Abstract
The utility model discloses an excitation earphone, including two earphone vibrating diaphragms, magnetic conduction ring, set up in the intra -annular conducting magnetic column of magnetic conduction, set up in magnetic conduction ring with between the conducting magnetic column and respectively with two the voice coil loudspeaker voice coil lead wire of an end -to -end connection of earphone vibrating diaphragm still includes: two flux sleeves and excitation coil, excitation coil and power electric connection and set up in the magnetic conduction ring the flux sleeve reaches the conducting magnetic column encloses in the space of establishing. The utility model provides an excitation earphone, the principle and the dc supply mode of adoption electro -magnet add a coil on high permeability material to this accomplishes traditional permanent magnet, and not only tone quality can be adjusted wantonly, moreover simple structure.
Description
Technical field
The utility model relates to earphone, especially, relates to a kind of excitation earphone.
Background technology
The operation principle of current conventional earphone is because the voice coil loudspeaker voice coil in permanent magnetic field drives, and the vibrating diaphragm motion coil be in permanent magnetic field be attached thereto is connected with vibrating diaphragm.Coil drives vibrating diaphragm and sounds under the driving of signal code.Because the structure solidification of conventional earphone forms, tonequality is single, unadjustable.
Utility model content
The utility model object is to provide a kind of excitation earphone, to solve single, the uncontrollable problem of tonequality in prior art.
For achieving the above object, the utility model provides a kind of excitation earphone, comprise two earphone diaphragms, magnetic guiding loop, the conducting magnetic column be arranged in magnetic guiding loop, to be arranged between described magnetic guiding loop with described conducting magnetic column and the voice coil leads be connected with an end of two described earphone diaphragms respectively, also comprise: two flux sleeves and magnet exciting coil, described magnet exciting coil and power supply are electrically connected and are arranged in space that described magnetic guiding loop, described flux sleeve and described conducting magnetic column enclose.
Further, the utility model provides a kind of excitation earphone, and wherein, described voice coil leads and described power supply are electrically connected.
Further, the utility model provides a kind of excitation earphone, and wherein, described conducting magnetic column is set to N pole, and described magnetic guiding loop is set to S pole.
The utility model has following beneficial effect: the utility model provides a kind of excitation earphone, adopt principle and the direct current supply mode of electromagnet, high permeability material adds a coil, completes traditional permanent magnet with this, not only tonequality can regulate arbitrarily, and structure is simple.
Accompanying drawing explanation
Below with reference to figure, the utility model is described in further detail.The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model preferred embodiment
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Refer to Fig. 1, preferred embodiment of the present utility model provides a kind of excitation earphone, comprises two earphone diaphragms 101, magnetic guiding loop 102, the conducting magnetic column 105 be arranged in magnetic guiding loop 102, voice coil leads 106.
Wherein, described voice coil leads 106 is arranged between magnetic guiding loop 102 and conducting magnetic column 105, described and be connected with an end of two earphone diaphragms 101 respectively.
Again, this excitation earphone also comprises: two flux sleeves 104 and magnet exciting coil 103, described magnet exciting coil 103 is electrically connected respectively with the both positive and negative polarity of power supply 107, and this magnet exciting coil 103 is arranged in the space that magnetic guiding loop 102, flux sleeve 104 and conducting magnetic column 105 enclose.Magnet exciting coil 103 respectively with the both positive and negative polarity Electrode connection of power supply, conducting magnetic column 105 and magnetic guiding loop 102 can exchange polarity according to user personality demand, i.e. S/N exchange.
Moreover described voice coil leads 106 is electrically connected with the both positive and negative polarity of power supply respectively, described conducting magnetic column 105 is set to N pole, and described magnetic guiding loop 102 is set to S pole.Voice coil leads 106 is connected with an end of two earphone diaphragms 101 respectively, the earphone diaphragm 101 be attached thereto moves, and be connected with earphone diaphragm 101 due to the voice coil leads 106 be in permanent magnetic field, magnet exciting coil 103 drives earphone diaphragm 101 vibrate and sound under the driving of signal code.
As can be seen from the above description, the utility model the above embodiments achieve following technique effect:
The utility model provides a kind of excitation earphone, and adopt principle and the direct current supply mode of electromagnet, high permeability material adds a magnet exciting coil 103, completes traditional permanent magnet with this, not only tonequality can regulate arbitrarily, and structure is simple.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model; For a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
