Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with Drawings and Examples, are further elaborated to this utility model.Should be appreciated that this place is retouched The specific embodiment stated, only in order to explain this utility model, is not used to limit this utility model.

Refer to the semi-open-type earphone that Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 show that this utility model provides The structure of loudspeaker.

This utility model embodiment provides a kind of semi-open-type earphone horn, this semi-open-type earphone loudspeaker Include: support 1, the Magnet 2 being arranged in support 1, be arranged on the washer 3 on described Magnet 2, And the voice coil loudspeaker voice coil 5 being connected with described Magnet 2, the diaphragm 4 being connected with described voice coil loudspeaker voice coil 5；Also include arranging Protecting cover 8 on described support 1, and described protecting cover 8 center has centre bore 81, and described center Hole 81 is more than the size of described voice coil loudspeaker voice coil 5.

In the above-described embodiments, by using the protection cap feature of the band arc of semi-open-type, it is possible to have Effect extension product frequency range and range, earphone horn require loudspeaker high frequency sound, low distortion, full range width, The electroacoustic properties such as clear sound, third dimension are strong.

Understand structure and the principle of the earphone horn that the present embodiment provides for convenience, below in conjunction with tool It is described in detail by the embodiment of body.

As it is shown in figure 1, the present embodiment provide earphone horn include support 1, Magnet 2, washer 3, Diaphragm 4, voice coil loudspeaker voice coil 5, PCB6, Air Filter 7, protecting cover 8, wherein, support 1 as main support, Rely on the circular flat that support 1 provides by diaphragm 4 being bonded in this plane naturally.Magnet 2 For providing fixed magnetic field, make the electric current flowing through voice coil loudspeaker voice coil 5 and Magnet 2 according to the magnetic field intercepts magnetic line of force having Produce active force.Washer 3, in Magnet 2 is according to the space having fixed magnetic field, allows the voice coil loudspeaker voice coil 5 can be more The magnetic field concentrated, and produce bigger active force.Diaphragm 4 directly connects with voice coil loudspeaker voice coil 5, follows voice coil loudspeaker voice coil 5 Vibration, by push or pull air, radiative acoustic wave.Voice coil loudspeaker voice coil 5 is at electric current flowing through voice coil 5 Produce the magnetic field intercepts line of force, be allowed to up-down vibration, PCB6 and voice coil loudspeaker voice coil 5 wire bonding, facilitate audio frequency to pick out. Additionally, the Air Filter 7 arranged is possible to prevent the microgranules such as dust to enter speaker chamber inside and adjustment sound Sound.Protecting cover 8 therein is used for protecting diaphragm 4, and forms ante-chamber, adjusts sound high band.And this protects The protection cap 8 of the band arc of lid 8 employing semi-open-type.It is concrete as in figure 2 it is shown, this protecting cover 8 has One bigger centre bore 81, and the diameter of centre bore 81 is more than the diameter of voice coil loudspeaker voice coil 5, and centre bore 81 with described voice coil loudspeaker voice coil 5 coaxial line.By centre bore 81 it can directly be seen that voice coil loudspeaker voice coil 5.Additionally, at tool When body is arranged, the sidewall of centre bore 81 is provided with two grooves 82.

By the semi-open-type band arc protecting cover 8 arranged, in can guarantee that gamut under the conditions of rated power Keep sound-source signal amplifying power the most clearly.Sound field location standard, directivity is good.And broadcast in music When putting, it is achieved high frequency sound, low distortion, full range width.Understand the earphone that the present embodiment provides for convenience The effect of loudspeaker, with reference to Fig. 3 and Fig. 4, wherein, the earphone horn and 5 that Fig. 3 provides for the present embodiment The Contrast on effect of hole protective cover 8 loudspeaker, earphone horn and 9 holes that Fig. 4 provides for the present embodiment are protected Cover the Contrast on effect of 8 loudspeaker.By the comparing result shown in Fig. 3 and Fig. 4 it can be seen that this enforcement The effect of the earphone horn that example provides to be significantly better than two kinds of earphone horns of the prior art.

By foregoing description it can be seen that the earphone horn of the present embodiment offer is by using semi-open-type Protection cap 8 feature of band arc, it is possible to effectively extension product frequency range and range, earphone horn requirement The electroacoustic properties such as loudspeaker high frequency sound, low distortion, full range width, clear sound, third dimension are strong.

These are only preferred embodiment of the present utility model, not in order to limit this utility model, All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, Within should be included in protection domain of the present utility model.
