup hole 3 and the side hole 4, the inner end of the straight sound pickup hole 3 is transmitted to the inner part of the upper cover 2 and is transmitted to the microphone 9 through the through hole 6, the microphone 9 picks up the sounds and converts the sounds into electric signals.

The above-mentioned only be the embodiment of the present invention, not consequently the restriction of the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transform made of the content of the specification and the attached drawings, or directly or indirectly use in other relevant technical fields, all including in the same way the patent protection scope of the present invention.
