Abstract

The utility model relates to a kind of 5 conduit 5 unit combination and moves iron earphone, and comprise 5 independently metal sound-guiding tube and corresponding dynamic iron unit, be positioned at middle metal sound-guiding tube and be responsible for high pitch, 4 metal sound-guiding tubes being arranged in surrounding are responsible for bass; The rear end of described metal sound-guiding tube is connected with corresponding dynamic iron unit sender by soft silica gel sound guide tube.The beneficial effects of the utility model are: 5 dynamic iron adopt 2 road frequency divisions, and the equilibrium realizing senior middle school's bass is arranged, and 5 sound guide tube inside, road can regulate sound dampening with different sound-absorbing material respectively, improve sense of hearing.Finally by the intensity of sound of the resistance adjustment 4 road sound guide tube of bass series connection in 4 tunnels, reaching deception brain sound is the illusion transmitted above, and rear people can think that people departs from forehead and sings before people's head, avoids effect in head.Achieve the effect expanding sound field, the sound field obtained closer to loud speaker is experienced.

Description

A kind of 5 conduit 5 unit combination move iron earphone

Technical field

The utility model relates to a kind of dynamic iron earphone, particularly relates to a kind of 5 conduit 5 unit combination and moves iron earphone.

Background technology

Existing domestic and international market multiple unit is moved iron earphone major part and is adopted the design of single sound guide tube, advantage is that structure is simple, shortcoming is that high bass unit can not adjust separately, many dynamic multiple sound mouths of iron often need design large cavity simultaneously, and large cavity easily causes sound localization problem when audio mixing, reduces resolution, the music major part of simultaneously listening due to us is loudspeaker design, listen with earplug and be positioned with effect in head, namely people's acoustic fix ranging all at people's forehead position, affects sense of hearing.

Utility model content

The purpose of this utility model overcomes deficiency of the prior art, and provide a kind of rational in infrastructure, 5 conduit 5 unit combination can improving sense of hearing move iron earphone.

This 5 conduit 5 unit combination move iron earphone, and comprise 5 independently metal sound-guiding tube and corresponding dynamic iron unit, be positioned at middle metal sound-guiding tube and be responsible for high pitch, 4 metal sound-guiding tubes being arranged in surrounding are responsible for bass; The rear end of described metal sound-guiding tube is connected with corresponding dynamic iron unit sender by soft silica gel sound guide tube.

As preferably: described dynamic iron unit is respectively middle bass S1, middle bass S2, middle bass S3, middle bass S4 and high pitch SH, and the metal sound-guiding tube that high pitch is responsible in described high pitch SH and centre is connected.

As preferably: after described middle bass S2 and middle bass S3 is in parallel with electric capacity C2, series resistance R2 is to signal source, after described middle bass S1 and middle bass S4 and electric capacity C3 parallel connection, series resistance R3 is to signal source, and high pitch SH series capacitance C1 is to signal source.

As preferably: described metal sound-guiding tube inside is filled with the sound-absorbing material changing sound dampening.

The beneficial effects of the utility model are: 5 dynamic iron adopt 2 road frequency divisions, and the equilibrium realizing senior middle school's bass is arranged, and 5 sound guide tube inside, road can regulate sound dampening with different sound-absorbing material respectively, improve sense of hearing.Finally by the intensity of sound of the resistance adjustment 4 road sound guide tube of bass series connection in 4 tunnels, reaching deception brain sound is the illusion transmitted above, and rear people can think that people departs from forehead and sings before people's head, avoids effect in head.Achieve the effect expanding sound field, the sound field obtained closer to loud speaker is experienced.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model will be described in conjunction with preferred embodiment, should know, not represent the utility model restriction in the described embodiment.On the contrary, the utility model will contain can be included in attached claims limit scope of the present utility model in alternative, modified model and equivalent.

As shown in Figures 1 to 4, this 5 conduit 5 unit combination move iron earphone, and comprise 5 independently metal sound-guiding tube 1 and corresponding dynamic iron unit, described metal sound-guiding tube 1 inside is filled with the sound-absorbing material changing sound dampening.Be positioned at middle metal sound-guiding tube 1 and be responsible for high pitch, 4 metal sound-guiding tubes 1 being arranged in surrounding are responsible for bass; The rear end of described metal sound-guiding tube 1 is connected with corresponding dynamic iron unit sender by soft silica gel sound guide tube 2

Described dynamic iron unit is respectively middle bass S1, middle bass S2, middle bass S3, middle bass S4 and high pitch SH, and the metal sound-guiding tube 1 that high pitch is responsible in described high pitch SH and centre is connected.After described middle bass S2 and middle bass S3 is in parallel with electric capacity C2, series resistance R2 is to signal source, and after described middle bass S1 and middle bass S4 and electric capacity C3 parallel connection, series resistance R3 is to signal source, and high pitch SH series capacitance C1 is to signal source.

Adopt 5 independent metal sound guide tubes 1, intermetallic metal sound guide tube 1 is responsible for high pitch, and 4 metal sound-guiding tubes 1 are responsible for middle bass, because in dynamic iron unit bass less use 4 unit, bass can promote the amount sense of bass greatly.Each dynamic iron unit is connected by frequency divider, and high pitch, by electric capacity frequency division, realizes a single order high pass, removes medium and low frequency, plays high frequency, and 4 basses are in parallel by two series windings two after resistance decrement, and last and Capacitance parallel connection, obtains a low pass frequency divider.Realize 2 road height cents frequently.Middle bass moves series resistance before iron, makes the intensity of sound in 4 metal sound-guiding tubes 1 different by regulating resistance.5 metal sound-guiding tube 1 inside can be put different sound-absorbing material and be produced sound dampening, regulate sense of hearing.
