Description
Technical field
The present invention relates to a kind of headphone, particularly a kind of Multi-armature-unit headset.
Background technology
Headphone is a kind of equipment for listoning music on user Dai Yutou, and it has the advantages such as sound field is good, comfort level good, protection duct compared to PlayGear Stealth.In addition, present young man, in order to follow the fashion and obtain better sense of hearing, also has more people to select to buy headphone.
Consider that the voice output efficiency of single dynamic iron unit is lower, if and adopt multiple dynamic iron unit, cost is higher again, therefore, current headphone is all with the driven unit of moving-coil unit composition earphone, carry out the transmission of voice signal, and dynamic iron unit is mostly used in the relatively expensive In-Ear Headphones of price, not adopt by headphone.
But, along with the extensive use of dynamic iron unit, its use cost obtains reduction, and consider the advantage of dynamic iron unit compared to moving-coil unit, impedance as moving-coil unit is higher, dynamic iron unit is compared to its more power saving, the sound that frequency range is abundant can also be formed after the dynamic iron unit combination of and for example multiple different frequency range, bring more three-dimensional sound experience, if therefore can traditional moving-coil unit be replaced completely with dynamic iron unit and be used in headphone, so this new headphone certainly will have quite significant progressive compared to traditional headphone.
Summary of the invention
Object of the present invention is exactly for the problems referred to above, provides a kind of dynamic iron unit of multiband that adopts to replace the Multi-armature-unit headset of moving-coil unit, and it can power saving and can bring more three-dimensional sound experience for hearer.
To achieve these goals, the invention provides following technical scheme: Multi-armature-unit headset, the driven unit comprising left auricular concha, auris dextra shell, ear band, wire and ear pad and be installed in left auricular concha and auris dextra shell, this driven unit comprises: low frequency moves iron unit, to be arranged in left auricular concha and auris dextra shell and to be fixedly connected with the inwall of left auricular concha with auris dextra shell, being respectively provided to few this low frequency in left auricular concha and auris dextra shell and moving iron unit; High frequency moves iron unit and/or intermediate frequency moves iron unit, to be arranged in left auricular concha and auris dextra shell and to be fixedly connected with the inwall of left auricular concha with auris dextra shell, being respectively provided to few this high frequency in left auricular concha and auris dextra shell and moving iron unit and/or at least one this intermediate frequency moves iron unit; Frequency unit, be arranged in left auricular concha and auris dextra shell, low frequency moves iron unit and high frequency moves outside space that iron unit and/or intermediate frequency move between iron unit and be fixedly connected with the inwall of left auricular concha with auris dextra shell, this frequency unit moves iron unit and high frequency respectively and moves iron unit and/or intermediate frequency and move iron unit and be electrically connected with low frequency, be respectively provided to few this frequency unit in left auricular concha and auris dextra shell.
Further, above-mentioned low frequency moves iron unit and is arranged between two parties in left auricular concha and auris dextra shell.
Again further, above-mentioned high frequency moves iron unit and intermediate frequency and moves iron unit and be distributed in the surrounding that low frequency moves iron unit.
Further, above-mentioned frequency unit is arranged at top or the below that low frequency moves iron unit.
Alternatively, above-mentioned frequency unit is arranged at high frequency and moves top or the below that iron unit or intermediate frequency move iron unit.
Further, above-mentioned low frequency moves iron unit, high frequency moves iron unit, intermediate frequency moves iron unit and the inwall of frequency unit and described left auricular concha and auris dextra shell welds or bonding.
The beneficial effect of above technical scheme is adopted to be:
The invention provides a kind of Multi-armature-unit headset, its difference with the prior art is: driven unit includes that low frequency moves iron unit, high frequency moves iron unit and/or intermediate frequency moves iron unit and frequency unit, these unit to be all installed in left auricular concha and auris dextra shell and to be fixedly connected with the inwall of left auricular concha with auris dextra shell, and low frequency moves iron unit, high frequency moves iron unit and/or intermediate frequency moves iron unit and is electrically connected with frequency unit respectively; The compared with prior art acquired progress of this distinguishing characteristics is: so that how dynamic iron unit replaces traditional moving-coil unit, its conversion efficiency is high, solve the problem that impedance caused by the characteristic of moving-coil unit self is high, reduce energy consumption, achieve the object of more power saving, the dynamic iron unit of multiple frequency range brings the output of the sound of different frequency range respectively in addition, it exports each speaker unit to respectively by frequency unit, define the sound of frequency range more horn of plenty, thus bring more three-dimensional sound experience for hearer.
