Abstract
The utility model provides a kind of mobile phone demagnetization loudspeaker, comprise: support upper cover, support lower cover and the vibrating diaphragm be fixedly mounted between support upper cover, support lower cover, a toroidal inductor is provided with between described vibrating diaphragm and support upper cover, be provided with an annular vibration coil in the annular region of described induction coil, the sense of current passed through in described annular vibration coil is contrary with the sense of current passed through in induction coil.The utility model by being provided with the induction coil of annular between vibrating diaphragm and support upper cover, the vibrator coil that the direction that is energized with it is contrary is provided with in induction coil, two contrary coils in direction that are energized are utilized to produce contrary magnetic field, thus effectively eliminate the magnetic field exposure of primary coil, achieve the compatibility of Mobile phone horn and hearing aids, reach the compatibility of Mobile phone horn and hearing aids.
Description
Technical field
The utility model relates to Mobile phone horn, and what be specifically related to is a kind of mobile phone demagnetization loudspeaker.
Background technology
Along with the development of smart mobile phone and mobile Internet, the loudspeaker that smart mobile phone uses and the consumption of receiver increasing.And the radio wave that smart mobile phone sends can form electromagnetic field around antenna, this can make the people of hearing aids hear ear-piercing buzz.Traditional loudspeaker and earphone are all one block of magnet and the diaphragm structure with a wire bushing.When coil is by electroacoustic signal, the magnetic field changed, this magnetic field, with magnet effect, makes coil drive vibrating diaphragm to send the sound of our needs.But also the magnetic field of coil can interfere with the miscellaneous equipments such as hearing aids just, make miscellaneous equipment work abnormal or lost efficacy.Therefore the user of hearing aids is when using mobile phone, can there is compatible bad problem, can not hear clearly sound.
Utility model content
For this reason, the purpose of this utility model be to provide a kind of compatibility good, the user of hearing aids equipment can be made when using mobile phone, the mobile phone demagnetization loudspeaker knowing sound can be heard.
The purpose of this utility model is achieved through the following technical solutions.
A kind of mobile phone demagnetization loudspeaker, comprise: support upper cover, support lower cover and the vibrating diaphragm be fixedly mounted between support upper cover, support lower cover, a toroidal inductor is provided with between described vibrating diaphragm and support upper cover, be provided with an annular vibration coil in the annular region of described induction coil, the sense of current passed through in described annular vibration coil is contrary with the sense of current passed through in induction coil.
Further, described vibrator coil is in parallel with induction coil.
Further, in described vibrator coil, be provided with pole piece, described pole piece is provided with magnet steel.
Further, described support covers and is provided with a cannelure, described magnet steel correspondence is arranged in this cannelure.
The utility model compared with prior art, beneficial effect is: the mobile phone demagnetization loudspeaker that the utility model provides, by being provided with the induction coil of annular between vibrating diaphragm and support upper cover, the vibrator coil that the direction that is energized with it is contrary is provided with in induction coil, two contrary coils in direction that are energized are utilized to produce contrary magnetic field, thus effectively eliminate the magnetic field exposure of primary coil, achieve the compatibility of Mobile phone horn and hearing aids, reach the compatibility of Mobile phone horn and hearing aids.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cutaway view of the present utility model.
Identifier declaration in figure: support upper cover 11, cannelure 12, magnet steel 13, pole piece 14, vibrator coil 15, vibrating diaphragm 16, support lower cover 17, induction coil 18.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to shown in Fig. 1 ~ Fig. 2, Fig. 1 is structural representation of the present utility model; Fig. 2 is cutaway view of the present utility model.The present embodiment for current Mobile phone horn and hearing aid compatibility bad, the magnetic field that loudspeaker produce easily uses the problem producing interference to hearing aids, improve Mobile phone horn, to overcome hearing aid user when using mobile phone, compatible bad defect.
The mobile phone demagnetization loudspeaker that the present embodiment provides specifically comprise: support and the vibrating diaphragm 16 being arranged on internal stent, its medium-height trestle includes support upper cover 11 and support lower cover 17, and support upper cover 11 offers a cannelure 12.
Vibrating diaphragm 16 is between support upper cover 11 and support lower cover 17, vibrating diaphragm 16 is provided with a toroidal inductor 18, an annular vibration coil 15 is also provided with in the annular region of toroidal inductor 18, these two coils form concentric ring, and annular vibration coil 15 and toroidal inductor 18 are connected in parallel, the sense of current passed through therebetween is contrary.Toroidal inductor 18 is controlled by control circuit with the wiring of annular vibration coil 15, when by reverse current, induction coil 18 can produce a magnetic field of following vibrator coil 15 direction contrary, for eliminating the magnetic field exposure of vibrator coil 15, reduces Mobile phone horn to the electromagnetic interference of hearing aids.
In annular vibration coil 15, be provided with a pole piece 14, described pole piece 14 is provided with magnet steel 13, and magnet steel 13 correspondence be arranged in cannelure 12.
The utility model by vibrator coil by with induction coil electric current on the contrary, thus produce and induction coil magnetic field on the contrary, the electromagnetic interference of Mobile phone horn to hearing aid apparatus is eliminated with this, mobile phone products is allowed not need to revise sonic profile, when keeping good sounding effect, save the compatible authentication debugging time of mobile phone and hearing aids.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
