Detailed Description

The utility model provides a headset bluetooth noise reduction earphone, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that following combination embodiment the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 10, the present invention provides a bluetooth headset with noise reduction function. For ease of viewing, the ear loops are not shown in fig. 3.

The head-wearing Bluetooth noise reduction earphone comprises a head hoop 11 and two support arms 12, wherein each support arm 12 is connected with a sound production unit 4, and a telescopic mechanism 2 is connected between each support arm 12 and the head hoop 11, so that the head hoop and the support arms can be stretched; each support arm is connected with a rotating part 3; each generating unit is respectively provided with a bracket 5, and each bracket is respectively and rotatably connected with the rotating part at the same side; each generating unit 4 comprises an ear shell 40, a concave cavity 41 is arranged in each ear shell, a horn 42 is arranged in each concave cavity, and a horn cover 43 is arranged in each concave cavity; as shown in fig. 4 and 5, one of the sound generating units is provided with a circuit board 491, and the other generating unit is provided with a Bluetooth plate 482. As can be seen from fig. 2 and 5, the outer side of each bracket is provided with a bracket cover 50. As can be observed from fig. 7, each rotor is correspondingly provided with a rotor cover 39 to facilitate assembly and spacing of the rotors. In practical application, the loudspeaker and the Bluetooth board are respectively electrically connected with the circuit board. Since the circuit board, the bluetooth board, and the speaker themselves are prior art, they are not particularly limited herein.

It can be observed from the figures that each cavity 41 is of a semi-enclosed construction, with its opening facing inwards, i.e. in actual use, the opening of the cavity facing towards the user's ear. Because the periphery and the surface of the concave cavity are not provided with the through holes, the sound emitted by the horn can only be transmitted out from the through hole in the middle of the horn cover, thereby being beneficial to improving the tone quality and reducing the noise.

As shown in fig. 9, further, a plurality of through holes are provided in the middle of each horn cover 43, and a feedforward noise reduction microphone 451 is provided in the middle of each horn cover; the rear side of each cavity is respectively provided with a feedback noise reduction microphone (not observed from the view angle of fig. 9); the effect of eliminating external noise is further improved by arranging the feedforward noise reduction microphone and the feedback noise reduction microphone.

That is, in actual use, each rotating member may rotate up and down with respect to the head band bottom end, and each generating unit may rotate with respect to the axis of the circular boss of the corresponding rotating member, so that it may be folded into a state as shown in fig. 2, such that the thickness direction of the sound generating unit coincides with the width direction of the head band, and compared to the prior art, the volume after folding is further reduced.

Furthermore, the bottom of the two ends of the head band 1 is provided with a notch 101 corresponding to the rotating member, so that the rotating member does not interfere with the head band when rotating upward.

Further, the depth of each cavity is larger than the thickness of the horn, so that the horn is convenient to mount.

As shown in fig. 4, further, a bluetooth indicator lamp (484) is disposed in a generating unit of the bluetooth headset, so as to observe the bluetooth connection status of the headset during use.

As shown in fig. 4, in particular, the head band 11 includes a head bow 11 and a head band sheath 13, between which a silicone fastener 12 is disposed. This arrangement facilitates assembly of the head band and improves comfort when worn. In practical application, two ends of the head bow can be respectively connected with corresponding telescopic mechanisms through pins.

Referring to fig. 4 and 7, each arm 12 includes an upper arm cover 121 and a lower arm cover 122, and the inner side of each upper arm cover is provided with an adjusting tooth 1211; each telescoping mechanism 2 comprises a stretching cover 21, a stretching strip 22 and an elastic sheet 23. During the actual use, every shell fragment can be respectively with the regulation tooth of that support arm upper cover that corresponds joint step by step to realize flexible purpose.

Furthermore, it can be seen from fig. 2, 4 and 5 that one ear cap 60 is provided on the inside of each generating unit. As shown in fig. 5, a battery 481, a noise reduction indicator lamp 492, and a noise reduction switch 493 for switching the function of the noise reduction switch are also provided in the generation unit provided with the circuit board. As can be observed from fig. 4, the ear shell of the generation unit provided with the bluetooth plate is provided with an operation key 483.

According to the above analysis, the utility model provides a headset of making an uproar falls in bluetooth, through setting up the rotation piece, the support, every support is rotationally connected with that rotation piece of homonymy respectively to when realizing that the earphone is folding, the thickness direction that can realize sound producing unit is unanimous with the width direction of head hoop, reduces the volume after the earphone is folded by a wide margin. In addition, through setting up parts such as cavity, horn cover for the earphone has the better function of making an uproar of falling when using, has improved tone quality.

It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
