Description
Technical field
The utility model belongs to technical field of acoustics, specifically refers to a kind of head-mounted noise reduction earphone.
Background technique
With the development of society and the progress of science and technology, acoustic technique development is swift and violent, and earphone products application also comes wider
It is general, especially headphone.
Currently, existing some headphone products are not reasonable since structure designs, noise reduction effect is poor, seriously affects
Acoustical quality has been unable to meet consumer demand.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of designs more rationally, the better wear-type of noise reduction effect
Noise cancelling headphone.
In order to solve the above technical problems, the utility model uses following technical scheme:
A kind of head-mounted noise reduction earphone, including auricular concha ontology, microphone and loudspeaker, auricular concha ontology include auricular concha pedestal and
The auricular concha cover connecting with auricular concha pedestal, is equipped with control circuit board in auricular concha pedestal, microphone and loudspeaker respectively with control
Circuit board connection processed, is equipped with noise reduction module in control circuit board, and auricular concha cover upper side top is recessed toward auricular concha pedestal direction,
Loudspeaker is installed on the inner bottom surface of auricular concha cover upper side, and loudspeaker and auricular concha cover upper side are in parastate；Microphone
It is installed in the recess side wall on auricular concha cover upper side top, microphone and loudspeaker are in vertical state.
Preferably, it is equipped with mounting groove in the recess side wall on auricular concha cover upper side top, microphone is installed on mounting groove
It is interior.
Preferably, above-mentioned loudspeaker is to snap connection or be threadedly coupled with auricular concha cover.
Preferably, above-mentioned auricular concha pedestal and auricular concha cover are to snap connection or be threadedly coupled.
The utility model has following remarkable result:
The utility model head-mounted noise reduction earphone is reasonable in design, by setting past for auricular concha cover upper side top
Auricular concha pedestal direction is recessed, and microphone is installed in the side wall of recess, and by the installation position of microphone and loudspeaker
The absorption for greatly facilitating microphone to be mutually perpendicular to noise is installed, denoising is carried out to noise in time, it is also significantly advantageous
De-noising sound wave is discharged in loudspeaker, to realize the effect for promoting noise reduction, greatly improves earphone output sound timbre.
Detailed description of the invention
Attached drawing 1 is the utility model schematic view of the front view；
Attached drawing 2 is the utility model auricular concha ontology side structure schematic view；
Attached drawing 3 is the utility model auricular concha body interior structural schematic diagram.
Accompanying drawings symbol description:
1 auricular concha ontology, 11 auricular concha pedestal, 12 auricular concha cover, 120 121 mounting groove of auricular concha cover upper side, 2 microphone 3
4 control circuit board 41 of loudspeaker keeps away a hole.
Specific embodiment
In order to facilitate the understanding of those skilled in the art, below in conjunction with attached drawing and embodiment to the utility model carry out into
One step detailed description.
As shown in attached drawing 1~3, a kind of head-mounted noise reduction earphone, including auricular concha ontology 1, microphone 2 and loudspeaker 3, auricular concha
Ontology 1 includes auricular concha pedestal 11 and auricular concha cover 12, and auricular concha pedestal 11 and auricular concha cover 12 are to snap connection or be threadedly coupled, side
Just it disassembles and installs；Control circuit board 4 is installed in auricular concha pedestal 11, microphone 2 and loudspeaker 3 respectively with control circuit board
4 connections, are equipped with noise reduction module in control circuit board 4.When consumer uses earphone, after microphone 2 receives ambient noise, then
Noise warning signal is reached to the control circuit of control circuit board 4, noise reduction module carries out real-time operation, plays and makes an uproar by loudspeaker 3
The identical sound wave of sound opposite in phase, amplitude offsets noise, carries out de-noising, to improve the acoustical quality of the output of loudspeaker 3.
In the present embodiment, recessed toward 11 direction of auricular concha pedestal on 120 top of auricular concha cover upper side, loudspeaker 3 is installed on
On the inner bottom surface of auricular concha cover upper side 120, loudspeaker 3, also to snap connection or being threadedly coupled, is conveniently torn open with auricular concha cover 12
It unloads and installs, here, loudspeaker 3 and auricular concha cover upper side 120 are in parastate, i.e. loudspeaker 3 and auricular concha cover upper side
120 installation site is parallel to each other, as shown in Fig. 3；It is set in the recess side wall on 120 top of auricular concha cover upper side
Have mounting groove 121, microphone 2 is then installed in mounting groove 121, microphone 2 and loudspeaker 3 in vertical state, i.e. 2 He of microphone
The installation site of loudspeaker 3 be it is orthogonal, as shown in Fig. 3.
The present embodiment is equipped in control circuit board 4 and keeps away a hole 41, and the corner of 3 top bottom surface of loudspeaker, which extends, keeps away position
In hole 41, to save the installation space inside auricular concha ontology 1, space utilization rate is improved.
Auricular concha cover upper side top is set as being recessed toward 11 direction of auricular concha pedestal by the present embodiment, and microphone is installed
It is set as being mutually perpendicular in the side wall of recess, and by the installation site of microphone 2 and loudspeaker 3, greatly facilitates Mike
Absorption of the wind 2 to noise carries out denoising to noise in time, also greatly facilitates loudspeaker 3 and de-noising sound wave is discharged, thus
It realizes the effect for promoting noise reduction, greatly improves earphone output sound timbre.
Above-described embodiment is preferred embodiment of the utility model, and non-limiting exhaustion, this reality under same idea
There can also be other variations with novel.It should be noted that appointing under the premise of not departing from the present utility model design
What obvious replacement is within scope of protection of the utility model.
