Description
Technical field
The utility model relates to loudspeaker technical field, relates in particular to the high-tone-quality mobile phone loudspeaker that a kind of demagnetization is dust-proof.
Background technology
Communication equipment is the indispensable electronic product of modern, especially mobile phone, along with the development of smart mobile phone and mobile Internet, the loudspeaker that smart mobile phone uses and the consumption of receiver increasing.But there is following defect in current Mobile phone horn:
1, the volume of Mobile phone horn operatic tunes after producing just secures, and in order to save space, in actual design, the volume of the operatic tunes is often restricted, cause Mobile phone horn in use low-and high-frequency performance cannot meet the demands, tonequality is bad;
2, mobile phone in use, and the radio wave that mobile phone sends can form electromagnetic field around antenna, and 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;
3, mobile phone shell is positioned at loudspeaker position and has some penetrable sound holes, to ensure that sound can not stop and cut down; But these penetrable sound holes just, but become the passage that dust enters interior of mobile phone; Long-term a large amount of dusts enters loudspeaker position, not only affects communication effect in the past, and because be attached to ear limit when receiving calls, also there is the potential risk spread disease germs.
Utility model content
For the defect of above-mentioned prior art, the high-tone-quality mobile phone loudspeaker that the utility model provides a kind of demagnetization dust-proof, effectively can eliminate the interference in magnetic field, good dustproof effect, tonequality is good.
For achieving the above object, technical solution adopted in the utility model is:
The high-tone-quality mobile phone loudspeaker that a kind of demagnetization is dust-proof, comprise support arm, inner support, protecgulum, bonnet, vibrating diaphragm, described inner support is arranged on the inner chamber of support arm, described vibrating diaphragm is arranged on the upper end of inner support, within the inner chamber being positioned at support arm, the upper end of described inner support is provided with toroidal inductor, be provided with an annular vibration coil in the annular region of described toroidal inductor, the sense of current passed through in described annular vibration coil is contrary with the sense of current passed through in toroidal inductor; Protecgulum and bonnet are socketed in outside support arm, protecgulum and rear interior surface and support arm outer surface blind-mate, and protecgulum and bonnet can move up and down along support arm; Described protecgulum and bonnet coordinate with support arm and form the front operatic tunes and the rear operatic tunes respectively.
As the improvement to technique scheme, described annular vibration coil is in parallel with toroidal inductor.
As the improvement to technique scheme, be provided with pole piece in described annular vibration coil, described pole piece is provided with magnet steel.
As the improvement to technique scheme, protecgulum and rear interior surface and support arm outer surface pass through threaded engagement.
As the improvement to technique scheme, protecgulum and bonnet are equipped with several penetrable sound holes.
As the improvement to technique scheme, described protecgulum and rear exterior surface are coated with Air Filter.
Compared with prior art, the beneficial effect acquired by the utility model is:
The high-tone-quality mobile phone loudspeaker that the demagnetization that the utility model provides is dust-proof, by being provided with toroidal inductor between vibrating diaphragm and support upper cover, the annular vibration coil that the direction that is energized with it is contrary is provided with in toroidal inductor, 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.
Mobile phone horn can regulate the volume size of the front operatic tunes and the rear operatic tunes by the position adjusting protecgulum and bonnet, to reach the object regulating Mobile phone horn low-and high-frequency performance, can meet low-and high-frequency requirements different in use; Protecgulum and bonnet are provided with Air Filter, effectively prevent dust from entering interior of mobile phone.The high-tone-quality mobile phone loudspeaker that demagnetization of the present utility model is dust-proof, effectively can eliminate the interference in magnetic field, good dustproof effect, tonequality is good.
