Abstract
The utility model relates to an in-ear earphone horn which is characterized in that the in-ear earphone horn mainly comprises a voice diaphragm, a front cover and a U-shaped cup. The voice diaphragm and the front cover form a front cavity; the voice diaphragm and the U-shaped cup from a first-stage back cavity; and the outer side of the front cover is provided with a front sound pipe. The in-ear earphone horn is simple in structure, convenient to use and high in practicality. By changing the structure of the original in-ear earphone horn, that is, adding the front sound pipe in front of the horn, the front sound pipe capable of toning is formed, so that tone tuning can be carried out by changing the diameter, the length or the material of the front sound pipe, and the tone tuning can also be carried out by changing the sound absorption effect of tone tuning cloth on the front sound pipe. Sound sent from the horn can adjust mid-high frequency band of a frequency response curve after passing through the front sound pipe and the earphone front cavity, thereby reducing the influence of earphone housing second-stage back cavities of various shapes on the key frequency band tuning of the horn, enabling the final frequency response curve of the earphone to have relatively-high consistency with the horn, and facilitating the whole earphone tuning design.
Description
Technical field
The utility model belongs to earphone horn technical field, specifically relates to a kind of In-Ear Headphones loudspeaker.
Background technology
In earphone production process, tuning is most important link.Sound film and protecgulum form ante-chamber, sound film and U cup-shaped become one-level back cavity, U cup and ear casing inner chamber formation secondary back cavity.Loudspeaker are phonation units of earphone, and ear casing back cavity (being one-level back cavity and secondary back cavity) affects the sound field of loudspeaker, directly changes the sound effect that ear is experienced.At present, earphone tuning need to have been debugged roughly loudspeaker frequency response curve, loads onto debugging repeatedly again after earphone, the uncertain impact producing to eliminate ear casing back cavity.In a lot of situations, ear casing back cavity is very large on the impact of loudspeaker sound field, to such an extent as to vetos the design of whole earphone tuning.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of In-Ear Headphones loudspeaker, and it can weaken the impact of ear casing back cavity on tuning, makes the higher consistency that has of the final frequency response curve of earphone and loudspeaker, thereby is conducive to the design of whole earphone tuning.
In order to achieve the above object, a kind of In-Ear Headphones loudspeaker of the utility model, mainly comprise sound film, protecgulum, U cup, the ante-chamber of sound film and protecgulum formation, and sound film and U cup-shaped become one-level back cavity; The outside of described protecgulum is provided with a front sound pipe for tuning, and this front sound pipe can weaken the impact of ear casing back cavity on tuning.In practical application loudspeaker, also has ear casing in the outside of loudspeaker, the secondary back cavity that U cup and ear casing inwall form.Experiment shows, can carry out tuning by the diameter, length or the material that change front sound pipe, the sound that loudspeaker send is after front sound pipe and earphone ante-chamber, the impact of the ear casing back cavity that can reduce to a great extent various shapes on loudspeaker sound field, makes the higher consistency that has of the final frequency response curve of earphone and loudspeaker.
Preferably, described front sound pipe is provided with tuning cloth, and this tuning is laid on the port of one end of front sound pipe.
Preferably, between described protecgulum and U cup, be provided with a copper ring.
Preferably, described sound film is provided with a voice coil loudspeaker voice coil.
Preferably, described U cup is provided with a tuning cloth.
Preferably, between described U cup and sound film, be provided with a washer.
Preferably, between described U cup and washer, be provided with magnet steel.
Preferably, the lower end, outside of described U cup is provided with terminal block.
The utility model is simple in structure, easy to use, practical.It is by changing the structure of original In-Ear Headphones loudspeaker, before loudspeaker, add the sound pipe of going forward, formation can tuning front sound pipe, so just, can be by the diameter of sound pipe before changing, length or material are carried out tuning, also can carry out tuning by the acoustically effective that changes the tuning cloth on front sound pipe, the sound that loudspeaker send is after front sound pipe and earphone ante-chamber, can regulate the medium-high frequency section of frequency response curve, the impact of the secondary back cavity of ear casing that reduces to a great extent various shapes on the crucial frequency range tuning of loudspeaker, make the higher consistency that has of the final frequency response curve of earphone and loudspeaker, thereby be conducive to the design of whole earphone tuning.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is sound film, and 2 is protecgulum, and 3 is U cup, and 4 is ante-chamber, and 5 is one-level back cavity, and 6 is front sound pipe, and 7 is copper ring, and 8 is voice coil loudspeaker voice coil, and 9,13 is tuning cloth, and 10 is washer, and 11 is magnet steel, and 12 is terminal block.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, but not as to restriction of the present utility model.
With reference to Fig. 1, as can be seen from Figure 1, a kind of In-Ear Headphones loudspeaker of the utility model embodiment, mainly comprise sound film 1, protecgulum 2, U cup 3, the ante-chamber 4 that sound film 1 and protecgulum 2 form, and the one-level back cavity 5 that forms of sound film 1 and U cup 3; The outside of described protecgulum 2 is provided with the front sound pipe 6 for tuning, and this front sound pipe 6 can weaken the impact of ear casing back cavity on tuning.In practical application loudspeaker, also has ear casing in the outside of loudspeaker, the secondary back cavity that U cup 3 and ear casing inwall form.Experiment shows, can carry out tuning by the diameter, length or the material that change front sound pipe 6, the sound that loudspeaker send is after front sound pipe 6 and earphone ante-chamber 4, the impact of the ear casing back cavity that can reduce to a great extent various shapes on loudspeaker sound field, makes the higher consistency that has of the final frequency response curve of earphone and loudspeaker.
With reference to Fig. 1, described front sound pipe 6 is provided with tuning cloth 13, and this tuning cloth 13 is located on the port of one end of front sound pipe 6.Between described protecgulum 2 and U cup 3, be provided with a copper ring 7, sound film 1 is provided with a voice coil loudspeaker voice coil 8, is provided with a tuning cloth 9 on U cup 3.Between described U cup 3 and sound film 1, be provided with a washer 10, and between U cup 3 and washer 10, be provided with magnet steel 11, be provided with terminal block 12 in the lower end, outside of U cup 3, the lower end of terminal block 12 is also provided with tuning cloth.
This is simple in structure, easy to use, practical.It is by changing the structure of original In-Ear Headphones loudspeaker, before loudspeaker, add the sound pipe 6 of going forward, formation can tuning front sound pipe 6, so just, can be by the diameter of sound pipe 6 before changing, length or material are carried out tuning, also can carry out tuning by the acoustically effective that changes the tuning cloth 13 on front sound pipe 6, the sound that loudspeaker send is after front sound 6 pipes and earphone ante-chamber 4, can regulate the medium-high frequency section of frequency response curve, the impact of the secondary back cavity of ear casing that reduces to a great extent various shapes on the crucial frequency range tuning of loudspeaker, make the higher consistency that has of the final frequency response curve of earphone and loudspeaker, thereby be conducive to the design of whole earphone tuning.
Below the utility model is described in detail, but apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from the scope of the present utility model that appended claims limits.
