Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and detailed description, this
Utility model proposes a kind of embodiment of earphone, referring to Fig.1 shown in-Fig. 3, including horn hood 100, loudspeaker 200,300 and of ear muff
Auricular concha 400, the horn hood 100 be located in and be formed with earphone back cavity 500, loudspeaker between the auricular concha 400 on the auricular concha 400
200 be fixed on horn hood 100 and be located in the earphone back cavity 500, the ear muff 300 cooperates with the horn hood 100
It is formed with earphone ante-chamber 600, ear muff 300 can be tightened on horn hood 100 by spiral or be fixed by playing screw, in institute
It states and is provided with the first passive radiator 700 on the horn hood 100 that earphone ante-chamber 500 and earphone back cavity 600 are bordered by position, i.e.,
One passive radiator 700 is located on horn hood 100, and the first passive radiator 700 both surrounded earphone ante-chamber with ear muff 300 together
600, while earphone back cavity 500 also is surrounded with auricular concha 400, when the loudspeaker 200 being located in earphone back cavity 500 vibrate, can act on
To the air in earphone back cavity 500, air is acted on, the front and back effect of vibration of air draught to the first passive radiator
On 700, the first passive radiator 700 occurs accordingly to radiation vibration on the inside of earphone back cavity 500 or to outside earphone ante-chamber 600
Side radiation vibration, by the front and back of the first passive radiator 700 vibrate adjustable earphone ante-chamber 600 and earphone back cavity 500 it
Between vibrational state, the vibrational state of earphone ante-chamber 600 and earphone back cavity 500 changed and then influenced whether the vibration of earphone complete machine
Dynamic state, and then realize the adjustment to the vibrational state of complete machine, and then achieve the effect that complete machine acoustical behavior adjusts, reach complete machine
To desired acoustical behavior.
Specifically, can be according to the specification and actual use demand pair of loudspeaker 200 when the first passive radiator 700 is arranged
The earphone that needs are assembled in material, quality, resonance frequency and then the realization that the adjustment answered changes the first passive radiator 700 is whole
Frequency response and sound quality adjustment.Since the first passive radiator 700 has a resonance frequency during fabrication, when loudspeaker 200
For vibration frequency as resonance frequency or when being located at value nearby, entire vibration can be reinforced completely；When 200 vibration frequency of loudspeaker
When in other frequency values, due to there is phase difference between resonance frequency, counteracting may be generated to the vibration of loudspeaker 200, cut
The effect of weak horn vibration, therefore, the first passive radiator 700 in the present embodiment should be set according to the case where specific earphone
Set use.
The second passive radiator 800 is provided on the auricular concha 400.Second passive radiator 800 is mainly used for realizing
Pressure release is carried out to 500 internal pressure of earphone back cavity.Air in earphone back cavity 500, air effect are applied to when loudspeaker 200 vibrate
To the second passive radiator 800, the second passive radiator 800 is vibrated inwardly or outward under air draught effect, is realized
Adjustment to 500 internal pressure of earphone back cavity.
Preferably, the horn hood 100 includes loudspeaker mounting portion 110 and the installation around the setting of loudspeaker mounting portion 110
Position 120, the loudspeaker 200 are assemblied on the loudspeaker mounting portion 110 and seal with the loudspeaker mounting portion 110 and fix, described
First passive radiator 700 is arranged in the installation position 120.
Further, the installation position 120 is annular embedding slot, and first passive radiator 700 is provided with 2, right
Claim setting in the annular embedding slot two sides.Certainly, first passive radiator 700 in the present embodiment also can be set
It is multiple, circumferentially along the annular embedding slot.
Preferably, first passive radiator 700 is arcuation passive radiator, for being adapted to annular embedding slot,
It can be fixed by beating screw or gluing with horn hood 100, second passive radiator 800 is round passive radiator.
Certainly, the first passive radiator 700 and the second passive radiator 800 can also select other shapes of passive radiator, as long as
The function in the present embodiment can be achieved, be not particularly limited herein.
Further, 800 border of the second passive radiator is provided with flange, and second passive radiator 800 is logical
It crosses gluing or screw is fixed on the auricular concha.First passive radiator 700 by gluing or can play screw with flange
It is fixed with horn hood 100.
Further, second passive radiator 800 is arranged at bottom surface or the lateral location of the auricular concha 400.
Second passive radiator 800 may be provided at 400 top surface of auricular concha or lateral location, as long as can be by air pressure
The vibration of corresponding side occurs when contracting.
Headphone structure in the present embodiment substitutes tune by the first passive radiator 700 and the second passive radiator 800
Sound hole, due to being sealing between the first passive radiator 700 and horn hood 100, the second passive radiator 800 and auricular concha 400
Connection, it is ensured that the leakproofness of entire earphone, will not occur that tuning screen cloth falls when carrying out waterproof or salt mist experiment asks
Topic, whole waterproof performance is good, improves the performance of entire earphone.
Meanwhile it can also be improved by changing the first passive radiator 700 and 800 material of the second passive radiator and quality
Entire earphone tone color and acoustic characteristic.
Above embodiments are only to illustrate the technical solution of the utility model, rather than are limited；Although referring to before
Embodiment is stated the utility model is described in detail, it for those of ordinary skill in the art, still can be right
