The utility model provides a kind of earphone, with reference to Fig. 1, and the earphone includes being with the shell 1 of receiving space and set
The phonation unit 2 being placed in the receiving space.The phonation unit 2 is used to the sound electric signal of input being converted to sound letter
Number.The phonation unit 2 can include magnetic circuit system and vibrational system, and the vibrational system includes the vibrating diaphragm for sounding.Institute
The receiving space is divided into the preceding operatic tunes 3 and the rear operatic tunes 5 by the vibrating diaphragm for stating phonation unit 2, and the preceding operatic tunes 3 is by going out acoustic aperture 4
It is in communication with the outside, so that the transfer voice that the phonation unit 2 is produced is to the external world.
Specifically, the shell 1 can include the protecgulum and rear shell matched, and the protecgulum is positioned adjacent to the sounding
The front side of the vibrating diaphragm of unit 2, the space formed between the protecgulum and the phonation unit 2 is the preceding operatic tunes 3；The rear shell
It is arranged at the rear side away from the vibrating diaphragm, the space formed between the bonnet and the phonation unit 2 on the phonation unit 2
For the rear operatic tunes 5.The phonation unit 2 can also include housing the fixed magnetic circuit system and the shell monomer of vibrational system
Body, can be provided with perforate, to allow the air-flow on rear side of the vibrating diaphragm to pass through the perforate and institute on the monomer shell 1
The rear operatic tunes 5 is stated to connect.
With reference to Fig. 1, the earphone also includes bassoon 7, and the bassoon 7 is connected with the rear operatic tunes 5.The bassoon
7 one end is connected with the rear operatic tunes 5.The other end away from the rear operatic tunes 5 can be let out by described on the bassoon 7
Acoustic aperture is directly in communication with the outside.
Sound-absorbing material 8 is filled with the bassoon 7.The sound-absorbing material 8 is used to absorb the incoming sound thereafter of earphone diaphragm
Medium-high frequency sound wave in chamber 5.For example, the sound-absorbing material 8 can be by flexible material, perforated plate of resonant interaction sound absorption etc.,
To absorb intermediate frequency sound wave；The sound-absorbing material 8 can also be various organic or inorganic fibers with fibril aggregation tissue and its
Open cell foam and expanded perlite product of product and loose structure etc., to absorb intermediate frequency sound wave.Above material can
To be used alone, can also compound use to expand sound absorption frequency range.
Preferably, the sound-absorbing material 8 includes sound-absorbing porous material.Have inside the sound-absorbing porous material some superfine
Pipeline, the superfine pipeline is considered as capillary.The vibration that sound wave is produced can cause the windage in capillary, and with
The inwall of capillary produces heat transfer so that acoustic energy is converted to heat energy and consumed；Because medium, high frequency sound wave can cause capillary
The vibration velocity of inner air tube is accelerated, and the heat exchange of air and capillary wall is also accelerated so that the sound-absorbing porous material can be right
Medium, high frequency sound wave has good absorption.
Further, the sound-absorbing porous material is zeolitic material.Such as described sound-absorbing material 8 can be only by zeolitic material
Composition.Zeolitic material is with low cost, and its inner porosity may be regarded as superfine pipeline, is filled in after the bassoon 7, according to
Propagation characteristic of the sound in capillary, it can improve low frequency tonequality.
Therefore, after the lumen loading sound-absorbing material 8 of the bassoon 7, equivalent acoustic mass increase, so as to improve earphone
Low frequency tonequality.It so, it is possible in the case where the actual volume of the inner chamber of bassoon 7 need not be increased, improve earphone
Low frequency tonequality.
It should be noted that the utility model is not limited specifically the classification of earphone, the earphone can be
Half not enough In-Ear Headphones of low frequency performance or Supra-aural headphone etc..In this way, half In-Ear Headphones or ear-sticking ear
The low frequency performance of machine etc. can be improved.
It is described in an embodiment of the present utility model for the ease of the assembling and fixation of sound-absorbing material 8
The inner surface of sound-absorbing material 8 and the bassoon 7 bonds together.Specifically, the sound-absorbing material 8 can by glue or
The emplastics such as double faced adhesive tape are bonded in the inner surface of the bassoon 7.So so that sound-absorbing material 8 is stably assembled, is fixed on
On the inner surface of the bassoon 7.
With reference to Fig. 1, the shell 1 and the bassoon 7 can be two structures being connected, the bassoon 7 be to
The tubular structure of both sides extension.For the ease of the assembling of the shell 1 and the bassoon 7, in one of the present utility model tool
In body embodiment, the bassoon 7 is integrally formed with the shell 1.In this way, the connection of the shell 1 and the bassoon 7
More firm, appearance is more aesthetically pleasing.
It should be noted that the bassoon 7 can also be arranged in the receiving space of shell 1.Now, the bass
Pipe 7 is actually only the bass chamber being located in the receiving space.In this way, the bass chamber and the rear operatic tunes 5 are arranged at
In the receiving space of the shell 1.The bass chamber can be isolated with the rear operatic tunes 5 by plane spaced walls, described
Some through holes are provided with plane spaced walls.The bass chamber can isolate to be formed by least one bending spaced walls, so
The bass chamber is in finally the warp architecture with certain length.
With reference to Fig. 1, the earphone in the utility model also includes the audio signal wire 6 being connected with the phonation unit 2, to carry
The phonation unit 2 is supplied with sound electric signal.In an embodiment of the present utility model, the audio signal wire
6 after described the operatic tunes 5, the bassoon 7 draw.
The vibration of sound wave can drive the vibration of the audio signal wire 6, in order to avoid the audio signal wire 6 with it is described low
The inwall of sound tube 7 produces friction, it is preferable that the sound-absorbing material 8 is evenly distributed in around the audio signal wire 6.Such as
This, it is to avoid the audio signal wire 6 close to or away from the bassoon 7 any side inner surface.
In order that obtaining the sound-absorbing porous material has preferably acoustically effective, more preferably low frequency tonequality is obtained, it is preferable that
The sound-absorbing material 8 can be filled between the bassoon 7 and the audio signal wire 6, such as outside described sound-absorbing material 8
Surface can fit in the audio signal wire 6, and the inner surface of the sound-absorbing material 8 can fit in the interior of the bassoon 7
Surface.
In order to avoid the audio signal wire 6 produces relative motion so as to produce with the sound-absorbing material 8 in the bassoon 7
Friction, it is preferable that the inner surface of the sound-absorbing material 8 and the bassoon 7 bonds together, the sound-absorbing material 8 can be with
The audio signal wire 6 bonds together, for example, bonded together by way of glue or double faced adhesive tape.
The utility model additionally provides a kind of audio-visual equipment, the audio-visual equipment can with but be not limited to mobile phone, computer, MP3,
MP4, intelligent watch, radio, television set, wear display device etc..The audio-visual equipment includes above-mentioned earphone.The audio-visual equipment has
Standby outstanding low frequency tonequality.
The preceding and orientation term such as rear mentioned in this manual is defined relative to the construction shown in each accompanying drawing
, they are relative concepts, and it is therefore possible to can correspondingly be become according to its residing diverse location, different use states
Change.So, these or other orientation term should not be construed to restricted term.
