Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 shows the structural schematic diagram of the utility model.
Specific embodiment
In order to illustrate more clearly of the utility model, the utility model is done into one below with reference to preferred embodiments and drawings
The explanation of step.Similar component is indicated in attached drawing with identical appended drawing reference.It will be appreciated by those skilled in the art that below
Specifically described content is illustrative and be not restrictive, and should not be limited the protection scope of the present invention.
The utility model provides a kind of earphone, as shown in Figure 1, the earphone includes being with the shell 1 of accommodating chamber and receiving
The phonation unit 2 being dissolved in accommodating chamber.Phonation unit 2 is used to the electric signal of input being converted to voice signal, and phonation unit 2 can
To include magnetic circuit system and vibrational system, vibrational system includes the vibrating diaphragm for sounding.The vibrating diaphragm of phonation unit 2 divides accommodating chamber
It is divided into the preceding operatic tunes 3 and the rear operatic tunes, the preceding operatic tunes 3 is in communication with the outside by going out acoustic aperture 5, so that the voice transmission that phonation unit 2 generates
To the external world.
Specifically, shell 1 includes that the front housing snapped together and rear shell, front housing are positioned adjacent to the vibrating diaphragm of phonation unit 2
Front side, the space formed between front housing and phonation unit 2 be the preceding operatic tunes 3.Rear shell is set on phonation unit 2 far from vibrating diaphragm
Rear side, the space formed between rear shell and phonation unit 2 are the rear operatic tunes.Phonation unit 2 also may include accommodating fixed magnetic circuit system
The shell of system and vibrational system can be equipped with aperture, so that the air-flow on rear side of vibrating diaphragm can pass through aperture and rear sound on shell
Chamber connection.
The earphone of the utility model further includes bassoon 6 and passive vibrating diaphragm 7, and passive vibrating diaphragm 7 is contained in the rear operatic tunes, and will
The operatic tunes is separated into first chamber 4 and second chamber 8 afterwards.One end of bassoon 6 is connected to first chamber 4, the other end and the external world connect
It is logical.When the work of phonation unit 2 makes a sound, the movement of vibrating diaphragm will lead to the air in accommodating chamber and be compressed and be extended, in gas
Under the action of buckling, passive vibrating diaphragm 7 generates vibration, pushes the air of first chamber 4, can thus make a sound and.By
It is arranged in passive vibrating diaphragm 7 at earphone rear portion, in this way, it, which vibrates area, is made bigger than the vibrating diaphragm of phonation unit 2, pushes the body of air
Product is consequently increased, this just greatly improves the amount sense of the bass of earphone.Meanwhile the bore of passive vibrating diaphragm increases, additionally it is possible to drop
Its low resonance dot frequency, enables the earphone of the utility model in sounding, obtains better bass submerged depth.In Hi-Mid portion
Point, since the amplitude of phonation unit itself is smaller, subtle air pressure change is not enough to drive passive vibrating diaphragm 7, and higher vibration
Frequency can also enable passive vibrating diaphragm 7 be difficult to make a response rapidly, and therefore, passive vibrating diaphragm 7 does not have effect to mid-high voice frequency section, be only capable of
Promote the bass effect of earphone.Bassoon 6 can also enhance the bass audio of earphone, further increase the effect of sound quality.
Further, bassoon 6 is contained in inside first chamber 4, and bass pore is offered on the shell at first chamber 4
9, bassoon 6 is in communication with the outside by bass pore 9.Preferably, bassoon 6 is set as bending structure to extend its length,
Promote bass effect.
Shell 1 can be two structures being connected with bassoon 6, and bassoon 6 is the tubular structure extended to two sides.For
Convenient for the assembly of shell 1 and bassoon 6, in the specific embodiment of the utility model, bassoon 6 and shell 1 one
Body formed, in this way, the connection of shell 1 and bassoon 6 is more firm, external form is more aesthetically pleasing.
As shown in Figure 1, bassoon 6 also can be set in the accommodating chamber of shell 1, at this point, bassoon 6 is only to be located to accommodate
Bass chamber in chamber.In this way, bass chamber and the rear operatic tunes are arranged in the accommodating chamber of shell 1.Between bass chamber and first chamber
It can be isolated by plane spaced walls 10, plane spaced walls 10 are convexed to form by the shell inner surface of first chamber 4, this
When, plane spaced walls 10, passive vibrating diaphragm 7 and shell 1 surround bassoon 6 jointly.Preferably, plane spaced walls 10 are set as bending
Structure, so that bassoon 6 is finally the warp architecture with certain length.
Since, without driving mechanism, own can not make a sound, and passive vibrating diaphragm 7 is by sounding list in passive vibrating diaphragm 7
The vibrating diaphragm of body 2 instigates air, and air drives the passive vibration of vibrating diaphragm 7 to make a sound again.The earphone of present embodiment further exists
Sound regulating hole 11 is opened up on the shell of first chamber 4 and second chamber 8 respectively, sound regulating hole 11 being capable of 7 liang of the passive vibrating diaphragm of adjustment
The air pressure of side makes passive vibrating diaphragm 7 be easy to vibration sounding.
The passive vibrating diaphragm 7 of present embodiment includes sequentially connected fixed part, ring portion and central portion from outside to inside, center
Portion surface is combined with reinforcement part.1 inner surface of shell at the operatic tunes convexes to form collar flange 12, the fixation of passive vibrating diaphragm 7 afterwards
Portion is fixedly connected with collar flange.The material of passive vibrating diaphragm 7 can be PET, PU or PEN, and those skilled in the art can be according to reality
Border situation is selected.
Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and
It is not limitations of the embodiments of the present invention, for those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways, all embodiments can not be exhaustive here,
It is all to belong to obvious changes or variations that the technical solution of the utility model is extended out still in the utility model
The column of protection scope.
